Hi Sam,

There are quite a few folks who have installed the Inrad roofing 
filter in an Omni 6 Plus. K1FK came out with some changes for the 
installation of that filter that I think sure makes it's operation 
better. I have two Omni 6 Plus rigs and the 600 hz roofing filter 
installed in both of them. In the south part of Georgia, where I 
live, the summer QRN is typically at least 20dB over almost all of 
the time. One thing you quickly notice is that this 20dB over QRN is 
reduced to about S-7 to S-9 when the roofing filter is switched in. 
The QRN level is reduced but the signal you are listening to, is not. 
I personally think it is a great improvement to an already very good receiver.

All of the patinate technical data on these four-pole roofing filters 
is on the Inrad web site.
