Hi,
For a small club satellite presentation I will be mentioning the benefits of HEO over LEO and the range advantage.
Can anyone tell me the distance record set when AO-40 was alive?
Thanks

Hi Pete, 2i0VAX
My DX record on AO40 from JN70ES Naples Italy was a QSO with ZL2AOX Ian Ashley in RF72MV with a distance of 18299.0 Km as you can see in the following page of QRZ.com
The uplink was in L band and the downlink in S band
This is why it is very important to pull for the new HEO satellite P3-E ! !

which is 11,370 miles. The circumference of the earth is 40,075 km (24,901 miles) so 18,299/40,075 = 45.7 %.
That is darn close to half the earth in the footprint. Compare that with a Leo sat footprint. Anymore questions why we are hoping for another Heo?
