1. [TenTec] OMNI VI 9MHZ filters (score: 1): Author: "Paul DeWitte K9OT" <k9ot@mhtc.net>; Date: Wed, 24 Oct 2007 00:09:37 -0500; I put in a 219 250 hz filter in the 9 mhz if slot. It replaced a 400 hz Inrad filter. I find that it has quite a bit of attenuation (maybe 10db?). But it does reduce the QRN a lot.

Re: [TenTec] OMNI VI 9MHZ filters (score: 1): Author: Clark Savage Turner <csturner@kcbx.net>; Date: Wed, 24 Oct 2007 05:26:11 -0700; Hi Paul! 10 db would be too much for a normal filter, in my opinion. The OMNI VI has a little jumper to change the gain for that filter, it helps. Check on that. The other thing to check is that you; /archives//html/TenTec/2007-10/msg00449.html (8,143 bytes)

(Dub) Thornton" <dub@oklahoma.net>; Date: Wed, 24 Oct 2007 08:25:44 -0500; Paul: As Clarke advised, pay very close attention to the adjustment of the PBT. A tiny bit off in this adjustment can make a big dif in the apparent attenuation of the 250hz filter. "73" Dub -- J. W.; /archives//html/TenTec/2007-10/msg00450.html (8,087 bytes)

Re: [TenTec] OMNI VI 9MHZ filters (score: 1): Author: "Bob McGraw - K4TAX" <RMcGraw@Blomand.net>; Date: Wed, 24 Oct 2007 20:49:22 -0500; As I recall the PBT is for the 6.3 MHz IF and not the 9 MHz IF. Be sure the gain jumper is in the HI position. It's easy to miss the pin alignment. I only used a 500 Hz filter in the N-2 position wit; /archives//html/TenTec/2007-10/msg00455.html (9,984 bytes)

If the signals coming through the narrow 9 MHz IF filter are not also passing through the narrow 6.3 MHz IF you won't hear them. So the PBT has to be adjusted; /archives//html/TenTec/2007-10/msg00459.html (8,055 bytes)
