VHF Band Information: Theory of Operation 7.3 Theory of Operation 7.3.1 General Information 7-3 Your radio has two printed circuit boards: the Controller board, and the Radio Frequency (RF) board. The Controller board contains the CPU/Control section. The RF board contains the VCO/Synthesizer section, Transmitter section, Receiver section, Transmitter Audio circuitry, Receiver Audio circuitry, and Battery section. 7.3.
PAGE 50
7-4 VHF Band Information: Theory of Operation 7. The radio restores last power up state (i.e. state before the radio was turned-off). 8. Power is supplied to PLL circuitry. 9. Power is supplied to Rx and Rx VCO circuitry. 10. CPU sends data to PLL circuitry. If LOCK status is confirmed, radio continues the power-up sequence. Otherwise, PLL ERR is displayed. 11. If the Rx audio level is less than the pre-programmed squelch level, and other unmuting conditions are met, the radio will open squelch. 7.3.
PAGE 51
VHF Band Information: Theory of Operation 7-5 RF output from the active VCO is AC coupled to the synthesizer Q323 prescaler input at Pin 8. The divide counter chain in Q323, consisting of the dual-modulus prescaler, swallow counter and programmable counter, divides the VCO signal down to a frequency very close to 5.00kHz or 6.25kHz which is applied to the phase detector. The phase comparator compares the phase with the 5.00kHz or 6.
PAGE 52
7-6 7.3.6.3 VHF Band Information: Theory of Operation Power Control Output power is controlled by the CPU (Q101), the D/A converter (Q121), the dual Op-Amp (Q419), which is used as a differential amplifier and comparator. Current is sensed by the voltage drop across R445. When the radio is in high power mode, this voltage is compared to the D/A converter voltage at 5-watt. When the radio is in low power mode, this voltage is compared to the D/A converter voltage at 1-watt.
PAGE 53
VHF Band Information: Theory of Operation 7.3.7.3 7-7 Mixer The mixer is a DBM type (L407, Q407, L408). The mixer LO frequency is 45.1 MHz above the desired receiver frequency. When the receiver frequency is present, the mixer output will be a 45.1MHz signal. The mixer output is peaked for 45.1MHz at L410, C432 and R413, and the signal is filtered by crystal filter F402 and amplified by Q408 before being sent to IF IC Q506. The 45.1MHz IF signal and LO frequency of 44.645 MHz (X501) are mixed in Q506.

8-4 UHF Band Information: Theory of Operation 8.3 Theory of Operation 8.3.1 General Information Your radio has two printed circuit boards: the Controller board, and the Radio Frequency (RF) board. The Controller board contains the CPU/Control section. The RF board contains the VCO/Synthesizer section, Transmitter section, Receiver section, Transmitter Audio circuitry, Receiver Audio circuitry, and Battery section. 8.3.

UHF Band Information: Theory of Operation 8-5 6. This personality data is used to initialize the radio. 7. The radio restores last power up state (i.e. state before the radio was turned-off). 8. Power is supplied to PLL circuitry. 9. Power is supplied to Rx and Rx VCO circuitry. 10. CPU sends data to PLL circuitry. If LOCK status is confirmed, radio continues the power-up sequence. Otherwise, PLL ERR is displayed. 11.

8-6 8.3.5.3 UHF Band Information: Theory of Operation Synthesizer The frequency synthesizer is a large-scale monolithic synthesizer integrated circuit Q323. The synthesizer IC contains a dual modulus prescaler, programmable divide-by-N counter, prescale control (swallow) counter, reference oscillator, reference divider, phase detector, charge pump and lock detector. Also, included in Q323 are shift registers and control circuits for frequency controls and general device control.

UHF Band Information: Theory of Operation 8.3.6.3 8-7 Power Control Output power is controlled by the CPU (Q101), the D/A converter (Q121), the dual Op-Amp (Q419), which is used as a differential amplifier and comparator. Current is sensed by the voltage drop across R442. When the radio is in high power mode, this voltage is compared to the D/A converter voltage at 5-watt. When the radio is in low power mode, this voltage is compared to the D/A converter voltage at 1-watt.

8-8 8.3.7.3 UHF Band Information: Theory of Operation Mixer The mixer is a DBM type (L408, L409, Q407). The mixer LO frequency is 45.1 MHz above the desired receiver frequency. When the receiver frequency is present, the mixer output will be a 45.1MHz signal. The mixer output is peaked for 45.1MHz at L412, C426 and R412, and the signal is filtered by crystal filter F402 and amplified by Q408 before being sent to IF IC Q506. The 45.1MHz IF signal and LO frequency of 44.645 MHz (X501) are mixed in Q506.

Glossary of Terms Glossary Term Definition Active Scan State The state when the radio is in Scan Mode, and when the radio is rapidly moving through the Scan List Member channels looking for eligible transmission activity. If BCL is activated, the radio will check for channel activity before transmitting. If activity is detected, transmission is prohibited. For carrier squelch mode, radio will not transmit, if it is receiving carrier.
PAGE 128
Glossary-2 Term Definition Digital Private Line (DPL) DPL is a digital format transmitted along with the carrier. DPL allows for more use and privacy on a frequency. DPL is transmitted at a sub-audible (not able to be heard) frequency. Digital Private-Line™ Dual-Tone Multi-frequency. A Signaling System protocol widely used in the telephone industry. Two tones are transmitted simultaneously at different amplitudes for each keypad key press. A sequential series of Dual Tones makes a data word.
PAGE 129
Glossary-3 Term Definition Minimum Frequency The lowest frequency setting at which the radio is allowed to operate. The radio’s frequency range is defined as being between, or equal to, the Minimum and Maximum frequencies. This information is stored in the radio’s codeplug. The model number identifies the type of radio. This information is stored in the radio’s codeplug. For Normal Scan, the radio assigns equal priority to all members in the Scan List selected for the current channel.
PAGE 130
Glossary-4 Term Definition Priority #1 Scan List Member The first member in the current Scan List. When the radio is scanning a Scan List (Active Scan), 50% of the scans are targeted at the Priority #1 Member channel. Example: If the Priority #1 Member is P1, and the non-priority Scan List Members are Nn, then the scanning sequence is: P1 N1, P1 N2, P1 N3, P1 N4, P1 N5, etc.

Glossary-5 Term Definition Reverse Burst / Turn Off Code Causes a Tone Private Line (TPL) or Digital Private Line (DPL) code to be transmitted at the end of a transmission - once PTT is released, and while operating on the current channel. This sub-audible tone causes the receiving radio to mute its speaker before loss of a carrier is detected. Muting the speaker eliminates unwanted noise (squelch tail) during loss of carrier detection. Read Only Memory.
PAGE 132
Glossary-6 Term Definition Squelch Level The amount of carrier energy required to unmute the radio’s speaker upon satisfying the selected Carrier Squelch threshold. Low level allows more transmissions with less clarity to unmute the radio’s speaker. High level increases the squelch threshold causing a stronger carrier signal to be required before the radio’s speaker will unmute. This helps to reduce unwanted noise.
PAGE 133
Glossary-7 Term Definition User Defined PL Frequency VCO You can customize up to three non standard PL frequencies to provide more choices for PL. Voltage-Controlled Oscillator: an oscillator whereby the frequency of oscillation can be varied by changing a control voltage. Variable Frequency Operation. The radio user chooses frequencies instead of preprogrammed channels to operate the radio.
