i have 2 of those units with the 1 Ghz option.
old but very nice with the hard line feeds in side ect. )
P.S.,
make sure you lubricate the range selector universal because the
original grease (safe for plastics) tends to harden up. also check for
alignment and make sure there isn't any slack between the joints.




Dumb question time...how do ypu ID the card that has the 1 ghz option.
As of yet, I have not powered up the unit for more than a few seconds.

Thanks for the tips. I also found info on the problems with the delrin
gears.

Hmm, i not sure about that, i also got these 2 units from ebay, the
selector dial has the 1024 position on it, when you snap the switch over
to the mode your freq counter should display it.
as far as i know its simply a doubler module put in there.
