Mal (and others)
Apparently I missed this local bargain on eBay when the owner decided to QRT his “QRP” vlf station a year or two before we moved up here to Wales. The transmitters and 800 ft self-supporting masts were also scrapped. I would have bought the complete station it was probably cheaper than my present QTH!
What a waste of our national (radio) heritage. Not sure whether my front-end would have survived if the station was still operational though.
On a more serious note - I am looking for sources of a small amount “self-fluxing” wire about 30 swg in different colours for small toroid winding. Years ago Vero produced something similar for their Vero-wire prototyping system and it was very good but no longer available. I have seen something similar but minimum quantities 100 GBP a reel.
