Magical thanks Fred, why can’t all rigs be like this. Thanks again and still waiting for the right rig to get, CT 78-40 Alan 👍
That’s a lot neater than having to crudely short the Transistor’s emitter & collector on similar radios,although it is probably doing something similar. It is also surprising how well these tiny sets cope with heat.Thanks Fred.
Frid in the shed your utube videos are awesome my friend
Love the videos Fred!
You're always thorough, actually educating, without being condescending.
Thank you Sir.
Keep it going great.
Blessings to You and yours.

Much appreciated
I'd be tempted to put a small fan on the heatsink Fred, thanks for the vid as well mate!
Love to see a simple mod, reversible too.
This is a cool modification Fred. Thanks for sharing.
Thanks Andy. Hope you and family are keeping well.
I did something very similar on the Jopix PT31 also known as CRT millennium I think. At a glance board looks similar. Cheers for the video Fred👍
Awesome mod, thanks Fred :D
Ouch a metal screwdriver darting around 👍
Great demo Fred, very interesting.
I think it should be fine to run it like that. Its clearly done by design and you would hope it is designed well enough to run at those power levels.
Looks a good little radio
Frid in the shed I learn lot from you about cbs radios my friend 😅😊😊
It might be illegal now but when the SHTF it's a life saver, everyone should be given a choice, in normal conditions, run it on low, when there is an emergency, switch it to high, its's the same responsibility as dialling 999, it's illegal to call that number for no reason, everyone has a mobile but don't call 999 for nothing, there is no training to use a mobile, it's called Responsibility
Looks like a cool little radio Fred wish I could find one of those here in the states
i just looked ( march 8 2024)
amazon even walmart has this in stock
Mate you can easily mount an arctic cooling fan on that unit no problems. Mount with a temperature sensor and away you go. Never have to worry about the radio getting hot. Modify the top cover to allow fan fitment👍👍
Thank you for that l have just ordered one
I use one on band D AM here in the states with the "mod" as a base station next to my hospital bed. My meter shows 2.75 watts on low and 6.5 watts on high. I have it running into a Procomm PT99 base antenna. It does shockingly good for what it is. Everyone says the audio is nice and clear too. I am in Oklahoma USA and have made contacts in Oklahoma, Texas, Kansas, Colorado, Tennessee, Georgia, Florida, Kentucky, South Carolina, Ohio, Pennsylvania, Mexico and Jamaica so far.
Sweet
So band "d" here in US would be the standard am cb band?? Or is it something else.
@@PBAB17that is correct. Band D is the US CB band. Channel 1 26.965MHz to channel 40 at 27.405MHz
Thank you for sharing!
Thanks Fred
Great for mobile. Easy to stow. Thanks!
Hi Fred
Don't use the Mid 8w on Am mode there is not enough headroom on radio Fred!
It distorts the Am modulation
8w car X4= 32w pep ,radio cannot do it.
Im aware of this as put other similar CB on test communication monitor can see Am waveform distort.
I would suggest use Am 4w carrier x4=16w 85-90% so that's ok Fred
Use FM
4/8/15w only
I would advise a big fan blower in 15w mode gets real hot!
Great vid Fred 👍
Kind Regards

