Welcome to my amateur radio site.  I'm Graham Kimbell, first licensed in 1964 and living in West Lydford, Somerset (IO81QC). My interests are mainly 6m (50MHz) and 4m (70MHz) – propagation, working dx and homebrew.  I'm also active on 2m (144MHz) and 23cm (1296MHz).  I also go in for contests now and again.

Chairman of the Mid Somerset Amateur Radio Club.
Corresponding member of the RSGB Propagation Studies Committee
Member of the UK Six Metre Group.
Member of the UK Microwave Group.
Keeper for the GB3USK 23cm beacon.

My first 4m QSO was on 9 August 1964 (on AM). My first QSO outside the UK on 4m was with ZB2VHF (Gibraltar)on 3 June 1968.  I've nearly lost track of the number of 4m rigs and transverters I've built - the current one is described on the equipment page. You can read more about my interests and find some historical recordings on the history page.

My first 6/10m cross band QSO was with EL2AV (Liberia) on 18 October 1980.  I started operation on the 6m band proper on 1 February 1986 when the band was released generally to amateurs in UK.  Six is a specially interesting band because of the many propagation modes possible.  I have written articles on transatlantic Es, Aurora and Meteor Scatter.  See the propagation page for more info.
