24GHz DATV World Record

The day after the Wirral mini tv convention, 12 May 2019, it was planned to try to extend the 24GHz DATV distance record with a path from Brown Clee IO82QL and Winter hill IO83SO. M0MHO, G7ACD, G4FRE, G8AQA, Dave G8VZT. and G8GTZ were at Brown clee and the Wirral club G3NWR with G4CBW were at Horrockswood IO83SO.

I had recently upgraded my DB6NT 24048/432 Transverter to use a DB6NT local oscillator. Checking out the system it was seen to produce 2W of DATV when measured on an HP432C power meter. Searching in the loft I found my Practical wireless 18" dish with its penny feed which was pressed into service

After setting up, G4CBW signal was easily seen on 24GHz with a MER of 17dB and both myself and G8GTZ exchanged 2 way signals for a new world record.

The Wirral could be seen to the left of the Wrekin which houses the GB3ZME 24GHz beacon
