Re: [Elecraft] [K3] Wine Update Software

All else being equal, more samples per Hz is better, as is more bits per sample. This doesn't make sense to me. In a quadrature system, you only need to sample at a sampling *rate* equal to the bandwidth (you meet the Nyquist condition because the I and Q samples effectively double the rate). In practice you would want to sample based on the skirt bandwidth, not the nose bandwidth. I believe some DSP based receivers actually sample a band limited IF directly, at the bandwidth dictated sampling rate.

Re: [Elecraft] [K2] Is TX frequency susceptible to RF on chassis?
Hi David! For fine tune C22 you can use the simplest method with PC and specrpogram. There is the original UA6HJQ's method: -connect K2's AF-out to PC mic-input, and phones to PC phone out; -turn On K2 and PC, and wait for 50-60 minutes (for temperature stability); -check the connection TP1=Control Board; -run the Spectrogram, and set for it: Scale -60db, FFT 8192, Band 640 - 1329Hz and set marker to 1000Hz; -set LSB-mode, and tune VFO at 10001,00kHz (WWV), if ANT is connected you have to hear WWV-signals in headphones, -if we see the WWV-signal peaked on 1000Hz (our marker on Spectrogram), it's the ideal point for C22. -if not, turn VFO for peaking the WWV-signal at 1000Hz-marker. -f.e. if we have 10001,20kHz we'll have to subtract 20 (in later steps), if we have 1,80 we'll have to add 20 (in later steps) - MENU = CAL = CAL FCTR (don't touch VFO-knob!) - we can see 14914,70 (for example) - now if we had 10001,20 we must to subtract: 14914,70-20=14914,50 (if we had 1,80 = 14914,70+20=14914,90) -now slowly turn C22 for 14914,50 readings (or 14914,90) -recall CAL PLL for TP1 on 40m band -recall CAL FIL for TP2 on each filter/mode. Now you can recheck your K2 on WWV at 10001,00 kHz, as a rule the error makes few Hz. Same pictures you can see if follow here (in russian): http://www.hamradio.cmw.ru/elecraft/calibrated.htm 73!

An AM station broadcasting standard and constant tones (such as WWV) is easiest because one can observe the demodulated audio tones with Spectrogram assuring accurate tuning. If you have a good ear, you may be able to tune to a station broadcasting music to within 5 or 10 Hz. If you do use an AM broadcast station without standard tones as your standard, I would suggest that you tune it by ear in LSB or USB first, then switch to CW while observing the audio with Spectrogram - the carrier should appear 'straight and tall' at the frequency you have set in the K2 for the sidetone pitch - thus assuring accurate tuning of the station. Then go back to SSB mode to set C22 while doing the subtraction between the VFO and BFO frequencies. A note to help - any adjustment of C22 will move the VFO frequency reading about 5 times faster than the BFO reading, so do the adjustment with the counter probe plugged into TP1 and then check the result in TP2. A few trials should yield an accurate setting. 73, Don W3FPR David Woolley wrote: Don Wilhelm wrote: refer to the K2 Dial Calibration article on my website http://w3fpr.qrpradio.com for techniques to accurately set the 4 MHz reference oscillator and the following steps to achieve good dial calibration.

