|Kenwood TS-700 Transceptor|
|Descripción:||2m All Mode Transceiver|
1. A fully solid-state, all-mode amateur transceiver, the Model TS-700 provides high-quality communications on SSB, FM, AM and CW in the 144-MHz band. 2. It operates with dual power supply, AC and DC, and is designed for two duties—STATIONARY and MOBILE—with emphasis on stationary duty. 3. The TS-700 is a highly sophisticated amateur radio transceiver with the frequency coverage in two bands, 144 to 145 MHz, and 145 to 146 MHz, respectively. Also included in the equipment are a built-in VFO circuit and an additional provision for RPT operation with the frequency coverage from 145 to 146 MHz for reception, and 144.4 to 145.4 MHz for transmission. 4. A newly developed two-speed dial mechanism facilitates tuning: MAIN TUNING knob (inner) for closer tuning covers a change of 25 kHz by one complete rotation; QUICK (COARSE) TUNING knob (outer) covers a change of 100 kHz similarly. You can tune in quickly with pin-point accuracy—the feature which will prove very useful in receiving single-sideband (SSB) signals. 5. MAIN DIAL is graduated to provide readings accurate to 1 kHz, presenting a circular (360 degrees) scale from zero to 100 kHz. SUB-DIAL is a similar scale graduated in intervals of 50 kHz to cover a total range of 1 MHz for a complete rotation. 6. A total of 11 fixed oscillator circuits (to be loaded with optional crystals) are provided: these selective circuits are good for each of the two selective bands, 144 MHz and 145 MHz, so that you virtually have a total of 22 fixed channels, each for making available a certain operating frequency and closely select the operating frequency within the assigned band. Moreover, a channel-in-use indicating device is included to tell you visually which of the crystal-loaded channels is in service. 7. A noise blanker (NB) circuit of the type adopted in many other HF products of our make and widely acknowledge for excellent noise eliminating performance is included. Such pulse signals as those coming from automotive ignition systems are beautifully excluded from audio output. 8. For improve FM-mode operation, a squelch circuit of noise filter type is added to the FM unit. 9. A tuner which uses a voltage variable capacitor is built in the receiver RF stage to minimize cross-talk and spurious interferences, and a high "Q" tuning circuit in the antenna input stage for excellent selectivity. 10. A balanced-type mixer circuit based on the use of field-effect transistors (FET) has been adopted for the pre-mixer and heterodyne mixer. These mixers assure improved rejection of spurious signals during transmission. 11. The IF stage (SSB, AM, CW) is provided with a 6-element crystal filter. The use of wide-band and narrow-band ceramic filters assures outstanding selectivity during FM reception. 12. The built-in RF gain control is of threshold type and, as such, ensures an optimized S/N ratio at all times in receiving SSB signals. 13. Speaker output is free from distortion: this owes to the amplifier-type AGC circuit. Signals transmitted are accompanied by little or no splutter and free from distortion: this owes to the advanced ALC circuit. The AGC circuit comprises such time-constant elements that this constant is "slow” in SSB mode but "fast" in FM, AM or CW mode. 14. A marker signal circuit, operating with a high-precision crystal oscillator which runs at 1 MHz, is included to enable you to calibrate the tuning dial extremely accurately at the edge of a frequency band. 15. The "S" meter is of our proprietary type. Its indication does not go beyond and "over the scale" even when an unusually intense signal comes in, as in FM-mode operation. This property of the meter enables you to verify the FM center frequency at the face of this meter.
