Re: [Elecraft] K3 and WSPR - configuration?
I run WSPR on 500-KHz as WD2XSH/45. I interfaced the computer audio thru the K3 line-in and line-out jacks and control PTT with the RS-232 connection. This requires you to run DATA-A. I set my receive audio with the computer audio mixer window without any changes to the K3. It runs at about -1 to -2 dB. For transmit level use your ALC meter and adjust the computer audio mixer (wave output) level for about 5-6 on ALC (press the TEST button on WSPR window for setting up Tx levels). Read the WSPR instruction manual for operating hints. Use spots to unlink your reception reports so others can view what you see. That's it. These same set ups will enable running any of the programs under WSJT. JT2 and JT4 have been used for making digital contacts on HF. JT-65 is used primarily for eme. FSK441 and JT6m for meteor scatter (think 6m). On 500-KHz I run 4.15w ERP (100w to the antenna) and have been detected at 1366 miles. 500-KHz WSPR is spanning the Atlantic.

Re: [Elecraft] Another GREAT example of Elecraft care for customers...
I'm sold- after I installed the KSYN stiffeners before my upcoming trip to ZK2 and VK9, my radio didn't put out any power. Gary gave me a bit of information that was pointed in the right direction, but didn't take care of the problem, so I got a return authorization and then hand carried it to Watsonville on Monday. Today, I got a call telling me that the problem was a crushed SMT cap on a KSYN board, it was all fixed and checked out, and it'll be sent out tomorrow. I expect it on Monday, since even regular UPS, Watsonville to here, is essentially overnight. Fast service and a PHONE CALL telling me what was wrong BTW, this is the first change that's been a problem (and I usually do the SMT change)- I must have been clumsy with the board, somehow. 73, doug __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] Roofing Filter Usage
With respect Ron, as far as I know the term Roofing Filter was in use many years before up-conversion superhet receivers with a fist IF at VHF started to appear in the market. It was at least fifty years ago when I first ran across the term, which was used to describe the first IF filter used in a voice/data multichannel Independent Sideband down conversion superhet receiver manufactured by our company at the time. In this particular case the bandwidth of this Roofing Filter was wide enough to allow both the upper and lower sidebands of the incoming signal to pass, and further downstream in the IF two filters described as USB and LSB IF filters were used to separate the signal's sidebands for further processing. It could be argued that the input bandpass filters of a receiver act as Roofing Filters, and that all filters which follow should be described as IF filters, Audio filters or whatever. However the applicable rules of terminology as I have understood them since those ancient times restricts the use of the term Roofing Filter to the first IF Filter, but the term should only be used if a second and narrower *IF* filter follows the first ( which would include DSP filters, but only if working at IF not audio). The use of relatively wide bandwidth Roofing Filters at VHF in up-conversion receivers is actually not such a problem that it might appear to be, because the use of a very narrow filter behind the mixer can be counter productive in terms of close in dynamic range, especially if the filter is followed by a well designed decent IF. The same is true of down-conversion. LO phase noise is a problem when up-converting to VHF. 73, Geoff GM4ESD On Friday, October 29, 2010, at 03:04 +0100, Ron D'Eau Claire wrote: The term roofing filter came into use when receiver designers started up-converting to a first I.F. in the VHF range. There are no practical narrow filters at those frequencies but it was necessary to filter out mixing products far from the desired frequency, so very wide (several kHz wide) filters were used to define the general range to be further processed. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

