[Elecraft] future ham gear and Sound perception
Future ham gear, given our advancing ages, should include: -larger and single function buttons for Parkinsons folks, and everyone else, too. -high freq audio boost and eq. and balance control to feed more to one ear than the other. -footswitch option is easy to add (feet work, hands do not). -LARGE dial and large clear-contrast print on sw labels. -Big RTTY/data readout on front pannel for those that can not hear much anymore or for those whose speech is now impaired. -Lots of automatic functions for often-repeated items. Notice now few of these factors are on the K3, sad to say. 73, Charles Harpole [EMAIL PROTECTED] From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: Re: [Elecraft] Sound perception Date: Tue, 4 Nov 2008 20:00:58 + CC: elecraft@mailman.qth.net On Nov 4, 2008, at 6:12 PM, Jim Miller wrote: IMHO, Sound perception is probably one of the most variable things of all. For instance, MY hearing is 10 dB down up to about 1500 Hz and by 1700 Hz it is 50 dB down for the remainder of the spectrum. I asked the audiologist what was considered totally deaf - she said 70 dB was deaf. (and I thought I could hear just fine, almost, except for my wife (higher frequency and softer voice)and I didn't need to hear her anyway, LOL) Does anyone think the way I adjust my audio would be the same as the way they like it. I doubt it. Trying to answer a question of what is the best for audio for any one person OR situation is virtually impossible. I do use the original Heil headset with the HC4 element and the original Goldline with the HC5 and full-range elements. Well, there are two parts to this. One is a function of frequency response and the other is a function of distortion products. Many of us are suffering from varying degrees of hearing loss. I suffer from tinnitus (ringing of the ears) which can mask some of the high- frequency content from the voice, usually women's voices. (My wife occasionally accuses me of selective hearing. :-) Anyway, I do benefit from using headphones and providing a bit of a boost to the higher frequencies, e.g. starting at around 1KHz with boost increasing to around +6dB at 3KHz. You can make this sort of improvement with a graphical or parametric equalizer. (I prefer parametric myself but they are hard to come by.) Distortion products typically impart either a warm, fat sound; i.e. low order, mostly 2nd harmonic; or a hard, edgy sound; i.e. high order. Either can obscure readability to some extent. One of the reasons the old tube rigs were so pleasant to listen to is because they had almost no high-order distortion. It was almost all 2nd and a touch of 3rd. I could listen to my Hammerlund HQ-180X all day and all night very happily with no ear fatigue. If you suffer from that hard, edgy, fatiguing sound, try stealing the signal before it gets to the built-in audio amp and feed it to a good hi-fi amp to see what you hear. Get the signal right from the detector if you can. It can make a *huge* difference. (My experience is that most manufacturers of ham gear really skimp on the quality of the audio chain.)

[Elecraft] OT: KP5 and 60m
It is announced that the upcoming DXpedition to KP5, Descheo Island, plans to use 60meter band. This is a mistaken use of this band because 1. it was justified to FCC to be awarded to ham radio as an EMERGENCY BAND, not a DX band. 2. it wil obviously be overloaded in the extreme, having nearly 24 hr openings to the States, leading to sigs out of the sliver bands as ops desperately try to be a little off freq to get the DX's attention. 3. It gives casual ops another reason to condemn DXpeditions because, in this case, the whole band is likely to be occupied with KP5. This is the biggest zoo of all time waiting to happen. It is no accident that ARRL currently sez it will not credit award contacts on this band. I hope more responsible minds will see the error of this way and retract that use. 73, Charles Harpole [EMAIL PROTECTED] ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

The K3 is a joy to use as is for every type of operating I do. I do use a logging program for contesting, of course, and it displays K3 frequency and mode. It can also change them. I don't use that capability for routine band/mode changes, preferring the front panel of the K3. I do use point and shoot to capture multipliers and that sometimes commands a band change.

RE: [Elecraft] RE: K3 is really a computer radio 3
Thanks for ur advice which I already took. I got a FT-9000d which has so many knobs and switches that it may set the all time record. For operating ease, the Yaesu is far superior and already contains most of the features on the Elecrafters wish lists. I just wanted to give the K3 a thorough chance to show its stuff and was frustrated at the difficulty of operation. I was also able to switch the same antenna between the 9000d and the K3. In all cases the performance on 80 and 160 was the same with noise and vy weak sigs. Considering the vast price difference, that makes the K3 the bargain of the decade, even if u add the cost of a computer to control it. 73 Charles Harpole [EMAIL PROTECTED] Date: Sun, 19 Oct 2008 20:48:18 -0700 To: elecraft@mailman.qth.net From: [EMAIL PROTECTED] Subject: [Elecraft] RE: K3 is really a computer radio Oh, for band stacking registers and band buttons.

Phil, my outlook on those operations is different, though I accept your point that they are another venue outside ham radio where Morse operations take place (rarely). I'm very familiar with the wonderful efforts of RD and the others at www.radiomarine.org , including the several times each year that they do a very limited revival of operations from what's left of a couple of famous Pacific Coast stations, often in conjunction with some old Victory or Liberty museum ship whose Morse station has been activated for the special event. But it is all essentially a historical reenactment by historical preservationist groups. Bona fide profit- and safety-driven commercial Morse operations in the USA ended on 12 July 1999. As interesting and laudable as these reenactments are, they do not represent any remnant of the originals that continues to serve real commercial and regulatory (SOLAS) requirements. It is odd but true that the FCC will still license stations and operators for this service, although Second Class Radiotelegraph licenses have had greatly reduced Morse exam requirements for about 25 years, since the FCC allowed crediting the very simple Amateur Extra Morse exam to the commercial ticket. But the FCC also continued to offer the Aircraft Radiotelegraph Operator exam and endorsement for decades after the last aircraft radiotelegraph operator position had been eliminated, so it's anyone's guess how many decades these other obsolete tickets will be issued.

The most severe problem I have is: a) the output power spikes and overshoots in CW or SSB or FM as you adjust the power control, so it is not advisable to use a sensitive, i.e solid state power amplifier with the K3. Especially not one needing less than 50W of drive. It needs a fast responding meter to see it. A work around is to set the power without the amplifier in circuit, speak or key to let the spike happen, then switch on the PA and not adjust power or mode afterwards. Does this not happen to anyone else? A lesser problem is: b) that the power output is unstable once set in SSB mode, showing variations of around 50-100% in the peak output depending on the power output setting. This is when set up as described. It is only really visible with a peak reading power meter. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 AGC is better now
My K3 is back from factory and the AGC now works better at handling pile ups where many callers formerly were reduced to the same audio level. Now, it is easier to pick out calls among many callers. Not absolutely great, but better. Can anyone recommend the best menu setting for max discrimination among many callers at same time?

