- เผยแพร่เมื่อ 25 ก.พ. 2023
- In this 6th video we look at different power CB AMPLIFIERS and the pro and cons of running power on CB radio. My advice is before you look at increasing your power output consider spending the money improving your antenna set up. Also the large RF amps may cause interference with neighbours etc. Something to consider before you click to buy.

I have used hf radios on 11m for approx 40 years,good filtering,vfo and 100w working the world using a good well situated vert antenna...10/4 73
Hi Fred. You are right about getting the right antenna and improve the entire setup before using amps. My experience shows that having every step of your radio setup goes a long way to achieve excellent range. We do have an amp, but hardly ever use it. We tried to get things right a legal as possible here in Ireland. The endresult was a Lincoln 2, feeding into a COMET300 tuner, next step can be the amplifier or without, then feeding into a Low Pass Filter and from there of it goes up to a Gainmaster. All cables, including all patch leads are made from RG213. The SWR is 1.1 -1.2 over the entire spectrum. With this setup it is sometimes hard to say if a 203P really does deliver much more in reach. I believe in spending money on an top of the range antenna tuner, the best cables and overall in good equipment. This way a "burner" is hardly ever necessary, you can go to far away places! I think we have only once or twice used it. Overall I think it is perfectly possible to stay closer to the "legal" side of things by making the most of what you have without needing burners etc. It is important that you also give your power supply a plus tolerance of +10Amps above max power needed, don't use you power supply flat out. Once a power supply is "driven" to max the overall Quality of your Signal can deminish.
Totally agree with you.
Voltage drop is the killer when you start sucking amps at the limit , volts drop hurts things too.
Long time ago i use Zetagi BV131 valve amp. It brings a good clear signal and high voltage. Was a good thing. Tea always hot. 🔥
What you said: Good antenna does most of the job. And make sure your antenna has a good swr. That's the basic stuff and to me the most important. With a good antenna you increase your gain much better then with adding more power. Power is nice but not always the key.
Spot on.
Hope you still monitor these older posts. it's 4/9 2024. Enjoy your posts and videos. Great advice and you make it interesting and easy to understand.. Been out of the radios since the early 90's but I am diving back into the pool. Setting up the truck then a home base as the year progresses. Thanks for what you do
Nice one. You will be set up for the summer skip esp if you choose a SSB radio.
@@CB-RADIO-UK Thought I posted.....disappeared. Which would you suggest for power supply in truck? Cigarette lighter port or a fuse piggy back? Uniden BC 8800
Check your 12 volt amp rating. Should be ok if its 20 amp.
Why not keep them all? They all have their place in Communications. Love your channel Fred!
Well said Fred as always , the video was fully comprehensive & very helpful , thank you .
Glad you enjoyed it
Good video, i really like the way you have your equipment mounted, it looks neat and clean looking.
Thanks!
Thanks Fred. Good info for newbies. I have been a licensed amateur radio operator in USA for decades now. The antenna and feed line ( coax) are going to give your station the best benefit for improvement of performance. If you already have a high quality performance vertical antenna and you still believe your not satisfied. Then a directional beam antenna is a good way to make a huge improvement in both receive and transmit as well.
You can build a basic qubic quad antenna with simple PVC plumbing pipe and 2 14 guage semi loops of copper wire. Use an RG-8 with foam insulated rather than the popular RG-8x which is a much lower grade coax cable with higher loss problems. If your operating is home base then RG-8 foam is a great way to go. Couple that improved performance feed line coax with a simple 2 element quad antenna and you will be amazed at the difference and your still at legal rf wattage transmitter limit. Add a small amp along with a low pass filter and it should perform well.
73 and GOD bless. K5ewm.
Frid in the shed your utube videos are awesome 👌 👏 👍
great video. same hear in the US. CB picking up. I have talked all over the world on CB and HAM. portable is big in US . the CB is between 2 ham bands. 10 and 12 meters . most ham antenna's can be tuned for 11 meter CB . even the end fed dipole 1/2 wave wire antenna. just change the length of wire. and if using big ferrite core like a T 240-43 or stack of 2 or 3 can run some power .what I do is string it up a fiberglass pole like the DX commander pole. lean it into a tree and talk skip. even on CB . or the outher way I do. ferrite on table or to a tent stake and wire to a fiberglass pole. about a 45 deg slant. works great. RM Italy has nice amps. now 24V ones. KL 805 . 600 PEP SSB with a ICOM 705 10 watt drive. well my meter shows around 500 watt PEP . and ran on 2-12.8V 50 Ah LiFePO4 battery's . easy US to UK gray line skip. from in a park and all on battery . got one of them antenna kits . just cut wire for CB. 1.2/1.3 SWR . Italy makes great coax as well. M & P . using POTAFLEX 7 50 ft coax. spend money on better antenna and coax and radio first. even the DX commander antenna can be cut for CB . works super. best thing for them amps. keep drive down . keep them cool . some have fans on them.
