Exactly Bruce
The 4 key words are: With a little more "push" and 'slightly elliptical orbit'
This will not replace in anyway an HEO the ultimate goal but in the mean
time a MEO will give us some releif of our dull environment.
P.S. Dull in the sense of the same usual earth path!

Hello Bruce
I missed also something of this discussion. I'm only a digest-reader
of the AMSAT-BB mails. Sometimes its a problem for me when Luc copies
fragments of discussions into the EU-Amsat group.
Domenico's mail was irritating. AMSAT-India does not plan to launch
a new satellite, they are looking forward, if ISRO would be so kind to
offer a new satellite structure for their 2 transponders and a launch
into a higher orbit. I wish the OM's from AMSAT-India good luck and
success for this project.
I'm not a specialist for orbits and rocket launches, but every orbit
is better than a LEO-orbit. I'm aware of that such launches are much
expensive than a LEO-launch. There were thousands of discussions about
HEO-satellites, but Luc wrote a very important thing. If we all AMSATers
do not pull at the same string, we would never have such a fantastic
satellite like P3E in a HEO. I hope my fellows from AMSAT-DL have anyhow
success with P3E and the cooperation with DLR (www.dlr.de).
Thank You for your support of AMSAT-DL.

I am looking for a easily reproducible yagi for 70cm 4 elements.? I
have?been assigned to?make a better link between two firestations where we

I've adjusted the values some to try to prevent or at least slow the
power cycling we've seen outside of eclipse transitions. The reports via
email have been very helpful, even if you don't get an immediate reply.
Please keep sending them if possible for now. Thank you to PY5LF, ZL2BX,
ZS6BB, VK2AYE, and others I may have forgotten, for their excellent reports.
