We recently got some Motorola MOTOTRBO SL 7550 radios at work. I haven't had much chance to use them yet. Other than what is here http://www.motorolasolutions.com/US-EN/ ... d=SLSeries what are some other places to learn more about this. About all I really know now is they are:

-2 watts

-small

-Moto Trbo

-Micro USB chargeable

-Bluetooth Capable

The sales rep that sold them to you would be a great place to start

TRBO only, no analog. GARY

They are turning out to be a great radio. I had my reservations at first, but they are standing up well. Good audio. Nice size. Nice little radio.

If used for work on a Trbo system that's close by like a hotel, it's great. My friend uses his for ham radio, & he has no problem. When I told him it was not analog, he didn't care & said he has another radio if he want's to use analog. I think he likes it because it looks like a phone. But his works fine. GARY

The SL is a great radio in a Hotel, and excels at data operations.

Only major item for consideration is that the SL7550 is 1/2 range of the other XPR radios (power down 3dB and antenna performance down 3dB). I find that they typically run on in-building repeaters, so it hasn't been a significant issue.

Does anybody have any speculation on what sort of range one might get on 2 watts, UHF 410.xxxx on simplex? Would 1 solid mile, say caravanning in vehicles on a relatively flat interstate be reasonable?

I'm lucky to get 1 mile with a couple of 4 watt Jedi's using 6" antennas. It would be even less with the 2 watt radios & cell phone type antennas that come on that radio. GARY

My new home QTH is on the 11th floor of the building, so I have no trouble
accessing our main local TRBO repeater, which is about miles from my place.
The single-mode 7550 is a great radio but it's strictly for close-in, low power
work.

But hey, who in his right mind ever imagined that Motorola would be selling a
portable whose replacement batteries cost only about five dollars each?

Neat little radio. Bought a couple of extra batteries off Ebay real cheap. Battery life isn't the greatest but when batteries are cheap, who cares?

Grab the fancy charger which will allow you to charge the radio, an extra battery and your Bluetooth headset at the same time.
