Mal has very good antennas I am sure he can receive my 500kHz QRPp signal although= he has never admitted it.

Lee M0LMH, the Bloodhound, certainly can at 194km 120miles under flat conditions; he= can also set up a Grabber and display my signal.

=A0

So lets draw a circle 120miles radius from IO92ng. Any station within that circle should be able to receive my signal too, given a not too fantastic set up,= I think Lee has described his set up in that way. If they can=92t, then thei= r Receiver or Antenna could be improved and also enable them to receive sign= als from, say the Czech<= /font> Republic.

=A0

Would me increasing my power until I can be seen on the Broad Band Grabbers improve= the performance of their set up, because now they would most likely receive me. Or does QR= O cover for mediocre RX and Antennas.

=A0

A stupid question but no worse than some of the prior =91Stupid Criminals=92 posts.