Frid in the shed I learn lot from you about CB
This person who sold me the amplifier said that when he used it, all the neighborhoods tv was shutting down because it was so powerful. Idk if that’s true or not but when we connected this to my radio the fuse did blow in the amplifier. Thank you for cb radio video 😊
Did you buy the anytone 6666? That may have too much drive for a small amp
@@thesuccessfulbarber Yeas I bought that one 🤩
Long ago and the dark distant past of analogue CRT televisions there was a potential for TVI as the unshielded internal oscillators of the televisions would be very close in frequency to CB operating frequencies. This combined with a poorly manufactured/set up/installed/filtered linear amplifier could mean that all the neighbors TVs would go out every time you keyed up. Since the advent of digital TV and the demise of the CRT this is far less likely to the point of being, for all intents and purposes, no longer a problem.
I'm fond of my KL703 and KL 503 HD. Good little heaters.
Also good for toast :-)
A low pass filter is a must with these amps as ,they have no output filtering inbuilt.
👍🏻
Nice upload Fred.
Yes thats a good shout as the cheaper ones do splatter.
I got an RM KL35 recently and it actually recommends using a low pass filter with it, which I got from Zetagi. I checked the circuit, which they supply online, and there was indeed no low pass fliter in it. These things all produce loads of harmonics on higher frequencies. So say a big "hello" to the police, fire-brigage, ambulances and everyone else who lives up on those harmonic frequencies :D
@@SimonBlandford police, fire-brigage, ambulances use tetra digital trunked radio system so no way into that system.
@Chris van de peer if you calculate third harmonics from 27Mhz yes it 54 Mhz so big yes to low pass filter.
@@M7XCB 6 meter band and aircraft band 136mhz yes, Maybe the start of the 3 meter band 88mhz but not a trunked system like the police have in the UK.
Homebase I use old Bremi BRL210s - they put out about 80 watts FM with 4 watts in, gets me everywhere I need when the lift is on.
Yes i rem Bremi amps.
Great video! There are many factors to consider that are more important than just power. Power is overrated. Antenna, antenna location, SWR and a good cable are critical. Putting out a lot of watts does nothing except annoy people. In addition, unless you have matching sensitivity on the receiver you won’t hear people trying to contact you. Keep things in balance by sticking to basics.
Yes totally agree. Always work on your antenna and set up first. Get that right and you prob do not need any extra.
Fred in the Shed thanks for the review of the amplifiers!!!
If you start with 10W and a received signal of S5 and increase your power to 400W, that’s a gain of 16dB which will take your signal up to just over S7.5.
Higher power costs a lot yet provides far less gain than most new amateurs understand. Invest your time to improve your antenna system as much as you can and the results will be far better. Your reception is very likely going to improve as well.
Spot on. Antenna and coax first.
Thumb up fred
12:25 Minimum power on the Yaesu FT-450D is 5W.
You talking about people can hear you but you can´t hear them, well, but you did not mention that the KL300-P has a built in Preamp that puts on another 25db on the receiver to be able to hear people better. All RM amps that ends with a P has this built in preamp, it actually works pretty good. I do agree that you gotta put your money on a great antenna and cable first, and tune the antenna to the best possible. in my opinion if you´ve done all that an amp with a preamp can help sort out some of the problems if your house is located in a bad spot or something like that. Thanks for the video... :D
Thanks for the comment. Yes your correct some amps do come with a pre-amp. However ive had them and in reality they just increase the noise level. Without dsp they are almost useless. More on the subject here. th-cam.com/video/0czQFv5zdCY/w-d-xo.html
@@CB-RADIO-UK Yeah you are right but i think the preamp works pretty well in some cases, depending on the signal.
Today you have rf gain in radios.
