[TenTec] OMNI 6

Sun Mar 7 16:40:41 EST 2021

True, about the Paragon.  It takes a lot of time and expertise to keep 
them running and to pay someone to fix them would be cost-prohibitive.  
I've been inside mine 2 or 3 times fixing problems with both PLL 
boards.  It's helpful to know where to probe to determine whether it's 
the major or the minor loop causing the unlock condition.  I had a 
friend whose Paragon I couldn't keep running for more than a few weeks 
at a time:  First I fixed the PLL;  then  the power supply blew up;  
then it wouldn't power up at all.  The last problem turned out to be a 
cracked solder joint on the power control board, plus the relay coil 
suppression diode, located /under/ the relay cover was shorted.

It /is/ a nice, radio, however, if you are good at troubleshooting... 
and patient.  With everything going SDR,  the Paragons and Omnis  are in 
the collector-boatanchor class. Will Ten-Tec stage a successful comeback?
