Many thanks for showing how it works. I once worked in emergency communication between hospitals. Sending reliable text is important in those situations. At first I wondered about why transmissions start with static. Then I realized it was to trigger the VOX at one end and the squelch at the other.
I tried this and it always displayed your callsign, with most messages saying "decoding failed". Except UA-cam test 2, that one got decoded. I was watching on an Amazon echo show 8.
What would be really cool is if this app could grab your location from another app like Gaia a gps/ trails mapping app that off road enthusiasts use to plan trips through the great outdoors and contains maps of trails, state and federal parks and automatically transmit the data for the receiver to manually or better yet somehow load the data back to another phone running Gaia or similar app. It's the next evolution of this project. Partnering with the folks that developed Gaia would benefit both especially on search and rescue operations.
you realize any radio with GPS already does this? you can get ones as cheap as $40 like an abbree AR-869 up to $300 like the anytone 878. DMR radios almost always do this along with private calling, texting to other radios, texting to phones, and high level encryption. btech even has a GMRS radio that can do this called the GMRS pro.

Amazing!!! I wanted something like this and I was looking for an app or software to do this about a month ago with no success. Thank you so much for sharing this 👍
ModernHam, you might enjoy SSTV. It works the same way - app on your phone and acoustically coupled. You can use a repeater for increased range, since anything that will go through the passband of the radio will also go through the repeater. (of course get the owner's permission). SSTV can be used at a disaster/accident scene to get pictures back to the EOC when you have no cell service. Btw, it's good to see young guys experimenting. Most people today either get their ticket and never use it or maybe just check into the local net once a week. They are missing so much and don't even realize it.
This is an extremely interesting topic. The information was very concise. The demonstration was very straight forward and simple. Also, you have a beautiful girlfriend, wife, or friend. Everything works! The best part was, budget minded equipment was used instead of some $490 Yaesu handheld transceiver that produces less power, has less battery life, and it is terrifying if you drop it. If you drop the budget minded radio, there is little worry. It will likely survive, just like the Yaesu. But if it does break, just buy another one and use the broken one for a project. If you drop the Yaesu and it breaks, the sky darkens, lightning streaks across the sky, and the horsemen of the apocalypse come riding down. Woe to those that break a Yeasu!
This is amazing and just the tech I was looking for, the ability to send voice on vhf and then data (mainly GPS) without needing to deal with cables to another handset for SAR activity. Would need option when you press on a msg to be able to copy to clipboard.
Very good idea. It would be useful to develop encryption support. This could be a simple password that both sides know, or encryption with an asymmetric key and with a "phone book" (call sign - public key).

Thank you for sharing. What modulation does this use? APRS is AX25 packet, basically FSK. I did not understand the cable statement on APRS since you can buy an APRS radio.
The weak link in APRS is the underlying packet does not include Forward error correction. If a packet doesn’t match it’s CRC 32 error check the packet is rejected. I’m curious if this mode will allow digipeating. Or if we can use a Bluetoothaudio connector on the speaker mic plug.
@@AlphaFan90 Although APRS uses the UI datagrams, it names all digipeaters in the system as the same name with a number on the end representing the number of hops the packet is permitted to propogate outward. aprs digipeaters also store the CRC checksum of any packet it has digipeated in the past 30-60 seconds to packets don't just ping pong back and forth between two nearby didpeaters until the hop count it used up.
Using vox without a cable is okay in a no war zone. However I suggest if you are in a war zone best transfer audio with cables or Bluetooth. Need to keep things quiet if you got military prowlers looking for a 🎯 target. War is gaining momentum around the 🌎 sad to say. Good channel great radio fun.
@@ModernHam How does this handle typical system notifications on a cellphone though? If you're using VOX, those will get transmitted if you're just using a simple cable to connect your phone to your radio.
No, it automatically starts to delete messages after it reaches a certain number (which I don't remember). Remember, this app is designed for emergency communications operations where there needs to be a "paper trail". It is specifically designed that way so you can not accidently delete messages.
I would think as long as you don't use a repeater's frequencies or a commonly used frequency like the APRS frequencies you'd be ok. It is always annoying to hear digital modes on analog repeater frequencies. VHF and UHF do not have a digital portion of the band like the HF bands do. It would be nice if they did.

Which frequency to use on radio?
When u tx from app - do we have to press PTT on radio ?

Would this work if i wanted to use a kway cable plugged into the phones 3.5mm socket? Also if dcs is programmed on the channel will it still work?
I take it that this line of site communications. Like using packet radio unless you use a digipeater.
Yeah more than likely.

@@AlphaFan90 I assume it could also be used with a simplex repeater as well since it's just audio.
@@fortwoods yes. Works over a simplex repeater. There is a parrot mode in the app doing just that.
The Rattlegram app would be great if it didn't have the huge drawback, which is that it doesn't work with the lock screen.

I'm in a metro area if 3 million people. I hear maybe 3-4 people a month using ham radio for speech. Now we're supposed to do texts too.
