Two Way Radio Pack

A lot of two way radios do not work in schools because of interference. Are there some that do work despite many walls and rooms and furniture inbetween? Also we need a quad pack for under £100!! Its not much to work with, but any advice is greatly appreciated.

Hi

I work with a Walkie Talkie (two way radio) company and I was speaking to them the other day as they have just kitted out a school which focuses on children with autism, I have emailed them so they can provide me with the information that relates to your question.

If you want to visit their website anyway, you may do so here

I will post again tomorrow with the information they give me :)

The Cobra CXR800 2-Way Radio comes in an ultra-compact GMRS/FRS two-way radio value pack with a range of up to 27 miles. The Cobra CXR800 2-Way ...

For example, I am very interested and will most likely purchase a new 2-way radio (GMRS/FRS), specifically the Cobra LI-7200/2WXVP GMRS 2-Way Radio Value Pack that boasts a 27 (that's TWENTY-SEVEN) mile range, when, in fact, from reading many, many reviews, the most that has been reported is maybe 2 miles?

Now, I understand that there are MANY factors involved, such as urban usage - buildings, houses, cars, trees, etc., but seriously, that is more than a 75% difference. Where are "they" coming up with those astronomical figures? Are the using the ocean, or airspace as their testing grounds?

You know, Walt Disney World covers about 47 square miles which is about the size of San Francisco or two Manhattan islands - so what good are these or any other two-way radios?

If you mention skiing in the mountains, don't bother cause I was using a 2-way radio while skiing in Colorado and took a wrong turn and ended up literally in the streets of town and I couldn't contact any of my party for assistance which led me to walking 2 miles in my rented ski-boots just to find a bus. Now, I am from Florida and let me tell you, we aren't used to ski boots when they are attached to skis, so don't think us boys down here like them any better now.
In my title, I meant to type "boast", not "boat".
A GMRS license? Yeah, right. Then why don't they include one (or information)when you purchase any GMRS 2-way radios that are for sale to the public? The ones I am referring to are the maximum power output allowed by law.

Click below for the 2-way radios I am referring to:

"marketing hype"? Seriously, it sounds to me like "false advertising", in which case, a lawsuit should be filed, eh?

Pure marketing hype. Manufacturers want to sell radios. They inflate their numbers drastically. You will not make more than 2 miles. I can't even make 27 miles with outdoor GMRS antennas.

License requirement information is in the manual of every radio. Yes, a license is required for the GMRS frequencies.

Price: $129.99 $74.72

iVOX hands-free communication without the need of an audio accessory
Dual power: 10 hrs. Alkaline (3AAA) or 8hrs. NiMH
A range of up to 23 miles under favorable conditions

We need 4 two way radios but they only come in 2 packs. What do I do?

You don't need to "program" them as such, just set them to the same channel and privacy code, that's all.

Such radios have no real security as cordless phones do.

Pardon me if I sound skeptical about your license, but how did you pass you license exam if you can't estimate the range of this radio?

Does AudioVox GMRS two way radios, slim line design come in more then seven miles? I need 18 mile...

This is what I already know ...

Audiovox offers the slimmest line of GMRS two way radios on the market today. Our slim line design handheld radios offer an "ultra compact" feel as well as featuring an FM radio, high intensity LED flashlight, ear mic, carrying case and comes in single or dual packs.

Thanks...

Be advise that these radios, regardless of how many miles it says it can go up to, NEVER live up to it's advertised promise. Even when used on the high power channels, which requires an FCC license before operating, is good for no more than a few city blocks in the city. In open terrain, it may get the maximum distance.
