Kenwood FT-690S Specifications

The FT-690S is a radio transceiver made by Kenwood. You can power it by plugging it into an electrical outlet for stationary use, or by connecting it to a car's battery for mobile use. It picks up a variety of radio frequencies that you can scan for, monitor, and save in memory for future listening. After plugging the included microphone into the Kenwood FT-690S, you can transmit your voice or other audio over the radio.

Mode
- Radio modes of the Kenwood FT-690S are J3E (LSB and USB), A1A (CW), A3E (AM), F3E (FM) and F1A (FSK).
Operating Temperature
- The Kenwood FT-690S operates at temperatures ranging from 14 to 122 degree Fahrenheit.
Dimensions
- The Kenwood FT-690S measures 10 5/8 inches by 3 25/32 inches by 12 1/64 inches.
Weight
- The weight of the Kenwood FT-690S is 16.5 lb. with its antenna unit, and 13.9 pounds without the antenna unit.
Memory Channels
- The Kenwood FT-690S has 100 memory channels for storing frequencies, giving you the ability to retain many transmission wavelengths that interest you as you scan for them, and then quickly call them up again for future monitoring.
Antenna and Microphone Impedance
- The antenna impedance on the Kenwood FT-690S is 50 ohms without the antenna tuner, and 20 to 150 ohms with the antenna tuner. The microphone impedance is 600 ohms.
Modulation
- On the Kenwood FT-690S, SSB uses balanced modulation, FM uses reactance modulation and AM uses low-level modulation.
Power
- The Kenwood FT-690S requires 12 to 16 VDC with 13.8 VDC reference. Its grounding is negative. The current drain is 2A when in receive mode with no input signal, and 20.5A when in transmit mode. The output power without the antenna of SSB, CW, FSK and FM is 20 to 100 watts, and the output power without the antenna of AM is 10 to 40 watts.
Frequency Range
- The Kenwood FT-690S's frequency range is 1.8 to 2.0 MHz in the 160m band, 3.5 to 4.0 MHz in the 80m band, 7.0 to 7.3 MHz in the 40m band, 10.1 to 10.15 MHz in the 30m band, 14.0 to 14.35 MHz in the 20m band, 18.068 to 18.168 Mhz in the 17m band, 21.0 to 21.45 MHz in the 15m band, 24.89 to 24.99 MHz in the 12m band, 28.0 to 29.7 MHz in the 10m band, and 50.0 to 54.0 MHz in the 6m band.
