After some DCS/CTCSS coding on that radio and a handheld, I did a little bit of sampling in neighborhood. Blue tooth literally cant work 20 around a corner in trees or over a small hill. If strict line of sight were obligatory, none would work within the confines of any building, much less 1/4 mile in downtown Manhattan, but clearly if a unit works at all in such extremely blocked areas, a higher power is still going to produce a stronger signal that may reach farther. GMRS Frequencies for Repeater Use

The frequency you see in the repeater listing is a repeater output, i.e. Thanks for this article.

Also what are the realistic ranges in a forest with dense trees. I have been searching. The Jp-350 Pro is small and can be easily slipped into a pocket or backpack for easy transport without losing the power of a larger radio.A GMRS radio’s entire purpose is to communicate with someone else, so go ahead and be prepared with the Midland GXT1000VP4 pack of four. The No BS just straight shooting honesty, what a concept! Yes they fit nicely in your pocket, but if you are looking for better performance, fork out some $ bucks and get REAL radios with mil specs and removable antennas. The newest radio from BaoFeng, the UV-5X3 has all the latest upgrades and is the first radio from BaoFeng to offer tri-band. Using within urban areas seems rather pointless, with massive high signal blocking structures everywhere; outdoors, they can be extremely useful. However, that isn't the scope of this article. There are many variables to consider; however, one that eludes many people are those cute little rubber duck antennas. It led him to think what if SHTF and what does it takes to survive. the frequency that repeater uses to repeat what it hears on the repeater input frequency. They are but useless after-thoughts as far as engineering is concerned. Yet, all electronic design elements being equal, wattage is the only measure of power contributing directly to signal strength, so is the only reliable means of comparison.

BTECH UV-5X3.

Here are 4 GMRS radios for your choosing. Notice that we can use the kilohertz values of each pair as “channel designators” (e.g., “channel 550,” “channel 575,” and so forth). Haven't done any repeater testing just yet, but that's next.A lot of verbiage expended to prevaricate and yet, in the end, fail to justify ignoring the wattage of units. If power and longevity are important to you, go with a larger model that has more options and a larger battery.

I think most can agree the manufacturer advertised ranges are unrealistic most of the time in most situations. With its large capacity battery, it lasts 30% longer than BaoFeng’s previous models. I would classify our terrain as in between urban/suburban.

If you want the latest technology, the BTECH UV-5X3 tri-band radio is for you. In order to use one within the United States as someone over 18 years of age, one must obtain a GMRS radio license through the FCC. The buttons on it are large, and the display is easily readable.The long lasting battery and easy to use features make this ideal for a beginning survival enthusiast.Get the Juntai Jp-350 Pro and share with a friend or family member! This pack comes with four headsets and two chargers to use with the four provided rechargeable batteries. It may read 16 Miles, 26 Miles, 36 Miles or more, and is implied to be the mileage rating of the radios enclosed. They’re divided up into channels that exist between 462-467 MHz, which are spaced alongside those assigned to the FRS.
