PATRICK - ONE OF THE HARDEST WORKIN' AMSAT-TERS>> ... I will have a demonstration using the AO-27 satellite just after 2.00pm ...
I am showing a pass at 1:01PM Pacific - is that the same pass, Patrick?
I will be working it at the Desert RATS HamFest in Palm Springs.

This satellite holds some promise of a decent and doable microwave
technical challenge.
It will be possible to use our 5760 Transverters for a RX only
application, maybe with minor tweaking.
The LO is 5616 MHz, with the RF of 5840 MHz, the IF is 224 MHz, right in
the US 222 MHz band.
Maybe with a bigger dish, and a very low noise figure preamplifier,
optimized at 5840 MHz,
we could be in the UNITEC-1 deep space telemetry collection business.
The DEMI A32 LO with an external 10 MHz reference, can add the
frequency stability needed.
Or maybe Steve, N5AC, can preprogramm the A32 for a 5,840-145= 5,695 / 5
= 1,139.0 MHz
A reasonable challenge this winter morning, as I sip my lukewarm tea at
the dining room table.
But more questions are raised:
1. Keplerian elements are great for satellites, but once UNITEC1 enters
deep space,
what do we use to calculate and predict the path for our accurate tracking ?
2. Is there anything special about the modulation scheme ?

We want to confirm the battery budget by the decrease of the eclipse rate.

HI, All
This evening, at 17.30 utc FO-29 pass over Europe, I had
A nice qso with SP7TEC, OZ1MY and I1TEX.
Excellent signal from FO-29 back.
Thank you very much to JARL Commander Team for
their effort to keep ever FO-29 in good shape !!!

Hello Andy,
Thanks for the comment.
It is always nice to see an orginal photo to compare what
came down (from ISS) in the SSTV mode.
Sadly I could not get the full image because the ISS was
close to LOS.
I hope some others (in countries more east) have catched
more of that image (or others) and upload it via:

My old FT-470 has served me well.

Hi!
I will be giving a presentation for the Mesa Community College
Amateur Radio Club (KM7CC):
http://km7cc.com/
on Saturday, 30 January, at approximately 12.30pm (1930 UTC). The
meeting will be in the TC50 building on the southeast corner of the
Mesa Community College campus:
http://www.mc.maricopa.edu/campus_map.pdf
which is along Dobson Road between Southern Avenue and the
Superstition (US-60) freeway in Mesa AZ. The campus, which is
also the site of an annual hamfest every December, is in grid
DM43bj. Following the presentation, I will have a demonstration
using the AO-27 satellite just after 2.00pm (2100 UTC) outside the
TC50 building.
For the AO-27 demonstration, I will use the club's callsign KM7CC.
After the demonstration, all stations making contacts with KM7CC on
that pass will receive QSL cards for those contacts. Hope to hear
many of you on that pass.
73!