[Elecraft] [K3] clarification on VFO and 2nd Rx
I seem to be very confused about the way VFOa and b control transmit and want to get some clarification please. I started (in 2004) with an Yaesu FT-857 and am still using that, the way it works may well have coloured my understanding. If I may, let me describe what I understand based on that: The 857 has 2 VFOs, A B and at any one time you can see the freq, mode etc set up on a specific VFO displayed, along with the VFO (id - a or b) that it is. If I press A/B, it switches from A to B and vice versa. If I have VFOa selected and Tx, it uses that freq mode etc to transmit. If I have VFOb selected and Tx, it uses the settings for VFOb to transmit. It also has A=B which is slightly confusing and wrong, because it actually copies VFOa to b - as the AB button on K3. A K3 without 2nd RX (KRX3) has 2 VFOs and each VFO can be set up to a specific frequency and mode, using certain roofing filters and DSP settings etc. You always listen and transmit using VFOa settings. To use the VFOb settings you must tap A/B, which swaps the settings between VFOa and VFOb, therefore meaning that VFOa is now using the settings that were on VFOb? And when you transmit, you're using those. When you do this, the TX and ^ (black arrow above TX) icons will show you as transmitting on VFOa? This is pretty much as per the FT-857, I just never thought of it in that way (I also think of the rig using different circuits to transmit, but I doubt now that it is). If you are working split, you transmit on the freq, mode etc., set up in VFOb - it uses VFOb for transmit. In this scenario, SPLIT, TX and v will be shown to indicate you are transmitting on VFOb? If you have the 2nd RX (KRX3) fitted and ON (SUB on), VFOb is used to control it. In other words, the KRX3 module does not have VFO circuits on it, it requires a VFO (B) to set it up etc. All the other rules above apply though? If the SUB is not on, its pretty much as first described? Can you even turn on the SUB if its not fitted and if you can, what happens? Finally, the [REV] button described on pg 15 as exchanging VFO a b temporarily - what does that mean - while you have it pressed it swaps and if you release, they go back? If so, while you have it pressed and you Tx, does if use VFOb settings?

[Elecraft] [K3] clarification on VFO and 2nd Rx
I'm unclear about VFOA/B functionality when using the main and subreceiver in diversity mode (i.e., tuned to same frequency) and the transmitter in split mode. It seems that the subrx needs to be assigned to VFOA in this case but I'm not sure if the K3 provides that flexibility (like the Orion). The manual attempts to address this specific case as follows, although I'm not getting it: Split Mode with the Sub receiver: When operating split, VFO A is the receive frequency and VFO B the transmit frequency. If the sub receiver is on, you'll be able to listen to both your receive and transmit frequencies in receive mode. Hold SPLIT to turn split mode on or off. Can someone explain what the manual is trying to say here and how VFOA/B is being assigned to the subrx in diversity/split? Is the subrx always assigned to VFOB or is there more flexibility than this?

Re: [Elecraft] [K3] clarification on VFO and 2nd Rx
You might have seen my post asking for clarification too. I'm pretty sure KRX3 will always use VFOb and can not be switched at present. My understanding is that with the sub on, its audio goes to the right channel of the stereo output and VFOa's audio goes to the left channel. That's regardless of SPLIT or not. So in a pile-up, you can here both the freq when the op is working split. In other situations, you might be calling on a fixed freq and listening for CQs on other freq.

[Elecraft] RE: CW: Best low cost iambic key
Rob; Define low cost The used Begalis go for about what a new. Used Benchers are fairly easy to find in various states of dis-repair. There are also the AzSqrpions paddle-kits that seem to have a solid look, I've been meaning to order one as a spare/travel paddle. If you don't mind fabrication and a lighter feel (though, since you're building it, you can tweak this) you could try one of the 10.00 Jackson Harbor touch paddles. Even though I have a Begali, and a Bencher, I've actually probably put more QSO's on my little JH Touch paddles since I spent a good part of the summer operating outside of my shack. They take a bit of getting used to, but, I built mine into a little box and used dimes for the contacts. I can hold the key in my lap and send. At times it's very comfortable. I've a used bencher that I enjoyed, but, while I don't have a heavy fist, I like a solid feel. I bought a Begali Simplex at Dayton; New they're within 10 or 20.00 of a new Bencher, but, I like my Begali a whole lot, and I've loaned it out to several local CW ops who have also enjoyed it. I'm pretty sure I'll end up with one of the magnetic units from Begali this year at Dayton. The craftsmanship is beautiful and the keys all feel great. There are several others, N3ZN, there is an K8 whose call I forget, all look to be substantial and they all seem to fall in the 100-200.00 price range. 73, Joe KC0VKN ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] [K3] clarification on VFO and 2nd Rx
David, It may help if you mentally divorce the physical VFOs from the A and B designations and think of the DISPLAYED frequencies. The main receiver will receive on whatever frequency is displayed on the VFO A readout, the sub-receiver (if installed) will receive on whatever frequency is displayed on VFO B. When SPLIT is active, the above conditions are still true. In SPLIT, transmit will take place on the frequency that is shown in the VFO B display. How you alter the frequencies between the VFO A and VFO B is the result of the button pushing. AB will make both VFOs the same - the contents of VFO A are copied into both VFOs. A/B will swap the contents between A and B. While you hold REV, the contents of A and B are swapped only until you release the button. In non-split operation, the A/B button will allow you to rapidly switch between two different transmit (and receive) frequencies. Normal SPLIT operation *might* proceed something like this: Tune to the frequency where you wish to transmit with VFO A (maybe you hear the station that the DX is currently working), then tap AB. Now tune so you hear the DX station (with VFO A). Press the REV button when you want to listen to your transmit frequency. You can alter your transmit frequency by holding the REV button and tune (with VFO A knob) or by tapping A/B to swap, then re-tune and tap A/B again to swap back. It works fine this way on the K2, but the K3 adds a separate knob for VFO B which will be helpful for refining the transmit frequency, especially when the sub-receiver is installed. With the sub-receiver installed, it becomes more flexible because the sub-receiver will be tuned to your SPLIT transmit frequency and you can listen to that frequency in one ear if you have that selected. There are a thousand other scenarios that are possible for split operation and perhaps others will offer their favorite operating patterns with it. 73, Don W3FPR David Ferrington, M0XDF wrote: I seem to be very confused about the way VFOa and b control transmit and want to get some clarification please.

