Re: [Elecraft] Re: Hexkey
Never used a Hexkey here. Tried the Bencher paddles and disliked them very much. I have two paddles I use with automatic keyers: Old Vibroplex vibrokeyer which is nothing more than a shortened and reworked bug, and the German Palm Key. The Palmkey is very small, but has a great feel to it. I don't use the iambic key imbically. I'm from the very old school of the Vibroplex bug and Johnson/Mac keys. Wish I still had a Mac Key! My avorite Vibroplex pattern is the Champion/Lightning Bug flat lever key. I had an Original and even a Presentation once. Didn't like them near as much as the cheaper flat pattern ones. I also have a very beat up Blue Racer which does a nice job, but always had to add weight to them to make them go slower than 30 WPM dits! 73, Sandy W5TVW - Original Message - From: Ron D'Eau Claire [EMAIL PROTECTED] To: elecraft@mailman.qth.net Sent: Saturday, April 14, 2007 1:09 PM Subject: RE: [Elecraft] Re: Hexkey Why would you reverse the normal thumb for dits, index finger for dashes setup? That's been standard since the first bugs and carried over unchanged into the paddle/keyers. It sounds like you are running into an essential difference in sending that has shown up since keyers became common. Although both bugs and keyers typically use side-by-side paddles, there are substantial differences in how they are operated. A bug requires significant mechanical force and movement to operate the dit pendulum to make dits and then stop them at the right moment. Several designs have attempted to reduce the demands of a mechanical bug, but it's still a huge amount of movement and energy compared to simply accomplishing the contact closure a keyer needs. Many newer CW ops who never used a bug developed a preference for very close-spaced contacts that can be operated with a feather touch on the paddles. That's completely at odds with the action needed for a bug. Many paddles designed for use with keyers - particularly the earlier paddles - featured movement and springs much like a mechanical bug: lots of throw and relatively stiff springs. They were operated like a bug - usually rolling the whole arm side to side with the fingers held steady to contact the paddles with sufficient force without wearing out one's finger muscles! The original Vibroplex paddles were one of those designs, like my Scotia and HamKey paddles. Then came the light touch designs designed to work with an absolute minimum of movement and force. The Bencher was an early one. People used to a mechanical bug tended to knock them apart just sending a CQ! Newer operators learned to hold their arm still and lightly caress the paddles with their fingertips. Used that way, they work fine. I can't speak for the HexKey. I use my Speed-X or Vibroplex Bugs at home and my KXPD1 paddles in the field where it's not practical to haul a bug. The KXPD1 paddles, by the way, are able to deal with my fist without complaint. The bottom line is that it all comes down to how you want to operate the key: strong rolling fist like a bug operator or the feather touch of a keyer operator? If the former, you need to find someone who has really pounded on the HexKey to be sure it will survive long. There was a secondary problem with the first Bencher that deserves checking on any modern paddles. The Bencher uses a single spring that is stretched around a chrome-plated post in the back. Bumping the key in just the wrong way would dislodge that spring, causing it and the paddles to fly off of the base! I suspect the designer assumed they'd be treated like a bug - NOT bumped! The sensitive springs and pendulum of a bug can be damaged by careless handling, but operators not used to bugs tended to assume the paddles were as structurally sound as any straight key. Not so, unfortunately, and dropping or banging a Bencher was inviting time spent looking for the spring and paddle mechanisms behind the operating desk or on the floor somewhere.

Re: [Elecraft] K2 or K1?
Depends on what you want it for. If you bare thinking about a new all-mode, all-band rig, I'd certainly choose the K2, 160 meter and SSB add-ons. Maybe even the 100 watt model. If you are interested in QRP, a pack rig, CW only, and you can cope with just having 40-15 (4 band) or changing two band cards, then I'd say the K1 was right for you. I have a K1 originally b ought with 4 band option which I setup for 40/30/20/15 meters. I have an extra two band RF board for 160/80 meters. Also have the KAT1 internal tuner. If I did it all over again, I'd skip the KAT1 and purchase the external T-1 tuner as it has greater matching range. It is a really great rig. I did not care for the internal battery option as it is a pain taking the batteries in and out for charging.

