Offgrid Text Messaging with APRS & SMSGTE- No Random Contacts Series

[@thuff3207]

Just remember SMSGTE is not free. We need to support them to keep this working. It’s a great service.

[@TheTechPrepper]

Thank you for calling this out. It was in my notes and completely forgot. I'm pinning your post.

[@the_mad_swimbaiter455]

Good to know. Didn't realize they needed support, we can't lose this capability!

[@EvanBoyar]

@@TheTechPrepper Very sad to report it's offline (see the note on the project's website). What've you been using to replace it, if anything?

[@attribute-4677]

Please don’t “dog” yourself on what you have to offer. I’ve been a ham and radio hobbyist for 20+ years and I’m still learning things from you. Thank you for your videos and time!

[@colinbaker1512]

Great material Gaston! As a "rookie" I appreciate being on this journey with you and the digestable way you are able to break topics down!

[@TheTechPrepper]

Thanks, Colin. Welcome to the hobby. You are not far behind me. Keep up the good work! It's nice to hear that you're enjoying the format. I'll do my best to keep the explanations as simple as I can. I figure that if I show people what's possible that it may spark enough interest from them to go off and try some of the techniques themselves.

[@chrisherd991]

Buddie I have been in Telco and ham stuff for 30 years. You are doing fine. Ignore the armchair perfectionists who dont get attacked by a plant.

[@TheTechPrepper]

Haha. Thanks for the chuckle. Will do.

[@johnblaisdell2179]

I would not consider this a failure. The fact you have an after action report in the shack is proof positive that you are gaining knowledge and experience. I've been licensed since 2009 and been part of my local ARES group since day one. I see so many that talk and never do anything. You are getting out there in the field and doing and sharing your experience with others and maybe inspiring a few along the way. Keep it up and keep the great videos coming. 73 de W4CJB

[@TheTechPrepper]

I'll keep the videos coming. Glad to hear that you're enjoying the content. Keep up the great work with your ARES groip.

[@markt.3454]

Been doing Amateur Radio for about 18 years with most of my interest split between ARES/Emcomm/Auxcomm and exploring grid down communication options. Even though I've already done many of the things you demonstrate, I really enjoy your channel and the organized, straight forward approach you have in explaining what you're doing. If you were going to use APRS for messaging in the area around your home location, you could always put a digipeater at or near your home, and set APRSDroid for wide3-3 if that's what it took to get to an Igate. Even an old 90's vintage TAPR TNC2 can be linked to about any 2m radio you have laying around to make one.

[@TheTechPrepper]

That's an excellent point. I used to run a digipeater on a RPi 3B+ with Dire Wolf and YAAC. I'll have to connect it back to my FT-2980R and try it with just Dire Wolf. Thanks for the reminder. 73

[@Sean-AI7EQ]

I've used SMSGTE to text my wife when I had no cell service and was stuck in traffic on a snowy pass last winter. It worked great. I run an iGate for APRS for this very reason! Thanks for sharing and I'm looking forward to the next video.

[@TheTechPrepper]

Glad to see others using these techniques in the wild. Are you running Dire Wolf for your IGate? I had my RPi3 setup as an IGate, but haven't turned it on since last year.

[@Sean_Hartley]

@@TheTechPrepper I'm using a Windows machine running APRSIS32. I am not super familiar with Linux and the Raspberry Pi.

You set up the camera before you pulled out the cactus, that's dedication.

[@TheTechPrepper]

Actually, the first set were not bad. There were only a couple of barbed spines attached to my ankle and shoe. The second one, about 20 minutes later, had about 30 points of attachment to my ankle and leg, hence no camera. I wanted that sucker off. We had 50 mph wins come through that scattered the cholla all over the place. They're like cactus land mins. Cheers!

I've been licensed since 2008 and I find your channel very interesting, there are some things I know and don't, but I keep my mouth shut and ears open as I may learn something new. I thank you for your videos and always look forward to the next one.

[@TheTechPrepper]

Glad to hear that you're finding some gems. 73 de KT1RUN

[@AD6DMDennis]

Thanks for the rundown on using APRS with SMSGTE. I have found, like any other contingency comms method, you have to be very patient with getting the message out. Not the best for a live demo, so we understand the breaks in recording and the home AAR's. You're working with 30+ mile gateways as well, so that's an added variable. Anyway, thanks for showing the public how this works, and hopefully more hams can have this in their toolbox.

