maybe i am misunderstanding but how is this any different from having long wire attached to the transmitter’s ground which is radiating rf like in a dipole setup?
I’m not sure your query was directed at my post but I will assume so and comment. The difference is that there is not connection to the antenna output per se, only to the ground output. I think what was happening was that the capacitive coupling from primary to secondary in the output transformer was feeding RF into my ground circuit (water pipe) and this ground “lead” was radiating. The return path was probably through the tx. circuit ground via the computer audio gnd to the power line ground. This is the same as connecting the antenna output of a transmitter to the ground and having the ground lead act as a radiator working against the power ground.
