hi,
As the high MSF and EMS are expensive in the UK, I decided to see if I could pick up the 1 second pulse
from a MSF wall clock, dial type with hands, value about £8GBP
I discovered on the back of the MSF module a small sticky label.
Peeling off the label revealed a 2 pin male connector, 0.1inch pitch.
Scoping the pins gave a 1second regular pulse, about 1.5V in amplitude.
After I had removed and replaced the battery, the clock started to adjust for the correct time.
During this time the pulse rate increased until the clock was correct, then a 1sec regular pulse.
This a very low cost way to get a MSF 1 second sync signal.
EDIT:
Checked a second MSF clock from another supplier, that also has the 2 pin male connector.
This must be a factory test feature, so its probably on most clocks.
