Arduino based DDS with 898 Eddystone dial
Hi All
Just looking for any suggestions . Currently contemplating build a ham band rx using a combination of DDS VFO the frequency of which is controlled by a mechanical dial (I have a mint condition Eddystone 898 which is collecting dust and seems a shame not to use) I already have the DDS up and running with LCD and Arduino sketch. I am thinking of connecting a pot to the 898 to provide an analog reading to the arduino to indicate physical position of the dial, then use that value to give "startup frequency" to the code. The encoder, also connected to the 898 would then move the dds frequency up and down. The rest of the reciever would be valve based.
Does anyone have any better ideas on how to use the 898 dial to control the dds frequency ?
Just think it would be nice to make an accurate stable receiver using old and new technology and a nice vintage dial with the option to switch to lcd.