I have my old and trusty TS-450. My radio is 100W rated but i don't think it does that. Its closer to 50W FM and perhaps 70W SSB but it's fine.
Hi Fred, I am watching your videos as I have a slight interest in returning to CB radio, so thank you for this run of videos, I was a child of the 70s, older brothers had CBs, all American AM at that stage and I had a home base in my bedroom. I lived out in the countryside at that stage so putting up an 18 foot Di pole was no issue and noise was minimal . Now I live in town so this will be much more difficult
My favourite CB I had was a Tristar something or another that had SSB etc, then FM was made legal and things seemed to all go down hill for me
One thing you have not mentioned here and does interest me is back then everybody sat on 14 or 19 which was mainly for truckers and then moved away to another channel, is this still the case?
Thanks again for the videos and I will be going through many more as I research my return to cb radio
Hi Andrew. Hang out Channels depend on area. Around my QTH channel 19 is used for everyone. Channel 14 is no longer used. Move up the road to North London and they hang out on channel 35. I think in general channel 19 is the most popular on UK FM.
14 was AM back in the day , 19 was a FM thing . Anyway they are the open or emergency channels, you should call whoever you are trying to contact then move to any of the other 39 channels that arent busy , turn your power down if you are close enough , keep the airwaves clean . On VHF marine 16 is the open/emergency channel .
703 is fantastic...just run 35 watts....
Hi there great video as always what you said was so truel have a ax144 sideband and my antenna is inside a helical whip on a steel box and a counter poise wire as a ground l can hear distance stations but cant work them more power is not going to help l need to put up a 5/8 ground plane or a or a lafayette half wave ground plane or a station master antenna about 30 feet high then l dont need any more power yes you are so right overseas skip stations you need a good outside base antenna the higher the better cheers l am from melbourne Australia101 melbourne
Gday :-)
Some use them...NOT ME...haha that cracked me up 😉
Apart from the best antenna you can afford it’s also important to get the best coaxial cable and add a choke,conditions are on the up so more power is not always the solution as great dx can be worked on low power.Cheers Fred 73s 108at176 Chris
yet most idiot CBers use RG58 or Mini8 and a crappy A-99 and then stick a KL-503 and wonder why they cause so much dirt and can't hear anyone :)
Whats your thoughts on Ultraflex ?
@@CB-RADIO-UK I use ultra flex 7 Fred and on hf I find it’s excellent,also perfect for use with the rotator as it flexes perfectly
I don't agree with buying expensive coax for hf. A transmit power of 50watt through 30mtrs RG213 your loss is about 6.5 watts the same through LMR400 is about 7.5 watts. so at 50watts to gain 1 s point you would need to transmit at 200 watts 4 x in the input power 6db equal to one s point. so losing 6.5 watts on 30meteres of coax isn't noticeable. this hi spec coax is really designed for vhf and uhf and people that have big pockets and lack knowledge of how radio works. the spec can change on the cable you buy but they are printed on the cable and on the sticker on the drum. a simple calculation and you can work out what you need to know. a low pass filter is a good idea and no one mentioned a rf choke to stop common mode this stops the coax radiating and causing inference. Bin the tuner and use a resonant antenna which will radiate properly to the frequency your using.
@@grandpaandlucas7054 ultra flex 7 isn’t expensive and as I said it’s very flexible which is perfect for using with my rotator
Your learning Fred. Spot on the antenna is the best upgrade to your station. Had some bad news this week my display has gone down on my grant 2. So if any body has a grant 2 for sale or a donor grant 2 for parts. I'd be happy to hear from you. Cheers Fred great video. Keep up the good work.
You're learning, Fred. You're - which is the contraction of "you are" is what is used here. Now your learning (as in the learning that belongs to you, since your is possessive) can be improved if you learn this difference. Also, the word donor doesn't have an E in it unless it is a bloody kebab! 😁

@@CB-RADIO-UK quite right Fred. He lives on own and has nothing else better to do then troll others. I won't comment again but then it spoils it for your posts. Which we all enjoy watching and commenting on. Keep up the good work Fred.
4 Watts by a CRT Alpha or my President Truman let me work Europe and Russia and local stations can still hear me in 50 km distance (78m over ground underneath Dortmund Airport). My antenna is a full size 1/4 Tank Whip in only 3m hight on a bungalow. I dont need any silly amplifiers which only brings trouble. Many amateurs also dont need more than 4-5 W when they go QRP worldwide sucessfully.
