What does CTCSS mean on a walkie talkie?
Continuous Tone Coded Squelch System
In conventional radio, one of the most used and sometimes misunderstood features is CTCSS, which stands for Continuous Tone Coded Squelch System.
What does R tone mean?
The R-tone is a receive tone. In lots of areas, there is interfearance from foreign sources. We have this in Big Bear, or used to when I lived there. The repeater then will transmit an outgoing pre-tone an dusers can set their radio to only play sounds containing those tones.
How do CTCSS tones work?
CTCSS is a system whereby a (not really) sub-audible tone is encoded into the transmit audio of a radio and a receiver on another radio on that frequency will only open up (decode) when it picks up that specific tone. These are where CTCSS really shines.
How do I turn off CTCSS on my walkie talkie?
on. Press the button for over 3 seconds to turn the radio off. Volume : Press the button to increase the volume, and press the button to decrease the volume during normal operation. Talking and Listening : To communicate, all radios in your group must be set to the same channel and CTCSS Code.
How to use CTCSS / DCS / cross tone-2?
CTCSS/ DCS/ CROSS TONE – 2 CTCSS FREQUENCY SCAN This function scans through all CTCSS frequencies to identify the incoming CTCSS frequency on a received signal. You may find this useful when you cannot recall the CTCSS frequency that the other persons in your group are using. 1 Press [TONE] 2 times to activate the CTCSS function.
What are the features of a Kenwood th-d72a transceiver?
The models listed below are covered by this manual. TH-D72A:144/440 MHz FM Dual Bander (The Americas) TH-D72E: 144/430 MHz FM Dual Bander (Europe) FEATURES This transceiver has the following main features: † A built-in GPS receiver unit. † A built-in 5000 point GPS Logger. † A built-in TNC which conforms to the AX.25 protocol.
Can a th-d72a be used as a repeater?
This means, say, that you can arrange to have both the call channel and local channel, or the repeater channel and local channel, on the same VHF or UHF band. The KENWOOD Sky Command System II allows you to use the TH-D72A for remote access to KENWOOD’s designated HF radios.
How does th-d72a work on a HF radio?
Operating as the Commander, your TH-D72A transmits control signals to the Transporter, which also relays your voice to the HF radio. In return, HF signals are transmitted back to the Commander. This system allows you to transmit and receive HF signals, set frequencies (with LCD confi rmation), switch memory channels, and much more – all .