[@TheTechPrepper]

I love it when you stop by the comments, Denis. Hopefully, the video was not too high-level for you. I was really trying to figure out how to explain this topic to all the new non-hams (or newly licensed hams) that are joining the channel. Live demos are tricky especially on 5 watts at this distance. In the end, I hope that it is enough to get people going with APRS.

[@NickFrom1228]

Nice vid. No need to apologize. We are all at some place in all this and you have been clear about what you are doing. If anyone complains, they are clearly not paying attention.

[@TheTechPrepper]

Excellent point. I appreciate the kind words. More content coming. Have wonderful weekend.

[@blankreganon5395]

These videos are great. Since you are new to all of this, you are relaying knowledge that you are just learning yourself. Because of this, you are including all of the pitfalls and how to get around them. And, your "failures" keep it real and help us to see what to do it it doesn't work correctly the first time.

[@TheTechPrepper]

Thanks. When I started this journey a little over two years ago I felt that the context of being a newbie might help others along the way. It looks like sharing the experience and growth along the way is helping a few people. Cheers and thanks for your continued support.

EDC multi tool is silly, until you need it. Loved it! Enjoying the No Random Contacts series and this video. Thanks

[@TheTechPrepper]

I thought it was silly until I moved to the desert. Like many, I thought a pocket knife will do...it will not. Also, plastic hair combs don't work for big Chollas. Somone recommended it as a tool to remove them, but it failed for me if you have one with upwards of a dozen attachment points to your skin. Take care.

Good call to send text where you got all the thorns. You will rarely get injured while in the perfect place to send a message. Getting a cactus is a good example of a random spot simulating a worse injury.

[@TheTechPrepper]

You're exactly right. It seemed like the logical point to stop and a raise the message. It was not the greatest position to get the signal out, but accidents can happen anywhere.

Never think you have to know everything to give input on something. I've learned a lot from your videos, things I never knew or expected with analog radio. I'm still studying for my ham tech, so I'm very new myself, but packet radio greatly interests me. I'm in the computer networking world for a living and it's crazy how much it ties in with what I know for a profession (after all, networking is essentially just data being carried over different mediums, analog radio is exactly that). Love your videos, they have been my main source of information that makes me excited to get into the radio world. Why stop at voice? There's so much more out there.

[@Quoodle1]

Additional suggestion: Try carrying a small yagi/uda beam antenna. I'm an Emergency leader in California in a place with lots of hills and mountains and canyons blocking people. While we do have a lot of repeaters and our group uses some crossband repeaters (even linking two together), there is one person in our group who communicates a long distance by "bouncing" a signal off a nearby mountain. Haven't tested the extent of the capability, but it does work for him.

No more Whizbang Series 97.A digital or Hoohah 49 Integrated SignalSeeker. I’m in the Bighorn Basin of Wyoming, surrounded on all sides by mountains of dizzying heights (DN54d?). I don’t do DX. My son is 150 miles crow-flight, the other side of Powder River Pass. NVIS 80 meter does it for us. When the balloon goes up, I think my FLIR LS-XR and Garands will be more valuable to me than the ability to send email. I could be wrong… so we’ll see.

[@TheTechPrepper]

I like your style. When all is fails, sideband voice and wire antenna to the rescue. I've been doing a bit of 75m and 40m NVIS these days. That's the way to go.

[@singletona082]

While I lack the funds to indulge. This is something interesting and potentially worthwhile. Especially given how most would scoff at radio because 'cellphones are everywhere.'

[@TheTechPrepper]

I refuse to be that guy that says, "I told you so" when the cell network is impacted for more than a day. You can always get into radio with a $25 Baofeng radio from Amazon. That's what I ran the first year. Take care.

[@jasonhopkins3309]

Thanks for the videos! I'm new and you explain it in an understandable way. Getting current info on packet radio is difficult. There seems to be a lot to learn at the same time. It's hard when you're not sure if the info you're reading from 20 years ago has been updated or not. Thanks for examples of things that work. I agree, it would be good to revamp this to make it more streamlined. Too bad the radios don't seem to have emcomm as a priority. From what I can tell, the discontinued Kenwoods were the best. I think there is an obvious market for an HT with a built in TNC. But, maybe I'm wrong or don't understand what I'm talking about ;)

[@TheTechPrepper]

Glad to hear that you enjoy the videos. I try to make it simple as I really struggled to get into amateur radio and nearly gave up.

