[TenTec] Re: Al Gavenas' position on Front-End atenuation

[Charles Greene]

Hi,

I couldn't resist the fray.  I run with the AF gain control up about 3/4 
way.  Listen for the hum (it's always there), and back off until it isn't 
there any more.  Then control gain with the RF gain control.  That's on a 
bunch of rigs, notably the Omni-VI, 540 and K2.
