1、DVS.2 DigitalRecorder YAESU IiIUSEI CO., LTD. C.P.0. Box 1500 TOKYO, JAPAII voice Oaeruiew The DVS-2 is a digital voice recorder designed especially for SSB, AM and FM operation with new model Yaesu transceivers such as the FT-1000 having a special jack for connection of the DVS-2 on the rear panel.

2、 It offers two independent functions: recording received signals for playback later in the loudspeaker/headphone, and recording signals by the microphone for playback later over the air (during transmission). Each mode uses its own memory, so both modes can be used to retain data at the same time. I

3、nstallation Connect the DVS-2 cable to the DVS-2 jack on the rear of the transceiver. You must also have a microphone connected to the MIC jack on the front panel of the transceiver to record your voice for transmissions. DVS-T Controls (Refer to the descriptions on the facing page) page 1 YAESTI ME

4、SSAGE MODE r | E 384 (1) PLAY, REC & TX LEDs These three indicators light or flash to indicate the status of the DVS-2. The PLAY LED glows green when playing back stored data, the REC LED glows yellow when recording, and the TX LED glows red when the DV$ 2 is keying the transmitter to play back over

5、 the air. Also, the pLAy and REC LEDs flash when waiting for you to make a memory selection (with a numbered button). (2) MESSAGE MODE Slide Switch This selects the mode for recording messages to be played back over the air: for either two 8-second messages, or four 4-second messages. chang- ing you

6、r selection does not erase previously stored messages, so you can use this switch to combine two pairs of 4-second messages. (3) MESSAGE NR Selection Buttons & LEDs (1 through a) These buttons select which message to record via the microphone or pray back over the air. The LED above each button glow

7、s red when a message has been stored in that slot. The 3 and 4 keys (and LEDs) are only func- tional when the MESSAGE MODE switch is set to the 4 x 4 sEc position. (4) MON!Button After recording a message via the microphone, press this button (fol- lowed by a message number button) to play back that

8、 message in the loudspeaker (instead of over the air). (5) MEMO Button Press this button (followed by a message number button) to record a mes- sage via the microphone. (6) PLAY Button After recording received signals, press this button to play them back in the transceivers loudspeaker. (7) REC Butt

9、on Press this button to start the receiver recorder. The recorder will run con- tinuously (recording an 16-second loop) until you press the srop button. (8) STOP Button Press this button to stop any recording or playback operation. page 2 Receizter Recording when used in this mode, the DVS-2 maintai

10、ns a continuous recording of the last (approximately) 16 seconds of audio from the main receiver. This can be particularly helpful in picking out callsigns during a pileup, as you can replay the same recording as often as you like (until you record over it). The record/playback process in this mode

11、is analogous to an 16-second endless tape - that is, you can turn the recorder on and off to record up to a total of 16 seconds of small segments of audio, or you can leave the recorder running to get one 16-second segment. In any case, the recorder overwrites data more than 16 (recording) seconds o

12、ld. J ro start the receiver recorder just press the REC button. The yellow REC LED will light (and stay lit). J when you hear something you want to play back, press the srop button (the neO LED will turn off), and then press the pLAy button. Now the green PLAY LED will light as recorded audio is pla

13、yed back through the main receiver audio channel. Note that if you record for less than 16 seconds, playback will start at the point you first started recording (no rewind, necessary). Howeve4 if you record for more than 16 seconds, playback will begin at the point 16 seconds before you stopped reco

14、rding. In either case, playback will repeat any re- corded audio every L6 seconds. You can stop the playback at any time by pressing srop. If you then press PLAY again, playback will continue from the point you stopped it. Receiaer Recording with the FT-7000 As the DVS-2 uses only the main receiver

15、audio channel of the FT:1000, you can play back recordings without missing real-time action by using the A B button on the FT-1000 to set the two VFOs to the same frequency. with stereo headphones, this allows you to continuaily monitor signals on the sub vfo audio channel while playing back recordi

16、ng on the main channel. page 3 Recording B Transmitting Messages This mode allows the DVS-2 to record either two g-second messages or four 4-second messages of audio from the microphone, such as contest exchanges or station IDs. Each can then be playedback, either in monitor mode (without transmissi

