Re: [Elecraft] hooking up a K3 to a Alpha 76
Over the years I have had numerous faux paux with RCA plug cables. Two favorites are 1) the shell doesn't really connect with sides of the mating jack. 2) The pin is not long enough to contact inside the jack. This can be due to short pin, or some detail of the plug shell/jack combo not allowing sufficient insertion. The stories associated would make a small book. 73, Guy K2AV -- View this message in context: http://elecraft.365791.n2.nabble.com/hooking-up-a-K3-to-a-Alpha-76-tp7574001p7576272.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] dBi dBd correction
The way the regulation reads, hams are being told they can put 50 watts PEP on an antenna, up to the gain of a dipole, and call that 50 watts ERP. Higher gain must be referenced to the dipole and the 50 watts reduced accordingly. For mobile stations there is no mention of the idea that a LESSER antenna may have the 50 watts increased. 100 watts appears to be in excess of regulation. Stated another way, 50 watts max regardless, unless the antenna has more gain than a dipole in which case power must be reduced by a factor representing the gain of that antenna over a dipole. The whole thing is really interesting since there are really precise definitions of ERP elsewhere in FCC referencia. By the regular definition of ERP 50 watts into a dipole for 5.3 MHz at 108 feet over medium ground will have an ERP of 328 watts. At 50 feet the ERP is roughly 200 watts. We had best be very careful with our privileges on 60m, because all FCC would have to do is enforce regular definition of ERP and the same dipole at 108' would take seven and a half watts to obtain 50 ERP at pattern max. 73, Guy It may also be that whoever wrote the reg was having a brain f**t at the time, and they just haven't discovered it yet.

Re: [Elecraft] dBi dBd correction

Where did you get that interpretation?

The math is fairly straightforward. You must reduce your power by the number of decibels your antenna gain exceeds 0 dBd (0 dB relative to a half-wave dipole). Conversely, you can increase your transmitter power if your antenna exhibits loss compared to a dipole.

Re: [Elecraft] Filter Selection Approach
Casual operation has rarely strained my radios, and my MP and my K2 are quite adequate for that. When we get to contesting, all facilities are strained. I prefer the K2 audio to the K3, and sometime soon I will get to the bottom of that. The quickest, sharpest, deepest skirts on selectivity still belong to my MP with matched 8 pole INRAD filters in 8 Mhz and 455 kHz IF's. (I know that's heresy, but so be it...) On receiver front-end, overload immunity and SDR-driven DSP magic (like blanking key clicks), with more to come, the K3 leaves everything else in the dust. But I pick roofing filters to get as close as I can to the MP+INRAD+INRAD skirt performance. BOTH K3 selectivities (roofing and DSP) need to be matched to produce optimal rejection of signals just outside of the desired listening window. I have the 400 and 250 8 poles in my K3 and list them as 450 and 350 in the filter setup. The bulk of my operation in a contest is RUNNING, not search and pounce, for DX tests mostly using a very large 40m antenna fixed on Europe, and with huge differentials (80+ db) between desired weak signals and undesired strong signals just above and below. I also specifically use the [sometimes complained about] mild difference between the two to advantage, as I use BOTH for running, and use 350/300 when I need it just a bit tighter. While I could narrow down with a 5 pole 200 on a weak station, 1/3 or more of the stations calling are off my frequency, often because the current packet spot is up or down. And I'm not allowed to spot myself to fix it. I have to keep a window to hear them or someone else gets the top score. The next CW station can be up/down only 350 Hz, meaning that outside the listening window, the skirt needs to dive for ultimate rejection as fast as possible. Being flat at +/- 175 is not the issue when setting at 350 width, it's how far down the combination of skirts has gone at +/- 225. The most important thing is where are the skirts halfway down and how much more do they drop with another 10 Hz, NOT the 3 db or 6 db points. The 8 pole roofers are part of making those skirts dive more in 10 Hz halfway down. I set up my filters at the +/- 50 dB points, and eagerly await the day when CW widths and shifts are in 10 Hz increments. I have had some extremely vociferous contradictions from some insisting that the 8 pole roofers are simply a waste, and a wide and narrow 5 pole are all needed, but my contest experience continues to suggest otherwise. All of the above are in stark contrast to casual operation. Buy filters for how you use the radio. If you are into hard contesting, do it with 8 poles. 73, Guy K2AV -- View this message in context: http://n2.nabble.com/Filter-Selection-Approach-tp2630347p2639610.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] K3: The ARRL RTTY Round UP
Changing SHIFT and WIDTH granularity to 10 Hz from 50 would improve CW useability as well. A lot of us have formed contest operating habits and tactics based on analog SHIFT and WIDTH functions.

