Thanks to all three of you who responded. Don, you put your finger on the problem. Soldering a wire across the differential inputs of U3 produced a clean sidetone. The voltage on the Q10 gate was only 2 volts during transmit. After pulling Q10, I am now getting 6 volts on that solder point, and have requested a replacement 2N7000 from Elecraft. Many thanks for your help! and I believe this is the last of a couple of build-problems! 73, David AC4BN ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected]
