A new UK 134GHz DX record was set by Ian, G8KQW and John, G8ACE, who achieved 35.6km on 16 January, over a line of sight path between Cheesefoot Head and Chute Causeway.
Signals were 10dB above noise at best.
The key enabler for success on this extended distance record contact was lower path loss due to less water vapour attenuation courtesy of the low temperature, 2.5°C, and dew point, 1°C.
This was sufficient to overcome the ~9dB increase in free space path loss attenuation over the previous record path.
Congratulations to both.
