I thought my K2 receiver was dead, so I hooked up a signal generator to the antenna jack. I setup the signal generator for about 7.1mhz sine wave and 140mv p-p into a 50 ohm terminator. When I connect the signal generator to the connector, the signal goes away, just like it was grounded. I pulled terminal 3 of T4 in the transmitter section and the signal comes back. This transformer only has a couple of turns, so it seems reasonable that it would attenuate the signal. After scratching my head for a while, I reconnected the transformer winding and connected to an antenna. It seems as if the receiver works just fine. I guess you can't argue with success, but I don't understand what is going on here. Why would the signal from the signal generator get grounded at the antenna jack?
