Regarding the message below... I too have adjusted my KX3s RXEQ to enhance the audio frequency spectrum that is for voice (and CW) communications. Using my KX3 (and other radios like my collection of Heath QRP radios) in my ham shack I use West Mountain Radios Comm Speakers. They are advertised as RF proof... and I think they are right. Operating 200 watts doesn't interfere with the WMR speakers or I have no RFI in my shack- how likely is that? Oh yah, they sound pretty well with my KX3, HW7, HW8, HW9. See: http://www.westmountainradio.com/product_info.php?products_id=com_spkr I got mine at HRO. FWIW, Rich KR7W

Remember that the KX3 is specifically designed to be a backpacking rig, so everything, including the audio amp, is designed to be stingy about using battery power. One simple thing we can do to maximize the audio output level is to use RXEQ to roll off the lower three bands. The sound in these lower bands makes no contribution to communications, but it does use power, so when we get rid of it, we can use the power for the sound that matters. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
