Hi Zen Mod,
Dead end chip set, very similar to my Nak OMS-7. Surgery time. I am attempting the same thing you are.

hehe
even venerable,just too nice toy to abandon .....

I'm looking for non-os surgery and certainly some butchery after TDA1541.....those 8 legged fuses are like bugs.....I'll replace them with something simpler fer sure

....who knows,mebbe even some repeater coils on output ,just to add some spice

I'm still thinking of taking the RF signal and feeding it into another pcb in parallel (with buffers of course). Using a more standard chip set I could get there. All you need is a dremel with a cut off wheel and a car CD. Route the RF in and take your digital signals out. Taaa Daaa!

Hi rfbrw,
Thank you. I read that thread, but I want to go into BB land. PCM1702 would be my flavour. I plan to leave the servos functioning as they are for now (7020 stays).

Do you mean the SAA7030 digital filter ?

anatech · 31st August 2006, 02:45 PM

Hi rfbrw,
No, I did make an error though. I meant the SAA7000, SAA7011 and 7020. Not unless I create another clock source. The SAA7000 is the master clock for the system.

So SAA7000 to 2x PCM1702 or SAA7000 to SAA7030 to 2x PCM1702 ?
