[TenTec] Need TenTec 238C Ant Tuner - very wierd antenna switch behavior

[dukeshifi]

Are you saying that, no matter what ;position the switch is in, that you can connect a single antenna to any one of ten four outposts and get signal through, or are you saying that, regardless of switch position, your signal only goes to one of the outputs?

It’s an important difference.

If the latter is the case, look at the coupler between the front panel knob and the switch itself to ensure that the switch’s own main shaft turns when the panel knob is turned.
