Nigel,
... would like to add a
DDS VFO with LCD frequency readout and re-package it all mainly for
PSK use. Looking for plans with PCB patterns and any hex code for a
suitable DDS VFO...

I have a follow-on for the Siggen project (i.e., Far Circuits board running
my Siggen3a code)
or my PICELgen code running the PIC-EL. It is going to be released by AmQRP
very soon.

My new DDS VFO (called IQ-VFO) has some significant advantages over the
previous
DDS VFO. This one uses a more advanced DDS (the Analog Devices AD9854)
which produces
two outputs (In-phase and Quadrature) on any frequency from 0 to 30 MHz.
The two signals
provide endless modulation/demodulation possibilities.

Full kits will be available as well as the bare boards, etc. My source code
for the two PIC
microcontrollers that control the IQ-VFO is also available so modifications
are encouraged/expected.

You can see detals about the IQ-VFO on my web page: www.cbjohns.com/aa0zz

Also, a few days ago I opened up a YAHOO group (called DDS-VFO) to discuss
DDS VFOs and
this IQ-VFO in particular. Please join us there.
