I'm not surprised. The receiver is chock full of internally generated birdies. On a dead band, a bandscope looks like a major contest!73,Ed W0YK -------- Original message --------From: Bill Tippett <[email protected]> Date: 4/3/22 03:12 (GMT-08:00) To: Elecraft Reflector <[email protected]> Cc: [email protected] Subject: KWM-380 (was [Elecraft] K4 and Delivery Delays) W0YK wrote:The KWM-380 may have been a "hot radio" in some people's minds, but I can personally attest to the opposite. I have one, along with a number of KWM-2As and S-Lines. The 380 is a horrible performer. The receiver is incredibly noisy, obstructing reception of all but the loudest signals. The audio is distorted and filtering is poor. Collins' last hurrah was a dud.Hi Ed, I don't recall ever telling you this but your 380 also had horrible TX phase noise. In the early 80s, we were located within 5 miles of each other in CO, both running amps. Whenever you transmitted on 80 or 160, the phase noise would cover the entire CW bands. I don't recall what you replaced the 380 with but I was a very happy camper when you did!I take pride that my KSYN3A-updated K3 is still one of the cleanest CW signals on the bands.73, Bill W4ZV (ex-W0ZV) ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected]