In recent revisions, VFO A still controls both synthesizers, but VFO B is left independent so it can be used for SPLIT with diversity (i.e., as the transmit frequency). You'll also notice that in diversity mode, the VFO A kHz decimal point flashes as a reminder. If you link the VFOs (normal hold of SUB), the VFO B kHz decimal point flashes. In fact you can still link VFO B to VFO A if desired, even in diversity mode, but more likely you'll leave VFO B free to use for split. One other change in the most recent revision is that PRE and ATTN are independent for the main and sub receivers.

Re: [Elecraft] Bigger K3 S-meter
I'd like to be able to calibrate it to 1 uV and 50 uV and know that the noise on the band is -10 or +3 dBuV and that the signal from a friend has gone down to +18 from +26 last week and previous. That requires a calibration, and while one could just use what the rig does naturally as a reference, the K3 has changing SDR code, and maintaining a calibration on a reference source sure does simplify things. To another objection earlier in the thread, inexpensive test equipment doesn't have selectability to narrow down on a single CW signal. So I'm looking at the firmware only abilities (not hardware) of a K3 to do something that has always been a bear.

Changing the functionality of the BG or SM commands so they could provide greater resolution *would* break software, which is what I was saying. But while I can see that having software access to the dBm reading could be useful for antenna measurement purposes, given the vagaries of propagation I would have thought that a 1 S-unit resolution was perfectly adequate for normal purposes. I cannot see how it would be more useful to be told I am S6.5 rather than S6 or S7, or even S5 or S8!

