Ok Ed,
There are some big signals about now ,
as for the de-sense , you look to
be reasonably in the clear , but if you
check the station in the deep south and the next
one north , you can see very few stations
listed , where as a touch up the map ,
the numbers ramp up quite quickly
Actually the G3PLX system was far more suited to this ,
with a short carrier burst , very green !

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
