Completed Projects [all kits available as of 1st Sept 2010]

FAT5 A 50W+ Class E solid-state AM transmitter that you can lift with one hand! Companion transmitter to RAT5 receiver. [click here for kit pricing]

RAT5 A simple AM receiver for 80m or 160m that does the job. Low cost, easy to build. Kit available. Companion receiver to FAT5 transmitter. As published in 'Signal', May 2010

CLARA UK version of VK3BHR's excellent low cost L C Meter with UK available parts.
Kit now available (31/08/10)

Multi-Rock
A novel stabilised drive source for 80m/160m. Part of the FAT5 project. As published in 'Signal', October 2009.

Netometer I
A small battery powered device to indicate frequency error by means of LEDs in a centre-zero format. Aimed at users of vintage LF transmitters with maverick VFOs or maverick operators. As published in 'Signal' January 2008.

Netometer II
Netometer I update. Includes a centre-zero meter as well as LEDs for error display, and an improved input circuit. As published in 'Signal' February 2010.

Next Up :

TROPIC A (T)ransmit (R)eceive (O)rganiser using a (PIC). Software working. Proto PCB done. Expected Sept 2010. Don't blow your receiver up - sequence your changeover properly!

Future Projects :

DSP clipper May 2010. DSP clipper running on dsPIC development board using method described by G3PLX. Magazine article in preparation.

Auto Remote ATU Most of the parts of this project have been bread-boarded, and the main ATU has been in use for two years. Offers auto-tune using low power DDS signal. This will be fully documented once I get round to finishing it!

Automatic modulation
meter Automatic level setting, with amplitude modulation display for average modulation as well as peak modulation. Design stage. Expected summer/autumn 2010.

CIV-IQ
I first got this working in 2005 and it's high time the world knew about it.
If you own an Icom set, you'll want to own this as well. No, really ...
