Tom, Check the voltages on Q8. When the K2 is powered, you should have 12 volts on the gate and the drain should go to a low voltage. That in turn should make Q1 conduct. 73, Don W3FPR On 8/6/2015 11:41 PM, Tom Field wrote: Having gotten the side tone situation sorted out, I now find I

Having gotten the side tone situation sorted out, I now find I have no power going to the KAT 100. I've checked the plug and voltage on D4, R12, and R11. There appears to be nothing getting through Q1, I have no voltage on the collector and no voltage on U8. Bad Q1? Tom KN6DR
