9 SPECIALIZED COMMUNICATIONS SLOW SCAN TV/ FACSIMILE Slow-scan Television (SSTV) is a popular application for transmitting still images over the air, from one station to another. Instead of trying to describe your station, simply showing it is much faster. Transmitting images over the air requires a scan converter, besides a transceiver. A scan converter transforms images taken with a video camera into audio signals that can be fed into your transceiver.
REJECTING INTERFERENCE IF FILTER The IF filters are designed for selecting the exact range of intermediate frequencies that are sent to the next stage in the receive circuit. Interference adjacent to the desired signal can be reduced by selecting a narrow bandwidth filter and/ or shifting the center frequency of the filter. To more effectively remove interference, combine the IF filtering and the DSP filtering (AF) described on pages 46 and 47.
10 REJECTING INTERFERENCE DSP FILTERS Adjust KENWOOD digital signal processing (DSP) technology is adapted to this transceiver. Using DSP filtering (AF), you can control the bandwidth, cancel the multiple jamming beat, and reduce the noise level using DSP filtering technology. HI ■ SSB/ FM/ AM 1 Press [MODE] to select SSB, FM, or AM mode. 2 Press [FIL/ NAR].
10 REJECTING INTERFERENCE BEAT CANCEL (SSB/ FM/ AM) NOISE BLANKER Two types of Beat Cancel DSP filters are available. Beat Cancel 1 (BC1) is effective for removing a weak beat or continuous beat signals. Beat Cancel 2 (BC2) is effective for removing intermittient beat signals, such as CW signals. Noise Blanker was designed to reduce pulse noise such as that generated by automobile ignitions. Noise Blanker does not function in FM mode.
10 REJECTING INTERFERENCE DSP RX MONITOR DSP FILTER FOR DATA COMMUNICATION (SSB/ FM) The DSP filter for Data Communication is designed to improve the reception tone readability, especially for PSK31 and other new digital modes. The DSP RX Monitor function temporarily cancels IF filter selection and DSP filter settings so that you can confirm the conditions of current reception frequency nearby. To use the DSP RX Monitor function, first assign the PF key on the panel (or Mic PF keys) {page 64}.
10 REJECTING INTERFERENCE PRE-AMPLIFIER Switching the Pre-amplifier OFF may help reduce interference from adjacent frequencies. Press [ATT/PRE/ ANT 1/2] to cycle through “ATT” / “PRE” / “ ” (OFF) then return to “ATT”. Select “PRE” to turn the pre-amplifier ON. When it is ON, the signal is amplified approximately 12 dB. • “PRE” appears when the function is ON. The ON/ OFF setting will be automatically stored in the current band.
MEMORY FEATURES MEMORY CHANNELS STORING DATA IN MEMORY The transceiver provides you with 100 memory channels, numbered 00 to 99, for storing operating frequency data, modes and other information. Memory channels 00 to 89 are called Conventional Memory Channels. Memory channels 90 to 99 are designed for programming VFO tuning ranges and scan ranges. The data you can store is listed below.
11 MEMORY FEATURES ■ Split-Frequency Channels MEMORY RECALL AND SCROLL 1 Press [A/B / M/V] to select VFO A or VFO B. • “tA” or “tB” appears to show which VFO is selected. There are 2 modes which allow you to retrieve frequencies and associated data that you stored in a memory channel: Memory Recall and Memory Scroll. 2 Select the frequency, mode, etc. to be stored. • This frequency and mode will be used for transmitting.
11 MEMORY FEATURES ■ Memory Scroll 1 Press [QMI/ M.IN] (1 s) to enter Memory Scroll mode. • The memory channel that was last selected appears. MEMORY TRANSFER ■ Memory \ VFO Transfer After retrieving frequencies and associated data from Memory Recall mode, you can copy the data to the VFO. This function is useful, for example, when the frequency you want to monitor is near the frequency stored in a memory channel. 1 Recall the desired memory channel {page 51}.

MEMORY FEATURES ■ Programmable VFO Using the start and end frequencies that you stored in channels 90 to 99, Programmable VFO restricts the frequency range that you can tune with the Tuning control. One application of this function is to help you operate within the authorized frequency limits of your license. 1 Press [A/B / M/V] (1 s) to enter Memory Recall mode. 2 Turn the MULTI control, or press Mic [UP]/ [DWN] to select a memory channel from 90 to 99.
11 MEMORY FEATURES 1 Select the frequency, mode, etc. on the transceiver VFO. QUICK MEMORY Quick memory is designed to quickly and temporarily save data without specifying a particular memory channel. Use Quick memory to store data you will not use in future operating sessions. For example, as you tune across the band looking for DX, it is convenient to store stations that you want to contact. You can quickly jump between several different memory channels as you monitor them. 2 Press [QMI/ M.IN].
SCAN Scan is a useful function for hands-off monitoring of your favorite frequencies. By becoming comfortable with all types of Scan, you will increase your operating efficiency. 1 Press [SCAN/ SG.SEL] (1 s) in VFO mode. • “VGROUP -- n” (where n represents a VGROUP number from 0 to 9) appears on the sub-display. This transceiver provides the following types of scans. 2 Turn the MULTI control to select the Program Scan memory (VGROUP–0 to VGROUP–9).
12 SCAN VGROUP–9). As you select the Memory Channel, “on” or “oFF” appears on the main frequency display. “on” signifies that the memory channel is active for the program scan and “oFF” signifies that the memory channel group is inactive for the program scan. 4 To activate the Program scan frequency range, select the desired VGROUP number by turning the MULTI control. Then, press [ ] to select “on” for the VGROUP (channel). When a channel is activated for the Program Scan, “on” appears on the display.
12 SCAN MEMORY SCAN ALL-CHANNELSCAN Memory Scan monitors all memory channels in which you have stored frequencies (All-channel Scan) or only a desired group of memory channels (Group Scan). Use the following procedure to scan all the memory channels that contain frequency data in sequence, ignoring the Memory Group number. Scan automatically stops at a channel where a signal is present, regardless of the operating mode.
12 SCAN GROUPSCAN ■ Performing Group Scan 100 memory channels are divided into 10 groups so that you can select one or more groups to be scanned, depending on the situation. Group Scan starts with the smallest group number and repeats the sequence. For example, if you selected “on” for MGROUP–3, MGROUP–5, and MGROUP–7, the transceiver scans the channels in MGROUP–3 / MGROUP–5 / MGROUP–7 / MGROUP–3 and so on.
OPERATOR CONVENIENCES ANTENNAS Two antenna connectors are available for the HF/ 50 MHz band on the TX/ RX unit rear panel {page 16}. Press [ATT/ PRE/ ANT1/2] (1 s) to select ANT 1 or ANT 2. • “1tANT” or “ANTs2” appears to indicate which antenna is selected. The ANT 1/ ANT 2 setting will automatically be stored in the antenna band memory. Next time you select the same band, the same antenna will be automatically selected. Antenna Selection Frequency Range (MHz) 0.03 ~ 2.5 2.5 ~ 4.1 4.1 ~ 6.9 6.9 ~ 7.
13 OPERATOR CONVENIENCES ■ Presetting After each successful tuning session, the AT Preset memory function stores the position of the tuning capacitor in the memory.
