Kanga Kits by Rick Campbell KK7B

I built many kits designed by Rick Campbell that a long time ago were available at www.kangaus.com.
The kits are no longer available but some circuit boards are available at FAR CIRCUITS
Some of the kits I built before I got my lisence and only used them to listen.

40 Meter R2Pro/T2 20 Watt Rig

  • This 40 Meter QRP transceiver I built in 2003 and 2004 using the following kits:

R2Pro Noise Test to measure Audio Frequency Responce
Low End Responceme.
The homebrew 5 watt driver and T/R relay module
LTSpiceIII Model
LTSpiceIII Simulation of Frequecy Responce

MicroR2 and MicroT2 20 Meter Transceiver

Dec 2006 QST ; MicroT2 Compact Single-Band SSB Transmitter by Rick Campbell
I completed building and testing the MicroR2 and MicroT2 boards but have not completed the enclosure and integration, driver, T/R relay etc. I have added the NORCAL FCC-1 frequeny counter and FCC-2 DDS VFO to the enclosure (https://www.norcalqrp.org/fcc1.htm) and (https://www.norcalqrp.org/fcc2.htm) . All the kits notes here have been retired.
Now being retired perhaps I will find the time to finish this project.
The Single and Two Tone tests of the MicroT2 Board was completedd by using a block converter. Audio generated by the Two Tome Tester program (TCube 0.92) was fed to the microphone input from the PC headphone output and the RF output of the MicroT2 was connected to a block Converter to move the RF signal to audio which was connected to the microphone input to the PC. The Block converter is descripted in the Test Gear Section.
