I think I missed something here? With all the comments about FoxTelem,
I'm not sure. Does this mean with the I/Q output, the IC-9700 can do
9600 baud packet/telemetry? (Curious because this was kind of a deal
killer for me.)

Digital signing images could work, but this stuff takes care to do
correctly and a mistake would defeat all the effort. If someone wants to
design a 'satellite login' system where we verify our Callsigns "Logbook
of the World" style, and then have private keys to verify our identity,
well, that's another project, and best if shared among all future
satellites that want to use it.
I suggest an open command to delete any image.? The images would fall
off the queue anyway eventually, so not much is lost if someone gets
delete happy.

The "need" for some sort of identity for the images is that use case I
mentioned for a live picture frame. When a ham downloads an image or
message from a passing satellite and sees or reads something
inappropriate, it's a matter for that ham and the service. She/he has
existing means to deal with the problem, and the problem is relatively
contained. On the other hand, if the images are automatically
downloaded and displayed on the wall in someone's home or business, then
a significantly larger community can be affected, one with potentially
much larger negative impact on the hobby if it gets out of control. If
TwitTubeBookGram.com had built in the proper safeguards from the
beginning, "social media" would look a whole lot different than it does
today. Mind you, I understand and support the desperate need for
anonymous postings in some countries, but that does not apply to amateur
radio. Simply knowing, in a public and reasonably verifiable manner who
uploaded an image should be sufficient to thwart any abuse, and to
provide a means to deal with it.
I would love to have my imagined picture frame on the wall in the Shack,
or have my PC's screen background get updated with images downloaded
from a satellite as it spins around the world. I think it would be a
great way to show off the hobby, and to support the significant
accomplishments of hams around the world in imagining, designing,
implementing, and operating satellites and the infrastructure
surrounding them. But sadly these days, anything one does that can have
a broader reach needs to be curated in some way. It would be a shame if
such a use for the satellite could be ruined by the lack of just a
little bit of control.

Cathryn,
? If someone wrote the software to use it you could receive 9600 packet
from the IF output but you have no way of sending the reply as a ic-9700
will not transmit 9600.
Talking to Icom (many times) they feel that 9600 is a dead mode but
somehow RTTY on VHF/UHF is not...

Noticing the advert in the Journal and seeing a couple of features that
looks useful I downloaded and installed it.
Questions:? It forced me to uninstall the old version before installing
12.8d.? Once installed I had to reconfig everything local like station
location, rotor and CAT interfaces, display and operational options...
Is that correct or did I miss something that would have made this easier?

I just reinstalled 1.08p and can now decode the WAV file Left, or Right,
Raised Cosine, or Windowed Sync. Decoded 23 23 23 23 packets. Now what's odd
is I couldn't get the WAV file to decode until I deleted 108y, and then
reinstalled it. Win10 build 1903.

Alan,
Just had 95, 91 and 92 go by and all 3 decoded and all 3 decoders
also worked although windowed sinc seems to be the best.
Whats interesting is 1.07Y will decode if you are on the left side or
the right side of the image but 1.08 only works if you are on the
"right" side,
I will leave that up to Chris to explain why that is.
I can go in and tweak the frequency settings to make foxtelem always
look on the right side.

?Jim
? In the manual section E7
The Installshield setup program deletes the data files of an existing
installation when it installs an update and your? personal settings will
be lost. DataBackup allows you to first save your settings via mouse
click and then to restore them after the installation of the update is
finished. If you have a flawlessly working configuration you should also
save the settings with DataBackup.? That allows you to easily restore a
working configuration if errors occur.

