So, the mc4016P is equivalent to the mc 14016P. This is a 16 DIP plastic case, divide by N from 0 to 9. The one that is bad is U 706 in the divider board used as a counter, but there are several others of this type in the circuit. If the 1 in front of the 4016 means cmos, I suppose they will work in this circuit. A UV3 gets hot (no fans, no heat sink) and I think the heat just got to it. The 14016 is listed in NTE and others and I will try to get one locally. I will keep the list posted. Many thanks for the help.
It is interesting to read these threads and I imagine that all of this brain power helps keep the list members sharp; all for a common Drake cause. Thanks again. Incidentally there are factories in China that sell these... Had several emails within a few hours responding back to me. I guess they have active mining software running all of the time. Go figure.

Guess you have to look and see what the circuit is! The standard CMOS chips are CD4016, which is a Quad Analog Switch. Motorola's version is a MC14016, which is why the 'extra' 1 at the beginning. I seem to recall now that Motorola DID have a series of 4000 chips, much like the 10000 series MCL. The TR-7 uses about a half dozen of the MC14016 (CD4016) switches. Thanks for the clarification, ya gotta look at the diagram to be sure. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 2-C/2-NT, 4-A, 4-B, C-Line and TR-4/C Service Supplement CDs <www.k4oah.com> Curt Nixon wrote: > Well..that may be true but here is the motorola datasheet for the > MC4016 > > It is indeed a Mod N divide by counter..
