BFR92A Q6.................RF NPN......................Nec. 46134 Q7,Q8,Q9,Q10.......AUDIO NPN...................Mot. 2N5088 RF Circuit Discription: The Microcontroller (U4) has 2 factory programmed frequencies 154 - 174 Mhz. The clock frequency of the microcontroller is 4 Mhz. The microcontroller sends data to the Phase Lock (U3), which converts the data into a dc voltage. This voltage is applied to the varactor which moves the oscillator (Q4) frequency to programmed frequency. The oscillator output is injected into the buffer (Q3), the buffered output is fedback to the PLL (U2) and the RF pre-amp (Q5). When the oscillator is at the desired frequency the PLL lock detect output turns ON the N-Channel FET (Q1) which turns on the PNP transistor (Q2) and applies voltage to the pre-amp and the final amp (Q6). The harmonic output of (Q6) is attenuated by the low pass filter. Audio Circuit Description: The microphone signal is amplified by (Q9 and Q10). The pre- emphasis is handled by the RC combinations of both audio amplifiers. The low pass filter (Q7) attenuates the audio frequencies after 2700 Hz. THhe audio from the low pass filter is converted to a dc voltage, this voltage turns ON the AGC transistor (Q8) which shorts the audio from the microphone to ground to prevent over deviation. The varable resistor controls the amount of deviation to the varactor. Antenna/Microphone Description: The antenna and the microphone are combined together through a matching circuit. The 1.8 uh inductors isolates the RF from the audio section. The 100 ohm resistor and 18 pf capacitor matches the transmitter low pass filter to the antenna. Computer interface Description: The microcontroller has a 2 wire interface with the computer. When the program cable is connected to the transismitter and the computer this disables the transmitter and puts the microcontroller in program mode. The data from the computer is converted in a hex number and stored in EE of the microcontroller.

TUNING PROCEDURES FOR THE CST-2001/V The factory has programmed f1 to 154.0000 MHz and f2 to 174.0000 MHz. 1. Apply power to the transmitter 6.0 Vdc 2. Connect a coax cable to the 50 ohm test point, and place a 30 Dbm pad in series with a spectrum analyzer. 3. Turn the transmitter ON in the f2 channel position, monitor the supply current. 4. Measure the voltage at the junction of R12 and R13, by compressing the oscillator coil (L2) adjust the voltage to 3.25 volts. 5. Monitor the frequency of the transmitter with a frequency counter. The frequency should be 174.000000 MHz. Adjust the reference (X2) to the above frequency +/- 100 hz. 6. Monitor the power output with a watt meter (power output should be 250 mw +/- 1 Dbm.) @ 130 ma. 7. Adjust C34 while in f2 to reduce the second harmonic of the transmitter to 55 dbc maintaining 250 mw. 8. Slide the switch to f1 the frequency should read 154.000000 MHz +/- 100 Hz. The voltage at the junction of R12 and R13 should be 1.2 volts. Monitor the second harmonic with the spectrum analyzer, the second harmonic should be > 44 Dbc. 9.
