[Elecraft] Help - K-3 TMP cables
Thanks, everyone who responded so quickly. I'm sure I'll be able to resolve the problem in the morning . Didn't see the KSYN3A instructions when I looked on the website -- 73, Pete N4ZR __ 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

Pete, Here is the link for the KSYN3A synthesizer installation instructions. See Figure 13 on page 17 for the cable routing for a dual receive K3. https://ftp.elecraft.com/K3S/Manuals%20Downloads/E740257%20KSYN3A%20Installation%20Rev%20A6.pdf 73, Bill - NA5DX On 3/11/2023 4:13 PM, Pete Smith N4ZR wrote: I'm in a bit of a mess.
