[TenTec] Tentec roofing filters and Inrad filters for the Orion.

[Jason Buchanan]

Get both and test A/B comparison.  I've gone through a few 250Hz CW 
filters and they all have different characteristics - all the ones I 
had, anyway.  My INRAD 250Hz #751 CW filter performs as well as my stock 
TT 1.8KHz filter, but the TT 1.8 should have far lower loss than the 
INRAD.  If I had a microphone I'd probably pursue improving sideband 
receive but CW's all I do so there you have it ;-)


I remember going through 20+ saxophone mouthpieces when I was looking 
for a new one.  Took all day.  Same brand, same type, same size, same 
everything but each one was completely different.  I would up buying 
three and now use only one of them. 

Same thing goes for filters.  The Jupiter is outstanding in this regard 
because you don't have to screw with any of this filter picking 
business.  I just wish the Jupiter would narrow down to 100Hz instead of 
300Hz.
