[TenTec] INRAD ROOFING FILTER & AUDIO MOD FOR OMNI VI

[cstoverva@aol.com]

Bill,

I have both, the roofing filter and the audio mods in my Omni IV+ and am very 
pleased with them.

I have the 600hz roofing filter for CW work which is switchable.  I have no 
way to measure the differences, but to my ear it makes a vast improvement.

I didn't like the audio quality on SSB, and though not much of an SSB 
operator anyway, I went ahead with the audio mod. It's cheap, but only fixes part of 
the problem.  I ended up adding the INRAD 755 SSB filter as well.  That 
eliminates the ripple in the bandpass, fixing the rest of the problem.

Bottom line:  Money well spent.

Good luck.
