We take the SEARCH out of Search and Rescue Page 1 of 12 AU10 FCC Waiver Applicant: Marine Rescue Technologies Ltd Correspondence Reference Number: 45776 Form 731 Confirmation Number: EA596693 Further to your questions 1 &2) below and a request for additional clarification: 1) The waiver exhibit (WT Docket No. 13-99) states that MRT has been granted a waiver to upgrade the device to transmit identify and location information on the international AIS channels at 500mW ERP. It is thus understood that the EUT will radiate no more than 500mW ERP. Other power parameters listed in this application include a conducted output power of 1W, an air band power of 100mW ERP, and a marine band power of 1W EIRP (latter two values from the user manual exhibit). Although it is known that conducted output, ERP, and EIRP values will be different depending upon antenna gain and other system parameters, the large deviation in values requires additional clarification. Furthermore, please elaborate on the difference between the two mentioned ERP values (100mW v. 500mW). i) Overview: The EUT radiates close to 500 mW and it’s conducted output power when measured directly is similarly just under 500 mW. The antenna is a whip with it’s coaxial feed acting as counterpoise. This combination gives a high antenna gain. During testing to RTCM 11901.1:2012 the antenna gain was determined as 2.69 dBi @ 162 MHz. This accounts for the considerable difference between the ERP and EIRP radiated figures. The transmitter output power is reduced for 121.5 MHz transmissions by internal firmware and the corresponding slight reduction in antenna gain at 121.5 MHz means that the AU10 ERP radiated power never exceeds 100 mW. ii) AIS Conducted: The requirements of RTCM 11901.1:2012 clause E.7.2.1.3 means that the antenna gain is added to the conducted measurements and in all cases the AU10 passes the minimum requirement of 27 dBm (500 mW). The corrected values recorded were between 28.062 dBm and 30.007 dBm under all conditions. These values are closer to 1W and this is why the documentation uses 1W as the nominal figure. iii) AIS Radiated: The AU10 radiates no more than 500 mW ERP when tested using ETSI dipole substitution method employed in all ETSI standards. However when tested using the very different method employed by RTCM 11901.1:2012 clause E.7.3 the value recorded was 29.55 dBi (901.36 mW EIRP). Again this is closer to 1W and this is why the documentation uses 1W as the nominal figure. iv) 121.5 MHz Conducted: The AU10’s conducted output power measured at the RF output terminals and without any corrected factors applied falls between 80 and 120 mW. Furthermore this particular test is applied at the factory to all production units. 100mW is stated as the nominal conducted output power. v) 121.5 MHz Radiated: The AU10 antenna gain at this frequency falls slightly and therefore the radiated power measurements made using the dipole substitution method never exceed 100mW ERP.
