Baofeng Radio PTT-ID Feature Demo

Demonstration of the PTT-ID feature in Baofeng radios. I go through using BOT (beginning of transmission, or prefix) IDs, EOT (end of transmission, or appended) IDs, and the combination setting of BOTH. Also, this clarifies how the DTMF-ST setting affects the operation of the keypad dial tones and PTT-ID.

[@ElitesEngineering]

At first I was like why does your calculator have a radio function... lol

[@Coalrollinfurry]

thank you, this will be a great tool for my repeater explorations and building a repeater station and none of the baofang manuals, witch are suprisingly well written explain much about this feature aside from what it can be used for and how it originated for radio use

[@rafdavfl]

For commercial communications it would be ok. But for an amateur radio station, it does not transmit the call sign.

[@guillermogil3391]

This is amazing, you covered everything, with a complete explanation and a perfect demonstration. Great job!

[@Manumave]

Every radio should have PTT-ID functions

[@KandiKlover]

This is great, my UV-5R+ does it, I keep my repeater locked and opened by the dtmf. Took a while to figure out how to change the radios id haha

[@tieline1333]

Just what I needed! So now once I release PTT the Audio in the RX Direction can be tripped using a relay and I can have automatic single-direction audio :)

[@redcartiers]

I actually accidentally turned this in and when I heard it I thought it was calling 911 or something I was like "oh gosh oh fuck what did I just transmit" cause it sounds exactly like a phone keypad tone

[@DazzleCamo]

It IS a phone keypad tone, that's where DTMF originated. Its copyrighted term is "touch tone" by AT&T (1963)

[@wimpog97]

Fantastic explanation!

[@ImprEcr]

Very Educational Video.. many thanks for clearing that up ;-)

[@TawniiDareeT]

well done.. you did not miss anything.. everything i needed i found it under this video... Thanks allot for all your effort.

[@EmperorMingg]

I just need to say that, you’re the first person I’ve come across in the western world, that correctly pronounced BaoFeng. All I hear is bayofehng.

[@RoyalKingTrucking]

i'm a new ham op what are these for anyway?

[@JohnThornley]

Very clearl explanation. Thank you.

[@oberwerewolf]

Hello. Have you anu idea about indication of DTMF code on the display? When i send signal code from one baofeng radio to another, i can hear the code in speaker of recieved station, but DTMF code not indicated on display

[@wisteela]

It can't be displayed.

[@solar_ize]

Great video, but you jumping lots of steps here. Can you explain what this whole thing about DTMF, ANI ID, S-Code, etc all mean?

[@gmctech]

great video... I've never really played with these functions buuuuuuut now I will be as I'm setting up relay Banks with an Arduino board and a dtmf controller. I just hope the dtmf controller and Arduino board can pick up the quick dtmf tone burst.

[@Rareed63]

I wish they made a radio where you could program your CW-ID

[@jameshoffman3730]

4thebadwolf , how do you do that?

[@erikswanenberg8719]

very nice and clear video. Pleasant to watch. You have more demonstrations?

[@x86_architecture10]

Lol, it makes it sound similar to a police radio when you key the mic.

[@djace8956]

can you have the tones on both like thro the radio speakers and the scaner? and what tones do they have

[@the1spyderryder]

That means nothing for official ID. The only ID that counts is CW or Voice

[@wisteela]

Excellent video. I have the same model of Baofeng. What scanner is that?

[@mickgatz214]

Great video Matt, but like me n helping pll with computers I go wayyyy too fast!!! lol No problem budddy, I guess i will just have to watch ya video over and over again to get what you are trying to say/teach. Much Thanx Anyway! (from Australia) Mick

[@josephbarron6899]

Can you explain what the purpose of these tones are for and what systems use them?

[@mattbjrs]

These don't have much use in the amateur radio world. However, in the public safety world, they serve to trace the radio back to a specific user. The radio is assigned a unique ID which is programmed into the radio and then recorded in a lookup table. When the user assigned to that radio keys up the mic, the ID is transmitted as demonstrated in this video. This could show a radio dispatcher who uses computer aided dispatch (CAD) the identity of the person who keyed up. This has several uses such as when the person calling on the radio forgets to identify themselves, the person is in distress and does not have time to identify themselves, or the dispatcher was busy handling radio traffic on another channel and missed the last person calling on the radio. The dispatcher would just have to look at the identity on their screen and then can call back to the user. Another use would be to save the radio traffic in an audio recording and being able to go back through the historical data and identify who transmitted which message. This could be used if some kind of incident occurs and the timeline of who said what when needs to be pieced together. Most public safety organizations in the US do not use DTMF encoded IDs. The majority use MDC1200 which sounds like a crash of static sound at the end (or beginning) of the transmission.

