Topband: Receivers

 I need to get the new Roofing filter mod done (won't be
here until mid December) on the MKV, and without the IF mod,
the MKV collapses.  I'll reserve final judgement until I get
all the mods done on the MKV.  So far, the MKV is a big yawn
by comparison.  The QSK on the 746 runs circles around the
MKV.>>>

What IF mod Ford? If it is adding IF gain ahead of the 2nd
mixer, I don't think that will help you a bit on low bands.
As a matter of fact, it is not much different than just
throwing a preamp ahead of the entire receiver.

I don't think you'll see a big difference with a new roofing
filter. Just be sure you go into the menu and turn the NB
gain to ZERO, or do the MKV mod on my web site that moves a
220 ohm resistor.
