Hi Chris,

I don't have any suggestions. With WSPR, Opera and EbNaut sharing
the same small band segment, things are a bit tight if you ask me.
But I don't live in Europe with the likes of DCF39 to contend with
and I am sure there were very good reasons for choosing to put all
these modes in the same small segment. :)

137.550 is particularly bad here, but comparing my clear frequencies
to WSPRnet spots for the last week sorted by frequency I don't see
anywhere for you to go that would help here without stepping on
someone. I will never decode you on 550 when that motor speed
controller is doing its thing. Its typical run cycle is 4 to 5
minutes every 30 to 40 minutes but during heavy rain events and
spring snow melt it can run almost continuous for a few days. As for
the new, constant 10-15 Hz wide noise 'hump' hanging around 550-560,
I'm hoping it will get tired of the game and move elsewhere. It
probably doesn't impair me more than 3 or 4 dB anyway.

I don't think it would be advisable for you to move your WSPR
operations just for me. I manage to hear you often enough. When we
attempt a JT9 QSO we will have to figure out a strategy for avoiding
interference.
