Hi MF, There is a fieldday of our local radio club. I will be there and transmit and receive a bit on MF. Most likely there is no chance to use a large antenna so i will use my small 1m diameter loop
Hi Joe, That choke was just intended to improve the supply voltage stability (low pass filtering). It's value is not critical. Meanwhile i've learned that it can be helpful to spend a ferrite bead in

Hello Iban, Thanks for watching :-) Your receive setup is one of the best on LF and MF! 73, Stefan Am 12.05.2015 19:06, schrieb Iban Cardona: Hi Stefan nice signals in Spain some days ago. 2200 -9 4.
Hi Luis, Good luck for your test! It is interesting! Maybe it is not the best time in the year :-) Very strong QRN today due to local thunderstorms. Anyway my grabbers are running 24/7. My frequency
Mike, Interesting to read about your RX equipment. Sounds like a bit effort but must be a great fun as well :-) I like the different antennas, and i'm glad to read that there is interest to get my si
Markus, It's 474.2 kHz dial ;-) 73 Am 31.05.2015 00:36, schrieb Markus Vester: Hi Mike, you won't need separate receivers and PCs just for observing WSPR at both speeds. Frequency bands are adjacent
Markus, What about the old slow-WSPR by DF6NM? It could be useful to try WSPR-4 for experiments. There is not just 2 and 15. And WSPR-120 on VLF... No problem! 73, Stefan Am 31.05.2015 01:28, schrieb
Mike, how are things looking now on your side? Strong QRN? Same QRM-QRG than last night? 73, Stefan Am 31.05.2015 01:15, schrieb Michael Sapp: RRR Stefan, if you could slide up a few Hz that would be
Hi Jacek, LF, For the first time i have problems to write emails to this list. BTW i wonder why this happens on a late friday afternoon! For the moment i'm using another account now. I'm in contact w
Hi Paul, ULF, Sorry for my late reply. The transmission takes quite long, so there is no need to stress with my answer :-) Thanks for the overview of the signal received in Bielefeld. Quite strong an
Hi Paul, ULF, Wow, just amazing! Can't we say we already made it? Isn't it extremely unlikely that this is something elso than my signal?? A first signal detection by amateurs on the 101 km band betw

Hm, i remember from my LF days that people tend to say i have "no ears" when i didn't copy them. They copied me very good and so their easy conclusion was that obviously i do not receive well. Actual

Hi Paul, Interesting. Do you also use the noise normalisation function which proved to be useful in recent stackings on 5170 Hz? Still a few weeks before the 6 channel input soundcard for the Raspi a
Hi Paul, While waiting for the lunch today in a restaurant i Berlin, i checked the antenna current in Heidelberg on the smart phone (you know :-) ). I suddenly discovered that the safety function has

Hi Paul, I've never had serious problems with the WSJT-X software running in WSPR-15 mode. However they did not continue to develop WSPR-15 since some years. For example the multi-pass decode option
