Decoded here rank 14432, carrier Eb/N0 = -1.5dB with BER 40.8%,
log file attached.

The preceding carrier also came through well, which Jacek has
already posted the link to.

Nothing detected here, probably the terminator was mucking about
with the phase by 06:00.

Gdynia to Todmorden is 1330km.  Probably that's a record distance
for an earth loop antenna at VLF.   And yes, I think also the first
amateur VLF transmission from Poland.

Well worth the drive on this occasion!
