Default Re: Eddystone 750 digital readout

Here's a circuit diagram of an arrangement for adding a DFC to an HRO described on this Forum some years ago by the late Bob Green. It may have been that the DFC modules which were around at that time were less sensitive than the current ones, but this is an interesting implementation, putting the amplifier inside the receiver, but avoiding direct connection with the LO and using the same cable for the RF and DC.