[Elecraft] APF in 4.16/2.63 works well!
Wayne released APF to Field Test last night and also said it was OK to post comments. It seems to work very well and I expect it will be released publicly soon. APF (as implemented in the FT-1000) has always been a weak signal receiving tool. It's not for adjusting PITCH or some of the other ideas discussed. Last night I happened to be listening on 160m around 02z just after I got it installed. 5R8RJ usually comes on 1826.44 a little before his sunrise. Conditions were very poor but he was spotted by a UA4 around 0210z. I could hear nothing of him on his normal frequency. CW Skimmer's waterfall was also showing absolutely no signal there...not even a faint trace. I then actuated APF and could then copy him about Q3 in the noise. This is exactly what APF is designed for...pulling extremely weak signals out of noise...and it does it very well. The user interface is also very simple. Although it may change slightly before public release, you hold DUAL PB (as though you were going into the previous CW focus mode) and then adjust SHIFT in 10 Hz steps to peak the signal (independent of your PITCH setting). It works well in diversity also. Nice job guys...all the previous FT-1000 owners will rejoice! 73, Bill W4ZV -- View this message in context: http://elecraft.365791.n2.nabble.com/APF-in-4-16-2-63-works-well-tp5686011p5686011.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] KX-2 wish list
I agree a zillion percent with Stan. The KX1 is a phenomenal radio, with a sensitive receiver and solid transmitter. I typically operate using a 12v battery and a Buddipole, and making contacts is never a problem. They're also a load of fun to build! Steve, KW4H On Thu, Oct 28, 2010 at 3:19 PM, stan levandowski sjl...@optonline.netwrote: ..so there I am, in the garage, late afternoon two days ago, with the newly homebrewed 20M mag loop sitting in an umbrella stand about 18 inches off the concrete floor. It was threatening to rain and I didn't want to put it outside. Pretuned the loop with my antenna analyzer for the low end of 20M. Now I need something to transmit with. Quickrun upstairs, grab the KX1 and a headset and run back down to the garage! There were 8 fresh AA batteries in the KX1 with 1.4 watts going out according to the KX1 display. 20M sounds open and pretty hot! Let's try. Standing in the garage, a few feet from the loop, with the KX1 in my left hand, I worked Illinois, Indiana, Guayama, P.R., and St. Petersburg, Russia (UA1CE) from here in NY. ..and if the band wasn't open then I doubt that even a hundred watts would have been enough power. With QRP, timing is everything, in my opinion and experience. Just my opinion, of course, but there are two radios that Elecraft should never mess with - the K2 that launched them and the KX1 which is the premier QRP ultra-portable. For those who may not be familiar with it, there is a SDR in Atlanta, GA - WB4MAK ( http://www.websdr.org/ ). Log on and tune the SDR to your transmitting frequency, plug a recorder into your computer's earphone jack, and record yourself calling CQ at 15 or 20 watts. Then do it at 10 watts; then at 5 watts, etc. You'll certainly notice a difference in signal strength but you might be surprised at how little that difference is. The KX1 - in my opinion - has just the right amount of compromise between form and feature. If the KX1 were enhanced to higher power, a more powerful and longer lasting power source, and a few extra options such as noise blanker and upgraded filtering...then it would approximate the K2 which already has 15 watts, options galore, and a hefty battery alternative. It seems like it would be a pretty weak business case to insert a product between the barebones KX1 and a barefoot K2. At least that's my opinion.

Re: [Elecraft] Roofing Filter Usage
Bill and group - Can't say it was first, but has to be the first US designed and produced ham rigs to use up conversion. The DRAKE TR-7 has no RF Amplifier and uses a diode ring up converter to 43 mhz as the first IF. The design was in the late 60s, early 70s. Bob Drake and his company have always been know for innovative design. In those days the term Roofing Filter hadn't be coined by the marketing types and the TR-7 has only one fixed filter at the high IF.

Re: [Elecraft] KX-2 wish list
At first, I passed over this thread. But then I remembered a couple of changes I would like to see in my KX-1 I use my KX-1 for portable operation when we go camping, hiking, or sometimes in a local park or forest preserve. I have never used the KX-1 for anything other than CW QSO's, ie no SWL'ing. So the improvement I would like to see is to have a fixed bandwidth (500Hz) 4-pole crystal filter in the IF. When the band is active, and especially during sprints, that extra pole of filtering would be a big plus. That's it... a small change (maybe 3 additional parts for the additional pole of filtering, and remove a few parts since it's now a fixed bandwidth) for a big improvement in performance. This would seem like a pretty simple mod, and it's on my list of projects - just haven't gotten to it yet. (If anyone has already done this, I'd really like to hear from you.) 73, ed - k9ew __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] APF in 4.16/2.63 works well!
I agree with Bill. I've had a chance to preview the APF function and it seems to operate very well although I haven't seen a any really weak stations like 5R8RJ on 160. APF as implemented by Lyle may become an alternative to a very narrow (e.g. 250 or 200 Hz) CW filter for casual operators as it provides a spotlight selectivity but does not provide the same level of IF protection as the tighter first IF filter. The one reservation I have is the potential need to use the menu system to select between the original Dual PB filter and APF. I would much prefer to see a two level hold - normal (500 ms) hold for Dual PB and long (1 sec) hold for APF like Link and Diversity with the KRX3 - for selecting Dual PB or APF. There are a few other control items and questions about use with the programmer's interface to be resolved but it looks like the capability is well on its way to a wider public beta. 73, ...

Re: [Elecraft] Roofing Filter Usage

The Japanese manufacturers got the idea that everyone wanted general coverage in their receivers, which then required up-conversion and an IF at VHF.

