Does anyone think the K2 actually needs an RF speech processor? The K2's built-in compressor seems to be extremely effective and seems to allow the K2 to put out a much punchier signal than you'd expect from a 10W radio. I can't see that you'd gain anything by using an outboard compressor. 73, -- Julian, G4ILO. (RSGB, ARRL, G-QRP, K2 #392) G4ILO's Shack: http://www.qsl.net/g4ilo
