- Description
- Amendment 4 is hereby issued for the following reasons: To provide a response to the questions listed below. The Government's response/answer is provided after each question. 1) In the technical requirements, keypad entry of a DSC Test Message is cited. We are requesting a clarification or more specific definition of this requirement, or an example of the "test message". Government Response: The test message is the standard DSC Test Call, per ITU 493. 2) In the technical requirements, several audio interfaces for remotes, microphones, VDR are specified. We would appreciate further clarification regarding these audio interfaces. At a minimum, a) Which or how many of these audio interfaces need to be active on a simultaneous basis? Government Response: All the interfaces need to be active simultaneously. The VDR interface needs to continuously recording both the transmit and receive audio, at all times. The interface to the remote stations need to fully functional at all times. If used, the interface to the crew communications system needs to be operational at all times. b) Does the USCG desire or require Squelch Adjustment to be applied to the VDR line? Government Response: Squelch is not required on the VDR line. 3) Regarding Class A specific deliverables and ?per unit" pricing; a) Are ALL Class A VHF units to be delivered with a 120VAC power supply? Government Response: If the unit uses a external power supply for 120 VAC, recommend that the 120VAC power supply be priced separately. b) Are ALL Remote units to be delivered with a 120VAC power supply? Government Response: If the unit uses a external power supply for 120 VAC, recommend that the 120VAC power supply be priced separately. c) Will ALL Remote units require a 175 foot cable with connectors to be supplied? Government Response: No, this is the worst case situation; other installation will require a shorter cable. d) ) Is there an estimate of the quantity requirement for Remote Class A units versus Primary Radios ? Government Response: The Coast Guard desires that there be one radio Class A radio. The Class A radio shall have the capability of using a minimum of one or no remote station. 4) Regarding Class D specific deliverables and "per unit pricing"; a) Will ALL Class D radio installations require Remote units? Government Response: Per requirement number 7 of the Class D radio requires a remote capability b) Will ALL Remote units require a 175 foot cable with connectors to be supplied? Government Response: No, minimum cable length is specified for the Class D radio. A minimum length of 30 feet is desired. c) Is there an estimate of the quantity requirement for Remote Class D units versus Primary Radios? Government Response: The Coast Guard desires that there be one radio Class D radio. The Class D radio shall have the capability of using a minimum of one or no remote station. 5) The USCG specifies that the Class A will have simultaneous Channel 70 DSC receive capability, indicating a requirement for two antenna ports. Yet, the Class D requirement does not specify the same level of simultaneous Receive requirement. a) The question is that since both Class A and Class D require two receivers of which one is dedicated to channel 70 DSC, and the general vision of Class D installations being for smaller vessels, does the USCG require a Single antenna port for Class D? Government Response: Yes b) Alternately, will the USCG accept two antenna ports on Class D radios? Government Response: A single antenna is desired on the Class D radio. 6) In attachment II, item J, the USCG discusses Waterproof Remote Speakers and Remote microphones. a) Is there an estimated quantity of Remote speakers that are required with Class A and Class D radios? Government Response: Each radio with a remote station will require a remote speaker and microphone. Note that the remote speaker may be integral to the remote station. 7) Regarding IEC 529, level 4 waterproof requirements, will the USCG accept external waterproof covers? Government Response: Covers may be used, provided that they do not impede operations of the unit and that the unit can withstand the IPx4 level of exposure per IEC 529. As a result of the above, the closing date is hereby modified to 10 August 2007 at 1700 (5:00 PM)in lieu of 09 August 2007 at 1400 (2:00 PM).
