These are super easy to use. At the back should be two co-ax sockets marked in and out. Take a piece of coax fly-lead and connect the antenna output of any radio to the In connector, then plug the antenna into the Out connector, so that this device is sitting in the transmission line between the rig and the antenna. Voila, that's it. Try not to let the trace go too much off screen... won't work well above about 30MHz and check the manual for max power, but normally these are fine at least up to 100W.

How much?

I’m don’t think these oscilloscopes are easy to use. I think they’re a pain in the ass. A good beginner’s oscilloscope should be set-up like a multi-meter; with basic resistance and continuity tests at the top. Below would be current, including different sizes of clamp-on ammeters. And a pair of test leads. Then quick performance tests for resistors, diodes, transistors, and capacitors. Then logic gate tests. Young men need a progression of ideas, starting at the very beginning. The world run on relays connected to other relays connected to other relays. It would be fun to make a mystery game. Each cardboard panel has a few components, and a problem.

This scope is meant to just be a nice accessory to the Yaesu FT-101 lineup.
