[1000mp] MP Relay/Receive Problem

Mon, 27 May 2002 07:59:16 -0400

I'm pretty sure I've observed it on 20-10M and Mike KC7V confirms it is not 
band-limited.  I kick myself for not recording the WPX contest audio 
(Writelog), because then I could let everyone (and Yaesu) hear WAV files of 
it happening.  Darn, darn, darn.

I suspect this problem has been happening to many MP owners out there and 
they aren't aware.  By bringing it to the attention of the reflector, I 
think we'll see a lot more reports of it in the future by serious contesters 
who spend a lot of time running (cq'ing) with the MP.

It sure would be great if Yaesu would solve this one, but I'm not holding my 
breath.  As SM0KCO suggests, it very well might be a semiconductor problem, 
not a relay problem.
