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.
