[SBE] Unattended operation

[Dan Rapak]

Was this time limit always 3 hours? I'm trying to recall what the "fail-safe" timeout was on our remote controlled transmitter was when I worked in local television in the late 1970's.

  There are three modes of operation, Attended, Automatic Transmission, and Unattended.  Many times ATS is mixed with unattended but they are different modes of operation.


  So from 73.1300, Unattended is:


  "or unattended (where highly stable equipment OR automated monitoring of station operating parameters is employed). No prior FCC approval is required to operate a station in the unattended mode."
Note the "or" between highly stable and automated monitoring. Note there is not any requirement for automatic shutdown if the system goes out of tolerance. So if it's highly stable it won't go out of tolerance will it???73.1350 (d) does require shutdown after  3 hours of ANY broadcast transmitter if certain conditions are exceeded,  examples given are EXCESSIVE power, EXCESSIVE modulation, or spurious signals. Which basically  means if it is causing interference to others, turn it down or off.Common sense,  yeah, best to have some way of remotely turning it off it sounds crazy on the air.
