There is an ELECRAFT Application Note Front Panel Microphone Circuit Modification.
You have it on your K3? 73s - Twan - PA0KV |I have a situation with the CMP and ACL graphs indicating and a scratchy |noise that happens many times when I press the PTT button pn my MH2 mic. |If I tap it or speak into it the graphs return to normal and the noise |disappears I grounded pin 2 on the mic jack on the K3 and there is no noise or |graph indication. I connected my Kenwood mic and it happens with it |also. Could there be some RF feedback getting into the mic circuit ? |K1DWZ ______________________________________________________________ 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
