In modes other than FM, the third IF is 24kHz, and the IF signal is converted by an A/D converter and input CIRCUIT DESCRIPTIONinto DSP. The FM mode is detected in the FM IC, and the audio signal is converted by an A/D converter and input into the DSP. Under the following conditions, the fi rst IF oper-ates its reception in 11.374MHz double conversion.1) Modes other than AM or FM2) Amateur band within the 1.8/3.5/7/14/21MHz bands3) DSP fi lters bandwidth is 2.7kHz or lowerFig. 1 Frequency confi gurationPLLAD4111DDSAD9951DDSAD983511.374MHz1st IF73.095MHz1st IFADCDACDACADCDSP10.695MHz2nd IF3rd IFIFAIFBVCOFM MODRX MIXRX MIXTX MIXx2exceptFMRX MIXTXMIX455kHzFM ICNJM2591FMTX/RXMIXx2x2X50215.6MHzAF24kHz24kHzAF OUTMIC INANTRX-2RX-1Reference Signal GeneratorThe reference frequency (fstd), which is used to control the individual LO frequencies, oscillates at 15.6MHz in a crystal oscillation circuit (X502, Q501). This 15.6MHz signal passes through a buffer (Q502) and is doubled in a multiplier (Q503) to generate a 31.2MHz signal. The 31.2MHz signal is used as a reference signal for LO3 (the third local oscillator) DDS (IC601). The 31.2MHz signal is doubled in multipliers (Q504, Q505) to generate a 62.4MHz signal. The 62.4MHz signal is used as a reference signal for LO1 (the fi rst local oscillator) PLL (IC801).The SO-3 (TCXO unit: 15.6MHz) is confi gured as an op-tion in this transceiver, so that you can replace the crystal oscillation circuit (X502, Q501) with the SO-3. When using the SO-3, remove the CN903 and CN904 short jumper wires in order to stop the operation of the crystal oscillation circuit (X502, Q501).LO1/ LO2/ LO3 LO1 (the fi rst local oscillator)The VCO (Q806) oscillates at 196.8MHz. Only the double frequency component, 393.6MHz, of this VCOs oscilla-tion output is extracted and input into PLL (IC801) pin 6. This input signal is divided into 1/N within the PLL. Also, the 62.4MHz signal (15.6MHz reference frequency x 4) is input into PLL pin 8 and divided into 1/R within the PLL. By a phase comparator in the PLL, the frequency divided into 1/N and the frequency divided into 1/R are compared, and then the frequency is locked. The comparison frequency (fø) at this time is 120kHz when transmitting FM, and 2.4MHz otherwise.393.6MHz signal locked by PLL (IC801) would be used as reference by DDS (IC803). The output signal from DDS (IC803) is 12.495MHz to 32.195MHz when RX-1 path is selected, amplified at the broad band amplifier (IC804), TS-590S6and then goes through BPF and is output as LO1. When RX-2 path is selected or when transmitting, 36.5625MHz to 66.5475MHz is output, amplifi ed by the broad band ampli-fi er (IC804), and then doubled in the multiplier (D652), goes through BPF, and is output as 73.120MHz to 133.095MHz LO1. LO2 (the second local oscillator)The reference oscillating circuits output signal 15.6MHz signal passes through a buffer (Q502) and is doubled in a multiplier (Q503) to generate a 31.2MHz signal. The 31.2MHz signal is also used as the DDS (IC601)s reference Fig. 2 Reference signal generator, LO1/ LO2/ LO3frequency, and therefore its resistance is divided. Then, the 31.2MHz signal is doubled in multipliers (Q504, Q505) to generate a 62.4MHz signal.The 62.4MHz signals high harmonic is cut in the BPF and the signal is amplifi ed in the amplifi er (Q506) to gener-ate LO2. If IFB is selected, the diode switch (D501) cuts the LO2 output. LO3 (the third local oscillator)The LO3 used in the modulator and the detector is gen-erated in the DDS (IC601). The DDS output signal passes through the buffer (Q602) and LPF to generate LO3.Q808Q663AMPBufferIC803DDSIC804AMPIC801PLLQ806VCODoublerIC601DDSLPFLPFLPFLPFLPFLPFLPFLPFD651D652L651BPFBPFHPFD659D670D671 D669D655 D660D654D663D661BPFBPFBPFD653D680 D681D667LO1LO2LO3D657D679D662D668X502,Q50115.6MHzOptionSO-3Q502BufferQ506BufferDoublerQ503DoublerQ504,Q505BufferQ601BufferQ602D501BufferQ801Q804FM MODBufferCIRCUIT DESCRIPTIONTS-590S7Table 1-1 LO1 frequency shift data IF=73MFrequency: 0.0360MHzHF TX/RXLO1DDS AD9951 (DEN1)USB LSB CW CW-R CWNRX TX RX TX RX TX RX TX RX TXFilter offset 1 +1.5k +1.5k 1.5k 1.5k 000000RIT ( RIT) - ( RIT) - ( RIT) - ( RIT) - ( RIT) -XIT - ( XIT) - ( XIT) - ( XIT) - ( XIT) - ( XIT)CAR correction IF10M_2.7k +(CAR1) +(CAR1) (CAR1) (CAR1) +(CAR1) +(CAR1) +(CAR1) +(CAR1) - -HF TX/RXLO1DDS AD9951 (DEN1)CWN-R FSK FSK-R AM FMRX TX RX TX RX TX RX TX RX TXFilter offset 1 0 0 (SHIFT/2) (SHIFT/2) (SHIFT/2) (SHIFT/2) 0000RIT ( RIT) - ( RIT) - ( RIT) - ( RIT) - ( RIT) -XIT - ( XIT) - ( XIT) - ( XIT) - ( XIT) - ( XIT)CAR correction IF10M_2.7k - IF=11MFrequency: 0.0321.5MHz (Amateur bands within 1.8/3.5/7/14/21MHz band only)HF TX/RXLO1DDS AD9951 (DEN1)USB LSB CW CW-R CWN CWN-R FSK FSK-RRX RX RX RX RX RX RX RXFilter offset 1 +1.5k 1.5k 0 0 0 0 (SHIFT/2) (SHIFT/2)RIT ( RIT) ( RIT) ( RIT) ( RIT) ( RIT) ( RIT) ( RIT) ( RIT)CARcorrectionIF11M_2.7k +(CAR2) (CAR2) +(CAR2) +(CAR2) - - - -IF11M_500 +(CAR3) (CAR3) +(CAR3) +(CAR3) - - - -( RIT): RIT frequency variable amount (9.99+9.99kHz)( XIT): XIT frequency variable amount (9.99+9.99kHz)(SHIFT): FSK shift width frequency (170Hz, 200Hz, 425Hz, 850Hz, Initial value:170Hz)CAR correction: SSB IF-Filter adjustment volume. 0 when using Narrow option fi lter.(CAR1): IF 10.695MHz, SSB Normal fi lter compensation value(CAR2): IF 11.374MHz, Normal fi lter compensation value(CAR3): IF 11.374MHz, Narrow fi lter compensation valueCIRCUIT DESCRIPTIONTS-590S8Receiver CircuitIn an amateur frequency band or mode that requires anti-proximate interference, the receive signal passes through the double conversion RX-1 path, and in other frequency bands and modes, it passes through the triple conversion RX-2 path.

This can be switched to approximately 20dB by removing the CN101 short jumper. Then, the signal passes th
