Dual Hop SUCCESS! (corrected copy)



This is a time-corrected list to UTC and it adds N4ZQ that was reported by
AZRowe.  This is the last analysis I can do tonight without a divorce...

ISS<==>PCSAT SUCCESS:

This was pass of ISS and PCsat over USA with PCsat almost directlly 500
miles overhead of ISS over Newfoundland.  To make this fit on your 80
character Email, the first copy is a complete Header with the text
truncated and the second list is just the CALL and the DATA part of the
successful packets. These times (except for N4ZQ's time) are within 1 sec
of UTC.

At 19:56:15 or so, PCsat passed DIRECTLY 420 km over ISS and this was
about 100km NW of Natashquan, Quebec.  40 seconds later We got the first
successes that lasted one minute.  By that time the distance between ISS
and PCsat was about 600 km away.  The N4ZQ report was using a different
clock and I am waiting for confirmation of his clock offset.

Although ISS and PCsat were in view over the entire USA, these succeses
occured after most of the USA was no longer in view.  The next pass was
also directly over USA, but ISS had switched back to voice on 145.800
and so no packet tests were possible.  But I did get to talk to Valery
(did anyone record it?).  This is last analysis I can do, without a
divorce.  I cant wait to plot everyone and the tracks and put it on the
web page...

Here is the full text of the successful packets.

KB1GVR>    :=4436.18N/06826.92W-> QSL TEST
KB1GUE>    :>FN42IL/- CQ from Glenn in Bedford Mass. - KB1GUE@amsat.org
WB4APR>    ::ALL      :TEST in progress
KB2M-5>    :=3911.01N/07445.00W`www.qsl.net/kb2m

Notice that packets went BOTH ways.

One other station, KB1EAA inadvertantly got a Triple hop, but with a
ground station inbetween because he had a WIDE on the end of his path
(which we have recommended for better IGate success once the packet
reaches the ground).  But in this case, with ISS also having the WIDE
alias, it went back up via satellite!

[15:54:19] KB1EAA>APK002,W3ADO-1,SGATE,RS0ISS*/1::PCSAT    :HI{9

With the satellites being WIDE also, this is not a good idea (now that I
think about it.. sorry)...

For this pass, I got to the ground station after the pass was HALF over
and  was still able to comand PCsat into power saving mode with the UHF
RX's off and the Transmitters isolated.  Thus, PCsat was fully functional
with enough power for the test!
