SignalinkUSB cable for military radios
Are you a commo guy in the military, or a civilian with a
surplus military radio? Are you wondering how you can
quickly interface a Signalink USB to that military radio for
amateur digital operation?
Look no more, the answer is easy, explanation and diagram
below.
If you need to connect a Signalink USB to a PRC-150,
PRC-104, PRC-117, PRC-119, etc, you'll need to get a
U-229/UG1connector to solder up your cable. (It's that
connector that hooks up your handset or other device to the
six pin connector on the radio). If your commo repair shop
won't give you a spare, you can order them from Newark,
Mouser, and of course Amazon and eBay.
Connecting U-229 to Singalink USB with a CAT5 cable, just
install the jumpers straight across in the Sigalink, cut one
end off a CAT5 cable, and solder as shown below
