--- by Rick Eaton KD4HGR Well you are probably wondering if CB is still alive and the answer would be yes it is very much alive and well. You now have a new mode on CB which is now legal in the USA which is FM. The modes you now can use on CB are FM/AM/USB/LSB and the channels are still only 1-40. This is the legal stuff as stated by the FCC. There is also what is called the free bands which are roughly 40 channels below channel 1 and 40 channels above channel 40. I'm writing this to tell you about this radio called the QT40 by Radioddity. It sells for $199.99 but is on sale from time to time for $174.99 direct from their website www.radioddity.com First let me be honest and say this is a really great CB radio for your money. Its Specs are better then most CB’s as its actually a ham radio which require better standards by the FCC versus the CB Radio. It is completely software programable by your computer with the free downloadable software from the website listed above. One simple dropdown box change to CB and one simple internal jumper change from pins one and two to pins two and three you do first and it’s a CB with a lot of features. One is it has all the local weather channels programed in. It has a SWR built in that shows up in where the channel Led is It also will display frequency 2 digits at a time where it shows the channels. It has 5 different roger beeps and 32 different levels of volume for the echo and 32 different delays for the echo. When you do look at the software pay close attention to the RX and TX NR. This is noise reduction settings. Not to be confused with a noise blanker as these are too different animals. Noise reduction actually works as where noise blanker NB are usually very useless. The NR in TX is like a noise canceling microphone. Don’t change it unless you have a lot of background noise. For the RX change that as you need to if you have a good strong static noise level. I left both of mine on 3 which seems to be more than enough. I have used this at home on SSB on my HF Dipole for Ham Radio on the CB band and have made so really good long distance contacts into South America and Europe around channels 38-40 on USB. I have also used this in my car and pretty much the same results. The Noise RX works fantastic in this radio as it kills a lot of the hash noise and bring in the audio you were straining your ears to hear. Excellent on this part as we all know CB is a noisy band. This also has a VOX feature which when turned on means you do not have to push in the button but simply just start talking into the microphone but remember to turn this off when you do not want to talk otherwise everyone listening here’s everything your saying…lol Also Think about this radio in a longer term for the price you pay. If you ever decide to get a ham radio license you wont have to get a new radio as this does the ham bands right out of the box. It’s a great CB radio but an even better Ham Radio as well. This layout look very similar to the old style cobra radios like the 138 XLR or 142XLR. The specs for this radio is as follows: - Powerful Performance: The Radioddity QT40 radio boasts a 40 watts transmission power. - Noise Reduction: With both TX and RX digital noise reduction technology, the QT40 ensures that you'll never have to strain to hear or be heard in noisy environments. - Accurate Signal Meter: The PWR/RX RSSI Signal Meter provides you with a clear picture of your signal strength, helping you to optimize your communication for the best possible results. - Weather Channel: With its impressive weather band and NOAA alert feature, you can stay ahead of the curve and be prepared for any sudden changes in the weather. - Customizable Features: The QT40 is equipped with a range of features, including CTCSS/DCS, PC program, ASQ, SQ, RF gain, VOX, HI-CUT,etc. You Also get a lot of channels as you have a switch that has A thru F with 40 channels each so this gives you 240 channels which each has AM/FM/USB/LSB this is a lot of options right out of the box. For a Low priced CB compared to the others of this type and Price range you will be hard pressed to beat this rig. I love this radio and have been playing with it quite a lot as I wanted to give it a fair test out against the other out their and I would buy this radio if I dint have one already. I have run into a few truckers I know and had them play with it when its in my car and they could believe what it does for the price. So if your looking for a good Priced good quality CB versus the other Guys then give this a try as feel you will not be disappointed at all. It’s got a lot of features for the price. So give it a close look Good luck and happy Skip chasing as they say in the CB world. Rick KD4HGR

