Is stacking of let's say qrss3 signals a possebility? This is used with
succes on 30 M and other HF bands,so the software is available...

MF !!!!!!!!!!!!!!!!!!!!!!! ;-)

Edgar in Tasmania was recently asking if i have some plans about DX=20
experiments on 630m. Well that is a path of > 16000 km. However we do=20
not have real experience if that is easier than 2200m or rather
impossible.

At least i know that there was not even a single decode by UA0SNV in my

MF WSPR and QRSS tests so far, while it is no problem on LF (OK my MF=20
signal is weaker than my LF signal). Thus i would guess that it is much

harder to get some traces of a signal on 630m. We will try anyway!

I'm starting to run a QRSS-60 transmission on 476.172 kHz (+- a few Hz)

for the night. Maybe someone across the pond will catch something. We,

or at least i still have no experience about the QSB problem on very=20
slow QRSS transmissions on MF. It would be interesting to see a
spectrogram.

On air in a few minutes.

PS: No, not only beacon transmissions, i've just had a > 1 hour long CW

QSO with PA0LCE and DK6SX/p! Also contacts to OK2BVG and S57A.
