Hi,
Stefan.
Thank
you for the WSPR report from France. I also get regular spots from F4DTL, F5WK
and F6CNI, so I know that there are regular WSPR listeners in France, even
though they cannot transmit on the 630m band.
Are
any countries still transmitting in the old 501 - 504 kHz
band?

Hi all,
Without any announcements i've been
in France again last weekend, like each year, meeting some friends on a
fieldday.
This time no LF experiments were planned and no MF / 630m,
because the band isn't still allocated in France. The WX was bad, no wind but
mostly raining.
However there was mobile internet available and so i
run some RX tests on 630m WSPR. First i wanted to use a my active ferrite
antenna but then i remembered that i have done a modification on my MF
converter so that it doesn't work in combination with that antenna. My last
chance was to use a simple piece of wire, connected to the RX. It turned out
that it was very easy there in the open field to get some very good results! I
just took a simple wire, 10 m long, dropped in some nearby (wet) hedge. The RX
was then grounded by a 10cm long/deep tent peg. No matching transformer or
resonance circuit was used!
Outside the city and far enough away from
DCF39, AFN and DLF it was quite easy to get a nice S/N from the transmitting
stations. The background noise was 20 dB above the RX+soundcard noise.
I've
been active for just a few hours and these are the best S/N reports for the
active stations (thanks to them for the interesting tests).
