Always use the EXIT key to return to the MAIN menu screen before disconnecting the radio. Improper exits from the SERVICE s c re e n s m a y l e a v e t h e r a d i o i n a n improperly configured state and result in seriously degraded radio or system performance. General An IBM PC (personal computer) and RSS (Radio Service Software) are required to align the radio. Refer to the applicable RSS Manual for installation and setup procedures for the software. To perform the alignment procedures, the radio must be connected to the PC, RIB (Radio Interface Box), and Test Set as shown inFigure 7-1. All SERVICE screens read and program the radio codeplug directly; you do NOT have to use the RSS GET/SAVE functions to program new tuning values. The SERVICE screens use the concept of the “Softpot”, an analog SOFTware controlled POTentiometer used for adjusting all transceiver alignment controls. Each SERVICE screen provides the capability to increase or decrease the ‘softpot’ value with the COMPUTER SYSTEM ANALYZER R2000 SERIES RF CABLE AUDIO OUT AUDIO IN TEST SET CABLE RKN4034 7.5 VDC POWER SUPPLY RTX4005B RADIO PORTABLE TEST SET RTX4005B PROGRAMMING CABLE/ BATTERY ELIMINATOR HKN9857 ANTENNA ADAPTER RIB RLN4008B 110 VAC Figure 7-1.

A graphical scale is displayed indicating the minimum, maximum, and proposed value of the softpot, as shown in Figure 3. oscillator should be checked every time the radio is serviced. The frequency counter used for this procedure must have a stability of 0.1 ppm (or better). 1. From the SERVICE menu, press F2 to select ALIGNMENT: TRANSMITTER & RECEIVER. 2. Press F5 to select OSCILLATOR softpot. 3. Press F6 to key the radio. The screen will indicate that the radio is transmitting. 4. Measure the transmit frequency on your frequency counter. 5. Use the UP/DOWN arrow keys to adjust the reference oscillator. Tuning Procedure NOTE Perform the following procedures in the sequence indicated. Reference Oscillator Alignment Adjustment of the reference oscillator is critical for proper radio operation. Improper adjustment will not only result in poor operation, but also a misaligned radio that will interfere with other users operating on adjacent channels.

Press F6 again to dekey the radio and then press F8 to program the softpot value. 1. From the SERVICE menu, press F2 to select ALIGNMENT: TRANSMITTER & RECEIVER. 7. Press F10, F10 to return to the SERVICE menu. 2. Press F3 to select the transmit deviation balance and deviation limit softpot. The screen will indicate the transmit test frequencies to be used. 3. Begin with the lowest test frequency shown on the screen. 4. Press F4 to select 60 Hz. 5. Press F6 to key the radio. Record this measurement. Squelch The squelch softpots set the signal to noise ratio at which the squelch opens. 1. From the SERVICE menu, press F2 to select ALIGNMENT: TRANSMITTER & RECEIVER. 2. Press F8 to select SQUELCH Adjustment. 3. Adjust the UP/DOWN arrow key to the minimum squelch value. 4. Set the RF test generator to the test frequency plus +500 Hz offset. 6. Press F6 again to dekey the radio, and press F4 to select 2.5 kHz. 5. Adjust the UP/DOWN arrow key until the squelch just closes. 7. 6. Monitor for squelch chatter; if chatter is present, continue to adjust the UP/DOWN arrow. Wait a few seconds and repeat step 7. Press F6 to key the radio, then use the UP/ DOWN arrow keys to adjust the deviation until the value in step 5 and the value in step 6 are equal. 8. 7. When no chatter is detected, press F8 to program this value. Press “ENTER” to select next softpot adjustment. Press F6 to dekey the radio. Press ENTER to move to next softpot value. 9. Press F8 to program the softpot value. 8. Press F10, F10 to return to the Service menu. Transmit Deviation Limit Transmitter Power 1. From the SERVICE menu, press F2 to select ALIGNMENT: TRANSMITTER & RECEIVER. 