An interesting thing
With so many wspr stations running , why in the last
week are there only 2 stations showing as decoded in the
USA , and non other than we2xgr (who has a valid reason) , Im
sure in the past , there was a much higher number of TA
decodes with less stations
Lack of big boys.?
Q Is it true , there is a carrier-in-pass band
de-sensing problem with the wspr decode ?
Not as I have noticed, if you look at my grabber, there is QRSS
using WSPR tones pretty strong adjacent to M1GEO (and others when
they are on) makes no difference at all. This can also be a carrier.
Of course a huge signal can de-sense the RX.

The large ground wave radius on MF has caused problems
with other modes in the past
