Hello everyone
I have been going thru the omni c over the past several days getting it back in
shape. It’s running well and my last remaining challenge was the power output.
On most bands I was getting under 50w so figured I may have had a blown final.
Out came the mrf458’s (intact) and replaced with PT9784’s I had on hand...not a
lot of difference. I then swapped out the pt3647 devices also located in the
final PA with a pair of 2sc2166’s.
I realize the power output specs vary to some degree and have a bit of range,
and normallly higher freq will be a bit less.... but I am curious why 40m is
now my lowest output...with 13.8 v measured at the radio this is the result:
160. 65
80. 85
40. 75
30. 80
20. 95
15. 80
28. 65
Any thoughts why 40 is the lowest band?
