    Yup! That's what I did too, just not as nicely packaged. What was the intention of the switch originally?

    In some photos of the original NNTN6367A flash cable there is a flash switch. I guessed that it turned the +12VDC on or off and decided to replicate that funtionality to see what it did.

    It turns out that connecting to the DTR radio when the +12VDC line is off allows it to show up as iden modem to the PC. However, there doesn't seem to be anything useful about that so the switch is not required.

    10-4. I had a few of the "real" flash cables. I had thought (in my hopefulness) that switching the switch the other way would turn it into a CPS cable. No such luck. No idea how the other mode would be useful.
    It would be interesting to make an adapter that was dual-purpose that way. I have a bunch of USB->RS232 circuitboards.... hmmm....
