Specifications include, but are not limited to: The University of New Orleans desires to purchase a new solid-state FM/HD Transmitter for WWNO-FM. - Transmitter will be installed in a shared space where clearances are tight. Cabinet dimensions are limited to a maximum width of 36 inches, depth of 34 inches and maximum height of 72.5 inches. - Transmitter shall be capable of operating on either single phase 240 volt, 60 Hz alternating current or from a three-phase 208 volt WYE or 240 volt closed-delta power source, configurable in the field from single phase to three phase or vice versa with a simple wiring change. - Transmitter shall have a typical Corrected Unity Power Factor of 0.98 or better and this specification shall be valid in either single or three-phase operation. - Overall efficiency AC to RF shall exceed 70% at rated FM analog power, with an available output power of at least 16.5 kilowatts. - Overall efficiency with HD Radio in Hybrid Mode at -14dbc shall exceed 57% with available analog power output of at least 13.5 kilowatts. In HD Radio Hybrid mode at -10dbc overall efficiency shall exceed 52% and available analog power output shall be not less than 10 kilowatts. - Transmitter shall employ hot-swappable RF power modules and hot-swappable power supplies. The ratio of power supplies to RF modules shall be 2:1 to permit “soft failure” if one power supply fails. The DC voltage shall be distributed to the RF modules so that each RF module has redundant power independent from all other RF modules. A “common rail” form of power distribution is not acceptable. - Exciter and transmitter controller shall employ a redundant (dual) power supply configuration. Power supplies shall be interchangeable with the RF module power supplies and can be interfaced with an external Uninterruptible Power System (UPS) for brownout protection. - RF power amplifier stages shall employ solid-state LDMOS Field Effect devices. Exciter shall be digital, DSP based, direct-to-channel and shall directly drive the PA modules without an IPA stage. Exciter shall be fitted with the Exgine option at the factory for HD Radio. - Transmitter shall be supplied with a redundant (second) digital exciter with Exgine option factory installed. - Transmitter shall be capable of accepting program via analog balanced left+right, AES-EBU, composite, MPX over AES, Shoutcast/Icecast and local backup from a USB flash drive. Transmitter shall have a programmable hierarchy where a succession of alternate sources is selected automatically should the primary link fail. - A graphical user interface for control and telemetry shall be provided for both local and remote access. Operating constants shall be displayed graphically and numerically, including but not limited to PA voltages, currents, forward and reflected power, internal temperature of power devices, fan speeds, and exciter parameters. Locally, a 17” (minimum) touchscreen shall be installed in the front of the transmitter, with access to all functions. An IP addressable Ethernet port shall also be active at all times, for use with LAN/WAN and internet access. In addition, a conventional GPIO interface with DC sample voltages and responding to external contact closures shall be included to accommodate traditional remote control equipment. Both graphical and GPIO access shall be active and not mutually exclusive. Preferred model: Nautel GV15D, with second exciter with Exgine card, and Exciter/Controller UPS option, or approved equal.
