I'm in receive mode tonight running OP2H and uploading Argo grabs of
Bob's big signal at 10 min intervals:

I found an antique RF ampmeter which tells me the antenna current was .4
amp with 150 watts leaving the shack. Then with an IR thermometer I
discovered the stack of three FT-240-77 toroids that work well for
antenna matching on 73, 137 and 500 kc was heating up about 25 deg above
ambient temp. I've located some J type toroids. Would I be wasting my
time trying those for impedance matching?
