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 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 ! !
