[Yaesu] FT450 loss of receive

Thu Jan 27 13:23:29 EST 2011

I agree the chances of it recurring after being sent to Yaesu are pretty small (unless all the bouncing around changes it from intemittant to permanent...). I'd probably shoot some contact cleaner into the volume pot and AGC control first and see if it disappears

Subject: [Yaesu] FT450 loss of receive
I have a fairly new Yaesu FT450 that has a very intermittant problem. Once
in a while, when it has been on for a while but unused (just sitting
receiving) the receive level will drop down. It is almost like the AGC gets
stuck after hearing a loud signal or so. It happened twice right after I
got the rig, about 1 week apart and then last night after not showing this
problem for over a month. When it occured last night I went to transmit at
full power and the rig turned off. When I turned the rig back on it was
receiving fine (I didn't know the receive was down until this happened, I
just thought the band was quiet). In the past turning the rig off and then
on has fixed it as well.
I bought this new in November so it has 10 months left on the warranty, but
I kind of hate blindly sending it the Yaesu as they will probably be unable
to reproduce the problem. I wonder if anyone else has had this problem and
know what causes it or where to look for a solution.
