160/80/40 Meter Cw Qrp Battery Powered Ham Radio Receiver/ Transmitter

  

This is a vacuum tube ham radio QRP cw transmitter and regen radio. The circuit uses a 12A6GT tube for the transmitter and a 12SK7 for the receiver detector. The 6SK7/12SK7 tubes were used in the old WWII Paraset Spy radio and they work well for a regenerative receiver.
