Good Evening,
Twenty meters had more QSB while forty meters had less noise. No
snow was reported but there was rain and cooling. It is less foggy
today, not nearly gloomy enough for the Addams family.

W0CZ - Ken - ND
K0DTJ - Brian - CA
WJ7S - John - UT
K4JPN - Steve - GA

[Elecraft] Elecraft 80M SSB Net Report
3806 kHz (we moved up to 3808 kHz this evening, due to another conversation on 3805 kHz) 9PM ET Sunday (0200Z Monday).

Most signals were good all around, except those that were running barefoot. My S& to S8 noise floor on 80M here makes it all but impossible to hear those stations. Many thanks to the relay stations for pulling those stations in and making them part of the net. Very nice hearing from the new check ins and hope to see all of you again. The net concluded at 9:51 PM ET. In spite of the recent frequency change, the turnout was very encouraging. Hope to see you next week! 73, -- Dave, N8SBE __ 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] Elecraft 80M SSB Net Announcement
Dave- Typo in Frequency - should br 3.808 not 3.806 KHZ. Found the Elecraft new on Net Logger after poking around. 73, Kevin Robertson KD2WCY > On Nov 12, 2023, at 1:30 PM, Dave New, N8SBE wrote: > > Please join us on 3806kHz (NOTE NOTE NOTE THE NEW FREQUENCY WHICH MOVES US > INTO THE GENERAL CLASS BAND), 9PM ET Sunday (0200Z Monday).

Re: [Elecraft] K3 low temperature VFO tuning oddity - clicking relay
I'll be interested to hear what you learn, Mike. I don't have an ATU in my K-3, but I feed a KPA-1500, and when I QSY quickly (for example when pouncing on spots), I hear relays click in the amp's ATU. I assume this is a function of QSYing from one ATU zone to another, every 10 or 20 KHZ (except on 10M, where it's 100). It does this whether I'm transmitting or not. I wonder if the firmware update you installed added this behavior to your K-3. I can see where it might be a good thing to adjust the ATU before you transmit, even if just a few milliseconds before. 73, Pete N4ZR On 11/12/2023 2:59 PM, Michael Carter via Elecraft wrote: I've been getting reacquainted with my K3 (S/N 67XX) since adding the 100 watt PA module (KPA3A) last weekend. I also updated the firmware to the latest versions and ran the TX Gain Calibration successfully at all three power levels. The K3/10 had been sitting disconnected from everything since maybe 2019 when I used it to test the XV432 transverter I built. In operating in the early mornings this past week I observed an odd clicking of a relay as I tuned VFO A. Additional experimentation revealed that VFO B would also produce the sporadic relay clicking while tuning that control. There was no apparent pattern to the clicking, i.e. no regular frequency interval at which clicks occurred. In both instances the relay clicking disappeared after a brief warm-up period. I confirmed this behavior again by leaving the shack heat off and the rig off for a couple hours. The Front Panel temperature and PA Temperature both registered 12C on a cold start (yes, it is New Hampshire on a fall day), and the anomalous relay clicking on tuning either VFO A or VFO B ceased once the Front Panel temperature rose above 17C. This behavior was never observed in many years of operating the K3/10 in contests and general DXing, and the shack was plenty cold through those fall and winter mornings until the heat kicked up. I'll open the top cover and determine which relay is being activated during the cold start-up. Both VFO encoders go directly to the Front Panel MCU with no intervening circuitry save for connectors and printed wiring. At first I thought the relay clicking might be from the internal KAT3 ATU, but this behavior occurs in RX mode with no effort to transmit or activate ATU TUNE. It occurs with the ATU bypassed as well as in-circuit. I'm now wondering if the MCU developed a low temperature sensitivity during its long hiatus from daily use? Has anyone seen this kind of low temperature relay clicking when tuning the receiver right after a cold start?

[Elecraft] Elecraft 80M SSB Net Announcement
Please join us on 3806kHz (NOTE NOTE NOTE THE NEW FREQUENCY WHICH MOVES US INTO THE GENERAL CLASS BAND), 9PM ET Sunday (0200Z Monday). Note that the net stays on the same local time, when we switch back and forth to/from Daylight time, so the UTC time changes, but not the local time. Now that we have moved into Standard time and have shorter daylight hours, 80M should be stronger now during the winter. Your net control this week will be Dave, N8SBE. Hope to see you this evening on the net. 73, -- Dave, N8SBE __ 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 Message delivered to arch...@mail-archive.com
