Product Description

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.

Customer Reviews

Broadcast/receive range in the woods is less than a half mile.
The Riverfest celepbration at the Riverfront Park was a very good test for these radios.
D. Turner
For their capabilities and features, I would recommend these radios without reservation.

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.

I discovered this radio from an electrician's website. I was impressed that the company was very straightforward about the radio's specs, no outrageous mileage claims and so forth. The company even has hams on their payroll. So I ordered a pair. I found it was easy to set up. Then the test. I have one of those high powered frs/gmrs radios to test against. Set up the eXRS and an FRS radio side by side by a recorder and then took a long walk with the other pair. I would key the FRS and give a test broadcast and then with the eXRS at varying distances. Then came back through my apartment complex and angled my location to increase the number of buildings and apartment they had to transmit through, up to a maximum of 3 buildings and 46 apartments. The FRS, since it is analog, became staticy and noisy. The eXRS' remained clear. When the FRS was about to fade into the static, the eXRS finally had a little chop in it's transmission. You have to give it a second to key up to transmit, but it's a great radio and the price makes it an even hotter deal! The channels and groups makes this act almost like a trunked radio system, but without the trunk. I took it to work and then over to the radio shop (national name company well recognized for radios) and had them try to scan it and crack the channel hopping spread spectrum. Even with their equipment, they were not able to monitor a transmission. If they had the software source code, they could have, but without the source code, even with highly specialized radio maintenance equipment that cost tens of thousands of dollars, they could not monitor this radio! If you do not know the channel, you would have a better chance of being struck by lightning on a sunny day of finding a conversation.Read more ›

I've tested six of these radios for several hours. The range is quite good for a personal radio, and was better than FRS radios that I've used in the past. However, I found that whenever I changed channels on two of the units (for example, to chat privately), and then changed them back, they would be unable to communicate with the remaining units for some period of time. I also found that if you turned on two units and talked between them, and then turned on a third unit within 20 seconds or so, the third unit would be unable to communicate with the first two.

I exchanged emails with technical support and determined that the problem is caused by a design issue with these units which essentially requires you to wait 30 seconds before transmitting whenever you change channels or when you first turn the unit on. If you don't wait, your unit might become out of sync with the other units, and you won't be able to hear or talk to anyone, even if they are on your channel. You also have to keep the newly turned on unit at least 20-25 feet away from any other units that are already on, or they could become incorrectly synced.

Here's the problem: Each "channel" on this radio actually uses 50 separate frequencies and the radio hops between them whenever it is transmitting or receiving. When you first turn on a radio, or when you change to a new channel, your radio goes to the Frequency #1 for that channel and waits there until one of two things happen: Either you push the transmit button, or the radio picks up someone else doing so. The moment that happens, the radios begins hopping through the 50 frequences in a sequence that is defined by the channel number you selected.
