Customer Review: Superior to FRS
Summary: 5 Stars
Got mine from Amazon about a year ago. Paid less than $80 (with shipping) for the two radio set with charger. The "Black and Grey" units were my choice, but the Camo units are pretty snazzy.
I've been into radio my entire life as a hobby. I have bought and used so many FRS radios, CB walkie talkies and various amateur radios I cannot name them all. I'm not downing or bad mouthing FRS at all, but since I bought these radios, I will not go back. FRS is good for socializing, but for privacy and immunity to interference, the Trisquares are far superior. I range tested them against three different FRS radios, and the Trisquare was superior. Trisquare does not play the "Range Game." Trisquare simply states that their radios will outperform FRS in terms of range, all things being equal.
At one Watt output, the Trisquare is twice as powerful as a full output (.5 Watt) FRS. This "should" give about 25% greater range, all else being equal. My testing confirmed this with the three FRS units I range tested against the Trisquare.
The radio feels quite substantial and fits in my average sized hand perfectly. The contoured ribbed sides give a secure grip. One fell out of my coat pocket onto concrete from a height of about five feet. The radio only took a small ding, but still functions perfectly. The back-lighted buttons are arranged so as to be easily used with the thumb, so one handed operation is possible. The keyboard can be locked and unlocked with a single button push, and the power button can be used to turn the display lamp on or off. There are no rattling or loose parts inside.
I found the belt clip to be flimsy, so I tossed it and glued on a cell phone swivel button instead. The combination microphone/ear-piece was also flimsy, so I tossed it, but the TX/RX sound quality was good. Any "unpowered" single-pin Motorola mic/earphone will work with Trisquare.
The radios' battery can be charged while in the radio or separately in the drop-in charging base, but the radio doesn't sit securely enough in the charger to ensure reliable contact between the charger and the radio's charging contacts. The 750mAH NiMH battery is functional, but a higher capacity battery would increase operating time. A LiIon battery pack would be even better.
There is a bit of a learning curve to this radio, which is easily overcome by reading the online manual while waiting for the units to arrive. Menu options are quite intuitive.
Wireless cloning means no extra money spent on a cloning cable to set up a fleet of radios. Just set one up as you like and then clone the rest. Neat!
I carry the pair with me everywhere. I use them with my wife, kids and friends. When a cable tech came to my house to do some troubleshooting recently, I lent him one so we could coordinate his efforts.
Weather reception was about as good as one could expect from a radio that has such a short (one inch helically wound) antenna. I was able to get reception in Redlands, Ca., but it was marginal at best. An extendible antenna such as found on some cell phones would improve the Weather receive and increase communication range. Even so, I was able to get reliable communications out to approximately one mile in Yucaipa, Ca., in an area filled with varying topography, trees and one story brick and wood homes between myself outside on foot and my wife inside our home.
I was able to communicate from one end of town (about four miles) to the other while I was at a high elevation. Communication was spot-on crystal clear, and I believe that the range would have been greater, but I did not test farther out because my testing partner ran out of steam and wanted to stop. Amusement parks should not present a problem, as I've read in other reviews, but your mileage may vary.
These radios can be used with any AA battery. The supplied rechargeable packs provide about 10 hours of use. 5% transmit, 5% receive and 90% standby.
The unit does have a "cellphone"-like appearance, but still a bit "toyish" looking. I'd like to see them built more "Business" like their Motorola counterpart, but for the price, it's acceptable. The Trisquare is not inter-operable with the Motorola DTR series because the two companies use different proprietary designs. Considering that the Motorola DTR series starts at $250+ EACH, I'll spend my money on the Trisquare.
The receive volume is loud enough to be heard over traffic, and voice quality is slightly digitized, but still perfectly intelligible, with a little bit of wavering sound. VOX is a nice addition, but I don't find it to be a major selling point. I verified that VOX is functional with three levels of sensitivity. I never use it.
Texting works well enough, but with only alphanumeric keys, it's a slow and tedious experience. Six pre-programed messages and five user-programmable messages add functionality and convenience, however. There is no acknowledgement that the text was received, so this adds little real value to the unit. I don't use it.
FHSS ensures that casual scanner listeners cannot monitor or eavesdrop. Even other Trisquare users cannot monitor your communications unless they have the same codes programmed into them.
10 Billion "virtual" channels (frequency hopping sequences) enables 100,000+ Trisquares to operate in range with no interference. Conversely, as few as 50 FRS radios in-range would render that service practically useless due to channel congestion.
The Trisquare(900 MHz ISM band) can hold up to 100 "contacts" which can be a combination of groups and individual units. This makes fleet management easy. You can call entire groups at once, or any individual unit directly for private conversations. Try that with FRS(452/457 MHz), and you will become frustrated very quickly.
The TriSquare is license-free, and can be used for personal or business purposes.
I should add that I have only used two of these units at the same time. The radios stayed synced up continually. It is possible that using more than two could result in one or more units to lose sync briefly, mostly when a unit would be out of range momentarily and would re-sync automatically once back in range within 20-30 seconds. This is not a design flaw. It is an operating characteristic of the FHSS emission type as executed by Trisquare.
There are reviewers who have stated that battery life is affected by the radio continually transmitting to keep sync. This is incorrect. The units transmit "only" when the PTT is pressed. I confirmed this on my own with a spectrum analyzer as part of my initial testing.
Other reviewers have stated that there is a "continuous pilot carrier" to sync all units while the unit is transmitting. This is also incorrect. I confirmed this as above. A pilot carrier would defeat the purpose of FHSS.
All in all, I feel that the money was well spent on these fine radios. For their capabilities and features, I would recommend these radios without reservation.
Sorry it was so long.

Description of TriSquare eXRS TSX300-2VP 900MHz FHSS Digital Two-Way Radio (Charcoal Metallic/Black) (Pair)
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.Digital Cameras & Photo Categories
