Priority Sampling Method
RSS LOCATION
DEFINITION
Determines the way in which the priority channel(s) is checked for activity during
a “lookback” from an active second priority or non-priority channel.
DEFAULT/CHOICES Default: Continuous
Choices:
Continuous
1-SHOT PL
Continuous
Continuous always performs a complete check of the channel. If no
carrier is present, then the sampling ends. If a carrier is present, a
full PL check is made on each sample.
1-Shot PL
For 1-Shot PL, once a carrier is seen, a full PL sample is only done
once until a sample is seen with no carrier present (that is, a carrier
“break”). See PIX.
RECOMMENDATIONS
Almost always use Continuous. Use 1-Shot PL to reduce hole size on shared chan-
nels (for example, community repeaters, timeouts). Your best advantage occurs if
you reduce the priority sampling rate when using 1-Shot PL.
WARNINGS
There is a risk that messages will be lost on the priority channel. Use Continuous
for critical priority channels (public safety, etc.).
IMPORTANT NOTE
Best performance of 1-Shot PL is attained on a well-controlled channel, since a
wide carrier break is needed to reduce lost priority activity. Your repeater panel
may have an access timer that will help. Busy Channel Lockout on all radios will
help.
