Don't count your chickens before they hatch. Haste makes waste. Sometimes
"simple" solutions don't work.

Info on an earlier post today proclaims my solution. Not so :-( Changing
color display to 16 merely cut the noise on one frequency, and the noise
appears on a couple of different frequencies.

Therefore, before I post solutions - like a good scientist - I will carefully
observe and test and re-test.
