Hello Alan and all other LF-friends,

On Sunday an unusual noise aleted me to a PSK31 signal on 137.6, I swapped
programs to see Geri just finish working DL7YA on X-mode, and then

continue

with Wolf DF0WD also cross-mode.

Hi Geri,

I could copy your 2-way PSK QSO with DF0WD without any trouble, but this
should be not surprising since you have solid 579 signal here. DF0WD was
also 579 and 100% copy.
I have screenshots of your QSO (spectogram), the bandwidth of your PSK
signal was about 50Hz (+/- 25Hz from centerfrequency) with some weaker
'sideband' on the range of +/-35 to 45Hz from then centerfrequency. DF0WD
had a slighter broader bandwidth of 60Hz (+/-30Hz) but no additional
sidebands.
I will mail the pictures direct.
