That looks like it will do the job but you have said you do not use a microcontroller and that is what converts the quadrature signals to up and down pulses. The microcontroller does the same job as the circuit that Tony and myself have already suggested. The encoder switch on the board is what has been suggested in many of the replies. The printed circuit board that you have made for your original design looks very well made so you should have no trouble building the circuit.
I found that you can buy the kit here. https://diy4fun.blogspot.co.uk/2010/01/rotary-encoder-for-ats-transceiver.html
