[1000mp] Adjusting the MP's RF output/speech processor settings

Mon, 28 Oct 2002 15:35:26 -0500

Didn't the early FT1000MPs have a problem which caused a huge 
power spike on the initial output when using the speech processor?

Mine never did this, but I recall reading something about it. It would 
have been  pre-1997.