Re: [Elecraft] HF amp kits
I built an HF amplifier kit a couple of years ago. The HF Packer amplifier. It was around $125. All the parts were there and some things have to be done by the builder that normally are pre fabbed. Drilling and tapping holes, placing parts in enclosures accurately. The amplifier is fairly small and uses two low priced MOS Power FET transistors. With about 2-3 watts of drive it will produce 35-40 watts of output. Very nice filtering arrangement on the output, switchable froom 160-10 meters. Has an RF actuated changeover relay system and it is linear for SSB use. My K1 drives it easily and quite well. 73, Sandy W5TVW Google HF packer for website and details. - Original Message - From: David Wilburn [EMAIL PROTECTED] To: Elecraft Reflector elecraft@mailman.qth.net Sent: Thursday, April 05, 2007 4:57 PM Subject: Re: [Elecraft] HF amp kits Just working from memory here, but wasn't there also a limit that the amateur could only build one such amp a year?

Home-made amplifiers do not require certification. They must still meet some standards, such as those involving purity of emissions (harmonics, for example) and of course must not be operated above 1500 watts PEP, but that's pretty much it. I am unsure of how the rule applies to kits, but I think they would be considered a manufactured product if all the parts needed to complete the amplifier are contained, in the kit. If, however, a kit contained only some of the parts, and could not in itself be assembled into a working amplifier without adding extra parts, then the certification rule probably would not apply. It would be perfectly legal for a ham to build a home-brew grid-driven amplifier that could take the 10 watt signal from his K2 and boost it to 1500 watts output. Such an amplifier would have (roughly) 22 db of gain. A pair of 4CX800 tubes could accomplish this, I think.

Re: [Elecraft] AGC Independent S-Meter?
What I was referring to is the common circuits used in most receivers of olden days. (Tube era) Most receivers depended on the AGC level for signal strength indication. At best a large approximation and some wishful thinking. Not only do 50 microvolt (if that's your standard) S-9 levels vary from band to band, but also at the high and low ends of the bands as well. I have dealt with Field strength meters where the S meter actually indicates microvolts per meter, and they go thru some rather careful procedures to make sure the receiver's gain is the same wherever the measurements are made. I've never used the H-P instruments that are popular on the 500 Khz experimental band at present. Anyway, the short of it is one can't depend on an S meter on a 'communications receiver' to really be accurate. No matter who makes the receiver generally. Unless it is some special purpose device especially made for measuring the input levels. One of the silliest ideas I have ever seen was when Bill Halligan's folks put that HUGE 4-1/2 S meter on the S-76 when they came out with it. I personally thought that they'd have done better if they had just jeft the loudspeaker there and offered an external S meter. The S-76 was a big improvement over the old S-40, but why that big meter?

Sandy, As far as I know, there is no direct relationship between the strength of a signal and receiver AGC. My AD8307 power meter can measure signal strengths directly off an antenna if called upon to do that, it goes down to -80 dBm (about S-8) with no other amplification. This is strictly a power meter, no AGC implied or implemented - the output is the base 10 logarithm of the input signal. All one must do is measure the strength of the received signal to drive an S-meter - but it must be calibrated if it is used as an absolute measurement device. Yes, the implementation in most receivers derive the AGC voltage from the same signal strength measurement circuits, so things get a bit mixed up, and often appear as a 'chicken and egg' situation. 73, Don W3FPR -Original Message- Circuitrywise, an AGC/AVC free S-meter is an oxymoron!

Until recently 1800-1820 was fairly free from DXing. Some of the newbies are beginning to remind me of the RTTY bunch on the higher bands, especially 40. Keep outta 'digital' territory, but the whole band is ours during a RTTY contest! QRP can be very challenging, especially on 160. This makes it fun, but the DXers are beginning to run off the ragchewers, what few of them are left. SSB splits have ruined 40 CW during SSB contests involving DX stations, and with 80 cut down to 100 khz. on CW, I'm afriad the same thing will happen there soon.

The roll-off of the elliptical low pass filters on the four-band filter board is much sharper and deeper than that of the very simple filters of the two-band board. I've never seen any spurious-output specs for a four-band K1, but since the two-band K1 has the best figure for spurious output of any Elecraft rig, the four-band K1 can only be even better. It has better performance than the two-band 40m/20m board, and twice the the available bands (including 15m, IMHO the best QRP band when open). How could one beat that combination of *both* improved versatility and improved performance? If I did it all over again, I'd opt for the little external tuner (T1?) instead of the internal tuner. I really like the internal tuner, even though currently mine has recently developed a yet un-diagnosed problem and now never returns a VSWR less than 9.99, even into a dummy load. I tried the KBT1 for more than a year, but eventually discarded it.

