Thats because everything is supr-dupr secret in them. I have a mighty seriously dead z3801. I picked up for $ zip. Well fact is its still mighty dead. :-) I am generally pretty good at reverse engineering. But when it goes in the micro or asics or fpga's. Life gets near impossible especially with out anything but your eyeballs. But my interest in the dead one was to explore. Have to say the dual ovens well done but what an ungodly mess. The insulation stuff gets sticky like tar after years. The Z3801s issue was however in one of the ASICs. Such is life. Yes you do need satstat at least or the z38xx program from germany. Its free and at least would give you a clue.
If you are lucky the DAC is at the top or bottom of its range that happens. You need to take the oven apart and adjust the course frequency. Ugly issues Taking the oven apart, ultimately putting it back together Adjusting teh cap. Since it has not been moved in 20 years you can be sure its going to go noisey on you. Then you have to adjust to get the DAC back to mid range. Patience. Regards Paul WB8TSL On Tue, Nov 18, 2014 at 3:17 PM, Don Murray via time-nuts < [email protected]> wrote: > Hi Paul... > > No...
