I just had an interesting chat with the fellow who D&D electronics refers
technical support to.  His name is Tom Page.  He has developed a modification
kit (or instructions - not sure which) for the universal descrambler.  He
did give some ideas to help achieve stable lock-up over the phone.
 
1.  Change the trimmer caps to Radio Shack 273-1340A.

2.  Change R2 to 5K  RS 271-1714.

3.  Ground the case of the crystal to C22 ground.

4.  Change C21 to 1 ufd.

5.  Change c30 to 100pf

6.  If necessary add a "hot shot" switch that grounds IC6-10 momentarily..

I suspect that grounding the crystal and the C21 & C30 changes may help..

For more info you can call Tom at 407-799-4292 or can order his mod's
at:

KDA
PO Box 320404
Coco Beach, FL 32932

I really don't know if his mod kit is worth the $10 he wants for it - but
then again if it works...
