Hello Harmut.
No not 2.5mW this evening.
The beacon was down for reprogramming today and I took the opportunity to
add a key input.
With a friend coming over to see the 500k station I turned up the drive to
the amplifier to make some CW QSOs on 502.0
I worked Mal G3KEV at 19.00 for my second QSO on 500k received
559 report
followed by Brian G3UNT
and then Alan G3XAQ by which time Garo G0PZA had taken over my
straight key.
Power was between 50 and 70mW at different times. I returned to
503.700 for just two cycles of the beacon. You appear to have captured the
entire sequence. What is particually remarkable about the capture is that
after the last QRSS MRF, where the signal is coming up in QSB,
you can see two sidebands offset by 15Hz and then an area of 'energy' over 20 Hz
or so. These signals are from the PSK phase reversals followed by the PSK
data. To see this PSK31 data signal at 760km when it is spread over a relatively
wide bandwidth demonstrates some good condtions and presumably low noise / good
RX at your end.
Thank you. - Seeing the PSK was really nice.

Just captured MRF on 503.7 kHz. Is this still 2.5 mW
ERP?
Capture can be seen

G0MRF putting a very solid 579 into Canterbury just now at 2030 on
502.0. QRN low again tonight. His pal G0PZA, Garo, is on he key.
