Independence Day, July 4, saw AC0RA and OM3BD set another world distance record using the amateur radio satellite AMSAT-OSCAR-7 breaking their own record set just 48 hours earlier.
The new distance record was 7903.55km comfortably exceeding the previous record of 7849km.
Bill OM3BD in Grid Square JN88mf reports that Wyatt AC0RA once again woke up early and this time drove 150 miles to EN41ad. They had a 30 second contact at 0949Z to extend the record to 7903.55km.
Bill’s equipment comprised an FT847, 2 x 10 element yagi on 2m with SP2000 preamp, and an 8 element Yagi for 70cm while Wyatt had an FT-847, a 7 element Yagi on 2 meters and a 12 element Yagi on 70cm.

The article “Guide To OSCAR Operating” that was published in “The Best of OSCAR News” Volume 1 in 1980 notes that the maximum theoretic range of AO-7 without propagation enhancements was expected to be about 7900 km. In some ways it’s surprising that it’s taken 37 years since the launch of AO-7 before the extremes of range were tested to their limits.
