2N2/30 - A 30 Meter, Discrete Component CW Transceiver by K8IQY
The 2N2/30 claims its heritage from the 2N2/XX platform, but also uses non-2N2222 transistor types and commercial mixers. From the beginning, it was to be a test bed for building with surface mount parts in a Manhattan-style construction environment.

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.

A CW transceiver for 30 Meters using 72 components by KD1JV
For the spring 2010 FDIM (Four days in May) design contest, the ARCI (Amateur Radio Club International) decided on seeing if anyone could design a rig using 72 or less parts.

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.

SW30+ 30 Meter CW Transceiver by K8IQY
This 30 meter CW transceiver was built as part of an internet Manhattan-style construction course conceived and taught by my friend Chuck Adams, K7FO back a few years ago.
