I use a Rubidium standard with my Flex. I did nothing special to interface it to the flex. Just wired up a cable to the output....I believe that it is a sine wave. I used a small, open frame supply for the power....ordered it from the internet. If you look up the Rubidium unit on line, you will see the voltage range that is acceptable. I did mount the standard to a heat sink using heat sink grease to insure a good thermal transfer.
I suspect that you can just make a "Y" cable to connect to two radios. I am going to also interface it to my PTS 160 via an isolation circuit that I have not built yet. It works quite well with the F5K.

My F5K user manual specifies the level of the input signal, but not the type. 1. What is recommended Squarwave or Sinus? 2. What is the impedance of the F5K input? 3. Beside the F5K have a Flex-1500. What is the recommended way of hooking both Flex radios up at the same time? 4. What are other users using for the 24V 2A PS? On the last item I was thinking of reworking a 12V PS with a voltage doubler. Wonder wat others have done. 73, John ve3dvv _______________________________________________ Flexedge mailing list [email protected] http://mail.flex-radio.biz/mailman/listinfo/flexedge_flex-radio.biz This is the FlexRadio Systems e-mail Reflector called FlexEdge.