[@josephbarron6899]

@@mattbjrs thank you very much!!!!

[@davepickering997]

Would be nice to see this programmed in CHIRP. I was searching for how to do this teaching and setting up professional system but unfortunately its too basic. Back to my Motorolas

[@BobJoe64862]

It can be programmed in Chirp. Select the Channel you want and click "properties" at the top of the screen.

[@YllwFvrPB]

perhaps someone familiar with baofeng radios can help me. police radios make a static sound, like a brief hiss, at the end of a transmission, rather than those painful Roger beeps. can something like that be set up for a baofeng?

[@marcot3333]

+DOTLeo62 no. What you're hearing is likely MDC-1200 signaling and it requires a real radio. Baofengs are nice for what they are, and worlds better than those junk FRS "22 mile" radios but aren't anything close to a professional communication device.

[@YllwFvrPB]

+Marco T I had to Google that, but thank you very much. I used them for years, but that doesn't mean I understood anything about them. that's some interesting stuff. a bit behind me atm, but I'm learning.

[@hey_buddy_waz_up]

What an easy way to annoy and alienate any other people on the repeater.

[@thomasrogen3739]

Did I miss the displayed, displayed alphanumeric displayed on the screen of the scanner or just all the beep beep bops?

[@mattbjrs]

It's just the beeps/tones. The scanner is not able to decode them.

[@raso456]

Thank you.

[@Malabus73]

New to this. Why would you need to do this.

[@Wizardof]

Dumb queston but WHY is the CTCSS changing each time you use the BaoFeng? Why does it show up differently on the Pro106 scanner?

[@mattbjrs]

I think it's due to random interference in the signal that happens to be around the lower frequencies that CTCSS uses. Since CTCSS uses a continuous tone signal as its squelch code, it's susceptible to interference. In this case, a random signal that produces waves close to 67 Hz for a short period of time will look like a 67 Hz CTCSS squelch tone even though I don't have a squelch tone programmed into the Baofeng. Since the Pro106 scanner supports digital radio, if you don't put it in CTCSS squelch search, it will take a second to begin receiving an analog signal because it has to determine that it's not digital first. Setting it to CTCSS squelch search mode is a way to tell the radio that the signal is definitely analog and eliminates the delay. Newer digital scanners allow you to specify whether the channel is analog or digital without this hack. Since it's on search mode and I'm not using CTCSS, it will display random frequencies based on the interference.

[@Wizardof]

@@mattbjrs Thanks. I have the same scanner 😛 I figured the BaoFeng would have the same CTCSS all the time but ok. I wish they picked up Phase II. Oh I hope you have the Win500 folder saved because the site is OUT.

[@EthansMCLPs]

Do you guys know how cops sometimes have a tone in the beginning and end of transmission, is there a way to do this with a baofeng?

[@wisteela]

No, they can't do that, only DTMF and roger beep.

[@snowcatxx7117]

Can you change the tone ?

[@Roshan_420]

Tone represents the number

[@karlmadsen3179]

All those beeps are so annoying. Maybe just a simple "roger" beep?

[@carlos.coronado2760]

tengo el ptt bloqueado como le ago para desbloquearlo porf diganme

[@djace8956]

can you go tho the s codes?

[@PurcellAdam]

Why is this desired?

[@mattbjrs]

This is a feature mostly used in commercial radio systems to record which radio is transmitting a message for auditing purposes later such as an after action review in public safety. It could have some uses in amateur radio if you decode the digits and have the radio receivers process them in some way such as a repeater recognizing a certain user is transmitting on it or using the beginning s code to automatically set up repeater linking. As others have pointed out though, in the amateur radio service, this does not satisfy the identity requirements and you still have to transmit your call sign per FCC regulations, so the ANI is probably not that useful to hams.

[@PurcellAdam]

​@@mattbjrs I got into Baofengs because of Airsoft (like Paintball), and have had a blast learning about this stuff. I especially like the audible sound options that can simply mean the person is done talking, though shorter codes would be good, and helpful hearing a tone associated with a voice. I also know there's a trick to making one or two Baofengs into repeaters. I also do production professionally, including drone work. I'm interested to see if the repeater/identifier thing could help isolate particular people so they can be given their own audio recorder input on my Zoom 6 track recorder. Can repeaters be used to extend range? Going off of old memory, and not that experienced, I remember that being something our organization discussed for big games.

[@Iowarail]

Bowel Fung, funny.

[@Elfnetdesigns]

Utterly useless if its not a true PTT ID system like MDC1200..