Re: [Elecraft] Attic Antenna
WARNING! This same scheme (scam?) happened quite a few years ago. Don't remember the name of the device, but is was a black box type proprietary antenna coupler. The price was rather high ($300-400) and it was guaranteed flat SWR between 3-30 Mhz. SO-239 input and two standoff insulators with wing nuts (output). Was said to match a random wire or a balanced line dipole! Someone finally x-rayed one and it turned out to be a dummy load actually. It was enclosed in a cast aluminum Bud box and potted with some sort of opaque epoxy if you took the lid off! They didn't last too long, but long enough for the manufacturer to make a bundle! It was not guaranteed to radiate with high efficiency but was guaranteed to have an input VSWR no greater than 2:1! BEWARE of ANY MAGIC DEVICE that makes these claims. More than likely it is a large pile of bovine fecal matter that they are feeding you! No, I didn't buy one, but in some unusual installations it was tried on some commercial marine limited coast station installations. The results were very mediocre no matter what 'antenna' was tried.

Re: [Elecraft] Attic Antenna
My usual antenna on a quick setup afield is a 33' vertical wire hoisted by an MFJ-1910 33' fibreglass telescopic pole. This wih a K1 and KAT1 internal tuner. It will tune with no radials but the performance is lousy. Add one 33' radial and it gets much, much better. Add TWO 33' radials and much better yet. If I add two more (a total of four 33' radials and it improves more yet but not a large change. If I add more, hardly notice any change at all for the most part. All radials out of #24 hookup wire and laid on the ground. This for 40 thru 15 meter operation. For 80 meter use a 66' antenna, 33' vertical and the rest to a nearby tree limb from top of the support mast. Sort of an inverted L. This with 2-4 radials 66' long. It works but isn't the best I could do with a better antenna. My trials of whips and short verticals has been dismal. They will work but somewhat poorly so say the least. The MFJ pole and 33' wires seem to be the best setup especially in places where you have trouble finding supports like the middle of a parking lot or field! It won't work where there is a lot of 'foot traffic' or kids as they will constantly be fouling the radials!! Tried all sorts of loading schemes with whips from 4' to 15' and results fair on higher bands (15/20) but very marginal on 40 or lower. also tried shortened loaded dipoles and again it works but poorly. Sometimes you get lucky.

Re: [Elecraft] 80 m CW and Digital Operation
Firstly, I want to state I do not imply that the RTTY bunch has run away with 40 meters. All in all, they have, along with the other digital modes, pretty much stayed within the sub band/band plan Gentlemen's Agreement for the appropriate emissions except for contest time when almost everyone goes bonkers. Someone else took up my flag in another post somewhere recently about weekenders who have no place to make casual QSO's on contest weekends. More on that later. I am glad someone is recognizing that separation of modes purely by bandwidth, appears to have merit or is a solution to a potential interference problem, is really not the answer. Some digital modes can compact a very large numbers of QSO's into a very narrow space, while other do not. PSK is an example of the cramming of stations every 100-200Hz is viable. If one PACTOR station comes on in the 3-4 Khz most PSK stations operate it can cause havoc! One strong PACTOR or MFSK station can raise all sorts of hell in PSK space or CW space. This is greatly compounded by a few who totally ignore any mode except the one they are using. Thank goodness it isn't the norm! It does come across to newbies in amateur radio that this practice is OK to some I'm sure, but should be discouraged. Separation of digital and CW is essential if we are all going to live together and have any harmony at all, or maintain communications instead of bedlam. Further, we must also maintain separation of narrow band digital modes (PSK for example) and wider digital modes (PACTOR and wider modes). Any AUTOMATIC or ROBOT internet access stations should be limited to a very small chunk of spectrum, especially those using proprietary systems. In my humble opinion, HF access to internet via Amateur Radio is opening up a very large can of worms that will eventually come back to bite us in our posteriors! There IS a radio service for this via the MARISAT satellite system to do this for you rich yachtsmen out there. It should not be via Amateur Radio. SSB/digital radiotelephony will continue to demand more spectrum space in the future, no doubt, but room must be maintained for older modes as well. Especially for last ditch emergency and relief operations as well as simple old fashioned ragchewing. In keeping with efforts to not monopolize spectrum space, a lot of contests now specify a band of frequencies to be used during these contests. This allows some space for casual QSO's for those who do not wish to operate a particular contest, but still would like to QSO friends, etc. On contest weekends. This procedure is practically impossible to maintain during the very large contests like CQ WWDX, ARRL DX, Sweepstakes, etc. It would be nice to have a very small area (5 khz on CW or Digital bands, 10 khz on SSB/voice mode bands) reserved for this purpose? Something to think about when designing a band plan. We all will have to work at it to make smaller amounts of spectrum space to all concerned. Rest assured the FCC these days doesn't give a damn about whatever QRM exists as long as it isn't interfering with another radio service under their jurisdiction and we stay within our assigned pieces of the spectrum. If we do not plan well, none of us will be able to pursue viable communications, especially in the HF spectrum as more people join our ranks. Just some thoughts for what they are worth, to keep our hobby alive and well in the future. 73, Sandy W5TVW - Original Message - From: Fred Jensen [EMAIL PROTECTED] To: Elecraft Reflector elecraft@mailman.qth.net Sent: Tuesday, October 17, 2006 8:42 PM Subject: Re: [Elecraft] 80 m CW and Digital Operation | Sandy W5TVW wrote: | | Some segregation is almost demanded if the CW/digital operations | are combined in a 100 khz. sub-band, no matter where it happens | to be.

