I checked the transverter oscillator was working and power was being produced into a dummy load, but there is no current showing in the antenna current meter. Maybe the fault is with this?
So, I tested the transverter connecting it directly to the earth-electrode "antenna" in the ground (no matching transformer). Every TX period I received 4-7 spots per TX period. My ERP is at most 10mW, probably far less.
Furthermost was 209km.
