Prototype of the Half Pint built in a small cookie tin.
The "Half Pint" is a easy to build QRP transciever, built with just 7 transistors. I've had quite a bit of fun building and operating this little rig. I hope you will enjoy it as much as I have.
It features a direct conversion receiver with an active audio filter.
