Noise floor was slightly lower when the wind had abated somewhat...but not
ever as low as we've seen it on previous (windy) trips.
I'm not sure about the charging/discharging...doesn't that take the form of
a rapid built up of clicking noise? Sort of aPP! None of that
present...perha

After being notified by Powell Way, this was heard on an Eton E1 and 150 foot
wire:
1130 WLBA Gainesville, GA 5/10 2210 on the air with fair signal 120 miles east
of Memphis. Not a bad night time signal for a station authorized for 0.00 kW at
night. They are playing regional Mexican music. Go g
Yep; tried that too---also tried separate passive transformers and various
grounding schemes.
Yes, the noise level was substantially higher than previous expeditions with
the same lash-up. Good thing the Bev was also able to deliver as expected.
Oh BTW: C/N on the elevated antenna (for soli
Oh yah, you betcha! EVERYTHING was on battery. Computers isolated from
SDRs. Isolated grounds and the whole mugillah.
DX Engineering RF-CC1s were tried to no avail.

You mentioned that there were winds and dust during the time you were out
there. Makes me think that there was triboelectric charging and discharging
happening over your beverage. Question: If no winds and no dust is this noise
still there?

I'll chime in here and state that when ever there's any chance that the cable
or xfmr is causing a problem, I just hook up the Bev directly to the rx to see
if there's a major dfference in noise.
The noise level reported does seem quite high to me for a desert QTH but one
never knows. 73 KAZ

If you were in a remote area Mark, was there (ahem) something in your
own power supplies that might have been generating noise? If so,
maybe you should have been using coaxial chokes on your lead-ins, if
you were using coax lead-ins from matching transformers. Did you
have isolated grounds
Oops I should not have said sunspot group #11476 for last weekend. It
produced tenflares during the present work week.

Hi Mark the noise was probably from several tenflares associated with
sunspot group #11476. Discrete frequency radio bursts, tenflares and type IV
radio sweeps can occur with some solar flares. Some solar flares produce
allot of noise on the bands and some don't.

Boy Alex, I was hoping someone on the list had the answer. It was the sort
of noise that pervades the entire band; definitely not sparkling
atmospherics, just a continuous noise. It varied from day to day; Sunday
for example it had dropped a few db.
Wish I knew more about the relationship of

Was wondering about the high noise level. Would you have an opinion on it's
origin?
