What would be a good affordable wire to wind a base loading coil from? It can't be too small diameter or the losses will be huge. That is the only part of the station that seems like a big undertaking. The rest of the components are low cost and easy to build. Mike WE0H Mal wrote: Wolf. Receiving what ? I am not totally convinced. Receiving a signal a few metres away is not what I call a good performance. A few hundred K/metres away on cw is what I expect and not QRS 20,000, where it takes months to send a DOT. It is easy to generate a 9 kcs signal and high power audio amplifiers are plentiful to radiate several K/watts to a loaded inverted L 20 + metres high. This is the easiest band to set up, the only time consuming part is winding a suitable loading coil. Instead of going to Spain or Portugal for holidays I would suggest discerning vlf operators stay at home and wind coils this year. I am staying at home this year in case someone performs a MIRACLE and it could be a German, English man is scared of being heard using HIGH power.
