[1000mp] Noise Blanker IMD

[Barrie Smith]

I use my Mark V, with the FTV-1000, for 6M EME using JT44.  Been fairly
successful so far.

I've used this system with the NB on and off, with no apparent difference,
even though my background noise level can vary by 2 to 3 db from day to day.

I have not changed the menu settings from default.

Anyone have any ideas if there could be a menu setting that would work well
for JT44 other than the default setting?

TIA, Barrie, W7ALW
