This can only happen if you have CONFIG:SPKRS set to 2. If you set it to 1, the right speaker channel is turned off, so a mono plug can be safely used. In addition to this, an upcoming beta firmware release detects the case where SPKRS is set to 2, a mono plug is inserted, and speaker volume is set to a moderate or high level. (The firmware looks for excess receive-mode current drain due to the AF amp IC going into thermal shutdown.) If this happens, the K3 will automatically set SPKRS to 1, reminding you with a brief flashed message. 73, Wayne N6KR --- http://www.elecraft.com ______________________________________________________________ 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
