How many watts do midland walkie talkie xt20 have?


These are FRS/GMRS (Family Radio Service/ General Mobile Radio Service) radios. The legal power limit for FRS is 500 milliwatts - or 1/2 watt. GMRS on the other hand is limited to a much higher 50 watt level. The wattage you transmit determines if you need to have a GMRS license. Most GMRS radios are in the .5- 5 watt range however.

The likelihood of your XT20 being a 1/2 watt out on both FRS & GMRS is very good. For Midland (or anyone else for that matter) to produce a radio with a 1 watt output that can run on just 3 "AAA" batteries would be quite the feat! If Midland did do this, the radio's battery life would extremely short. To balance the needs of light weight and battery life, output power needs to be reduced.

Claims of 20 miles is crazy. If you had these radios on mountain tops 20 miles apart - with a clear line of sight between them - MAYBE - you could hear one on the other. This would need to be done under only the most ideal conditions. The actual distance you can expect to get out of a pair of any brand FRS radios in "real world" conditions (line of sight blocked by trees and buildings) is about a mile.

An FRS/GMRS radio limited to 1/2 watt output when used on a GMRS frequency that is close enough to access a GMRS repeater system could easily cover 20+ miles. The key here is having a license and access to the repeater. Repeater owners take a dim view of unlicensed users access their repeater.

Channels 1 thru 7 are FRS and GMRS. That is, if transmitting .5 watts, you can use it as FRS. If transmitting more than .5 watts, you will need a valid GMRS license.

Channels 8 - 14 are expressly for FRS. Only .5 watts transmit power is permitted.

Channels 15 - 22 are expressly for GMRS at any transmit power up to 50 watts. Even if transmitting .5 watts, you MUST have a valid GMRS license on these frequencies.

I know - more infor than you wanted and no vclear cut number for wattage - but there's no info on these radios on Midland's site or anywhere else that I could find. Good luck!

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!

How to get a Talkabout T5720 to communicate with a


The frequency range and operatngmode of the two radios are compatible. To get the Radius operating on a GMRS channel you'll need a Motorola programming cable and software, OR a trip to a Motorola dealer for frequency programming. Considering the cost involved, the 2-watt output of the Radius, and the 1-watt output of the Talkabout, you would be better off performance and cost wise buying a pair of 5-watt GMRS portables.

Radios will not trasmit


The Motorola T-6510 uses FRS-GMRS frequencies the TK-3130 uses 2 UHF frequencies. Unless you had the radio custom programmed to match the GMRS frequencies it will not work.

Reprogramming a Maxon SP 100G?


Hello codeencrypt,

THE SP100G is essentially the same radio as the SP100U UHF business band unit that Maxon made at the same time, just pre-programmed for GMRS. I believe there is a programming kit for this radio (Model number: SPK400C) which may still be available for purchase from Maxon directly. Otherwise, your best bet is going to be contacting your local Maxon dealer to see if they have the capability to program he radio.

Best regards,
Ken