What band were your contacts ?
@@CB-RADIO-UK CB only. Last connection was to Ramon (50 DW 01) 600km south of Moscow and a german holiday station in the south of Portugal. 2500km and 2000km from my QTH. 4 W and Tank Whip!
@@MrBSD-vq5yp We did speak with a contact about 2000km away in south Finland with a 4W CB radio and a long roof antenna. But that was 30 years ago before the Russians started sending with what I assume is 100.000w on all frequencies all the time day and night making the CB radio totally useless unless you also had 100.000w +++ ...

Thank you Fred. I’ve a President George 11 with a thunderpole 5. I’ve got a 2 three amp inlets on the power supply at front and I’m using the back to power the cab. Can I use the front two in lets to power the amp? Thanks Phil
It’s a RM 203p !
Upgrade ant. ? I have a small magnet mount for regular , w/ linear 60 max AM.. have a larger full wip or loaded larger ant. Only 27 on the cb 11 meter that works. And a larger tripod or moonraker for base the same, and less than half on mic gain. Or modulation boost and over 60 watts will nock you off. Burn up usage.
Off the tangent…but do you still use the shine armour…. It gives a great shine .. ( i got some after your review and recommendation )., if the same was done in colour waxes..( the application process ) it would be great… but really good product……keep it up..
Hi Tim. Yes i still use Shine Armour on our fiesta. Ive tried other brands of spray ceramic but ive come back to it. However ive been very impressed with the Avalon King product. Expensive but i will be using that in future. Amazing results on my old car. See here th-cam.com/video/EIww8FerMmc/w-d-xo.html
EFLW for 26.695-27.99125Mhz might be the way to go.
I not using amp anymore It was causing the tv indoors to loose signal, I have cb setup in shed. The amp has preamp for receiving I found the preamp does not really improve. I guess best to keep it legal with the 4 watts.
You can still do a lot of local work on just 4 watts.
Hi. Great video. Will you be making a video of a receiver. Forgot what they are called but instead of boosting your signal it brings others in. Thanks
Do you mean a Preamp ? Here th-cam.com/video/0czQFv5zdCY/w-d-xo.html
@@CB-RADIO-UK hi. Yes
They are called pre amps and if you get any interference issues all a pre amp will do is increase your interference problem. If you don't get interference now you might if you connect up to one. Best thing for receive is a " loop on the ground" aerial on a twin VFO HF radio.
You used to purchase a Linear Amplifier that used a Line Timebase tube but you had to build it yourself.
I once tried a Zetagi B550P. I wasn't that impressed, as it wouldn't do more than 240W PEP. Expensive, for what it is. The B300P did just over 120W PEP.
You'll get 300 from a kl503, and there only £250 when bought from Italy, £340 to buy in the Uk
@@EdzashedFudwinkleI built a homebrew linear amplifier that does 350W-400W, for about £300.
my burner is the same as the blue one KL 203-p
Only against the law if you comply with the law😂
I used to run a ham jumbo with a bremi brl200 linear running though an avanti sigma 2 back in the 80’s and wiped out most of the tv’s in our street so usually had to do Sunday morning dx when no one was watching Corrie on the telly😂
I do agree with regards a hf set and a widebanded yaesue or icom will always be a better quality unit than a plain old cb radio running an amp..
hi fred having watched a few of your videos now I've got a thunder pole t800 cb and a 5-7 amp power supply im using i think its rg58 cable. and a thunder pole 1/2wave antenna around 4mtrs up to the bottom of the antenna im hearing local lads in london on fm and can hear lots of foreigners from abroad on am but like u say im billy no mates no one can hear me. what am i doing wrong😌 it doesn't help im a slow learner lol cheers 👍
Its good your hearing signals. I was in this situ myself when i started. Its most likely the people you are hearing are running power so have a greater range than yourself. First thing would be to check your SWR and try to get it as low as possible. The 1/2 wave with a good SWR should get out well even on 4 watts. If still no luck you may have to consider running a small amp.
Cheers Fred my swr is low it hardly registers on the meter
@@gibbosj08
Get your aerial up to about 30-35 feet above ground level (AGL)
Because your aerial is that low you are transmitting what is called "NVIS"( near vertical incident skywave).
That means the best of your signal is going nearly straight up and nearly straight back down.
