[TenTec] O3 wish list

I agree.  I'd go with an external panadapter.  Why are people rumbling about 
an Orion III?  Let's get the O-II finalized first.  I am still waiting for 
an upgrade that will improve the NR part of the rig.  One that, when you 
activate it, will truly reduce the noise WITHOUT altering the audio quality 
of the voice you're receiving.

On some signals it seems to work okay but mostly it distorts the audio and 
acts erratically and I am running ver. 2.044A.  Different settings of the 
AGC threshold and manual AGC level do not seem to make much difference.
