GPSDO Setup Flex 6700

WNK

I have a Leo Bodnar reference clock set up for 10mHz but I'm not sure what voltage level to set it at. The range is 8 to 32ma. The Flex SDR Software guide says I should be at about 5 dBm. I'm not sure about the conversion of this.
Second,,,does SmartSDR retain the offset from the previous OCXO calibration if it reverts back?
And third,,,I have User Guide version 3.1.7 and it shows in the radio setup window a place to select Auto,GPSDO or TCXO. I don't seem to have that option on my 6700.
Any help here?
I've attached a picture of my "RX" window.
Thank you in advance.
73 and Aloha, Bill

Output power level (measured at 10MHz, fundamental power channel):

+13.3dBm, drive setting 32mA

+12.7dBm, drive setting 24mA

+11.4dBm, drive setting 16mA

+7.7dBm, drive setting 8mA

Those settings you don't see are only on the 6400 and 6600 models.

Your other question about reverting back to the last calibrated offset, I will let someone else answer because when I was running an external GPSDO I always calibrated with the gpsdo active. Also if you have read about the 6700 with external GPSDO some have had issues with it kicking out, I am one of those that had this problem so I opted for the internal GPSDO.

When using an external reference, there is no requirement to calibrate as the external reference is considered calibrated.

The calibration only affects TCXO or the OCXO in the radio. The TCXO or OCXO are not used if there is a GPSDO or an 10Mhz external reference available and selected.

On the 6700, the source of reference is automatically selected when you boot the radio.

Thank you both for the reply's. I now have a much better understanding of the GPSDO.

So you both have answered what I needed to know. THANK YOU BOTH for taking the time and hope to see you in my log as the cycle improves.

Aloha and 73,
