Note on 93 kHz Frequency Use
The SR-60 offers two 93 kHz frequencies for Line Tracing.
The default 93 kHz frequency has an actual cycle count of
93,623 cycles per second.
But some older transmitters use a different value for the
nominal 93 kHz frequency, 93,696 cycles per second. This
is found in the SR-60 listed as "93k-B".
If you find that your transmitter signal at 93 kHz cannot be de-
tected by the SR-60, set the locator's frequency to 93-B kHz,
which is set to the older value. Both 93 and 93-B frequencies
can be found under the Line Trace category of the Frequency
Selection sub-menu.
Sounds of the SR-60
The sound level is driven by the proximity to the target. The clos-
er to the target, the higher the sound pitch will be. A rising tone
indicates increasing signal.
In Active Line Trace or Passive Line Trace mode, sound is on one
continuous curve and does not re-scale.
In Line Tracing modes, the default distortion response also acti-
vates an audio signal proportionate to the distortion in the de-
tected field. When there is no distortion present, the sound of
the SR-60 is a clear warbling sound when on the left side of the
detected field, with a slight click added when on the right side
of the detected field. If distortion is detected a sound similar to
AM radio static sound can be heard, which gets stronger as the
degree of distortion increases, similar to the unfocusing that sig-
nals distortion visually around the Tracing Line. If the distortion
response feature is disabled, the static sound does not occur.
In Sonde Mode, if the sound level reaches its highest point, it
will "re-scale" to a medium level and continue signaling from the
new starting point.
In Sonde Mode, the pitch will "ratchet" upward. That is, it will rise
and then re-scale (fall) in pitch while approaching the Sonde.
Moving away from the Sonde, it will drop to a lower pitch and re-
main there as long as one moves away from the Sonde. Moving
back toward the Sonde again it will resume rising in steps start-
ing from the level it had reached previously. This serves as an
indication when the locator receiver is getting closer or further
away from the Sonde.