I'd like to offer my opinion on this topic, everything that follows is IMHO:
First off.....should we start a separate thread for a conversation on
digital signatures / identification in Amateur Radio? Hopefully this isn't
distracting too much from the main point of the thread for helping to
collect up secondary mission ideas for Drew and the potential new partners.
I'm saying that, because I'm about to dilute the thread with my opinion on
digital signatures (hi hi), and feel bad that I might be distracting from
the main point (long emails......but this stuff is just too cool)......
I'd like to voice my support for the concept of digital signatures for this
type of concept of operation (CONOP) for an Amateur Radio spacecraft (but
not all satellite CONOPs).
This type of operation is probably coming one way or another as technology
evolves with the introduction of more advanced payloads to the hobby,
depending on mission needs......and the sooner we can start trying it out,
and trying to make it easier for hams to use (for the implementers out
there) I think is a good thing. I think I can see both sides of the coin
here.....and I think the trick is the devil in the details and in the method
of 'enforcement'. Amateur radio has prided itself on being a
'self-regulating' entity, and for Zach's example, I would argue that there
are mechanisms in place such as the ARRL Monitors Program that work with the
FCC to potentially self-correct misconduct within the service or escalate
'flagrant violations' to the FCC. For a satellite, that method of
enforcement is much more difficult.....and the methods used to identify an
illegal/inappropriate HF station simply wouldn't work for the image upload
CONOP. Something like a digital signature mentione
d by Cathyrn is one way to create that type of capability for a spacecraft.
There is a delicate balance that needs to be struck between ease of use if
you want folks to operate with something new, but control is also very
important.
When we were working on the GEO (Phase4B) payload back when there was more
momentum, this specific issue came up for controlling user access to the
digital transponder. Remember that one of the main mission objectives was
emergency communications. Authentication of a user was very important for
this, especially for prioritization of satellite resources and availability.
Some folks may remember talk about 'emcomm mode' vs. 'anyone can play
mode.' One idea for what one of the differences between those two modes
would be is whether or not users are being authenticated and allowed access
to the bird. In one version of the idea, when in EMCOMM mode, a 'whitelist'
of authorized users would be allowed to use transponder resources, those
users specifically involved in the emcomm event that needed the transponder.
There were even discussions about whether or not we should *always*
authenticate users, because with a 24/7 GEO resource....well, put simply,
satellite piracy is a real thing,
and we need a mechanism to deal with it.
Without getting bogged down in the technical details of that particular GEO
attempt, I just wanted to say we specifically considered Log of the World
for the mechanism for generating the credentials to identify a user. Having
a single certificate authority for all things 'Ham Radio' is a good idea so
that users only have to create their identity 'once' and not have to keep
doing it for each new mission....LoTW is something that many hams are 'used
to' and is something maintained at a central place familiar to hams. Its
seems like the 'easiest' way to get folks to 'register' for the ability to
access the satellite. Yeah, its an additional step to get on the air...but
hopefully one most have already taken, and one that's not hard to take for
those who haven't, and the payoff for taking the step is access to a really
cool new capability! In this way, we have the ability to lock out illegal
operators (that may not even be licensed Hams) and/or inappropriate users,
and a way for us to
prioritize use for EMCOMM situations......very important if lives are at
stake.
There's a lot more detail behind this for the ideas around how the
authentication process would actually work that I won't get into.....no
actual decisions were made, but a lot of really really good conversations
about how to ensure we can control the resource and keep it open for use to
as many hams as possible with the least amount of burden (for the user, not
necessarily least amount of burden for the designers/control operators),
maximize it's utility during EMCOMM events, and not run afoul of FCC either
through illegal/inappropriate use of the resource that we are unable to
'self-regulate' against but also make sure we don't run afoul of them in the
way we implement the solution (authentication conversations can sometimes
turn into encryption conversations.....no go for Amateur Radio, but all
ideas are good ideas when brainstorming a solution to a tough problem).
Basically, we wanted a way to remove the bad apple from the bag, rather than
spoil the bunch (i.e. turn off the whol
e system) because we didn't have a way to deal with the bad apple.
Summary: I think the digital signature idea is a good one, I think LoTW is
a good candidate for the certificate authority, and I think considering this
type of operation within the constraints of part 97 rules when implemented
helps set us up to keep our spectrum and keep it 'self regulated' as
technology evolves.......and the sooner we start testing/demonstrating these
capabilities, the better off we are.
Again, all above is IMHO.
Sincerely,
-The 'other' Zach, KJ4QLP (N0ZGO is the main 'Zach' because he's getting it
done on Golf!)
P.S. To be clear, I do NOT think we need this type of thing for every type
of Amateur Radio communication or even every future satellite.....for the
image upload example, and the GEO example, I think it makes sense at least
in terms of one option to consider for a solution......there could be other
solutions to the issue.

Subject: Re: [amsat-bb] Secondary mission ideas
The "need" for some sort of identity for the images is that use case I
mentioned for a live picture frame. When a ham downloads an image or
message from a passing satellite and sees or reads something
inappropriate, it's a matter for that ham and the service. She/he has
existing means to deal with the problem, and the problem is relatively
contained. On the other hand, if the images are automatically
downloaded and displayed on the wall in someone's home or business, then
a significantly larger community can be affected, one with potentially
much larger negative impact on the hobby if it gets out of control. If
TwitTubeBookGram.com had built in the proper safeguards from the
beginning, "social media" would look a whole lot different than it does
today. Mind you, I understand and support the desperate need for
anonymous postings in some countries, but that does not apply to amateur
radio. Simply knowing, in a public and reasonably verifiable manner who
uploaded an image should be sufficient to thwart any abuse, and to
provide a means to deal with it.
I would love to have my imagined picture frame on the wall in the Shack,
or have my PC's screen background get updated with images downloaded
from a satellite as it spins around the world. I think it would be a
great way to show off the hobby, and to support the significant
accomplishments of hams around the world in imagining, designing,
implementing, and operating satellites and the infrastructure
surrounding them. But sadly these days, anything one does that can have
a broader reach needs to be curated in some way. It would be a shame if
such a use for the satellite could be ruined by the lack of just a
little bit of control.