[Elecraft] SSB version: 3 rigs compared
SSB OPERATIONAL test opinion-- All tests done with max use of all controls to give best sig... so each rig was adjusted differently but to the best function I could obtain for each rig: First test is on a very weak ssb sig with qsb (just barely readable): 9= fully readable for a good contest exchange, ng for rag chew. DNR slow on uptake (a fraction of time before DNR kicked in when the sig first comes on, but after that, very readable with pinched audio range). DNR used with Contour which boosted audio output and increased copy. Without DNR, wider audio but reduced readability and no delay. u-Tune always on at center setting. 3= ok for contest, ng rag chew. K3 had to have a discernable level of more band noises to give same readabilty, and with NR on, audio is also decidedly pinched. NB on mid-range; NR made copy discernably worse at all settings, some more than others. 1= Just not as sensitive, about 80% where other two were 90%; using NB at 5H worked better, NR no help at all, so was kept off. Listening included lots of live band noise to go with lesser signal. When live band noise went down (as tho band is going out), the desired sig was more readable proportionally --readable beyond what one would expect. As on CW, the ONE delivered a more pleasant sounding sig than the other two, but only when the sig built up to move the S meter; otherwise, I missed more % of copy. Weak sig sum... 9 most comfortable to listen to, but 3 very close behind. 1 got nice only with stronger sigs. Lightning on horizon and other Noises: 9= Pinched audio is there, but the punch of the static crashes were bearable. u-Tune and DNR and Contour on. 3=Static crashes caused a kind of pumping with NB and NR on and adjusted to damp the crashes (AGC on fast really was uncomfortable; slow, more bearable). NB alone was best for readability, but the crashes were definitely worse in sharp peaks of noise. Higher pitch band noise than other two, ORION 1 bass helped somewhat, see below. 1= More bass made noise more bearable. Used NB 5H; but switching the NR1 on with this vy weak sig just cut the rcvr output to zero. With only NB 5H, bass crashes hurt ears less than 9 and K3. However, total sig readability was not as good, and in fact, the reallyweak sig was discernable but not readable in QSB nulls (not as gud as other two). Overall SSB usage: The FT9000d was the SSB rig I wanted to listen to for weak sigs on 20m SSB. K3 was a close second, but the K3 will spoil u with its superior CW rcvr and leave you wanting on SSBdue to the contrast with CW if nothing else. Strong sigs sounded more natural and pleasant on the Orion One where the strong sig overcame band noise and lightning static. IF I HAD TO KEEP ONLY ONE: it would be the 9000d because I do mostly SSB and I REALLY enjoy all the knobs and especially the reasonably functional bandscope. Using the K3 after the 9000 made me search the k3 dial for more info. If I did CW mostly, I would try to add more visuals, remote keypad/tune knob etc. to the K3 via after market gagets and use only the K3 because it is a CW dream machine. ORION has vy nice remote keypad/tuning knob and is unique with TWO amplifier keying lines, vy vy nice. Overall, for this appliance operator speaking, the FT9000d is just plain more fun, looking at it, touching it, and using it. 73, end of this opinion stuff. PS: Tnx to DF0HQ whose CQ contest calls provided over 4 hours of perfectly consistent sig levels--weak with QSB, and thanks too to the weather for the correctly-distant lightning static. FT-9000d just in from factory; K3 just back from factory; and ORION ONE is old and using version 1.373b5 (sure wish I cudda included a brand new O TWO). Only other rigs that shoulda been included are IC-7800, 7700, and maybe the OMNI 7.

Sensitivity: 9=hiss was high pitched and somewhat irritating (no sig) with sig, hiss not discernable. 3= most quiet with no sig, more base in audio. 1=similar base, higher hiss than 3, but sigs above S-6 sounded vy natural. All three on vy weak sig could not discern any difference. NR alone: 9= good result but slow processor (?) caused some blasting when NR knob turned. highest setting kills most hiss.

NB alone: 9=vy gud on ignition noise, kills all; no effect on other noises all knob settings. 3= IF wide 7 gives some chop on sigs, otherwise good. DSP T3-7 same chop. Lower both settings-no effect on no signal condx. no automobile near by. 1= H only- no effect on no sig condx; H + 9 gave same result, no car near. u Tune 9=Absolutly great, kills many kinds of noise and BCI.

eBay has become a mess. I have won bids on goods that did not exist and fortunately waited to pay until the seller confirmed many things for me. Some will grab someone else's sales notice and repeat it as tho it were their own, thinking some will simply pay without confirming anything with the seller. Friends tell me this is rampant. Today, I still trust eHam sellers, but hope the trash folks do not find it. PS Many legitimate vendors will ship overseas but want an Am credit card with an American card billing address.

But it is a real problem for us overseas people. Many firms will not ship abroad at all and others insist on using expensive couriers, even for items only costing a few $. My recent problem trying to get a 15-way cable for example. It would cost $10 for the cable and $60 to ship it, and that is before customs charges. There is a solution for more expensive items, the shipping agent. E.g. USABox, MyMailbox USA etc. These companies will for a charge give you a US mailing address, take your package and forward it by DHL/UPS or occasionally USPS. The shipping cost plus their fee works out at about the same as the standard courier charge, so for an item worth more than few $100s it is worthwhile. Some will even buy the item for you for a 10% commission. Mike Mike Short wrote: And if he was willing to ship overseas, would have probably got a few hundred more. It escapes me why people won't ship overseas. One customs form, and you are done. All the work is on the receiving end. I have sold equipment overseas for 100-300 more than the last US offer.

RE: [Elecraft] K-3 Contest agc settings
Get Elecraft to fix ur radio so that the AGC works better, early versions out of the box necessitated turning off AGC and riding RF Gain, like the first DXpeditioners did.

Jacks articles were a big help with understanding what is going on ( cliffton labs ). If I am play with weak DX signals, I tend to keep the AGC levels a bit hard, meaning louder. Low signals low, high signals high. I have also used this, and RF gain together in a contest, to dig weaker signals out between the big guns. When in the midst of lots of big guns, I have to flatten the signals out so that my ears are not shorted out by the big signals coming in.

However mine are SLP= 8 and THR= 4 and, to me, it sounds pretty close to the K2. I don't use NR much on CW because of what it appears to do to the received CW signals.

I chose to reply to the list because this is a topic of interest to many, whether contesting or not. What AGC settings are you using? In sprint last night I used the K-3 (first real contest) and I was less than thrilled with rx performance. Close by stations seemed to overload the rx. Something I didnt have with my MKV with the inrad mods and filters. Been fiddling with the settings but obviously dont have it right. All my operating is contesting and I've used two K3s for a year now. At home, there are several local contesters just a few miles line-of-sight off the back lobes of my Yagis. At 1.5 KW they saturate my S-meters. Still, they are unnoticeable when outside my filters and I'm usually run the default AGC settings. Most people have reported just the opposite comparison between the MKV and K3, i.e., they prefer the K3 RX in contest or crowded band conditions with strong signals nearby. The PREamp has more impact on RX overload than the AGC in most cases. On the low bands, you may even need to engage the ATTenuator. Don't make the AGC do all the work by slamming it with too much signal strength. Certainly, you can optimize the AGC for different conditions by changing the threshold and slope. For many it is a matter of personal preference more than an absolute correct setting. You will probably want higher thresholds on the lower bands due to the noise level. The slope is a trade-off between reducing gain for strong signals and still having discrimination between different signal strengths. If you keep the front-end tamed down with appropriate PRE and ATT engagements, then you will find the AGC gives you fine control over the range of signal strengths rather than relying on it alone for dealing with the very strong signals. filters in rig 2.8, 1.8 and 250 Remember your 250 filter is really 370 Hz at the -6 dB points, so you might have it engage at DSP bandwidth of 350 or 300 Hz. But even at 350, the cascade effect will produce an overall bandwidth of less than 300 Hz, which is a bit narrow for CW contesting, IMO. At DSP WIDTHs of 400-500 Hz, your roofing filter will be the 1.8 kHz, if you have it configured normally, so that doesn't give you IMD protection for the DSP with very strong signals located between your DSP and crystal filter widths. (I should point out that some K3 ops don't subscribe to the K3 design that deploys the crystal filters as roofing filters that are set wider than the DSP WIDTHs to protect the DSP. Instead they prefer the passband shape of the crystal filter and effectively eliminate the DSP filter by configuring their K3 filtering to have the crystal filter engage at DSP bandwidths GREATER than the crystal filter. Until the DSP WIDTH is reduced to well within the crystal filter bandwidth, the crystal filter is dominating the passband shape and filtering. Of course, the DSP will still provide steeper skirts at a point well below the passband.) 73, Ed - W0YK P.S. Thanks for the Sprint Qs! ___ Elecraft mailing list
[Elecraft] Heil life

Even if it didn't help with weak signals on SSB, it certainly made listening more pleasant. With recent firmware, however, I have to agree that NR is a bummer. It always makes signals less pleasant to listen to on SSB regardless of setting. Any way to restore the old performance? Dick KA1SA #911 I was the one asking for a comparison, and I received two replies, each one saying that the external speaker (two different brands) they were using was an improvement over the K3's noise reduction. I ordered one, and sure enough, it's better. It seems that any NR system is far from perfect however. But now my external NR gives me some relief from the constant grind I have. I had quit using the K3's NR not only because it wasn't helping on SSB, but also because if I had been using it, the AF gain had to be set so high that the next time I powered up the radio I was blasted out of my chair because it powers up with NR off, even if it was on before. So I'll use the outboard NR until the K3's NR becomes satisfactory for me. If it ever does, I'll offer my NR speaker to some unfortunate OM with a lesser radio.

