I am thinking about getting an Omni VI Plus from my brother. I would add the
Inrad roofing filter and 9mhz narrow filters. From what I can tell, the VI
Plus is set up for a 750 hz offset, as far as the stock filters go. Yikes, I
like less than 500.
If I understand this properly, although the VI Plus has variable offset/pitch,
the 9mhz N1/N2 filter and any roofing filter have to be set for a lower offset
if all is going to work. From what I can see, my choice on the roofing filter
if I want this is the Inrad 765.
With discontinuing the 28# numbers, is there a 250hz 9mhz filter, with the
passband centered around 500hz? Or the 6.3mhz if filter?
Finally, I have heard a rumor that running the lower offset requires a
re-alignment of the rig. This makes no sense to me...but what do I know?
Input is appreciated.
Thanks,
Art, KC2G
