At 10MHz, a very robust toroid wound transformer is easy to construct and can
provide several KV of isolation, with little signal loss. Any low loss powder iron
core and 15 or 20 turns of silicone rubber insulated wire will suffice for signals
up to 1 or 2 Vrms.

I've been reluctant to put a GPS up there with a direct link to the shack and computers, etc. Has anyone done a simple circuit for conversion from a 10 MHz signal into, say, TOSLINK or such and then back for a galvanic break? I realize that I'll be adding some delay and jitter, but for frequency locking shouldn't be a problem.