Re: [Elecraft] [K3] clarification on VFO and 2nd Rx - erratum
David, I think the real answer to those extensions will have to wait until after the KRX3 ships.

RE: [Elecraft] CW: Best low cost iambic key?
Low cost - think used. Used is always a better bargain than new. I had Bencher BY-1 BY-2 paddles. Loved them until I tried a Kent. The Benchers are a bit squishy. The Kent is a very solid, very nice feeling paddle. I got mine of e-Bay for about $90. I see the Kents on e-bay from time to time so they are available used. That said, a used bencher is easy to come by and will be somewhere around $60 or maybe less. They're hard to beat at that price. I hear lots of good things about the Begali Simplex paddles as well, but again we're well over $100 for them. - Keith N1AS - - K2 5411.ssb.100 - - K3 wave 3 - ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] [K3] clarification on VFO and 2nd Rx
Don Wilhelm wrote: How you alter the frequencies between the VFO A and VFO B is the result of the button pushing. AB will make both VFOs the same - the contents of VFO A are copied into both VFOs. A/B will swap the contents between A and B. While you hold REV, the contents of A and B are swapped only until you release the button. In non-split operation, the A/B button will allow you to rapidly switch between two different transmit (and receive) frequencies. When the sub-receiver becomes available, there will also be a special mode which allows you to 'slave' both VFOs to the main tuning knob. This will permit true diversity reception, with separate antennas on each receiver. I am looking forward to trying this, perhaps with a vertical and horizontal antenna. Hopefully one signal will get stronger when the other QSBs! I don't know what Wayne plans for the audio. In the years of AM, diversity setups compared AVC (that's what AGC used to be called) voltages and switched to the best signal. Of course you could listen to the two antennas in separate ears, but it would be interesting to somehow combine the audio signals so you would get a (relatively) QSB-free result. -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] [K3] clarification on VFO and 2nd Rx
For years here at my place of employment we've offered UHF diversity receivers where, instead of switching between the two signals, we blend the audio outputs of the receivers in a ratio controlled by the RF level of the received signals in the two receiver sections. Once done using analog circuitry, we do it in the digital domain these days. We refer to it as ratio combining diversity.

[Elecraft] [K2] No RTTY Output
Hi Folks, I reported this problem back in the spring but didn't have time to act on it. Forgive me as I re-state the problem I'm having. I have a K2 equipped with Don Wilhelm's constant audio volume mod for digital operation (hope I described it correctly, Don). I also use a Tigertronics SL-1+ interface between my K2 and my notebook. In LSB mode I'm able to transmit RTTY and PSK-31 without any problems. When I change the K2 to RTTY mode I get no transmitter output (receive works fine). The PTT indicator on the SL-1+ lights and the K2 receiver mutes, but there's no RF output indicated on the K2's meter or an external power meter. Cables and connections are fine, and as I mentioned, simply switching to LSB gets me back on the air. I don't get on the air as frequently as I'd like, and at times sitting down with the K2 and using it is like starting over from scratch. So, there's a good possibility that something's not set correctly. However, so far I haven't found a setting that would disable RTTY output like that. Can anyone help?

