GK4LOH received over 3467 km on 144 MHz



Delighted to announce that a reflection from the structure of the International Space Station enabled a 144.175 MHz signal from Tim GK4LOH in Cornwall to cross the Atlantic

At 02:40 UTC May 24th 2016 ISS Flypast. Signal heard 2 minutes 45 into the recording and continued for over a minute. The transmitted message was "GK4LOH GK4LOH T T T T T T T T T T"

I'm delighted for Tim as I know how much work he has put into building his station in Cornwall, Tim is a fellow contester with us at the Blacksheep Contest Group and this is a fantastic achievement by Tim also highlighting that maybe the infamous IRTS Brendan Trophy Award is within touching distance after all :-)

A video can be seen here of the moment Tim's signal was capatured:

In July 2014 the RSGB VHF Manager John Regnault G4SWX received a Canadian station VC1T on 144 MHz which on investigation was also found to be by ISS reflection, The ARRL report a group of Amateur Radio operators from Atlantic Canada are operating from Pouch Cove, Newfoundland, until July 12 in a bid to complete a 2 meter transatlantic contact and claim the Brendan trophy.


The "Brendan Quest" team was on the air as VC1T from grid GN37os on 144.155 MHz. The group activated on July 4th, and a couple of days later, on July 6th at 13:41 UTC, G4SWX John was able to completely decode an FSK441 transmission from VC1T.

“They attempted to complete the QSO for 4 hours, but were not successful,” the team reported. “However, this reception could qualify for the Brendan Plate.” The team said a station in Ireland was able to copy parts of three transmissions. Because of the initial success, the group now will use FSK441 exclusively in its Brendan bid.
