Awesome. The ack messages are automatic and generated by the aprs software or tnc. The number matches to a message number that is tagged on the end of your message and is hidden by the th-d72, but you can see it in the raw packets. The ack tells your th-d72 or other software to stop retransmitting the message. I look forward to seeing more videos like this!
Ah thank you! That makes perfect sense, what the numbers at the end of the ack are for. I don't have auto reply enabled on my TH-D72a. I think my next video will be a "UHF ISS Digipeater TH-D72 Programming Overview" video. I explained it, not step by step, but I showed all the relevant settings. after I recorded my first UHF ISS digipeater video. Did you see that? ruclips.net/video/woSzJ-PtH2M/видео.html 73, John Brier KG4AKV
Your video inspired me to give it a try. I don't do much radio anymore but it was good to get back to it. Programming was easy, of course, I used the Kenwood software to do it, so that saved a lot of time. Heard 10 stations, including the ISS, my position and messages were digipeatd a few times, but it doesn't look like any of the recipients heard the messages, because, no acks (didn't see any acks via the Internet feed) If you would like to try a schedule anytime over the next few days, you can e-mail me first.last name that you see here at gmail.com. 73 de Joe NE3R
Glad to hear you got through. I have yet to use the software, but I'm considering using it to backup my settings, reset the radio, and then show step by step how to program the radio for this by hand. I prefer using the radio over software. I'll let you know about a sked if I can do it.
I have never tried packet. After watching this video I am going to give it a try. I do believe my Kenwood TM-V71A will do packet operation. Thanks for the video, a few years old but still very useful.
The TM-V71A does not have an internal TNC so you would have to provide that functionality externally. That can be done but I don't have experience with it. There are Bluetooth/android interfaces for example. The TM-D710 has an internal TNC though.
I had my very first packet digipeated via 2-meter ISS Digipeater about a week ago. All the steps covered in this video seems quite familiar for me too. :) I am using handheld without APRS built in, all packet work is done by software, the same UISS program (and UZ7HO Soundmodem). Very important thing when using radio without APRS capabilities is to properly adjust audio level that goes from computer to radio (TX). It is quite touchy thing, at least for my VX-6 but it make a difference between not getting into the Digipeater with 6-element Yagi antenna versus QRV with a 40 cm (16 inches) whip (RH-771). Again, I am talking about 145 Mc frequency. DE YL3GU, Marcis.
Congratulations! I have really been enjoying IO-117 / GreenCube for digipeating lately. ISS passes are so short. With a handheld it is tedious to hold antenna and send packets.
CQ short hand for seek you long before ICQ was an internet thing. My first digital satellite contact was using MIR.. One time I happened to catch the cosmonauts live, but was to late to respond before LOS.
Congrats on the 1,000 subscribers and the new video, John! Would love to see you do a tutorial video on the UISS software since I have yet to be able to find one. (I have the Pro version of the software but have yet to try to dig into it so that I can use it with the ISS.)
K3RRR Thanks! You're the second person to ask for a tutorial on UISS. So far I've only used it to receive, never send. I think I could trigger TX from UISS to one of my radios using VOX. We shall see...
Fluffy 3D It's not for everyone but the one thing that makes ham radio different than the internet is the considersble lack of infrastructure required to talk to people. Ham radio satellite comms obviously requires a satellite and that is not a trivial amount of infrastructure but in ham radio we also have HF (shortwave) where we can bounce signals off the ionosphere all over the world with zero infra inbetween each station. Even our sats are relatively simple and are probably easier to maintain/more dependable than commercial sats. There is also the fun with having to build/configure/learn in order to make it all work. Some people sew crochet their own garments even though they can buy machine made ones easily.
John, congrats on 1000 subs. I've been using a tripod from the start, and have found its easier to tilt the entire rig on 2 legs to get the max el on 90 degree passes, then I rotate the entire rig 180 degrees to track the decent. Still not a single contact, I think my sorry excuse for radios were to blame. My first try with my new 710 got me into the iss digipeater on the first try, though.... Hope to contact you on the air shortly.
Thanks Roy! Interesting technique there with the tripod. That makes sense. If I were to use one to track most of my passes I would want to get one that had 360 degree control. Right now mine is a photo tripod, I would want a video tripod to make it more easy to control (one handle to move left/right and up/down). Congrats on the D710. I would love to have that. I have the TM-V71 and it has the same radio/base, just with a less intelligent control head. Apparently you can buy the D710 control head separate and hook up to the base that comes with the V71. Very smart design Kenwood did. I hope to work you soon too.
Hey. Great video. Have you done a precursor video before showing set up. That would be cool. How did you access that pre written message on your ht to tx. Thanks. Wade VK1MIC
Hi, love to watch your video's about packet-QSO's via ISS or other satellites and just subscribed to your SpaceComms channel. In a video you said you had to change the frequency manually (doppler shift) with the portable you used at that moment. I wonder what portables you have that change the frequency automatically. Do you know if the Kenwood TH-D74E (74A in America) has this function onboard? Couldn't find anything about that in the manual. I wonder how the portable knows how to change the frequency. I guess it has to know the pass of the satellite (depending on your position) and it also has to know your position. Or maybe you have to calculate it on the computer and program it to the portable. 73, Peter - ON5US
Peter Bruyneel Hi Peter, Thanks for subscribing. I didn't mean to suggest some handhelds can adjust frequency to compensate for doppler shift automatically. In fact I am almost certain none will. Not aware of any you can control the frequency of via a computer. For FM only radios it is usually manual compensation. Not an issue normally as for 2m you almost don't have to change at all, and 70cm you only have yo change a few steps through the whole pass.
I have the same HT as you and man I wish there was a tutorial on (1) how to get it ready for the quick paced navigation you will need to do in real time in ISS QSO, (2) best messages / text to store to make it easier, and (3) a webpage with screenshots for making UISS and soundmodem work with ISS
My next video will likely be "UHF ISS Digipeater TH-D72 Programming Overview." After I recorded my other video, "New UHF ISS Digipeater!", I showed all the relevant settings I made on my TH-D72. It's not step by step, but it's a good start. As for messages, I just have two "phrases" stored. Basically a "Hi this is KG4AKV, do you copy?" and "73 thanks for the contact." When I made this contact I didn't even use the second one. To make a contact, all you really need to do at a minimum is send a message to someone, and then have that person respond to you. APRS includes callsigns. But you can make it more complete if you want to with more stored phrases. UISS and soundmodem aren't too bad to setup. You just start Soundmodem first and then open UISS. I think I had to change one setting in UISS preferences to make it connect to soundmodem.
Hello, I know this is a little old, but hopefully you're still checking comments. Do you have a resource that explains how to send the APRS messages? I have several phrases saved in my D72A, but I can't figure out how to actually send them...

Jordan The radio that powers it barely functions. They are sending a new one up this year but it will also have a crossband repeater which they may use more than the digipeater. We shall see.

Is it possible to APRS Voice using the ISS digipeter?
Robert Chambers I don't know what APRS voice is. Is that a thing?
I'm referring to aprs voice alert
It's just a digipeater like one on the ground except it's much higher. From my brief reading of APRS voice alert it seems the concept is for facilitating local communications while driving down the highway. Mostly it relies on simplex APRS packets with CTCSS. The ISS digipeater doesn't use CTCSS. A digipeater that covers an area thousands of miles across would probably not be best to use for people trying to find each other that are less than one hundred miles a part. The main use case for the digipeater is what you see in this video.
