FEDERAL COMMUNICATIONS COMMISSION Racom s r.o. Authorization & Evaluation Division Mírová 1283 7435 Oakland Mills Road Nové Město na Moravě Columbia, MD 21046 592 31 U.S.A. Czech Republic Subject: FCC ID: SQT-RIPEX2-1A Dear Sir/Madam, The attached documents constitute a formal submission and application for Equipment authorization for the RipEX2-1A radiomodem pursuant to the FCC Part 90 rules. The RipEX2-1A device contains software to allow communication within the below mentioned frequency bands (MHz). 150.800 – 156.2475 157.1875 – 161.575 161.7750 – 161.9625 162.0375 – 170.000 Programming of transmit frequencies can only be performed by the manufacturer or by authorized service or maintenance personnel. Operator cannot directly program the transmit frequencies using the normally accessible external controls. There is no field tune-up procedure. All adjustments are software controlled and are pre-set at the factory and can only be changed by the manufacturer or by authorized service or maintenance personnel. We, RACOM s r.o. are aware of the FCC rules and that is a violation of rules for the device to operate on unauthorized frequencies. This device is designed to operate in 6.25, 12.5, 25 kHz channel spacings under Part 90 rules. This equipment is capable of supporting a minimum data rate of 4800 bits per second per 6.25 kHz of channel bandwidth. This letter serves as supplementary evidence and attestation for the frequency banding authorization application. If you have any queries, please do not hesitate to contact Racom s r.o.

Page 1 of 4 Maximum Permissible Exposure (MPE) Evaluation according to the OET Bulletin 65 (Edition 97-01) Evaluated equipment: The RipEX2 radio modem for data transmission in the 135 – 175 MHz frequency range Developed: Ing. Michal Voráček Date: 28.1.2021 Pages: 4 Page 2 of 4 Evaluated equipment The RipEX2 radio modem is designed for bi-directional data transfer in a radio frequency channel assigned from the specified frequency range. When transmitting, it generates an angle modulated, continuous, constant-envelope radio-frequency signal on the output (antenna) connector. The transmitted signal spectral width is limited to a single channel and never exceeds the respective channel spacing, which is 300 or 250 or 200 or 150 or 100 or 50 or 25 kHz or 12,5 kHz or 6,25 kHz. The maximum nominal output radio-frequency (RF) power of the RipEX2 radio modem is 10 Watts. The output RF power variation in extreme conditions is guaranteed by the manufacturer to stay within -3,0 dB to +2.0 dB limits. The RipEX2 radio modem main specifications for a frequency range around 160 MHz are in Table 1. Table 1 – RipEX2 radio modem main technical parameters Parameter Value Frequency range from 135 MHz to 175 MHz Channel spacing 6,25 / 12,5 / 25 / 50 / 100 / 150 /200 / 250 / 300 kHz Channel setting method software Supply voltage (nominal) 13,8 V Supply voltage range 10 V to 30 V Operating temperature range -40 °C to +70 °C Current consumption: Reception: Transmission 1W: Transmission 10W: 580 mA 1,1 A 3,6 A Configurable RF output power range from 0,1 W to 10 W Antenna connector TNC RF output impedance 50 ohm The RipEX2 radio modem is connected to the antenna by a coaxial cable. Since the antenna may be connected by a very short cable, the cable loss shall be considered negligible in the calculation. The main parameters of recommended antennas are listed in Table 2. These are parameters specified by the respective manufacturers. The antennas listed in Table 2 are supplied with the RipEX2 radio modem upon request. Page 3 of 4 MPE Calculations According to the OET Bulletin 65 (Edition 97-01) R= √ P.G 4.π.S Where: S=Power density (in appropriate units, e.g. mW/cm2) P=Power input to antenna (in appropriate units, e.g., mW) G=Power gain of the antenna in the direction of interest relative to an isotropic radiator R=Distance to the centre of radiation of the antenna (appropriate units, e.g., cm) Tx Frequency = 160 MHz The exposure at the lowest frequency of the operating range make the worst case, since the limits given in §1.1310 of the FCC Rules increase with frequency (in the frequency range applicable to the evaluated equipment) whereas the radiation from RipEX2 radio modem will be constant. Maximum peak power = 42.0 (dBm) The maximum peak power is calculated as the nominal maximum power increased by the margin allowed by the applicable FCC standard (+2dB) Antenna gain = 2.15 (dBi) The antenna gain of the half-wave dipole is considered as the worst-case scenario. The areas of exposure never lie in the direction of the main lobe of the transmitting antenna. In fact, the higher the gain of the antenna is, the lower the radiation in the directions relevant for exposure evaluation will be. S = 368/1500 = 0.245 [mW/cm2] The FCC limit for exposure of general population / uncontrolled exposure at 160 MHz Page 4 of 4 P = 15850 [mW] The numerical value of maximum TX power G = 1.64 The numerical value of half-wave dipole gain The worst case scenario also assumes 100% duty cycle. Though the equipment assessed allows for that, it never happens in reality thanks to the packet-oriented transmission environment. Calculated minimum separation distance from antenna, where the limit for general public / uncontrolled exposure is met, is: Ru = 92 cm The distance, where the limit for occupation / controlled exposure is met, is: Rc = 41 cm The distance, where the limits are met for typical directional and omni directional antennas typically used with RipEX2 radio modem. For directional antennas is safe distance validate in direction side of main beam, where is maximum energy emitted by antenna. 135 - 175 MHz/ 2m band - 10 Watt RF power Antenna code Antenna description Gain G (dBi) Gain G (-) Distance where the FCC limits is met for General Population/Uncontrolled Exposure (cm) Occupational/Controlled Exposure (cm) OV138.1 single dipole 4.6 2.9 152.1 53.1 OV138.2 stacked double dipole 7.6 5.8 214.8 75.0 SA138.3 3 elemet directional Yagi 8 6.3 225.0 78.5 SA138.5 5 elemet directional Yagi 10 10.0 283.2 98.8 Table #1 – The distance where the FCC limits are met for typical antennas Conclusion: It is safe to assume that members of general public will never be present in the distance Ru (or lower) to a fixed installation of antenna of the evaluated equipment. Equally it is safe to assume that e.g. a member of staff performing mast maintenance will spend only negligible fractions of time in the Rc (or lower) distance to the transmitting antenna (the Rc distance actually corresponds with the physical size of the antenna itself). Consequently, in our opinion, the operation of the evaluated equipment would not make a significant environmental effect.