On 10/29/2010 3:33 AM, Pete Smith wrote: I am currently setting compression at 22, You do NOT set compression by looking at that number. Rather, you set compression by ADJUSTING the compression control until the METER indicates the desired amount of compression on speech peaks. A good setting for contesting and DXing is about 10 dB. If you're getting reports that your audio is thin, that's an EQ issue, not a compression issue. BUT -- the best way to evaluate EQ is to have the other station listen with their RX set to a wide IF bandwidth. For contesting, we generally WANT our audio to be at least a bit thin -- we don't want to waste TX power on the lower octaves, which don't contribute to intelligibility. I just went through those adjustments yesterday with N6GQ, who was setting up his K3 for a single-op at YN4AA for CQWW SSB this weekend. I listened to him, and he did the same for me. He started out with the FOUR lowest bands at maximum cut, and it sounded too thin. We brought the fourth band up to zero, and it wasn't quite enough bass cut, but it sounded right on his voice with about 6dB of cut on that band. This was with my IF set wide. Then I narrowed my IF to 1.8 kHz, and he sounded thin. He SHOULD sound thin to a station using a 1.8 kHz filter, so we left it there. My voice sounded best to him with the three lowest bands at max cut, and the fourth band set to zero (flat). Hope this helps. 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

I've tested the setup extensively and everything runs pretty smooth except: randomly in the middle of a transmission PTT will simply freeze and the only way out is to switch the K3 off. Switching it back on and wait a few seconds will unlock the frozen N1MM-MMTTY software and operation resumes normally. Sometimes though I have to shut down N1MM and restart fresh. Now the second thing that happens (not as often) is a PTT freeze followed by computer shutdown and bluescreen error message before automatic reboot. I run SO2R setup with other radio being a 756 pro2 and Rigblaster plus. This never happened on this setup. As a matter of fact, whenever the freeze takes place, the second radio and its N1MM-MMTTY software are still running and not affected in any way. I've looked into all kinds of possible rfi issues to no avail. This may happen 3 or 4 times during a contest.

Re: [Elecraft] APF in 4.16/2.63 works well!
APF has a very significant improvement on weak signals in the noise. I completely agree with prior posters. HOWEVER... I would like to be able to ***VARY THE Q*** with the width control and LEAVE IT ON with a mild Q, and sharpen it as required. If I can back it out to 2 dB with a width function I would probably leave that on all the time and grind in as needed. I already do that with Width in weak cases that are on frequency. ONLY when APF is on could we have the WIDTH tap toggle between APF Q displaying APF Q=3 in lower display and between Roofing/DSP bandwidth displaying BW 0.40??? You could do the same thing with SHIFT to go back and forth between adjusting Roofing/DSP SHIFT displaying FC *0.45 and APF *0.45.Using WIDTH to control Q is intuitive. When APF is in there is no moderate setting, it takes over the passband and makes copy of a signal up band difficult. It will require repeated use of DUAL PB to go in and out for weak signals and back out for normal use. Use of a HOLD function as a frequent change is a problem. In trying to get used to the HOLD on DUAL PB to go in and out of APF to hear in the rest of the channel, I repeatedly hit NTCH instead. HOLD's are only good for settings that persist for a while during operation. E.g. I don't need APF ONLY as a better substitute for 50 Hz. I need it to work ALSO as a milder center emphasis inside the 400 Hz roofer, and be able to twist a knob somewhere to move between mild and sharp. Even with what appears to be only a 2 dB peaking around 450, the MP was improved inside its excellent dual INRAD 400 selectivity. If this is not done, it will be very difficult to use it well in a contest. No easy-to-use variable Q is a deal-breaker for me. In the end for contests it will cost Q's and will have to tell people to leave it off, just like NR. Only turn it on for a really weak one if you can remember how, and then turn it right back off. Then when I get home chasing weak DX I'll turn it all back on again, and work some stuff I couldn't hear before. 73, Guy.

