I have the uniden 1558-CK2 walkie Takies for my kids and ond of the radios has the "rx" symbol on the screen lit on and the radio will not transmit to the other radio. what can I do to resolve this issue

Adjust your SQUELCH control or setting so that the noise disappears. The RX indicator will go out.

Sounds like the PL tone is set on the two, with different tones. Go to the menu, find the tone screen, and turn off the tone (or set them all to the same tone). That should fix the problem!

This model has a "Monitor Mode" feature that allows you to listen for weak signals on the current channel at the press of a key.
1.) To turn ON monitor mode:
Press and hold the volume/monitor up or down key. The rx icon will blink.

2.) To turn OFF monitor mode:
Press the volume/monitor up or down key. The rx icon will stop blinking.

Check your batteries. Static can be a sign of a bad or low battery. Swap batteries between the units to see if the problem moves to another radio.
Also, check your antenna and antenna connection.
Best regards.

Hi Laura,

When you see the Rx sign on the screen, it indicates that someone else is transmitting (Tx) on the channel, this is also caused by "BOOF HEADS" who like doing nothing more than dropping carriers by holding down their PTT button during a conversation, something that happens a lot on CB and without a doubt on FRS radios.

There is no problem in your radio, it's Just someone else probably dropping a carrier as per above.

Not much can be done about this problem, No License, No Joy.

The fact you can hear the other person over the screach indicates to me that I am right, and your radio is fine.

I hope this clears up your query.

Warm Regards,
Peter

Be sure the tone codes and channel frequencies are set identically on both units.

• You need to get your radio out of monitor mode. To do this just pres the "mon" button for two seconds. Monitor allows you to just listen on that frequency and also receives weaker than normal transmissions while in "monitor" mode as well.

The 21-1936 was made for Radio Shack by Uniden and is identical to the Uniden GMR-1038-2
The Uniden version of the manual is available HERE

Sounds like the radio was subjected to electrostatic discharge. If you have your manual, and it describes a way to do a "master reset" on the radio, follow the instructions. This usually involves pushing down on one key while turning the radio on. Otherwise you have to find a licensed dealer for factory service, as there is no way to repair the radio yourself. The use of surface mount technology still confuses many Techs unless they have been to a company's two or three week seminars.

Howdy from South Texas and Merry Christmas;

While I did not see any radios with the model number you mentioned here is a lik to the Uder Manuals on Midlands website. http://www.midlandradio.com/owners_manuals.asp
