[TenTec] OII V2.044A

[kc9cdt at aol.com]

Barry,
Well, yes you can...but once you get PBT at - levels the recovered 
audio is too muffled to hear well most of the time (on weak 
signals)...I find I have to run PBT up to + 140 -190 most of the time.

Some of this is my ears....I have some high freq. hearing loss (wo 
doesn't at 62) . You would think that would help!
In my scenrio the Halli SX-117 just was right...the audio was clear, 
popping right out of the noise...but the HF hiss is gone.

Also, very pleasant for rag chew.

By the way... I have been working tons of DX on 40 and 80 
tonight....OII is working super. Lous sigs 2 - 3 KC apart and OII just 
pickes them out.
Roofing filter on 2.4 and DSP on 2.1.
73,
Lee, KC9CDT

No high frequency cutoff on the Orion II?  Between Hi Cut, BW, and PBT
why aren't you able to cutoff high frequencies?
