>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.

Homebrew 30m CW Transceiver by 7N3WVM
This simple receiver was originally intended to check the transmission of my 30m QRSS beacon. By tuning the 30m receiver to Russia's RWM timesignal on exactly 9996kHz I was able to calibrate my frequency counter.

Pocket sized 20m (30m) CW QRP Transceiver by S56AL
I started to discover the 30m band by using an adapted version of my 80m single-board CW transceiver. The first impressions were quite encouraging, so I decided to build a portable transceiver for this interesting band.

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.
