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.

Brian GM4DIJ returned to his favourite portable location at IO74mu about 8km south of Stranraer, to operate in the 70MHz Trophy contest on 19th July.
Brian's station was an FT847 into a TE Systems linear amp with 100W output. The antenna was the 11-element VHF NFD yagi re-spaced as a 6 element, which was a struggle to erect to 5m in the wind, but at least the wx was sunny.
Valid QSOs: 30
Claimed QSO points: 9224
Claimed # of exchanges: 23
Claimed # of DXCCs: 4
Claimed total score: 249,048
Best DX: G3XDY; JO02ob; 513km.
Mni tnx to Brian for providing this report.
