FP707 Power Supply.
Yaesu FC-707 FC707 Aerial Antenna Tuner.
The Yaesu FT-707 is an all solid state transceiver for the HF amateur bands.
Featuring coverage of 80 through 10 meters, the FT-707 is designed for operation on SSB. CW and AM.
Nominal power output is 100 watts on SSB and CW. and 50 watts on AM.
The extremely compact size of the FT-707 makes this model particularly well suited for mobile or vacation use.
The receiver section includes a Schottky barrier diode ring module for excellent performance in the presence of strong signals.
A very-low-noise premix local oscillator circuit is used, which further contributes to optimum receiver performance.
Also included in the receiver is
variable IF bandwidth, using two 8 pole IF filters, allowing continuously variable adjustment of the
IF bandwidth, from 300 Hz to 2.4 kHz.
Six pole filters of 600 Hz and 350 Hz bandwidth (
- 6 dB) are available for contest and DX operators, with selection of the SSB filter or CW filter available on the CW mode.
The transmitter side features two rugged bipolar transistors with multiple protection in the final amplifier stage, with
band switched low pass filter networks.
Digital plus analog display of the operating frequency is provided.
The front panel meter consists of a string of bright discrete LEDs, for
monitoring of the received signal strength, relative power output. and the transmit ALC level.
Available options for the FT-707 include the FP-707 AC Power Supply, which provides the 13.3
volts DC required by the FT-707.
The FV-707DM external VFO, which provides twelve memory channels using a
synthesizer which allows scanning in 10 Hz steps.
The aerial tuner unit FC-707 Antenna Coupler.
Mounting bracket for mobile use.
