I wish to take the 10MHZ output from my F6.7K and send it to some other devices in the shack.  If you are using a 10MHZ distribution amplifier, what are you using?  Did you build your own?

I have an HP5087A distribution amp. It's nice since it can hold up to 12 modules and they are individually adjustable for output level. The option 004 is all 10 MHz modules, but you have to be carefull since some eBay sellers don't know what modules they have inside.

From the FLEX-6700 + GPSDO I use a Stanford Research Systems FS730/1 distribution amplifier.  The Center frequency is 10 MHz and the 3 dB bandwidth is +/- 200 kHz.  It is an excellent piece of equipment.  The FS730/1 provides 7 outputs and I use them to provide reference signals to a spectrum analyzer, signal generator, oscilloscope, TS-990S, IC-7800, and a little FLEX-1500.

I also have the DEMI 10-4 which I use on another bench.  It is a good buffer amplifier.  No distortion when comparing the inputs to the outputs.  The DEMI 10-4 provides filtering for harmonics but it does not provide narrow passband filtering like the SRS FS730/1.  If you have a good clean reference signal the DEMI 10-4 is quite a bargain.

I use a video distribution amp I bought on eBay for $20.

I use it to run the 10 MHz reference signal from my GPS clock/timebase to all my test gear.

Works great, and there's no drop in the signal level going through the amp.

Another vote. For the DEMI unit. It's what I use.

Question:  Is the 10MHz reference signal available when the Flex is off, but has power supplied?

Yes.  If the power LED is amber, indicating it is in standby mode it should be putting out a 10 MHz clock signal.
