PIcked up a couple of large size Radio Shack 63-960 LED clocks with Settable alarm, at local Goodwill store. $3.00 ea work great see across room, loud Alarm, etc...
Barely missed, by seconds, getting a classic Hallicrafters General coverage receiver (not like say, S-38) but a larger light green metal box. nearly perfect condx. $25.00 with the famous h logo speaker probably late 50s Vintage. :-( Dang... Checked LED clocks by ear and eye with WWV, They drift a few seconds in the course of a few days, and wander back and forth. Thought AC mains frequency was tighter than that. They use an LM 8560 Clock chip. Uses a switchable AC mains frequency reference pin 50/60 hz. Want to provide an accurate (relatively accurate) 60 hz reference to the chip. Some room inside for custom modifications. Does a TCXO or similar exist in a small package that provides 60 hz ticks?
