Re: [Elecraft] 43 Ft Vertical and Elecraft Tuners
Definitely a loaded question. No pun intended. I don't have any experience with 43 ft verticals myself but have heard a lot about them and have been thinking about building one. I too would like to learn more.

I'd like to know of any stations using a 43 Ft vertical as a multi-band antenna using nothing but an Elecraft antenna tuner for matching -- that is, no "baluns", transformers, loading coils, or additional matching networks. I'd like to know the bands on which you are able to match it well enough to get full power from the rig (or the power amp). I'd like to know if the tuner is located at the base of the antenna, or, if in the shack, the length of feedline between antenna and tuner.

Re: [Elecraft] Firmware
It's always a good time for new and/or improved features. Did you have anything particular in mind?

[Elecraft] W2 firmware anomaly
Good afternoon all. Today I decided to dust of my W2 and put it back in service but had something odd happen after updating the firmware (from 0.94 to 1.00) and was wondering if anyone else had seen this. The firmware load went fine and afterward everything was working great except for adjustment of the SWR alarm trip point. Sending the [ and ] commands with the W2 Utility always resulted in a response of [00; or ]00; regardless of how many times they were sent. This happened whether or not the alarm function was enabled or a sensor was connected to the W2. I also tried powering it off then back on, restarting the W2 utility, etc. with no changes. All other commands worked as expected. My computer (Windows 7) doesn't have a real serial port so I'm using the KUSB cable with FTDI chipset which has never given me any trouble. I noticed that firmware v0.94 did not have this capability and I had never used the alarm function before anyhow. Maybe that had something to do with it? I finally thought that maybe a plug had to be in the 'REM' jack on the back of the unit for the alarm function to respond so I tried that. The first reponse was again [00; but after that it came back with [50; indicating it was set for 5.0 and it started working as it should. I was then able to vary the trip point up and down (from 1.2 to 5.0) and get the response I expected. After that I tried removing the cable and it kept working, power cycling the unit (including turning off the power supply it was connected to) with and without the cable and it kept working. It seems to be fine now, so I'm not sure what I did or didn't do. I built the W2 from the "kit" if that matters, but it has always worked great excluding this. Thanks for your input.

Re: [Elecraft] {K-3} K144XV
It sounds like the sub can be on 2m, but only if the main is as well and they are sharing the KXV3A input path. In that case the main and sub could be on different 2m frequencies, but must both use the antenna connected to the K144XV. Unless something hasn't been implemented yet.

Re: [Elecraft] {K-3} K144XV
My last attempt didn't make it through, hopefully this one will. Hi all, As I understand it, the only input path to the K144XV is it's dedicated "ANT 3" BNC connector, it cannot receive signals through the ATU. The only way the sub receiver can listen to it is if it is sharing the main receiver's antenna connection and hearing the 28MHz IF through the KXV3A. Otherwise 2 K144XVs would be required. The sub receiver can be set to "MAIN" to share the main receiver's signal or "AUX" which depending on how it was hooked up when installed will either be the non-transmitting jack on the ATU (CONFIG:KRX3 set to ANT=ATU) or the AUX RF BNC connector on the rear panel (CONFIG:KRX3 set to ANT=BNC), neither of which will hear the K144XV. With the sub turned on go into BSET and tap ANT to change it's antenna to "MAIN." Holding RX ANT will also change the sub's antenna when not in BSET. Thus, 2M diversity reception is not possible with the K144XV. I have the sub RX but don't have the K144XV yet (it should arrive any day), so I could be missing something, but I have been studying the manuals in preparation. I'm sure someone will correct me if I'm wrong. Hope that helps.
