    Do you have internet full time? If so download Meinberg NTP software (https://www.meinbergglobal.com/english/sw/ntp.htm). This uses the NTP daemon and queries a list, you select, of time servers world wide. I use it for EME

    So, I hooked up my Chinese Communist GPS synced 10MHz
    reference to my Flex 6400. ( Many referenced here all seem to have the same insides. ) TX reads 0.9HZ high using my Efratom GPS enabled Rubidium frequency standard as the time base for my counter. Then I reversed and put the Efratom to the Flex and the Chicomm unit to the counter. flex still transmits 0.9 Hz high. If I sync the frequency counter with one reference and count the other it reads 0.0 ( Both output 10 Mhz ) But, when I calibrate the internal Flex TCXO at 15MHz the transmit frequency is dead on at 7195.500.0. Any Ideas our there?

    Tim solved my problem on the Facebook Group.

    Tim Ellison Do you have a TX calibration offset value that is not 0? Disconnect the external clock source and look at the frequency offset. It should be 0 if you are using an external source and the source is dead on 10 MHz. Otherwise, do a frequency calibration with a known frequency reference with the external clock connected.

    My Rb source is about 0.2 Hz high, so I have to you an offset to correct it.
