[Elecraft] NR

[The Smiths]

I have a constant S5 to S7 noise floor here at my QTH.. It's both QRN and QRM.  This is especially true when the conditions change so that the DX is present. I find that when I use NR 3-5 with Med5 I reduce the QRN by at least 2 S units.  I've never had an NR that actually reduced random band noise, other than perhaps electrical impulse generators.  Granted, I've come from the Yaesu world.

Merv,



Interesting, I have used the shift and on my unit the FC* is at 150. I find
moving it down to 90 helps (toning down the higher pitches noise) as well as
playing with the bandwidth (trial and re-trial). Noise seems to be about S3
in my area with no improvement or reduction in noise using DSP (both IF's)
or using Noise Reduction at any of the settings. NR seems to be pretty
ineffective unless it's just operator error but, I think I have a fair
understanding of going through the settings while listening to the
atmospheric noise..



Thanks for your comments,



Ron N6SC
