MIKE, BE CAREFUL
Yes, the current consumption varies from band to band and when
limiting to 20A, you may not always get 100w out.
However, the 962 is incorporated in the protection circuitry of
the Omni VI+ and has over-current shutdown (which I'm sure you
have already experienced). If you use a non-T-T P.S., you need
to insert an external automatic circuit breaker in the line.
These things typically come in values of 15A or 20A - dunno if
you can get one for 22A. Without this circuit breaker, you run a
HIGH RISK of blowing your final transistors. DON'T SAY WE DIDN'T
TELL YOU if you blow the things!
I recommend returning to using the Model 962 and forget about the
missing 10 watts on some bands. It will never be noticed in any
QSO.

Subject: [TenTec] Omni 6+ Input vs Output power?
Is it common for the DC input amps, or Ic, to vary from 15 to 22+
to obtain 100 watts output into 50 ohms when changing bands?
With my Omni 6, I was not able to get 100W output on 3 bands
before my former 962 supply would trip off at 20A. Have since
replaced it with a beefier more stable supply with an accurate dc
ammeter. The Ic scale runs approx. 1-2 A higher than the supply
dc.
Has anyone had a problem running CW at over 20A DC input with the
Omni 6? The bands where the efficiency goes to pot (Idc exceeds
20A for 100W rf out) are 160, 30, and 15. I know this agrees
with at least one other Omni 6 user. Any more?
Thanks &
73, Mike, AC5P
