Jack,
I'd say the radio will have to go back to the factory. Sounds like it's
stuck in transmit. Pulling the keying loop lines simply ungrounds the TX ENA
line. I guess that's forcing the radio back into receive (some rigs stay in
transmit but emit no RF when you disable TX ENA.)
As for the rotor, you didn't say what antenna you are trying to turn --
i.e., windload, etc. That makes a big difference in rotor selection. The
larger Yaesu GDX2800 is a good choice for many large yagis, but not for the
really big ones. Huge yagis usually require a prop pitch motor.
BTW, your rotor may be OK. The lightning strike may have fried the
controller. You might want to check the M2 manual to see if there are some
resistance and voltage checks you can do to determine that. The easiest way
would be to borrow a spare controller or rig up a circuit to apply the
correct turning voltages to the motor, brake (if any), etc.
