Did you try more drive? If so, did
the amp flattop?

Subject: [TenTec] Problem with Orion 2 driving an Ameritron 811H Linear
I have found that my Orion 2 (w/ model 709 TT mike) will drive my linear to
a max. output of 300 watts while providing 40 watts of drive. My IC765 (w/
the model SM20 mike) will drive the same linear with 35 watts to an output
of 500 watts. I have switched coax leads, etc. to try to account for bad
hardware, etc.
As per suggestions from TenTec, I tune the rigs and adjust the linear
settings using only the CW mode, tried some compression, adjusted the mike
gain and even increased the
TX EQ (from zero to -12 ) and nothing increased the ability of the Orion 2
to provide more than a max. output of 300 watts. Meanwhile, the "good old"
IC765 cooks along yielding 500 watts for a drive of 30 watts. What 'am I
overlooking? The only variable I can see is the rigs/mikes. Has anyone run
into a similar problem or do you have any suggestions as to what I should
try next?
Will appreciate any input you could provide.
73, Tom N3XQ
