Another interesting situation involving AO-40 (sobsob) was when running full duplex there was a very noticeable delay while monitoring yourself. Figuring the round trip distance and the speed of light. I had to turn down the volume a little as I started talking sort of strange. Damn- there's got to be a way, maybe pool all our Visa cards, if I win the lottery I'll buy a launch. There are a lot of very smart and "connected" people in the various AMSAT organizations around the world. A HEO does not have to have every bell and whistle we can think of. Keep it simple stupid (kiss). Our DL friends seem to have the best (only) design. I spent some time looking over my old AO-40 QSL cards (sobsob). Someone mentioned they took some equipment for DX-peditions. A HEO provides an very reliable platform for emergency coms. I could go on and on, but I'm preaching to the choir. I still have my L & S equipment functioning. I'll remove it when they pry it from cold dead hands.

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 ! !
