Thanks for the suggestions.? As for RF leakage, I'm in a situation where my dummy load is in a different state so can't do that.? I also have an issue with grounding since I'm in a condo with limited access to 'ground.'? But my other HF rigs seem to be OK with the same feed line.?
If you have limited access to ground ,you might be successful with an 'Artificial Ground'
It is a (variable)L ,(variable) C series resonant circuit with a sensitive mA or MicroA meter coupled to a toroid with the toroid sensing the current through the circuit . Connect one end of the circuit with the transceiver ground connection and the other circuit end? to a longest possible wire on the ground (possibly under the carpet )
At the operating frequency adjust L and C for maximum current as shown on the meter.
It is advisable to make the sensitivity of the meter adjustable with a (front-operated)potmeter
MFJ sell such a device . I have made one myself with the variable L being a roller inductor.
The MFJ variable L is stepwise -switchable
Ensure that the ground wire free end is properly insulated because there could be a HIGH RF VOLTAGE.
