Hello Roger, Big earth electrode antenna allows transmitting on 136kHz with average results. https://klubnl.pl/wpr/en/index.php/2018/01/09/most-na-wisle-elementem-anteny-czyli-eksperymentow-z-dipolam

Oh, indeed. Embrassing ;-) Usually i know how a loop radiates :-) Tnx. 73, Stefan Am 24.01.2018 23:10, schrieb Markus Vester: antenna is almost orthogonal to the RX sites of Paul, DL0AO and DK7FC No,
Hello Stefan! Winter is a very good time of the year for VLF tests. It takes 3-4 people to set up a 10 km antenna. When I manage to get that many volunteers – we’ll conduct the tests. 73!
Roger: I tried to post a reply to the group prior but it did apparently did not make it past the admin monitor or it exceeded message size limit. I found the key to getting the FT-817 to receive well
Thanks Mike. I seem to remember that I got surprisingly good results with my EFP (schematic shown a few days ago) feeding into the FT817 on 136kHz, This has not be tried since before my 2013 stroke.

I've found that the thorcom.com servers (which are the MX for blacksheep.org) are not very forgiving of incorrect DNS settings, and also STARTTLS negotiation. Even many "professional" email providers
Hi Jacek on my own checks it seems to be posters out side the UK who occasionally have trouble ( some ISPs are permanently locked out it seems). I also noticed on the turn of the year there are a lot
