I suspect the TX Gain Calibration would fail due to "High SWR".
Yes, TX CAL will do that. You need a good 50 ohm non-reactive dummy
load good to 54MHz.
Light bulbs worked well with old transmitters that had an output circuit
that could match most anything. We did not need tuners back then - but
then along came limited range transmitter output circuits which
sometimes needed a tuner, but today's transmitters need to see a 50 ohm
non-reactive load if they are to work properly - and then tuners became
essential - they just moved the matching network out of the transmitter
and put the equivalent into another box called an antenna tuner.
