Toot

Hams will understand the excitement! Found this while cleaning up a closet. Not sure what the switch does. 300 ohm to 75 ohm balun. Will it QRP? SWL antenna only? I have some 300 ohm twin lead around somewhere. A little doublet maybe?

@VE7WYC Maybe the switch switches between the 300 and the 75 ohms line while the plug is for the receiver.

This would make sense if you see the drawing as description of what the switch does.

@DD8SF @VE7WYC

If you open it up you'll see a very tiny ferrite core balun.

Maybe too small even for QRP?

@on5zo @DD8SF I think so. I don't want to burn it up so it will be RX only!
