[1000mp] New Roofing Filter

[Brian Smithson]

I do not own an MP-series radio yet, but it will probably be an xmas
purchase. My question about the roofing filter relates to the 'VRF'. As I
understand it, the 'VRF' can be engaged to narrow the bandwidth ahead of all
the pre-amps and the first IF. Is this what the roofing filter does, and how
is it different?

I have a question for those who have recently installed the new Inrad
roofing filter.

1. Can you detect insertion loss? Was it necessary to adjust/compensate the
IF gain in Menu 9? Did it affect the sensitivity in any way? I have
presently the IF mod installed and feel it's a worthwhile improvement for
signal to noise improvement but do you lose this in favor of better dynamic
range?

I have read the pdf file and understand what this filter is doing but is
there a trade-off.

2. Is it worth $165.00?
