The radio’s 50Ω, BNC antenna was connected to the 50Ω input of the Hewlett-Packard Model 8560E Spectrum Analyzer used to measure receiver spurious emissions. Power was supplied to the LM-U450 through P504. The supply voltage was set at +12 VDC, the nominal input voltage. 2. The Hewlett-Packard Model 8560E Spectrum Analyzer was set for: • 100 kHz resolution bandwidth • 100 Hz video bandwidth • 10 MHz span 3. The spectrum was searched: from 14.4 MHz, the VCO reference oscillator to 1250 MHz, the 3 rd harmonic of the receiver 1 st local oscillator 4. Spurious emissions were recorded on the following table. 5. Steps 1, 2, 3 and 4 were repeated at 450.050 MHz and 470.050 MHz, the receiver band edges.

Measurements were made in accordance with FCC Rules & Regulations Part 2.947, using the procedures of IEC Publication 106. 1. The LM-U450 was programmed to receive on 460.050 MHz, the middle of the operating band. 2. An AFB-1545 antenna that is included with each LM-U450 was installed at the antenna port. 3. All field strength measurements were made with the Hewlett-Packard Model 8560E Spectrum Analyzer and the appropriate antenna for the frequency being measured. Antennas used were: • Electro-Metrics BDA-25 Dipole Antenna at 0 to 200 MHz • Electro-Metrics LP-25 Log Periodic Antenna at 200 to 1000 MHz 4. For each emission, the height and polarization of the field strength measuring antenna and orientation of the LM-U450 were varied to provide maximum field strength. 5. The spectrum was searched from 30 MHz up to the 2nd harmonic of the receiver 1 st local oscillator per FCC Part 15.33(b)(3). 6. The LM-U450 was then programmed to receive at the band edges (450.050 MHz and 470.050 MHz) and test measurements were repeated as described above. RESULTS: For all 3 test frequencies, all emissions were better than the noise of the spectrum analyzer at -109 dBm. This translates to a field strength < 8 μV/m at 3 meters for the antennas used.
