More info re my "pseudonoise" --

1.  Tim...no relay click at > < 220 kHz...but a "click" is heard at > < 440 kHz as the "WIDE" indicator of the increased bandwidth filter kicks in...however, see #4 below for solution to the pseudonoise...probably a deep glich in the SDR software.

2.  George...no change with WNB setting...

3.  Paul...no changes with all house lights / motors / plasma TV on versus off...

4.  Fred...THE SOLUTION!!!  "Waterfall Display" was set for "ON", and when switched to "OFF" all the pseudonoise disappeared, with no discernable change in the waterfall appearance...

Thank you to all!  A very peculiar finding indeed!   Mike, K6DRY
