Hi
Has anyone had any experience of building / using a DDS VFO ? (I saw the
previous post from SP7EWL). I reserached the possibility of using a DDS VFO
in a home brew TX/RX I want to build, and would appreciate any comments.

I hav a dds daughter card from the njqrp club
and the picel from amqrp.

they work together to make a dds vfo.

I looked at it on my hp 140T/8555 spectrum analizer
and I could not see any spurs on my analizer.
(not exactly the best combo for this job realy designed for microwave).

amqrp has the schmatics online at therir site.

Good Luck
