[Yaesu] ft 2000 and Alpha 8410

[Dr. Gerald N. Johnson]

That's a standard problem running with transverters too. I don't know 
any details about the FT-2000, but if it sets the power with ALC many 
rigs spike. You can try cutting the power by backing off on the 
transmitter gain, like the microphone gain. Minimize the work ALC has to 
do. In my FT-857s I found an alignment menu setting for transmitter gain 
that I was able to back off (and a global reset had set to the maximum 
possible gain in one of them that spiked) and prevent spikes.

Some for transverters have applied a fixed bias to the exciter ALC to 
cut the power and prevent spikes.
