I don't think that the licence regulations have any say on what
constitutes a contact or actually try say so. That's for the ham
community to decide. I can speak only for the Spanish and UK
regulations, which are the ones that I've ever read.
The EME and meteor scatter communities have a very clear idea of what
constitutes a contact for them, because they're only always working
under marginal conditions, so they try to send the least information
possible.

I agree with that. For me, the worst problem in FM satellites is people
calling over and over without being able to hear the satellite. It would
be fun to record some passes and study how much time gets wasted with
such issues and how much time is used to actually make QSOs. I have the
impression that more than half of the time gets wasted usually.

Ofcoms reasonably relaxed, its main concern is that I identify at the
start of a transmission (CQ) every 15mins or again if I change
frequency. IARU says that a valid QSO is defined as:-
- Mutually identified each other
- received a report and
- received confirmation of a successful identification & reception of the
report
Report could easily just be the Gridsquare on its own, after all the
signal reports meaningless via a satellite if its FM (probably ssb
too) and you're getting into it thats all that matters, remove the
signal report and you speed up the QSO and that extra two letters
doesn't seem so bad.
When you think
EA4GPZ 2E0SQL
2E0SQL IN80do
EA4GPZ IO91js
and a quick Thanks/73
Probably isn't going to take that long.
But I honestly don't feel that because on EME or M/S its just 4
characters that it should mean a sudden switch, for EME/MS the 4
letters have been decided based mainly on the digital modes which has
moved into HF with JT65 and JT9 before then apart from in a PSK brag
file you never really heard QRAs on HF.
I'm not sure how long the 6 characters has been a thing on the
satellites in Europe, but in the 4 years I've been on it's certainly
the norm.. like you say tons of times wasted on for example SO-50
having to wait for someone to stop calling over you or keying you out
that its easily 50% of the time lost just to people probably not being
able to hear the satellite in the first place.
Just my thoughts anyway and many thanks for the squares while you've
been on from the UK.

Content-Type: text/plain; charset="UTF-8"
I'm of the understanding that the Chubusat-1/2 satellites that were just
launched on Feb. 17 will be transmitting telemetry data in 9600 baud
GMSK, in KISS protocol.
With satellites in the past there have been programs written to decode
and save this data in .kss format, but I can't seem to locate any such
programs for the Chubusats. Does it require its own program, or is there
a general one that would be used for this purpose?
I have a brand spanking new FUNCube Dongle Pro+ and want to DECODE ALL
THE THINGS!

I am trying to repair a Mirage KP-2 series mast-mount 2M preamp. It is
quite old. Also, I have the companion bias-tee or Control Box as Mirage
calls it.
It comes in a black plastic box with the hardware to mount it on a mast.
Testing indicates the relay works and some transistors have a voltage.
Unfortunately testing also indicates its an attenuator. I think it has a
blown gasfet.
The small round gasfet has 4 leads and has the following markings on top:
K183
R 43
The PCB is marked KP1&2 Rev B. The
Have any of you repaired a KP-2 2M preamp?
Do any of you have a schematic diagram of this preamp?
Do any of you know the part number of the gasfet transistor? (I'm thinking
its the problem)
Any help would be appreciated.
Thanks & 73, Larry W7DGP

Clayton,
One issue in using magnetometers for azimuth determination is the fact that
the sensitivity to bias and scale factor errors increases when crossed
instruments are used to measure the field. In a system I designed in the
past we used a single axis magnetometer and rotated it to null out the
reading. The angle to the magnetic field was measured by the angle of
rotation required. The instrument was mounted on a ~ 1 ft. plastic shaft to
isolate it from the rotation motor and other sources of error. You could
mount the magnetometer on a simple stepper motor rotator and get better
performance as the expense of some complexity. But it might be a fun DIY
project. Another thing I could offer is I do have some software which
calculates the vector field at any location from the current geomagnetic
field model which is available on the internet. But you can do just about as
well with any current aeronautical chart.
BTW - Thanks for our QSO of earlier today on AO-85.
Regards,
Al Watts - AF5VH

Has anyone ever mounted a mutli-axis accelerometer or a magnetic compass

I'm currently using Hall Effect sensors but experiencing several degrees of

I'm in the process of replacing the bulb inside a Yaesu G-500A elevation

The bulb (28v 40mA) is available from Radio Shack.

Dear all;
Thank you for your reports after the launch.
But ChubuSat-2 and ChubuSat-3 are still in critical phase.
So, we still need your beacon or 9k6 report so that we know
status of both satellites.

Amazingly live video was detected over Australia today, presumably it
was still on over USA!.
Here is a link to the video I received today (in Europe)
https://www.youtube.com/watch?v=j183BLrTZd0
No audio was turned on.
It is expected there will be two more video downlinks next week:
Istituto Sobrero, Casale Monferrato, Italy, direct via IK1SLD
The ISS callsign is presently scheduled to be OR4ISS
The scheduled astronaut is Tim Kopra KE5UDN
Contact is a go for: Thu 2016-02-25 09:10:55 UTC 40 deg (***)
Norwich Schools, Norwich/East Anglia, UK, direct via GB2CNS
The ISS callsign is presently scheduled to be GB1SS
The scheduled astronaut is Timothy Peake KG5BVI
Contact is a go for: Fri 2016-02-26 14:43:39 UTC 29 deg (***)
>From now on we should expect a video downlink all over the world,
before and after any European school contact, and possibly any time.
I have posted more information on the dedicated HAMTV mailing list:
https://ca.groups.yahoo.com/neo/groups/HamTV/
It is likely USA Hams should be able to receive video during the setup
pre-european contact. There is info on the equipment recommended here:
http://www.ariss-eu.org/columbus/ham-video
Please ask if you have any questions. I managed to receive a signal
before with just a dish handheld without any rotator. Ideally we would
like a group of 4+ USA ground stations spaced apart to give 10+
minutes of constant video, or if you can get a commercial 2m or 3m
tracking dish that would need less ground stations.

Thanks to everyone who worked hope on S0-50 just now. She is at ODU in
Norfolk, Virginia doing demonstrations for kids who are coming to tour the