[Elecraft] KX-1 (sic) wish list
Why not just use an outboard amp. when you feel you need more power? The need more power approach to portable QRP operation is nonsense. What is needed for QRP operation is a DECENT antenna. Not an expensive antenna, just a decent antenna. Something like a resonant dipole that can be built for less than $10, weighs almost nothing, and can be packed in almost no space for storage. That 25 to 85 foot of random wire is easy to string out, but problematic to match with the KX1's very very limited ATU, and even if matched is a terrible radiator. Even worse are those $300 (or more) commercial vertical antennas. Some apparently feel that more money spent means more performance. The opposite is true. I've played around with backpacking antennas and QRP for more than 30 years. It's my **principal** interest in ham radio. Here's what I've learned about portable temporary-site HF operation: There is NOTHING that will beat a cheap resonant dipole, even one at low elevation. In the many side-by-side tests I've done from campsites comparing a very expensive commercial vertical to a home-made dipole, typically greater than a 30 db (5 S-units!) difference will be observed between the two on both receive and transmit. Even QST's evaluation of one of the most expensive and elaborate portable verticals, the Outbacker Outreach with Outpost (a very ineffective tripod base that magically couples the vertical to ground...$700 total) showed similar magnitudes of performance differential. This means that my 5 watts into a dipole trumps your 5000 watts (!!) going into your high-dollar and heavier vertical. Plus, you've still got poor signal reception due to your antenna. Random wire radiators are generally comparable to verticals. Antennas of these types only prove that at times contacts can be made no matter how poor your antenna is. If a site is so temporary that the 33 feet of a 20m dipole can't be strung out, then why even bother unless one enjoys frustration at not being heard, and at not hearing much. Now as far as what I'd like to see in a KX2: 1. Re-design it all so that the kludgy and tricky add-on circuits for 80 through 20 meter coverage are on one PCB with the rest of the KX circuit. Put the ATU on that circuit too, and make it have matching capability closer to that of the K1. 2. Re-design the case eliminating any space wasted by a provision for internal batteries. Internal batteries in a small QRP rig is NOT a good idea, especially since an external pack (perhaps one designed for the KX2) can be so small and much easier to recharge. 3. Have a 4-pole crystal filter. 4. Use a DDS chip that can support 15 meter operation, and add that and 17 meters. 15 meters is one of the very best QRP bands when it is open. I would consider a KXx with these added features to be almost perfect. 73, Mike / KK5F __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] Roofing Filter Usage
Thanks for the clarification Geoff. The fellow with the original question asked what why he was still hearing QRM even when using the 1.8 kHz crystal filter (presumably listening to SSB) and David responded, The purpose of the roofing filter is...not to provide selectivity. I was respectfully disagreeing with David when speaking of the K3. In the K3 the first I.F. filter (what some call the roofing filter) provides the main selectivity. That's why a variety of bandwidths are provided for various modes and why so much attention was paid to the design of those filters to provide excellent stop band attenuation. The DSP filter at the 2nd I.F. provides additional filtering but it's the first I.F. filter in the K3 that is responsible for providing the bulk of the selectivity. Personally, I don't use the term roofing filter for such a filter. Rather when I see roofing filter I think of a filter such as David described that cleans up unwanted mixer products so that the final selectivity can be taken later in the signal path. That's how I've always seen roofing filter used in the commercial equipment I've worked with. IIRC the term roofing filter didn't come up with respect to the K3 until after it was introduced and Hams were trying to compare its architecture with Ham rigs that up-convert to VHF for the first I.F. Wayne answered many questions here on the reflector and finally wrote the paper on the web site explaining it further. He has added roofing filter in parenthesis in places in the Owner's manual to help those Hams understand the K3 Crystal Filter selected is the first I.F. filter. However, it's clear that applying the name to the K3 skews the definition of roofing filter from what Dave and I have always known in the past. Ron AC7AC -Original Message- With respect Ron, as far as I know the term Roofing Filter was in use many years before up-conversion superhet receivers with a fist IF at VHF started to appear in the market. It was at least fifty years ago when I first ran across the term, which was used to describe the first IF filter used in a voice/data multichannel Independent Sideband down conversion superhet receiver manufactured by our company at the time. In this particular case the bandwidth of this Roofing Filter was wide enough to allow both the upper and lower sidebands of the incoming signal to pass, and further downstream in the IF two filters described as USB and LSB IF filters were used to separate the signal's sidebands for further processing. It could be argued that the input bandpass filters of a receiver act as Roofing Filters, and that all filters which follow should be described as IF filters, Audio filters or whatever. However the applicable rules of terminology as I have understood them since those ancient times restricts the use of the term Roofing Filter to the first IF Filter, but the term should only be used if a second and narrower *IF* filter follows the first ( which would include DSP filters, but only if working at IF not audio). The use of relatively wide bandwidth Roofing Filters at VHF in up-conversion receivers is actually not such a problem that it might appear to be, because the use of a very narrow filter behind the mixer can be counter productive in terms of close in dynamic range, especially if the filter is followed by a well designed decent IF. The same is true of down-conversion. LO phase noise is a problem when up-converting to VHF. 73, Geoff GM4ESD __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

