30BT Tuning Procedure 1) VCO adjustment a) Set a frequency at CH001. b) Connect DC volt-meter to TP1. c) Adjust VC101 until DC volt-meter shows at 0.9V. d) Set a frequency at CH240 and then make sure a DC volt-meter shows at less than 2.1V. 2) RF Output power adjustment a) Set a frequency at CH121. Disconnect an antenna. Set SW2 at CN5. b) Connect a spectrum analyzer and a power meter to CN5. c) Adjust VC2 to minimize a spurious with maintaining carrier. d) Make sure the spurious should be less than 40dB less than carrier. e) Adjust VC3 until power shows at 15mW. 3) TX Frequency adjustment a) Set a frequency at CH 121. b) Connect a frequency counter to CN5. c) Adjust VC1 until frequency counter shows at 800.000MHz + 2kHz. 4) AF Deviation adjustment a) Connect an oscillator output to mic terminal. (Should use 10μF/16V capacitor between them and + side should be connected to mic terminal.) b) Set the output of oscillator at -60dBm at 1kHz. c) Adjust VR1 until level of TP4 become at -33dBm. d) Adjust VR2 until deviation become at 5.0kHz + 0.5kHz. e) Adjust VR5 until one AF level meter (5pcs small square) is shown. 5) Tone modulation adjustment a) Turn off the Audio. b) Connect terminal TP6 to ground. c) Adjust VR4 until the deviation become 3.0kHz + 0.2kHz. d) After adjustment should to set SW2 at antenna.

From 100 to 250% of the authorize3d band- width they are attenuated by at least 35dB and beyond 250% 43 log(Po) dB. The plot shows the transmitter modulated with 15000 Hz(the highest modulation frequen- cy), adjusted for 50% modulation plus 16 dB. The spectrum analyzer was set with the un-modulated carrier at the top of the screen. The test procedure diagram and occupied bandwidth plot follow.