Getting your aerial UpTo 30-35feet AGL will make it radiate better towards the horizon instead of being a "cloud warmer".
I hope this has helped.
🇬🇧👍😎👍🇬🇧
Good advice spend money on your Aerial and coax system and put outside aerial I am a licensed Radio Amateur you can spend a lot of money on Amateur Radio set no good if do not spend money on your Aerial and low pass filter is a good idea when using RF Amps I still why do not get you Amateur Radio Licence The Foundation Licence 10 watts digital modes contact you can do the test online now
Fred, using a 100w Hf radio on 11m is illegal, so is using a converted 10m radio doing 30/40w, bit saying that I also have 2 kl503/505v, for Ssb 11m, currently contemplating a 703 & 75amp psu
Wow thank you ! All this time and i never knew that. Best of luck bud.
How do you match the amplifier to the radio. Is there a 80% or something of the antenna. You want the antenna to have just a little bit more power handling than the amp
Not quite sure i understand. Most antennas can handle 500w + All antennas are 50 ohm so match the radio.
For mobile using one of these RM KL203 I need to use the AM Mode for FM, I suppose?
Yes AM for FM. SSB is a longer delay on the relay.
I have a rm Italy kl203 and a cobra 29 and with both on and when I key up the mic and the radio receiving will stop like normal and no noise then when I let off the mic nothing no noise or receiving . I have to turn the amp off to receive on the radio again. Can you help???
Yes. It sounds like the relay in the amp is sticking. You should hear it click over when you de key. If you have the switch set to SSB there is a longer delay on the relay. If your using FM make sure its set to the AM setting.
Do one on tubes…..
Hi Fred in that shed do you still use the antron 99 ? Will you ever upgrade to the sirio gainmaster or be upgrading anything for future videos ? Thanks
Hi Steve. Yes the A99 is still in use. Prob only upgrade it when it fails. Next one will most likely be a Sirio 2016.
@CB-RADIO-UK I've just taken down a sirio 2016 and put the gainmaster back up. My write up on my QRZ page might help you understand why search for M7WLG on QRZ. The gainmaster has a perfect SWR 1.0 -1.1 right through CB bands and 10m band it's a pre tuned antenna you just put it together and it's perfect.
@@CB-RADIO-UK this antenna is bad in strong wind. Loose radials and you must weld on ground angle flat steel. Better buy a sirio blizzard 2700
can I mount my antron 99 in a tree when I'm camping? and what batteries can I use in the field?
Hi. In theory you can put an antenna in a light tree. People have done it. You would just need to check the SWR to make sure its at a safe level. Some people use a cheap 12 volt leisure battery and other use expensive lithium iron. If your running legal amounts of power you should get good run time from a smaller 12v battery.
Frid in the shed Iam thinking about getting a hand held CB am fm with ssb
Does anyone know the specs of the B150 shown by Fred?

That's because you overdrive it,these amps do fm fine
I cant possible my antenna above myn own roof ! It’s impossible where I live
Yet with the little kl203p I get more in and out
So,even with a bad antenna situation these have a pro
First I Will see if I can get a 6meter pole instead of my 4 meter pole
Saving for a Kl703 or even better the Kl805 wich has low pass filters and swr protection build in. But boy, my biggest wish is to simply have an antenna above the roof. I wouldn’t even want a burner then. The “export “ radio’s have pwr enough for that.
If your spending out on a Kl703 i would consider a used HF radio.
How come you didn't mention the big boy amps like Fat Boy, 307, Skullcracka, Carlbuilt, Wizardbuilt, etc? Those are the big amps.

Yep.
Cb linears are legal in US. Can be used in ER, shoot skip, ch 9 monitors. Power outages.
Cb linears are ILLEGAL…. not legal. Not sure where you are getting that they are legal. That said, lots of folks use them without problems. Never heard of anyone getting in trouble for one.
FCC rules state Strictly on CB radio in USA. A CB radio operator may use a mobile or base station to have a linear to contact during an Emergency and in Catastrophy or Riots or War Time or to shoot skipland in a situation to send information long distance or CH 9 Monitor.

Sounds like you will be having some radio fun. Should get plenty of skip coming in on AM and SSB this summer.
Worth pointing out it's not unlawful/ 'breaking the law' it is breaking the rules. Legislation is rules and regulations, not law, and require contractual agreement (can be argued includes tacit agreement). The overall fact is that the equipment is yours and to take it from you without your permission is theft, that most definitely is unlawful.
