Question about Motorola Talkabout T5500 (7 Channels) 2-Way Radio

2 Answers

Can nice motorola GP340 talk to an FRS/GMRS w/ interference code?

So I found the frequency codes for the T5500 and T6530 that we own, and we want to program our GP340s to talk to them.

What if they are using one of the interference codes? Does the Motorola GP340, on that channel, roughly translate to '0' for the privacy code?

    We know that ours are UHF, so we know that will work. Not certain how I would include a privacy code?

If your GP340 is a UHF model, YES, you can have it programmed to match your TalkAbout radios. And yes, the GP340 has programmable privacy code capability.

If you do not know if your GP340 is VHF or UHF, you can tell by looking the model number, it will contain the following pattern: __H25RCC4AN3__. UHF models will have the letter R after the "25". VHF models will have the letter K.

When you have your GP340 programmed, the power setting will need to be turned down to the appropriate level to match the TalkAbout radios. Both for legal reasons, and also to protect your TalkAbout radios. You will not want the powerful GP340 to overpower the PA (power amp) in your TalkAbout radios.

Motorola invented this code thing about 30 years ago. They call it "Private Line", other call it CTCSS. Sure that all Motorla radios suport these codes, even the much more expensive GP340. Anyway, you need a dealer to programm frequency and code into the GP340. they are then fixed and cannot be user changed

How come the garmin 120 radio isn't compatible with standard Motorola walkie talkies


When programmed to the same frequency and code settings the Garin Rino 120 should match the Motorola TalkAbout line of radios. They are all using the same UHF FRS/GMRS frequencies. Here is a link to the Garmin user guide where you will find the frequency charts on pgs. 100-102: http://www.uky.edu/~jmlhot2/courses/for480/Rino120_OwnersManual.pdf

T5603 and t5500 compatibility


No. The T5603 is a version of the TalkAbout made for use outside the USA, and has preprogrammed frequencies (possibly PMR frequencies for the UK) which differ from the FRS/GMRS frequencies in the T5500 made for use in the USA.

Can two different style motorola 2 way radios be changed to same frequency


Hi Kate,

The short answer to your question is: no, or "not readily". Here's why:

The Motorola 4900 radio operates in the FRS (family radio service) and GMRS (general mobile radio service) in the UHF band. This radio will work with any other FRS / GMRS band radios (no reprogramming of transmit and or receive frequencies is possible for these radios). The trick is that the numbering of the channels may differ from brand to brand ie: Ch1 on your Motorola may not necessarily be Ch1 on a Midland radio or other brand. A complete list of the frequencies and channel assignments for FRS /GMRS can be found on Pg. 17 of the manual. It is important to note that without a valid GMRS license, you are prohibited from transmitting on the GMRS only channels (Ch 15 through Ch 22). The combination GMRS/FRS channels (Ch1 through Ch7) and the FRS only channels (Ch8 through Ch14) are for individuals and family members that do not have valid GMRS licenses. If this is you, you should limit your transmissions to Ch1 through Ch14 only, as FRS does not require a license in the US. Unlicensed use of GMRS only Ch15 through Ch22 can result in fines and imprisonment if caught by the FCC.

Further complicating the issue are the so called "privacy tones". This is simply a very low or "sub-audible" frequency that is sent whenever transmitting. Motorola calls these "Interference Eliminator Codes". When another radio receiver is set to listen for a particular privacy tone, it stays silent until a transmission with the exact same privacy tone is detected. Again, these tones are listed in no particular order, but are generally listed as 1, 2, 3, etc. or a, b, c, etc. instead of the actual frequency in hertz. You can selectively set your radio to transmit & receive one of the 38 codes or, set the code to "0" to communicate with radio that do not offer these privacy codes - or does not use the same frequencies for these codes. You can read more on Motorola's codes on Pg. 19 of the manual.

The Motorola CP200 radio on the other hand is a commercial radio, and requires computer programming with Motorola software. The CP200 is offered as both Low & High sub-banded VHF and Low, Mid & High sub-banded UHF radios. You would need to have a CP200 that is designed to accept the Mid UHF band (438Mhz - 470Mhz) frequencies in order to program the 462Mhz & 467Mhz FRS / GMRS frequencies into it. The final obstacle would be what is called "FCC Type Acceptance". The CP200 is probably NOT Type Accepted for transmitting FRS/GMRS frequencies, and as such the Motorola dealer doing the programing might balk at putting them in. You can read a spec sheet on the CP200 here.

I hope this helps & good luck!

Can motorola talkabout T5720 FRS/GMRS talk with Motorola GP338 UHF?


Your GP338 would need to be reprogrammed to one or more of the frequencies available in the T5720. If you are using the interference code eliminator, it would also need to be programmed into the GP338. Take your GP338 to your local Motorola dealer for reprogramming.

Here is a link to the user guide for the T5720, where you will find a list of frequencies: http://www.giantintl.com/RadioPDFs/Outdated%20Manuals/T56XX_57XX_User_Manual_E.pdf See page 19.

Will the MU21CV radio's work with the talk about radios?


Short answer, maybe. It depends on whether you have a 14 channel or a 30 channel Talk-About. The Motorola Talk-Abouts operate on the FRS frequencies (14 channel) or FRS & GMRS frequencies (30 channel). The MU21CV does cover a few of the GMRS frequencies. (see bold numbers)

GMRS Frequencies
462.500, 462.575, 462.600, 462.625, 462.650, 462.675, 462.700, 462.725, 467.550, 467.575, 467.600, 467.625, 467.650, 467.675, 467.700 & 467.725

FRS Frequencies
462.5625, 462.5875, 462.6125, 462.6375, 462.6625, 462.6875, 462.7125, 467.5625, 467.5875, 467.6125, 467.6375, 467.6625, 467.6875, 467.7125

What is the best frequency for the GMRS radio for long distance communication?


There is no "long distance" communication on GMRS. Terrain, buildings, power lines, etc. will routinely limit your communications to 1/2 mile or so, no matter what claims the manufacturer makes. All of the GMRS frequencies will yield nearly identical performance and range, but avoid the low-power FRS frequencies.

Motorola talk about t9500


Check the programming of your frequency, interference code eliminator (code) and Qt filter. Be certain all are identical.

If this does not solve the problem, take the radio back to a basic mode by turning off the special features. (Set the code to zero, the Qt filter to off, the roger beep off, the call tones off) Your radio should work easily without the extras. If the radio doesn't at this point, you have a bad radio.

Interference on frs radio from motorcycle


Hi Vince,

Have you tried to set the PL or DPL on the radio. This will not stop the interference but it will prevent your radio from un squelching while riding.
If you could post the make and model of the radio i will look for a owners manual for you.

Remember to set both radios the same or make the PL or DPL the same or the radios will not "talk" to each other. PL and DPL stand for Private Line and Digital Private Line both terms coined by Motorola. It is a sub-auditable tone that the radio will listen for and open the squelch when the corrosponding radio is transmitting the tone and vice-versa.
Hope this helped.

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.

Modify a motorola T5500 to work in different frequency


Sorry. The MHz of your radio cannot be changed. And there are no "private" frequencies available for use. However, your radio is equipped with this in mind.

There are 22 frequencies built into the T5500, along with 38 Interference Eliminator Codes. The two combined offer you over 836 choices to avoid other people. And if this is not sufficient, they also have the capability Qt filtering.
