Solid state 80, 40, 20, 15 and 10-meter transceiver suitable for fixed and for mobile CW / SSB operation. 10 Watts power output, single conversion receiver with 9 MHz IF, good sensitivity and SSB selectivity. The VFO frequency is 5–5.5 MHz so that the receiver covers the 80-meter band directly. The VFO output is mixed with appropriate crystal oscillator for the other bands. Ideated in Japan, year of introduction 1976.

FT-7 series :

The Yaesu FT-7 QRP transceiver, also imported in Europe by the Swiss firm Sommerkamp and sold as Sommerkamp FT-7, was very small for its time. The 10-meter coverage was limited to a single 500 kHz segment, from 28.5 to 29 MHz. As option the VF-7 separate VFO.

The FT-7B upgraded transceiver, also imported in Europe by the Swiss firm Sommerkamp and sold as Sommerkamp FT-7B, with higher power output was released three years later. The 10-meter coverage was fully extended to four 500 kHz segments, from 28 to 29.9 MHz. As option the YC-7B digital readout frequency counter.

FT-7 main tuning dial :

Coarse frequency determination is made by referring to the lower of the two analog dials. The lower one has numerical calibrations every 100 kHz and a calibration mark every 50 kHz. The upper dial has numerical calibrations every 10 kHz, with resolution marks to 1 kHz.

Yaesu FT-7 main tuning dial frequency readout

Frequency readout on all bands is determined by adding the frequency on the main tuning dial to the frequency of the lower band edge. For 40m, 20m, 15m, and 10m band segments A and C, the band edge begins at 000 (for example 7000 kHz on 40m). On 80m and 10m band segments B and D, the lower band edge begins with 500 (for example, 28500 kHz on 10m / segment B). Thus, a reading of 074 on the main tuning dial will represent 3574 kHz, 7074 kHz, 21074 kHz, 28074 kHz, 28574 kHz, 29074 kHz, or 29574 kHz, depending on the position of the band switch.
