When I was 17 I took part in the first foundation course run at the Paisley YMCA Amateur Radio Club in January 2002. My first call was MM3CJM and along with around 30 other people, we were one of first stations in Scotland to obtain the foundation license.

I sat the second last City and Guilds Radio Amateurs Examination (RAE) at the Mid Lanark Amateur Radio Club in June 2003. I then got my current call MM1PTT, which at the time was a ‘class B’ license. The Morse requirement for a ‘class A’ license was then dropped by the Radio Agency and I was allowed to apply for a class A call in November 2003. The call sign I took was MM0IBM which allowed me full access to the HF bands.

Ofcom then finalised the licence structure in the UK so my MM0IBM and MM1PTT calls both had the same privileges. I preferred MM1PTT call so continued to use that call and let the other two lapse.

I held the call sign LX2CM, between November 2009 and December 2010
From January 2013 to June 2018 I operated as M1PTT from IO91ij

NOV Holder and SYSOP for MB7UCM APRS packet iGate.
