need the schematics of how you connected it to the link or to the ptt i need a 1750hz tone to open the reapetor so any schematices woulld help..... great vido
I'm leaning toward an mp3 player with a different hour long mp3 for every tone. (I need four different tones around here.) I ordered my $1 player from China, should arrive in a few weeks! Audacity is free software that can be used to create the Mp3s. In the meantime, I'm looking at an old smartphone with a tone generating app. On my ICOM IC 255A, the signal gets injected by soldering to the wiper lug of the "Dev" pot.
Would it not be prudent to put in a decoupling capacitor along with at least a mild low pass filter? pwm got some sharp harmonic edges. but I guess if it works.....
When you say, "I'll just plug in the tone board", Just what are you plugging it into? Just coincidentally, the tone I need is also 107.2. Looking at tone boards commercially made, this beats them to hell with a stick for price. I can get the 5 Volts out of the radio. And I know where to connect it. I just would like to see a schematic, with parts labelled. This is a really cool project.
@@doombringer1505 Hi US,CTCSS tones encoder are generally fed on the top side of the fm deviation pot adjustement inside your radio.They should not be fed from the microphone socket.Generally I set them for 750Hz (CTCSS)deviation+4.2khz (voice)=4.95khz max FM deviation on wide bandbandwidth,or 375Hz (CTCSS) deviation+2.10khz (voice)=2.48Khz dev max on narrow bandwidth FM systems,do a google for PIC based CTCSS ull find them.

Don’t you need to filter the square wave output of the arduino so you don’t generate harmonics all over the place?

Nice

John Cundiss Yes, that would likely be a good improvement.
Still no github? Or sketch for arduino
Can I get a schematic of what you did. Need to do the same but on 91.5 if you could help. Thanks
No link to any github either.
Great tease. No schematics whatsoever. The "reference" gives no real info into THIS application.
sorry, not a tease, I just never got back to it. Since there is interest I'll see what I can do, and properly decouple it.
