have a couple of Minitor II's lying around a trying to figure out what freq. they are set on. any idea on how to figure it out? have taken them apart and know were the channel crystal is but does not have a freq. listed on it. thanks

pulled another pager apart and it has the following numbers on the crystal. How are these deciphered? A chart? thanks

63960
X6300
T9313

According to my calculations without looking at the schematic, the freq is 154.430 mc/s.

i have been looking around. and found the following out:

For VHF
Multiply the frequency stamped on the Motorola crystal by 3.
Then add 17.9.

is this correct?
if so what is the formula for UHF and low band?

thanks
