Then remove the XLR housings by pulling them to the rear. 3-1 TRANSMIT BOARD CIRCUIT DESCRIPTION ALIGNMENT PROCEDURE U50IC is an amplifier whose gain is controlled by the level of audio entering the rectifier at pin 16. As the level here increases, the gain is decreased and this results in a 2:1 compression characteristic. Pre-emphasis is added by U501B. R504, R505, and C508 set this at 115uS. C531 rolls the response off above 10KHz to further attenuate the 20 KHz call signal (see Audio Board Circuit Description). Q501 is a Colpitts oscillator with the collector tuned to the third harmonic. T501, VVC501 and VVC502 are added in selies with the crystal to allow frequency modulation of the oscillator. The oscillator is operated 10KHz below the series resonant point of the crystal. This improves linearity at the expense of some stability. Q502 is a trip1er and Q503 is a straight through amplifier. The catTier frequency is thus nine times the crystal. C529, C530 and L503 function as a low pass filter and matching network. EQUIPMENT REQUIRED: o o o RF POWER METER FREQUENCY COUNTER DC VOLTMETER 1. Connect the RF power meter and frequency counter to the Transmit Antenna jack. Make sure the Transmit switch on the reat· panel is set the the Cont position. 2. Adjust T502, T503, T504, VC501, and VC502 for maximum power. Note: If adjustments are severly out of alignment and no output can be obtained, it may be necessmy to first adjust T502 and T503 for maximum DC voltage at the emitter of Q502. Then adjust T504 for maximum DC voltage at the emitter of Q503. Now adjust VC50 1 and VC502 for maximum power. 3. Adjust T501 for the COlTeCt frequency: Y501 Marking Frequency 154T570 154.570 177T800 177.800 183T730 183.730 4. Repeat Steps 2 and 3 as necessmy. 5. Deviation will be adjusted in the audio board alignment. 3-2 Voltage Tables - Transmit Board (878521) DEVICE 1====-r===r===r====jPI=N=N=U=rM=B=E"F'R==~===r==~==l1 .--18 17 16 15 14 13 12 11 20 19 U501 5 2.5 2.5 2.5 2.5 1 2.5 2.5 2.5 ---, 2.5 U501 0 2.5 1 2 3 4 5 7 6 8 9 10 PIN NUMBER Q501, Q502 o DEVICE E B C Q50l 1.88 2.44 10 Q502 0.78 0.66 9.7 Q503 1.21 0.26 9.5 C B E ) 3-3 Q503 C E B Figure 9 Transmit Board Component Layout (Foil Side) C501 o0 + I R502 -e::>- R501 +~04 V a O c:::> R504 C507 C5<t9,.-t U ylQ OC506 R51 6 l'l Y C525 aY l'l RS20 U502 CS11 I()C512QQ lQ + C522 a R517 ~ OS03 ~@C501 N ::!

Signals entering the board proceed through 3 tuned circuits, Q301, and three more tuned circuits to the mixer. HY301 is a doubly balanced diode mixer and receives +7 dBm from the oscillator. Q302 is a Colpitts oscillator with the collector tuned to the second harmonic on version 1 boards and the third harmonic on version 2. Y301 operates on the fifth overtone with C311 and L308 acting as mode suppressor. L307 is used to set the oscillator on frequency. From the mixer the signal continues through Q303 to filtet drivers Q320, Q370, Q420 and Q470. On version 1 boards the signal is resistively coupled to the filters. On version 2 boards it is inductively coupled. The four I.F. strips are the same except for component values. For the remainder of the description the parts in the 10.7 MHz I.F. will be referred to. U320A mixes the incoming signal with a 10.245 MHz oscillator to produce the second I.F. of 455 KHz. (The other three oscillators operate at 455 KHz above their n~spective input frequencies). U320B contains a limiter and quadrature detector, which is tuned by L322. U320C functions as a 94 KHz bandpass filter for operating the squelch. With. no signal a large amount of noise is present at U320 pin 13 and a portion of this is rectified by Q321. If the emitter rises above .7V U320D clamps pin 16 to ground, muting the audio, and drives pin 15 low, extinguishing the LED on the front panel via Q322. When a signal is received, the noise at U320 pin 13 drops and lowers the voltage at the emitter of Q321, releasing the audio clamp and lighting the front panel LED. Since the LED current flows through R33l, the voltage drop acts on Q32l and provides hysteresis. VR321 adjusts not only the noise amplitude delivered to Q321 but also the D.C. bias, and is used to set the squelch at 1 microvolt. From U320 the audio is buffered and filtered by U321. R328, C335, and VR320 set the de-emphasis at l15uS. U321Ais a three