[Elecraft] KX-2 wish list
KK5F: I too have been using wire dipoles as well as verticals and more or less sloping wires. I totally agree that the dipoles (actually inverted vees in my case) are superior over the rocky soil around here, but I don't see a 30 dB difference; more like 6 to 12 dB (no rigorous measurement done). To me, the portable hf rig is safety equipment for hiking, and the technology faces tough comparisons with cell phones and fm handies/repeaters. With solar flares being an extreme case, there is a wide range of bad hf conditions that fights our ability to make a contact. Antennas always deserve more attention, but more power would certainly also help the scoring average, even if the increase is only 1 dB. Better receive filtering would help a lot too, as would coverage of the higher bands. 73, Erik K7TV __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] APF in 4.16/2.63 works well!
The design goal was to duplicate the FT-1000D APF. The FT-1000D has no variable Q function. What you are proposing is completely different than the design parameters ... you want an Autek QF1 not the FT-1000D APF. I agree with Joe on this. The bandwidth of a CW transmission is narrow and does not change.(*) I think pursuing variable Q would amount to diminishing returns over fixed Q and adds an unnecessary variable. I also like the use of the context filtering - a feature not found in the original FT-1000/D circuit. As Joe suggests, an Autek QF1A can be used if one really wants extreme APF flexibility, or a single-channel parametric EQ may be a better way to go since a PEQ allows the user to alter gain, Q, and frequency. Either way, those devices can be easily inserted into the K3's audio path. Paul, W9AC (*) CW bandwidth does change with speed but at normal CW keying rates, bandwidth is largely a function of only the waveform slope. At high switching speeds, bandwidth becomes relevant as a function of both waveform slope and keying speed. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Kudos super job, Im sure there will be small amount of tweaking here and there etc, but this is great. Bill has testified to what is probably the greatest use for APF, pulling weak signals out of the noise ( and I mean weak), it will not make 100 percent copy of them, but sure will allow for a QSO that was impossible before. This brings to K3 to the best there is in my book. Thanks thanks thanks Wayne and Lyle for listening to users who want the best performance for not only our personal use but for the K3 in general. I think Waynes comments on his and Lyles surprise as to APF effectiveness is the icing on the cake. Also please do not do as Yaesu did in its mistakes, they listened to people who thought it was too ringy and reduced the Q it made the FT-1000D later series worthless and they had to be modified to the old circuit. so lets not go that road again. Slight ring is normal and the price you pay to hear a signal or not hear it. Thanks ..

Re: [Elecraft] APF in 4.16/2.63 works well!
I've been a major perponant of having the Dual PB disapear from the front of the rig (even though I'm with the 1% of others that use it)... I would be okay with a HOLD push that toggles the two features on and off. One hold turns on Dual PB, the next turns on APF the thrid turns which ever off.. This isn't ideal by any means, but it could solve the issue of having to go back into the config menu to turn it on and off. Long and Short holds are just the same as toggles... Sorry folks but my 80 year old ham buddy just can't control his hand long enough to know how long 500ms is vs 1 second. He can barely click a mouse two times in a row to open a program. I guess if the Dual PB was that important to you, you could always just keep the config menu option on a quick key.. That's what I'll end up doing.

I've had a chance to preview the APF function and it seems to operate very well although I haven't seen a any really weak stations like 5R8RJ on 160. APF as implemented by Lyle may become an alternative to a very narrow (e.g. 250 or 200 Hz) CW filter for casual operators as it provides a spotlight selectivity but does not provide the same level of IF protection as the tighter first IF filter. The one reservation I have is the potential need to use the menu system to select between the original Dual PB filter and APF. I would much prefer to see a two level hold - normal (500 ms) hold for Dual PB and long (1 sec) hold for APF like Link and Diversity with the KRX3 - for selecting Dual PB or APF.

It seems to work very well and I expect it will be released publicly soon. APF (as implemented in the FT-1000) has always been a weak signal receiving tool. It's not for adjusting PITCH or some of the other ideas discussed. Last night I happened to be listening on 160m around 02z just after I got it installed. 5R8RJ usually comes on 1826.44 a little before his sunrise. Conditions were very poor but he was spotted by a UA4 around 0210z. I could hear nothing of him on his normal frequency. CW Skimmer's waterfall was also showing absolutely no signal there...not even a faint trace. I then actuated APF and could then copy him about Q3 in the noise. This is exactly what APF is designed for...pulling extremely weak signals out of noise...and it does it very well. The user interface is also very simple. Although it may change slightly before public release, you hold DUAL PB (as though you were going into the previous CW focus mode) and then adjust SHIFT in 10 Hz steps to peak the signal (independent of your PITCH setting).

Re: [Elecraft] Case for XG2
Hey Joe, I make a number of enclosures for Elecraft's line of mini-modules. They are made of clear polycarbonate which is about 250 times stronger than glass and they show off your hard work quite nicely. I have never advertised them, but last spring I made up a line of enclosures to cover the test bench modules (i.e. XG2, NGen, CP1 etc.). At the request of a couple of hams, I made them the same size and height so that they may be stacked on each other to reduce the amount of footprint on the bench when not in use. I externalized BNC connections and jacks where applicable and provided a sliding top for access to other controls on the various boards. The sliding top is held in the closed position with magnetic strip. I made a few of these for a few hams who all reported they like them. I can send you some pics if you like. I'd price them out at $15.95 a piece with $8.50 SH. I can certainly put 2-3 in the same shipping box if you desire enclosures for other test modules to save on the shipping. Here is a link to my enclosure page for the other enclosures I make so you can get a feel for what they might look like: http://w8fgu.home.comcast.net/~w8fgu/enclosures.html Feel free to email me offline if you have any questions.

