3. In the beginning… Dana, VE3DSS/VE3KU, found an annotated photo of Toronto area VHFers in the 1950’s that hints that at least one may have been active on 10 GHz at that time Dana, VE3DSS/VE3KU, found an annotated photo of Toronto area VHFers in the 1950’s that hints that at least one may have been active on 10 GHz at that time Hans, VE3CRU (SK), had Gunnplexers ca. 1980 Hans, VE3CRU (SK), had Gunnplexers ca. 1980 Things really got started in the mid-80s with wideband FM on 10 GHz Things really got started in the mid-80s with wideband FM on 10 GHz

21. The Modern Era Dennis Mungham, VE3ASO (SK), and Don Jarvis, VE2DWG, were the first in Canada on 10 GHz SSB (SSB Electronics transverter, I think) Dennis Mungham, VE3ASO (SK), and Don Jarvis, VE2DWG, were the first in Canada on 10 GHz SSB (SSB Electronics transverter, I think) Next was Stu Beal, VE3MWM, with SSB Electronics transverter – not sure if he ever made a QSO with it. Next was Stu Beal, VE3MWM, with SSB Electronics transverter – not sure if he ever made a QSO with it. Then Bob Golden, VE3OIK, built a homebrew transverter and started working unheard of distances on 10 GHz – the rest of us followed Then Bob Golden, VE3OIK, built a homebrew transverter and started working unheard of distances on 10 GHz – the rest of us followed WBFM on 10 & 24 GHz has almost completely disappeared, replaced with CW/SSB WBFM on 10 & 24 GHz has almost completely disappeared, replaced with CW/SSB
