CS700 MotoTrbo DMR - Scan list modification

The past week I have been reading over and over the Motorola Planning Guide (500 some pages) and been playing around to improve my scanlist to speed it up and other features on my radio.

First I thought I would just reduce the number of channels in my scan list, down to 7 TG plus one simplex. That was a bit better but at the cost of not scanning 8 not so busy TG.

No big deal, by the looks on Netwatch and CAN-TBRO last heard, they are rarely used, or rarely UA in Ontario.  ( test, DCI,MIT,NB,QC,MB,AB,BC )

So Monday eve while having dinner at a restaurant and reading again that planning guide on my iPad since this was bugging me and was telling Victor and Walter about my testing minutes before my dinner.   Then Bingo !! there it was in the guide.. use groups in the scanlist instead of channels.. So when I went home Monday eve I tried it and so far so good.   The results were Fast ! the only 3 items in my scan list. TS1, TS2 and one digital simplex; it could be 2 items but I like to have a simplex included.


Create the following Rx Group lists
TS1 with WW, EN, NA, CDN, DCI, MIT, TAC310, Test
TS2 with QC, ON, MB, AB, BC, NB, Local

Edited all the channels for the Toronto repeater or more for your testing..( Raglan, Hamilton..)
so for every channel that is on TimeSlot 1 it's RX Group is TS1 and every channel on TimeSlot 2 it's RX Group is TS2. 

Next step is to modify your scan list for that repeater....
Remove all channels in that scan list, except one channel from TS1 & one from TS2 and a digital simplex if you care.
So your scan list can have NA, Local channels for that repeater and Simplex channel.

Since NA listens to all TG on TS1 and Local listens to all TG on TS2 you will be covered for all TG just by scanning those two channels and faster than scanning 15-16 channels.


So for past three days it has worked fine; scanning is fast and even when the unit is not scanning I know and hear when the TS I am sitting on is busy, without having to key up and get the "repeater busy" tone. So now I just wait for the other TG on same TS to finish their QSO or a break to key up my TG on that TS. Or even sometimes it saved me from keying up my TG because now I knew the person I was trying to reach was on different TG same TS without scanning.

2 versions of the scanlist ::

Thanks...but here is the latest.. 2 versions of the scanlist 
( QSO between Don, Victor and myself last night) 

Per our qso last night, and your concerns with listening to one TG and hearing all other TG on same TS... I came up with a version 2 just to address your concerns and still keep fast scan of only 2 or 3 channels. Your comments... 
BTW I officially call these two version of scan list (after a french saying) "Never miss a fart scanlist" lol

====  Version 1  ====

Create the following Rx Group lists
TS1 with WW, EN, NA, CDN, DCI, MIT, TAC310, Test
TS2 with QC, ON, MB, AB, BC, NB, Local

Edited all the channels for the Toronto repeater or more for your testing..( Raglan, Hamilton..)
so for every channel that is on TimeSlot 1 it's RX Group is TS1 and every channel on TimeSlot 2 it's RX Group is TS2. 

Next step is to modify your scan list for that repeater(s)....
Remove all channels in that scan list, except one channel from TS1 & one from TS2 and a digital simplex if you care.
So your scan list can have NA, Local channels for that repeater and a Simplex channel.

Since NA listens to all TG on TS1 and Local listens to all TG on TS2 you will be covered for all TG just by scanning those two channels and faster than scanning 15-16 channels.
Also by just sitting on one channel you can monitor ( not scan ) all other TG on the same TS;
no extra battery power used for monitoring vs scanning. But you still have to scan to catch an active TG on either TS.


====  Version 2  ====
( Only assign new Rx Group to two channels not all channels, TEST for TS1 and QC for TS2)

Create the following Rx Group lists
TS1 with WW, EN, NA, CDN, DCI, MIT, TAC310, Test
TS2 with QC, ON, MB, AB, BC, NB, Local

Edited ONLY 2 channels for the Toronto repeater or more for your testing..( Raglan, Hamilton..)
TEST channel that is on TimeSlot 1 it's RX Group is TS1 and QC channel on TimeSlot 2 it's RX Group is TS2. 

Next step is to modify your scan list for that repeater(s)...
Remove all channels in that scan list, except TEST & QC.
So your scan list can have TEST and QC channels for that repeater and a Simplex channel.

Since TEST listens to all TG on TS1 and QC listens to all TG on TS2 you will be covered for all TG just by scanning those two channels and faster than scanning 15-16 channels.
You cannot monitor other TG on same TS unless you are on channel TEST or QC, you must use scan and more battery power to catch an active TG

I picked those two channels, since I figured they would not be used for QSOs or english QSOs.
