There are many myths and misconceptions in radio which are factually untrue. Reflected power is due to an impedance mismatch at a point in a circuit. A main issue in antenna systems is loss in the feedline. One very common misconception is that "high SWR damages the transmiiter". This is not true. The output circuit of a transmitter has an impedance matching circuit to match the low impedance of the output transistors to the higher impedance feedline. Reflected power arrives at the transmitter output and gets reflected again so that it is now in phase with the forward power. The aggregate effect is that most of the power produced by the transmitter will get radiated. The main factor of antenna performance is not SWR. With a perfect SWR (like you would get with a dummy load) you will still have feedline losses with coax. Some are better than others. To state that SWR above 1.5:1 will damage the radio is simply incorrect and promotes the misconception that SWR is enemy #1. I recommend every ham get a copy of the ARRL Antenna Book and read it. Another excellent book on the subject is titled Reflections by Walter Maxwell, an RF engineer who designed antenna systems for a living. It is a free download.

What am I looking for that would signify it’s bad? Too high Ohms?

Best video on the subject I’ve seen!!

Is there a lockout feature on this light?

Great information. Thanks for sharing and also for putting up a webpage with the charts that you use.

Best explanation for on the GMRS waivers/conditions I have found.

link to the chart?

Ahh I see now why many radio operators damage there Nano meter

thank you so much this was incredibly helpful information you have no idea

what was your range test at

sorry pal G M R S has two different power 5WATT on hand held's and 45 watt on base

G M R S is 5 watts on portable and my base is 45 watts and requires a license for that 35.00 covers all family members and last's 10 years which is on my F C C license and my call sign is W R X N 824. and I talk to Chicago twice a month on a lower link,

i made a yagi from tape measures and did not measure anything. just eyeballed it. a signal came out when i put the baofeng on it. its mounted on my roof now and is continually transmitting dead air to the local repeater.

HOW DID YOU TUNE THE ANTENNAE

there is no 50 channels in are radio's

Do i need to get a FCC license for a gxt midland radio model gxt1000G

Wjat does all the power high low for?? Im new at all this

Where does the 2.5 multiplier come from?

I have the same antenna and similar set up but I have to keep it much lower because of my HOA... Do you see any issues if my radials extend under my soffit and gutter? They end about 6, inches from the brick on my house. Will this cause any issues?

Instead of Wouxun software, try Chirp Next with KG-UVD1P settings. The freqs won't default back to factory. The 805G GMRS model can be programmed similarly.

Note that the Wouxun KG-805M radio has a channel numbering system that is different from many other MURS radios (e.g. Btech MURS radio). Wouxun's channels 1 and 2 correspond to 154.570 MHz and 154.600 MHz, respectively. On business radios, these channels are known as "Blue Dot" and "Green Dot" channels, respectively, and are more likely to be used by nearby businesses. So it would be more advisable to rotate between channels 3-5 (not 1-3) on this particular model. In contrast, on the Btech MURS radio, the "dot" channels are channels 4 and 5, and rotating between channels 1-3 would make perfect sense.

Thank you for this.

Thank you for the video! I see your radio is programmed for wide band. In this regard, I have a question. When you push the PTT button, does the "N" icon still appear on the screen? My 7D has two W/N band selections. One for RX, and one for TX. I put both on wide from the front panel. There is no "N" icon. But if I press the PTT button, the "N" icon still pops up. Do you know how to program W on TX so that it sticks? I tried to do it in channel and vfo modes, but to no avail... Some software maybe?

Thank you a very clear explanation !

I’m so confused…I can’t do a simple thing like contacting my second walkie talkie 😢

This is ok for people in the USA where FCC rules apply, but the rest of the world has different rules. In most of Europe, Asia and Africa for example, there is a legal requirement to ID at the start of every conversation and then at 3 minute intervals at least. Not all of us are Americans. ;-)

Thank you for this, I didnt want it to be true being in Seattle area, but this confirms my suspicions.

Issac is that you?

OK, so SWR is a measurement of reflected power; so how and why is the power "reflected". Yes, I know it has to do with tuning the antenna so that the impedance matches between the antenna and the radio, but more directly, WHAT reflects the power, and how does tuning the antenna to its resonant length prevent that? Would installing a resistor at the ends of the antenna prevent this reflection?

How do you add frequency’s to it?

