[TenTec] Omni 6 Audio Mod

[Wa4aos@aol.com]

Yes, the audio does go through the DSP stuff on the Omni 6+ and it would be a 
challenge to reroute it since you would lose some feature functionality. The 
raw audio before DSP sounds much better and you should give it a listen 
sometime.
The INRAD mod works great but there is one  thing to know. The IF/AF board on 
the Omni 6 comes in at least 2 flavors. One is discrete through-the-hole and 
the other is SMT. I believe INRAD still provides both sets of parts with 
their kit.
Naturally, most of the boards that I have modified were SMT and a bit more 
challenging than the older board. INRAD does give a good pic to assist  with 
the mod but if you are inexperienced with working with SMT devices, BE 
CAREFUL. !!!
It is all too easy to pull a trace and damage the board.

With the INRAD mod, you will notice less pinch in the upper end and a bit 
more lows; a nice change from stock. If you like to listen to SSB the INRAD 
filters are very nice as well. The 2.8 KHz filter really opens the audio and 
the O 6 becomes very nice to listen to. 
Then again, I just listened to the Orion and WOW ! ! ! What a wonderful 
sounding audio stage. The best audio that I have ever heard out of any HF 
Radio. Makes those really nice Collins receivers sound anemic by comparison. 
As much as I HATE SMT boxes, I am going to purchase an Orion just for the 
audio. Who cares if you can't find parts in 10 years??? Hi
