Hello Hugh,
Saturday, November 21, 2015
Thanks for the details of the small relay.
I think, in view of the number of relays i would need, the voltages
involved, and the price of the things I may have to abandon remote
controlling the antenna usage changeover. It may give me much needed
impetus to erect a dedicated and much higher LF aerial! I am going to
speak with a friend of a friend who is into these big model helicopter
things. he's apparently devised a means of lifting a line into a
branch and releasing it, all done in close up on camera, from the
ground. He may be willing to hook a line over one of my big trees now
the leaves are nearly gone. In return for beer and pies!
The big Russian changeover switch Vinny DL6II posted about looks
interesting, I may e-mail Dominic, F1FRV about where he got it from
how much it was, and how it works.
