Subjecting a Hughes module is pointless - the Pulsars had a heat sensor for compensating their timing...no other's had that.
Your Hghues may need a new quartz crystal - I have a nice supply of that frequency an d would be happy to try a swap for you.
Does your module have a white-ish plasitc hub(battery holder)? That seems to be the most common arrangement, along with some marginally different button contacts.
And understand, when you go through the setting prcoess with that module, it takes 11 pushs of the setting button to get to "GO".
Leap year,month,day,hour,minute, 5 for the five line of text, finish. Commonly people are still in the settings and think they are done, especially if there is any "stuttering" with the setting contact(bad contact)
Push it, push it real good

Couldn't resist!
