Legacy: No Longer Valid: The "Parrot" TG (ID#: 3153191) will soon be active on Time Slot 1;
the Parrot is a store-n-forward device that enables
checking your audio or confirming that your repeater is on the network
and operating properly. Add this TG on TS1 when next mucking
around with CPS.
With the use of c-Bridges and more users having direct access to multiple
IPSC networks, it is ever more critical that we all be using the correct
setting in our subscriber radios. This
includes an assigned ID via the
N6DVA/DMR/MARC database, 90 second messaging delay, compressed
UDP Data settings and the correct talkgroup ID's on the correct time
slots to mention a few.

Dayton and London Zones Added to Sample
The zones are San Diego, Los Angeles, London and
Dayton along with sample zones for FRS and GMRS.
the plug also has Rx Groups and Scan Lists.
Each TG name now has the repeater suffix added to aid in adding/deleting
modes in the Scan Lists.
Comm 1 and Comm 2 are now 2 different Talkgroups
The Comm 1 Talkgroup ID is:
and the Comm 2 Talkgroup ID is:
Comm 1 is for TS1 use only and Comm 2 is for TS2 use only. We
initially only had a single Comm Talkgroup and it was used on both Time
Slots. But that has changed to allow determination of which TS is
active when a user is Tx'ing on a "Comm" Talkgroup. Roundtable
and EchoLink are used the same way though obviously not "routinely" used
on Time Slot 2. The ID numbers are simply an increment of 1 for all
3 new Talkgroups. The latest User
Sample Codeplug already has these changes made. The 2-19-2010
Tip is now out of date.
Latest Codeplug now for XPR-6500
This codeplug now includes the new Comm 2,
Roundtable 2, and TRBO-Link 2 (aka EchoLink) modes and complete Zones with
the new modes for San Diego and Los Angeles repeaters. It contains
more than 76 Aliases in the Contact List. While not necessary to
immediately update your plugs, it should be on your list of things to get
done, especially if you want the most access to the system.

EchoLink Possibilities / Discussion
Randy, WB0VHB, tossed out the idea of connecting an
EchoLink station to his TRBO control radio (4300) and restricting or
whitelisting it to select users only. The audio quality would be
very high and this would greatly expand our "coverage area". Here's
the concept in more detail.
Latest User's Codeplug now has LA and SD Zones
I have programmed the Sample User's Codeplug with zones for both San Diego and Los Angeles
repeaters and have removed my zone. It includes Rx and Scan groups
to match. If you have V.01.06 6550 firmware, then you can clone your
radio with this plug. Always better to clip n paste though to be
extra careful. As always, it has GMRS and FRS zones at no extra cost
to you the user member of TRBO-6. ;-)
Talkgroup Discovery and Change
Gary, N6LRV suggested a way to enable our display
radios to show the Time Slot while a user is talking. This is very
handy when making use of Rx and Scan Groups, as you don't necessarily know
which Time Slot a user may be talking on when looking at the display.
It requires creating a new TG for TS2 for each of Comm and Roundltable,
updating the modes. The Users
Codeplug has been updated. This works well on the non-display
Need an Out-of-Band Hack for your T-Split Radios?
Snatched this info off the net and will get it
posted soon. I've done 2 T-Split radios so far, the 6550 worked perfectly, the
4550 has a hitch (but makes a nice receiver out of band, no harm done to
the radio). Out of Band Mod (file
removed as Mom got a bit testy about it)
2-19-2010: Why "Comm"
rather than "ALL Call" on TS1
and "All Call" are the only talkgroups allowed on Time Slot 1, with "Comm"
being the preferred talkgroup, All Call only if you don't have "Comm".
The "All Call" talkgroup has unique properties that
over-rides selective listening capabilities programmed into other user's
modes (channels). "All Call" also over-rides the settings of "Rx
Groups" to do it's selective work. An analogy would be making
every channel a "Priority" in a cheap scanner, simulcasting or turning off PL decode in a receiver and
putting it into "carrier squelch". "All Call" is the only talkgroup
that enables a user to over-ride everyone elses radio settings. It
was designed to be much like field supervisor's channel to all the troops.
For these reasons, the "Comm" talkgroup was created
as a replacement for All Call and the default "1" talkgroup in a new
unprogrammed radio. So ideally "Comm" should be used to replace "All
Call" on Time Slot 1. "All Call" should NOT be used on Time Slot 2
if your local repeater has Time Slot 2 on the IPSC network. See:
Repeater List to learn if
your local repeater has network traffic on Time Slot 2.
If you do not have "Comm" in your radio, then "All Call"
is permitted for now but make an effort to have "Comm" added to your
radio. The Comm talkgroup ID is:
BTW, if you in your plug, add "Roundtable" also. It is a spare
talkgroup, no need to add a mode for Roundtable if you don't wish to.
So simply add the talkgroup now, for use in the future. The
"Roundtable" talkgroup ID is:
2-19-2010: I'm a new user,
so talk! ;-)
That's rather much it. If you just got your
TRBO radio up on the network, the best way is simply come up on the
air and find someone to talk to. Ask questions and get your feet
wet. Everyone was new at one time or another. Just do it.
2-19-2010: Hot Audio / Mic Gain
Some radios are hot, some mics are hot and some
users speak loudly or close to the mic. Digital processing is more
sensitive to extremes, both high and low. As a general rule, not
knowing anything about your radio, try 4-6" away from your mouth at a 45
We have found the touch tone mics to be very hot.
Use them a foot away from your mouth. Base mics are typical of the
analog, you can hear a mouse squeak from across the room but 1-2 feet or so
from your mouth is fine using a normal voice.
People tend to speak louder when on a cell phone,
many do the same on TRBO. It doesn't help and certain voice
characteristics and wind noise cause the Vocoder to do nasty things.
The most annoying is Super Loud burst of noise on the first syllable or
word. So try to speak softly and optionally, carry that big stick.
CPS programming has some capability of dealing with
voice ranges but we have not fully tested the "best" setting as yet.
Please enable AGC on digital mode for now.
