The product is a GPS pet containment base reference station that collects ephemeris data and computes pseudo range corrections and relays these to GPS mobile units via 151.82 MHz. The product also indicates base station and GPS mobile unit status. Rated Maximum Output Power: 16.2 dBm Measured Conducted Output Power: 15.7 dBm Modulation type: GFSK Data Rate: 3600 bps Frequency Deviation: 1482 Hz 1.2 Related Submittal(s)/Grant(s) The EUT is subject to the following authorizations: a) Certification as a 151.82 MHz, MURS transmitter per FCC Part 2, Subpart J and Part 95, Subpart J, MURS and Subpart E, Technical Requirements. b) Verification under 15.101 as a digital device and receiver. 1.3 Test Methodology These measurements were conducted in accordance with the requirements of Title 47 CFR Part 95, Subpart E and TIA-603-C (2004). All measurements are in terms of peak values unless stated otherwise. The measurement system video bandwidth was set to at least three times that of the resolution bandwidth to prevent the introduction of amplitude smoothing throughout the evaluation process. If interconnecting cables are part of the measurement setup then they were manipulated as necessary to maximize emissions. A block diagram of the tested system is shown in Figure 1. Page 5 of 19

The RF port where the antenna is terminated was connected to a short RF cable and attenuator. The SMA connector was directly connected to a spectrum analyzer. The EUT was set up to transmit a signal with >98% duty cycle. The receiver and video bandwidth on the spectrum analyzer was maximized and the span was sufficiently large enough to capture the peak emissions. The spectrum analyzer’s scale was adjusted to account for any cable loss and the attenuator. The peak measurement of the signal was recorded. 2.1.1 Maximum Power Allowed The maximum power allowed is 2 Watts (or 33 dBm) per FCC 95.639(h). 2.1.2 Measured Fundamental Signal The maximum output power of the EUT as measured below is .0367 W. 15.65 dBm into 50 ohm measurement system = 36.7 mW <<2 Watts Antenna gain = -1 dBi EIRP = 15.65 – 1 = 14.65 dBm = 0.0292 W << 2 Watts The EUT was determined to comply with the Maximum Allowed Power.

The Bandwidth of the Fundamental was measured using a spectrum analyzer, as shown below. A RBW that was > 1% of the authorized bandwidth was used to measure the EUT’s bandwidth. Using the Emission Bandwidth measurement technique of ANSI C63.10-2009 as a guide, the measurement of the Emission Bandwidth is found to be 6.944 kHz. Page 12 of 19

The EUT was found to comply with the Maximum Authorized Bandwidth since 6.944 kHz < 11.25 kHz. Figure 3.

US Tech Test Report: FCC Part 95 Report Number: 15-0116 Issue Date: May 5, 2015 Customer: Radio Systems Corporation Model: 300-3048 FCC ID: KE3-3003048 4 Unwanted Radiation Emissions (CFR 95.635 (e)) This requirement is from 47 CFR Part 2, Subpart J, Sections 1053 and 95.635(e). The power of each unwanted emission shall be less than TP (Transmitter Power) as specified in paragraph 5.2 below. 4.1 Test Method These emissions were measured on the Spectrum Analyzer via a short RF cable soldered to the RF output port of the transmitter circuit board. 4.2 FCC Limits Per CFR Part 95.635(e) transmitters designed to operate in the MURS band shall comply with “Emission Mask 1 : For transmitters designed to operate with a 12.5 kHz channel bandwidth, any emission must be attenuated below the power (P) of the highest emission contained within the authorized bandwidth as follows: “(i) On any frequency from the center of the authorized bandwidth f o to 5.625 kHz removed from fo: Zero dB. (ii) On any frequency removed from the center of the authorized bandwidth by a displacement frequency (fd in kHz) of more than 5.625 kHz but no more than 12.5 kHz: at least 7.27(fd −2.88 kHz) dB. (iii) On any frequency removed from the center of the authorized bandwidth by a displacement frequency (fd in kHz) of more than 12.5 kHz: at least 50 + 10 log (P) dB or 70 dB, whichever is the lesser attenuation.” Page 14 of 19

The measured emissions comply with the specified mask as shown below. Figure 4.

The EUT was tested in the far field. Measurements for 30 to 1000 MHz were made with the analyzer's bandwidth set to 120 kHz. Measurements above 1000 MHz were made with analyzer’s bandwidth set to 1 MHz and 3 MHz. Since the EUT is part of a portable handheld configuration, the EUT was rotated through the three orthogonal planes to produce the highest emissions relative to the limits. Results are shown in the Table below. 5.2 FCC Limits The limit is determined using the following information: On any frequency removed from the center of the authorized bandwidth by a displacement frequency (f d in kHz) of more than 12.5 kHz, the limit will be at least 50 + 10 log (P) dB or 70 dB, whichever is the lesser attenuation. Measured Conducted Output Power= 0.0367 Watts = 15.65 dBm Attenuation Calculation = 50 + 10Log(0.0316) = 35.65 Power Limit = 15.65 dBm – 35.65 dB = -20 dBm Page 16 of 19

The humidity was tested to a relative value of no more than 50%. The temperature was varied between - 30°C to +50°C in 10° increments. All measurements were referenced back to the frequency measured at +20°C. At each set point the temperature was allowed to stabilize for no less than 30 minutes before measurements were recorded and the temperature changed. The battery for the EUT was removed and the EUT was powered with a variable DC power supply. The voltage was varied between the nominal operating voltage 85 % of the nominal value and 115 % of the nominal value. The fundamental frequency for each voltage setting was compared to the nominal voltage ambient temperature measurement and reported as compared to the limit. 6.2 FCC Limits MURS transmitters must maintain a frequency stability of 5.0 ppm, or 2.0 ppm if designed to operate with a 6.25 kHz bandwidth. Since this EUT was measured to have a bandwidth of 6.94 the limit applied was 5.0 ppm. Page 18 of 19
