Hi again. I searched the site but couldn't find an answer to my new problem. The radio has been working just fine for awhile now. However after trying a few qso's with strong stations, I realized that I have no transmit audio. I suspected a bad wire from the electret mic to the board, but that doesn't seem to be it. I don't know how to test the mic element, as I only have a DMM and no scope. So far I have measured PA current and have the 100ma, however when I do the hallloooww thing, I get no increase in current. I also monitored my signal on my base hf rig and get no S meter fluxuation as I yell into the mic. I'm in the process of printing out the mic input circuit so I can start taking voltage and resistance readings. Any suggestions are always appreciated. WA1MAD