[Elecraft] evolution of goals , now low noise
I remember that in the 1950-60s, hams sought more sensitivity in their rcvrs. That solved, then later the chase changed into a search for greater selectivity. Thus INRAD and roofing filters, passband tuning and notches. Now in our rf poluted world, we seek noise limitations and control. The IC-775DSP for example, has a noise function designed just for the Russian Woodpecker. That thankfully gone, now we want a limiter on all that other noise. 73 Charles Harpole [EMAIL PROTECTED] From: [EMAIL PROTECTED] To: elecraft@mailman.qth.net Date: Tue, 19 Aug 2008 00:40:40 -0700 Subject: Re: [Elecraft] K3 noise blanker On Sun, 17 Aug 2008 21:30:26 +0100, Stephen Prior wrote: The NB is, it seems to me, no better than many others I have used (eg TS-850) and the NR does not seem, to me at least, to be any better than that on the TS-480 this K3 replaced.

[Elecraft] little OT: sweating the details
Every now and then, I read every message placed on several ham radio reflectors. I am astonished at 1. the high level of detail that some hams worry about and 2. the low level of basic knowledge that the ham test should have caught and finally 3. the seeming unwillingness to just go ahead and try something instead of asking permission from those who know more (see the quote marks?). HAM radio: in the golden days of the 1956 sunspot peak, hams threw wires in trees, loaded up metal drain downspouts, ran something until it smoked and then wired in something of higher capacity and ran it again. In those days, I never hrd anyone asking if something will work perfectly (after extensive computer modeling, etc.-- yes, I know there were no home computers then) or if some hot shot op already had the thing under discussion. Then, hams just did it. I long for those days, so lacking a time machine, I will just again use the delete function more often. 73 Charles Harpole [EMAIL PROTECTED] From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Date: Sat, 16 Aug 2008 13:51:49 +0100 Subject: Re: [Elecraft] K3 Headset Audio - Is this correct ?

Tony, N2TK wrote: Is it recommended to hook up the BNC connector on the back to the KRX3 or to use the second SO-239 on the K3 or does it make any difference? Hi Tony, If you have a KAT3, you can optionally use the non-transmit KAT3 antenna (which might be ANT1 or ANT2 at any given time) as the sub receiver's secondary antenna source. If not, you'll need to use the BNC jack. The BNC jack is recommended anyway, and an appropriate cable is supplied with the KRX3 module. It's the way we set up factory-built K3s. It's more flexible, because you can connect a receive-only antenna for use with the sub receiver that is well-isolated from your transmit antennas. (Physical and electrical isolation for a receive antenna is good practice in general.) If you don't have a special RX antenna for use with the sub receiver, but you do have two antennas connected (to ANT1 and ANT2), the KAT3 non-transmit antenna might be a better choice. This selection has no impact on *shared* use of the main antenna by the sub receiver. You can do that in any case. Most of the time I will be using the same antenna for both receivers. That's the shared case. When the K3 has the capability of having the two receivers on two different bands I would like to monitor another band with a second antenna. An example would be to monitor 6M. Figured I could use the second SO-239 for this. Either the KAT3 non-transmit antenna or the BNC jack would work. If you use the KAT3 non-transmit antenna, be sure to keep the antennas on ANT1 and ANT2 very well isolated so the sub receiver's carrier-operated relay doesn't get triggered when you transmit. I assume that when I am listening to both receivers on the same band that if I am using the receive antenna input the receive antenna will go to both receivers. Is this correct? Yes. 73, Wayne N6KR ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] bnc connector
Most hams know that the standard BNC (not the mini version) should handle 200-300 watts and not be pushed higher, altho likely will go higher for some time. The So-239 is often rated at a Kilowatt of RF but clearly takes double that in many many shacks. However, at about 6 KW with a small SWR, the SO-239 will begin to arc the pin to shield. The big one that looks something like a BNC, called an N, has many advantages including taking higher RF, presenting a lower SWR bump in the line, greater shielding of the shield line, and a nice twist and pull release removal method (or screw on versions, too). These are seen on antennas for 440 and above often (like Hustler). However, they are even harder to install/solder especially if u try to keep the O ring that resists water entry in place. Forget the SMA for ham RF applications. GL, and I mean, GL...

Elecraft K3 front mic socket (8 pin) is basically Kenwood standard, but Elecraft forgot to check the full pin-out and mistakenly reversed two pins that are used only on Kenwood hand mics and others not usually in the HF ham shack.

I read about some difference in Kenwood vs. the K3's pinout and now this. See Bob's replay to my query below. So who is confused? I sure am. Hi Steve Thanks for your note. Yes, there IS confusion because Elecraft began as a kit primarily. They suggested you follow Kenwood pin out but as you built it that was so nice and easy to change. They went to a Yaesu configuration with the K3. There is no confusion here. Yaesu. Never was anything else that I knew of. That works well. Ten Tec is using this same pin out and several of the QRP kits are following that so this is all good Steve. As far as our products - ANY of the dynamic elements work so for the headset, you use the AD-1Y (Yaesu) adapter and the headset using our HC 5 element. This is a terrific combination. The AD-1Y adapter has a 1/4 female output for the HS 2 or FS 2 PTT control. For microphones I would look at the PR 781 or GOLDLINE GM 5. Cable is the CC-1Y and again that has output for the PTT control of our handswitch of footswitch. Hope this helps. Let me know how best I can help form here, Steve.

I use my SM-220 ONLY for monitoring the RF output from my station. Period. However, if I recall, both the SM-220 and SM-230 have some provisions for displaying the IF output from a receive IF that IF output has been properly converted to the input of the IF input section of the monitor. I cannot say whether either of these monitors would be worthwhile for the displaying of a usable IF output from the K3. You'll have to get that info from someone much more knowledgeable than I. However, I cannot recommend these monitors highly enough for helping to keep track of your transmitted signal. I've had an output RF monitor for the past 40 years and cannot imagine operating my station without having one available. They have found 'problems' I'd probably never have noticed had I not had one available. 73, Tom Hammond N0SS At 14:56 08/02/2008, Timothy Raymer wrote: Keith, I know Tom, N0SS, has has an SM-230 in line for quite some time.

The Kx is pretty good about not making ugly electrons, but the amplifier you drive over the edge could. The other thing I remember about the SM-230 and Tom's station is that it induced some strange SWR issues by the time we got up to 28Mhz. Combination of lengths of coax, impedance of the unit itself, and a few other oddities caused a bit of a problem for a contest a few years ago.

That way, if the bottle breaks, u do not have 12 oz of ball bearings raining down on ur or ur neighbor's heads. Also, for the times u miss and the water bottle gets hung up in a tree, when it finally comes loose, all u get is a little wet and a light plastic bottle coming down!

