Ultimate Radio Communication Guide What to Look for in a Handheld Transceiver. My previous article on radio communication was a primer that went into detail about why youd want to learn about radios, the way they operate and what frequencies are available for you to operate on. There are two components the DSP and MCU chips in the UV5R that determine the band limits. The RDA1846 DSP chip is the chip that generates all the transmit and.

Im going to be referencing quite a bit of information from my last article when it comes to frequencies, so if youre not up to speed yet on the difference between say, VHF and UHF, check out my first article. What to Look for in a Handheld Radio. First off, my recommendations for radios are going to be primarily based on handheld applications. Auto Answer Software For Nokia N95 Software. While there are certainly pros to having a larger base station transceiver, the handhelds have it when it comes to portability, ease of use, versatility and more. They can be used at home, in a vehicle, or even in the field. Whats a Transceiver A transceiver, which Ill be referring to frequently in this article, is essentially your radio. A transceiver is a unit which contains both a receiver and a transmitter. While these used to be separate units until the 1. Occasionally youll see just a receiver, but this is mostly for shortwave listening and beyond the scope of this article. What Radio to Buy This is a loaded topic and one that I mentioned Ill be approaching from a handheld only angle. Im also going to keep this as budget conscious as possible, too. Like many of you that enjoy shooting, youve probably also amassed quite a collection of holsters, as you try different types out to find what works best for you. Handheld transceivers can be just as bad, but my hope is that with the info Ill be providing, youll avoid amassing a box of radios that you no longer use like I have. Some important considerations when looking at radios, are asking yourself some hard questions ahead of time. What do I want to do with my radio What frequencies do I have access to and what are my power limits on those frequencies My last article did a good job of laying out all the different frequencies available to you and which require a license to operate on. If you dont already know which of the different frequencies you want to operate on, like FRS, GMRS, or MURS, reference that first article I wrote. I hate to keep mentioning that first article, but I know there are some of you that are reading this that may think Im breezing over important topics and Im doing that for the sake of those that have the baseline info from that article. Frequency and Power. Addressing each of these questions one at a time will give you a background of what essentials to look for. What you want to do with the radio is important, are you just talking outside within line of sight of another personFRS radios are great for this application, but if distance is a concern, theyre not for you. FRS transmits and receives on UHF, which by nature doesnt travel as far as VHF due to UHFs shorter wavelength. This of course completely discounts obstacles you may encounter, which will decrease range even more. Remember that more power equals better range, so the FCC legal limit of 0. FRS is a real let down, when you can move to VHF and MURS frequencies and bump up to 2 watts of power. Pay your 9. 0 to the FCC for a GMRS license and you can transmit at 5 watts to 5. Have a HAM license That changes things too. Suffice to say, Im trying to talk you out of FRS. FRS radio manufacturers like to inflate their range, which I got into on that last article. They make claims that seem to violate the laws of physics and the curvature of the earth. What I mean by FRS radios, are the two packs of walkie talkie looking transceivers you commonly find at Wal Mart and sporting goods stores. What youre looking for in a good handheld is as much wattage as you can buy, while keeping in mind the legal limits you can operate on within your chosen frequencies. The frequency range the transceiver operates on is also very important. Obviously if your intent is programming MURS frequencies into your handheld, a handheld set up for CB with an operating range only in the High Frequency 2. MHz range, isnt going to work with MURS and its 1. MHz range. The radios Ill be recommend in this article are going to speak directly to versatility and can handle MURS, GMRS, NWR Weather and some HAM frequencies. Typically, youre only going to find a 5 watt max on handhelds, but whats also important is ensuring they have different settings for power. Meaning that they have the ability to switch between a low power setting and a high power setting. This will ensure you have a handheld that can function well for GMRS and HAM wattage, but can also dial down for operating on MURS frequencies and not violate any FCC laws. A good example of this is the Wouxun KG UV5. D radios we have here at ITS. They feature a selectable 1. W low and 5. W high setting for VHF and a 1. W low and 5. W high for UHF. By setting them to the low wattage setting, theyre able to be used with the FCC MURS requirement of not exceeding 2 watts of transmit power, yet with a programming change, they can be boosted to the high setting for GMRS or HAM frequencies at 5 watts. GMRS and HAM is obviously limited to licensed individuals only. More on those licenses and certifications here. While I could link to the KG UV5. D, the KG UV6. D is the newest version and is what Id recommend if youre buying one new. Dual Band and More. Having a dual band monitor feature on your handheld can be quite helpful. This feature will allow you to monitor two different frequencies at once. These can be VHFVHF, VHFUHF and even UHFUHF. This might be hard to understand, so Ill put it in the perspective of how weve used dual band before. During our recent ITS Muster, we assigned a radio to each of our squads and they had a designated main frequency to talk to the ITS staff on. The staff also had a frequency that wed use to talk to each other on that the attendees didnt have programmed into their radios. So wed monitor both of these frequencies simultaneously with the dual band function of our radio transceivers and were easily able to select the specific frequency we wanted to transmit back on. So in theory if the main frequency was channel 1 and our inner staff channel was channel 2, wed just have to make sure we were transmitting on channel 2 if we didnt want the attendees to hear our conversation. One more thing about dual band is that you want to ensure your antenna can support dual band as well. If youre buying a radio with dual band built in, the antenna that comes with the radio will more than likely support it, its aftermarket antennas you have to worry about. Another important thing to look for in a radio transceiver its the ability to program it manually, as well as with programming software using a cable. More on programming in the next section. What I mean by programmed manually is that it has a keypad, a digital display and that all menu options can be set with that keypad and display. The display also provides visual feedback on what channelfrequency youre operating on. A few other considerations are as follows Does the transceiver have a memory bank to store your favorite frequencies Whats the battery type Is it rechargeableIs a charger includedHome CHIRPCHIRP is a free, open source tool for programming your amateur radio.