Re: [Elecraft] 135 ft flat top antennas, again, ad infinitum
I would strongly warn everyone who uses this method of feeding the centerfed tuned feeder dipole about a problem with this. Let me start by saying I have done it and still do it with lowered powered rigs (under 100 watts). There IS a danger, that of overheating the 4:1 balun and losses in the balun ( or even destruction!) under some conditions. Most baluns want to see a relatively reactance free impedance transformation. Also one which is close to the transformation ratio (commonly 1:1 or 4:1) I use a 135' dipole at 50' with about 100 feet of 450 ohm line. The impedances presented to the generator are usually not (in my case) a 4:1 ratio or have a lot of inductive or capacitive reactance on some bands. Broadband baluns don't like this condition and when higher powers are used,the baluns will cause losses and/or overheat under these conditions. After playing with baluns for quite a number of years, I decided to try the old fashioned balanced line antenna tuner configuration instead of the T network high pass transmatch (most commonly available tuner) and a 4:1 or a 1:1 broadband balun. Yes, the balun WILL work under a lot of conditions but not really well. Only if the transformation ratio is in the ballpark or a high reactance condition does not exist and the feed point presented to the output end of the balun. A balun is no cure all or simple solution for a proper matching network, or the proper network for matching an unbalanced 50 ohm transmitter to a tuned feeder type dipole. I repeat: It WILL work or appear to work under a lot of circumstances, but often times is an inefficient way of doing things. One quickly finds out about this when using higher powers and when the conditions are not within the normal parameters of the balun. I repeat again, I have done this many times, but I usually cringe at doing it because of the reasons stated. If you are running QRP, you want every microwatt you can muster into the ether to be radiated, not thrown away as heat. Ditto for high powers, except at kilowatt levels, sometime improper devices will burn and smoke or at least get very hot. Why throw the power away? My two penny's worth. 73, Sandy W5TVW - Original Message - From: George [EMAIL PROTECTED] To: elecraft@mailman.qth.net Sent: Tuesday, October 03, 2006 3:23 PM Subject: [Elecraft] 135 ft flat top antennas, again, ad infinitum | My 2 cents worth is: Theory is one thing and actuality is another thing.