pole Butterworth low pass filter with a cutoff frequency of 10 KHz. CIRCUIT DESCRIPTION PCB 70714000 This unit is a four channel single conversion receiver consisting of one front end and four I.F. strips. Signals entering the board proceed through 3 tuned circuits, Q30l, and 3 more tuned circuits to the mixer. MX301 is a doubly balanced diode mixer and receives +7 dBm from the oscillator. Q302 is a Colpitts oscillator with the collector tuned to the second harmonic. Y301 operates on the fifth overtone with C319 and L308 acting as mode suppressor. L310 is used to set the oscillator on frequency. From the mixer the signal continues through a broadband filter to line driver Q303. VR309 is used to set the collector current to 20 rnA. Q303 drives the four I.F. strips, beginning with crystal filters FL30l-FL308. The four I.F. strips are the same except for component values. Also, the 10.7 MHz I.F. substitutes a ceramic filter for two tuned circuits. For the remainder of the description the parts in the 10.7 MHz I.F. will be referred to. The I.F. signal is amplified by Q304 and U301A, and limited and detected by U301B. U301B contains a quadrature detector which is tuned by T309. Squelch is of the amplitude type, the D.C. voltage at pin 5 of U301 varying in propOltion to the signal strength. With no signal U302 pin 1is low and the audio outputis squelched. When the received signal causes the voltage at pin 3 of U302 to exceed that of pin 2 of U302, pin 1 goes high and the squelch opens. VR30l sets the threshold at pin 2 and thus the squelch. R320 provides hysteresis. Q305 is used to drive the LED on the front panel. From U301 the audio is amplified by U303A. R389, R328 and C354 set the de-emphasis at 115uS. VR302 is used to compensate for variations in detector output level. U303B is a 3 pole ButterwOlth low pass filter with a cutoff frequency of 10KHz. 3-9 ALIGNMENT PROCEDURE Receive Board - 70714000 Equipment Required: D D D D 11.

Receive Expanders Audio from the receive board is routed through Jl08, Jl09, JllO and Jlll to U1l2 and U1l3. The gain ofthese devices is controlled by the audio level at the rectifier pins .(4 and' 16). As the level increases, so does the gain, and this results in a 2: 1 linear expander characteristic. This complements the processing done in the transmitter. The audio is then buffered and delivered to the remote select switches. C) Microphone Amplifier From the headset connector the microphone signal is amplified by U103. Depending upon which type of microphone is used, S102 is set by the user to dynamic or electret. The electret position provides an 11 dB drop in gain to compensate for the extra output. The amplifier is peak limiting, and responds to either positive or negative peaks exceeding about 1.1 volts in amplitude. Peak detectors Q106 and Q107 charge C120 and C121, driving QI05 toward pinchoff. This reduces the gain momentarily until the input signal is reduced. Visual indication of peak limiting is provided by D608 which is driven by U105 when the voltage at pin 6 exceeds half a volt. D111 (version 3 and later) /isolates the time constant of the amplifier from'that of the LED driver. The latter is much shorter than the former, and causes the LED to extinguish immediately upon removing the input signal. On versions 1 and 2 the LED will remain lit for several seconds. VR604 is adjusted by the user for maximum input with minimal limiting. QI04 is used to tum the microphone on and off and is driven by the push-to-talk latch circuit. When SIlO is pressed in and held, the state of Ul16B follows the switch and tums on Q110 and Q111 via D110. This lights D609 and gates on the microphone audio. Releasing S110 tums off the microphone. U116A does not change state under these conditions because C~82 is discharged when the clock is pulsed. If, however, S110 is depressed twice in quick succession, C 182 will be charged for the second clock pulse and this will set U116A. Now the microphone is latched on via D109 and will remain on until S110 is depressed once again, resetting U 116A. Auxiliary Input Amplifier Audio from JlOl is attenuated and converted from balanced to single-ended by U101A. U101B, UI02A, Q101, QI02 and QI03 form a peak limiting amplifier identical to that described for the microphone above. S101 