Bob, I watch my Orion's transmitted audio carefully on a scope and I run
the mike gain wide open using the TT studio mike or a Heil dual
cartridge (4/5) mike, and I never come close to flat topping. I have
not actually observed the dead span between 15-100, but now that you
bring it up, I'll take a look.
73, Joe

I have finally, after a year, hooked up my scope to the rf chain from my Ten Tec Orion. It appears the mic gain setting has no affect after turning it past "15". I have been running my Heil HC4 element with mic gain at 65 with no known ill effects, and noticed the same on the scope with it as with a two tone test signal inserted in the mic jack. No change in rf output with mic gain set anywhere between 15 and 100. I can vary rf power out with the power control just like on cw.
Is the Orions internal ALC for mic gain that good? Or am I missing something? If what I see on the scope is correct it is likely almost impossible to overdrive the Orion on voice. I appreciate the wisdom of ssb ops who know more than I about mics and mic inputs etc. thanks. 73 bob de w9ge