Re: [Elecraft] Re: Binaural CW Reception
Speaking of binaural reception. In this sense it is using a setup that is able to put the lower sideband information in the left ear and upper sideband information in the right ear. As one tunes thru a signal (SSB, or AM or CW with a product detector) it will appear to come from one side , go thru your head and go out the other ear! Some very interesting effects occur in so doing. If you have say an AM signal and it is phase locked to zero beat (true exalted carrier reception), you can very easily hear the selective fading in each sideband independently! One also gets a sense about which way to tune to make the signal appear in the right place. It also allows you hear which side of zero beat the signal is on. All these effects could be heard using an old General Electric YRS-1 SSB adapter, which was modified to allow ISB reception with stereo headphones. ISB reception is REALLY interesting and weird, hearing two programs at once! I don't know if there is any ISB feeders for the SWBC stations anymore, but there used to be. This way one channel could relay two separate programs at once on a single RF channel. Probably redundant now as I'm sure whatever is relayed now is via satellite link! This is just a comment in case someone, somewhere wanted to experiment with ISB reception using an ancient GE YRS-1 unit. 73, Sandy W5TVW - Original Message - From: Jerry Volpe [EMAIL PROTECTED] To: elecraft@mailman.qth.net Sent: Thursday, May 25, 2006 1:35 PM Subject: [Elecraft] Re: Binaural CW Reception | I have done a couple of Binaural CW reception projects and found the | results very appealing. Let me begin by sharing a few thoughts: | | 1. With binaural reception you normally would NOT use tight CW | bandwidths as the object is to allow more audible information to | be processed by our brain. I think that you would want at least 600Hz or | greater. I typically use a 1000Hz type filter or wider but generally | nothing tighter. A stereo 'soundscape' is created within your head with | the primary signal (the one centered in the Binaural filter) appearing | in the center of your head, and the ones higher in pitch progressively | off to one side and the ones lower in pitch off to the other side. | 2. Due to the sound dividing by frequency you notice only the lower | frequency background 'noise' component in one ear and the higher | frequency component in the other. It is surprising how much LESS in | intensity the noise is overall than what it was with combined energy to | both ears. This alone is worth the price of admission. | 3. Many of today's CW operators have not trained themselves to use their | own brain as a CW filter and instead rely on very sharp band-pass | filters for single-signal reception. Binaural CW reception provides | multiple signals which many find too confusing. | 4. Binaural CW reception should be great for NET, roundtable, and even | contesting where you often need to hear many stations on slightly | different frequencies. | | My first project was a stand-alone Binaural CW filter using a pair of OP | Amp ICs. Basically, the audio input passed into both a low pass filter | and a high pass filter with the low and high frequency cutoffs at the | desired center frequency 700 Hz for example. The output of the each | filter was further amplified (as needed) and then applied to either | stereo speakers or to stereo headphones. | PRO: Small package. Simple approach. Low cost. Easy to build. Works well | enough for a single design cross-over frequency. | CON: I could have used better quality OP Amps for lower distortion. The | ones I got were from Radio Shack (sigh). Still not bad. Can't change | cross-over frequency. This is OK if your receiver has a fixed CW offset. | Myself, I like to change my offset to minimize long term listening | fatigue. But then again only a couple of my transceivers allow for | that most don't. Another CON was the fact that I had to build this | filter. It was amazing to me how many hams were interested in the | project (I posted the info on the Ten-Tec reflector last year) but were | unwilling or unable to assemble a project without a kit. | | I think it would be wise to use two pass-band filters rather than a | low-pass and a high-pass configuration. That way you can also take away | the unnecessary lows... say below 300 Hz and the unnecessary highs | perhaps over 1500 Hz. These filters should not have sharp slopes as that | will add ringing. | | My second project began with the following in mind: | 1. Using band-pass filters rather than low-pass and high-pass. | 2. Include the ability to move the combined filter cross-over for | different CW offsets. | 3. Get the lowest distortion possible in the filtering. | 4. Use something commercially available rather than 'build your own'. | | My first thought was to obtain two SCAF audio filters (highly | programmable as far as band-pass characteristics, no ringing, low

Re: [Elecraft] K1 s/n 1031 has new home
Would be a bit of a problem switching between the 2 band board and the 4 band board. Space is somewhat at a premium inside the K1, especially if you have an autotuner (KAT1) installed. These two boards are piggy-backed above the main PCB. Could possibly be done with some very custom switching boards maybe installed on top cover. Interconnect would probably have to be via ribbon cables from 2 and 4 band PCB's to switching board. Also comes the problem of activating the actual switching process. Incorporate it into CPU chip? Just add a seperate 2/4 band pcb switch on rear apron somewhere? Even with this, each time it is switched, you would have to reassign bands again to bands 1 and 2.

