KFS 594 CONTROL DISPLAY UNIT
The KFS 594 (Figure 2-2) provides the pilot with access to 19 pro-
grammable channels plus a full 280,000 operating frequencies in the
2.0 to 29.9999 MHz range. In addition, all 245 ITU maritime radiotele-
phone network (public correspondence) channels have been stored
in nonvolatile memory along with the appropriately paired transmit
and receive frequencies. Thus, to call up a radiotelephone channel,
the pilot need only select “423” for WOM in Ft. Lauderdale, Fla., for
example, rather than having to program 4425.6 kHz as the transmit
frequency and 4131.2 kHz as the receive frequency (see WOM chan-
nel/frequency chart, Figure 7-3). The KFS 594 is a miniature Gold
Crown III style control display unit which uses electronic gas dis-
charge readouts to display frequency and channel information. All
necessary controls for operation of the KHF 950/990 system, includ-
ing programming of all preset channels, are on the KFS 594.
The 19 channels can be easily programmed by the pilot on the
ground or in the air, and the nonvolatile memory stores this informa-
tion and the 245 ITU maritime radiotelephone channels even when
the system is turned off.