Re: [Elecraft] [K3] How much compression for contest use?
There's a separate setting for line-in gain, which is adjusted using the MIC control when MAIN:MIC-SEL is set to line-in. Compression and TX EQ still apply (in phone modes). A good reason to route audio though the computer would be to utilise software digital voice keying, where you can have the computer record your voice (on the fly), and play it back. The CM500 works well for this, as it's designed to work with sound cards, where the Heil HC-4 (etc) elements require a lot of boost to drive a sound card mic input. ~Iain / N6ML On Fri, Oct 29, 2010 at 10:10 AM, n...@widomaker.com wrote: I use my CM500 on 'RP.L bias' with mic gain set to around 12-15 and compression less than 20.

Re: [Elecraft] APF in 4.16/2.63 works well!
I Completely agree with this idea of Q adjustments! I think that putting it on the Width as a TAP is a great idea. I do NOT want to loose my width control at all! but having a Tap to Q setting would be very nice indeed, and almost a MUST. I don't believe that it belongs on the shift knob since it has nothing to do with that nomenclature. Again, I'm going to push for my idea where the outside lines displayed are the Filter width, the inner lines display the Q, the shift moves the Q around within the Passband, or even outside of it if that's what you're doing. If you have your Width filter at 50 Hz and the Q is closed all the way down, the two lines (inside and out) would overlap each other, or sit right next to each other (assuming you were centered in the IF position) Date: Fri, 29 Oct 2010 12:58:46 -0400 From: olin...@bellsouth.net To: drew...@verizon.net CC: Elecraft@mailman.qth.net; btipp...@alum.mit.edu Subject: Re: [Elecraft] APF in 4.16/2.63 works well!

You could do the same thing with SHIFT to go back and forth between adjusting Roofing/DSP SHIFT displaying FC *0.45 and APF *0.45. Using WIDTH to control Q is intuitive. When APF is in there is no moderate setting, it takes over the passband and makes copy of a signal up band difficult.

[Elecraft] [K3} Why route microphone through a sound card?
The compression control and TX EQ work normally. Gain has to be set from the menu, for the Line In jack. There are a couple of reasons why I do it this way. Mainly, it's because I need to reset my Run F1 message on the fly when operating split on the low bands. Say I want to operate 40m at 7130, listening 7065 - with N1MM Logger I hold Ctrl+Shift+F1 and record a CQ specifying that frequency. Then if I have to move my listening frequency again, I rerecord as I transmit. It's also convenient to be able to set my live audio and the recorded audio to the same level. and thereafter adjust both with a single control. I do this with a dummy load and I'm all set. Thereafter, if I need to adjust, I do it with the master playback gain of the audio mixer on my sound card, and needn't touch the radio. And finally, putting both live and recorded audio through the same channel helps to make sure they sound the same, even if the sound card adds some white noise or unintentional shaping. 73, Pete N4ZR The World Contest Station Database, updated daily at www.conteststations.com The Reverse Beacon Network at http://reversebeacon.net, blog at reversebeacon.blogspot.com, spots at telnet.reversebeacon.net, port 7000 On 10/29/2010 1:10 PM, n...@widomaker.com wrote: Could you explain why you are going thru a sound card to the LINE IN on the K3?

I'm sorry but I'm not going to sit idly by while some other ham who's in love with his 1980's FT-1000 dictates why I can't have a Q setting on my rig. The Q is a necessary part of this feature in my mind. This is NOT an FT-1000 this is a K3. Just because your old rig used to work well for you without a Q has nothing to do with my new rig. And if you must make comparisons, than you can use the FT-2000 and it's contour filter (APF) which does have it's variable Q and boost level... Both living in the menus... Sorry but times move on, and you should too. Only the IDEA of the APF was conceived from the FT-1000, not the entire design and implementation... Please don't limit the rest of us.

Re: [Elecraft] APF in 4.16/2.63 works well!

Re: [Elecraft] APF in 4.16/2.63 works well!
I'm sorry but I'm not going to sit idly by while some other ham who'sin love with his 1980's FT-1000 dictates why I can't have a Q setting on my rig. The Q is a necessary part of this feature in my mind. If you want a low Q peaking filter, it's already present in the Dual PB filter. Select it and use the Width control to set the Q you want. A low Q peaking filter is not what those who originally proposed the feature and have advocated regularly for it are after. As has already been said, de-Qing the filter currently in Field Test will render it useless just like Yaesu did when they tried to eliminate the ringing in the FT-1000D (and like the poor imitation contour filter in the FT-2000/FT-5000/FT-9000). The K3 Dual PB filter performs better than the contour filter in the FT-2000 that is gathering dust in my closet. The new APF is light years ahead of that when used *for the intended purpose.* Thanks to Lyle and Wayne, K3 users will soon have two tools - each designed for a different set of operating conditions. Please do not dull the scalpel by trying to make it cut lumber. 73, ...

