antioxidant paste. All new wiring in the new hamshack is copper (12-2
for 120vac and 10-3 for 240vac).

Thanks, Wes!
As a 99.9% CW operator,
I never looked into the Tech Mode options
for SSB testing in my K3. That's a really useful
feature! It's good to be reminded of the
built-in troubleshooting utilities in the K3.

Mike, K8CN
The K3 has a built-in two-tone generator. I've done 100s of two-tone IMD tests
on my K3 and K3S using them and an SDR-IQ as a spectrum analyzer.

K4 beta release R32.B1 is now available.
This release corrects a problem with TX DVR message play, where interrupting
playback could sometimes disable microphone audio. (Just in time for the next
big SSB contest) I'd like to thank our intrepid Field Test group as well as

Do you observe (or hear) sidebands outside

Can you perform a 2-tone test with an

ANT availability for selection can be configured by band. Connect the KT500

For years, I had only two antennas to switch at the tuner, but I have now
strung a third one.

Thanks, gang!

I may have had the same issue as you. Elecraft instructed me to listen
to my SSB signal via the monitor, start at 10watts and as you speak
start increasing the power. When you reach 12-15 watts I bet you will
hear your audio become distorted, sounds sort of like RF on your audio.
If not th
Elecrafters,
i have 2 K3's, #8862 and #2878.
Listeners using Panorama adapter gear like P3 or sdr radios report
unwanted strong sidebands when #8862 i bought from a friend is in use.
All is fine when #2878 is in use with same settings, power, external
amp, antenna and same mic.
