[AMRadio] Testing a modulator

[RICHARD GEORGE]

How does one test a modulator. I will soon have a modulator capable of 
around 100 watts of audio. I know that I do not want to run the secondary of 
the transformer unloaded. Would it be OK to make dummy load out of a bunch 
of parallel connected 3 watt resistors, say about 60 watts worth at the dc 
resistance I will be looking at (3000 ohms).
I know that this would only be good for short tests using my O scope and 
audio gen. Any better ways.

I ran a lot of VHF AM back in the day, but only at 5 - 10 watt levels.
