what is the range in km of the Puxing PX-777 UHF 400-470Mhz Handheld Portable Two Way Radio Interphone Walkie Talkie and Earpiece
1329682
I have never used it to transmit more than half a Mike or 1500 meters. I have been able to pick jp transmissions more than two miles or 3 kilometers away with ease.
1329683
in a city environment the range is slightly less because of the large buildings and interference from other radios operating in the area
1329684
I use my Puxing radio in a location that is mountainous and heavily wooded. At times I have a range of about 5- 10miles. So, the range is dependent upon the terrain.

I haven't tested it with exact values, but it works well within 0.6 to 1.2 mile radius in the city, and up to about 6 miles radius flatland without any obstacles with 2 of these radios. It is a 5W/UHF with 4W output if that helps for calculations.

Around 16 km for simplex, but it varies widely. Altitude is very important. If one of the two people communicating is at a high, unobstructed location, then it could be 35km or more. In many cases, people make use of a repeater, which could allow a 50 km range. Also, if you attach a better antenna than the included "rubber duck", that range could double or even triple.

Without a license and a call, I would never take a distress call seriously unless you could properly identify. Second, with VHF/UHF on a handheld, the range is going to be very limited and there probably would not be anyone within range to hear you anyway.

I have not researched or got into the digital phone freqs. It in my view would have to be apco25 capable. I would email Durham radio and talk to Lee

I have used a dual band radio and transmitted between 144-146 MHz (2 meter band) and 430-440 MHz (70 centimeter band). I hit the repeaters without any problems and with full quieting. I have it on a Baofeng UV-5RE Plus and it works quit well. Hopefully this answers your questions.Fred

The range of the handset to the base is at least 1/4 mile. We use them at the barn and the base is in the house. No setup for the intercom - just push the button on the handset or base. Same goes for finding a lost handset - which REALLY comes in handy!

Unknown frequency, Likely FM, the range is about 25 feet I just use for Aviom Mixer to Wireless to In Ear Monitors but stand only a few feet from mixer.Good for short range.

that depends of course on the power of the radio station. Simply put, at this time: of all portable receivers that i have played with (and i have owned too many) this is the most sensitive for FM. For AM: It is not in the same league as the PL-310ET (the ferrite rod is too short).For SW: distance is not the issue, but time of day and sun activity -but it is quite good.In worst case, Amazon is very generous in understanding that this was returned because it did not meet your requirements

I do not have that information. I advise that you contact the manufacturer for the transmitting frequency.

It works on 2 meters and 70cm but not sure how wide freq range it has! It's pretty flexible and works well on Baofeng

Well, if you live on the edge of a cliff on a very tall mountain and your friends are 15-20 miles away across the lake (with nothing between you but air), then yes you probably could have that conversation (I have on several occasions worked over 100 miles on UHF simplex with my handheld and the standard rubber duck antenna, but I was 9,500 feet up a mountain looking down at flat farm land in AZ). Otherwise, the other folks are correct. In "normal" conditions (and this is just a rough estimate), every watt on VHF/UHF FM equals approximately 1 mile in range, so your 1/2 watt FRS radios really only work about 1/2 mile, not the outlandish claim of 35 miles the manufacturers mark on their boxes.

the frequency range is 926-928 MHZ P.S. for the money these are the best wireless headphones you can buy and as always amazon rocks with there service.

I would say about 75 feet. I bring my cordless handset to my backyard and have perfect clarity.

30-40 Cm I think. And this is not good for handsfree call. Voice quality is bad.

Its not that High sound and its vibrate as well the problem with it its very limited range I think they mena 500 M not 5000

In an open field, you can expect approximate range of 15-25 miles. If you do not understand the concept of amateur radio, chances are, you should not be buying this equipment.

It has a long range. I can get 200-250 ft from the phone before it disconnects
1614473
The range is about 30 feet from the base. No phone jack is needed for the second phone.
