The Ten Minute Transmitter

 Decades ago, a ham by the name of Steve, G4RAW, conceptualized a CW transmitter in a magazine article capable of putting out up to 1 watt of RF power over the air. It was so barebones that even the newly-licensed amateur, with little to no experience, could throw it together, tune it up, and possibly make a QSO in a matter of minutes. No, not hours - minutes. 10 minutes to be exact. This rig is called the Ten Minute Transmitter.

Listening to DX AM stations

Yes, including transoceanic ones!

Recently, I picked up some TA7642 chips from Amazon on a whim. Originally, I wanted to make a shortwave receiver with an external BFO for a QRP project, but I learned that these chips only worked up to around 3MHz. However, not all hope was lost.
