[Elecraft] KAT 100
Hi, I have a K2/100 and am looking for a KAT 100 in working order.

Re: [Elecraft] [K3] Odd transmit power output behavior on TX DATA
I figured out why it takes so much gain. Somewhere along the line, I switched sounds cards and I was outputting to the wrong channel. Amazing that I was able to get any transmit at all. > On Jan 3, 2023, at 9:55 PM, Bill Coleman via Elecraft > wrote: > > Well, I’ve half-way figured it out. > > I increased the LINE gain to the point where I can get 4-5 ALC bars, and now > I get plenty of power right away. > > Still trying to figure out why it takes so much gain, but I’ll puzzle that > out given time. > > Thanks everyone. > >> On Dec 30, 2022, at 1:24 PM, David Hachadorian wrote: >> >> It could be a momentary high SWR when starting a transmission because of >> some slow switching somewhere in line.

Re: [Elecraft] K3 - failing the milliwatt calibration
I just tried it with a brand-spanking new 50ohm BNC terminator. This eliminated the cable and adapters I needed for my 50 watt dummy load.

[Elecraft] K3 - failing the milliwatt calibration
I have two K3s, and both are failing the milliwatt calibration. One fails on 160m, the other on 6m, both with similar error messages. This is an example of the failure: Calibrating at 1.900 MHz IsSamplingComplete: Unexpected response ‘DB 2.08 MW;’ to ‘DB;’. Calibration power settled at ‘2.08 MW;’ 1 milliwatt calibration failed. Any ideas? __ 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
[Elecraft] What signals should appear on KIO3 LINE OUT?
What signals should appear on KIO3 LINE OUT? My microphone audio ALWAYS appears on the KIO LINE OUT. I have verified MON=0. Using Heil Proset into AD-1-K adapter into front panel MIC jack on K3. Stereo cable from KIO3 LIN OUT to LINE IN on a powered speaker. Nothing connected to KIO3 LIN IN. Nothing connected to KIO3 SPEAKER OUT. MON = 0 MIC SEL = FP.H MIC + LIN = ON KIO3 = nor LIN OUT = nor 10 --Scott, W5WZ From CQ-CONTEST VOL 239, Issue 20 Just to follow up on this one, I did an Anydesk session with Scott last night 11/21/2022, and after some experimentation, we discovered the problem. Scott had done everything right. It turns out he has three Elecraft K3 radios -- not K3s. They have line-level audio in and out. For some unknown reason, his mic audio was coming back on the line out when transmitting, even with the Monitor turned all the way off. If we took the audio out from the speaker vs line out, the problem went away and Mumble works perfectly. So -- either there is some weird K3 setting that causes this (and I've been using them 20+ years and don't know about it), or there is something astray in the I/O board of the K3. Anyway, we have a root cause. 73 Gerry W1VE __ 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
