58 -- MARKET SURVEY FOR EXISTING NON-DEVELOPMENTAL AN/PRC-126 RADIO SET EQUIVALENTS POC Mr. Daniel Schwartz, Project Engineer, (908) 532-3702/5211. This is a Market Survey to obtain a Rough Order of Magnitude for Price and Avaliability Data for existing AN/PRC-126 Radio Set (NSN: 5820-01-215-6181) equivalents. The AN/PRC-126 has been manufactured in the past by Magnavox Electronics Systems Company. As a minimum, the equivalent radio shall meet the following technical characteristics: The radio shall cover the frequency range of 30 - 87.975 MHz. Channel spacing shall be a minimum of 25 KHz. With regard to the Occupied Bandwidth, 99 percent of the transmitted spectrum energy shall be contained in less than 25 KHz. There shall be two communication ranges, a short and a long range (each using seperate antennas) of 500 and 3,000 meters, respectively. A single antenna is acceptable, provided that it meets the 3 Km range requirement and meets the size requirement for the short antenna. The short antenna shall not exceed 16 inches and the long antenna shall not exceed 4 feet. Telescoping, collapsible, and or rigid antennas may not be acceptable. Both ranges shall provide for reliable commuinications over rolling, slightly wooded terrain. The radio must be interoperable with the AN/VRC-12, AN/PRC-77 and SINCGARS Family of Radios operating in the single channel non-secured mode. The radio must transmit a squelch tone of 150+/-2 Hz. The radio must utilize either a 150 Hz tone squelch or a noise squelch for receive. A minimum of 10 presets randomly selectable across the entire frequency range is required. These presets must be externally selectable, and be programmable by the operator without any internal alignments or external fill devices. Access to these preset programming controls must not require opening of the entire radio case and the environmental integrity of the radio must be maintained. Turning the radio off and/or replacing the battery shall not erase the preset memory. The radio with battery, excluding antenna, shall be no larger than 60 cu. in. The radio shall weigh no more than 57 oz., including battery and long antenna. The battery shall be of a commonly available throw-away type and shall be easily replaceable by the operator. If a magnesium or lithium battery is used, adequate safeguards must be utilized to preclude pressure build-ups. The battery shall be able to provide 24 hours of continuous operation with a standby to receive to transmit ratio of 8:1:1: duty cycle at a temperature of 78 degrees fahrenheit. At the end of operation, the transmit power out shall not degrade by more than 6 db below the original transmit power out. The volume control shall be set at a normal volume control position to allow clear and audible communications through the internal speaker and a 1+/-5 percent KHz tone signal shall be used for receive and transmit. The radio shall be supplied with a carrying bag which is capable of being affixed to the individual equipment belt and individual equipment belt suspenders. The radio must be operational in the carrying bag and all operational controls must be easily accessible to the operator. The radio shall be provided with a lightable electronic means of displaying the operating frequency. The radio shall operate such that the detectability of any light sources (including the frequency display), by Generation III image intensifer night vision devices, is minimized to the maximum extent possible. The radio must have an internal microphone/speaker with a push-to-talk capability and a hands free monitor capability. An external handset connector shall be provided. A volume control shall be provided that shall allow the operator to adjust the audio output of the radio to complete silence. Connection of the handset shall mute the audio output of the radio's internal speaker. The radio shall have easily accessible, identifiable, understandable and useable operator controls which will allow for complete specified operational performance. The use of external devices or test equipment by the operator to set, select, adjust or align the radio to achieve the specified operational performance is not permissible. No radioactive materials shall be used in the radio or in ancillary equipment. The radio shall operate without degradation in specified performance at ambient air temperature as high as +55 degrees C and as low as -40 degrees C. The radio shall withstand exposure to ambient air temperature as high as +71 degrees C and as low as -57 degrees C. Environmental test data addressing areas such as humidity, altitude, vibration, drop, immersion, fungus, salt/fog and sand & dust is strongly encouraged. Test Data pertaining to Electromagnetic Intereference is also strongly encouraged. All spare repair parts (lowest replaceable units) shall be identified. Markings of all operator controls, radio functions, radio accessories and maintenance parts shall be in easily understandable and readable user terminology. The radio shall be finished in accordance with the requirement for Chemical Agent Resistant Coating per MIL-C-46168. The radio shall have a specified upper test Mean Time Between Failure of at least 2,000 hours over the specified environmental operating range, excluding normal battery life. Interested suppliers may submit a Rough Order of Magnitude for price and availibility data in writing to the POC delineated herein. If possible, price data should be provided in quantity dependent ranges such as price per radio if order quantity is 500 radios or less, 501-1000, 1001 and higher, etc. The deadline for submissions is no later than 20 days after the date of publication for this survey. All submissions are to be sent to US Army CECOM, ATTN: AMSEL-LC-ED-RR(Mr. D. Schwartz), Fort Monmouth, New Jersey 07703-5023, 908/532-3702/5211. (0134)
