Surecom SW-102 and the Wouxan KG-UV9GX

[ChaosActual]

Howdy folks, I was hoping someone could point me in the right direction on some cables & adapters I might need to test my Wouxan KG-UV9GX on the SW-102. I bought some cables from Amazon but the little bastards heads are too big & cannot plug into the SW-102. Any and all help is appreciated.

You'll need a couple of "N" male to SO239 adapters.

I'm assuming you mean into the radio.

I think you're looking for something like this.

Would you mind clarifying which version of the sw-102 you have?

I've seen both so239 and N-female versions, and the two connectors aren't interchangeable (though you can go from one to the other with adapters).

that one specifically. I’m just lost in the sauce about the connector types.

The connectors on that meter are N-female...it looks like it should have shipped with adapters to convert to so-239 (aka uhf female).  If not, here's a cable that should be what you need to go direct from the meter to your radio: https://www.amazon.com/SDTC-Tech-Coaxial-Extender-Connector/dp/B07NY2VVBZ/

Edit: here is a decent chart of the different connector types https://www.air802.com/connector-identification-chart.html

If you want to see SWR of HT antenna, save your money. It's fool's errand. You can't get any meaningful measurements with SW-102 or any other meter, it is simply not possible. You can test power output into the dummy load, though.
