Received in Todmorden.

Daytime 18th: 13.9 dB in 34.7uHz, -64.6 dB in 2500Hz
Daytime 19th:  8.0 dB in 34.7uHz, -70.6 dB in 2500Hz

Nighttime S/N was too weak to measure reliably.

Overall: 16.04 dB in 5.79uHz, -70.3 dB in 2500Hz

Overall after adjusting for 30 deg day/night shift:
         16.54 dB in 5.79uHz, -69.8 dB in 2500Hz

Best decode of the 48 hour carrier:

16K25A 90 second symbols, 13 chars at Eb/N0 = -0.4dB  BER 40.3%
