30m Band - All BJT Transceiver by YO3DAC/VA3IUL
Reason building this radio is to get a real portable QRP transceiver with low power consumption.
On receive, the current consumption is approximately 100mA, and no more than 1.8A in TX mode, at full power.

Simple 30m Band QRP CW Transceiver by DL2YEO
This simple QRP transceiver for the 30 m band did not result from a detailed requirement profile. I simply had some NE592 broadband amplifiers in my junk box, waiting for an application.