[Elecraft] P3 Questions
I may need some assistance on how my P3 should act. My P3 arrived while I was away on an extended trip to the Northwest. I now have it up and running, but I have some questions. I've perused the manual, including the newer version on the website. It seems that my levels may be wrong, but not sure. Here's what I have done--I updated my K3 firmware to the latest version on the website. I also updated the P3 firmware. I also had to make the mod to my K3 (#96) for the I.F. output gain. Prior to making that modification, the noise level seemed to be around -110 dbm, but that was also before I updated my K3 firmware also. Now, I seem to have a reference level way down to around -140 dbm. I do see signal spikes, but it seems to take an S8 or S9 signal to really show on my screen (to differentiate them from just noise), which I assume is indicative of my noise floor. None of the illustrations in the manual show something starting that low. It makes me wonder if I did the K3 mod properly. I did replace the SMT part with the supplied SMT device (or think I did!). Hopefully I didn't screw that up. All of this scaling varies from band to band somewhat, but it's always -120 dbm or lower. I see nice spikes from stronger signals, but some that are quite copiable on the K3 don't seem to make much of a spike at all. The waterfall does seem to show the signal better in those cases. I'm assuming it's just because those signals are right at the noise level, but I was primarily concerned about the fact that my setting has to be so much lower (higher numberical value of minus dbm) than anything shown in the manual.

Re: [Elecraft] Special List
Hi Richard, Like most high-tech companies, we perform a lot of internal testing of our products before we release them using very small groups of 'alpha tester' customers. It certainly is not a privileged group. :-) In this case, we are testing the APF function in a -partially- completed version of K3 firmware that is not quite ready for wider release. (All of the matching menu entries are not completed) This gives us early and fast feedback on any issues. Its also agreed by participants that testing at this stage runs the risk of unforeseen problems, which is why we do this first at a very small scale before the next stage of release. The last thing we want to do is to unleash extremely early K3 code on a broad swath customers. Once it passes the alpha test level we then release it on the web site as -beta- software for those that wish to try out early releases. At that stage it is usually very stable and most feedback relates to minor changes in operation etc. Once we see good response from that group, we then go to final release on the web site. In this case the feedback from the testers was so positive that we allowed them to go public with their comments. We will be releasing the code as beta on the web as soon as we add the additional menu features. Overall our goal is top provide the highest level of quality possible. this process really helps us get there quickly. 73, Eric WA6HHQ www.elecraft.com --- On 10/29/2010 9:57 AM, Richard Thorpe wrote: I would like to propose a special list for the chosen beta testers to boast to each other about their special connection to the powers at elecraft and new software that the vast unwashed is not ready to receive.

Re: [Elecraft] APF in 4.16/2.63 works well!
Variable Q might be nice, it seems a pretty good compromise as is though. the issue I would have with putting the Q on the width control is that this then prevents the user altering the IF filter bandwidth when the APF is selected Currently I am finding that I am still playing with the IF width control quite a bit when APF is selected so far on 160m the APF feature is able to help dig out signals that are too poor to dig out by ear without it.

[Elecraft] Special List
Dear Friends, Surely one can understand a small group of people being used as Alpha not Beta testers. The problems for Elecraft could become excessive if every partially developed change was released onto the rest of us. The testers are not limited to W land, I know that Brendan Minish in EI land is also a tester. Let us live with this system which works well and be happy that our radio is still improving! I can hardly believe the service we receive from Elecraft. I second the Viva Elecraft comment! Life is indeed good. 73 Doug EI2CN __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

[Elecraft] K3 - ATU Tune
Hi, Something curious has happened to my K3 SN 3975 - when I tap the ATU Tune button the power out shown on an external power meter is full power, a little over 100W. The K3 power out indicator also kicks up to full power. I have the unit set to 50W and when I key it normally (CW) it shows 50W on both the external and internal meters. The SWR is fine. Any thoughts on anything I might have done to cause this?

[Elecraft] K3: LPA power level accuracy?
Hello fellow Elecrafters, Quick question - I've noticed that when using the LPA, output power is always slightly off compared to the reading given off by two fairly accurate meters. For example, a constant carrier output of 5 watts always reads about a half-watt less on the external meters. The output power from the KPA3 however has always been on the dot - 80 watts drive reads 80 on the meter, 100 watts output reads 100W on the meter, etc. etc. I'm not really concerned, but was wondering if this was typical? I've calibrated several times in the past using the K3 utility, but the results are usually the same. -- 73 de James K2QI President UNARC/4U1UN __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] K3: LPA power level accuracy?
No, wasn't aware of that. It's been a while since I've delved into the K3's menus. Do you know what that option is called, or where to find it in the manual? Also, just to make sure I'm understanding you correctly - do you mean to suggest that if the K3's watt meter reads 5W, but actual output power is 4.5W, you can adjust output power to match the K3's meter? As it is, the K3's meter and LPA power settings do not match the readings displayed on my outboard analog and digital forward power meters. When the LPA is in use, displayed power is always a .5 to 1 watt lower on the external meters. 73 de James K2QI On Fri, Oct 29, 2010 at 5:04 PM, The Smiths notforc...@hotmail.com wrote: There's also an adjustment that you can make manually to move the power up or down from what the meter is reflecting on the K3, have you tried that too?

