[TenTec] INRAD 763

Howdy and HNY to the Group

I have a chance to buy an Omni VI Option 3 which is full of INRAD filters.  It also includes the INRAD 600 Hz ROOFING FILTER model 763.  This is an outboard filter that is ahead of the 9 MHz filters (N1 & N2).  I was wondering what thoughts you guys had about this roofing filter.  It sounds good “on paper” but a while ago I talked to Paul Clinton at Ten Tec and mentioned this filter to him.  He acted like Dracula confronted with direct sunlight.  He said that TenTec would not work on radios with this filter installed because the center frequency of the filter was not right and threw the whole alignment of the radio off.    What say you guys?

Also, on a side note, I ended up with the same roofing filter kit but is model 764 2.4 KHz for SSB.  I didn’t install it because it is for SSB and I’m primarily interested in CW.  So if anyone is interested you can send me an email off list.
