Hi All,
Today, 25th of March 2016, the EO-79 transponder has been turned on
for a prolonged period.
The FUNcube transponder subsystem on QB50p1 (EO-79) had been provided
by AMSAT-UK and AMSAT-NL and is a similar subsystem as on FUNcube-1,
but without the telemetry downlink circuitry.
The current software running on EO-79 does experience occasional
reboots. When these reboots happen, the transponder is automatically
turned off and will have to be turned back on by a command station.
The FUNcube team has selected a few command stations to do so, but be
advised the transponder may be off.
TLEs:
AMSAT keps name: EO-79
Celestrak keps Name: QB50P1
Celestrak file: cubesat.txt
NORAD # 40025
COSPAR designator 2014-033-R
Frequencies:
Uplink: 435.035-435.065 MHz LSB
Downlink: 145.935-145.965 MHz USB
EO-79 has been set to only beacon the normal AX.25 beacon every 30
seconds instead of 10 seconds. The beacon frequency is 145.815MHz and
consists of AX.25 frames on BPSK. more details about the downlink can
be found on the ISIS HAM page at http://isispace.nl/HAM/qb50p.html
Just like FUNcube-1, the crystal oscillator circuits exhibit drift
with temperature. This means manual tuning will probably work best.
Lastly, the commanding team availability will be limited over Easter,
so please report the transponder being on or off on the status page of
AMSAT: http://www.amsat.org/status/
It does not appear in the table, but it does in the reporting drop-down.
73 and have FUN

Scott,
I just got fiberglass tubing for my new setup, it's 2" diameter and I put a
1?" inside it to eliminate any flexing.

Another trick for strengthening fiberglass tubing is to get wood round stock
at Lowes or Home Depot that
will just fit inside the tubing. Years ago I found something which was a
perfect friction fit, though
obviously it depends on the tubing. Cut the wood about 2" shorter than the
tubing, and center it
leaving a 1" space at each end. I stood the tubing on end, and filled the
top with RTV. After it
hardened, I reversed the tubing and repeated the process. The result was
lighter than a solid
fiberglass rod, waterproof, and lasted for 15 years until the whole thing
came down in a windstorm.
73s,

Granger sells fiberglass poles.
But my understanding is that it is critical on crossbooms so you don't
distort the pattern. I am not sure it is needed for the mast.
Someone correct me if I am wrong.

Max Gain Systems sells lots of fiberglass tubing in 2ft increments and much
of it is specifically sized to sleeve together. Wholesale down to single
qty. They were nice to work with last time I ordered from them.

I was going to order some from them a few years ago, but they wanted crazy

Years ago there was a test report on the differences between metal and
plastic crossbooms. It was shown that there is no measurable difference
between the two if the antennas are installed with elements 45 degrees from
the crossboom. Here is one of the discussions from 2002...
http://www.amsat.org/amsat/archive/amsat-bb/200206/msg00896.html
I had to drive about 160 miles roundtrip to purchase a 2 inch diameter 12
foot solid fiberglass boom that I used to build my Oscar class station in
1997. Now I use the metal crossbooms supplied with my antenna's in my two
sat stations. If it really made a measurable difference wouldn't Cushcraft
(AOP-1), and M2( Leo pack) used a non metallic boom?
Anyway there is plenty of talk about this in the archives, and if your going
to use fiberglass I would go with the solid rod as it will last much longer
then a tube. I still have mine stored on the ground in NJ, if anyone want's
one, it's free.....

Good morning,
Tomorrow I will activate the National Mall (DZ06) on the FO-29 pass at
1724Z tomorrow. Unfortunately I can't stay for more than the one pass,
but will return several times in the future. The National Mall is
about three quarters of a mile north of my apartment, so I will walk
there with my normal satellite gear (2 Yaesu FT-817s and a Microset
VUR-30 amplifier) and Elk antenna. Since I am carrying everything on
me, not setting anything up, and have a relatively discrete location
in mind, I do not anticipate any problem with the authorities, but one
can never tell! Check my Twitter @xxxxxxxxxx for real time updates.
I will be around 435.865 MHz +/- Doppler.
I will try to activate as many of the feasible NPOTA sites in the
District of Columbia as possible on satellite during the rest of the
year.

Yes, I confirm, no noticeable influence here using aluminum tube cross boom
with the vhf and uhf yagis fixed in X.
Although this may affect if the antenna will be used to other objectives
such as terrestrial DX or EME, not because the aluminum cross boom but
because of the X position.

Lots of ditters, but only heard and worked WB8RJY on the 1437Z pass
over eastern North America. Lots of QSB, but strong signals otherwise
on the 15 degree pass.
I'll be on the next pass at 1612Z as well.

About mid-pass on the ~9:42AM pass this morning, FOX appeared to switch from
the DUV mode to what I believe was high speed. The screen pattern changed
from the usual 2 parallel line pattern (good eye pattern and decoding) to a
multi-parallel-line pattern with brief stops. My tlm program 1.03f was set
on auto. Nothing decoded; no eye pattern. I manually switched to high speed;
same results. What did I do wrong?

By the way, I'd transmit 10-12 kHz up from where you expect to be
based on Doppler calculations. I think I was around 12-15 kHz higher
than nominal.
