You know those chip clips that techs use on computer chips to test /
troubleshoot the chips?

Why not do the same thing to PLL's before actually wiring the final
connections when expanding channels?

It would work, use alligator clips or wire wrap the wires around the pins
that match the designated pins on the PLL chip and then use some switches to
test the switching of channels.

Try it out.

Better than wiring the whole thing up and making the wrong connection.


It would be much better to build a jumper board, move the chip to the
jumper board, install a socket in the radio and plug the jumper board
into the socket. No traces need to be cut, and the board can be easily
removed and replaced with the chip.
