30 mating cycles ?? That gets you through the Demo Board only
twice !!

Where can one get extra cables, I think I may need them if I am
to use the Demo Board to show off what the NanoVNA can do.

looks like 23 more cables to order and fix them permanently on to sma patch panel, I don't want to take on and off these, knowing in the past these connectors are not continuous use parts. Thanks for the part number.

Found a better price here for bulk. I'm use to lab prices so these are pretty cheap but not going to use constantly just for demo and test theories.

I bought a couple of demo boards for classroom teaching and they didn't even last out the day with my students. A lifted trace on one board and intermittent cable connections on both boards after use by my better students. For a teaching environment, I would suggest something sturdier like the SDR-Kits Testboard Kit, or as you suggested permanently attached and fixed in place demo board cables.

Hi Herb. I made a simple tool to install the board side connectors, but also doubt they will survive very long. My first thought was to solder them onto the board, but that would probably cause the small connector to lift off.
Perhaps some epoxy or super glue? I could make a 'dam' around the outside of the board and fill it 1/8" or so with clear fiberglass resin.....

Ron,
Thanks for the suggestions. Both boards have been donated to students for their own use. I relegate this to the same pile as the other cheap Asian electronics I've purchased that didn't live up to their promise. The success of the NanoVNA and its derivatives caused me to let my usual guard down. I generally wait for user reviews from the first wave of buyers before recommending a purchase.
