[CQ-Contest] Re: TS-950SD Rcvr Problems

Chris:

Does the rig go into transmit when this happens?

I had something similar happen with my FT-1000, but it went into xmit
when there was a very stron local CW signal.  I found that the culprit
was apparently the adjustment of VOX and Anti-VOX.  The rig would go
into transmit (with no power output, I might add) when the AGC got above
a certain level.  I resolved it by changing the VOX/Anti-Vox settings.

Check to see if your problem manifests itself during reception of strong
signals.

I'm having trouble with my TS-950SD.  Every so often, the receiver goes
dead.  The S-meter goes full scale and I can't hear anything.  It's as
if
the RF-gain was turned all the way back.

Most of the time it will correct itself within a second or two.
Sometimes
cycling the power on an off will correct it, other times I have to leave

the power off for a while.  It's hit and miss.  Sometimes it happens
shortly after I turn on the rig, other times it starts happening after
the
rig has been on for a few hours.  Sometimes the receiver will go quiet
(and
full S-meter) for a long time (minutes), other times it will quickly
cycle
between working and not working, as if someone was playing with the
RF-gain
knob.  I've reset the microprocessor, but it's still the same.

Has anyone experienced this before (not necessarily with a TS-950)?
What
was the root cause?
