What do CTCSS and DCS means


CTCSS is a subaudio (<300Hz) tone that is broadcast when you transmit on a radio. If another radio is set to receive that tone, then the squelch will open and he will hear your transmission. Having said that, any other radio that does not have CTCSS set at all will also hear your transmission, so all it does is for the receiver to hear less of others talking. DCS is the same except that CTCSS sends out a continuous tone, DCS sends out a string of tones. This allows more "channels" to be allocated, but still ,everyone is using the same frequency

Stuck on rx mode


Rx is an abbreviation for receive. (Tx is transmit) There are a variety of reasons a radio will be "stuck" in Rx:
1) Another radio in the group is stuck in transmit and you cannot reply if your radio is receiving the other radios transmission.
2) Your radio is programmed for Rx only.
3) Your radio has a Tx problem such as a bad mic, or something covering the mic opening.
4) Your battery is low or bad. It takes more energy to Tx than to Rx.

Best regards.

look in the battery compartment for a series of tiny switches under the batteries.. these switches must be identical for each radio..it puts them on the same frequency..then select channels with no interference..retry radios..

How can this problem be fixed?


Not sure what you are working with, but most radios do not transmit and receive simultaneously.

Two sets of Motorola Walki Talki radios will not communicate.


In addition to the channel and privacy codes, some Motorola two-way radios have a feature called Eavesdrop Reducer where you have 3 scramble settings available; perhaps you have this set on one of sets of radios but not the other. It should be something like that because otherwise there is no reason that by setting the radios to the same channel and privacy code they wouldn't be able to send/receive to each other.

Radio will not send


It is possible your Code for transmit is different than your Code for receive. Cobra makes so many models, you are not giving enough information. Also, Transmit takes a LOT of power, so even if everything is setup, if your batts are weak or old, the radio will receive, but not transmit. Also check your antenna, make sure it is tight and NEVER transmit without an antenna. Yes, all lights will work even with old batteries.

I cannot set QT filltering on..why?


Here are the instructions from the manual:

To transmit to a radio that has QT noise filtering turned on:

1. Select the same channel and Interference Eliminator Code as the other radio.

2. Press 'musical note' button to send a call tone. This allows your voice to pass through the QT

noise filter on the receiving radio.

3. Press the PTT and speak normally.

Note: If you skip step 2, the beginning of your message may not be heard on

the receiving radio.

For a 30-second period, starting after the last transmission, all transmissions
received on the selected channel and code will pass through the QT noise filter.

Also, your QT filtering will NOT work if you are in scan mode.

My XU2100 XTN series 2 Way radio is not working. Not receiving or sending transmissions to the other two radios. It is fully charged. It does not make an audible "beep" when you turn it on. ...


Your radio is likely in need of repair. Flat rate repair for this model usually runs around $69. The fact it does not give you the initialization beep indicates it is more than a frequency problem. Then coupled with you do not have transmit or receive, this sounds like you have more of a problem than a bad speaker.

A few things to check before sending it for repair would be:
1) Swap the battery with a known good unit to see if your battery is bad/low and doesn't have enough power to function the radio fully.
2) Check your frequency and code to see if it matches your other units. This is in the upper right corner of the screen shortly after turning the radio on.
3) Check your mic opening in the grill of the radio to be certain it is not covered or free from debris.

If these any of these three items do not solve the problem, you should send your radio for repair.

Best regards.

Motorola and Kenwood compatibility....


Hello!! First of all, any radio in the right frequency will work with any other, to work just need the following features: -Frequency, 154.700 which is correct as you said. - the Squelch code, this could be PL or DPL. The XV2100 has a table of codes that you can try, as you dont know this code form the Kenwood, you will need to check one by one. If you have the chance to send the Kenwood to some to "Read" the radio parameters( freq.,Code, ETc) you can look those parameters on the XV. Hope this can help, any comments [email protected] Good Luck
