Anleitung Zusammenfassung
A fast time constant causes the receiver gain and the S-meter to react quickly to changes in the input signal. A fast AGC setting is particularly useful in the following situations: • Tuning rapidly • Receiving weak signals • Receiving high-speed CW Unlike other transceivers, the TS-2000’s digital AGC circuit allows you to adjust the time constant from slow to fast in 20 steps, where 1 is the slowest and 20 is the fastest. Furthermore, you can switch the AGC OFF if you desire. For your convenience, the following default AGC time constant has already been programmed. SSB: Level 7 CW: Level 12 FSK: Level 14 AM: Level 5 To change the default time constant: 1 Press [8/ AGC/OFF]. • The AGC time constant scale appears on the sub dot-matrix display. 2 To select a slower time constant, turn the MULTI/ CH control counterclockwise. The bar indicator moves from F(ast) to S(low). To select a faster time constant, turn the MULTI/ CH control clockwise. The bar indicator moves from S(low) to F(ast). 3 If you want to turn the AGC OFF, press [FUNC], [8/ AGC/OFF]. Note: You cannot adjust the AGC time constant on the sub-receiver. 2 If required, press [CLEAR] to reset the RIT offset to 0. 9 COMMUNICATING AIDS TRANSMITTING n Delay Time VOX (VOICE-OPERATED TRANSMIT) VOX eliminates the necessity of manually switching to the transmit mode each time you want to transmit. The transceiver automatically switches to transmit mode when the VOX circuitry senses that you have begun speaking into the microphone. When using VOX, develop the habit of pausing between thoughts to allow the transceiver to drop back to receive mode briefly. You will then hear if anybody wants to interrupt, plus you will have a short period to gather your thoughts before speaking again. Your listeners will appreciate your consideration as well as respect your more articulate conversation. VOX can be switched ON and OFF independently for CW and the other modes, excluding FSK. Press [VOX/ LEVEL] to toggle between VOX ON and OFF. • The VOX LED lights. ¦ Microphone Input Level To enjoy the VOX function, take the time to properly adjust the gain of the VOX circuit. This level controls the capability of the VOX circuit to detect the presence or absence of your voice. In CW mode, this level cannot be adjusted. 1 Select USB, LSB, FM, or AM mode. 2 Press [VOX/ LEVEL] to switch the VOX function ON. • The VOX LED lights. 3 Press [FUNC], [VOX/ LEVEL]. • The current VOX gain appears on the sub dot-matrix display. 4 While speaking into the microphone using your normal tone of voice, adjust the setting (default is 4) using the MULTI/ CH control until the transceiver reliably switches to transmit mode each time you speak. • The selectable gain range is from 0 to 9. • The setting should not allow background noise to switch the transceiver to transmit mode. Note: The VOX gain level can be adjusted even if VOX is switched OFF or while you are transmitting. If the transceiver returns to receive mode too quickly after you stop speaking, your final word may not be transmitted. To avoid this, select an appropriate delay time that allows all of your words to be transmitted without an overly long delay after you stop speaking. 1 Select USB, LSB, FM, or AM mode. 2 Press [VOX/ LEVEL] to switch the VOX function ON. 3 Press [FUNC], [KEY/ DELAY]. • The current setting appears on the sub dot- matrix display. The default is 50. 4 While speaking into the microphone using your normal tone of voice, adjust the MULTI/ CH control such that the transceiver switches to receive mode after you have stopped talking. • The selectable range is from 5 to 100 (150 ms to 3000 ms) in steps of 5, or OFF. 5 Press [FUNC], [KEY/ DELAY] to set the VOX delay. 9 9 S SPEECH PROCESSOR The Speech Processor levels out large fluctuations in your voice while you speak. When using SSB, FM, or AM mode, this leveling action effectively raises the average transmit output power, resulting in a more understandable signal. The amount of voice compression is fully adjustable. You will notice that using the Speech Processor makes it easier to be heard by distant stations. Transmit power Speech Processor Transmit power Time OFF Speech Processor Time ON 1 Select USB, LSB, FM, or AM mode. 2 Press [PROC/ LEVEL] to switch the Speech Processor ON. • The PROC LED lights. 3 Press [FUNC], [PROC/ LEVEL] to enter the Speech Processor input level adjustment mode. 4 As you speak into the microphone, turn the MULTI/ CH control so that the compression meter indicates that the compression level is around 10 dB while you speak. • Using higher compression will not improve your signal clarity or apparent signal strength. Excessively compressed signals are more difficult to understand due to distortion and are less pleasant to hear than signals with less compression. 5 Press [FUNC], [PROC/ LEVEL] to exit the Speech Processor input level adjustment. 6 Press [MIC/ CAR] to enter the Speech processor output level Adjustment. • As you speak into the micro...