@0:48 Youch! Might be time to invest in a pair of trail hikers. When I was still trail running, had to use those along with track pants for some of stinging nettle patches around here. Just to give some input, when I signed up for the SMSGTE service, it required a phone number sent through APRS. To ensure my actual number was not publicly known on the APRS network, I went ahead and downloaded a second number app, and used it once to set up the SMSGTE account. Logged in, set up aliases, and uninstalled app. Also, neat device at the end of the video. Looks like I'll have to buy one.

[@TheTechPrepper]

I have been looking at running gaiters for awhile, but they all seem better suited for keeping dirt out of the show. Thanks for sharing your tips. Be careful with the approach of using a second number app. If you ever forget your password, it will try to use that original number. The nice thing about using your actual phone number is that I believe you get some additional administrative management functions. At any rate, its great that you went through the registration process and were thinking out of the box. I signed up over two years ago and have completely forgot the details of the actual registration process.

[@natehowe7975]

Appreciate all your videos, thanks for taking the time. Do you foresee getting a satellite communicator such as a Garmin inReach series to push messages back to your wife? Or perhaps one for each of you? I hate the subscription fees but if it would guarantee another option I would consider it for my household. I’m just afraid that it still depends on Internet and servers that might be down - my question is whether two of these devices route through the satellite infrastructure or rely upon ground technology to finish the connection. Meanwhile, VX-6R is awesome with its wide receive and durability. Do you foresee getting an FT-5DR with APRS built in? Probably not as durable.

[@TheTechPrepper]

You are very welcome. Yes, to both. I plan to get the lowest tier plan for a Garmin InReach. I also plan to get a FT5DR specifically for the IP67 rating and built-in APRS. They're on the board for 2023.

[@natehowe7975]

I was looking at the inReach Mini 2 but they just came out with the Messenger. It has more battery time and can recharge your cell phone, plus it is cheaper. It seems the Mini 2 is more about the GPS features, so that might be the one you prefer. I was thinking to get the annual subscription at the lower monthly cost since you never know when you might need it. I wouldn’t use it much, just keep it with me in my EDC backpack. As for the FT-5DR, I think it has less transmit frequencies. Not sure if MARS/CAP would address that. The VX-6R has tons of transmit frequencies that add to its emergency prepper value. But for anything digital the FT-5DR would be the winner. The price is a bitter pill, but if you recommend it I suspect sales will go up!

[@blankreganon5395]

I don't have a Garmin but it sounds like it doesn't give you a permanent phone number. It is great to send messages first to a cell phone and they can reply. However, the person with the cell phone can't text first. One way to get around this is to send a test message from the Garmin first. Not sure if this is still true, but something to check before you buy one.

[@TheTechPrepper]

@@natehowe7975 Nate, I am personally looking into research and getting a Garmin InReach. We literally made it home at 0400 this morning after having a medical emergency on Mt. Whitney. Our family member is recovering now after a lengthy rescue.The Garmin InReach Mini saved the life of a family member. There will be a video coming in few days. Radio actually failed.

[@dangermandave67]

Sucks that the Mobilinkd TNC isn't available. I've used a Baofeng in VOX mode with the Btech cable going into a USB dongle connected to my Samsung phone running APRSdroid. It works OK most of the time, requiring some fiddling with media volume and VOX settings. Finished up buying a FT-2DR, which works better. Most of the time, I've managed to hit a repeater just using a Signalstick or telescoping whip antenna. Occasionally, I've needed to throw up a roll-up j-pole. Amazing how far away you can hit a digipeater from with just a HT, provided you are are at a sufficient elevation. My main application has been putting up SOTA spots and sometimes sending an SMS to my wife. Question for you: is HF APRS still a thing? Are folks still using 30m with Direwolf to send packets? Or has everyone migrated to JS8Call now?

[@TheTechPrepper]

Actually, I originally bought the Mobilinkd TNC2 for spotting myself for SOTA. It worked incredibly well in my area. Yes, APRS HF is still a thing, but I have yet to try it. It seems that JS8Call and FT8 are the new cool kids in town. My group and I actually favor NBEMS (fldigi+flmsg using the 8PSK-1000F or MT63-2KL modems) on 2m/440 FM. These modes do not work with the Mobilinkd since that's a packet-only device, but the DigiRig Mobile works great here.

