This has given me some ideas for synchronizing signals around the shack, including the use as an ultra-high stability reference for my RX-340. The stability of the RX-340 is exceptional, but I like t

My RX-340 is currently about 10 Hz from zero beat at 15 MHz. Not bad since I have never calibrated it. However, a simple pot adjustment will bring it back to zero beat and will likely stay there wit

What's the advantage of that solution over the GPS' 1 part in a billion accuracy and more importantly, what assurances do you have relating to accuracy and stability without lab-grade test equipment?

After inspecting my serial port mods to the Z3801A, it appears there are no operator errors after I made the internal RS-422 to RS-232 mod. I am using a standard RS-232 DB-9 to DB-25 serial cable (e.

After 24 hours, the best 1PPS TI I can achieve is about +100ns even with the GPS lock indicator on. Although accuracy into the Ten Tec RX-340 is still excellent, the margin of error is still no bette