If you are new to amateur radio, you might have heard of the 10-meter band, which is one of the most popular radio bands. But what is a 10-meter radio, like Radioddity QT40, and how is it different from other radio bands? In this blog, we will discuss everything you need to know about the 10-meter radio. 1. What is a 10-meter radio? The 10-meter radio is a type of amateur radio that operates on the 28 MHz frequency band. It is a high-frequency radio band that allows for long-distance communication, making it popular among amateur radio operators who want to talk to people from other parts of the world. 2. What's a 10-meter used for? The 10-meter radio is mainly used for two-way communication between amateur radio operators. It is used for various purposes, including talking to people in other countries, participating in contests, emergency communication, and experimentation with different modes and equipment. Talk to other amateur radio operators: One of the main reasons people get into amateur radio is to make contacts with other operators around the world. With a 10-meter radio, you can communicate with other operators using various modes such as SSB, AM, and FM. Participate in contests: Amateur radio contests are a fun and competitive way to test your skills and make contacts. There are several contests throughout the year that focus on the 10-meter band. Experiment with antennas: Antennas are a critical part of any radio system, and experimenting with different types of antennas can help you optimize your setup for better performance. With a 10-meter radio, you can try out different antennas and see how they affect your signal. Explore digital modes: With the right equipment and software, you can use your 10-meter radio to operate in various digital modes such as PSK31, RTTY, FT8, and JT65. Help with emergency communications: In times of emergency, amateur radio operators can be called upon to provide critical communication services. With a 10-meter radio, you can be part of a local or regional emergency communications network. DXing: DXing is the art of making long-distance contacts with other operators around the world. With a 10-meter radio, you can try to make contacts with stations in other countries and earn awards for your achievements. Experiment with different power levels: 10-meter radios usually have adjustable power output levels ranging from 1 to 100 watts. Experimenting with different power levels can help you understand how they affect your signal and reception. 　 3. How far will a 10-meter radio transmit? The range of the 10-meter band can vary depending on a number of factors, including the type of antenna used, the power output of the radio, the mode of transmission, and the conditions of the ionosphere. Under normal conditions, the 10-meter band can typically support communications over distances of several hundred miles (or kilometers) using SSB voice or digital modes such as RTTY or PSK31. With good propagation conditions, such as during peak solar activity periods or during Sporadic E propagation events, communication distances of over a thousand miles (or kilometers) can be achieved on the 10-meter band. Ultimately, the range of the 10-meter band is highly dependent on a variety of factors, and can vary widely from one situation to another. Amateur radio operators should always use good operating practices, make responsible use of their equipment, and operate within the limits of their license and local regulations. 4. Do I need a license to operate it and are there any privileges and restrictions for each class? Yes, you need a license to operate a 10-meter radio. The Federal Communications Commission (FCC) regulates the use of radio frequencies in the United States, and you need to pass an exam to obtain a license. There are three levels of licenses: Technician, General, and Extra. The Technician license allows you to operate on the 10-meter band, while the General and Extra licenses allow you to operate on other frequencies as well. Technician Class License:Technician class license holders have operating privileges on the 10-meter band from 28.000 MHz to 28.500 MHz. They are permitted to operate on all modes of transmission that are legal for amateur radio operators, including voice, digital, and CW (Morse Code). However, they are limited to 200 watts PEP output power. General Class License: General class license holders have expanded operating privileges on the 10-meter band, with access to the full band from 28.000 MHz to 29.700 MHz. They have the same operating mode privileges as Technician class license holders, but with a higher power limit of 1500 watts PEP. Extra Class License: Extra class license holders have the highest operating privileges on the 10-meter band, with the same privileges as General class license holders. They also have the highest power limit of 1500 watts PEP. It's important to note that these operating privileges are specific to the 10-meter band and may differ on other amateur radio bands. It's also important to be aware of any frequency allocations, band plans, and operating protocols that may be in effect on the 10-meter band or in a particular operating region. Amateur radio operators should always operate within their license privileges and comply with all regulations and guidelines set forth by the FCC and other governing bodies. There are no operating