Question about Motorola Talkabout T5800 (22 Channels) 2-Way Radio

1 Answer

Transmission problem One of my T5800 units will not transmit anything but the the "music note" when I push that button (the button above the "-" on the face of the unit). Otherwise, when I push the PTT, the microphone doesn't engage, nor the the indicator light go from blinking to constant red. It doesn't appear the PTT switch can be replaced easily. Suggestions?

Re: transmission problem


A couple of things you can try:
1. Use electronic contact cleaner (spray type) on the PTT switch;
2. Use an external speaker/microphone and/or handsfree VOX headset
3. Replace the PTT switch. 4 solder points. Might not be easy but doable.

The last would require that you remove the defective PTT switch and use that as per sample when looking for replacement. Some printers uses the same type of switch. Familiarity with electronic components/circuitry, use of a DVM and a soldering iron would also be required.

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

Good luck and kind regards.

Can't transmit signal. Only get a 2 second beep when I push the transmit button

You have a poorly charged or bad battery. It takes more power to transmit than to receive. Usually the first thing you lose with a low, bad or poorly charged battery is transmit.

Try a known good battery in the radio. This should solve the problem. If not, check your battery contacts, as you may have one which is bad or not making good contact.

Clean your contacts with a pencil eraser to assure good connection with the charger.

Best regards.

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.

Best regards.

Talkabout T5800 (22 Channels) 2-Way Radio: droped in water will not transmit but will receved...

Depending on the type of microphone used, if not the type using the speaker as a microphone, it may be damaged. I would though, suggest you remove the battery, open the case and allow the innards to dry in a warm place for several days. Even daily exposure to the sun should work fine.

Can Receive but not Transmit

1) Double check your interference code eliminator and the Qt filter. Make certain they are all set identical.

2) If you are still having trouble, shut off the Qt filter.

3) Then if you still have trouble shut off the code. (Off is sometimes "zero" or "n" for no.)

4) If the above steps do not help you have either a defective radio, or a bad battery. Switch the batteries out of the working units to the non-working and see if the problem switches to the other units. If so, replace the battery packs. (Note: it takes more battery power to transmit, so the problem would first show up in the transmit area.)

Best regards.

Won't transmit

First I would check the interference code on both radios to see if it is set the same. It is possible you have one set to zero and the other set to another number. This would cause the problem you describe. The interference eliminator is designed to block out transmissions from radios whose settings do not match it.

If all your settings are identical, and you have only 2 radios, it is not possible to tell which one has the problem. You either have one with no transmit or one with no receive. The only way to tell which you have is to get a 3rd radio involved, set to the same settings.

Motorola T5622 VOX Not Activating with Autocom Sys I have an Autocom (Kit 300) motorbike coms system. I bought the accessory cord that interfaces to the Motorola T5622, for VOX I have followed the Motorola...

Hi Folks, two seperate checks to do - to check vox on autocom and transmit on motorola. With the T5622 unconnected to anything, does the push transmit button work - e.g. does it make the beep noise at the end of transmission?

Does your autocom work with any other sound sources - i.e. mp3 player so you can hear music. Does this mute when you speak ? (it should if vox is working). Note that in this setup vox is provided by autocom - NOT BY THE T5622. The instructions you mention are for the motorola vox kit.

Wire the two together and you should get the motorola beeping through your autocom at the end of transmit - that's what my kit 200 does with my T5622.

By keeping the PTT button pushed, if you get a rapid beep and the red led is blinking, sounds like a bad battery. Batt voltage is a nominal 7.5v. anything lower than 6.25v and the low battery beep starts. A rapid beep, and no red led blinking, an error in the transmit freq.

Staying keyed up after button release

I have never seen this problem before, check if the VOX is activated, this could cause to transmit the radio, but the voice must be transmited. check if the Accesory connector is not dirty, clogged or damaged
