Utilization of Radio Frequencies at any HOTSS Flying Field

 Frequency control at the HOTSS flying field shall be the responsibility of all members and guests who wish to fly at the field. No person shall turn on a radio transmitter at the field unless he has in his possession a frequency clip from the clip board provided by HOTSS, or - if no clip board is available - he has determined by talking to all other flyers at the field that the frequency that he wishes to use is not currently in use.

Frequency Control during Contests or Other Events Open to Nonmembers 

During contests, fly-ins, or other HOTSS events which are open to nonmembers of HOTSS, frequency control shall be by standard methods such as transmitter impounds.
