To all Amateur Radio operators,
This weekend is the biggest Amateur Radio operator’s convention in the world at
Dayton Ohio http://www.hamvention.org/ and the Matanuska Amateur Radio
Association (M.A.R.A.) http://www.kl7jfu.com is having an Alaska version at the
Palmer Train Depot. We will have all types of radios for sale, many
demonstrations, and testing sessions for those wishing to get their first
Amateur Radio License or upgrade to higher class. We hope to talk from Palmer
to Dayton one or more of the LEO satellites.
Below is the latest news on AO-51. AO-27 is supposed to be turned back on
this week, and I’ll post the prediction for five, that’s 5 LEOs at
http://gahleos.obarr.net and http://groups.yahoo.com/group/gahleos
See you in Palmer Saturday,
73, Dan O, KL7DR

All dates are UTC. The mode change occurs normally between 0100 and 0400 utc
on the date shown. The mode will be active from the date shown until the

from the plan I will post a note to the this Echo page on AMSAT.ORG. If a
specific transmitter or mode is not listed on a given day then it will
be off. For example, if TXB (435.300) is not listed during a 38k4 digital
mode period then the FM repeater will be off.

KL7DR's Orbit Calendar For AO-51 May-June 2005
Centered on Wasilla, Alaska.
To pass audio, AO-51 requires a 67.0 Hz tone on your transmit signal
(same tone as SO-50). The uplink freq is 145.920 MHz and the downlink
freq is 435.300 MHz + and - 10 KHz for Doppler effect. The downlink
transmitter will turn on when it hears an uplink signal with a 67 Hz PL
tone for about 1 second. It stays on for 3 seconds after that signal
goes away.
This operation is just like a terrestrial FM repeater with a 1 second
kerchunk filter and a 3 second hang time.

KL7DR's Orbit Calendar For SO-50 May 2005
Centered on Wasilla, Alaska.
At the beginning of each pass, SO-50 requires a short transmission on the
uplink frequency of 145.850 MHz with a 74.4 tone to turn it on for 10 min.
Then it requires a 67.0 Hz tone on your transmit signal to pass audio.
