Hi all, I am new here!
I would like to modify the rx of my Heathkit hw-7 , leaving the original front panel and case. I like to use a simple Quadrature switching mixer , thus, eliminating the common dc reciever hum, keeping the original analogue dial , feeding the existing af amplifier. Using a modern DDs or SI5351 or 570, replacing the existing variable tuning capacitor with a shaft encoder.
Any ideas please
Paul