RE: [Elecraft] K3 Need for compressor?
How about just using a good mic that is dead to its back and thus leaves out virtually all fan noise? Charles Harpole [EMAIL PROTECTED] Date: Thu, 29 May 2008 08:10:32 +0100 To: elecraft@mailman.qth.net From: [EMAIL PROTECTED] Subject: Re: [Elecraft] K3 Need for compressor n4lq wrote: It seems that without the compressor it is difficult to obtain full SSB output. I'm listening to a guy right now on 160m in QSO. He had is compression on and as can be expected, was picking up plenty of fan noise from his amplifier. He was advised to turn off the compression. This he did and the fan noise went away but he complained about insufficient drive to his amp and his K3 was only putting out 38 watts now. I don't have a decent peak reading wattmeter but I think weak RF output is a common complaint. It's rather surprising that the K3 doesn't have the option of a peak-holding RF output display, like the S-meter has. I just wonder if Elecraft expects everyone to run some degree of compression? Or are we interpreting the PWR meter on the K3 incorrectly? Mainly the latter. When the K3 says no compression, it's telling the truth. In contrast, most other rigs are using compression all the time - even when the speech processor is turned off - because there is peak limiting due to heavy ALC. The K3 is one of the few rigs that does it right... and because no good deed goes unpunished, it then suffers complaints of weak audio! To equal the compression that's always taking place in most other rigs, you probably *do* need to turn the K3's compression up a little. No harm in that - unlike most other rigs, a moderate amount of compression will simply make you sound louder. However, the complaint about fan noise is a valid one. As the compression is increased, the peak audio stays the same but the background noise comes up. Any transmitter with effective compression will also benefit from a noise gate or some other kind of nonlinear threshold, to reduce the noise background when there's no actual speech. This would be something like VOX, but with a different configurable threshold and hold/release dynamics. To obtain full value from the K3's highly effective compressor, could a noise gate be added to 'Lyle's List', please? -- 73 from Ian GM3SEK http://www.ifwtech.co.uk/g3sek ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] cold flow
Cold flow is an interesting factor hams must know about. Many plastics and things with placastizers in them (I failed 7th grade spelling) will change shape over time when put under pressure. The inner isulation of coax is a major item... when coax is bent, the inner insulator (and the outer one also) changes shape the more sharp the bend and the longer it is bent the greater the cold flow changes. Tell that to the cable guy who routinely puts coax in 90degree bends and staples them tightly into that shape. 9913 is particularly at risk due to its spiral plastic string inside. Some coax data charts will tell u the max sharpness bend a specific coax will stand up to. Of course, cold flow applies to vy many other items. 73 Charles Harpole [EMAIL PROTECTED] From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Date: Thu, 22 May 2008 08:22:06 -0400 CC: elecraft@mailman.qth.net Subject: [Elecraft] KPA100 Tom, The reason for retightening the screws on the KPA Power Transistors is Elecraft uses plastic insulating heatsink pads.

[Elecraft] K3 popularity
I sent a msg to this reflector prior to the first K3 sold that it would become the IC-706 of the new age u had to be a post or a stone not to see that demand would be HUGE and immediate and long lasting. I think E could have sold 3,000 in the first month if shipping was upon immediate purchase. 73 Charles Harpole [EMAIL PROTECTED] From: [EMAIL PROTECTED] Subject: Re: [Elecraft] Elecraft Honchos!!! Date: Wed, 21 May 2008 14:05:34 -0700 CC: Elecraft@mailman.qth.net Folks, I am sure we all wish that supply at Elecraft was conveniently equal to demand. Order a K3 today, and have it by the end of the week or so. Clearly that isn't the case. I don't profess to know just how sophisticated Elecraft's market analysis is, but I'm relatively sure they aren't doing any exotic market surveys either. They are a small company with a big product! Also, I have no idea how they are evaluating just how much they can/will ramp up production. Doing so is expensive for one thing. It also adds greater complexity to the organization, particularly if that includes adding staff. I'm reasonably sure they don't want to increase staff only to reduce staff later. Some of that may be necessary, but it gets very sticky making those kinds of moves. Training new employees to get them up to an acceptable level of productivity, and then dropping them later, really hammers the bottom line. Personally, I would have expected the wait time to have decreased more than it has. But it hasn't gone down as much as I thought it would, and that suggests to me that K3 demand remains relatively strong--even 1 year later. I can only assume that it has surprised Wayne and Eric a bit too. Although all of us can fuss and complain about the wait time, it's really their product, and they are presumably doing what they think is right. Whether they are dealing with it correctly or not, it's their decision, not ours. So we just need to grin and bear it. That doesn't mean that allowing the wheel to squeek a bit won't encourage some positive response from them, but generally I think there will only be limited success in doing so. I think the best thing to do is to try and view all of this positively. By proceeding on a conservative path, Elecraft is hopefully minimizing screw-ups, not to mention protecting the company's viability. The longer they can sustain strong demand, the longer you have assurance that they will be around to help you keep their products running. Dealing with smaller companies can be somewhat risky. If they run out of demand, or ideas, or both, they tend to disappear. You don't have to think very long to come up with a bunch of names of companies like this who met an abrupt demise. If you don't like that suggestion, consider this one. I think the strong demand for the K3 would have easily enabled Elecraft to raise prices even more than they did. That would have probably have helped lower demand closer to supply, and they could later offer some blue light specials to prop up demand when it started waning. But they didn't do that--yet! So, even though I'm a bit frustrated about some things just like most of you are, I think I'll keep my complaints muzzled a bit. Besides, few if any of us have all the facts anyway. We have no idea what all the issues are that Elecraft is dealing with. We are all just a bunch of sidewalk superintendents, and what we think should be simple may well be just the opposite. In truth, I think a lot of our frustration is enhanced by the knowledge that the K3 is a great product with superior product support. We want it! Now! We don't want to go for the closest alternative. We just don't like dilemmas. Dave W7AQK ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] ending in K
If ur call ends in K, then just send KN always after ur call. Many, but sadly not all, know KN means go ahead you only but it gets the job done as per problem noted below. 73 Charles Harpole [EMAIL PROTECTED] From: [EMAIL PROTECTED] To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: [Elecraft] K3 Auto CW copy Date: Wed, 21 May 2008 11:39:57 -0700 CC: Elecraft@mailman.qth.net Hi All, I have only tried using he CW reading feature on my K3 a few times. Like most code readers, it misses a lot, and a little interference can throw it off track fairly easily. It takes a pretty good signal to minimize the errors. But I did check once by having it copy W1AW. There are two benefits to trying that. First, the CW is machine sent, so it's nearly perfect. Secondly, W1AW has such a good signal that interference issues are minimal. The reader did very well in that test. There were very few errors, and word separation was very good. I would strongly suggest that you check your K3 in the same manner to see if you are getting the word spacing problem. It was also interesting to watch my own sending. I've always thought my sending was reasonably good, and the reader did confirm that by showing the text I was sending in pretty much the correct text and spacing. But if I got the least bit casual about it, the reader reflected that as well. Spacing was the big issue, although most of my errors were exaggerated spaces rather than insufficient spacing. But I send with somewhat exaggerated spacing between words on purpose. I try to send words correctly spaced, and then leave a slightly extended space between words. I think this helps the receiving station clearly identify just what the word is I am sending. Every so often expresses appreciation for my doing it that way. In my view, I'm not sure there is a greater CW sin than running words and/or letters together. Interestingly, this process pointed out a glaring error that I have probably been making forever. That was in how I sent my call. I have a K on the end of my call, and I've always had problems in contest exchanges, etc. with the other station truncating my call to just a two letter suffix, presumably thinking my last letter K was asking them to transmit. It only takes a slight hesitation to cause the reader to reflect that. I kept seeing my call appear on the reader as W7AQ K rather than W7AQK. In thinking about it, it made me realize how easy it is to slip into these little bad habits. Some stations send their calls with insufficient spacing between letters. Things that we send repeatedly, like call, name, QTH, etc. seem to be common candidates for this type of error. It's as if, on occasion, we develop our own rhythm for sending these standard items in violation of the standard timing and spacing rules. And some folks just plain don't put the right number of dits in what they send. I heard one W6 station who repeatedly sent his call with 5 dits in the number 6, as well as repeatedly sending a 5 for an H. In cases like that, the reader won't lie! But your brain won't lie either. You will probably get that hey, wait a minute feeling about what you are hearing. Anyway, I then used the reader to retrain myself to send my call so that it did not insert an extra space between the Q and the K. It was a hard habit to break. Years of doing it wrong aren't easily erased. But I would strongly recommend that folks use the reader now and then to monitor their own sending. On a transmitted signal, the reader is very accurate in my view. And if you intend to utilize the K3's capability of translating your CW into RTTY, you better have your sending timing in good shape. Anyway, as I said above, the W1AW test is about the best way I know to really check out the reading capability of your K3. If it doesn't read that pretty well, I would guess you have a problem with your K3.

