[TenTec] Problem with Orion 2 driving an Ameritron 811H Linear

[Mike Schatzberg]

Hello Tom: You might want to take a look at the article on my website as to how to optimize the processor in the O2 to drive your amplifier more easily on SSB. You will find the page here: http://home.earthlink.net/%7Echerokeehillfarm/id2.html 73 and Happy DXing, Mike W2AJI

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