Re: [Elecraft] K3 - interfacing to N1MM Contest Logging software

Re: [Elecraft] AGC behaviour
With the new firmware, I found it necessary to do the S-meter calibration. This restored the previous base behavior. Not sure what the state was before the calibration, whether I had done the prior calibration correctly, etc., so I can't blame the firmware. My guess, though, is that I'm on a learning curve, and only the latest, most informed thing I have done can be trusted, if that. Afterwards, if your noise goes from S nothing to S5 by attaching the antenna, you surely are in a noisy locaton. If so, turn off the preamp and/or use the atten to reduce the resting gain of your RX. After that just turn your RF gain counter clockwise until the resting noise in the RX is something you can live with. I've had to do that all summer long, as 40 and 80 meters have had nasty QRN nearly continuously. Beyond that, reducing bandwidth on CW, the K3 has been able to listen down into the noise in a way unrivaled by any other RX I've used, including the Orion. Of late for CW QSO's, once established, I center their signal, and go to 50 Hz bandwidth immediately. No reason not to, and the bandwidth drops the noise way down. If they are above the noise, tuning just barely slightly off their signal removes just enough softness in the signal to make it quite pleasant. 73, Guy. My K3 #1263 was delivered in July with F/W MCU 2.18 DSP 1.84 and I was really enjoying the RX capabilities of the K3. Now that I have upgraded to 2.38/1.90 I believe the RX is more restless when listening to an empty space on the band. The S-meter is constantly on S5 with pre-amp ON and S3 with pre-amp OFF on the lower bands (30/40m). I have compensated that a bit by lowering the AGC threshold (from 5 to 4 now). I liked the initial F/W wrt AGC behavior better (less fatiguing to listen to). I have read in the F/W history file that changes to the AGC have been made from F/W 2.22 onwards. So I wonder if other people have the same experience. I live in an urban area so it IS noisy out here. It is just the way the K3 deals with that noisy background level. When switching to ANT2 (not connected to anything) the RX goes virtually silent. -- Enno, PF5X -- View this message in context: http://n2.nabble.com/AGC-behaviour-tp1114728p1115351.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Hearing the effect of narrower roofing filter
. Maybe I should have ordered the 200 Hz 5-pole instead, but I got it into my head that maybe the 8-pole filters were better in some way. I didn't repeat this mistake when I ordered filters for the subreceiver. Dick, K6KR I know I will incur some religious wrath from some however here is the OTHER side of that argument. It's not that I am denying the issues that are raised to question getting the two 8 pole CW filters (400 and 300 in actuality). I am solving a SINGLE happenstance which occurs over, over, over and over again in contests, so much so that until the K3 it was in my mind the LIMITING issue in improving 40m CW DX scores. I am at a contest station in eastern NC just off Pamlico Sound. On 40m to Europe we are using a 5 element wire quad suspended across a 220 foot NE/SW catenary between two towers. Broadcast signals above 7.1 routinely peg meters and light all the lights. So do some US stations in the NE, and so do some number of VERY LOUD European stations (VLS). WHAT they are doing to be so loud is not part of my exposition. They just are very loud. At some point in the contest, one has worked all the VLS, loud, medium and well-antenna'd QRP signals. What remains is a bewildering and seemingly bottomless pool of stations that can hear us (QRO on 5 elements) and are trying to work us on antennas with the gain of a basement floor joist wet noodle antenna. There are hundreds and hundreds of these. We have some number of recordings made in Europe of these, and they are quite weak over there. It is guaranteed, only a matter of time, and sometimes immediate, that a VLS will settle in the next slot above or below. They may be as close as 350 Hz. The problem now is working the QRP wet noodle station who is into the noise without hardware AGC pumping or other effects from a VLS INSIDE the roofing filter that was set to hear stations who will call sometimes +/- 200-250 Hz. I need the roofing filter is to get down 30 db as quickly as possible, without giving up too much of the +/- 250 Hz. The 400 Hz is a good width even for VLS +/- 500 Hz. If a VLS squeezes me on one side, I only want to give up +/- real estate in the roofing filter on that side. The procedure is to drop to 300 hz roofing and DSP and move the RX center 50 hz away from TX frequency and the VLS. I give up listening so far on the side of the VLS, but keep the real estate on the other side. It is a matter of the width out to the edge and the largest db drop per 10 hz in the skirts thereafter. The roofing filter keeps the VLS from getting into the hardware AGC or pushing the DSP to the extreme. I have used both of these filters for years in my FT1000MP and am completely familiar with their shape and use in a contest. I have heard it said that the 200 5 pole filter will do better for picking out signals in a very crowded situation, perhaps so in an extremely tight situation. But thus far I have been able to go narrow with the 300 8 pole and it is the DSP handling the work there. At some point I would like to be able to tune the center of the DSP CW selectivity up/down at 25 Hz rate using RIT *WITHOUT* moving the position of the roofing filter relative to the band. The point of the roofing filter is to reject the VLS in the next slot above and below me. Tune the whole thing up or down to listen to a weak station off-frequency for whatever reason and you let one of the VLS in under the roof. Just the view from the other side of the river... :) 73, Guy. -- View this message in context: http://n2.nabble.com/Hearing-the-effect-of-narrower-roofing-filter-tp470635p795536.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] Hearing the effect of narrower roofing filter
I have used both of these filters for years in my FT1000MP and am completely familiar with their shape and use in a contest. The 250 Hz filters in an FT1000MP is an entirely different situation. In the FT-1000D/FT-1000MP, there are two filters - each approximately 350 Hz wide - in cascade yielding a composite 250 Hz (at -6dB) bandwidth. In my MP, having INRAD pairs at 400 and 250, one often used tactic was leaving the 455 IF at 400 (500 on the panel) and switching in the 250 in the 2nd If, to deal with a VLS squeezing in from above or below. Though it was certainly useful, the other cr*p being generated by the IF in the MP prevented making best use of the filters. I don't expect anything else roofing wise from them in the K3. The mere 100 Hz difference in the two is enough to deal with a squeezing-in VLS I already had compared the K3 website curves with my measured MP curves on the two filters with the 455 IF set wide, so I knew exactly what I was getting. In the WAE, this setup performed spendidly as expected. I had dsp width set to get the wider CW filter at 500 Hz dsp, narrower CW filter at 300 dsp. That's why *I* bought the two, with my eyes wide open, I make no claims to have the fully portable mantra for everyone to follow, just a view from another perspective. 73, and even if your mileage may vary may it still take you where you want to be.

