I want to build a frequency standard, not too bothered about the actual frequency, maybe 1 mhz, for callibrating my test gear and maybe connecting up to my frequency counter (would need surgery), also I have a pendulum master clock from a bt telephone exchange that I'd like to sync too.
I've seen these rubidium oscillators on ebay, however I suspect that these are probably toward the end of their lamp life.
I have a schematic for syncing a 10mhz xtzl osc to radio 4, here in the uk is broadcast on 198kc and the carrier is locked to an atomic standard.
I've also considered building a receiver for the msf time code signal on 60kc, but I dont know if I'd be able to get that to work well as the transmission uses amplitude shift keying, I thought of just receiving the signal and then squaring it, but I suspect theres going to be issues with noise with the signal strength all over the place.
I have built several unusual clocks using a symtrick msf receiver, I get a good signal as I'm about 40 miles from the tx.
Any suggestions?
