3.1 Transmitter Logs

Once per show the on-air DJ is required to record a set of readings from the transmitter to document that we are broadcasting within the required legal and technical parameters as defined by the FCC and to verify that all equipment is operating normally. Typically DJs take these readings during the last half-hour of their shows but it can be done at any time during your show.

How to fill out your Transmitter Logs:

  1. Find the Transmitter Log clipboard in the studio. Check that the Day and Date written at the top is correct. If your show goes past or starts at midnight you will need to start a new sheet for the day and place the old sheet in the stack of old logs in the transmitter room. Extra Transmitter Log sheets can be found in the transmitter room by the old log sheets and inside the storage compartment of the clipboard, if we are running low please notify the station manager. 
  2. Go to the transmitter room at the back of the building. This room is air-conditioned to prevent the equipment from overheating so always close the door after yourself.
  3. Fill out the time and readings for each setting: FWD(%), RFL, PAamps, PA volts and sign your initials. Do not press any other buttons on the transmitter except the ones corresponding to the log readings.
  1. At the bottom of the log sheet print your name, time on, time off, and your initials. 
  1. Return the Clipboard & Log Sheet to the Studio

Important Notes:

  • This is a legal document so it is important that you fill it out accurately and completely every time you are on the air. We could face fines or lose our license if there is a problem with the transmitter broadcasting out of spec or the records are not accurate.
  • If the readings seem unusual please notify the station manager. See above for a typical reading but remember that there is some natural variance for each setting. Sometimes during bad weather we broadcast at half-power, if this is the case make a of it on the log sheet.
  • Emergency Alert System (EAS) tests and activity, such as tornado warnings, must also be logged. See the Emergency Instructions for more details.
  • Carrier On / Carrier Off: Because WDBX broadcasts 24/7 you should never need to do a carrier sign-off. In the unlikely event that we need to take the transmitter off the air the Station Manager or Engineer should be there to help. Information about emergency shutdown procedures for the transmitter can be found in the Emergency Instructions.
