Interesting. I guess what I'm worried about more than the voltage, is the ability of whatever is supplying that signal to be able to drive a coax cable. Also, you will have some problem with impedance characteristics of the RP56's circuit vs. a 75 ohm connector.

Anyway, I'm trying this mod, and I soldered togeter a voltage divider that will come out at about 75 ohm impedance. It uses a 100 nF cap, two resistors, and some inverters to drive the output. I'll let you know how it works....
