Yes.

When the radio boots, the current software will auto-detect the presence of an external 10 MHz reference input that is above the minimum input level and use it instead of the internal OCXO (6700)
or internal TCXO (6500).

It does this at boot time, so if you apply the 10 MHz input after the unit is already running, it won't use
the external input until the next re-boot.

If the radio is using the external input, and you remove it during operation, the radio will fall back to the internal reference within one second. If the external 10 MHz then re-appears, it will not be used
until the next re-boot.

And the external GPS can be used with present software, right?

Hi Jerry:

The 6700 has an external 10 MHz input on the rear panel. It is an RCA jack on the upper left
side of the RCA jack cluster on the rear of the radio.

Input level specs are +4 dBm  (1.0V) minimum, to +15 dBm maximum.

If you would like to download the hardware reference manual for this product,
please go to our website, and look under "Documentation"

Do I have to get the Flex GPS option to get GPS stability?
