Information
1-1. GENERAL DESCRIPTION.
The FS-4 is a frequency synthesizer developed for use with
the Drake Company “4” line equipment. (R-4 series, T-4X
series and SPR-4.) The FS-4 plugs into an unused auxiliary
crystal socket in the rear of the receiver or transmitter,
and will supply the various injection signals to the
equipment and allows continuous coverage without utilizing
the accessory crystals.
The frequency readout on the FS4 displays the received
frequency band, and to this is added the frequency readout
of the receiver “PTO” to obtain the correct received frequency.
The FS-4 supplies all the crystal oscillator injection
signals for the R-4 series and T-4X series in 0.5 MHz steps
from 11.1 through 40.6 MHz, and the readout is direct. An
accessory kit is available to provide proper injection
signals for the SPR-4 receiver.
The FS-4 can be used with the 2-C type receiver over the
frequency range of 7 to 30 MHz. When used with the 2-C
receiver, the FS-4 frequency readout is not direct, and a
correction factor of “7 MHz” must be added to the FS-4
readout to obtain the correct operating frequency. A special
accessory kit is necessary to modify the FS-4 for use with
the 2-C receiver.
