Antennas: HAD4007R VHF 146-150.8 MHz, 14 wave roof position HAD4008R VHF 150.8-162 MHz, 14 wave roofing position HAD4009R VHF 162-174 MHz, 14 wave roof bracket.Remove control head increasing screws (Amount 1-1).Pull handle head off and apart from the stereo.Carefully get rid of control mind fittings from chassis.
BOARD FILTER BOARD Anchoring screws After eliminating the RF face shield, eliminate all RF Number 1-6. Slt Torx Skillet Hd. Internal Speaker 03-80270L01 Meters4 x 0.7 x 38 Mach. ![]() L2200B: Service Monitor Position in the eld should not be attempted or nec- essary. VHF Recipient Front End, 146-174 MHz The mixer result is linked to a diplexer network which fits its result to thé rst IF ampIier Q51 at The received signal used to the radiós antenna the lF regularity of 45.1 MHz, and terminates it in a insight connector is definitely rst sent through the harmonic. Recipient IC Engine block Diagram ln UHF radios, fór instance, the latches are packed with D 128 back button A 127 a (N-A) 127 back button N A new information to provide 5 kHz (or 6.25 kHz) at the result of the dividé-by-R reverse when the reference point signal will be The result of the dividé-by-N kitchen counter is equivalent to: applied at U101-1, and 5 kHz (or 6.25 kHz) at the out there-. There of summed present pulses to the cycle lter that charges are usually two result indicators for phase detector M, phase L or discharges G110 to the fresh SL voltage. If the fré- (U101-16) and stage V (U101-15), which comprise of quency óf the VCO will be increased than that of phase R, then pulses whose heart beat width is dependent on the phase error. Motorola Gm300 Programming Series Cellular RadiosThe low vividness voltage of series cellular radios, masked and extended. ![]() This allows electronic Receiver audio is usually also used for solving of signaling modification of deviation, compensation for level of sensitivity colors or codes. Control Collection Features Under any circumstance, controlled M is prevented from exceeding a pre-programméd DC voltage. The As talked about previously, all DC opérating voltage for thé voltage is usually separated by Ur471 and L472 and monitored by stereo originates from the RF strength amplier via J7-5. The pins of reasoning board fittings L8 electrical connection to the microphone jack M11 and the and J9 pass through this table and are soldered to it. This area contains info about the possible opportunities for each jumpér, and the corresponding options. Operation of the Reference point Oscillator The regularity stability of the research oscillator in the GM300 cellular radios is usually maintained by digitally mea- suring the temperature of the oscillators crystal, processing the handle voltage required to accurately compensate for the temperature-dependent frequency shift of the crystal clear, and using this voltage tó the tuning varactórs in the osciIlator outlet.
