I seem to remember seeing a recent email mentioning that AO73 is not using
these published frequencies. What are the current uplink and downlink
frequencies for AO73?

John,
AO73's transponder center frequency has shifted from the original
design. AO73 has a linear inverting transponder so knowing the exact
center frequency is not so important. The AO73 satellite also has an
LO that drifts significantly with temperature.
When you operate AO73, you will be dealing with both doppler and LO
drift. Computer programs to compensate for predicted doppler are
useless. AO73 has a nice strong signal but is a challenging
satellite due to normal LEO doppler and the rapid LO frequency drift.
After I reported all this, I can also report that AO73 was my favorite
satellite when I was active on satellites. It was very satisfying to
complete a QSO while chasing a station across the transponder.
I'm mostly on the moon now. No LO drift when doing EME. :)

Hi John,
The answer is really given below and applies to both AO73 and UKube-1 which
both share the same circuitry.
>> (The passband may be up to 15kHz higher depending on on-board temps. Low
>> temperatures give higher freqs!)
Due to power budget limitations the oscillators were designed to use on a
very few milliamps and they experience temperature swings of more than 25oC
during each orbit!
You will notice that EO88 is markedly better in this regard.

Plans for the activation of these four never-activated (as far as I can
tell) grids are coming together. The expedition takes place next
weekend, May 20th and 21st 2017; a long weekend up here in Canada.
I will be driving up from my home QTH in FN03 and will arrive in
Chibougamau QC on the afternoon of Saturday May 20th. There are several
favourable passes on Saturday evening and I hope to spend a few hours
handing out FN29 to get warmed up.
Sunday the 21st looks like a bonanza of great passes! The trouble will
be deciding when to break so I can move to a different location. The
plan at this time is to set up on the FN29/39 boundary in the morning
and operate there for a few hours. Then I will move to FO20/30 and then
FO20/FN29.
More information about operating schedules will be posted here as we get
closer to departure date. I will also post information on my QRZ page
at https://qrz.com/db/VE3HLS
Hope to work you on the 21st!
73,
Ken

Dear fellow bird chasers,
While digging on the internet, I managed to discover better map border files
for use on GcmWin. I initially found them using the Wayback Machine, using
the link provided on the GcmWin website. However, I've found a more
convenient link on the website for MicroCAM,
http://www.csiss.org/map-projections/microcam/ .
Select the link mwdbpoly.zip. In this zip file are several different map
options you can use - I use PCANPROV, PBORDER, PUSA48, PALASKA, PMEXICO, and
PISLAND. You apply these files the same way you select the default map, in
by going to Options, then properties, then to the borders tab. You may want
to experiment with the line width and alpha settings.
Note: these borders are from 1995, and as such, are missing Nunavut, South
Sudan, Serbia, Montenegro, and any other border changes since then.

Dear fellow bird chasers,
While digging on the internet, I managed to discover better map border files
for use on GcmWin. I initially found them using the Wayback Machine, using
the link provided on the GcmWin website. However, I've found a more
convenient link on the website for MicroCAM,
http://www.csiss.org/map-projections/microcam/ .

Content-Type: text/plain; charset=us-ascii
Hi folks,
Is there anybody that uses Orbitron with WispDDE and the ERC -M? I have
mounted and set ( Thanks to Rene ) it to use with the Yaesu G-5500
Azimuth/Elevation Rotors.
I have interfacedi it with the Orbitron and WispDDE softwares but get a
couple of issues:
- When the satellites reach the LOS, the rotators remains in
the last pointing position and does not move to the
parking position as set in the WispDDE rotator settings..
- When i click on another satellite, the rotators moves to the
Azimuth position even if the satellite is not visible from my
Qth.
Please anybody can tell me if I am making something wrong?
Thanks for any help that will be really appreciated.
73's de Enzo IK8OZV

Strange occurrence this morning on Lilacsat,, At 1410 I tuned the satellite
and distinctly heard the beacon ,, Then I tuned to the downlink frequency
and heard my downlink signal very clear and strong for about 30 seconds
after which it completely disappeared and I no longer had contact with the
Satellite. Does the Sat shut off after a certain period or was this some
fluke of the satellite ?? No other stations were present but my downlink
signal was definitely heard !! JACK KC7MG

About ARISS:
Amateur Radio on the International Space Station (ARISS) is a cooperative
venture of international amateur radio societies and the space agencies that
support the International Space Station (ISS). In the United States,
sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American
Radio Relay League (ARRL), the Center for the Advancement of Science in
Space (CASIS) and National Aeronautics and Space Administration (NASA).
The primary goal of ARISS is to promote exploration of science, technology,
engineering, and mathematics (STEM) topics by organizing scheduled contacts
via amateur radio between crew members aboard the ISS and students in
classrooms or informal education venues. With the help of experienced
amateur radio volunteers, ISS crews speak directly with large audiences in a
variety of public forums. Before and during these radio contacts, students,
teachers, parents, and communities learn about space, space technologies,
and amateur radio. For more informa
tion, see www.ariss.org, www.amsat.org, and www.arrl.org.
Thank you & 73,
David - AA4KN
