Re: ISS SSTV Project - Computer Breach

Gladly.

 

1.       Yes, MMSSTV is a computer program with remote access ( I didn’t realize that, but clearly others did).  The program, as operated by the control operator, ALLOWS for remote control and reception of an image and apparently retransmission.

2.       Yes, it is running on the ISS under a control operator’s callsign, the control operator is responsible for every transmission from the station.  Should the control operator NOT want to have others control his station, he is completely responsible for the configuration of the station.  I operate numerous repeaters and digital stations, and I am specifically responsible for every transmission that I allow to be repeated.  If something shows up and is inappropriate, I shut down the repeater and don’t repeat it.  However, if I open the repeater to general amateur use, and someone transmits a message, it isn’t hacking, it is use of the system as designed.

3.       No, there are no published instruction saying that one cannot transmit on 145.800 to the program ( that I am aware of, if you have such a publication from the control operator, please share it).  The amateur radio operator used the software as provided, he didn’t access anything that was not made accessible by the control operator, modify any parameters to gain control, or ‘hack’ anything.  He simply used a feature of the software running  on the ISS to retransmit his signal.  By your definition, anyone using a repeater, packet node, Winlink node, etc. is ‘hacking’ because he accesses a remote computer and uses the software running on that computer to cause a transmission to occur.  That…is not hacking.

4.       Interference is tricky.  The user did cause his transmission to occur instead of a preprogrammed static image, but it appears that is an enabled feature of the software.  If I run 200 watts into the local repeater and you run 2 watts, and my signal captures the receiver while yours does not, am I actually ‘interfering’ with your transmission?  No,  it isn’t an offense if I happen to capture the receiver instead of you, it just means that my signal captured the receiver.

 

At the end of the day, the user pointed out an error in the setup on the ISS, if the ISS actually does NOT approve of the SSTV repeat function.  If, as the control operator, they choose to not allow that function, they simply need to disable it and move on.

 

You are way over the top on this ‘hacking’ thing.  They guy simply knew more about the software than the rest of us, and used a function that was enabled by the control operator to get his signal repeated.  No malicious intent, no crime, no ‘breach’,  he used the software as intended.  Unfortunately, the control op should have disabled this function if he didn’t want it used.

 

Have a pina colada, relax, and wait for the next pass.

Daron - Tell me where my logic and thinking are flawed -

1. MMSSTV is a computer program.
2. It is running on the ISS on one of their computers.
3. Someone who is not authorized to access that computer accesses it.

THAT is the classic definition of "hacking." Doesn't need to be destructive. The mere 
intrusion into a computer owned by someone else is a crime - in many jurisdictions 
(including Canadian law).

4. That person interferes with the public SSTV session. And broadcasts his own images.

THAT is where - in many jurisdictions - the crime is treated more severely than mere access. In many 
states in the U.S., for example, that's is the difference between prosecuting for a misdemeanor 
versus a felony.

The ISS' SSTV program has been interrupted due to this breach. There is no defense. Makes no 
difference if he has a callsign and is operating on legal frequencies. This is not a "ham experiment." 
This is an intentional, criminal breach by a hacker.

I'm not arguing hacking or not on 145.800. As a new ham I really anticipate SSTV from the ISS. When someone screws up that opportunity for many other Hams so he or she can say "look what I did" will never be ok with me. Hacking or not, this action is irresponsible.

Hi Clint,
Regarding QSL card:
Never requested one before.
Do I need to send card or just a report?
What size is returned card? I want to ensure a large enough envelope.
What is typical return postage in USA?

Thank you!

Just use a Number 10 regular envelope, self-addressed  and with a First Class stamp, and send off to Bruce!!!

I received two decent images this time. I made a 2-element Yagi which appears to be an improvement over my old Diamond rubber duck.

Mobile Antenna

Clint Bradford
 

I was just asked what I use to work the sats while in the car.

Well, nothing "special." I have a setup that receives well ... and it gets in to 
SO-50 and AO-91/92 just fine - but nothing specific for the satellites.

The Diamond mount is a clean, "no holes required" one. And the antenna 
does not require grounding.

Each are available at Ham Radio Outlet.

Re: Mobile Antenna

Steve wGØAT <goathiker@...>
 

Clint ...So if not using a directional antenna do most fixed and/or mobile stations run some power to make up for the antenna gain loss? I’m new to the LEO FM SATs and still learning. Fun stuff but challenging to get in to these birds when they’re busy with just a HT/and hand held Yagi!

Thanks, Steve/wGOAT

Re: Mobile Antenna

Clint Bradford
 

Yes. Might take 10W with that less-directional/efficient antenna to accomplish what can be done 
with 2-5W and a tape measure antenna ...

Kenwood TH-D72a NOT Discontinued

Clint Bradford
 

A fellow ham brought this post made elsewhere to my attention. An example of how
the Internet "keeps" everything written ... (grin)

NO - The Kenwood TH-D72a is NOT discontinued. Wasn't when the cited poster wrote his 
misinformation - and not accurate today.

The Kenwood TH-D72a remains the only currently manufactured HT that performs well in 
U/V and V/U modes for working the FM voice satellites.

Re: Mobile Antenna

Joe Krepps
 

Oh my...planning on mounting antennas on the goats, Steve? LOL/HiHI!!

Thanks, Clint, for the tip. That's really encouraging. I remember, about 10 years ago, I had my Yaesu HT sitting in the back seat of my car. Didn't know it was on and a satellite pass goes overhead. It was one of the older Yaesu's that was full duplex. No idea what ever happened to it, unfortunately. I got an Icom W32A but managed to dump a lot of water on it - never got around to getting it fixed. Hoping to _finally_ get on with the '817ND + Arrow.

Tnx & 73/72,

Linear Actuator for EL

Brent Crier
 

I'm hoping someone can hear in the group can help me out. I planning on using a Yaesu g-800 for AZ and would like to use a linear actuator for EL. Is anyone using this type of setup? I'm plan on using Pstrotator for tracking. The AZ setup is pretty simple. So no problem there. The part I'm struggling with is the controlling the actuator. Any help is much appreciated.

The actuator I'm looking at is one of these. https://ebay.us/llXAeg I'm thinking either the 18 or 12 inch one.

Thanks,

Antenna help

I am disabled and low income. It's hard to hold my large sat antenna. Can somebody build me an antenna like the ones listed below?
1 2 element  on 2m, 3 element on 70cm

Re: Antenna help

Brad Smith
 

I assume that you are using an Arrow 2 antenna??? An easy fix for this is to find a used camera tripod. $10 max on Craig's List. There is a 1/4-20 screw on top to hold the camera. I have made a plastic "Y" that mounts to the screw and supports the antenna boom, so it is no longer heavy. This also keeps the antenna steady. Let me know when you get the tripod and I will make you the "Y" and mail it to you.  Brad Smith KC9UQR
