Each year South Bay Amateur Radio Association (SBARA) hosts a "Radio In The
Park" event, at Fremont Central Park.
The event attracts both hams and public alike and runs generally from 10am
to 4pm. Several portable stations are setup and operated, like a tailgate
party.?

I plan to setup a portable satellite station with a tripod and plan to work
the FM birds at that time. We will be encouraging and helping hams in making
their first satellite contact.

I'm sure the passes will be quite busy on Saturday, but please look out for
operators from CM97.?
Thanks in advance.?

Very nice Terry, but you forgot CAS-4a  :-)

I work with pre-defined sat pairs to avoid Wifi spikes. Here are the
results for some of the common birds using our downlink and your uplink
(predicted) vs. what our uplinks really are for perfect audio.

CAS-4B 145.918  435.287  Actual: 435.285.900
XW-2A  145.672   435.043  : 435.042.600
XW-2B  145.733   435.107  : 435.106.800
XW-2C  145.798   435.167  : 435.166.800

Very solid agreement, tnx so much. It would have saved  us a lot of time
setting up the first time, had we had you nice program.

Please add CAS-4A when you get time.

Two other points. There is a 1200 Hz error on CAS-4A....a few hundred Hz is
predictable, but I think an additional 1000 Hz may have crept in there, so
check your calcs.

Notice all others are no more than a few hundred Hz...which is as it should
be.

The reference freq are for USB, perfect voice tone and fully doppler
corrected.  The Rx are FunCube Pro+ SDRs, that have been calibrated to
within 0.356 Hz @ 10 MHz and checked against 6 meters to be accurate within
3 Hz. (Compared to GPS Discipline Oscillator)

I have an IC-820H on loan till I can afford my own rig. On it you engage
the CTCSS tone with a button, but as soon as you turn the tuning knob it
disengages the tone. This makes it impossible to use Gpredict to control
the doppler shift. Anyone who knows how to make the tone continuously
turned on?

Content-Type: text/plain;	charset=utf-8

Dear All,

I wish to inform you all that the first 3B8 satellite project, MIR-SAT1 is
moving in the right direction as follows:

1) A WEB site is now available (in spite in its infancy):
https://spacemauritius.com <https://spacemauritius.com/>, it has a HAM page
(to be populated).
2) 3B8 Radio Amateurs are deeply involved with the project and this has
already created a new generation of potential HAMs, some 7 (+/-) more
candidates taking the exams in beginning May with at least 5 only due to the
?bird?. In spite the figure may seems low, there are only about 20 active
OM?s in 3B8, thus actually a relative huge progress in terms of potential
HAM population.
3) The first secondary school (college) has built a receiving ground station
last week and already received their first LEO's signals. This is a pilot
project which will be extended to many schools in the coming months and
surely create motivation for hundreds of students to become HAMs, hopefully
we will see the HAM population grow exponentially in the coming months (this
is my personal goal).
4) This project has the full support of the Mauritius Government and fully
financed by the Mauritius Research Council which is a non-profit
organization for the development of science and  technological innovation.
5) The satellite will be launch by JAXA end this year from the ISS.
6) The final design is being finalized and details will be in shared to all
on above mentioned WEB site.
7) IARU coordination will be applied for shortly, as soon as the final
design completed.

I would eventually request the HAM community to help us to collect Telemetry
when the ?bird? launched by end of this year, will keep you informed.

This article was written by a ham and is about hams contribution to radio
astronomy.

https://www.nrao.edu/whatisra/hist_ham.shtmlI think if he was a ham
operator, it would have definitely been mentioned in the article.

Side note... daughter and I got to visit the VLA in New Mexico back in 2016.
(The Karl G Jansky Very Large Array - named for him) The size and scale of
the place is just amazing, pictures don't do it justice. But I do have a
couple pictures posted on my rover profile page that were taken while there.
One of me 'wishing' I could hook up an HT to a dish and one standing at the
foot of a dish. It dwarfs me completely... those dishes are two school bus
lengths across! https://www.qrz.com/db/N4UFO/P

No big issue, just curious if anyone has experienced this.

Now that FalconSat3 is back in Eastern US in late evening before 10PM EDT,
36 minutes earlier every day as Bob pointed out, I'm trying to work aprs
digipeater.

Before, following these excellent guides
https://www.amsat.org/wordpress/wp-content/uploads/2018/03/FalconSAT-Stoddard-
pdf.pdf
 and http://andrewbnortham.com/ke8fzt/falconsat/     I had success.

Then something happened and my TH-D72a just sits there after pressing
"BCON" with "STA" on the screen waiting -  I have ensured, doubled checked,
both A&B if that matters, downloaded with MCP and "Ignore DCD" is the
setting, but it sure acts like it is ON!

Having lots of luck decoding with direwolf, but my handset just won't
transmit when signal is good :\
