[chirp_users] Baofeng UV5R dtmf on receive
i have need to use this radio as an alert pager for local vol. fire dept. see where to enable dtmf on transmit, but no capability to do so on receive. is this possible, and/or am i missing something in the programming. basically need to receive only one tone. thanks for help. jim kf8sj
Not implemented on the radio firmware. I have an Arduino sketch that may help, I'll send it tomorrow

thanks. would appreciate any help possible. with the advent of narrow banding, all our pagers will not work. we are paged out by the sheriffs department over a public government channel using the dtmf codes. have already explored their sending either a different pl tone, or a dcs signal, but their system is not capable of doing either. for the price of a handfull of pagers, could equip the entire department with these units, and gain a talk around radio.
not sure what an Arduino sketch is

HI Jim
I see where you are saying dtmf, but I wonder if you are talking of CCTCS on both TX and RX. On ham rigs you can have a tone squelch for receive and one on TX also a choice, on RX it is used so the receiver only receives the desired repeater, on TX so you only get into the desired repeater in highly dense repeaters. But my bet it could be used as a security measure. When it is used for both it usually is called Tone Squelch or shortened to TSQL I have that on my VX5R for some repeaters which tells the rig to look for the tone on receive and open the rx and to tx the tone so the desired rx opens to receive the signal. This may not be what you are talking about but you mentioned not seeing it on the layout for the rig you are using but is there a field for TSQL?

Most Fire Stations and ambulances require DTMF Tones to tell them which station is being sent out to where. The Baofeng does not have this capability to receive them and activate the squelch to open up when the tone is received. Sorry but sounds like you need a more professional radio.

Well, not exactly. The system here is "two-tone" which has one single tone transmitted for a couple of seconds and then another single tone for a couple of seconds. Precise timing I can look up on Tuesday if needed. Google "two tone paging" for some of the angles. http://www.batlabs.com/qcii.html has some of the info although it doesn't cover what we use, nor several other variants.
One of the tone plans out there is called "Plectron"; it's used in the next county to the north. In this county we use the Motorola tone plan. Here's a sample: The first column is Motorola's "hex code" (why they call it that I don't know but that's what we put into the dispatch console to specify the tone pairs), and the other are the two tones sent in sequence. (Missing initial columns are the various people's names and call signs.) One annoying thing about Motorola's approach is that they include frequencies below 300 Hz and I have removed them whenever possible. Icom and Kenwood radios can be set up to double as pagers but they don't work well with 296.5 and basically don't work with 288.5

DTMF is another whole thing. It's one of many possibilities for ARES paging that we need to figure out.
HTH ;B
Bear is correct. Before we went digital in York County, PA, we used Motorola and Plectron monitors. The Dual paging tones are not the same as DTMF, which is Dual Tone Multi Frequency (used on telephones). Unfortunately, the UV5R doesn't have that capability.

We used to use that here in the late 1980s. I was toying with the idea of building a decoder (before software methods were practical) when we had the system installed. I got good at picking the tones by ear in the end, could tell ours from others in use. Those days are long gone, as we now use a statewide single frequency POCSAG network, independent of the voice channels for emergency callouts.
Two tone voice pagers are still the defacto standard for volunteer fire departments in this part of the world, so it isn't so obsolete. Some areas each department has their own radio frequency, and tones for the pagers may or may not overlap, other areas use a shared frequency for the county, with different departments having different tone pairs. The county to the North of me, when they do their weekly test, sends tones for almost 2 minutes before the dispatcher can put out the announcement. (4 seconds per pair, 50 something paging groups)

Pretty gross procedure. Stacking just four tone pairs is a lot. Three pairs would take twelve seconds which is approximately the impatience timeout in the human brain.
;B
what i need is dtmf aka touch tone. this is in the audible range ancd the uv5r will generate it for control purposes. it is momentary aka touch tone. the system you are describing is a continous tone in the 100 hz range and is filtered out of the receive audio.
thanks for reply

ok. thanks for lead. checked it out. seems to come in around $110.00, which is a little more than slightly. uv5r plus is out there for $49.50 canot find anywhere including factory site where this unit is approved for fcc part 20 operation. appears to be ham only unit. capable of out of band operation. we are trying to stay legal. the uv5r is listed for part 20 useage.
looks like it has the tone capability i need. and everything else looks good. but need the part 90!

It's a program to run on an Arduino microcontroller board. The code I have uses a Goertzel algorithm to detect tones. It can do dtmf or monotone signals like the tone paging (plectron?). When a tone is detected it can throw a relay.

thanks. would appreciate any help possible. with the advent of narrow banding, all our pagers will not work. we are paged out by the sheriffs department over a public government channel using the dtmf codes. have already explored their sending either a different pl tone, or a dcs signal, but their system is not capable of doing either. for the price of a handfull of pagers, could equip the entire department with these units, and gain a talk around radio.
not sure what an Arduino sketch is

Not implemented on the radio firmware. I have an Arduino sketch that may help, I'll send it tomorrow Tom Morris, KG4CYX Mad Scientist, Miami Children's Museum This message sent from a mobile device. Silly typos provided free of charge. On May 25, 2013 8:36 PM, KF8SJ@aol.com wrote:

sounds like this needs an additional board. have not been inside the box, but expect that from size, ther is little extra room. external is not going to work in this case.
thanks for reply

It's a program to run on an Arduino microcontroller board. The code I have uses a Goertzel algorithm to detect tones. It can do dtmf or monotone signals like the tone paging (plectron?). When a tone is detected it can throw a relay. Tom Morris, KG4CYX Mad Scientist, Miami Children's Museum This message sent from a mobile device. Silly typos provided free of charge.
