TriSquare eXRS TSX300-2VP 900MHz FHSS Digital Two-Way Radio (Charcoal Metallic/Black) (Pair) Review
Average Reviews:
(More customer reviews)I own both the TriSquare and Motorola Talkabout radios Those of you who like to take your kids outdoors or skiing, may find this of interest.
Motorola T9500XLR 25-Mile 2-Way Radio
======================================
This is a typical walkie talkie. It 22 channels in the 462 MHz range and has 2 watts of power using GMRS/FRS protocols. The "25-mile" range is the theoretical max (i.e. on the lunar surface).The main problem with this technology is, well, other people. Imagine 1,000 people sharing 22 channels at Disney World. Motorola goes through great lengths to filter out other people. This is achieved by
(1) A special filter that blocks non-Motorola radios. A nice idea, but unfortunately 90% of walkie talkies are made by Motorola.
(2) A special privacy code which is assigned to each channel. Thus, all your Motorola radios have to be configured to the same privacy code in order to work with each other. Codes range from 1 to 121.
Nonetheless, even with filters and privacy encryption, if someone else is transmitting on your channel, there will be significant interference.
TriSquare TSX-300 eXRS 900MHz FHSS 2-Way Radio
================================================
These use a completely different technology. They transmit on 900 MHz in a 100% digital protocol. They sort of work like cell phones, without the service provider. Each radio is assigned a unique 10-digit number. No matter how crowded the ski resort, you'll always have a private channel for your family. These radios use 1 watt of power. The manufacturer does not provide distance performace, but claim that the radios have a range equal to or better than the Motorola Talkabouts.Comparison
==========
I took both brands with me and drove around town - a typical suburban setting with residential and commercial areas. I rated voice quality on a scale of 0 to 3 as follows:
0 no reception
1 unintelligible
2 intelligible but noisy or garbled
3 intelligible and clear
I then plotted the average rating as a function of distance. The digital eXRS technology was superior to the GMRS/FRS model. The eXRS average rating was 25% better than the Motorola Talkabout. The max distance I could get in my area (having lots of trees and buildings) was .45 miles with either radio. The Motorola box claims "2 miles in an urban setting", which is just not true in my case.The Motorol wins in overall voice quality. When the signal is strong, the voice quality of the Motorola was quite clear, whereas the eXRS unit always had a some background white noise.
Conclusion
===========The TriSquare eXRS radios lack a bit in overall voice quality. However, having great voice quality in a Motorola radio is worthless if you can't get through on a crowded channel. The benefits of the eXRS radios out way the one or two shortcomings, in my opinion. I tried the TriSquare units at a ski resort. They work just as advertised. No interference from other people whatsoever.
The TriSquare comes with two vox headsets, which work fairly well. The Motorola talkabout did not come with headsets, which cost $20 a piece at Radio Shack.
Niether the Motorola Talkabout nor the TriSquare eXRS seem particularly rugged or weather resistant, so I'd rate them the same in that regard.
The NOAA weather reception on the TriSquare was pretty bad. I have two other NOAA radios, which work just fine in my area. The Talkabout had very good NOAA reception.

TriSquare has revolutionized 2-way radio communication with eXtreme Radio ServiceTM (eXRSTM). eXtreme Radio Service (eXRS) two-way radios use proprietary Frequency Hopping Spread Spectrum (FHSS) in the ISM band (900 MHz frequencies). This FHSS system combines the power of digital technology with narrow band FM modulation technique. Merging the two technologies facilitates a radio communications system that maintains a narrow band base signal to ensure for maximum usable range within a given dB power budget, comparable to traditional fixed frequency narrow band FM radios, but with the added benefit of wide band digital security and privacy provided by the frequency hopping spread spectrum algorithm. Maintaining the information signal as narrow band FM modulation centered on discrete frequencies allows for a large pool of non-overlapping hopping frequencies to draw upon within a given section of the radio frequency (RF) spectrum. The pseudo-random drawing of the hopping frequencies spreads the total signal power equally over the entire bandwidth of the RF spectrum used, which ensures minimal interference between many simultaneous, independent users. Interference Free is a major advantage that eXRS has over existing FRS and GMRS radios. Based on a contracted study from the Electrical and Computer Engineering Department of a major university, more than 100,000 eXRS users within talk range can enjoy uninterrupted communications. Whereas, FRS/GMRS quickly becomes unusable with just a few tens of users within range of each other. Bottom-line is that the eXRS two-way radios provide private communications in areas where FRS/GMRS conversations can be congested or impossible. Depending on which model you choose, your eXRS radio will have 1,000, 10,000, or all 10 Billion eXRS channels available for your use. Each radio offers Voice-operated transmission (VOX) for hands-free operation with headset compatibility.
