On Dec 23rd, during the Cobb Island special event both NW3M and KB3KOW conducted some D-ATV testing. Bob (NW3M) was stationed at the Old Fisherman’s Field on Cobb Island and ran the transmitter. We had a live video feed going to the TX side, running about 6 watts and feeding an omni directional 440 ground plane.
Bob (KB3KOW) then set up his ‘RX’ side which included the D-ATV demodulator, a small HDMI monitor and his mag-mount antenna. As he headed across the bridge, the mag-mount wasn’t working, so he swapped to a 440 Yagi and then proceeded to visit random points in the surrounding area trying to get a good sync and picture.
Based on the above picture, we had success at these five area. The distance for each was:
Test #1: 1335 Ft
Test #2: 2109 Ft
Test #3: .69 miles
Test #4: .67 miles
Test #5: 1.78 miles
More testing to follow….
