Try transmitting into a dummy load through a wattmeter to eliminate the antenna as a possible failure. Unfortunately, the power amplifier sections of these smaller radios tend to be undersized and are often the main point of failure.

I realize the trace under the components wasn't the issue in this case, but it is still bad practice. I personally avoid routing between SMD resistor pads (especially on smaller packages) because it is very easy for soldermask to scrape off slightly and make contact with conductive parts of the...

Nice work 3v0! Good to see you!
My old job was tossing one of its old solder pots (they just didn't need it anymore - still worked just fine) so I snagged it. It's a small one though, only holds a few oz of solder at a time, but is still larger than I'd need. I've considered putting in some...