Re: [Elecraft] Firmware and DSP Upgrades

Bob, K9PAG With all due respect, and perhaps a bit too blunt, BETA is BETA. The OFFICIAL (production) release has not changed since I received my K3. If you are averse to risk and finding a bug, then just don't do beta. Otherwise join the fray and find out what it's like to have responsive programmers, and half a thousand field testers working on beta releases (and KNOWING they are beta releases). I've been in the software business for four decades and do not perceive the Elecraft procedures as substandard, or lacking in procedure. Only in the government and regulated monopolies (read the old Bell System) or life-dependent products can one get away with testing something for four years before commercial release.

Re: [Elecraft] K3 Stopped Transmitting
I've had the same problem with #1239. I have made some observations about it. 1) It does not involve the KPA3. 2) The behavior is as if the power had been set to 0.0 by a program bug. Cannot hear the carrier externally on CW -- when it's working I CAN hear the carrier with power set to 0.1 w on the K2 setting next to it. When it's working and I set power to 0.0 I do NOT hear the carrier on K2 setting next to it. When power is at 0.0 I still hear some VERY low level phase noise or keying artifacts. When the trouble is in effect, I still hear the keying artifacts. I have several times caused the power to return by simply putting the rig in TUNE and leaving it there. It will come back to power over a long interval (5 minutes?) in a very jerky manner and suddenly kick in at 100 watts from somewhere in the 5-6-7-8 watt range. Idea here was to burn it in or burn it out. But neither happens, and it happens semi-randomly -- Seems to happen mostly when turning it on after cooling off overnight. Could this really be an ALC bug? Is there a diagnostic we can run, or a test procedure to further isolate this trouble? Would really love to solve this before the contest season. Guy.

Re: [Elecraft] K3-100 #1433: K3 ATU MALFUNCTION
Observations on KAT3 in #1239 Does not always set to 1:1 (think that is to be expected, particularly if close to 1:1 in bypass -- it has discrete values to switch in and out, not continuously variable components like my ATR-30) Sometimes it will not get started. This is usually someplace where the bypass SWR is high, like 2.5. It goes through the fast relay cycle, but does not fasten on a solution. In one of these situations, if I QSY to a place where SWR is lower and retry, it will solve it, and I can get to the original frequency it would not solve with two or three intermediate solutions. So it's NOT that it DOESN'T have the range, it's just not finding it in the solve if the reach is too far. I don't know of a way to place these solutions in memory (as in the MP) or if it is supposed to be doing that or if that is planned. At the moment the KAT in the K2 has it beat badly on smarts and match range. 73, Guy. Jack Regan-2 wrote: Greetings to all, Here is the text of a note I sent to k3support.

