I think your an amateur trying to do an engineers job! Before you make any
decisions about what is doing what to what, how do you know your counter does
not drift? How do you know the accurace of your freq. counter? You checked it
against WWV? Heck, if your going to do engineering work, take your counter to a
qualified calibration shop and get it certified, not only for freq accuracy,
but for it's own stability. Then and ONLY then can you draw conclusions about
'something' drifting. And before you go way off base and spend your $50 bucks
because you want to play engineer, check the specs on your Omni 6. The Omni 6
is not a frequency standard, it is a AMATEUR radio piece of equipment. If you
want a frequency standard, HP sell's them for only about $125,000.
