Motorola DTR410 Digital On-Site Two-Way Radio Review

Average Reviews:

(More customer reviews)I tested a pair of these radios against a pair of 4 watt UHF portables and the range of these radios was a lot further. I belive it is due to the fact that these radios operate on 900mhz and are digital.

TriSquare TSX100-2VP eXRS Digital Two-Way Radio (Pair), Charcoal Metallic/Black Review

Average Reviews:

(More customer reviews)The TSX-100 radio is simply one of the best short range 2-way radios available.It uses the 900Mhz ISM band (902-928Mhz range).And is full 1-watt.Uses spread spectrum technology (similar to CDMA Cell Phones:Sprint, Verizon Wireless, US Cellular, Cricket) which makes it JAM-PROOF and highly unlikely that anyone can monitor while using the best scanner radios.900Mhz band means easy penetration thru thick walls and buildings with dense materials concreate and metal.It is simply the best for Indoor-to-Outdoor or vice-versa comms.And has identical coverage with VHF when used for Outdoor-to-outdoor use.

The TSX-100 does not have all of the exra bells and whistles of the TSX-300 radio:

- 1,000 virtual channels (using FHSS)
- is compatible with all TSX-100 radios
- is compatible with all TSX-300 radios (below channel 1,000 ;
channels 0-999 allows interopability to any Trisquare radio)

(See my review of the TSX-300 for a list of some of the bonus
features on the TSX-300)

With the PRO features, there is one notable CON:

- Do NOT place the TSX-300s or TSX-100s too close to each other.
- They sometimes experience De-Sync issue when a unit nearby
transmits too close.So keep them 4 or more feet apart from
each other.This only occurs when too close to other Trisquare
radios.This does not seem to occur when other nearby radios
or cell phones are placed too close.So no need to worry about
MURS, FRS, GMRS or HAM radios are under 3 feet away.

At least 95-100% of all of the bad reviews or complaints about this radio is over this single flaw in the radio.Rule of thumb, keep the
TSX-300s and TSX-100s a minimum of 4 feet apart from each other at all times, and you will never have any problems at all.Simple right?

Even the TSX-100 is so much better than any MURS, FRS or GMRS radio.
900Mhz just has superior radio properties over all VHF and the rest
of the UHF band.900Mhz penetrates and bounces around inside buildings
better then any other UHF service.And certainly superior over VHF as VHF does NOT bounce well inside any buildings.Instead VHF gets knocked out of phase, and its wavelength mostly gets cancelled-out or worse yet ABSORBED into the building's materials:concrete, wood & metal. VHF is an OUTSIDE only band.UHF is a good inside and outside band.900Mhz has the best properties.FRS/GMRS operates at 462 & 467Mhz.Take 462 x 2 and that equals:924Mhz, which means that 900Mhz has a wavelength that is HALF that of FRS/GMRS.Which means none of the wavelength phase interference of VHF or even of the low-UHF at 462Mhz.Again, it boils down to superior in-building penetration.Thru Concrete, Wood & bouncing off of Metal.

Enjoy your TSX-100, enjoy the superior 900Mhz properties for indoor-to-indoor or indoor-to-outdoor (also vice-versa), or even outdoor-to-outdoor comms.Its FHSS full 1-watt of power will show its superior ability over all MURS, FRS & GMRS radios.

- MURS - VHF 2-watts ERP (Poor Indoor properties - not recommended for
any indoors use at all ; Any scanner can receive, no privacy)
- FRS- UHF 1/2-watt(Good Indoor properties - 1/2 watt max power)
Any scanner can recieve, no privacy ; some HTs have limited voice
scramble function)
- GMRS - UHF 50-watt (Good Indoor properties - 5-watt HTs are hard
to find ; Any scanner can recieve, no privacy ; some HTs have a limited voice scramble function)
- EXRS - 900Mhz 1-watt (Superior Indoor properties - full 1-watt HTs)
FHSS assures no scanner can monitor, wonderful privacy feature)

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. 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.

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 radiosThose 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.
