Re: [time-nuts] FE-5680A Schematics (v0.1)
FYI Schematics for the 60MHz to 10MHz out divider, directly behind the DB9. There are 3 selectable output signals on the mini RF connector, either 10MHz or 60MHz (Square) and 10MHz bandpass filtered http://i1090.photobucket.com/albums/i370/bobgrant1/TimeNutz/clockout.png Bob On Wed, Feb 15, 2012, at 12:53 PM, Bob Camp wrote: > Hi > > Some of the schematic is less important for "how it works" but all of it > is > useful for troubleshooting.

Re: [time-nuts] FE-5680A Schematics (v0.1)
Hi Some of the schematic is less important for "how it works" but all of it is useful for troubleshooting. I wonder if splitting off stuff like tracing out the power supplies and heaters might be a good idea... Once we get into things like typical voltage levels, we will need to look at multiple units anyway.

Elio, I've contacted with the guy who dissected his FE-5680A in YouTube. I offered to pay the shipping and he agrees to send the board to you, so he needs your address. Please contact directly with me.
