User manual KENWOOD KCA-R10

[. . . ] This transceiver features a Digital Signal Processing (DSP) unit to process IF and AF signals. By taking maximum advantage of DSP technology, the KCA-R10 transceiver gives you enhanced interference reduction capabilities and improves the quality of audio. You will notice the differences when you fight QRM and QRN. As you learn how to use this transceiver, you will also find that Kenwood is pursuing "user friendliness". [. . . ] The larger the number, the faster the speed. 4 Press [KEY (DELAY)] again to complete the setting. Note: When using the semi-automatic "Bug" function, the selected speed applies only to the rate that dots are sent. Invalid Break-In Operation You can make break-in operation invalid while performing the keying speed adjustment. To switch this function ON, access Menu No. 43, and select "on" (default is "oFF"). · "VOX" blinks when break-in operation is enabled. 33 7 COMMUNICATING AIDS RISE TIME OF CW The rise time of a CW signal is the time for the RF output to rise to its maximum power after the key is closed. 1 Press [MENU], then press [Q-M. IN]/ [Q-MR] or turn the MULTI/CH control to select Menu No. 2 Press [M. IN]/ [SCAN (SG. SEL)] to select "1", "2", "4", or "6" (default). · The default setting of 6 ms is fine for slow or medium keying speeds and normal weighting (dot/ dash ratio). 1, 2, or 4 ms are good for faster keying speeds. 3 Press [MENU] to exit Menu mode. CW MESSAGE MEMORY This transceiver has 4 memory channels for storing CW messages. Each memory channel can store approximately 50 characters (equivalent of 250 dots). The default is ON. BUG KEY FUNCTION The built-in electronic keyer can also be used as a semi-automatic key. Semi-automatic keys are also known as "Bugs". When this function is ON, dots are generated in the normal manner by the electronic keyer. Dashes, however, are manually generated by the operator by holding the keyer paddle closed for the appropriate length of time. To switch this function ON, access Menu No. The default is OFF. Note: When the Bug Key function is ON, CW Message Memory (see below) cannot be used. 3 Begin sending using the keyer paddle. · The message you send is stored in memory. 4 To complete the message storage, press [CLR] or [CH1 (REC)]/ [CH2 (REC)]/ [CH3 (REC)]/ [RX/4 (REC)] to stop. · When the number reaches 100(%), the memory becomes full and recording automatically stops. Note: If you do not operate the keyer paddle after starting to record a message, a pause is stored in the channel. 34 7 COMMUNICATING AIDS Checking CW Messages without Transmitting 1 Press [CW/FSK (REV)] until you select CW mode. 2 If Break-in is ON, press [VOX (LEV)] to turn VOX OFF. 3 Press [CH1 (REC)], [CH2 (REC)], [CH3 (REC)], or [RX/4 (REC)] to select the channel to be played back. · To play back the messages stored in the other channels in sequence, press the corresponding channel keys during playback. [. . . ] 2 Press [A/B (A=B)] + [ ] to switch the transceiver ON. · A confirmation message appears on the display. 3 Turn the MULTI/CH control and select "VFO RESET". 78 15 TROUBLESHOOTING OPERATION NOTICES The transceiver has been designed and engineered to avoid possible hardware glitches. However, you may notice the following symptoms when you operate the transceiver. [. . . ]