Making a computer copy CW of unknown speed must be difficult. But everyone knows my code is perfect :) I noticed the same thing when I was sending, but when I paid more attention to making sure my timing between words was consistent the spacing improved along with my sending ;o) What a nice tool for improving my sending! On the other hand I had a QSO with a near local (80 miles) and he had trouble copying me because of QRM. I was dialed down to 50 Hz and heard no other signal present. I opened up to 1 KHz

[Elecraft] love and choices
The discussion about which rig is best is ultimately funny. I remember guys who would almost fight anyone who would not acknowledge the idea that the early VW bugs were vastly superior to American iron (and I am sure more than several guys reading this are ready to pound out their support of their little friend VW) or any other discussions about issues that resolve mostly to matters of taste and love. One can read about great specs and that makes us feel good (or not), but virtually every ham lacks the skill, experience, and physical performance (ears) to actually hear the difference between high specs and the highest specs. And I am sure there are dozens of guys reading this who will swear they are in the tiny minority who ACTUALLY can hear the difference... skip telling me this; I already know what u r gonna say. I have already been around real audiophiles in the editing/mixing suites of movie studios who DO hear a lot. But, most people are not at this level. In my limited ability, I have only hrd one example of an obvious and real and discernable improvement in a rig was after I put the roofing filter into my Mark 5. That I could hear, but otherwise, nada. For those thinking of getting a new radio, I advise modestly for the choice be made based on one's likes, one's tastes, and the one that makes one feel better and the radio that invites especially you to love it. From this kind of choice comes satisfaction. Have fun. K3... VW bug ORION... Delorean or Edsel FT-2000... Toyota Camery FT-9000... Lexus IC-756Pro3... Audi TS-2000 Ford Fairlane IC-7800...

Jay Bromley and I visited with Larry Phipps at his booth for a while. Larry has several very innovative items that he sells, including probably the most unique wattmeter/SWR meter you can find anywhere (the LP-100A). What caught our attention was Larry's new panadapter for the K3. He's contemplating doing one for the K2 as well. Anyway, this new gadget (I hope I don't offend Larry by calling it a gadget) is very impressive. You should really go to his website to get the full details, but believe me, it is really a slick piece of engineering. I'm not fully familiar with the Icom bandscope on it's higher end rigs, but I think this product from Larry will rival or exceed what you find there. Additionally, it really constitutes a 2nd receiver, which opens up all sorts of possibilities. For example, maybe if you get this accessory you really don't get enough more with the Elecraft 2nd RX Can't really say that for sure, but it's pretty clear that Larry has something that might give one pause as to whether or not they need something over and above that. Anyway, the demo Larry gave us was most impressive. I suggest you keep one eye on his website for more details. In any event, the panadapter is fairly reasonable, and is available in either kit form or fully assembled. Larry says building it is not very difficult or time consuming. By all means, check all of this out. It appears to me that it would be a second receiver only with the aid of a PC, sound card and SDR software. What I would like to see is an external bandscope that does not require a computer. Either it would be completely self contained, or it would use an inexpensive portable LCD TV for its display.

RE: [Elecraft] Copyright images used on YouTube The Elecraft Band without permission
The status of copyright on open sites on the Web are a good question. The old (prior to Internet) rule was easy any work given away to the public lost its copyright protection. Example: a poet hands out copies of his poetry to public on a street corner. He loses his copyright then and there. I think the same applies to open sites where all the material is offered free to the public... that is, no payment back to the originator. The attachment of the C in a circle and the correct words of Copyright, name, and date, may provide some protection, but even then the excerpt taken must be substantial and not trivial (usually determined by shortness or length of excerpt). Citation of the original in short bits of the original likely also cover the possibly offending user. Basically, anything on the Web in open public sites can be used with very small danger of legal action against the copier-person. Further, the original owner must often prove MEASURABLE damages from the copying not easy in many cases.

RE: [Elecraft] Power pole for K3?
Notice to hams I have introduced a new DC power plug and socket for ham use It requires three special tools to strip the wire, twist it, and then crimp it into the connector (each tool is discounted at abt $100 each). The result requires soldering with silver solder, utilizing the Norcroft wicking tool (sold in 220VAC only), and the mating of the two halves with the preferred method of hay bailing wire (obtained from your neighbor farmer). Please note that it is possible to mate the two halves conviently so that reverse polarity is possible, as needed. These new connectors have the adoption of the National Amateur Radio Group and many manufacturers. It is recommended all hams immediately equip themselves with the proper tools for this great new fixture (not available outside of Utah). 73, Charles Harpole [EMAIL PROTECTED] From: [EMAIL PROTECTED] To: [EMAIL PROTECTED]; elecraft@mailman.qth.net Subject: Re: [Elecraft] Power pole for K3? Date: Sun, 20 Apr 2008 13:31:00 -0500 CC: OK, I'm late in throwing in my two cents. I have the Anderson Power Pole crimper and have used another also that is the correct size and has the proper jaws but it is not a ratcheting type. It is usable but is not as foolproof as the ratcheting type. The Anderson is the correct one and applies the proper force, and fits the sleeve and the wire size you are using. If you do not use this type, the wire will be loose or the connector deformed and will not fit or make a secure connection. What I am trying to say is that even IF you buy the Anderson crimper, you are likely to screw up a few of the first ones you try to crimp. Now you have to solder anyway or order some more connectors, not what you want when you are hot to get on the air. My suggestion, unless you have the proper tool and therefore are likely proficient at crimping, is to ORDER the wired set from Elecraft and save yourself the possible problems with first time crimps (OR SOLDER them in the first place). I will be making my own as I already have plenty stock of the all the parts and the proper tool and have made more than 100 connections so I do not feel intimidated by the process and the crimps that I get are very good electrically and physically. I still can't be sloppy about it as it is not hard to mess one up. 73, Jim - Original Message - From: Bill Maddock [EMAIL PROTECTED] To: elecraft@mailman.qth.net Sent: Friday, April 18, 2008 10:08 PM Subject: [Elecraft] Power pole for K3?

RE: [Elecraft] grounding radios
I have operated transceivers with no ground, with a poor ground, and a good one. I never could tell the difference in over 50 years of operating at scores of locations. I had RF lip burns on a mic grounded to a good ground, and I have had no RF problems at all on fourteenth floor with no ground ... even not on the electrical supply socket. Today, I have one ground rod and one ground run to the house electrical box WHICH IS FED BY ONLY TWO 230VAC WIRES. So far, so good. Lightning unplug everything and keep the ant/rotor wire entry point far away from ur radio. I had good success with a 1000 foot rhombic by putting the feed line end out on the grass when not in use 10 ft from house Was ok, but burned some grass around the end during a storm (grass was wet and green).

