Drivers Tested To Comply With Fcc Standards Part
It generates, uses, and can radiate radio frequency energy and has not been tested for compliance with the limits of computing devices pursuant to part 15 of FCC or ICES-003 rules, which are designed to provide reasonable protection against radio frequency interference. Operation of the equipment may cause interference.

3 years agoApparently the ARRL set up a Spectrum analyzer at Dayton the last few years and offered to test attendee HT's for spurious emissions. FCC Part §97.307:
(e) The mean power of any spurious emission from a station transmitter or external RF power amplifier transmitting on a frequency between 30-225 MHz must be at least 60 dB below the mean power of the fundamental. For a transmitter having a mean power of 25 W or less, the mean power of any spurious emission supplied to the antenna transmission line must not exceed 25 µW and must be at least 40 dB below the mean power of the fundamental emission, but need not be reduced below the power of 10 µW. A transmitter built before April 15, 1977, or first marketed before January 1, 1978, is exempt from this requirement.
At Dayton this year, only 25% of the Baofengs that were tested, complied with Part 97. 21% of Baofengs were borderline, and 54% of Baofengs were non compliant. 86% of Wauxon's were compliant and 14% of Wauxon's were not compliant. Yaesu, Icom, Kenwood, and Connect Systems: 100% were compliant with the Part 97 standards.
The ARRL concluded that many of the radios that did not comply, would cause harmful interference with other radio services.