Re: [Elecraft] K3: Voice pitch adjustment on SSB
One thing I seem to be noting more and more on SSB, that operators are tuning up on the zeros and the rigs are good enough to put that within a few cycles. For tuning around on SSB, I've gone to the practice of setting freq display to .000, holding COARSE, setting it to 100 hz steps and tuning through the phone band. Surprising how many (most?) sound clear at some .0 that way. A few Hz one way or another won't make much difference. Spot on net frequencies don't require transmitting any tones. Let everyone with the accuracy transmit and receive on the zeros. Let the others zero in. The reason this was done differently in the old days was that people did not have rigs that would set or stay accurately on a frequency. So everyone would do their best to zero the NCS. Both my MP and K3 come up dead on WWV every time all the time. To listen to Yankees on WCBS radio (not always easy from NC), I set dial to 880.000 and listen up or down ESSB using 6Khz roofing filter. I can do the same thing to listen to music on Radio Moscow on 7125.000. 73, Guy O. Johns wrote: Folks, I read the web pages about ESSB, after seeing on the reflector that the K3 now supports it. It struck me that even ESSB doesn't solve one big issue with voice transmission: PITCH. Tuning the SSB receiver changes the overall pitch of the received voice. Unless you have met the sending ham or at least talked to him/her on the phone (or on AM!!), you have no real idea how high- or low-pitched the voice really is. One can only guess, and get a sort of feel for what a reasonable tuning is. One way to solve this may seem a joke, but it isn't. Everyone should buy a little 440 Hz pitch pipe, the kind used to tune musical instruments. Then, say, the net control could blow his pitch pipe at the start of the net and all the listeners could blow their little pitch pipes while listening to net control. They would all then adjust their receiver tunings until the pitches matched. Like a shortwave orchestra tuning up. (Of course, this might violate the FCC rule against music on ham radio, but maybe not if the pitch pipe was near a pure sine wave. Then the signal transmitted by net control would be just an ordinary CW signal, but at 440 Hz from the net control's suppressed carrier.) A refinement would be to build a pure 440 Hz tone generator into the microphone preamps of radios. Net control pushes a button while transmitting and it goes out over the air. The net members push another button while receiving to produce a 440 Hz tone in their speakers along with the received signal from net control. Then the receiving operators adjust their receiver tuning until the pitches coincide. For the tone challenged among us, the receiver tuning could even be automated, much like the K3 already does for sidetone on CW. This scheme came to me when I was adjusting the audio parameters on my K2. I had the K2 running into a dummy load, and was listening to it on headphones plugged into a TenTec RX320D across the room. Since the K2 was on a dummy load, I tried whistling and was surprised and pleased to find that the PITCH of my whistle didn't match the one I was hearing on the phones. But I could adjust the RX320D tuning until they did match. Guarantee of zero beat and realistic pitch in voice reception. Doesn't seem that this would be too hard to do. Maybe the K3 could even do it in firmware? 73, Oliver Johns W6ODJ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] K3: anticipated date for next normal FW update?
Something from my other existence, Field Validator's Release or Early Adopter's Release. One testing function is a methodical sweep for introduced bugs which includes regression testing for undoing of earlier fixes. The other major testing function is to operate all normal customer uses in the field with an eye out for problems and reporting such. The latter is termed field validation where I work, undertaken by customers who have some stake in early adoption and understand they may find stuff. The key to that kind of a developer/customer relationship is a speedy and serious turnaround on anything found.

Re: [Elecraft] K3-100 #1433 Will not transmit on 40 meters LSB.
Do you have power per band set in your configuration? If so you may not have advanced the power on 40m. Simply turn the power knob on 40m and make sure you have it set to your desired value. The first time I turned that option on, all of the bands defaulted to some very low level (0.5?). It's very handy for setting amp drive levels that vary per band so I don't need to use ALC or worry about it as I change bands. 73, Guy. Jack Regan-2 wrote: The rig works well on all the USB bands.

Re: [Elecraft] K3: S meter calibration
I'll worry about that when Wayne company quit hearing, accepting reports, and integrating suggestions. 73, Guy. That's not a good line of logic. It's along the same lines of: Your country: Love it or Leave It!!!.

