uBITX radio - spurious emissions warning

Post by TacAir » Fri Oct 05, 2018 12:59 am

This radio has enjoyed brisk sales in North America owing to the $109 price tag.

Turns out, you should stop using the radio owing to spurious emissions (harmonic related) that do not meet US regulations.

Spurious emissions (spurs) generated in the double balanced mixer at 45 MHz that exceed US emission standards on SSB above 18 MHz. This issue is exacerbated by higher audio drive levels (e.g. if you have added a mic preamp or voice compressor). This issue is an unnoticed design issue.
