Try as I might, I never seem to run out of projects that demand a good quality SO-239 panel connector!
Even though these are bread-and-butter components, they can be suprisingly expensive when bought through mainstream ham outlets.
Last week, I gave a try of some panel connectors via E-bay, which come directly from China. Remarkably, within a few days, they arrived in the post.
Just under £12 for 20 connectors is pretty good value in my book.
Here's what they look like in the flesh. Very well formed threads and teeth.
