[TenTec] Paragon behavior

[Tim & Darlene Isom]

I am a sysop for a MARS PACTOR switch.  We are using Paragons for 
the switch operation and I am wondering if anyone has seen the 
following behavior and if so what is the problem and perhaps the cure.

On Saturday, 25 September, I had to check our PACTOR switch 
because no one was able to log into the switch to get traffic.  I 
initially found the Paragon working but the audio was just a loud 
buzz and when the tuning dial was turned the display remained on 
the same frequency even though I was moving the tuner.  I did a 
hard reset of the rig and things seemed to be cured.

Today, 26 September, I had to again check the switch due to the 
same problem.  I turned the rig off and on (without a reset) and 
things were fine, I then had another operator connect to the 
switch - as traffic was being downloaded by the remote operator 
the switch was functioning but then stopped - the TNC (a PK232MBX) 
had the send light lock on, however the rig was no longer 
transmitting, my loud noise was back and the display was blank.  I 
do not believe the problem is with the TNC - I believe the issue 
is related to the radio.

Any help would be appreciated.
