Default Re: DDS Xtal Replacement

Thanks all. Think I need to open the radio I was looking at generating the LO digitally for and get on the air (a Decca Messenger) instead of just working from the service manual, to see how much space there is inside. TBH the LPF does look a little on the overkill size at 10W to help replace a xtal... Although a boxed external variable source with an LCD does now sound an attractive, and more versatile, option.

Noted re the 3.3V/5v oscs.
