You may find that there will noise in the receiver that is not related to the Microcontroller at all. You may find that the noise is related to spurious signals from the DDS. No DDS is perfect. All of them have some frequencies that have significant spurious signals in the output. Ken - AE1X

Hello Ken. Some of it migth be DDS noise, but the noise dissappers when I remove power to the PIC miccrocontroller. This way the DDS stil generates the Lo signal. best 73's de Thomas LA3PNA. 2008/11/12 Kenneth Stringham <ae1x@yahoo.com> > You may find that there will noise in the receiver that is not related > to the Microcontroller at all.

Hello Ken.
Some of it migth be DDS noise, but the noise dissappers when I remove power
to the PIC miccrocontroller.
This way the DDS stil generates the Lo signal.
