Out of band WSPR transmissions - a gentle reminder.

Just a gentle reminder folks...

Please check the accuracy of your WSPR transmissions, I still see quite a few out of the WSPR
sub band, especially on 10Mhz.

These cause QRM to the QRSS sub band which is IMMEDIATELY below the WSPR sub band.

I think that ALL users of these modern ultra narrow band modes really should think about investing in some
decent measuring equipment before being let loose on the air.

Try properly monitoring YOUR own signals, and you might be surprised !

If you've never heard of the QRSS sub band please take a look here and see for yourself what you could cause
QRM to if your WSPR TX is slightly out.


Or for some good views of grotty WSPR signals in Europe try this:
