Surprised to hear race activity this afternoon on 164.8875 which is also the Secret Service "Oscar" frequency. Traffic consisted of a television/movie director talking to helicopters and motor units as the race headed into the final several miles east of San Jose. The talker had a British accent and there was talk of a British flag, so perhaps this was a British production and the frequency they were using was for tv/movies ops back home. Be interesting to see if the Feds launch a complaint. The transmissions were solid with few breaks (i.e. no release of the mic) and were coming from a helicopter or airplane. Copy was too good to be from a mobile unit.
