Question for you guys. This DDS Kit wants 5V for the Encoder. I'm planning on using a 7805 Regulator to provide that 5V since I am unable to find 5V in the radio. I am going to need to mount it to something and that means chassis. Can you mount a voltage regulator with-out insulators to ground (Mount the tab with screw, washer and nut) with-out creating havoc?
