14 -16 May 2021 - GM3HAM/P - RSGB 2m Contest, Gatehouse of Fleet
- Details

Peter GM4DTH and Brian GM4DIJ
Back to our favourite site, on a hill-top near Gatehouse of Fleet.
Peter GM4DTH described the wx conditions as "grey and unsettled".
Radio conditions were below average with low signal strengths being the norm for the entire operating period.
Unusually, we could not hear GB3VHF (144.430MHz).
The antennas were an M2 17-element yagi plus a secondary circularly-polarized antenna to help to work stations with non-horizontally-polarized antennas.

23 & 25 July 2020 - 122GHz - Two Firsts in 3 Days by Brian GM8BJF & Pete GM4BYF / G4BYF - Confirmed by UK Microwave Group
- Details
- Written by Alan GM3PSP
GM8BJF/P GM4BYF/P
Brian GM8BJF reports: Pete GM4BYF and myself have recently built up VK3CV 122GHz (2.4cm wavelength) transceiver boards into portable systems and have been doing some tests with them. On Thursday 23rd July we had what we believe wss the first GM to GM contact across a distance of 0.69 km between two hills in Edinburgh and on Saturday 25th July we went down to the English border and had what we believe to be the first GM to G contact on the band.
Interestingly, Doppler effects were observed even at walking speed on this band (no fire-engine required)!
We were using the system in its most basic form with 25 mm circular horns. Plans are now afoot to add refinements such as GPS locking and improved antennas and try for longer paths having established the basic functionality of our setups.
John G3XDY of the UK Microwave Group has confirmed that these are "Firsts" for GM/GM & GM/G on 122GHz. Certificates will be awarded. Congratulations to Brian and Pete.
John G4BAO has credited Brian and Pete with the GM-G "First" in his GHz Bands page (64) in the November 2020 RadCom & link to Brian's webpage.