Cos my field is in computers, i have some idea, , your wondering, what the hell is an SWR, SWR stands for "Standing Wave Ratio", the transmitting signal travels along the antenna (FORWARD) and refects at the end, returning down the antenna (REFECTED), the forward signal interferes with the reflected signal causing constructive or deconstructive interference, differant lengths create differant phases along the antenna, when a peek meets a peek there is max emission, and when a peek meets a trough there is zero emission, an SWR ratio of 1:1 is perfect constructive interference, where the cycle appears STATIONARY on the antenna, creating a perfect waxing and waning electo-magnetic field, as the electric field collapses, the magnetic field increases and vice versa, , ,Without that load absorbing energy, the energy instead appears as a high voltage or high current somewhere which may not be equipped to handle it, , So basically, an ideal 1:1 SWR will produce a low 50ohm resistance match where the antenna does work, the SWR is relatively constant along the feedline, the impedance will vary along the line unless it is perfectly terminated (that is, the SWR is 1.0 : 1). This is an important concept for impedance matching, because with a high SWR, the impedance at the final output transistor load inductor could be mainly higher, or lower than 50 ohms, and produce a high current that damages the finals, , ,

Program it on chirp as an RB27 instead of an RB27v. The results are surprising!

COMPLETELY confusing "tutorial". Not informational at all. This video seem like it was made for people who already know how to use this device, not a new buyer.

where is the combo tool phillips on the 58mm knives ? You are fired !!! Hand your SAK card in to HR

I was using chirp to program my RB27b and RB27v radios when I noticed that chirp had a “full band support” for both radios. I gave it a try, and was surprised to discover that it gave both radios 99 memory slots, with full uhf/vhf functionality. I have plenty of other radios with that capability so I didn’t re-program them, but it is fascinating what can be done with them. The entire RB27 line has evidently been dropped. That is unfortunate. I have all three flavors, and they are my favorites!

Good luck using the earbuds/"headset". You might have included how to put the damn things in your HEAD!

I will say this... most of the ham videos on the interwebs talk in so much code... that i think they forget there are people who know nothing about the hobby (me) that are trying to learn. So when somebody breaks down definitions (and more importantly, functions and practical applications)... i get jazzed. So thanks!

Thank you... It's good enough for me to be happy... I'll keep looking for more. I'm bit nerdy.

THIS GUY IS WAY OFF!!! dB IS A LOGARITHMIC SCALE NOT A MEASUREMENT!!! dB ON AN ANTENNA INDICATES ITS RADIAL PATTERN FOCUS. A POSITIVE dB NUMBER ON AN ANTENNA DOES NOT AFFECT THE ERP!!! STOP MAKING VIDEOS!! YOU'RE TEACHING PEOPLE HOW TO BE STUPIDER!! STOP IT NOW!!! YOU WILL ALWAYS HAVE A LOWER ERP THAN THE RADIO'S OUTPUT DUE TO INSERTION LOSS FROM CABLE & SWRs. YOU SHOULD SMACK WHOMEVER TOLD YOU TO MAKE VIDEOS FULL OF LIES!! IF YOU HAVE A FUNCTIONING BRAIN CELL LEFT IN THAT ROCK YOU CALL A HEAD, REMOVE THIS BULLSHIT VIDEO!! A$$___E

New user manual shows CTCSS/DCS privacy codes for Midland GXT1000 series 28 extra preset channels.

It’s actually right above the 2 meter ham band so it’s going to behave like this 2 meter 144 to 148 MHz band. So if 2 meters is open, murs just might be too. It’s basically ham radio, but without the requirement for a license. I don’t recommend using a ham call sign down there on murs or anywhere for that matter.

They come in a 3 pack and 5 pack. they do program chirp . you get great range with Abbree 771 antenna . that tune 150 MHz and 460 MHz . also the 42 in Abbree works on them. got several miles between the 2 on Ch 4 wide. could not do on stock antenna . will USB C solar panel charge. or a power bank with USB A to C or C to C cable. my outher radios like that are the RB 27 GMRS and RB 27B FRS . can use MURS and FRS same time on 2 different radios buy each outher. even CB . the only issue we had is when using same band and different Ch when close but a outher person it cuts the receive out on outher radio . only happens when close to a outher radio on the same band.

The Alinco DJ-VX50t has the same antenna configuration as the FT65 and Baofeng. The Alinco also has a very nice sounding and very loud speaker. I would like to compare it to find out if the direct conversion reciever can hear as well as the old double conversion superheterodyne recieve in the ft60r

No it is not important to only check VSWR at the radio. You should check it at the antenna with a VNA, yes you should have a radio meter 99% have one in the radio. But checking VSWR after a a long run of coaxial cable is false as the coaxial cable absorbs some of the reflected power as coaxial cable loss. Infact you can add coaxial cable length to soften the reflected power if you don't have a tuner but this will lower your ERP.

I just got my ssm-512. The burst of static into my ear at the end of each received signal is nearly unbearable. Is there anything that can resolve that?

How did you tune the antenna

I just ordered 3 of them for $25+tax about $9 each.