We've been thru this before gentlemen. In a VERY busy contest, there ain't no such thing as a single frequency There is signals every 20-50 Hz! The BIG 160 meter contests are examples of this. If you are a DXer, how many times have you succeeded with only a 'single' call in a big pileup? You may have to send your call a bunch of times,and/or be running a bunch of power. If someone calls me just a single time and I send QRZ, I expect the other chap to have enough sense to send his call at least 2-3 times. Usually because static is the culprit or two or more callers QRMing each other. Either way you gotta repeat the call. In a contest, the highly abbreviated procedures are commonplace, but I still say it is lazyness or stupidity to apply the same logic to an answer to an everyday CQ call. Whoever isn't familiar with the protocol, it would behoove him to certainly learn it. What's the problem with that? It's just simple manners, like for example; Like learning not to pass gas loudly in church or on a crowded bus. (to cite a rather crude, but typical situation) If ARRL no longer teaches good operating skills, find out from an old timer, what they are. Sorry for the tirade, but I feel very strongly about this and think it a VERY large mistake that ARRL saw fit to take this section out of the Handbook. Maybe its because there are more LIDS than A1 operators in Newington now? 73, Sandy W5TVW - Original Message - From: Bill Coleman [EMAIL PROTECTED] To: Sandy W5TVW [EMAIL PROTECTED] Cc: [EMAIL PROTECTED]; [EMAIL PROTECTED]; elecraft@mailman.qth.net Sent: Tuesday, April 18, 2006 8:56 PM Subject: Re: [Elecraft] Is CW a Language?

Re: [Elecraft] K1 VFO frequency range change
This is the MAIN reason I changed the VFO span, to get up to 7100 to 7150 coverage.

Re: [Elecraft] Underground Antennas (WAS: Ham Ingenuity)
The only ground antenna I worked with was a 270 ft. horizontal loop made from #28 enemeled wire. It was in a pentagon shape and laying right on the ground. It loaded well with my antenna coupler thru a 1:1 homemade balun wound on a big 4 ferrite toroid form with about 12 turns trifilar wound #18 solid hookup wire. I worked quite well I thought, except the signals incoming and outgoing were down about 20 db. Even did a few QSO's on 40 and 20 meters with it QRP with the K1. NOT the most effective antenna by any means, but surely a good 'stealth' antenna for people in stuffy subdivisions with those stupid covenants! If I were going to make it a permanent installation I'd use some single conductor #14 solid insulated wire from Home Depot for protection against breakage. Any Nosy Neighborhood Association idiot snoop could be told it was a wire to keep dogs off your lawn, or to keep you dog in your yard with a special collar.

Re: [Elecraft] Re:QRP Antenna
I have had some very good results with the K1 and the following: 1- MFJ-1910 33' fiberglass telescoping pole. 5 ea. of 33' lengths of #24 guage hookup wire (the MIL-SPEC stuff with striped color coding on it. Any hookup wire is OK.) 1 ea 25' length of same hookup wire. I use a heavy photo tripod and bungee to anchor the pole. In wind you will need 3 gallon jugs full of water and more bungee to anchor the legs! Run a 33' wire up the MFJ mast and right into hot BNC jack pin, and two to four 33' radials to the ground side of BNC connector. I use a Pomona BNC to binding post adapter. This performs well on 40-15 meters with a built-in KAT1 tuner. Will work equally well with a small T network MFJ tuner if you don't have a KAT1. I even have four 67' length wires I use when I have the 160/80 meter RF board in the K1 on 80 meters. Three for radials and one for first 33' of vertical antenna and the other 33-34' drooping off to one side. The MFJ pole is convienant and sets up very quickly. No good for back-packing, but I don't worry about that as I'm too damned old for that kinda stuff anymore! This worked well when we lost power here for 10 days after Katrina struck the area!

Re: [Elecraft] KX1 with HF Packer Amp
That may be TOO much drive for the HF PAcker! I drive one on 160-20 meters with a K1 and it takes about 1.5-2.0 watts to make the HF Packer deliver 35 watts out. If you can't control the power output of the KX1, then you may have to change the values of the attenuator network in the input path of the HF Packer on the RF board therein. I have had fantastic results from my HF Packer. Only complaint is it needs a bit of modification of the hang time. Needs to be much shorter! OK for SSB but no good for CW contest/net activity. Ok for casual QSO's. Hang time once keyed is much too long for CW. 73, Sandy W5TVW - Original Message - From: Paul Webb [EMAIL PROTECTED] To: elecraft@mailman.qth.net Sent: Monday, February 06, 2006 12:04 PM Subject: [Elecraft] KX1 with HF Packer Amp | Some discussion lately on using the K2 to drive the HF Packer Amp.

