Hello everyone,
This morning I had a good pass of ARISSat-1 over Hanoi, Vietnam and decoded
its BPSK-1000 for the first time. According to ARISSatTLM, more than 30
frames were sent to the server out of more than 60 decoded. Manually tuning
the CW signal to keep it within range is fun and it was
The FM telemetry downlink was initially acquired at 0014 UTC with the end of
the SSTV transmission. The signal was barely audible.
Transmission resumed at 0016 with S9+ strength, no noise, and the following
details:
- ID
- Greeting in English
- Secret word
- MET = 45 minutes
- IHU temp. =
I'm on the hook for an amateur satellite presentation next week to the
Vashon Island Amateur Radio Club (http://www.w7vmi.org/) and am hoping
not to reinvent the wheel. Pointers to favorite amateur satellite
presentations in .ppt form which can legitimately be re-purposed for
this effort
Hi Giulio, AB2VY
Edusat is a Non amateur satellite ? ..OK ,but it has received an
experimental license on 435.750 MHz for communicating at no cost
into the Satellite Amateur Frequencies without coordination from
IARU..OK ?
It is very strange that Edusat has received an experimental licence
Is anyone using SatPC32 with a Kenwood TS-2000? If so, what is your
Doppler.SQF entry for the transponder. I can not seem to get it to go
into Duplex (Satellite) mode. It goes into Split and, of course, I can
not hear the downlink.

Hi Domenico,
The Gauss website at

says regarding frequencies:
The communication system uses frequencies in the 145MHz band to communicate
from ground to satellite (uplink) and

A couple days ago, I noticed that to get a 500 Hz signal for CW-2 (nominally
145.9190 MHz) to decode the BPSK-1000 signal, I had to change the
unDoppler-shifted frequency on my USB receiver from 145.918500 MHz to
145.918280 MHz, a change of 220 Hz.
This new value have been consistent over a

I have been catching a couple of passes a day for TLM since deployment.
After the initial tweaks, is has been consistently within +/ 20 Hz of the
predicted value. I haven't seen a large jump, though I did tweak it down 20
Hz yesterday to refine my initial values.

Edition 58 of the IARU Region 1 VHF-UHF-UW Newsletter publishes the
notes from the key C5 committee meeting at the IARU-R1 Sun City
conference.
There are a number of Italian repeaters operating in the Amateur
Satellite Service segment from 145.8-146.0 MHz causing interference to
the uplinks and
All,
ARISSatTLM only uses the 48 kHz sampling rate on soundcards, so
that's the only rate your card needs to be able to run at for ARISSatTLM.

Make sure you have any audio or DSP filters switched off, IF shift to

Alan,
For the last week or so we have been observing it come out of eclipse.
I have noted at worst, a very slow 40Hz shift as ARISSAT1 warms up.
I update the TLE's every day for ARISSAT1 (possibly an overkill) but it is
always within +/-20 Hz at AOS that you quoted.

Hi Carl,
Maybe this will work for you---seems fine to me.

All,
I will be traveling through EM47 on Sep 3rd and again on the 5th. I
will stop briefly on both days to provide an opportunity for as many
as possible to put this rare grid in their logbook. I will only be
able to be active on one pass per day.
Planned operations will be via SO-50:

There's way more traffic on the DigitalRadio list and I don't have to go to
it to see the messages - they come to me. That's the biggest problem with
online forums - you have to go to the forum to read the messages. I'm a
member of at least a half dozen forums - I haven't been to ANY of them
This also works fine for the Yaesu FT 847.

Hi Trevor, M5AKA
Thank you for the information.I believe that without the contribution of the
Amateur Radio Community all around the word in receiving and collecting TLM
as well commanding the satellite the success of Edusat will be a operativeor
failure.

Hi Trevor, M5AKA
The problem here in Italy is that our Communication Autority do not
recognize IARU and the IARU band.plan !
In Italy only ARI is the IARU Amateur Society representing ARI members but
here in Italy there are almost 10 different Amateur societies that are not
representing IARU and
22 matches
