New Life For Old Digital Clocks



This Does Not Pertain to Satellite But This Maybe Be Useful for all radio operators


I had a couple of extra digital clocks at home and I needed two or the ham 
shack (Local,UTC)
I wanted both clocks in 24hr mode,so I Googled the clock IC used in the 
digital clock,and found most of the using a very general purpose clock IC
and all capable of doing 24hrs format buy a small modification,usually this 
mod is just a matter of shorting  a couple of pins on the IC
My IC was a  LM8560 so all I had to do was jump pins 15 to 28 to make the 
clock work in 24hr mode
works great,now all I have to do is glance at the clocks and with an 
instance of have both times .I know its an easy conversion to do in you head 
but this makes it much more convenient and its  a way of using some of the 
old stuff around the house and utilizing it rather then throwing it away or 
even better having to buy two clocks for the ham shack
Just my contribution to the group
