Welcome to G4BAO's Amateur Radio Website

Updated 26/11/2018

The 2.5W 23cm driver board kits are now back in stock! 

Kits are now available for a 70cm 3W driver designed for  the G4DDK Iceni or simlar transverter. The kit also performs well as a 500mW ultralinear amp for DATV.

Both articles plus prices are on the  downloads  and for sale pages



My RSGB Convention 2015 and 2016 presentations, "A deeper understanding of meteor scatter" and "Moving up to 23cms" are on the RSGB Youtube channel 

 The UKuG Backscatter book is  now downloadable from



GHz Bands Operation from G4BAO

I'm QRV on 23cm terrestrial and EME - my  favourite GHz band, with 400 Watts to a 44 element Wimo Yagi.

On EME I use a SM6FHZ 23cm circular polarised patch feed  to my RFHam design 1.9m dish and run 250 Watts 

Not QRV on 13cms terrestrial as I've got the 50/70MHz Yagi on the mast instead, but I'm still QRV on 3.4 10 and 24GHz plus 2.3, 2.32, 5.7 and 10GHz EME  


NEW!!! Experimental G4BAO Club log search (160m-13cm only)
