Exactly.? This is not a government.? It is an internet bulletin board system

its custodian believes message moderation is needed.

Hello,
Does anyone have a detailed system diagram (or interconnect drawing)
showing how they have remoted a satellite station please??? Specifically
which parts of the system require IP-addressable power on/off, etc.
I am in the process of constructing a new satellite station for U/V
linear use at Milwaukee Area Technical College (where I teach).?? Our
Data Communication and Networking class introduces satellite technology
which I plan to demonstrate live.
Because the hours of access to the building are limited, and because we
teach Data Communication and Networking from two campuses (but have
Satellite station at only one), remoting this station would be desirable.
I have an APC IP-addressable power strip (117vac) and some power relays
if we need 220vac switched, an IC-9700, two high-power switchable LNAs
(2m and 70cm), antennas (20 element RHCP for 2m and 16 Turn G3RUH Helix
for 70cm), and a Yaesu 5500 rotor with Green Heron Az/El controller
(I'll bring Heliax from home to get to the rooftop).?? Hopefully our
city campus location is not overly noisy.????? I plan to construct the
HEO-ready station as soon as I can be back on campus to do this.
One specific area of concern: how to pass audio over internet. I've
heard Skype and some other vehicles have problematic latency but I have
yet to remote any station to use 'near real-time audio' for CW or SSB
QSOs so I lack experience with this.? The satellite computer
(controlling antennas and managing Doppler) is a Mac mini running
MacLoggerDX and MacDoppler software.
If helpful, I have two surplus new Raspberry Pi 3s (new and unused) that
could be repurposed for part of this if helpful.
You'll be happy to know I've been reading the mail and I know to first
listen and test so we Tx with minimum power.? But as a satellite newby,
I'm sure I'll need abundant guidance when we get QRV.
Any detailed system diagrams (could be off-list directly to me) showing
how you built and configured such a remote station satellite system
would be greatly appreciated.
Thank you
very 73,

Hi! we have the same issue to want to be solved, but with an Icom
IC9100. I saw an Icom Software
(https://www.icomamerica.com/en/products/amateur/hf/rsba1/default.aspx)
for our case, maybe can work with your 9700 too. We dont try it because
for the COVID dont access to the station to try it.
BUT we are still searching an alternative with raspberry pi, to remote
control all the station (Rotor, Equipment and audio exchange) so if you
find an alternative, please share with us too.

K8YSE wrote an article of his remote station configuration in the
January/February 2014 AMSAT Journal. An archived copy can be found at

AMSAT members can view the article entitled "An Internet Remote
Station" by John Papay, K8YSE, in the January/February 2014 issue of
The AMSAT Journal: https://launch.amsat.org/The-AMSAT-Journal-2014
Obviously technology has evolved somewhat in the past six years, but
that should get you a good start on what needs to be considered.

dear Mati:
Thank you.. I will share any details discovered!?? If nothing is out

Yes. But that's not the argument. You rendered it as if the moderators
would step in and act somewhat opaquely - the members need not agree. The
reality is that they should, and probably will, act according to published
rules which we are all aware of. Like a government, and as imperfectly.

Brad,
What transparency and progress has been brought to the organization
from the members that you speak of? Specifically? It appears that
since they were voted in, everyone in the organization is now walking
on egg-shells. The BB is now plastered with emails asking which words
mean what feelings, name calling and chasing after the organization
using whatever legal means the wizards-of-smart can conjure up all in
the name of almighty, all-righeous, '''transparency'''. It all seems
rather insincere and unproductive to me. People like this should do
the organization a favor, and leave, run their own competing
organization and take whatever people and dollars happen to follow
them.
I would honestly like to return to the ARISSat-1 days, where it was
just full-speed-ahead engineering and not all this talk all about
'saving AMSAT' and ORI garbage. All this ORI promotion on the BB, is
absolute garbage. No rational AMSAT member should be OK with that,
especially from an AMSAT BOD member. ORI is a separate, competing
organization and their bylaws are..... telling. If AMSATs bylaws were
ever amended to be anything like those, you can kiss your membership
goodbye, ref: https://openresearch.institute/organization-documents.
Their bylaws literally say "Membership shall consist of the Board of
Directors.". Quite an Open organization, indeed!
But I digress... The more of these kinds of people you vote in, the
more the organization is going to be hurt, guaranteed. Because not
only is nothing going to get done, obviously some people don't want to
work with them for whatever-reasons and THAT actually is important.
And, the reasons are important too. Have you wondered why...? I do!
As a small business owner, when I hear such-and-such doesn't want to
work with so-and-so, I immediately want to ask "What happened"? From
what the email traffic looks like, it seems like you may have to worry
about legal action for everything you say or do around them or, maybe
there was some pre-election history that most of the people that voted
for them, didn't know about. I have no clue, but this all does make
me wonder.
Either way, it seems like the state of things right now is Much Worst
than it was prior-to the last election, so... Not sure why anyone
would want more of this. For me, the socio-political environment is
just as important as the engi-nerding portion.. At the very least,
BOD members need to be promoting the organization they are on the
board of and noone should have to worry about legal retaliation over
every little thing.

Study SatNOGS. I haven't looked for a while and it was mostly receive-only
when I did, but they have hardware and software to make a good start. Plus,
any remote station should participate in the SatNOGS network when otherwise
not in use.
