[TenTec] Audio mods for Ten Tec radios

[ditzian@alltel.net]

I have hated the SSB audio on my Ten-Tec Omni VI (whew, got the 
magic words in, I am OK for this reflector) since the day I got it.  It 
only sounds good in a headset; no speakers work well; I tried 
many.  However, I am also active in the digital modes, so I keep 
the audio going through my sound card.  

It took me two years to put two and two together, but when I finally 
turned up the computer speaker audio while in SSB operation, lo 
and behold, excellent audio.

As far as I can tell, if you have a digital mode processing program 
such as Zakanaka or MMTTY, that has a notch and/or filter, you 
may invoke those functions and they operate on the speaker audio. 
I am not certain about this situation, but sounds seem to change 
when I put in a dsp filter that is part of MMTTY.  BTW, this filter 
does not really improve copy.

Some setups may not output the input audio to speakers; audio 
may be muted if you use vox in the digital modes.

You do not need a digital modes program for this approach to work. 
All you need to do is to wire the radio's audio output to the mic or 
line input of your sound card and set the mixer controls correctly.

I have been looking for a program that would do audio functions 
using DSP, but have not found one that is understandable.  I 
suppose that this might be found in a fancy audio mixer program.

Of course, if you have fancy speakers, the audio controls will 
operate.

Perhaps there are others who would be interested in chasing down 
what is available, or who may have the programming skills to write 
what is needed.

The aforementioned mods cost $ 0.00 (plus tax, less trade-in) to 
implement, making them fully congruent with my parameters for 
ham radio improvements.
