Just WSPR hihi
Nice signal from Jim 504 - and Gus 504 + just
the other side of 504 Gary also running with a good
signal from his
The big spread of wspr beacon
frequency's is / will make wspr monitoring a problem
this winter and beyond as the separation falls out side the
bandwidth of the software, the uk frequency, just under 504 was
to make use of the quite window close to the 504
carrier's noise band , just inside the top of the uk 501>504
allocation.
'We' could re define the 'UK' dial
set frequency higher to allow reception over 504 , but
this dose bring with it a strong carrier in the pass band and
the side band noise from 504 .. and will also increase the
possibility of collisions within the uk allocation
should activity increase
Any ideas ?
