| You can purchase DTMF encoders, completely assembled, as accessories to be added to older amateur radios. These are still available as far as I can tell and the cost is reasonable ($20 US maybe). That's not quite what you wanted but it could be an alternative for you.

| A thought - if you know someone who is a radio amateur you might record a transmission via a scanner. VHF and UHF handhelds and mobile radios almost all have DTMF keypads on the microphone. Again, not what you asked for but an idea.

| Here is DTMF tones in .wav file. The sequence is 16 tones one after the other, 2 seconds tone, 0.5 seconds no tone order is 1234567890*#ABCD Fidelity is not perfect, a bit of distortion, but should be useable.