[@Henviggdbgjt]

Can you set up a more powerful mobile unit with good antenna in your vehicle to digipeat your message to the internet gateway?

[@TheTechPrepper]

Yes. I run a 50 watt Kenwood D710GA in the Jeep with built-in APRS. It has support for digipeating. I have a Diamond K400 mount with a Comet SBB-5 2m/70cm antenna. It's a great solution to the problem you are describing. There are other mobile radios that may do this, but I only have experience with the D710.

[@michaelchambers7691]

Try a Diamond RH77B or RH77CA whip antenna, it may improve your range.

Wonder if that abbree 42.5" with some tent poles, retractable fishing pole, something to get antenna up higher would change things?

[@dojohns]

Thanks keep it up. Ignore the “experts” 😊

[@TheTechPrepper]

Thank you, I will. Take care, Doug.

[@imagingconcepts]

Good work, and don’t sweat that you might not be technically precise, it’s called Amateur Radio, not I am a “Self Proclaimed Expert Radio”

[@TheTechPrepper]

Haha. Excellent point. Thanks!

[@boonedog1457]

Put some survival trousers on bro! Ouch!

[@TheTechPrepper]

Trust me...I've looked into leather running gaiters, but still have not found anything. Thanks, man.

[@boonedog1457]

I know you are dealing with intense desert heat, so I get the shorts. They make a survival trousers that is also snake proof, which would prevent the torture you go through. I've spent a lot of time in the desert and I do get it enough to understand the harsh environment. Great videos by the way! Many thanks!

[@michaelchambers7691]

I have a working RadioShack HTX-245 dual-band HT that uses only 3 AA batteries and I have adapters to convert to using AAA's.

[@TheTechPrepper]

That's a classic! I have a soft spot for older radios that still perform well. Thanks for sharing!

[@vestale4]

Great video, by doing, testing, filming and puting on KZbin we all learn! Try to send your positon at the begining, if there is a digipeater(like W7MOT-3) nearby, you will receive it back, and you will know that 2 way comunication is working using APRS. After that, try to send the message and expect ACK. #mapme function/command from SMSGTE is also a nice feature. Shoutout to Paul, VE3OTB, the creator of SMSGTE service!

[@TheTechPrepper]

That's an great tip. Thanks! A big thanks to Paul for providing this service.

[@drewrinella1646]

Hey I got your plans on your blog to work with a Pi 2 and the wifi dongle you linked on there. The code just stays as WLAN0. Thanks for doing that.

[@captainhindsight2215]

Have you looked into the VR-N7500? It looks promising with the right software. If you could make it work with Emcom Tools that would be the ultimate in inexpensive off grid comms.

[@TheTechPrepper]

That's a very interesting radio. I appreciate you putting it on my radar. I'll have to look into this. EmComm Tools is very much delayed due to time constraints, but I am changing things up so that I can start work on it again.

[@captainhindsight2215]

@@TheTechPrepper I appreciate you taking the time to do things right. As you are well aware far too often both hardware and software are released half baked. I trust that when it's ready, it will be ready.

[@TheTechPrepper]

@@captainhindsight2215 Thanks. My plan is just to do an annual release, so I want it stable. In fact, you should be able to use the original version out the gate forever if I do my job right. The plan is release a new version once a year with all the related software upgraded and tested together. I also plan to update the datasets once a year. A lot of this has to do with the fact that is meant to be an offline-first, emergency communications platform. Every new feature add the potential for bugs. The Internet will never be required to use this platform, but it will be supported if the user wants to update various data sets (i.e. call sign database, map tiles, repeater locations, etc.).

[@feltusfeicit]

Worth noting that SMSGTE does not work with all radios (sorry if this has already been mentioned). I was disappointed to find that it does not work with AnyTone HTs natively, it probably does if you use the TNC and a data cable.

[@Trent28888]

I made a wearble antenna that would of been good for doin that but also have u ever thought about makin a portable yagi u can take with ya?

[@LarsLarsen77]

Some asshole started spewing APRS packets on our local repeater today. Thanks for that.

[@dougdaniels]

What current production HTs (Kenwood/Yaesu/Icom) that have APRS capability built in would you recommend? I have an Android tablet but no TNC, and as you said, the fewer components, the fewer failure points.

[@TheTechPrepper]

Take a look at the Yaesu FT5DR. There are others, but I'd have to research them. I also understand that the latest model of the AnyTone 878 also support APRS fully, the early versions only beaconed.

