Stefan,

           Bob turns his power output down when on WSPR, he can generate an additional 6-10dB in CW, and has made CW contacts with Finbar in Ireland  and also did a mixed mode contact with Finbar, transmitting on ssb and receiving on CW.

Hello Roelof,

OK so far. You want to say that a a CW QSO would be possible with Bob? A CW QSO by using a 10 Hz BW CW filter? Sounds terrible i guess ;-)
For me there is no chance since i'm farer from the sea and i assume to have more QRM here (?). Furthermore my signal is to weak, on MF. I guess i would need another 6 dB here.

However, see attached... :-)

Hello Stefan,

Last night I found this decodes from WE2XGR/6.
There are quite a few hat show an SNR > -20.
I found that a SNR of -20 is about the threshold level for aural CW in a 10 Hz bandwidth for skilled ears!.