Re: [Elecraft] Modifying Wattmeter Slugs for QRP
Bird makes (or made?) a model 4410 wattmeter that will do what you want. It looks identically to a model 43, except it has a single knob range switch on it. The ranges depend on the slug in use. Mine has a 1 KW max. 2-30 Mhz slug, which yield ranges from 0-1 watt to 0-1000 watts with a 1 and 3 scaling scheme. (1-3-10-30-100-300-1000 watts in this case). Very handy for low power stuff. VHF/UHF elements are available for it that go down into milliwatt ranges. It has a built in solid state amplifier that is run by a common 9v. transistor radio battery. They ain't cheap! When I bought this one years ago it was around $500 less elements. The elements were around $100 each at that time. I only have two elements for it. 1 KW 2-30 mhz and 1 kw 144-520 Mhz. (Both give the 1 watt to 1000 watt full scale ranges as per note above.) I sure can't afford to buy elements for it now!

Re: [Elecraft] K1, calling CQ, 2x QRP QSO.
A lot of people nowadays don't understand HF propagation. One MUST remember that the propagation programs are not necessarily correct! Many times bands are really open, but there isn't any activity. A lot of folks make a quick check, listen a minute or two and assume the band is dead. ALWAYS listen and ALWAYS call a few CQ's. You never know! A classic example of this is assuming 10,12,15 meters are beyond help. this part of the sunspot cycle. Many times it will be dead for East-West paths but open for North South paths, especially to South America from the USA. This is the great advantage of beacons in various places on 20-10 meters. Also weird anomalies will exist in propagation no computer program will predict. 73, Sandy W5TVW - Original Message - From: Darwin, Keith [EMAIL PROTECTED] To: Elecraft Discussion List elecraft@mailman.qth.net Sent: Monday, January 30, 2006 9:31 AM Subject: [Elecraft] K1, calling CQ, 2x QRP QSO. | I rarely call CQ - especially when running QRP.

Re: [Elecraft] Is CW a Language? OT
Operating protocol today is absolutely atrocious at times! A lot of the newer hams know nothing about really proper procedure and many are very short on manners! Biggest violation of all is when someone calls CQ, another station just answers W1ABC W1ABC K. Who is he calling? I usually respond by sending: QRZ? QRZ? DE W5TVW K. Often the other station will simply send W1ABC W1ABC K If the band is crowded, which it often is, this had NOT told me he is calling me! We have not yet established communication so the DE W1ABC or W1ABC IS NOT proper or polite procedure. Whether a station uses OP, NAME, HANDLE (or whatever) that is his preference, whatever turns his crank. Add to this the Novice accent heard STILL today NNQ NNQ NNQ NNQ NNQ DE W1ABC W1ABC.. repeated several times. Then a 5 second pause for an answer, followed by the same long CQ call again! One chap on 40 a few nights ago repeated this for maybe 5-6 times. I couldn't stand it any longer and fired up the 1/2 Kw and called him. He acted as if I was never there. Either deaf or has his receiver somewhere besides his frequency. Are ham license classes teaching proper procedures anymore? I KNOW the FCC doesn't give a damn. Perhaps a cell phone ringing, or someone passing gas loudly, or talking loudly in an office or church or theatre isn't considered RUDE anymore, so why try to have any manners in the ham bands? Sorry for the diatribe, but seems like too many of the newbies are not paying attention or don't care.

Re: [Elecraft] Is CW a Language? OT
I have taught many CW procedures classes in the past. I was also frequently tapped to explain tube amplifier classes, oscillator circuits, etc. as most of the people wanted to know this in addition to solid state gear theory. I did this umtil there seemed to be no interest in doing this anymore. This was the era when it seemed everyone was unloading vacuum tube gear, even throwing it in the dumpster at hamfests! The days when you could buy all the Johnson Viking Rangers you wanted for $20-40 TOPS, some in mint condition! Wished I'd bought some of them then! (If I did, I knew my XYL would raise hell about storing all that junk!) Most hams then were more interested in getting the code to 13 WPM and then forgetting it and working SSB 'phone. Anyone at the time that liked CW was usually checking into an ARRL NTS net and learned traffic net procedures and proper protocol. Contesting was popular, but the contests were rather far apart and few between, so most CW contesters would ragchew at times to keep their code speed up. No computers and 'code readers, and computers in those days for most hams. I find most CW operators are QRPers or are fooling with boatanchor/glowbug rigs nowadays. There are a FEW newbies that take to code like ducks to water. I'm afraid the realm of the telegrapher is getting smaller and smaller. It's ashame as Morse is a VERY unique communication system and an 'art'. The Amateurs and airplane pilots seem the only ones who still use it.

