These are hifi and I get serious thumps from the K2, even with the AF 1 turned on. This is true with other rigs as well. The SCAF 1 removes this noise. I just need to make sure I don't overdrive the SCAF 1 as it is very sensitive to this. The filter really cleans up less than pure sidetone audio, too. I would like to get some good communication 'phones, without the microphone thingee. Any recommendations. I like the kind that seal out external noise. I like to use a bug but the damper clacking is distracting to me. 73 Rick Dettinger K7MW
