1) Go to Scan
Lists and create 1 new scan list called "z RX & Scan". Uncheck
Talkback so you don't Tx on the non-selected mode inadvertently.
Leave the scan list blank for now.
Note: the "z and a space"
before RX & Scan will enable sorting this scan list to the
bottom of the scan list if you so choose.
2) Go into your
Rx Groups and create a 4 new groups labeled "zDCI1 TS1a & Scan",
"zDCI1 TS1b & Scan", "zDCI1 TS2a & Scan" and
lastly, "zDCI1 TS2b & Scan".
Note: the "z" before "DCI1
TS1a & Scan" and the other 3 Rx Groups will enable sorting this
scan list to the bottom of the scan list if you so choose.
You may use any talkgroup, DCI 1 was chosen for the USA
codeplug. It doesn't matter as Tx is unimportant.
Populate all your
more important TS1 talkgroups into the "zDCI1 TS1a & Scan"
Rx Group. Then populate the next most important TS1
talkgroups into "zDCI1 TS1b & Scan". Repeat for the
TS 2 talkgroup into the 3rd and 4th Rx Groups. If you need
more talkgroups in excess of the 60 supported here, simply
create a TS1c and TS2c set of Rx Groups and fill them with you
additional talkgroups. You can also put your highest
priority talkgroups into each of the Rx Groups lists so that
they are sampled more frequently as the radio is scanning.
3) Create a new
zone in your codeplug called "z Rx & Scan". It is optional
to create a new zone but it's prudent not to muck in a working
zone until you know you know you have this all working
correctly. You will not use this zone per se but the Rx
Groups associated with the modes in these zone are the key to
4) Create 4
modes in this zone labeled: "DCI1 TS1a & Scan", "DCI1 TS1b &
Scan", "DCI1 TS2a & Scan" and "DCI1 TS2b & Scan". Use your
home or main repeater info but make sure that all modes use scan
list: "z Rx & Scan". In each of the 4 modes, place the
matching Rx Group list in the "group list" field on the left
side in CPS under RX. Check the auto-scan box though not
critical. We suggest you make this a "RX only" as you
really should never need to transmit or really never even select
this zone (trust us on this for now) so any TX contact is
unimportant. Remember, the purpose of this effort is to
listen, not necessarily transmit. That comes later.
5) Go back to
your Scan List and now populate it with the 4 modes created in
your "z Rx and Scan" zone. If you have a preference of
which TS of the 2 modes, then set the priority also in the scan
list. We suggest you set you set your first and second
modes as Priority 1 and 2 if you have any priority talkgroup
preference, but it is optional.
6) Now you can make use
of all of the above work...by simply creating 1 mode in any zone
of your choice. Even a new mode is optional but what you
should do is place the "z Rx and Scan" scan list into this new
mode or existing mode. Make that mode an auto-scan mode as
this is the key to listening to 30 plus talkgroups. Label
your existing mode with extra characters such as "AllScan" or "AllRx"
at the end of the label so you know this is the super duper
auto-scan listener mode.
That's it...now you can, from
any zone, listen to everything without even hitting a scan
button. 30, 60 or 90 talk groups is just a click of the
selector (HT) away. If you see your repeater is active but
don't hear anything, just select your mode that has this scan
list in it and it will auto scan.
Optional: if you
wish to create a priority for the RX groups then you can further
create more Rx Groups based on priority and timeslot. But
as you add more modes to your scan list you degrade the speed of
the scan due to it's channel sampling. Scanning only 2
modes has essentially eliminated any clipping of the beginning
of a transmission so 3 or 4 modes still will pack much benefit.
Optional: If you
wish to further refine you list of talkgroups to a smaller
subset, then simply create more Rx groups and only add the more
important talkgroups. Create another scan list for this
subset of mode(s). Make the mode label descriptive of it's purpose so
you can easily keep track as you spin the mode selector.
Cons: If you use
nuisance delete, you will lock out up to 15 talkgroups in one
fell swoop unlike just a single mode which is normally done when
using nuisance delete.
Let use know how you fair on
this rather unusual implementation of Scan using RX groups.
