[hpsdr] Latest Software

[Kjell Karlsen]

Hi Hans and all.

The problem is solved!

I used the software older than the one you use, Hans. When I updated, I  
have v2.2.3 (W5WC- 12/15/11) and now everything with attenuators works as  
expected. It seems as I have updated to a version that also have the new  
AGC (and may be the new TX Clipper?). I have to test it better.

73, Kjell
