"Many things" is not specific enough. Can you be more specific? This used to be true of a few models of ham radios, but A) the manufacturers have largely fixed that situation, B) those were mostly sold as ham radios and we're talking here about COTS FRS radios, which are easily testable and there are no complaints I could find online, and C) these are also 2W LOS radios which cannot legally be sold with a numeric keypad or be fitted with a new antenna. Not exactly a threat to local amateur operations... Oh and D) In years of operation I've never had a single problem from either others' spurious emissions affecting my operations or FRS users on the ham bands.
