Well I sure miss the early morning passes thats for sure. I can hear it about
as well as SO-50 now without the fade like you said John. Thats using a Diamond
10 element 70cm and 9913 coax for receive. Been having a little trouble goin in
with 3 watts, thats what my meter says anyway. I did get

Greetings.
Another observation from DO33 (yo Bernhardt), I've always had trouble
hearing this bird well enough to work from my home station, as I have my
antennas at fixed elevation, and manually-rotated via channelmaster... AO-51
has been consistently easier to hear AFTER it has passed overhead on
a
You are on-the-nose John.
Currently, I AOS and LOS AO-51 at higher elevations than before the initial
flip. During high passes, the downlink is no longer DFQ or is as strong as
before, and there are more fades (was better with leaves still on the trees!).
I have questioned my antenna calibrati
Thanks for the reports.
Again, I encourage you all to research the power levels OUT at the
comparison times. That has to at least be considered in the
discussion.
For example:
Power is "watts" out
Date 435.150 435.300 Battery V
Before flips

By the way, John--a handy place to spot check power levels at various
dates is here:
http://www.amsat.dk/oz7sat/tlm/view.php?sat=ao51 Just put in the
dates you want to see.
And the full telemetry archive is on the AMSAT FTP server, so folks
can grab, decode, and and analyze anything they want,
Hi John,
Have you looked to see what power levels we were running at the
comparision times? Maybe that's part of it...
The orientation should be "back to the way it was" before the flip
experiments. What might be differnet is power budget and therefore
signal strength.
Anyhow, it's good to ask
