TECHNICAL DESCRIPTION PR4000 WX FCC ID: BBOPR4000WX Page 1 December 6, 2002 A). GENERAL DESCRIPTION The PR4000 WX radio is a self-contained transceiver unit intended for use as a general communication tool. The PR4000 WX model is a combination FRS/GMRS unit and has 22 channels of which channels 1-7 share the FRS channels 1-7. The PR4000 WX has the capability of switching transmit power .5W, 2W and 3W with FRS channels 8-14 limited to .5W only. Other features include a CTCSS system with 38 pre- defined, user selectable sub-audible tones for channel quieting. The useable range, while dependent upon terrain, power setting and other radio propagation principles, is typically seven miles based on the transmit power specified at 3 watts ERP and 2 miles based on the transmit power of 1/2 watt ERP. Product features are as follows: MODEL PR4000WX FEATURES Number of Channels 22 CTCSS SubCodes 38 Range (Low Power) 2 Miles Range (Medium Power) 5 Miles Range (High Power) 7 Miles Alkaline Battery Source 4 AA Weather Channels 10 Transmitter Output Power 0.5/2/3 W Channel Indicator LCD Backlit LCD Yes Detachable Antenna No Call/Ring Alert 10 Tones Auto Squelch Yes Internal VOX Yes Automatic Battery Save Yes Auto Channel/User State Saver Yes Channel Scan Function Yes Channel Monitor Yes Key Lock Yes Supports NiMH Battery Source Yes Low Battery Alert and/or Gauge Both Water Resistant Yes Headset Jack Yes On/Off/Volume Rotary Belt Clip Included Yes Chg Contacts on radio bottom Yes TECHNICAL DESCRIPTION PR4000 WX FCC ID: BBOPR4000WX Page 2 B). FREQUENCY DETERMINING CIRCUITS The fundamental frequency for both the transmitter and the receiver local oscillators are controlled by a phase lock loop (PLL) circuit U300 (Toshiba TB31202). The frequency of operation of the voltage controlled oscillator (VCO), composed of Q50 and Q51 operating in cascode, is phase locked to a voltage controlled crystal reference (VCXO) operating at 10.475 MHz (X300). Compensation for temperature variations on the crystal reference is accomplished using a thermister (TH300) to change the reactance of the reference crystal circuitry. Compensation for voltage variations on the crystal reference is accomplished through a supply voltage regulator The VCO is locked to the fundamental of the transmit signal in the transmit mode and is locked to the receive 1 st LO (Fundamental channel frequency minus 21.4 MHz) in the receive mode. The crystal reference frequency is fed through a doubler circuit to generate the 2 nd LO of 20.950 MHz. C). TRANSMITTER CIRCUITS The transmitter amplifies the 0 dBm signal from the VCO to approximately 34.8dBm that is fed to the antenna. The transmitter is a three stage amplifier composed of Q200, Q201 and Q202. The first stage is operated class A, and the driver and final is operated class AB. The fundamental transmit signal is fed through a low pass filter in order to suppress the harmonics to below –60 dBc. Transmit power level setting is controlled by the micro-controller (U400). When pin 88 of U400 is driven to a logic low level Q200 is biased for 0.5W-conducted and 2W-conducted operation. When pin 88 of U400 is not driven by U400 to a logic level low Q200 is biased for 3W-conducted output mode. When pin 88 of U400 is driven low for 0.5W-conducted or 2W-conducted operation pin 11 of U400 is driven to a logic level high to drive Q203 to turn on D201 to change the matching network load condition to cause the transmitter to output 0.5W- conducted power. The desired frequency modulation of the carrier is accomplished by modulating the current in the VCO directly with the microphone audio signal. The microphone audio is conditioned with a three-pole high pass filter at 300 Hz (U230-C), a hard clipper circuit (U230-B) to limit maximum deviation to +/-2.5 kHz and a three-pole low pass or splatter filter at 2.7 kHz (U230-A). The low pass filter insures that the occupied bandwidth of the FM modulated signal meets FCC requirements under all input conditions. D). RECEIVER CIRCUITS The received signal from the antenna is band limited to 600 Mhz by the transmitter harmonic filter. The desired signal is fed to a low noise amplifier (LNA – Q101) centered from 460 to 470 MHz that provides approximately 15 dB of gain. The output of the LNA is filtered with a SAW filter (SF100) with passband of 460 to 470 MHz and stopband attenuation of 50 dB. The filtered receive signal is one input to the 1 st mixer, the other mixer input (1 st LO) is the output of the VCO at the desired channel frequency minus 21.4 MHz. The output of the mixer is tuned to the 1 st IF of 21.4 MHz. The 1 st IF fed to a crystal filter centered at 21.4 MHz with a bandwidth of 15 kHz. The filtered 1 st IF is then amplified by Q103 and fed to the 2 nd mixer input of the multi-function receiver IC (U130). The 2 nd LO (20.95 MHz) is generated by the 10.475 MHz VCXO that is the reference frequency for the PLL. The 2 nd mixer output of 450 kHz is filtered through a 6 section ceramic filter that in combination with the 21.4 MHz crystal filter provides approximately 55 dB of adjacent channel attenuation. The 450 kHz 2 nd IF is then amplified, limited and fed to a quadrature detector for FM demodulation. The resulting audio output signal is bandpass filtered from 300 to 3 kHz (U150-A, U150-B) and amplified to provide 350 mW of audio power (U160), which differentially drives the 16 ohm speaker. A squelch circuit is provided (U130 pins 10 through 14) to mute TECHNICAL DESCRIPTION PR4000 WX FCC ID: BBOPR4000WX Page 3 the receiver noise under low signal conditions. The squelch circuit amplifies and detects noise in a narrow bandwidth at approximately 7 kHz. When the detected noise exceeds a threshold set to trigger at approximately 12 dB SINAD receive signal strength, the audio output is muted. E). WEATHER RADIO SECTION The weather radio mode is controlled by data sent to U300 from micro-controller (U400). When the weather radio mode is selected the micro-controller (U400) …
