That's excellent advice from Gary! With #1361 I was failing the TX Gain Calibration on 60m only. I found one toroid had exactly the problem he describes (looking from the component side of the board). I took an X-Acto knife, scraped the toroid leads to expose bare wire and resoldered from the component side, which fixed the problem. 73, Bill W4ZV ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
