Hello Graham,

Thank you for the accumulated results of last night's 477 VO1NA OP8 
reception. Results are promising as propagation was rather mediocre.

I find it amazing how well the cheap RTL-SDR V3 dongle worked.

Is the signal to noise figure referenced to a bandwidth of 2500 Hz?
If so, using a 12 Hz filter for aural copy, yields an improvement of 
about 23 dB.

73,
Roelof, pa0rdt