If your antenna system is at DC ground potential, such as a ground mounted vertical, again, be sure to unhook when not in use. If you follow some suggestions I've read on these groups, your rig will have a far better grounding system then the crummy 8' ground rod on your electrical entrance. Therefore when that big lightning surge comes along...Guess where it goes..It goes from every point in your house, right through your K3 to that super duper ground system you installed. Don't fall for it! Unhook the K3 and sleep easy. If you want to ground something, unhook your antenna and ground it. Don't let the feed line dangle in mid air. Hook it to that ground rod when your off the air. Let the lightning hit the antenna and melt it.

[Elecraft] OT-Noalox grease
As reported to me by W4YOK via a letter from the mfg, Ideal, who makes Noalox, the product that is used to mate dis-similar metals, is not actually a conductor. It does have vy small particles of metal in the grease but those can not really be counted on the conduct, sez mfg. Instead, it is made to retard water and to strip oxidation automatically off aluminum. Maybe that is why it works so well on the joints of yagis telescopic or swaged elements.

RE: [Elecraft] Alternatives to PowerPoles?
The major 13vdc ham radio equipment input power connector is the 4 pin Molex. This connector has proven in thousands of uses to be adequate to the voltage, the current, and the physical demands of this utilization. It is the de facto standard on K, I, and Y radios (for the vast majority) and the single only connector (other than the PL259-SO etc) that all three mfgs. amazingly agree on, making at least this matter so much easier for hams with different equipment mfgs.The four pins are often all used to increase the power handling capacity of the two-wire application. However, theMolex in all its pin configurations has a number of drawbacks -one time installation (unless the use of a special tool to retract the installed pins is used), i.e., not reusable,-lack of strain relief.-lack of positive attachment fixture (i.e., it could be accidentaly pulled out rather easily).Good points are resistance to crush (step on), can stand multiple plug in and out, is very well keyed and can take solder with care. It is reasonably available, but not in India, for example. It does not need glue. Formerly, some mfgs. used a two pin mic connector which likely had the power handling ok, took soldering well altho the pins are close together, and had both a great positive attachment (screw on) and a fairly good strain relief. Drawback was possible confusion of thisconnector with a mic.The Cinch Jones is a good alternative because it comes in many pin configurations, including two, is very well keyed, takes soldering very well, has a good strain relief, is vy reusable, is medium resistant to crush, can be pulled out too easily, is widely available (altho its uses are dropping, restricting its availability), The size of the two-pin version is nearly the same as the 4 pin Molex. The A Power Poles are the weakest of this line up of connectors and a very strange choice for ham radio applications.Charles [EMAIL PROTECTED]To: [EMAIL PROTECTED] Date: Mon, 7 Apr 2008 09:14:15 -0400 From: [EMAIL PROTECTED] Subject: Re: [Elecraft] Alternatives to PowerPoles?

Particularly given the desire for a genderless connector that can carry considerable current (20+ Amps)? Considering these are used for carrying polarized power signals, why do you want/require that they be genderless? Convenience and flexibility. There's a very good reason that wall outlets aren't hermaphroditic. That's because they are much higher voltage, and always a source. They're also meant to be used by people who know almost nothing about electricity. As radio amateurs, I'd hope we'd know a little about what we are doing. We use the same RF connectors (although gendered) for everything from the legal limit of power down to receiver inputs; make a mistake and the results can be very unpleasant. Is 12 volts somehow more dangerous? The only reasonable argument I've seen is that it allows charging batteries without adapters. But, given that improper charging of many modern battery technologies can be dangerous if a specialized charger isn't used, making it easy to connect a 13.4V, 20A regulated supply to a 12V lithium pack doesn't seem wise. The problem is that with adapters it's just as easy to make such mistakes. If you adopt gendered connectors, you'll get in the habit of having adapters everywhere, and there goes the advantage. . There's also the advantage of a universal standard - all cable ends the same; you never have the wrong end, multioutlet systems are all the same. --- And there's still the original question: what would you use instead? If there were a gendered PowerPole configuration, would that solve the problem? 73 de Jim, N2EY ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

The APP housings that I have purchased (from both PowerWerks and West Mountain Radio) have dovetail matings that need quite a bit of force to slide completely together, and I lock them with a drop of SuperGlue. I never had one come apart, and that includes the 3 of them that are in constant use on the workbench. The ones in the hamshack are more permanent - they are seldom changed. I have roll pins and use them only sometimes. If I use the roll pins, I lock the pins in place with a drop of Superglue. BTW - I just saw evidence that using the 'good' West Mountain crimper is not the entire answer. The crimps this gentleman had made with that tool had distorted the connector barrel and tongue severely such that good contact was not made. When we discussed the problem, I found that he was using the tool improperly. So even the proper tool can produce a bad job if you do not know what a good crimped connection looks like. Unfortunately, West Mountain Radio does not provide any instructions with the tool. 73, Don W3FPR Tom Hammond wrote: I must admit that I have had less than stellar results with the roll pins myself... having a number fall out over time.

I think I like the idea of filling the 'roll pin hole' with hot glue. That seems like a much more viable method. I currently use a short length of #12 solid copper wire, stuck thru the hole and then bent (on both ends) around at least two sides of each of the APP connector shells. This method allows for a slight amount of movement between the shells, but it does keep them together and in a manner which allows for complete disassembly if necessary at a later time. It's not terribly 'pretty', but it does work. 73, Tom Hammond N0SS ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

You fixed that with a good crimp tool. For those who solder the terminals the way to avoid getting solder on the contact is to hold the wire with the contacts upwards. A small vise or just propping the stripped wires up against a book or something works that holds the stripped ends steady pointing upwards works FB. Set each connector on the stripped wire with the contact UP, adjust the position so they are both aligned to slip into the shells easily, then apply heat to the metal terminal and feed solder through the holes near the terminal end until it flows around the inside and into the wire and connector *away* from the contacts. (I included that hint right on the instruction sheet.) It takes me perhaps 1 minute to attach two terminals to the stripped wires. Still, if I were doing a LOT of them I'd probably crimp them (with the expensive tool), especially if I were doing most of them in the field away from the bench. My point in posting to the thread was that it's not *necessary* to use a crimp tool nor does Elecraft recommend one do so over soldering. That's why the power cable kit assembly instructions say, Unless you have a high-quality crimping tool and experience using it, we strongly recommend you solder the terminals. Wayne and Eric added a suggested crimp tool to the connector assembly instructions for people who did not want to use a soldering iron regardless of the expense. Even so, it's important to know how to use the tool correctly. Ron ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

We did this to simulate the vibration of shipping via truck and aircraft. We then checked each unit for adjustment changes, etc. If they failed on the vibrator they were repaired and sent back to the vibrator for another run. We never had a unit come back due to bad soldering or loose nuts and bolts because the vibration burn in would find these troubles for us before we shipped. It's possible that tested K3 units are suffering from vibration during shipping which is revealing those anomalies that won't show up until after the units and kits are subjected to shipping vibration. You might be surprised how much vibration a cargo aircraft has during takeoff, landing and flight. Then there are the cross country trucks and local delivery trucks that have a lot more vibration in their cargo areas than an aircraft.

