Hi,
Rog, LF.
You've
got to be within 100Hz of each other so that you both fit on my "Argo"
screen. It doesn't matter too much if you drift into each other, as it's
quite possible to differentiate between the two sets of signals. The G0MRF
beacon on 503.7 is pretty strong at this location, so my preference would be
around 503.8 and above, or more-or-less where you are now on
501.5.
I
won't be able to do any more overnight monitoring until Monday night, as I am
going to QSY with my trusty W&G to IO70WJ (Devon) for the week-end, and will
do some listening from there. Perhaps we can fix up something for next
week.
BTW,
I'm going to burn a CD of the overnight stuff for Alan. If you want a copy, let
me know.

Dave/wcb,
Tks for all info, esp the 6dB comp.
What freq separation would suit?
Rog.

Subject: LF: [ 500]Two GW's Testing... GW4HXO overnight
run
Mike, LF.
Good signals from GW4HXO throughout the night,
with a marked drop in
strength between 0350 and 0420 utc, and reversion to
daytime signal levels
therafter. The propagation showed the same sort of
pattern as GW3UEPs
signals, but Mike seems to be consistently stronger by
around 6 dB
Mike's signals reached a sort of peak at 2330utc, and
stayed at good audible
strength until 0350 utc, with moderate QSB having a
two or three minute
cycle. His signals didn't exatctly "fall off a cliff"
after 0350utc, but a
fairly rapid decrease in signal strength occurred,
perhaps as much as 10 dB,
but I'm guessing.
Mike's signals have been
visible all morning [couldn't listen - I was at
work :-((], then stopped
abruptly at about 1410 utc this afternoon.
It would be really
interesting to run an overnight comparison between GW4HXO
and GW3UEP, but
at the moment, they're beaconing at opposite ends of the
band!
I'm
also seeing what I assume to be Finbar clearly on 503.792 at the
moment.
Can't make out his call-sign by ear.
Night and day
comparison screenshots of GW4HXO attached.

RE: LF: [ 500]; Two GW's Testing... GW4HXO
Dave, LF,
GW4HXO
is quite a bit stronger now, and clearly audible in a 1.74 Khz
bandwidth
(Wierd SPM-30 feature) I'd give him 439 by ear. My background
noise level
is sitting at -74 dBm, and Mike is a dB or two above that.
(About 50
micro-volts at the RX terminals)
I'm using a 20m long "Tee" at 6m,
tuned with a big coil which is
link-coupled to the RX. It does pick up a
lot of SMPSU crud from nearby
wiring. A loop would be much
quieter.
I'll leave ARGO running overnight to see what happens to the
signal levels
around dawn.

Still amazed at
the difference in reception between Bracknell and
Iver (the whole of about
10 miles...). Currently hearing (and not
much different from midday here)
with my two ears.....
505.15 DI2BE
569
503.8 GW4HXO 559, very consistent
all day
503.75 G0MRF
599
503.65 G4WGT
579
503.2 GI4PDE traces, was
solid earlier
502.2 G3XIZ in QSO with
G3UNT both 599
501.5 GW3UEP
329
(All frequencies approximate, difficult to read to 10Hz accuracy
when
tuning CW by ear...).
I can even hear 'HXO and 'WGT under
'MRF's psk in my 400Hz filter
A couple of CQs from here earlier went
unanswered...
