I am looking for a contruction artical or some other starting point for
a solid state 5 to 5.5 mHz. VFO to use with my PSK-20. Hopefully
somebody can point me to a contruction project, a kit or a source of a
VFO.

Google W7ZOI Progressive Receiver or check any ARRL Handbook from 1987-1994.
Mine has a worst case 5 minute warmup of +150Hz and stable +/- 20HZ
therafter in any 5 minute period.

QST June 1991 pg 27 has a VFO that does 5.0 to 5.5 mhz.