not only enables the audio path for the auxiliary input but also lights D607 to half-brilliance to indicate active auxiliary. When peak limiting occurs U 105A shorts out R 120 and D607 is brought to full brilliance. Intercom Driver UI07A is configured as an AC current source whose output CUlTent equals the input voltage at C125 divided by the value of R158. Thus the voltage gain is dependent on the value of the load. In this way many such intercom stations can be connected in parallel without each successive station loading the line. A single load resistor is usually located in the power supply for the wired intercom. On versions 3 and later, U I07B is used to drive the lower end ofTIOl. This section is not a current source and was added to provide more headroom. To this end, U107 is operated from the higher voltage ahead of the regulator. S 104 is a 9 section DIP switch which is used to configure the base for compatability with a specific wired intercom. S103 functions as either an intercom onloff switch.(Telex, Clearcom standard) or as a channel AlB switch (RTS, Clem'com TW). In the case where the intercom interface is disconnected by S 103, R 186 functions as the load resistor. The full secondary ofTlOl is used for 300 ohm intercoms; the tap is used for 200 ohm systems. On version 2 and later, S 112 allows selection of either low output (100 mY) or high output (800 mY). 3-27 Intercom Input Since U 107A is a current source, signals arriving from an external intercom appear unloaded at pin 1 and are coupled via C126 and R154 to U106. To prevent intercom output signals from appearing at the output of U106, these signals are nulled by the branch containing C124, VRlOl and R152. U 106A and U 109 form a peak limiting am plifier similiar to that described for the microphone amplifier above, except that CA10l is used instead of a JFET to control the gain. The reason for this is that the higher level signals being handled by U 106A would cause high distortion if a JFET were used. CA10l is merely an LDR (light dependent resistor) together with an LED in the same package. More current through the LED reduces the value of resistance. Headset and Speaker Amplifiers U 111 and Ul19B (U107B in versions 1 and 2) drive the headset while U108 drives the external speaker jack. On versions 1 and 2 this signal was derived by mixing the microphone signal with the intercom output, via R175 and R177. On later versions the intercom output alone is used, being first amplified by U119A. S112B maintains the headset/speaker level constant when switching intercom output levels. Auxiliary Output UllOA mixes together intercom input, microphone, and receive board signals. U11 OB inverts the resultant to provide a balanced output. Remote Transmit Circuit When the transmit switch on the rear panel is in the remote position, the transmitter will only operate when at least one receive squelch is open. On versions 1 through 4 this is done with Ul15 which turns on Q109. Versions 3 and 4 have a circuit board error, however, which prevents this option from working. To correct this move the inputs of Ul15 to the left side (on the schematic) of R195, R198, R20l, and R204. The version 3 and 4 schematics show these inputs as they are unmodified, that is, connected to the right side of the resistors. On versions 5 and above, U 115 is replaced with Ql12, Ql13, Ql14 and Ql15 and no modifications are necessary. Power Supply Q 108 and U114 form a 10 volt regulated power supply. On versions 1 and 2, ZD101 is used as the 5 volt reference while on later versions this comes from U 117. U 112 and U 113 are also supplied by U1l7. Transmit Mixer and Filter U 106B mixes the intercom input, auxiliary input, microphone and receive board signals together to modulate the transmitter. VR102 is used to set the level going into the transmit compressor for proper tracking. On versions 3 and later, U118 acts as a four pole Chebyshev low pass filter with a cutoff frequency of 5 KHz. This is to prevent transmission of the 20 KHz tone which Telex intercoms use as the call signal. 3-28 8. Connect the signal generator to the Receive Antenna jack. Set the deviation to ± 3 KHz at 1 KHz. Set the output to 1 mV. Set the frequency to the channel 1 frequency listed in the chart of the receive board alignment.
