SOURCE: Push to talk problem

Hi,

If indeed radio #1 has a mic problem, this may be confirmed by trying an external speaker/microphone plugged into the accessory jack. If still a no, then its not the mic but possibly the modulator circuitry. If there is transmit audio with the external mic and hence internal mic is defective, the unit would have to be pried open and the defective component replaced. The internal mic is normally an electrofet 2-3 terminal soldered to a shielded wire and physically attached to the front plate.

Alternately, another possibility is that radio #2 has its Interference Eliminator Code enabled/activated. This is indicated by the presence of small sized digits on the top right of display. If this is the case and no similar digits are displayed in radio #1, then radio #2 will not allow any received transmission to be heard. Along the same line of reasoning, if the code is activated on both radios signified by the presence of the 2 small digits, and radio #1 has a problem with its CTCSS (code) generator, then it would also prevent reception of radio #2. A way to verify this is by deactivating/disabling the Interference Eliminator Codes on both radios.

On certain occasion, it is also possible that radio #2 has a defective speaker. You should be able to verify this by plugging in an external speaker to the accessory jack of radio #2.

Hope this be of some help/idea. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.

SOURCE: can i have my UH064sx-2 Radio activate & send when i talk into it

AFAIK, this is only possible when you have the headset plugged in. The headset allows VOX operation (voice operated transmission). If there is nothing plugged in or the handset is plugged in, the VOX setting is automatically switched off.

You can adjust the sensitivity of the mic so that it will start transmission only when a certain sound level is exceeded. There is a tiny lag between when it detects the sound and when it starts transmitting.

SOURCE: My UH043SX-2 seems to be

We have 6 of them all with the same problem. Uniden says to turn off holding down the mon and scn buttons. Then hold down the mon and scn buttons together for 20 secs. Then turn on holding down the mon and scn buttons at the same time. Then turn off and turn on again. This should clear the problem. It didn't for me so I threw them away and bought some more. I think that would have been easier than all the other stuff!

I talk on my cb no one talks back


you could have ten people talking to each other and if no one wants to talk to you then you will be talking to no one.Now if its a radio problem then I would say turn up the variable for your modulation , make sure your RF GAIN is wide open and turn your SQUELCH all the way to the left then go to different channels and ask for a radio check or have a friend drive far enough away and with his radio give you a radio check.

How do I connect Motorola Talkabout KEM-ML36100 with Uniden pmr1188?


I don't know where you are located, but I have a feeling that you are using two incompatible systems.
The PMR (Personal Mobil Radio) is build for the European market. The allocated frequencies for it's 8 channels are from 446.00625 Mhz to 446.09375 Mhz. Your Motorola is for the US market GMRS (General Mobile Radio Service) and FRS (Family Radio Service) and it's channels are allocated from 462 Mhz and 467 Mhz area.

Bottom line is, since their channels are on different frequencies, they can't talk to each other.

BTW, it would be illegal to use the European radio in the US and visa versa. You could be interferring with other radio services.

How to get maximum range


Have a fully charged good battery. Hold your radio upright, perpendicular to the ground, when transmitting. (Tilting to the side can significantly reduce range.) Wear your radio higher on your body if carrying the radio. Height and placement of antenna has much to do with good range. Talking line-of-sight in perfect conditions a portable radio will get approx. 2 mi., talking in and out of a building you may get 1/4 to 1/2 mi. Obstacles inbetween the two radios will reduce range, so each location may differ. From a mountaintop you may be able to talk many miles into a valley below. Your radio can basically talk as far as the antenna can see.

How to remove the letters RX near the battery so u can talk to another person It's a Uniden hand held receiver model-uh043sx-2


Hi Phillip,

The Rx symbol indicates that someone else is using the channel, which, (if your radio is working correctly) means you should be hearing them, if this is the case then there is nothing you can do to change that, because only one person at a time can use the channel at a time, however, as we\'re talking about CB radios, that is not always the case, dependant on the make and model of the radio in use.

In the case of your radio, not much can be done, as that is a factory default setting, so you can\'t override this without getting into the unit and risk stuffing it up period.

If you know someone in the 2-way radio game i.e,. a radio technician, or radio amateur, they could help, otherwise you can\'t do much about this.

If this is a real problem for you, then getting a bigger 5 watt radio could be an answer, as these are normally set by default to allow you to override the Rx when you Tx.

Note: Don\'t buy a Chinese made unit, as these are not reliable, nor stable units for Aussie use, I found this out when I purchased an Oricom CB... Absolute crap, cheap and nasty. Be aware of where radios are made, regardless of brand name.

I hope I have been of assistance.

Regards,
Peter

I cannot send, only recieve


Hi,

Based on your description, possibly a microphone problem. Either that or a wire is cut/open in the microphone cable. Remote possibility is the FM modulator circuitry internal to the marine radio.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Uniden 2-way rc1032


Hi, it's basically a pair of push to talk radios (You push the button on the side to talk and release to listen). As long as you set to the same channel, you should be in contact, good for quite a distance. (Their product info says 6 miles, but experience has taught me to cut it to 'bout a third). It's got so many features that you have to read the manual which is available on line @ http://www.uniden.com/pdf/GMR638-2CKom.pdf. One thing you have to remember is to set both radios to identical setting. Hope this be of some help to you. Good luck.
