[time-nuts] FTS 1050A What to do??

Tue Aug 9 17:00:46 UTC 2011

Any chance you can trim the frequency to 6 Mhz with the thumb wheels ?   (Probably not but I'd be inclined to try.)

If you can get 6Mhz then dividing down to 1 Mhz should be easy.

On a side note I've been very pleased with the FTS 1050 I picked up from an auction site several months ago.  It's stability seems to be getting better and better every month.
