Transmission Completion Confirmation Tone

Here is the start of my next project.

A Custom Transmission Completion Confirmation Tone A.k.A. Roger Beep

Here is the circuit board, salvaged from a goodwill bargain wireless doorbell system

I am going to be powering the device from the Transceiver using a 7805 regulator and a voltage divider as the device ran off 4.5 v via x3 C batteries.

It is pre-programmed with a short tone and a double doorbell style sound wich I have tweaked the resistance...
