Does anyone use the Wouxun RG-UV8D handie for any sats? If so would you mind
sharing your program (.KG) file? Thanks!

I've got to go with the crowd that thinks poor operating needs to be called
out, particularly on the FM birds.
?
The ARRL has called out bad operating publicly in QST since Hiram Percy
Maxim's "The Old Man" rants (their words, not mine) - feedback is a gift -
and if folks don't call it out, it can't improve.
?
I won't go into the issue of old timers repeatedly chatting on busy FM birds
- but will point out there are a number that very patiently wait and listen,
and with a very potent signal call newcomers that are trying to have a first
QSO or two, making the new guy very happy and setting a good example for
everyone.?
?
For those that shy from social media - if you were to look - you'd find DX
operators severely discouraged by rotten operating, and being fairly vocal
about why they don't think it's worth the effort. ?Adrian's post is yet
another example of the same thing.
?
You can't shrug off what's happening with "the kids are new." The kind of
behavior that one wrote about, and that I listened to, was several operators
in a row calling without anyone waiting for the station called to
acknowledge the calling operator. ?Lack of situational awareness is a kind
description of it.
?
Public shamming of a new guy getting his feet wet probably isn't the way to
go, but Paul didn't seem to suggest that except as a last resort. ?Those FM
birds are a very scarce resource, put up there by some very dedicated people
that spent alot of time and effort to make it happen. They are often
available for less than an hour a day each to the entire ham population.
?
People need to actively reach out to folks that need help, in an encouraging
way where it's innocent enough, and in a more direct way where it's
thoughtless or worse.
?
And we probably have to ask ourselves how it is that new comers show up with
so little an idea about what's expected. ?I can't imagine that happening
with anyone from Matt's radio club for example, but if you're encouraging
folks to try satellites, make sure you educate them about how to go about
it, beyond buying an HT and an Arrow and pointing it up.
?
Rant over. ?TOM

Thanks Bernie,
I think you hit most of the highpoints. All operating is about courtesy, it
should be a highlight for us at all times. However please remember that
amateur radio operators are in the hobby for different reasons.
Some folks hang works of art and family photos on the wall, some folks like
certificates. Some folks like to have a conversation on the radio, some
folks prefer to exchange only callsign, grid and signal and do not wish to
talk further. Some folks might be very well technologically connected and
choose (or not) to use that connectivity for amateur radio planning, while
others may prefer to use amateur radio without being dependant on social
media. Some folks sit in a hamshack with multiple radios, computer access,
tracking systems and 'plan' their contacts based on a footprint...others
stand in the yard with a yagi and two handhelds and just work whomever comes
up.
I'm not a contester, but I sure like to pick up a new grid square and more
importantly as one who has roved and done satellite work, I like to share
them when I can be helpful. The satellites are a limited resource, we need
to take turns and let others in.
There have been west coast passes where I've listened to the downlink and
I'm the ONLY one on the pass. I've had passes where I could visit with
someone a few states away for most of the pass, stopping between comments to
ask if anyone else wants in. And I've had passes where I tried for 5
minutes and couldn't squeak my callsign in.
For the most part I think we're all willing to play nice, but certainly we
need a reminder and there is no doubt we need to continue educating people
how to use satellites.

A SAT newbie here.
I would like to set my HT(TH-D72) up pulling audio off the HT for
recording and also use a headset. The connectors for the HT are unusual
(for me). I would like to have users contact me off list (k8pt@xxxx.xxxx
and tell me what adapters, headsets you are using to accomplish this.
Thanks. Sorry for off topic questions.

Patrick,
This is certainly a fine idea, which may very well gain traction.? If
I may, though, I'd like to propose an alternative experiment. Given
the recent (and ongoing) disaster and recovery in Puerto Rico after
Hurricane Maria,I was wondering how amateur LEO satellites could be
used for emergency response (I know that the use case for the Phase IV
satellite terminal is emergency response.).? While DX and chasing grid
squares is great fun (I do both myself.), I am hoping that there might
be a way that LEO satellites could be used as a public service resource.
Traditionally, long-distance emergency response has relied upon shortwave
communications.? It takes a bit of infrastructure cost to set up and
operate a shortwave station.? Effective antenna deployment, available
transceiver equipment, and a sufficient power supply are considerations
to be addressed.? Perhaps, a pair of hand-held radios (or single full-
duplex), an Arrow antenna, and a computer (Raspberry Pi) could be used to
send and receive emergency messages via LEO satellites and might be a viable
alternative.? The messages could be sent digitally via, say, Narrow Band
Emergency Messaging System (NBEMS) to improve reliability of transcription.
I'm sure that you or someone else might say "Use the APRS birds for
emergency response messaging.".? That may be a fair statement, but my
idea might, at least, be an interesting experiment to try.? An experiment
is still valuable when it shows that an idea does not work!

Hi all,
There was a comment on the recent experimenters thread about using the APRS
birds. I'm new at this game - I've made 2 satellite QSOs so far - and would
love to know more. Is there a good document on how to use these satellites,
and maybe some tips on how to get a TH-D72A to do it? I've only used it to
beacon APRS, messaging with the service isn't something I've tried.
Thanks and 73,

Sean,
There are some good resources available on the AMSAT.org website.? I've
listed
a couple below.? I'm sure that there are others that can chime in that have
actual experience workinghe APRS birds.Welcome to the AMSAT community.? Good

Ignore the references to UHF. It's back on 145.825

Hi Mac!
You offer a good idea. I thought about things like that, but
came back to the simple fact that AO-91 still has the "new
car smell" for being the newest and (in my opinion) best
performing FM satellite we currently have. Especially given
the recent series of messages discussing the new document
Sean KX9X wrote, it might be better to hold off on anything
that limits the use of AO-91 to those who would have a
computer or other accessories to do the experiment. Once
we have another one or two FM satellites, Fox-1C and/or
Fox-1D, then it would be a great time to have something
else for the weekly experiments.
The APRS-capable satellites might be better for what you
propose, yes. Unfortunately, there is the issue of the
misuse of 145.825 MHz by stations automatically beaconing
their existence. Any experiment using ISS or NO-84 would
be tougher as you move east across the continental USA,
as well as some other parts of the world.
73!
