MagicBox Automatic T/R Switch for QRP Radios

I’m ashamed to say that I’ve had this kit in the manila envelope since I purchased it three years ago. I’m finally at the point where I could really use the capability of switching in/out a transmitter. This is catalyzed by playing with the SDRplay and thinking about using it as half a transceiver.

The kit is straightforward thru-hole assembly. I’m thinking I will probably outsource the drilling of the front panel to a friend who has better accuracy than me 🙂