Re: [Elecraft] [K2] No RTTY Output
Ken, First, investigate the filter settings for RTTY with Spectrogram. Be certain the FL1 positions are correct (use the OP1 filter and set the BFOs similar to those used for SSB FL1). You may set the RTTY FL2, FL3, FL4 filters any way you wish, but FL1 must be set to OP1 and the BFOs correct for that filter. The LSB settings (RTTY) will have the BFO positioned below the filter center frequency (typically the BFO frequency will be 4913.xx) and the USB BFO (RTTY-r) will be positioned above the crystal filter center (typical 4916.xx). The .xx part of the frequency will vary depending on the exact filter center frequency. Secondly, revisit the carrier balance adjustment on the KSB2 board - you can do that is SSB mode, but check using both LSB and USB - you may have to compromise a bit between the two. After doing the above, check the K2 on RTTY again - if you have audio frequency tones going into the mic connector, it should work just the same as for SSB - and on both sidebands. 73, Don W3FPR Ken Alexander wrote: Hi Folks, I reported this problem back in the spring but didn't have time to act on it.

There's another very inexpensive alternative not yet mentioned: touch key paddles. For my purposes, mostly ragchewing at 25-30 wpm, I actually prefer touch key paddles.

I use Jackson Harbor's touch switch (kit), $11.50, postage paid. http://home.att.net/~jacksonharbor/touchsw2.htm I put the circuit board in a Radio Shack project box with dimes, one on each side, as the touch contacts.

RE: [Elecraft] Have we gone Off Track?
Yea, I think we have. Or at least the list has shifted and isn't the same as it was. It is the K3's fault. Prior to the K3, we were all engaged in buying building K1, K2, KX1 and mini-module units. Now with the K3, I suspect most of us are on hold. We've ordered our K3 but are not ordering K1s, K2s, KX1s since we need that money to pay for the K3. My plans have changed. I was planning on a K1. Instead I'm in K3 limbo, waiting for my order to be filled. I was planning on the DSP for my K2 but no longer. K3 will do that. So with no building going on at my QTH there's nothing to talk about except K3 deliveries, iambic paddles, and silly blonde jokes. Will it ever come back? Once the K3 gets out there I bet you'll see a bunch of traffic about the assembly and operation of that rig. Eventually the K3 wave will subside somewhat and you'll see more K1/2/X1 posts in the mix. I bet it will take many months (years?) though. Of course, when Elecraft comes out with the KPA800 and KPA1500 kits, that will stir a bunch of kit building posts again. - Keith N1AS - - K2 5411.ssb.100 - - K3 Wave 3 - -Original Message- From: john-n4dsp This reflector used to be a Gold Mine for builders.

Re: [Elecraft] [K2] K2/100 - where does all the hot air go?
Stephen, The air exits just behind the front plate - through the fins of the heat sink. There is lots of exit area, no need to worry. As far as just how fast the fan comes on, that depends on the temperature (of the heat sink at the PA transistor locations). CAL TPA must be set in the menu should be set correctly, and set the FAN parameter of the PA ON menu item to NORMAL (tap DISPLAY to toggle the fan settings). Turning the power down will reduce the heating and delay the fan turn-on time G. 73, Don W3FPR Stephen Prior wrote: I have the 100W amp mounted in an EC2 enclosure, all working great now, no small thanks to Don! I have a question. The little fan on the back seems to push air into the unit, yet there is no obvious exit for it. Or am I missing something? Almost seems like I need an automatic vent popping up at the front (that little panel could lift) like the vent on the back of a Porsche! Perhaps replacing that little panel with a perforated one would help? I'm a little surprised at how quickly the fan comes on (on cw, I haven't used ssb yet), and also quite taken aback by its noise! 73 Stephen G4SJP ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] [K2] Problem with MH2 and K2/100
Hi, gang, I need your help. I just received a new MH2 mike from Elecraft and intend it for eventual use on my third round K3 order. In the meantime, I modified my K2 to use it -- the sheet included with the mike provided instructions for doing so and I added the resistor across pins 1 and 6 of the mike socket and use the header pins they provided. All went tickety-boo. I used to use an old Icom hand mic which worked very well but I was looking forward to being all Elecraft (I have an Elecraft Hexkey, too!) Well, darn if the thing is giving me trouble: it acts as if there's RF in the system but the mike socket is grounded and it even acts that way at low power; my watt meter shows approximately 40 watts of power when the mike key is depressed on LSB but -- get this -- no power is shown when it's on USB where it seems to work fine! What should I check? Help! Thanks... 73, Joe, W2RBA ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

