SOURCE: 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.

SOURCE: 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.

SOURCE: can transmit to other frs radios but cannot

Check the "code" (interference eliminator code) on the FR60 and set it to off or zero. It appears from your description the Cobras do not have "code" turned on. Refer to your user guide to find the instructions for turning off the code. (As of this date we have not found an FR60 manual posted online.)

Best regards.

SOURCE: My motorola RDU2020 radio receives

1) You possibly have a bad or nearly dead battery. Transmit takes more energy than receiving. With this in mind, your radio's transmit will fail, if you have a poorly charged or bad battery, when pressing the PTT. Try a battery from a known good radio to see if it eliminates the problem. If so, replace your battery.

2) The radio is either programmed incorrectly or in need of repair. If you have been experimenting with the programmable features, we suggest you walk back through the steps of programming. Here is a link to the user guide: http://www.mytoolstore.com/motorola/rdx_userguide.pdf Programming instructions begin on page 36.

3) If in need of repair. Radios less than one year old should be under warranty, barring any physical or water damage to the unit. Contact the place of purchase or Motorola for warranty instructions.
If the radio is more than one year old you can get it repaired at any dealer offering Motorola repair. (approx. $85 flat rate)

Best regards.

Motorola KEM-P29923 2 Way Radio. It can transmit but cannot receive messages.

There are some ideas here, but also make sure Squelch isn't all the way up, that you aren't on some type of mute and that the Volume isn't at Zero.

Motorola talkabout MJ270R switching off when transmitting

Turning off while transmitting is typically a sign of a weak or bad battery. However, since you mention it happens with either battery type, another cause might be the length of time you are depressing the PTT button. These radios have a fail-safe to prevent damaging the final amplifier of the radio. To protect itself the radio will shut down or stop transmitting after the PTT button is held in too long. This being said, I'd check the batteries first. The rechargeable battery pack which came with the radio has a one year life expectancy. A battery can test full when it is weak and might not hold the charge when placed under a load. And usually transmit is the first thing to fail.

Best regards.

T5420 unable to transmit or receive. Please help!

Here is a link to the T5000-T5500 user manual. 'http://www.motorola.com/mdirect/manuals/T50-T55_UserGuide.pdf'

From what you have stated, I can discern the radios will power up. You might try setting your interference eliminators to zero (off) to see if you are able to transmit at all.

You do not mention if you are using AA batteries or rechargeables. Either way a fresh set of charged batteries would be best for a test. It is clear you were getting power. However, it does take more energy to transmit than to receive. If your batteries are low or bad, pressing the PTT could us all the energy the radio has, and yet not transmit to the other units.

You might also check you VOX settings if any and be certain they are turned off.

It is not likely 4 radios would fail all at the same time. So it is probably a programming problem. Hope the user manual helps you find the solution.

FR60 intermittent transmission

Hello snorker,

It could be battery / power issue. Two-way radios draw much more power when transmitting then receiving. If the batteries are weak the radio might work perfectly fine on receive and then cut-out when you depress the Push-To-Talk.

Problem transmitting

Hello jayhawkrx,

Check the Continuous Tone Coded Squelch (CTCSS) settings on all the radios. (Note that some manufacturers refer to this feature as a Privacy Code or Quiet Code. The actual name of the feature may vary.) This feature encodes a low-frequency signal on your radio transmission. This signal is below the range of human hearing but can be detected by other radios. When the CTCSS feature is active your radio will ignore any signal that it receives that does not have the proper tone encoded on it.

In order for these radios to communicate, all of the radios need to be on the same channel and have the same CTCSS code programmed or the CTCSS feature must be disabled.

I suspect that CTCSS is activated on one of your radios but not on the other. This would result in the situation you describe.

Also take note that when using different brands / models of radios to communicate with one another that the CTCSS code numbering scheme may not necessarily be the same from radio to radio. For instance, CTCSS code 4 on the Motorola TalkAbout series actually corresponds to code A on the Motorola Sport models.

Best Regards,

Agent Ken

Midland gxt-850 gets HOT!

Hi,

It is very possible that the terminal of the positive end of the bottom battery is shorting to the battery's body hence the heating up. If this is the case, then when you charge the radio, excessive current is flowing since the battery set has one shorted. Again this would cause heat buildup specially on the bottom battery and the charging terminals.

A possible solution is to check the bottom battery's positive terminal and ensure that it only contacts with the positive terminal of the battery and does not touch the battery body (which is negative).

Alternately (and perhaps more to your advantage), seek replacement of the defective unit considering it is new and therefore should be under warranty.

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

Good luck and kind regards.
