Scanning
The K3's scanning features let the K3 tune any band
segment continuously, with or withoutthe receiver
muted (Some bands may be excluded from scanning for
regulatory reasons.) Scanning can be used to monitor
any portion of a band, from a 1-2 kHz range where
a station or net is expectedto appear, to an entire
band.
Sometimes a band that appears “dead” may actually
have several stations present. You can use scanning
to findthese stations for you while accomplishing
othertasks.
Scanning while muted allows the K3 to ignore
stable carriers (key-down signals with no
modulation), unmuting only when "interesting"
signals are found. Scanning with the receiver "live"
(not muted) is especially useful when listening for
weak signals on very quiet bands.
Scanning Setup
To use scanning, you first needto store the desired
tuning range in a memory. After that, you’ll be able
to simply recall the memory, then start scanning.
You can set up scanning ranges for various bands,
modes, etc.
To set up a scanning memory:
Set VFO A to the starting frequency, and VFO
B tothe ending frequency.
Select the operating mode, preamp/attenuator
settings, and filter bandwidth. Also select the
tuning rate, which affects speed of scanning.
Store this setting in any memory (pg. 16).
To start scanning:
Recall the memory using M V .
Hold SCAN to start scanning. To scan with the
receiver live (unmuted), continue to hold
SCAN until you see AF ON (about 2 seconds).
You can stop scanning by manually rotating VFO
A, tapping any switch, hitting the key or keyer, or
pressing PTT.To restart, hold SC AN.
Channel Hopping
Scanning or manuallytuning over a numbered
memory range, rather than a frequency range, is
referred to as channel hopping. This is included in
the K3 primarily for use on 60 meters, 6 meters, and
transverter bands, although it can be used on any
band.
The U.S. 60-meter channel assignments
correspond to VFO settings of 5330.5, 5346.5,
5366.5, 5371.5, and 5403.5 kHz. USB is the only
mode allowed on this band.
Memoriesto be used for channel hopping must be
consecutive, withinthe same band, and must be
assigned a text label that starts with an asterisk (*).
To set up channel hopping:
Set VFO A to the first frequency inthe intended
channel-hopping range. (VFO B does not have
to be set higherthan VFO A for channel
hoppingpurposes.)
Tap M V ,then select a memory (00-99)
using VFO A. For the five 60-meter channels,
we suggest using memories 61-65. Start with
memory 61 for 5330.5 kHz (US), or your
country’s first 60-meter allocation.
Rotate VFO B to select each memory label
position in turn as indicated by the flashing
cursor.
Use VFO A to change characters. The first
character must be an asterisk (*); other label
characters are optional.
After editing, tap M V again.
Set up all other memoriesto be used for
channel hopping.
To enable channel hopping (manually or via
scanning),tap M V , use VFO A to locate one of
the memories in the sequential range set up earlier,
then tap M V again. VFO A will now cycle
through thisrange of memories as youturn it. To
disable channel hopping, tap R ATE or F INE or
change bands.
To start channel-hop scanning, hold SC AN . You
can also use “live” scanning as mentioned at left.