modes that are specifically reserved for a particular license class on the 10-meter band in the United States. All licensed amateur radio operators are authorized to use any operating mode on the 10-meter band, including voice, digital modes, and CW (Morse code). However, it's worth noting that some digital modes may require higher power levels than what is allowed for lower-class licenses. For example, the JT65 and JT9 digital modes may require up to 1500 watts of power for reliable operation, which is only allowed for Extra class license holders. So while all license classes are technically allowed to use these modes, they may not be practical or effective without the appropriate license and equipment. In general, the operating mode that a user chooses to use on the 10-meter band will depend on their personal preferences and equipment capabilities. Some popular modes on the 10-meter band include SSB (single sideband), FM (frequency modulation), and various digital modes such as FT8 and PSK31. 5. What's the most popular mode for a 10-meter radio? A 10-meter radio supports several modes of operation, including SSB (Single Side Band), CW (Continuous Wave), AM (Amplitude Modulation), FM (Frequency Modulation), and digital modes such as RTTY (Radio Teletype), PSK31 (Phase Shift Keying), and FT8 (Franke-Taylor design, 8-FSK modulation). The most popular mode for a 10-meter radio is Single Sideband (SSB). SSB is a voice mode that allows for clear, high-quality communication over long distances. Unlike AM, which is the other common voice mode used on 10-meter radios, SSB provides more power efficiency and better audio quality. This makes it ideal for long-range communication, especially in challenging conditions where signals may be weak or prone to interference. Another reason why SSB is popular on 10-meter radios is that it allows for a wider range of frequencies to be used within the 10-meter band. SSB signals can be tuned to occupy just a few kilohertz of bandwidth, allowing multiple SSB signals to occupy the same frequency range without interfering with each other. In addition to SSB, other modes that are popular on 10-meter radios include FM, CW (Morse code), and digital modes such as PSK31 and FT8. Each mode has its own strengths and weaknesses, and choosing the right mode for a particular situation depends on factors such as the distance between stations, the available equipment, and the operator's preferences and skills. 　 6. What's the difference between 10-meter radios and CB radios? While 10-meter radios and CB (Citizens Band) radios (like Radioddity CB-27 Pro) may look similar, they are designed for different purposes and operate on different frequency bands. Actually 10-meter radios are not designed to communicate with CB Radios. Here are some key differences between 10-meter radios and CB radios: Frequency range: CB radios operate on a narrow band of frequencies between 26.965 MHz and 27.405 MHz. In contrast, 10-meter radios operate on a wider band of frequencies between 28.000 MHz and 29.700 MHz. Power output: CB radios are limited to a maximum power output of 4 watts for AM and 12 watts for SSB, while 10-meter radios can output up to 200 watts of power (for Novice and Technician classes). Licensing requirements: In most countries, CB radios can be used without a license, while operating a 10-meter radio requires a valid amateur radio license. Modes: CB radios are limited to AM and SSB modes (and the newly added FM), while 10-meter radios can operate in a wider range of modes, including FM, CW, and digital modes. Antenna requirements: 10-meter radios have a shorter antenna length. CB radio antennas are a bit longer. Without considering other parameters a quarter wave antenna for 10m is 2.50 meters long and for CB the same quarter wave antenna is 2.75m long. Both of them must be tuned with an SWR meter and have its SWR set for the closest ratio to 1:1 as possible to work properly. Range: Due to their limited power output and shorter antennas, CB radios have a shorter range than 10-meter radios. 10-meter radios can make longer-distance contacts, especially when using SSB mode and a high-gain directional antenna. Use cases: CB radios are commonly used for short-range communications between vehicles, while 10-meter radios are primarily used by amateur radio operators for long-distance communication and experimentation. 7. What Antenna should a 10-meter radio use? The type of antenna you use with a 10-meter radio will depend on the mode of operation and the location of the antenna. For general use, a vertical or dipole antenna is suitable for a 10-meter radio. A beam antenna is also an option for those looking for directional capabilities. Conclusion In conclusion, the 10-meter band offers a unique and exciting opportunity for amateur radio operators to communicate over a range of distances using a variety of modes and frequencies. Whether you're interested in voice communication, digital modes, or CW, the 10-meter band has something to offer for operators of all license classes.
