| The
new solid state Drake FS-4 Synthesizer opens the door to a new world of continuous-tuning
short wave. Combines synthesized general coverage flexibility with the selectivity,
stability, frequency readout and reliability of the DRAKE R-4C or SPR-4 Receivers.
 | Interfaces with all R-4 series
receivers and T-4X series transmitters.(R-4, R-4A, R-4B, R-4C. SPR-4, T-4, T-4X, T-4XB and
T-4XC), without modification |
| MHz range IS set
on FS-4. With kHz readout taken from receiver dial |
| Complete general coverage-no range
crystals to buy. |
| T-4/T-4X series transmitters
transceiver on any FS-4 frequency, when used with R-4 series receivers |
| Readout 1 kHz with Drake
PT0.

R-4C/FS-4 :
| Passband Tuning, Notch Filter.
optional Selectable 8-pole Crystal Filter for optimum selectivity |

Note from Ramon Klein
:
Hello,
I was visiting the museum and noted that the FS-4 information didn't mention that it can be
used on the 2-C receiver as well. The only changes required for the FS-4 to work with the
SPR-4, 2-C and R-4 receivers is the crystal in the FS-4.
R-4 and T-4X 9.6
Mhz crystal
SPR-4
9.59
Mhz crystal
2-C
9.5
Mhz crystal and add 7 Mhz. to FS-4 readout for proper frequency.
