~ 3-7. SCAN 3-7-1. Memory scan Memory scan operates from memory channel 00 thru memory channel 99 at approximately 3-4 second in- tervals, or you may specify which memory groups you want to scan. Only these memory channels with data entered are scanned. 3-6-4. Entering/Transferring data in the split fre- quency channels Separate transmit and receiv[...]

Note: -~ ,'j The TS-440S microprocessor remembers the variou~ scan parameters that you have specified and will fol- low whatever you have entered the next time you press the SCAN key. In example 1 we want to scan only Group 2, so we would press the 2 key. In example 2 we want to scan Group 1 and Group 2, so we would press the 1 key and then th[...]

3-8. AFSK 3-8-1. Reception Note: An RTTY terminal is required to receive and dis- play/print the RTTY signal. 1. The AFSK mode utilizes the LSB carrier frequency, which conforms to international conventions. 2. When the optional YK-88C filter is installed, the nor- mal receiver bandwidth is 500 Hz when the SELEC- TIVITY switch is set to the AUTO po[...]

4. This 3rd IF frequency is either amplified and then demodulated by the FM detector IC, for FM operation, or applied to the 455kHz filter. After filtering the sig- nal is amplified and applied either to the SSB or AM detector circuits. 4-4.

4. Cut the lead of diode 065 located below the dip switch on the control unit. 5. Reverse steps 1.-3. to reassemble the radio. Notes: 1. When reassembling the radio make sure that you do not cut or pinch any wires between the chassis and front panel! 2. Do not alter the settings of the dip switch. They are factory adjusted, and damage or misoper- a[...]

10. REFERENCE 10-1-2. Mobile (1) Antenna Use a sturdy mount for the mobile antenna since HF antennas are larger (and have more wind load) and are heavier than VHF antennas. A bumper mount is recom- mended for general use. The ground side of the mount must be well grounded to the car body, since the body itself functions as the ground plane for the [...]

--J The antenna to be used should first be checked with a dip meter to insure that it is designed for your oper- ating band, then the impedance matching should be checked with an SWR meter. (Fig. 10-3) The VSWR should preferably be less than 1.5: 1 for stisfactory operation. For antenna adjustment refer to the antenna instruction manual. (4) Antenn[...]

10-2-2. Noise reduction In motor vehicles, noise is generated by the ignition system. Other sources of noise include the wiper and heater motors. Although the transceiver is equipped with a noise blanker to minimize ignition noise, it is imperative that some preventiye measures be taken to reduce the noise to the lowest possible level.
