Re: [TenTec] Omni VI filters

Hi Barry,

Ok.  It's probably a PIN diode problem like Ken said in another post.  
I'll check those.  Seems odd that the 2.4 Kc filter and the 500 Hz 
filter are both a couple S units lower output than the 1.8 Kc filter.  I 
have another 1.8 Kc filter and a 500 Hz filter. No change when I swap 
them out.  I'll see what I can find.