Re: [Elecraft] K3: S meter calibration
To the issue, I would think that the hardware AGC intercept (and doing the mod) should strictly be a performance issue set by Elecraft for engineering reasons, and that the neat *option* to do S-meter calibration would be to set S9 and the other major points (S1/3/5/7 and +20/40/60) by raising or lowering calibrated signal with attenuator and let the firmware map it. Yeah, yeah, I know, put it on the list... As to ... Mine is like that and I don't appreciate it very much. I think Elecraft is putting out an affordable breakthrough product, AND amazingly managing to refine it further as they go. In the past I've had to put up with a truculent company who insists their engineers are gods and never make mistakes, and fixes mistakes in firmware under cover of darkness in the next improved design five years later and then charges new equipment prices plus for it. On the other hand, I've watched Elecraft evolve a portable QRP rig (K2) into a contest-worthy DSP rig that you can put a battery into and carry around, tromping receiver performance of rigs costing ten times as much. And then leverage that experience into a rig (K3) that has knocked every other manufacturer on their butt. In this and other postings, we all need to remember that what Wayne company are being whipped for daily is to put the boxes in shipment. AND that there is hardly anything else like the K3 around. Everyone has the choice to put their money with TenTec, Yaesu, Kenwood, etc. if they want to. Don't like the neighborhood? Move. I notice that the few K3's posted for sale on this list sold VERY fast at asking price. 73, Guy K2 #1239 K3 #1239 -- View this message in context: http://n2.nabble.com/K3%3A-S-meter-calibration-tp579287p579671.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3: REF CAL does not change for TCXO3 alignment
K3 alignment in user manual: Method 3 (1 ppm TCXO Option): • Locate the CONFIG:REF CAL menu entry. Tap 1 to change the name to REF xxC. • Locate the calibration data sheet, which shows frequency vs. temperature over a wide range. • For each data point, tap 2 or 3 to select the calibration temperature, then use VFO A to set the specified oscillator frequency in Hz. • Tap MENU to exit the menu. I have the TCXO3 and the little sheet with the calibration settings. Unable to enter settings because tapping 1 doesn't do anything in config. REF CAL will not change to REF xxC. The 1 button works for all normal RX functions. I have Firmware 2.11 which came with #1239. I am doing config in the technical mode. Tapping the 1 button in config mode briefly points to B VFO, as if that function was still in effect in config. Any clues as to what I may be doing wrong? -- View this message in context: http://n2.nabble.com/K3%3A-REF-CAL-does-not-change-for-TCXO3-alignment-tp577109p577109.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] K3: 2.1 vs 1.8
Engineering is *always* about compromises. -- Ron AC7AC While I certainly agree in theory, I don't think I'm making many with the K3. I picked my roofing filters on the basis of contesting and non-contesting. For non-contesting there's very little that strains the DSP. For general puttering about with 800-1000 hz CW, the 1.8 roofing is good enough. DSP does it. For puttering SSB, the 5 pole 2.7 does it. For SSB contesting, started with stock in the MP, then 2.1 INRAD's, and finally 1.8 INRAD's. So it's 1.8 in the K3, been there, done that. I never use the 1.8 in puttering mode, I use 1.8 exclusively in contests. For CW contesting, I go on the basis that there is an S9+40 station up 500 hz. I set my roofing filter to the width I want to hear and the DSP to match (400 for running and 250 for SP). With a 5 element 40m quad on Europe out at NY4A, and certain Europeans running plentiful power plus yagis, S9+40 up 500 hz is common past experience, not conjecture. BC carriers are often off scale. In the K3 the 400 clearly whacks down the S9+40 up 500 down to a DSP manageable value. To wit: At home (not NY4A) I was listening to a 40 over BC signal on 7125 last night with the K3 on 8 pole 400. Even turning on the preamp (carrier 60 over tuned in), tuned up and down 500 hz I could hear right down to S3 ish noise on speech breaks with fast AGC on. I could also hear their buzzy 120 hz harmonic residuals (100 db below carrier?) between QRN peaks. All that with no ringing. MP can't get anywhere near that using 2nd and 3rd IF INRAD 400's. Thas what I need. I didn't notice any compromises running around anywhere. Also, FWIW, when I added DSP to my K2's A-B mods it really improved performance. K2 sounds a bunch more like the K3 than the MP, either way you read that sentence. 73, Guy K2, K3 #1239 -- View this message in context: http://n2.nabble.com/K3%3A-2.1-vs-1.8-tp474969p527703.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
