While a soldering iron and a screw driver is all you need to setup the ubitx, i would encourage everyone to experiment with testing and measuring.
A resistive swr bridge is just three resistors and a transformer. An RF voltmeter is a diode and a capacitor. An HF oscillator is a one evening project. Raduino, with a different firmware can be a programmable signal gemerator and a voltmeter too. Each of these kind of projects will enhance your understanding and bring immense joy to your hobby.??

I haven't seen a lot of flames here regarding imprecise measurements. If you have the Harbor Freight digital voltmeter (often free with any purchase), you are about as well armed as most folks here in the forum.? If you have trouble troubleshooting, somebody may urge you to build a diode RF probe, that's about it.
Some do have good lab gear and and decades of experience, can measure filter passbands or intermodulation distortion or harmonic content, and they then report back telling us what they saw.? But that sort of thing is definitely not required. If anybody suggests you should spend more on test gear than you did on the radio, that's your opportunity to go ahead and flame them good.
