[1000mp] FT-1000MP Typical Maximum Power?

Sat, 29 Dec 2001 06:53:35 -0000

It has been pointed out---by W8JI, among others---that most radios exhibit
better IM performance at rated output than at any other output. That said,
it is also true that most ham amplifiers are driven to full output by less
than 100W. There may be other ways to reduce output, but the RF output
control is certainly the most practical.
