Thread-topic: RE: MF WSPR from France

Hi Dave,

 

in Belgium we can use both 472-479 kHz and 501-504 kHz.

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?

Subject: LF: MF WSPR from France

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).
