Transverting some more, some more


Following my progress last time:

I've kind of finished (ready for test) the Anglian transverter.

And this is my hideous looking changeover relay for the 144MHz socket.

There's an Omeron relay on the underside of the board, even so it looks pretty hideous to me!

These are the things I am not so sure about:

  • The changeover relay - need I say more!
Fun though, egh?
