I've installed fbins on my VLF stream server, it should be much quicker there. Plus, I've altered it so that it displays as it downloads, so it isn't just sat there appearing to be doing nothing. htt

Hi Paul, looks good. I'm using the same waterproof box for the stuff on the tree :-) What type of isolation transformer are you using? Datasheet? Distributor? As soon as the decode of the 3 char mess

Thanks. 5170 will be a good test of the new rx, the current rx is consistently bad at that frequency compared with E. Last night was -11.0 dB at Forest, stacking brings us up to -2.5 dB. PS, the spe

All my receivers use Walters OEP transformers, A262 range which are available from many places. For isolation, A262A6E at the output of the rx's line driver and A262A7E at the house end. The input t

Well, not very good. S/N of the daytime signal is poor and H-field S/N is worse than E-field, as it was with the old rx. But sufficient for some rough measurements. For the first time I put all the
