Re: AO-40 range record ??

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. 73 Bob W7LRD Seattle ----- Original Message ----- From: "i8cvs" <domenico.i8cvs(a)tin.it> To: "P.H." <bbjunkie(a)f2s.com>, "AMSAT-BB" <amsat-bb(a)amsat.org> Sent: Saturday, March 19, 2011 9:40:47 PM Subject: [amsat-bb] Re: AO-40 range record ?? ----- Original Message ----- From: "P.H." <bbjunkie(a)f2s.com> To: <amsat-bb(a)amsat.org> Sent: Sunday, March 20, 2011 2:17 AM Subject: [amsat-bb] AO-40 range record ?? > 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 > > 73 > > 2i0VAX > > Pete 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 http://www.qrz.com/db/ZL1AOX 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 ! !

I have been trying out the Elk and have a question on polerization. I have been using a Diamond vertically, does the Elk matter vertical or horizontal? I just saw a post and the gentleman said he was using it horizontaly... It definatly is not as good as my brothers Diamond, but was wondering if I was killin any signal strength? Thanks Kevin KF7MYK
