FCC ID: PV6LF-DISHTX Circuit Description The 444MHz transistor oscillator drives the base of Q2 the final/buffer amplifier. The modulation provided by IR controller. The output of Q2 has the matching network consisting of C6 and C3 that limit the harmonic content and effect the proper coupling of the antenna to the output stage. Antenna, Ground and Power Source There is no external antenna, antenna build in on PCB. There is no external ground connection. The ground is only that of the printed circuit board. Electric current is supplied by a 12Volt (“A23”) primary storage cell.

Measurements in both horizontal and vertical polarities were performed. During the test, each emission was maximized by: having the EUT continuously working, investigate all operating modes, rotated about all 3 axis (X, Y & Z) to obtain worst position, manipulating interconnecting cables, rotating turntable, varying antenna height from 1m to 4m in both horizontal and vertical polarizations. The emissions worst-case are shown in Test Results of the following pages. *:OATS [Open Area Test Site] located at HKSTC with a metal ground plane on filed with the FCC pursuant to section 2.948 of the FCC rules, with Registration Number: 90657.
