This is amazing, Paul. To copy < 0.00001 watts across
the pond with the carrier drifting about is an amazing feat.
The daytime signal is used because more atmospheric
noise is propagated at night?

Unfortunately there is now a delay in getting the gps board but
better stability is certainly in the future.

Thank-you for your efforts and monitoring.

Here's a non-coherent average over 8 days of 10:00 to 20:00

Impossible to do coherent sum with this many days, without
GPS frequency lock.

Not bad for 8uW ERP but it should do a lot better with a precise
frequency.
