It seems that a large number of taxicabs in Russia have been illegally using the 10-meter band for their communications, but nobody much noticed until now, as the rising sunspot cycle brought about improved propagation on the band. According to "Newsline," most of the cabbies were using channelized FM rigs. Russia's Radio Frequency Service has reportedly promised to crack down on the illegal users.
AM and SSB transmissions by non-amateurs in North America have also been reported. U.S. amateurs hearing illegal activity on 10 meters are encouraged to gather as much information as possible and then get in touch with the FCC's Enforcement Bureau.
