There were two different setups that I know of. Mine has MRF-454s. Some have, as W6JC reported, MRF-458s. Phil C. Sr. k4dpk _______________________________________________ TenTec mailing list TenTec@

OK...My point was simply that I can't imagine a supplier planning a stoppage without first notifying it's major customer(s). In industry, that usually would only happen in a sudden, unplanned situati
I would suspect a poor connection or connector somewhere in the path from the reflected side of the wattmeter current transformer, or possibly around the reflected diode itself. Phil Chambley, Sr. k4
Mike... IF you go into it and poke around, start with Pin 4 of J1 on the LPF board, work back through L33 and R5 to the BAT41 diode. That will cover the reflected power detecting part of the SWR brid

The problem with the NTE replacement is that two of the tabs are turned 90 degrees and won't fit the PC board slots. Some of the other mfrs are same way. Phil Chambley, Sr. k4dpk ____________________

Ernie.... You say you had the carrier completely eliminated, and it re-appeared. How are you measuring? Do you use a scope, a wattmeter or a report from another ham? I've found it easier to listen on
I am in need of a transmit audio board (#81597) for the original Omni VI. Anyone have one laying around? If I have to do some troubleshooting, it's OK. Please let me know off list. Thanks and 73 Phil
