Re: One radio has to be set on channel 3 other on channel...

Hi, One way this would be possible is if you have set offset/duplex operation. My understanding however is that this feature is not normally available for this model. Normally Ch3 is 462.6125 and Ch18 is 462.6250, this can either mean that one of the radio has drifted down (frequency) or the other radio up. Since both are still operational albeit the disparity in frequency, what is probably needed is a simple calibration/adjustment of the PLL/VCO's trim capacitor. Of course a frequency counter & a dummy load wattmeter is needed to perform this. I also understand that FCC requires that you be licensed to be able to adjust/calibrate. Hope this be of some help/idea. Post back should you need additional information. Good luck and kind regards.

Does the motorola t4500 have an eliminator

Setting a Channel

Your radio has 22 channels. Channels 1-7 and 15-22 are 1 watt. Channels 8-14 are

0.5 watt. When the radio is on a 1 watt channel, displays. When the radio is on

a 0.5 watt channel, displays.

1. With the radio on, press . The current channel flashes.

2. Press or to set the channel.

3. Press to save the channel setting. You have a pretty straight forward Low wattage FM Walki/Talki

I would have them returned or replaced.

If you can not transmitt on one to the other

Have purchased two sets radios s/hand. Will not work on any channels

Can you provide more details? What's the model of your radio? Or have you read the manual completely? There are radios that can't capture all channels. To be sure, ask the store where you bought it.

Repeater channels

Are you certain you are near a GMRS repeater in your area? If you have your radios set for the GMRS repeater channels the radios will not talk to one another unless you are in close proximity of a GMRS repeater. To talk radio-to-radio you would need to set your radio to one of the simplex frequencies available in the radio.

If you know you are close to a GMRS repeater, you might double check the Tx and Rx frequencies of the repeater to be certain they match the settings in your radio. Also, you will need to be certain your interference code is set to zero (the off position) to be used with the repeater. I didn't read up on the T7200, but if it has a Qt filter, set it to zero also.

Motorola T6550 pair.

I can see where this feature can seem somewhat inconsistent. But if you think of it like a phone ringing, it is easier to understand. Once you have answered the phone, the phone stops ringing. And the person who called you never experiences a ring on their end.

VibraCall® Alert
Page 26: VibraCall is a vibrating alert that notifies you that your radio is receiving a message. This is useful in noisy environments. When the alert is on, the radio
vibrates once every 30 seconds when you receive a message on the channel and
code you set.
• To turn vibrating alerts on, press menu until the vibrating radio symbol is displayed, then press the plus (+) button to display the letter Y for Yes.
• To turn vibrating alerts off, press menu until the vibrating radio symbol is displayed, then press the minus (-) button until the minus symbol (-) is displayed.

Cobra microtalk LI 7500 WX

fyi my Cobra microTALK LI7500-WX came out of the box with one of the radios slightly off frequency, limiting range to about 100 ft. I was able to use a counter to fix it. The freq adjust is under the front faceplate that covers and protects the LCD screen, pry it off to expose one tuning pot.

The talkabout t5500 and the t5725

Hello bella-9,

The T5500 is a 2 channel radio and the T5725 is a 14 channel radio. However, the radios should be compatible with each other on FRS channels 1-14 as long as both radios are using the same Quiet Talk code. If the Quiet Talk settings are different the radios will not be able to communicate with one another.

Assuming all settings are the same (as you say) and the units are within range of each other (typically less then a mile over clear, level terrain) they should work just fine.

Best Regards,