Re: [Elecraft] P3 Questions
A noise level of -140 dBm is reasonable with no antenna connected or a quiet band. It also depends on the span and how you have the K3 set up. On mine, the noise level is around -160 dBm with no antenna connected to the K3, the K3 preamp turned on, and the span set to 2 kHz. If I turn off the preamp, turn on the attenuator, and set the span to 200 kHz, the noise level is a little below -120 dBm. With an antenna connected it is higher than that. You can get an idea if everything is working right by comparing the K3 S-meter reading of a signal within the receive passband. S9 should show as roughly -73 dBm on the P3 display and change by 6 dB per S-unit below that. There's a table of dBm levels versus S-units in the latest P3 manual.

I now have it up and running, but I have some questions. I've perused the manual, including the newer version on the website. It seems that my levels may be wrong, but not sure. Here's what I have done--I updated my K3 firmware to the latest version on the website. I also updated the P3 firmware. I also had to make the mod to my K3 (#96) for the I.F. output gain. Prior to making that modification, the noise level seemed to be around -110 dbm, but that was also before I updated my K3 firmware also. Now, I seem to have a reference level way down to around -140 dbm. I do see signal spikes, but it seems to take an S8 or S9 signal to really show on my screen (to differentiate them from just noise), which I assume is indicative of my noise floor. None of the illustrations in the manual show something starting that low. It makes me wonder if I did the K3 mod properly. I did replace the SMT part with the supplied SMT device (or think I did!). Hopefully I didn't screw that up. All of this scaling varies from band to band somewhat, but it's always -120 dbm or lower. I see nice spikes from stronger signals, but some that are quite copiable on the K3 don't seem to make much of a spike at all. The waterfall does seem to show the signal better in those cases. I'm assuming it's just because those signals are right at the noise level, but I was primarily concerned about the fact that my setting has to be so much lower (higher numberical value of minus dbm) than anything shown in the manual.

Re: [Elecraft] K3: LPA power level accuracy?
James, You are beginning to venture on a losing battle!! What used to be the 'old reliable' Bird watt meters had an accuracy of +/- 5%. Typical ham watt meters, especially the ones that use diodes to produce forward and reflected power, typically never mention an accuracy specification. You will also notice that for a given constant load, the same watt meter will change the SWR reading as you change your power. As you know, SWR is not a function of RF output power! 4.5 watts is 10% of 5 watts and if you change watt meters you are going to get a completely different answer. Very few watt meters are calibrated to any standard and if they are, they most likely are not recalibrated once a year. The only solution to the answer you are seeking is $$! 'Close enough' will have to do with watt meters.

I've calibrated several times in the past using the K3 utility, but the results are usually the same. -- 73 de James K2QI President UNARC/4U1UN __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html -- 73 de James K2QI President UNARC/4U1UN __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] Case for XG2
That's correct. To measure MDS you have to reduce the XG2 signal with an external attenuator to around -140 dBm. Leakage from the XG2 into the receiver by radiation may make that impossible. This also depends on how well the receiver itself is shielded, as well as how well the cables to it are filtered, etc. One easy way to tell if you have a leakage problem is to actually listen to the receiver as you increase the attenuation. The signal should quite abruptly drop below the noise and become completely inaudible. I found that with the K3, the leakage from the unshielded XG2 was too high, though it worked fine with another transceiver. This, of course, is no shortcoming of the K3; that other transceiver outweighs it about 6 to 1.

Re: [Elecraft] Case for XG2
Scott, Despite the leakage, the XG1 is quite useful for MDS measurements. The calculation given in the manual using readings made at the 1 uV level will come within a dB or two of MDS measurements made using the traditional method of a well shielded, calibrated low level generator followed by a step attenuator. If you wish to use the XG2 for that traditional MDS measurement method, it must be placed in a shielded enclosure, and I believe you should also change the BNC connector because its plastic case would allow sufficient leakage to skew the measurement data. 73, Don W3FPR On 10/29/2010 7:02 PM, Scott Ellington wrote: That's correct.

Re: [Elecraft] Case for XG2
Thank you for a very concise reply. If I were to put some kind of sheildng in the case like aluminum tape or something like it. Would that work? What would you like to see for something like this?

[Elecraft] K3. Hi/lo cut
It was mentioned in the roofing or if filter post that using hi/lo cut was easier than bandwidth shift. That you can see the filters change as you bring hi cut down. I thought width and shift was in the I F and cut in the audio. Are they essentially the same or have the same effect ? Signed confused Happy QSO'ing.
