For those considering using the excellent dual output Leo Bodnar GPSDO, be aware that you cannot select certain combinations of output frequencies.
I have the dual output unit and it can be set for 10 MHz on one socket and 1 MHz on the other, which was ideal to drive my old Racal counter at 1 MHz and a signal generator that needed 10 MHz. However, it is currently set at 49.152 to lock an Icom IC-9700 via their add-on board, but the other output cannot be set at the same time to give 10 MHz for my K4D. The limitation is related to the synthesiser chip used, no firmware update will change that. I have done the KX3 extended temp cal and it works really well in hot temperatures. For the cal you really do need a very stable source, such as a Leo Bodnar unit. Incidentally, the K4 is stable enough for all except the most critical of users… I have other 10 MHz references but don’t both to connect them to my K4. 73 Dave G4AON K4D #286 -- Sent from my iPhone SE ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