17、on),or directly over the air. Note that the digital memory used in this mode is independent from that used for recelver recording (so you can store both types of memory without interfering with one another). The 8- and 4-second messages share the same memory, so two 4-second message segments (1 and

18、2 or 3 and 4) can be combined into one g_second message for transmission, as indicated in the table below. Memory Segments & Message Numbers Button Pressed Segment(s) Used in Record/plavback 2 x 8-second Message Mode 4 x 4-second Message Mode 1Segments 1 & 2Segment 1 2Segments 3 & 4Segment 2 3no fun

19、ction Segment 3 4 no function Segment 4 Message Recording Before you record for transmission, check that the MESSAGE MoDE switch is set for the size message you want to record, either 4-second or 8-second (see the table above and the Example in the next section for help with this decision). You do n

20、ot need to press ih. prr switch while recording a message/ although you can, in which case your audio will be transmitted and recorded simultaneously. J Get your microphone readl,and then press the MEMO button (the vellow REc LED will blink). J Now press the numbered key for the segment (or segment

21、pair) to record (only 1 or 2 for the &second mode), and start talking (d,o not press the PTT switch unless you want to transmit at the same time vou are recording). The REC LED will stop blinking and stay on for the recording period (4 or 8 seconds), and then turn off. Arso, the red LED above the pa

22、ge 4 numbered key you pressed will come on (if this segment was previously empty) and stay on, indicating this segment is now storing data. To stop recording at any point before the selected segmenfs time limitis up, simply press STOP. This is the preferred method, since it eliminates any dead time

23、remaining from your last-recorded word and end of the time segment(which would keep your transmitter unnecessarily keyed for a short period). In any case, your message can not exceed the 4 or 8- second limit. Dont worry if you didnt have enough time to finish your phrase/ you can repeat the above st

24、eps to rerecord the same message - the previous message will be overwritten. (Note that there is no rewind step required.) Checking Your Recording Without Transmitting You can check the contents of a memory segment or pair without playing it back over the air, just by pressing ll|oNl followed by the

25、 appropriate numbered key. The green REC LED blinks until you press the numbered key, and then stays on during the playback period. We recommend always using this to check the results immediately after making a recording and before playing it back over the air. If you have recorded several 4-second

26、segments that you intend to combine during playback, move the MESSAGE MODE switch to the 2 x 8 SEG position to hear how the segments sound when played back together. Note from the table on the preceeding page that, in the 8-second mode, the 1 button plays back segments 1 and 2, while the 2 button pl

27、ays back segments 3 and 4. Clearing All Memory Although it should not normally be necessary,you can clear the contents of all memory (both that usedfor receive and transmit recording). J Using a sharp object, press the switch inside the hole on the leftside of the DV$2 momentarily. D Wait at least f

28、ive seconds, then press the PLAY button. The green PLAY LED should light. O Press the STOP button. page 5 On The Air Playback After recording a memory segment, you can play it back over the air by pressing the appropriate numbered button. The green pLAy and red TX LEDs will both light for a maximum

29、of either four or eight seconds, accord- ing to the setting of the MESSAGE MODE switch. Example of Combining Messages for Transmission since you will probably want to take advantage of combining messages for playback, you may want to take a few minutes to plan out your segment recording strategy. Co

30、nsider the following example: using the 4 segment-by-4-second mode, if you stored the segments like this: Segment 1: CQ Contest CQ Contest CQ Contest from, Segment 2: lyour callsign Segment 3: QSL, youre 5-9,200 (or whatever contest exchange is appropriate) Segment-4: QRzContestfromlyourcallsign, In

31、 the contest, you would then, J switch to the 2-segment-by-8-second mode to combine the segment pairs, J Press button 1 to send segments 1 & 2 (Ce Contest Ce Contest Ce Contest from your callsign) until you got a response, J Send the other stations callsign, J Press button 2, to send segments 3 & 4

32、(.eSLr 1lour S-g, ZO.IiZ Contest from your callsign). Notice in this example, you can operate the entire contest while only having to send the other stations callsign by voice - all repetitive informa- tion is handled by the DVS-2 (of course, in contests where you need to include a QSo count, you wo

33、uld want to arrange the segments a little differently, perhaps using the Lby-4-second mode for transmissions). page 6 YAE!SfT Pedormance wit hout compromis e.sM Copyright 1993 Yaesu Musen Co., Ltd.
