Low Power FM Site Monitoring Kit Keep your station fully compliant with FCC rules! FCC rules for unattended operation of LPFM stations require that all installations have a tamper-proof monitoring and control system that allows the transmitter to be turned-off within a short time in case it malfunctions and causes interference to other services. (See quote and link below for more details.) Davicom manufactures such a small remote site monitoring and control unit that is a complete solution for unattended LPFM operation as per FCC regulations. This unit, the DV-Micro, was specifically designed for small station requirements and it has an attractive entry-level price that does not compromise on necessary features. In addition, this unit is not a dead-end device since it can easily be expanded should your station requirements grow in the future. The DV-Micro kit includes everything needed to remotely operate and control your transmitter. It comes with a built-in telephone modem, voice response system and network interface for Internet connection. The kit also includes the remote-access software, an interface board, a 12VDC power supply, as well as all the wires and cables needed to get your installation up and running. For even more monitoring & control power, combine the DV-Micro kit with different sensors to monitor almost any parameter such as RF power, AC current, AC voltage, AC frequency (single or 3-phase), temperature, humidity and many more. Many of such sensors are part of Davicom s ever expanding line of sensors. The DV-Micro can be used to control LPFM transmitters from (but not limited too) manufacturers such as Nautel, Elenos, Harris, RVR, Crown, Sielco, BE, Eddystone, BEXT, Ptek, Technalogix, Armstrong, BW Broadcast, QEI and Rohde & Schwarz. It can also be set up to automatically shut down or restart an erratic transmitter and to send alarms by phone, e-mail or text message to station personnel. Optional equipment, also available from Davicom, includes: Battery-backed power supply for low-cost UPS functionality. Rack mount tray. Intrusion sensors for doors and gates. Indoor and outdoor temperature and humidity sensors. RF power sensor. Expansion module for additional input and output points. A FM broadcast monitor for modulation, frequency and audio monitoring 1

It measures received signal strength, FM deviation, carrier frequency and can generate alarms if any of these exceeds your thresholds. RDS/RBDS decoding is also included. Alarm contacts are available for stereo absence, high deviation, low deviation, low power & carrier frequency drift. Ordering #: FMBM-01 About Low Power FM Monitoring requirements 5
The following is a quote from LOW POWER FM STATION SELF-INSPECTION CHECKLIST, which can be found at: http://transition.fcc.gov/eb/bc-chklsts/eb18lpfm06_2008.pdf. UNATTENDED OPERATION : Unattended operation consists of using self-monitoring or automatic transmission system (ATS) monitoring equipment to control the transmission system, or alternatively, operation in the absence of constant human supervision with equipment that can operate for prolonged periods of time within assigned tolerances. In the former case, equipment must be configured to automatically take the station off the air within the required 3 hour time period after an out-of-tolerance condition arises. In the latter case, the licensee is required to make certain that the station is monitored frequently enough to ensure that station operation is corrected or terminated within the designated 3 hour time limit, but constant human supervision is not required. LPFM stations that operate unattended will be required to advise the Commission by letter to FCC, Media Bureau, of the unattended operation and provide an address and telephone number where a responsible party can be reached during such times of operation. Licensees should maintain a copy of any such letter with their station records. [See 73.845, 73.1400(b) and Report and Order in MM Docket 99-25, FCC 00-19, released January 27, 2000, p117.] NOTE 1: A Media Bureau Fact Sheet on Unattended Operation may be found on the Internet at http://www.fcc.gov/mb/audio/bickel/noonehome.html. NOTE 2: The 3 hour time starts whenever operation exceeds any tolerance. Therefore, the licensee should make certain sufficient monitoring is in place to detect and correct out-oftolerance conditions within this three hour period.
