Jim (K9YC),

Very nice job on your report last month.

I did some work on a multi-transmitter Field Day site a coulple of years ago when I wanted to run 2 transmitters on the same band where W3NQN type filters could not be used to reduce phase noise. It can be found at:

http://www.w0qe.com/Technical_Topics/phase_noise_and_overload_testing.html

and shows how the K3 was the best radio I tested. By the way we operated 40m CW and 40m RTTY at the same time with NO filters. Ditto also for 20m CW and 20M RTTY with NO interference. The web page has a link to a PDF of the document if interested.

73,
Larry, W0QE