[@pale_2111]

Icom doesn't make a radio with APRS. They have DPRS, which is a digital version but nowhere near the capability of APRS. It (DPRS) only shows your GPS position to another station while talking on D-STAR Reflectors, over a D-STAR repeater or on simplex in DV mode. As an Icom fan boy myself, I wish they would make an APRS radio or make some improvements to DPRS. Kenwood discontinued the D74 HT and D710G mobile radio last year. You can still find them used, but people are going to ask a ridiculous price for them. Not sure if they have anything planned to replace those radios in the near future. Yaesu made the FT3D and its replacement, the FT5D. Both have APRS capability built in. A used FT3D can be found for around $350. I believe they use the same battery, don't quote me on that. A brand new FT5D is around $500. I've got the FT3D and love the radio. It's easy to use with the touch screen and fairly easy to program. The downside is the battery. The largest battery is 2200 mAh, which doesn't last too long with the GPS turned on while using it. It does have aftermarket batteries made by Batteries of America. Just wish Yaesu would put a wee bit more thought into designing a radio. Other than that, the FT3D is my "field" go to radio. I take it while hunting here in Tennessee just in case I get into an area with no cellphone service and need some help. I don't have any experience with any DMR Radios that have the APRS capability, so I can't comment on those. Hopefully this helps you out if you plan on buying an HT with APRS capability.

[@dmitriyshvidchenko6657]

@@pale_2111 For TNC part look at DIGIRIG - I have not tried it with APRS on Android yet, but it works really fine with Winlink. The only inconvenience with it - it doesn't have bluetooth, so it requires two cables 1 between HT and DIGIRIG and 2 between DIGIRIG and the phone.

[@TheTechPrepper]

@@pale_2111 It's a shame that Icom does not make an APRS radio and that the classic APRS radios from Kenwood are now discontinued. I have two D710GA's and previously owned a D74A. I sold the D74A as I would have broken in it the backcountry in short order, but I did love the features. The SSB receive capabilities were great, too. These days, it seems that the only game in town are the FT5D and the new AnyTone 878. Cheers and apologies for the delay in response.

[@Dave_KE5ES]

Question: Is there a list of current APRS capable handheld radios? I already have a couple but they are rare and out of production (Kenwood 74 and 72). I was thinking of a cheat sheet laminated with all the different APRS codes for smsgte, email, sota and pota spotting.

[@TheTechPrepper]

I have not searched for a list, but the Yaesu FT5DR and newest model of the AnyTone 878 supports it. I created laminated cheatsheets for APRS 2 years back, so that I can remember the format. I'll try to show then in the next video if I don't forget. I'm on a mountain at the moment. My cards cover: SMSGTE, EMAIL-2, WXBOT and APRS2SOTA.

[@tomsmall6220]

What about using an audio cable between the phone and radio, instead of the Mobilink?

[@TheTechPrepper]

That works with some radios. The Baofeng UV-5R can do this with VOX and just a cable.

[@4acae86]

lol. I’ll bet a lot of these people complaining used to play with the phone system connected to the repeaters 30 years ago. I remember my dad and uncle using what they called an autopatch in a similar way to connect to the phone lines. This is a very similar thing, just with integrated packet.

[@TheTechPrepper]

Autopatch is great. We still have it in our area. I did a demo it here on KZbin about 4 years back. Search autopatch on my channel page if you're interested

[@MrLilmac75]

Their website says they are shut down, but I did not confirm it.

[@ManuelPinner]

I have a Yeasu FT5D HT!

[@TheTechPrepper]

That's a beautiful rig. Lucky! An all-in-one APRS radios like the FT5D is the way to go.

[@garylawrence1575]

Now that SMSGATE is not working or is for the time being you ought to explore putting messaging directly to WhatsApp in your emcomm software

[@TheTechPrepper]

There are no plans to include any software packages that require the Internet to work.

Boots and shorts my boy.

Did they make chaps or something to protect those ankles. Hate to trip and fall into those “cactus” bushes

[@TheTechPrepper]

There are running gaiters, but these cholla go right through them. Leather would work, but then you run into a comfort issue.

[@stevenpeterson8444]

so, if APRS isn’t guaranteed in the backcountry and you’d have to carry a satellite device for emergencies anyway, why not just leave the APRS at home? especially on a backpacking trip where weight matters a lot.