Date: Tue, 19 Feb 2008 20:44:34 -0800 -Original Message- Here is a solution from a very old QST,It's not from QST.and all I can say is it works for me. My shack is on the 2nd floor and I run several rigs w/ amps. I was having RF everywhere until I tried this: - Run coax ( RG-8 or similar) from rig to a real good ground . Put a.01 cap across the shield and center conductor at both ends. Cap needsto be 2KV or better. You will be using the center conductor as yourconnection to rig and the ground rod.You should also use an ATU asmentioned in an earlier reply. If it is not from QST, do you know where it is from? Do you know where (or how) I can get a reprint of it? My shack is on the second floor, too. And I believe that The Wireman used to sell a kit containing the capacitors! Dan Allen KB4ZVM K2 S/N 1757 - Those capacitors look like shorts at RF. So the center conductor is tied to the shield at RF, but not at D-C. Direct current isn't the problem. Tying the shield to the center makes the impedance of the cable slightly less because it's slightly bigger to the RF. Even so, at RF it's still just a wire from the second story to ground. If you force a wire to either a low impedance (grounded) or high impedance (insulated) at one end, it will show at the opposite end the opposite impedance if it's 1/4 wavelength long or an odd multiple of 1/4 wavelength long, and it'll show at the opposite end the *same* impedance if it's 1/2 wave long or a multiple of 1/2 wavelength long. Everything in between will be something in between. Even a marginal RF ground will cure problems caused by no RF ground in some situations. Even a hunk of coax. The things you can do to provide a low(er) impedance ground than a wire is to make the wire larger, or parallel a lot of wires to ground, all separated, such as running a large wide sheet of metal from the rig to the ground. If you're on the second floor, that's seldom practical for those who live in the same building with our shacks ;-) My shack is, fortunately, on the ground floor about 3 feet from where the large metal conduit for the underground utilities emerges from the earth. It's also where all the other services - telephone, cable, etc. - are grounded along with the mains ground. And my RF ground goes there. Since it's only a few feet away, I use a 2-foot wide strip of copper attached to the wall from the rig to a point on the wall opposite the mains conduit. Then a pair of ground wires makes the run through the wall to the mains conduit. Each wire is about 12 inches long. Two in parallel reduce the impedance of one. To RF, they look like on FAT conductor. I didn't suggest that because, from the 2nd floor, it'd take very large piece of metal to show low enough impedance. But all is not lost. You can operate free from RF when you aren't close to ground. It's been done by everything from rigs in Zeppelins to Hams stuck in the attic! The trick is to keep the impedance of all RF antenna circuits at the rig low. A 50 ohm dummy load does that, but it's a lousy radiator. But it demonstrates the concept: keep the impedance low. Feeding an antenna at a current loop (low-impedance) point will do that. That's why Hams seldom have trouble with center-fed dipoles. The impedance at the center of a dipole is low - typically not far from 50 ohms. Bringing the feed point of the dipole directly to the rig or through a length of coax that has a low SWR keeps the impedance at the rig low. The impedance is low because each half of a dipole is 1/4 wavelength long. The far ends are insulated, forcing their impedance high. So the ends at the rig are low impedance - typically 20 to 30 ohms. Two of them makes a 50 ohm load for the rig. The famous Zeppelin antennas did the same for a rig floating high in the sky held aloft by a bag of hydrogen. An open wire feed line, exactly 1/4 wavelength long, was connected to the rig. At the far end one side of the feeder was connected to nothing at all: it was well insulated. The other side of the feeder was connected to a 1/2 wavelength hunk of wire floating out behind the ship in the air stream. The 1/2 wavelength long wire showed a high impedance to the feeder at its

The basic radio, as well as the subreceiver, has a full array of ham-band-only filters at the front end. This is to ensure excellent performance in the ham bands. These filters are switched in by means of relays. The KBPF3 option is a small plug-in module that sits above the ham-band filters. It, too, has a number of filters switched in by relays. The difference is that these are wider filters, covering all of the area between the ham bands. But they share the same input/output path as the ham-band filters. When not selected, the GC filters have absolutely no effect on performance, thanks to a very careful layout that minimizes trace lengths. When you tune the radio well outside the ham bands, an appropriate GC filter is automatically selected by firmware. Hopes this helps -- at least with your KBPF3 question.

Remember that it's only mysterious until you've actually wound your first toroid. After that, it's all mostly downhill (with the wind at your back, usually)! Remember that you're going to get a (typically) excellent manual from Elecraft that goes out of its way to show you pictures and give lots of good advice when you need it--at the moment you're winding the first toroid. I've done lots and lots of toroids, and I still was impressed with the graphics, winding instructions and lead dressing advice that's in the manual. So, don't be afraid to try--they're really not hard at all, just new to someone that's never done one before. In fact, one could say that they're no harder than winding any inductor, and in some ways quite a bit easier. If you try your first one, and you're still not sure if it's right, take a quickie digital picture of your finished toroid, and email it to either Elecraft's great tech support folks or here on the reflector (just don't send big attachements if you can avoid it). Then ask, Hey, how does this one look? Guaranteed you'll have lots of seasoned eyes looking over your shoulder. Don't be afraid to try. Oh, and did I forget to mention that I ordered my recent K2 toroid set from Mychael, the coil guy!?

But make sure you double check the number of turns. Being off by only 1 turn may not sound bad, but in many cases it represents a big increase in inductance, possibly over 10%. As others have said, just count the number of times the wire passes through the center of the toroid. I've easily wound well over 100 toroids in the past few years and have never had a problem with winding them. Be especially careful stripping the wire before soldering it into the circuit. You can search the archives for various techniques. One thing I do in that regard is insert the part BEFORE stripping the wire, to check for proper fit. Then I trim it, leaving maybe 1/8 extra on each lead. Finally I remove it and concentrate on stripping the wire where I know it's going to be contacting the solder pad. If you don't trim it first, you'll end up spending lots of time stripping parts of the wire that will either be snipped off after soldering or will be nowhere near the solder pad. 73's and good luck, John AA0VE [EMAIL PROTECTED] wrote: I just ordered a K1 four band transceiver.

BW 1.9 and 1.60 settings. -Auto SPOT seems not to work every time (may be operator error)... Same is true with CW or RTTY decoding read-out. Brags: -VOX on ssb is really super, best I have ever used and best I can imagine. -AGC is vy nice except for pops in #1 above. -CW speed and RF power read-out on the dial... nice. -Delta f amber light is nice reminder. -The ATU is lightning fast amazing. -Main knob feel is a delight and tuning rates (selectable) are perfect.