Re: [Elecraft] K1 with internal battery
I originally ordered my K1 with the internal battery accessory. Didn't like the little speaker at all compared to the larger one. Also the cells were a pain in the butt to install and remove for charging. I never thought about leakage, but that makes a lot of sense! I use a 10 cell holder with 2 A/H Ni MH batteries portable. Also have a cheapie $15 gellcell battery pack I bought from Sportsman's Guide that is super neat. The two 6 volt batteries in series are around 4 A/H as I recall. Pack has a nice shoulder strap, internal 10 amp fuse (the 5 X 20mm European type) in a holder. I took loose the cigar lighter receptical and installed a two wire Anderson Powerpole connector on the lead. Everything I have now That works on a 12-15 volt DC supply has the Powerpole connectors on them.

Re: [Elecraft] K-1 Mobile
I ran a lot of QRP mobile some years ago. I used a Newtronics Hustler at the time. Since then I used what's called a Bug catcher. It is simply a center loaded whip. Lower section was 3' then a section of Inductor about 3 in diameter on a piece of PVC pipe with a flyiong lead and an alligator clip to select the coil tap. Upper section of whip about 5' long. From the base of the whip to ground I used a liottle box that switched in capacitors from the base of antenna to ground to make the impedance closer to 25-50 ohms depending on the band. That rig worked the BEST! It looked rather gawky, but it did work! I have not had a lot of luck with other antennas for QRP operation. Too inefficient. I changed over from the Hustler whip to the bug catcher configuration when I went QRO mobile and found out the damned loading coil was getting warm wasting a lot of power! The Bug catcher configuration worked fine with an old Ten-Tec Argonaut transceiver tha ran about 3-4 watts out on SSB or CW. I hear the screwdriver antenna work OK, but I would have to be convinced of that before I spent money on one! I KNOW the Bug catcher type antennas work great.

Re: RE: [Elecraft] Sad day for amateur radio
I'm in the same boat! I struggled with code for a long time. Finally got in when the Novice Class was started in 1951! I took my test the month after it started. I didn't get an Extra until 1968! The code was still a struggle! I did take the Extra as a warmup for 2nd Class Radiotelegraph, which was required for my job! Passed both of them the second try. As I worked with code on the ships, I began to see the uniqueness of it! You can send and receive messages in a foriegn language you can't speak or read using CW! Amazing! No computers required, no interpreters required! I've been practically on nothing but CW now for about 20 years. It's a great mode when you have a sore throat and can't talk!

Re: [Elecraft] Re: KX1 PSK31? [how about FSK?]
Not REALLY being interested in SSB, I was fascinated by the I0CG conversion
for the K1, but only for PSK. As far as a new rig from Elecraft, I'd be more
interested in one similar to the K1, but with CW and PSK capabilities.
Filter wise, possibly a frequency agile receiver filter bandpass
bandwidth (1.5 khz-.05 khz) and bandpass center frequency variable
over whatever the audio range would be (500-2500 Hz?)

Re: [Elecraft] Multicore solder availability
I bought a pound about 6 months ago from a local distributor who does not stock it anymore. It was one of the last rolls they had. I also bought a pound of Kester 44.

Only if it has locked multivibrator circuitry in it to give you precision markers at 100 Khz intervals. Better yet 10 and 1 khz intervals.

Re: [Elecraft] Long wire balun question
Have used vertically polarized antennas extensively in the field with added radials/counterpoise wires. Usually laid on the ground.

Adding more give slight changes for the better, but nothing of a large difference. I'd say four would be the maximum needed. More is always better as regards radilas, but after 4 the returns increasingly diminish. 73, Sandy W5TVW - Original Message - From: John Rader [EMAIL PROTECTED] To: [EMAIL PROTECTED] Cc: Elecraft Discussion List elecraft@mailman.qth.net Sent: Monday, August 02, 2004 10:03 AM Subject: Re: [Elecraft] Long wire balun question | Don, | I currently have the antenna attached to a good earth ground and will add | radials for each band per your suggestion.