Interesting point but if they wanted too or if they had the funding to do so iam sure ofcom could take my equipment and fine me.
The autorities can and will take it away form you if they think you have broken the rules / laws, I have learned that the hard way myself... And even if you have the law on your side it does not matter if the corrupt judges is of another opinion.

Take and pass the Foundation,General and Technician then you can get yourself a nice transceiver.
I could but i already own some very nice HF transceivers.
Your reading that input wrong,if you put a 20 watt dead key into a 203 it will blow up on day 1
Adding a linear/burner to your station is at best cheating and at worst. Going to get you into a lot of trouble.
Height is might. Adding power is just shite!!!
Get your base station areal UpTo 35feet AGL for TX and a loop on the ground for Rx. You will hear them and they will hear you. A decent antenna with good quality coax and get the antenna away from the house. Yes masting gets a little more difficult but it's not impossible unless you live in an apartment.
Forget RG58 coax even if it is 95%screened, you need RG8 mini at the least or better. Preferably M&P hyperflex 10 or LMR400.
IF YOU ARE NOT prepared to invest in your station then you are just playing with radios and not taking it seriously so just stick to talking with your drinking buddy down the road chatting crap and playing music. You may as well stick with your msg mount on the radiator or your dv27 on a bikky tin lid in the loft.
12W is MORE than enough to work the world.
In 1978 I did it with 4W on AM with the DV27 on the bikky tin lid stuck between the chimney pots on a three story Victorian farm house in a valley location.
Now I use a homemade 5/8~ high gain areal at about 40' AGL pushing 10W and doing the exact same thing. Worked Japan, Brazil and Argentina at the weekend, multiple stations on multiple bands INCLUDING 11 meters mid block ch36-7&8 USB.
First you talking about putting in a car/truck then you say you need a PSU 7/12/20/30 amp ..? If your Homebase buy a set of plug in walls amps Job done
Great idea but who sells them in the UK ?
NEVER EVER USE RG-58 or MINI 8U on a base station. Run RG-213. Its like driving a expensive car with bald tires or having the windows open with the heat on.
Whats your thoughts on Ultraflex ?
"Ultraflex" refers to stranded cable vs solid core coax. I use LMR 400 stranded for my beam because it needs to rotate. I use RG-213 as jumpers in my shack because I need to move thing around often.
The differences in terms of loss are minimal. Another old wives tale.
RG8mini has nearly the exact same consistencies as RG213 with the added bonus' of being more flexible and therefore not needing to drill big holes in walls.
If you're serious then use M&P hyperflex 10 or LMR400.
HOWEVER I do agree that RG58 coax is a waste of money even if it claims to be military spec 95%screened.
rg58 is rated at 800 watts at 30mhz. rg213 is 5000watts at 30mhz. another waste of $$$
Linear 11 meter running on the27, are cb radio Legal to transmit and Sales . Although they only work at 20 to 75 watt w proper ant. On a base w large ant maybe 100 watt max to have SWR anywhere close. And only transmitt on short keys. Otherwise they will burn up your radio. Al you really need is 20 to 40 watt w SWR no more than 2. Or it will distort your carrier and f___ck up everything. With 4 watt unit tuned to 1.1 to one swr is all you need and mic gain. On skipland will go further. You just can't squeeze a chicken to lay more eggs ,it will pass it off turn and bite you.
Euros are such mud ducks lmao 😂
Linear amplifiers, in the CB context, are just tools for the tools. Those who truly wish to be knowledgeable about radio will go down the proper route of study and taking the necessary examinations to become legally licenced, non-QRM causing radio amateurs.
Most will end up buying HF radios and wideband them for use on 11 meters. Many will move on to become hams.
It's not called the muppet band for nothing😆👍
Don't waste time on these junk amps. Just buy yourself a used HF ham rig, modify it if it already isn't and use it on CB. Way better performance and they run clean. Plus, you can drive a ham amp with it and get real power that doesn't wipe out the spectrum with a dirty signal.
Bang on the mark.
I do love how these videos promote illegal use of radios and linears,
'breaking the law' says the guy who shows the world he breaks the law daily using a HF set on CB..!!
pot, kettle, ??
Yes accept that however almost everyone these days are using them. Not saying its right but it is how it is.
Cry about it, hammy ham
