Mr Trager is so unimpressed he is going to package it up and send it back as is .. a single band SSB receiver.? He is fed up with wasting time and money (full set of? 12 crystals was used to select better ones than those supplied) . The schema does not match what he has. He is "over it " and So am I? though there is a solution - use a semi cond bal modulator for Tx? and direct inject into the Tx transistor and add a Mute mosfet. .... too late. TEF
