 A handheld dual-band is an incredibly versatile tool. Depending on the radio, they support a range of antennas, headphones/earpieces, and power options. With the right accessories, you can even mount them to your clothes or backpack with [[gear:pals|tactical webbing]]. All of these support the use of [[tools:chirp|CHIRP]] for relatively painless programming.
-  * The **UV-K5** and **UV-K6** by **Quansheng/Anysecu** are very cheap, incredibly impressive handhelds. They are impressive because you can easily swap out firmware, giving them toys like **spectrum analyzers**, reception of everything from **50-600 MHz**, and a slew of other neat functions. Some firmwares unlock them further, allowing them to transmit on additional bands. As **IEEE Spectrum** recently remarked: [[https://spectrum.ieee.org/quansheng-uv-k5-hacking|"The Most Hackable Ham Radio Yet"]].
+  * The **UV-K5** and **UV-K6** by **Quansheng/Anysecu** are very cheap 5-watt handhelds.

As **IEEE Spectrum** recently remarked: [[https://spectrum.ieee.org/quansheng-uv-k5-hacking|"The Most Hackable Ham Radio Yet"]].
-    * For those starting out with custom firmware options, we highly recommend the use of the [[github>egzumer/uv-k5-firmware-custom]] package, as it supports painless flashing via Chrome-based web browsers. It is packed with features, makes the interface on the tiny K5/K6 screens far easier to read, and it comes with the aforementioned spectrum analyzer mod that makes these great scouting radios for discovering transmissions.

-  * The **TD-H3** and **TD-H8** by **Tidradio** is another popular handheld series that can be unlocked with custom firmware. They cost marginally more than the K5/K6, but offer full-color backlit screens.
+  * If you are a novice and the idea of flashing your radio's firmware sounds daunting, the 5-watt **QYT KT-8R** is a great first handheld to play with. It has a large easy-to-read color screen, supports a wide range of frequenceies, and it can **//listen to 4 channels simultaneously//**. This makes it a great first-time radio to start on, as you can upgrade to a dual-band such as the aforementioned K5/K6 series later, and still keep the KT-8R around as a practical secondary radio. Why would you want two handheld radios? Because between the KT-8R and a normal dual-band, that means you can monitor **six frequencies at the same time**, which is obscenely useful in crowded urban areas.
-  * **Baofeng** has a massive line notoriously cheap handheld VHF/UHF radios. Baofeng was who renewed the world's interest in dual band radios, because you could get a **UV-5R** for $25, and program it on your computer to pick up a whole bunch of different things, when comparable walkie-talkies cost over $100. Nowadays, you can find better handhelds for comparable prices (see above), but these things are **everywhere**. Other popular models include the **UV-82** series, and more recently, the **UV-17R** & **UV-5RM** series. These aren't the most precise radios. They're also dirt cheap. You won't mind if you lose one down the side of a mountain, or into the sea, or if it gets stolen. Two important notes:
+  * The **TD-H3** and **TD-H8** by **Tidradio** is another popular handheld series that can be unlocked with custom firmware. The 5-watt **H3** costs marginally more than the K5/K6, but offers full-color backlit screens in a slightly more compact form factor. The larger **H8** costs a little more, but has a whopping **10 watts** of broadcasting power. The custom firmware options are not as fully developed or easy-to-install as the K5/K6 yet, but hackers are [[https://www.facebook.com/groups/456942886822492|already on it]] so we expect these to become quite versatile handhelds in the near future.

You won't mind if you lose one down the side of a mountain, or into the sea, or if it gets stolen. Three important notes:
     - Most of these radios have the same frequency ranges. Others are more limited. Check the specifications **before you order**, to see what frequencies that specific model can access, //as this can sometimes vary wildly from model to model, and even different production runs of the same model//. You can program these, but they are harder to unlock, and many of them cannot be unlocked.
+    - Most of these are 5-watts, though some models boast up to 8-watts of power. Again, you'll have to research this yourself. There are simply too many Boafeng models and sub-models to catalogue here, and all of them //(even the "high power" ones)// are entry-level radios at best.
     - Watch out for knockoff Baofeng hardware, as there is a lot of it. Only trust direct sellers of Baofeng (and **BTECH**) products. Be especially wary for **counterfeit USB cables**, as not every programming cable that carries the Baofeng logo will actually be able to program your radio.
+**One final important note:** Just because you can unlock some of these radios to use all the frequency bands, **//doesn't mean you will get good performance on these bands!//** This is especially applicable to those using custom firmware on the //K5/K6 series// trying to transmit on 50 MHz. **//The chips in these radios simply were not designed for that kind of use//**. Reception is one thing //(and child's play for the tuners)// but as far as transmission goes, stick to what the radio was designed for if you want other people to actually hear you!

 Marine Radio is all over the place, depending on the type of radio and what part of the world you are in. One popular marine radio band is in the VHF spectrum, which you can access with dedicated marine VHF radios, or with the aforementioned dual-bands and amateur radios. Keep in mind, that **Marine VHF Radio** is structured a little different from other walkie-talkie channels, **with different frequencies (usually) used between ships and the shore**. Many of the marine VHF radios will be water-resistant/water-proof and have [[gear:wx|weather radio]] reception built in as well.
-Some marine frequencies are in the HF range between CB and AM radio, and require radios that can work on those frequencies. Unless you plan on buying a boat, you will not need a dedicated marine radio. Dual-bands, HF transceivers, and many amateur radio models, can communicate with various marine radio bands already.
