Hello Joe,

I just checked 137.777 and I can hear a weak carrier.
I will start my overnight recording right now.

You can transmit anywhere you like, as I can analyse any channel between 100 
and 600 kHz from 
a linrad recording.

With Linrad I can dig deep into the noise using single sideband CW reception in 
a 5 Hz 
bandwidth. In term of WSPR this is 27 dB less noise compared with a 2500 Hz 
voice channel.

73,
Roelof, pa0rdt
