Hi there,
I have just built a DTMF tone controlled relay and have it functioning well when taking audio feed from the speaker output of a WOXUN UVD1P.
But I am struggling to get it to take input from a tait orca. So far I have tried feeding it from the headphone socket of a speaker mic and also from a clip on 3.5mm audio socket adapter but with no luck.
The manuals I have looked in say it needs an external speaker with an impedance of 32 ohms.
I only have an 8ohm speaker available, which again works fine with the woxun and I have an 8 ohm audio transformer built into the circuit to provide isolation (which could be part of the problem).
Any ideas or suggestions of how to get the audio feed from a tait orca driving my circuit?.
Cheers,
Draco