In my defence of course, I can add that although I have the mic plugged in, it hasn't been used yet! Now that I have been prompted to look at it more closely, I can see where the air can escape, as you say on the edge of the heatsink. I think I shall go look on eBay for a quiet fan to sit on top as you have done. I'm using headphones 99% of the time, and I can even hear the noise of that little fan through those! It's rather like the Jack Russell dog we have here, small and noisy! Maybe I should be using the noise cancelling Sennheisers I bought for our trip to NZ this year, trouble is I hate to feel excluded from the sounds of the outside world (I might miss the offer of a coffee or something!).

Re: [Elecraft] [K2] Problem with MH2 and K2/100
Joe, I am not certain why the Elecraft mike would have that kind of problem and not the Icom mic. I have trouble believing it has anything to do with the particular mike. Get out the computer and Spectrogram (or similar tool) and check the position of the IF filter passband for both LSB and USB when in the FL1 filter position. If you have the 2.4 kHz wide SSB filter center the passband between Spectrogram markers set at 300 and 2600 Hz, if you have the older 2.1 kHz filter, use 300 and 2300 Hz, and if you have the wide 2.6 kHz filter use 300 and 2900 Hz markers. Note that the lower marker does not change - it should always be 300 Hz. Once the passband positions are correct, do the carrier balance adjustment. You can do it as instructed in the manual, or if you have a means of measuring small RF voltages (like with a 'scope), you can plug in a key (no mic connected), set for LSB then hold the dot side of the paddles (DOT and PTT are the same line inside the K2), and adjust the pot for minimum RF voltage. Check USB and if necessary, tweak the balance pot for a compromise between LSB and USB. After those adjustments are complete, check the mic operation again. If you still have trouble, you may want to check for 'RF in the shack' (but I would think that should be a problem with both sidebands). 73, Don W3FPR jmalloy wrote: Hi, gang, I need your help.

Hmmm ... the list has changed some, but you're right, the K3 both upped the volume of postings just a little :-) and the fact that no one is building them yet may have led to a bit more idle chatter, maybe out of boredom waiting, although if that's the case, some folks may have too much idle time on their hands ;-) Honestly however, I see lots of non-K3 Elecraft product and building questions, all answered by the usual suspects [we all know who they are, don't we]. I've also found this list to be a great source of info about related stuff ... like the recent question about keyer paddle options, likes, and dislikes, and the huge number of responses.

