New 122GHz DX Record

UK amateurs continue to create new DX records on the 122GHz millimetre-wave band. On the 7th of April, using barely one milliwatt, a new all-time UK record was set. The contact was between Roger, G8CUB and Chris, G0FDZ, from Danbury Hill in Essex to the Isle of Sheppey, a distance of nearly 36km. This is all the more remarkable given the very low power and high atmospheric loss due to an oxygen resonance that affects this particular microwave band.
