Extended Functions - Kenwood R-5000 User Handbook Manual

When used with the Scan Busy Stop modification (see page 5), this modification makes
the scan function in the R-5000 much more effective. Time Operated Scan stops on an active
channel only for 5 seconds, then resumes scanning. This means you would miss the rest of the
transmission if it last more than 5 seconds. Carrier Operated Scan will not resume scanning
until the signal goes away, much like the scanners people use to listen to police and fire calls.
With this modification you won't miss a thing!

EXTENDED FUNCTIONS

The R-5000 has several option jumpers that allow you to change how the receiver
functions. These jumpers are vertically mounted diodes located on the Control PWB attached to
the front panel. The diodes are labeled D65 to D69 and D72. Figure 2 shows the location of
these diodes.
Frequency Resolution
Diode D65 controls the resolution of the frequency display readout. The standard resolution
is 10 Hz. With D65 cut, the display resolution is 100 Hz. The receiver still tunes in 10 Hz
increments. I don't see any reason to decrease the display resolution, so this option has
very limited applications.
Mode Key Read Back
Diode D66 controls the read-back function of the mode keys. The standard function causes
the receiver to generate the Morse code letter corresponding to each mode when a mode
key is pressed. Visually impaired operators can then hear which mode they select. With
D66 cut, the receiver generates a single beep to acknowledge a mode key press. Most
operators get annoyed with the constant beeping, so you can cut this diode and save your
sanity. The Adjustment section details how to turn off the beeping completely or adjust the
volume level.
