The 10 Mhz reference will only be utilized when the radio is initially turned on. I dont know why they would design it this way. I have a GPSDO that can supply precise 10 Mhz all the time. Why not use it all the time?
The 10Mhz input on the radio is constantly referenced, not just when the radio is turned on. In Auto mode, the radio monitors each of the inputs and selects an input that offers a signal in priority order. The highest priority signal is the External 10 MHz signal (optional), followed by the GPSDO signal (optional), followed by the TCXO signal (always provided). The radio will track changes in the availability of the signals. For instance, if the External 10 MHz signal appears, the radio will switch to it from the GPSDO or TCXO signal.
Hi Mike: If I use an external reference then I don't need to worry about these steps? Do I disable the offset somewhere if I did the calibration then added an external reference afterwards?
Keep the short tip videos like this coming. Thanks.
working on it!
That is what the Marketing team wants us to do.
I have heard a lot about Flex Radios as the next level among SDRs, from my local ham colleagues. Yet to see one. 73 de Jon, VU2JO
Hello Mike, as always thanks for this tip.... 73
Great reminder thanks
Yes, that is good to know.
Is there any info on how often we should re-calibrate? Does it even matter?
Not really. It is good to check once in a while, but I think you'll find it pretty stable.

You just set the offset to zero.
Thanks ....
You're welcome!