2. Press F7 to select the Tx POWER calibration softpot. The screen will indicate the transmit test frequencies to be used. 3. Press F6 to key the radio, and use the UP/ DOWN arrow keys to adjust the transmit power value. Press F6 to dekey the radio. Press ENTER to select next softpot frequency. 4. Press F8 to program the value. 5. Press F10, F10 to return to the SERVICE menu. The transmit deviation limit softpot sets the maximum deviation of the carrier. Tuning is performed for 25 kHz channel spacing. Transmit Deviation Balance (Compensation) & Deviation Limit Compensation alignment balances the modulation sensitivity of the VCO and reference modulation (synthesizer low frequency port) lines. Compensation algorithm is critical to the operation of signaling schemes that have very low frequency components (e.g. DPL) and could result in distorted waveforms if improperly adjusted. February 1997 68P02948C90-O 1. Press F10 to select the DEVIATION LIMIT ADJUSTMENT softpot. The screen will indicate the transmit test frequencies to be used. 2. Begin with the lowest test frequency shown on the screen. 3. With Test Box 4460A: inject a 1 kHz tone, 2000 mVrms. 4. Press F6 to key the radio, and use the UP/ DOWN arrow keys to adjust the deviation between 2.1 kHz and 2.4 kHz for 900 MHz. 5. Press F6 to dekey the radio. Press ENTER to move to the next softpot value. 6. Press F8 to program the softpot value. 7. Press F10, F10 to return to the SERVICE menu. 7-3 Radio Tuning Procedure GTX/GTX LTR/LTS 2000 Portable Radios Service Manua This page intentionally left blank 7-4 68P02948C90-O February 1997 SCHEMATIC DIAGRAMS, CIRCUIT BOARD DETAILS, & PARTS LISTS February 1997 68P02948C90-O 1 This document was created with FrameMaker 4.0.3 5V 5V SWB+ Q400 BCW68GLT1 3 TXB+ (SOURCE) 2 R419 10K PB401 MON 1 R400 680 3 SWB+ Q401 3904L 1 5R (SOURCE) 5V SWB+ 1 5V 5R 5R TXB+ 5V TXB+ 5V 5R 5R ANTENNA R416 2 SWB+ SWB+ SQ_ATT_IN R404 10K 43K GND 3 R424 200K C466 39PF 1 Q405 3906L R438 3.3K C401 2 39PF SQ_ATT_IN 7 TP402 1 TP402 ANTENNA_CONTACT 2 TRANSMITTER ANT_CONN DET_AUDIO RX_IN RX_IN DET_AUDIO (J200-4) C1 C0 C1 C0 DET_AUDIO RECEIVER PC3 PC2 PC1 PC0 C439 0.01UF TP401 1 TP401 GND 2 5V GND ADAPT PWR_REF ADAPT (J200-6) 5V (SOURCE) R408 20K 8 4 2 1 GND GND 6 5V_TAP 8 1 IN OUT 2 FDBK 7 SENSE 5 3 SHDN ERORR_ R411 43K J6 8 7 6 GND 4 R460 50.0K C419 18NF SCI_IN CR405 BYD17D 5 470 J200 1 CW 3 B+ R497 2 0.47UF 5V 1 SWB+ L460 2 150NH 3 SWB+ GND 2 20K C467 39PF 3 1 C421 R417 GND ADAPT RX_INJ TX_INJ 150NH R410 20K 2 1 SWB+(SOURCE) U420 LP_2951AC RSSI R401 120 L420 R409 43K R420 10K PB402 EMERG RSSI (J200-5) 2 R407 10K 9 NOT USED 5V ANTENNA_CONTACT R406 10K SW401 SW_FREQ_16POS CONNECTOR 3 R405 10K C475 39PF C473 39PF C479 39PF C457 39PF C477 39PF R414 470K C455 39PF R415 470K RX_IN 2 CCW 1 C418 10uF C460 39PF 4 VR460 1 MMBZ5235L DET_AUDIO 5 RSSI 1 VDD HC_CNTL CLK U400 DAC2 11 RESET DAC DAC1 9 3 EN BIAS_EN ANT_SEL 2 TEMP BATT 2_POLE_V 8 12 AUX FREQ_SW_DA R_T SCB1 17 DATA_IN SCB2 18 FREQ_SW0 19 SCB3 FREQ_SW1 FREQ_SW2 SCB4 20 5V C472 39PF C478 .01UF C456 .01UF C476 .01UF 6 C454 .01UF ADAPT MUTE 1 TX_INJ 5V SWB+ 5R FREQ_SW3 VSS 13 LOCK_DET WARP 1 LOCK_DET (J200-7) C445 .01UF C446 39PF C449 39PF EXP_AUDIO 2 SYNT_EN SYNT_EN (J200-8) SYNT_EN MOD_IN 3 MOD_IN(J200-9) R412 1.3K R422 1.3K TX_IN SPI_CLOCK (J200-24) 2.1MHZ TX_RX R489 2.7 R488 1K R490 2.7 HC_CNTL DET_AUDIO 2 SPI_DATA (J200-17) C438 4.7UF 1 Q412 HC_CNTL DISC RSSI 3906L EXP_AUDIO RX_IN TX_IN EXP_AUDIO RX_IN TX_IN IN HEAR CLEAR 5V 3 SWB+ R491 120K EDGE1 EDGE2 EDGE4 EDGE5 EDGE3 GND_EDGE_1 GND_EDGE_2 GND_EDGE_3 GND_EDGE_4 GND_EDGE_5 GND GND GND GND GND 1 1 1 1 1 EDGE6 GND_EDGE_6 GND 1 C465 0.1UF 2.5V C464 0.1UF 1 FROM U400-17 MUTE U405 LM2904DR 1 2 7 R496 330 5 U405 LM2904DR R467 10 R448 U409 CL1 CL2 CL3 CL4 CL5 CL6 C437 0.47UF R498 0 CL7 CL8 R499 0 C471 47PF R486 4.7K C429 4700PF C409 39PF C481 39PF C408 39PF C436 39PF 2 VR436 1 3 C470 470PF C469 47NF GND GND1 3 6 R450 C441 0.1UF 4 4.7UF R452 200K 10K 1 Q408 3906L C442 1000PF R451 C425 47NF R454 R447 5.6K R494 100K C453 2K C430 39PF INT_SPKR- J3 L405 150NH 39PF 5 5 4 4 6 6 L406 150NH 2.ALL RESISTORS MARKED "NO PART" ARE NOT ASSEMBLED.