Used Benchers are fairly easy to find in various states of dis-repair. There are also the AzSqrpions paddle-kits that seem to have a solid look, I've been meaning to order one as a spare/travel paddle. If you don't mind fabrication and a lighter feel (though, since you're building it, you can tweak this) you could try one of the 10.00 Jackson Harbor touch paddles. Even though I have a Begali, and a Bencher, I've actually probably put more QSO's on my little JH Touch paddles since I spent a good part of the summer operating outside of my shack. They take a bit of getting used to, but, I built mine into a little box and used dimes for the contacts. I can hold the key in my lap and send. At times it's very comfortable. I've a used bencher that I enjoyed, but, while I don't have a heavy fist, I like a solid feel. I bought a Begali Simplex at Dayton; New they're within 10 or 20.00 of a new Bencher, but, I like my Begali a whole lot, and I've loaned it out to several local CW ops who have also enjoyed it. I'm pretty sure I'll end up with one of the magnetic units from Begali this year at Dayton. The craftsmanship is beautiful and the keys all feel great. There are several others, N3ZN, there is an K8 whose call I forget, all look to be substantial and they all seem to fall in the 100-200.00 price range. 73, Joe KC0VKN ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Thanks, Don. HHmmm...now I wish I could have built my K2. I'd have a better idea of what you're talking about. This sounds like a project for Saturday afternoon. I read through the SSB adapter manual this afternoon, so it's not as intimidating sounding as I first thought. Nevertheless, I'll make sure my fridge is full of beer before I start on this! 73 - Ken --- Don Wilhelm [EMAIL PROTECTED] wrote: Ken, First, investigate the filter settings for RTTY with Spectrogram. Be certain the FL1 positions are correct (use the OP1 filter and set the BFOs similar to those used for SSB FL1). You may set the RTTY FL2, FL3, FL4 filters any way you wish, but FL1 must be set to OP1 and the BFOs correct for that filter. The LSB settings (RTTY) will have the BFO positioned below the filter center frequency (typically the BFO frequency will be 4913.xx) and the USB BFO (RTTY-r) will be positioned above the crystal filter center (typical 4916.xx). The .xx part of the frequency will vary depending on the exact filter center frequency. Secondly, revisit the carrier balance adjustment on the KSB2 board - you can do that is SSB mode, but check using both LSB and USB - you may have to compromise a bit between the two. After doing the above, check the K2 on RTTY again - if you have audio frequency tones going into the mic connector, it should work just the same as for SSB - and on both sidebands. 73, Don W3FPR Ken Alexander wrote: Hi Folks, I reported this problem back in the spring but didn't have time to act on it.

The PTT indicator on the SL-1+ lights and the K2 receiver mutes, but there's no RF output indicated on the K2's meter or an external power meter.

Re: [Elecraft] [K3] Wine Update Software
There is a huge difference between the old battery-backed memory and using Flash memory. As you note, the battery will eventually run down, causing memory to be lost. Flash memory will retain its contents for a very long period - Microchip specifies this at 40 years minimum, 100 years typical. This is actually comparable to the EPROM memory in the One-Time Programmable chips used in the K2, and much longer than anything backed by battery. Parameters in the chips are stored in EEPROM memory, which also is specified at 40 years minimum, also much longer than the battery-backed systems. I seriously doubt you will ever see the chip die from memory loss. More likely the reason you would want to reprogram it will be to gain new features as Wayne releases them. This is true whether the radio is a K3, K2, K1, KX1 or anything else that Elecraft might dream up. On Oct 15, 2007, at 10:40 PM, Leigh L.

My concern is that eventually, there will be a need to reload the K3's firmware, and the version of Windows it's for might not be there. Think of the timescale of ham radio vs. the timescale of Windows releases. There are Japanese ham radios from the 1980's which are now bricked because config memory settings were lost when the battery went dead. It's not important right now, but eventually, having an open way to reload the firmware will be important. That's not the same as saying that the firmware itself needs to be open; it just should be possible to restore the radio to it's original state without having to find a 20 or 30 year old laptop. The K2 doesn't have this problem because its firmware isn't writable. 73, Leigh/WA5ZNU David Wilburn wrote: A recent thread mentioned update options, but I did not see any new news. Has anyone tried the K3 update software using Wine under Linux? ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

As you note, the battery will eventually run down, causing memory to be lost. Flash memory will retain its contents for a very long period - Microchip specifies this at 40 years minimum, 100 years typical. But, they don't know that as a fact, and make lots of assumptions when making those claims. The chips have obviously not been around over 100 years to make that claim true. Ask Microchip if they will stand behind those claims, and provide you with replacement chips in 39 years if the flash memory fails at that time. I seriously doubt you will ever see the chip die from memory loss. Well, I can tell you that the Motorola microcontroller in my (and many others') Audi instrument cluster died due to failed flash memory, and after only a couple of years, not the 40-100 years the manufacturers guess and hope they will be good for. Motorola shipped a batch of bad chips. Firmware files are not available from anywhere, and Audi charges $800+ for a replacement, even though I have the ability to program a $20 chip myself. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
