TM 55-1945-205-24-40002 00 40002 00The transmitter has a conducted spurious emissions of 65 dB (high) and 55 dB (low). The audio response is within +2/-8 of 6 dB/octave pre-emphasis characteristic from 300 Hz to 3000 Hz. The AF harmonic distortion of the transmitter is 3%. The transmitter has a hum and noise rating of 37 dB and a frequency stability (-20 Deg. to +50 Deg. C) of + 0.0005%.The receiver has a sensitivity rating of 20 dB quieting at 0.35 uv and 12 dB SINAD at 0.30 uv. The squelch sensitivity (threshold) is 0.20 uv. Modulation acceptance bandwidth is + 4.5 kHz. Receiver selectivity: spurious and image rejection 60 dB, inter modulation regulation 60 dB and channel spacing 25 kHz selectivity. DECK MATTINGThe deck matting is used as dunnage and is placed where the cargo ramps of the sealift vessel and the lighters will land on the FC deck. The individual mats are a high density polyethylene material and are approximately 10 ft long by 4 ft wide and 1½ in. thick. Each mat weighs 300 lbs.DECK CLEAT AND D-RING/CLOVER LEAF FITTINGSThe modular sections are provided with deck fittings to meet various operational needs. These fittings have a 15,000 lbs load capacity and are inserted into the tube turns. There are ten tube turns per non-powered module and five per end rake.MOORING BITTThe mooring bitts provide securing points on the trident pierhead for lighters and for fenders. They attach to the platform at the module connector locks. The bitts are designed for up to a 6 in. circumference mooring line. The mooring bitts are lifted and installed using the forklift adapter. Each bitt weighs 235 lbs and is 6 ft 5 in. long. Eight mooring bitts are provided with the FC system.FENDERS (WITH ATTACHMENT CHAINS)Three sizes of tubular-shaped fenders are components of the FC. The 4 ft X 12 ft fender weighs approximately 1450 lbs. The 3 ft X 5 ft fender weighs approximately 300 lbs. The 5 ft X 10 ft fender weighs approximately 1500 lbs. FLOATING CAUSEWAY ANCHOR MOORING SYSTEM (FCAMS)The FCAMS is designed to hold the floating causeway during Logistics Over The Shore (LOTS) operations in sea conditions up to Sea State 3. The offshore mooring leg is designed to perform in soft soils and sand. The onshore mooring leg is designed to perform in soft soils, sand and competent rock.In addition to Sea State, the capability of the FCAMS to hold the floating causeway in position is highly dependent on the alongshore current speed and number and type of vessels mooring to the floating causeway. It is also dependent on the water depth at the vessel’s location. The complete system, which has 16 offshore mooring legs and four onshore mooring legs, is required for a full floating causeway that is 1500 ft long. The following table shows the estimated current speeds for the FCAMS to hold the floating causeway in place when one or two lighters are moored alongside the five string wide trident pierhead extension of the floating causeway.
