QUICK TALK
TM
PROGRAMMABLE FEATURES.................................................................................................................................
Input Screen
The Input Screen is used to uniquely program the behavior of each input.
FIG-2: Programmer Input Screen
Frequency Table
To match other RITRON radios, the owner can select from a table of transmit
frequencies. Simply “read-out” the Frequency Code of your RITRON
portable, mobile or base radio and enter the same code when programming
the Quick TalkTM. Note that all RQT-151 and RQT-451 table frequencies
operate in narrow band mode (12.5 kHz).
Transmit Frequency
Once you have selected a code from the Frequency Table the actual transmit
frequency will appear here. If your operating frequency does not appear on
the Frequency Table list, a licensed radio service technician will be able to
enter other frequencies within the radio’s operating band.
To identify your assigned frequency:
• Read-out the Frequency Code of the RITRON radio you intend to use with
the Quick TalkTM.
• Check for a corresponding color dot on the radio you intend to use with
the Quick TalkTM.
• Locate a label identifying the receiver frequency in megahertz (MHz).
• Your assigned frequency is shown on your FCC Station License.
• Call your radio dealer or Ritron for help if you cannot determine your
radio’s receiver frequency.
• The original factory-programmed transmitter frequency of your Quick
TalkTM is marked on the outside of the shipping box.
QC or DQC Code
Select from a list of QC and DQC Codes to transmit subaudible squelch
tones for interference elimination.
The Quick TalkTM radio transmitter is compatible with two standard
communications industry sub-audible signaling formats: QC (Quiet Call®
Interference Eliminator), and DQC (Digital Quiet CallTM Interference
Eliminator). Both Quiet Call formats unlock receivers programmed to require
these codes -- they screen out interference from
other radio systems operating on your transmit
frequency.
QC Quiet Call
®
is Ritron’s trade name for what
the communications industry calls sub-audible
(below the range of human hearing) tone
squelch, or CTCSS (Continuous Tone Coded
Subaudible Squelch).
DQC Digital Quiet Call
TM
is Ritron’s digital coded
squelch, and works the same as QC, except it is
a digital code that is transmitted with the voice
messages.
To identify your QC or DQC tone:
• Read-out the Tone Code of the RITRON
radio you intend to use with the Quick
Talk
TM
.
• Refer to your radio manual.
• Contact your radio dealer or Ritron if you are
unsure about this issue.
DQC Invert
The DQC Digital Quiet Call
TM
code can be
inverted for systems that require inversion.
Compand
Some two-way radios have a feature referred to
as “companding”. It is a way of eliminating
background hiss or noise, making the radio
sound clearer. “Companding” is a combination of
audio “compression” in the transmitter and audio
“expanding” in the receiver. The Quick Talk
TM
can be programmed for audio compression. To
determine if your existing 2-way radios are using
the Companding feature, you can check the
radio’s User Manual, contact your radio dealer,
or call Ritron for help.
If you are unable to determine if your portable
radio uses the companding feature, we suggest
the following:
1. Leave the radio in the factory default setting
with no companding.
2. Activate the transmitter of the Quick Talk
TM
and listen to the message from your
portable radio. If the received audio is
acceptable, you should not need to set the
Quick Talk
TM
for companding.
TX Alert Tone
By default, the RQT will transmit an alert tone
before each voice message transmission. This
feature can be disabled via the PC programmer.
