[time-nuts] Lucent RFTFm-II-XO

[Chris Waldrup]

Hi,

Regarding the Lucent box- I wanted to let everyone know that once it locked to satellites, I have a 10 MHz out. 
The output was a square wave with some ringing, but I built a three element low pass filter and now I have a really nice 10 MHz sine wave. 
Thanks to all!

Last question.... I see it has a RS-422 output on one of the connectors. If I build or buy a 422 to 232 converter can I expect to be able to view the unit's data output with something like Lady Heather or Tboltmon? Or at least see an output with Hyperterminal?

Thank you.
