Tuning speed varies according to the controi rotation. However, this is not a scan function, therefore, tuning does not stop, even when detecting a signal. This control is convenient when you want to search both the main and sub bands. r—— FUNCTION The IF shift electronically changes the IF passband frequency to reject interference.

BASIC INSTALLATION 2 к Selecting a location Select a location for the transceiver that allows ade- quate air circulation, free from extreme heat, cold, or vibrations, and away from TV sets, TV antenna ele- ments, radios and other electro-magnetic sources. For a description and a diagram of accessory equip- ment included with the transceiver, see UNPACKING on the inside front page (p. i) of this manual. OPERATING ANGLE ADJUSTMENT 23 Antenna For radio communications, the antenna is of critical importance, along with output power and sensitivity. Select good antennas and mounting locations. The transceiver accepts a 50 @ antenna and less than 3:1 of Voltage Standing Wave Ratio (VSWR). The transceiver requires 2 antennas for 144 and 430 MHz operation. Of course, the transmission line should be a coaxial cable. The stand on the bottom of the transceiver provides two operating angles. mi Antenna connectors PL-259 CONNECTOR INSTALLATION (for 144 MHz antenna) (1) Coupling ring 30 mm 3) Solder Slide the coupling ring down, Strip the cable jacket and soft solder.

SS ea AFSK terminal unit connections The transceiver does not have an FSK mode for RTTY, AMTOR, PACKET, etc., however, you can operate these using AFSK in SSB or FM mode. The transceiver accepts data speed of up to 9600 bps. When using 9600 bps, set the internal switch to the “PACT” (packet) position. Refer to p. 48 for switch location. When operating AFSK, connect external equipment to the ACC(1) socket on the rear panel or to the microphone connector on the front panel as in the diagram below. When connected to the [MIC] connector, [MIC] and [AF] control adjustments are required. The [MIC] connector accepts up to 1200 bps.

The VFOs are called VFO A and VFO B. You can use a desired VFO to call up a frequency and operating mode for your operation. VFO is an abbreviation of Variable Frequency Oscil- lator, and traditionally refers to an oscillator. >—— CONVENIENT Use two VFOs as a quick memory When you find a new station but you wish to continue searching, the two VFO system can be used for quick memory storage.

The function shifts the receive frequency only up to +2.0 kHz in 20 Hz steps in SSB/CW mode (+ 10.0 kHz in 100 Hz steps in FM mode) without moving the transmit frequency. The shift frequency resolution can be selected for SSB/CW and FM modes separately using the L-set mode.

(pgs. 22, 42) ААА + IF shift function The IF shift function electronically changes the pass- band frequency of the IF (Intermediate frequency) and cuts out higher or lower frequency components of the IF to reject interference. The function shifts the IF frequency up to +1.2 kHz in 100 Hz steps in SSB/CW mode. The IF shift is especially effective in SSB operation and not available in FM mode. The IF shift function can be used for the main band only. (O Adjust the [SHIFT] contro! for a minimum inter- ference signal level. - The audio tone may be changed while the IF shift is in use.