There was a time ... still somewhat with us... when the 6 pin Molex was the power connector of choice and AMAZINGLY K, I, Y, and others HAD THE SAME PIN OUT on these. The telephone style plug now arriving on so many rigs answers the manufacturers' dream because they are so difficult to self-install that the customer is nearly forced to purchase specific mics ... THEIR LINE. Too,There was a time when a ham would have sneered at a DIN plug, that nightmare--both to solder to and to cope with differences.So on and on. The use of different pin-outs is cause for consumer anger because the choice is not based on good engineering practice but on the desire to sell their own differentiated product to those who have also purchased their line of products. Because most of the K, I, and Y crop of mics are so equally bad, the only way to make their product different is not via quality but via a unique pin-out plug. Shameful business practice that only hurts the consumer. The reason Bob Heil's mics sell is that THEY ARE BETTER, and he has made an easy line of adapters, too. Elecraft made a good showing by trying to copy the Kenwood standard even if there is a problem with SOME CASES with pins 5 and 6 reversed. That I have the time to explain the obvious shows that I am retired, and fill in the blank. 73,Charles [EMAIL PROTECTED] On Wed, 13 Feb 2008 08:23:07 +, Ian J Maude wrote: I cannot keep quiet any longer! :) What is all the noise about microphone compatibility? We are radio amateurs, it should be simple enough to wire a microphone for a rig. Just look at the pin outs on the mic and the rig and wire accordingly. The circuitry is not exactly complex! If we buy *any* radio we pretty much know that the mic wiring is going to be different. 4-way, 8-way, RJ45 connectors, the list goes on. What ever the manufacturer decides is the right way for them, this has always been the case. It really is quite simple. Is your microphone a dynamic type? If so, wire it for Kenwood and it will work. Does it need a voltage? Look at the diagrams as I mentioned before. Good grief! Elecraft are building the rigs for us now and we are still moaning! ;) 73 Ian ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] mics
Ron about the time when the famous D-104 was in every shack with a vy wide and rather flat response... Astatic also sold a10-C (ceramic) and the 10-D (dynamic) elements/mics that were shaped for voice with a peak in the mid VOICE range. I still have my 10-C and the Astatic paper showing its response curve. Altho much loved, the lolypop D-104 is notoriously broad and flat and is not much good as a communications mic. To enlarge ur info on mics, please consult Bob Heil's info on his mics that are real communications mics. The MC-50 generation of mics were not so good. 73, Charles [EMAIL PROTECTED] From: [EMAIL PROTECTED] To: elecraft@mailman.qth.net Subject: RE: [Elecraft] electronic product standards Date: Wed, 13 Feb 2008 12:12:55 -0800 Bill, NY9H wrote: a $1.59 electret mic element from radio shack works GREAT with all my icoms and my K2s and K3. --- Yes, those Radio Shack electret elements are excellent. I have one mounted in an scavenged hand-held mic housing that works FB. The element has a very wide frequency response, since it's designed for general purpose audio work, but that's not a problem with modern rigs with filters such as the K2 or K3. Back in the old days of vacuum tube A.M. rigs, the modulators tended to broad as a barn, passing all audio put into them with only minimal shaping provided by the values used for coupling and bypass capacitors in the speech amplifier stages. There were some microphones produced for the communications market back then such as the famous Astatic D-104 which had a microphone element with a shaped response showing a distinct hump around 3 kHz, rolling off slowly at lower frequencies and somewhat faster at higher frequencies. That hump helped with articulation by emphasizing the mid-range speech frequencies. Astatic even published a frequency response chart showing exactly what it looked like, but back in those days most microphone element manufacturers provided frequency response charts with their various mics. I don't know if anyone is doing that today for mainstream communications microphones. Even the high end Ham mics only offer general and uninformative comments about shaping and clarity that say much and convey little. Interestingly, one of the big exceptions is the inexpensive little Radio Shack electret element. It comes with a frequency response chart showing a very flat response across the audio spectrum. But all is not lost: the SSB filters in modern rigs prevent excessive audio band passes and the K3 goes farther yet, offering a transmit equalizer with which one can shape the audio response to suit one's voice. When doing that, it's good to start with a wide range flat microphone element response like the Radio Shack electret. I rather expect, although they don't say as far as I can see, the high end Ham mic manufacturers are using elements with a flat response and perhaps doing some sort of shaping in design of the enclosure. If so, then choosing a Ham mic today is really a matter of cosmetics: choosing what looks nice. Another list member here asked what, exactly, is the best response to provide the best intelligibility under all conditions and how can that be seen unambiguously on a display like spectrogram? That's a good question. Sometimes we get too many choices. I'm happy to record my rig using a wide-band auxiliary receiver and adjust the equalizer for a sound that I'd like to hear from the other end in a rag chew. But then I don't spend long hours yelling into the mic in a contest or trying to shout down the others in a DX pileup ;-) Ron AC7AC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] At last, knowledge!
At last, after ignorant flames, comes W3FPR's knowledgable statement about the now-famous pins 5 and 6. Thank you, Don, for showing the facts, not the flames. 73,Charles [EMAIL PROTECTED] Date: Wed, 13 Feb 2008 09:55:12 -0500 From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: Re: [Elecraft] RE: Elecraft Digest, Vol 46, Issue 21 CC: elecraft@mailman.qth.net Jim, Eric has already provided the answer that the Elecraft microphone pinout is compatible with Kenwood dynamic mics. Those Kenwood wired mics that have an internal preamp will likely *not* work. I do not have any information about your particular cables, but... One must know the connection information for any particular microphone or cable that you intend to use - I need to be certain that the transceiver will not destroy the microphone nor will the microphone damage the transceiver - one should not pick up just any old mic and plug it in without checking first. If you have a Kenwood mic, all that is necessary is to check for a connection at the mic plug pins 5 and 6 - if there is *no* connection to these pins, it should work with the K3. The K3 is Kenwood *compatible*, but not Kenwood *identical*. G4WPW has compiled a lot of good information about many, many microphones which can be found at http://www.qsl.net/g4wpw/date.html, or use Google and other search engines to seek the information you need. We here on this reflector have information related to the Elecraft equipment, but there are so many microphones out there with different characteristics that it is unreasonable to expect that we here on this reflector will be able to provide accurate information about any particular microphone (unless you are asking us to do the research for you - and that is just not reasonable IMHO). 73, Don W3FPR WS6X wrote: -- Original Message: 35 Date: Tue, 12 Feb 2008 22:18:14 + From: Charles Harpole [EMAIL PROTECTED] Subject: [Elecraft] #309 first issues-Front mic socket not compatible with any other mfg. that I can find.

[Elecraft] #309 first issues
I got #309, factory built, into service. First contact was VP6DX barefoot. First impressions (citing problems only): -AGC does not clamp down on short duration pops/tones/blasts of toned noise. -Stepping thru all 5 filters is a pain when u just want to compare F1 to F2. -Front mic socket not compatible with any other mfg. that I can find. -sending C in cw is weird, using the internal keyer, throws my timing off. -BCI blows in as bad or worse as my IC-775dsp. So far, this appears cured with ICE BCI filter in line, but this is my big disappointment. As of my first week with my K3, if my opinion does not change over usage and time, I will not keep it and will go for the TV display of the FT-2000/9000 line of radios which also have the hi-Q extra filters (which may or may not deal with my huge BCI incursion). 73, Charles [EMAIL PROTECTED] ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 in the marketplace
Rick, I too want to watch Elecraft evolution as a company. Niche marketing is especially interesting to me. I know it is a personal factor, but I want a separate mode switch, and separate instant selection band switches. Leaving these off a high end rig has no excuse and altho die hard Elecraft folks will defend to the death, these two human factors are important and I am hearing privately from many guys who agree with me and who like big rigs (but will not send a message to the group, likely for fear of attacks from rabid fans). See, I do not want a rig that I have to get used to. Also, because the rig was designed from scratch, there is no excuse for the small box/front panel. And for TWO fans! That is the main reason I say K3 evolved from K2... i.e., toy sized, etc., but not the innards, of course. This reminds me of the Drake TR-7 face design which was a HUGE mistake altho Drake told me that they consulted lots of experts (ex-spurts) and then came up with a look of a consumer stereo. I know that hurt that rig market when it was up against JA rigs with military look. Real engineers seem to stall out when they try to confront intangible human factors, which is understandable because those factors often do not make logical sense. 73, Charles Harpole [EMAIL PROTECTED] _ Test your celebrity IQ.

[Elecraft] K3 in the marketplace
Elecraft designers had K2-its thinking they were mostly evolving a K2 Big mistake as I said in an earler message The K3 has jumped Elecraft into the areana of the ORION 2, FT-9000 and IC-7800 and great specs are great, but the human factor... so often ignored by purist engineers... is left out. This means they can still be beaten in the marketplace when their specs indicate they should be the only hi end rig of choice. If I can afford it, I plan to give myself an ORION 2 for Xmas, just after taking delivery of my K3, I hope. I know I can sell either here in Thailand due to the buzz on both, so maybe eventually I will take my pick and if I can not hear the difference between the two (likely due to my weak abilities in that area), guess which will go up for sale.. 73, Charles Harpole HS0ZCW [EMAIL PROTECTED] _ Kick back and relax with hot games and cool activities at the Messenger Café. http://www.cafemessenger.com?ocid=TXT_TAGHM_SeptHMtagline1 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
