Hi all, I have a couple of the 10 MHz fixed output versions of the FE 5650A Rb module, that I use in a radio channel sounder.
One has now started to fail to lock, rather randomly. Sometimes it will burst into life, more often not. There’s nothing visibly amiss inside, but I hesitate to start random tweaking, despite the tempting-looking line of multiturn pots on the middle (VCO?) board . Given the amount of other data on the web, here & elsewhere, on similar devices, I’m slightly surprised not to have come across any schematic of this unit yet. If anybody has any pointers or suggestions I’d very grateful 😊 Cheers Richard _______________________________________________ time-nuts mailing list -- time-nuts@lists.febo.com -- To unsubscribe send an email to time-nuts-le...@lists.febo.com To unsubscribe, go to and follow the instructions there.
