Hello Roger, LF

Congratulations, I was surprised myself to see your callsign and ERP in the log.

I think you could do better still with your current setup. I have some undecoded
traces from you that are even stronger that the ones producing the spots from
me. If you look at the attached screenshot there is "wobble" on your signal.
The trace just below your lefthand one decoded at -18dB. Both traces from you
in this snapshot failed to decode even though they were good SNR-wise. Perhaps
the wobble is the reason for this?

BR and good luck with further QRP testing!

Paul-Henrik, OH1LSQ
