Solution for Receive Audio Failure
Problem: Has anyone experienced a total lack
of receive signal with the 1000MP, as this happened to me on two occasions in
the recent ARRL SSB Contest. It only occurs when the EDSP filtering is in use,
and switching off the rig for a few seconds then back on > brings it back to
"life". This would appear to indicate some sort of "poor connection" or w.h.y.,
but where and what exactly? The receiver works fine with the EDSP "off", but the
failure happened on at least two occasions with the EDSP "on". Switching bands
had no affect, the only way to clear the fault > was to hit the on/off button.
Anyone know if this has been documented anywhere? Steve GW4BLE
Solution: I got many replies to check the
squelch and RF gain etc. but it took many, many months to figure this out and it
was a poor connection with the external speaker plug. Not in the rig but on the
speaker cord. I had one of those adapters that went from 1/8 mini phone plug to
RCA and then a RCA "Y " connector. It seems that only when EDSP was on the
problem would occur. It first happened about 2 years ago then 10 months no
problem. Happened at FD and I removed all peripherals and hooked them up again
and all was FB. It was when I was moving the rig to the new shack that I was
able to duplicate the problem.. Got rid of the adapter and "Y" and just use a
good patch cord from the rig to SP-8 and it is solid. Your switching the rig off
and on again could be just enough movement to make the connection work again. I
did the same. Kicking the bench works too. :-) 73 Norm, W3IZ
Question: Stupid question but any chance the squelch control has found it's way
close to threshold? I remember being embarrassed with that issue many years ago
with a TS-440. My first radio with a squelch control :-) Paul VE3SY
Solution: I have had several similar
experiences with my 1000MP. It occurs when I powered ON following a power OFF
while the RX DSP was switched in. Upon powering ON, there is either (a) no rx
audio out, or (b) a "motoboating" oscillatory audio output. Swtiching the DSP to
OFF results in proper audio output, although the problem returns when the DSP
button is again depressed. Simply powering OFF/ON with DSP OFF appears to
provide a reset that resolves the problem. This is a relatively rare event and
has not been of great concern to me, but it has occurred approximately a
half-dozen times or so over the last few years. 73,