I'm hearing good results ,and heard Simon using one Fred.
Ctcss is way to go with CB now
Interference free!
Soon to come VoIP CB gateways ctcss controlled.😉
like the radio . i think i would strap on a bigger heat sink for high power use think medium power wouldn't be bad .i have a 2meter & uhf it has a super small fan mounted in it
That rig will get hot as a pistol at the higher power level. I recommend aiming a small fan at the heatsink.
Actually, it does not. Gets only slight warm, but not hot at all.
I have just got one in the car now
Maybe get 2 S units additional output for skip at the expense of the radio. Locally, the power difference is negligible. Not sure it’s worth it. I wouldn’t want to burn it up. Nice video though. Negative: the amount of work it takes to walk thru the menu system. Worse than a Baofeng.
Good point!
D is the USA cb band I got this radio I’m not sure if I’m doing something wrong but then cb isn’t used anymore as much it use to be I didn’t make local conversation on a little Wilson antenna.if you can put this in a mobile and get some video of that if you can .
Oh wow what a breeze those mods are. Last time I did a mod on a 40ch am-fm-ssb unit in 1982, it involved switching certain pins of the PLL processor to ground to get 120 channels and substituting RF output and driver transistors for more beefy versions...
Yes its dead easy to mod. Normally you have to solder tiny pins on a pcb.
Hay Fred this seems very compact little unit. Just want to seek your advice as I know nothing about CB.
I own a mx5 and me and my bro do road trips in Europe where mobile coverage is spotty.
I no longer use the cars areal so would be nice to use it for something.
Is this unit possible to hard wire in a car and run of a areal. I’m not transmuting far like car to car over a max of a mile
Hi. Your car antenna is tuned to the FM band 88-108 MHz. UK cb radio uses 27 MHz so it wont work iam afraid. You would need a proper CB antenna. A magmount would got center on the boot lid. More on mobile Cb antennas here. th-cam.com/video/-4dbYAigpvw/w-d-xo.html
Much better off using a small linear, the heat generated from the extra power will shorten the life of the radio.
Thank you for that l have just ordered one
Yes i think a small 35w amp would be safer for the finals.
@@CB-RADIO-UKWhat finals does it use Fred ? Did you happen to look.
Hi Fred, would you be able to post something about how and where you got your 1664 ID from? I know it's not a legal requirement in the UK but I'd still like to have something semi-official to give people? Cheers m8.
Hi try this one. th-cam.com/video/tIZoYRtd-RU/w-d-xo.html
Much easier and safer to just use a small amplifier, say something like a kl35 or kl50. Keeps the actual unit legal and fully warrantied. Just use a very good quality patch lead between the radio and the amplifier to keep losses to an absolute minimum. Make the patch lead longer if you're putting the unit into a mobile, that way it can be hidden out of sight and use an inline power switch to the amplifier.
Would be cool to see how that little power meter performs at the far end of a length of coax to simulate losses at the antenna base.
🇬🇧👍😎👍🇬🇧
i have yet to fire mine up.
but found a neat place on my dash this little guy fits into.
now awaiting daylight so i can hook up the coax and power. not sure if a chassis ground should be installed. as everything is plastic these days.
is the dc power ground ok for this radio
source and ground directly to and from the battery.
unit is isolated.
TBH ive not wired a mobile rig for a long time but i always used a ground point as an earth. The radio does not pull a very high current.
But does the dummy load prevent the radio from damage if it’s connected to that rather than an antenna?
You would be fine with the antenna but power would depend on the SWR. The dummy load has a perfect 1-1 SWR and is a 50 ohm impedance so no power is lost.
@@CB-RADIO-UK ohh that’s great to know!
Any idea if the other radioditty models have the same mod available?
Not the same iam afraid and no where near as easy. The little CB-27 does have a high power mod but requires soldering skill.
CRT ONE V has the same L-4W M-8W H-18W power modes and (A to L + UK bands.)
@@subsubl is there a video for this mod?
@@Freedom-projects You will see in the middle of the pcb the six dots inside an oblong(elongated white square). For 10-12m mode join the top two on left hand side on the top row of dots. Higher power join the bottom left two dots together. Don’t join top to bottom! Only horizontally.
Mine was Dead on arrival I sent it back for a replacement. This was my first Radioddity, as im a Cobra guy. See what happens on the replacement.
Sorry to hear that. Guess it happens. Better luck with the replacement.
@@CB-RADIO-UK exactly we'll see what happens.
Don't waste your money on buying that radio it don't have upper and lower sideband and it don't have lower channels in it either and it don't have a lot of power like a galaxy Stryker or the rci radios I won't buy that radio Fred in the shed you got ripped off dude 73s
Your going to have to pay double the money for a SSB radio. This is a good mobile solution.
@@CB-RADIO-UK not it's not sometimes you have to bite the bullet
@@CB-RADIO-UK and lot of people like upper and lower sideband and lower channels that away the can talk so people don't Walk all over them
This is a great little radio for having a mobile CB. It is easy to use, requires no license, and is discrete in the car.
The radios you mention are very capable and powerful radios, but they are in a different class, serving a different purpose.
@@mr.l3785 I use my rci 2950dx mobile as a base unit my rci 2950 Dx mobile is hooked up to a power supply and the radio has the cb band and the 10 meter band I'm also a amateur radio operator

Sorry about that but its just the way TH-cam is run these days.
It’s not an airport, you don’t need to announce your departure
@@RingwayManchester😂😂😂 Brilliant reply Lewis and even more so from yourself being named after an Airport 😂😂👍👍
Mind that door it bites.
A frequency readout would have been nice with all the different bands. Who knows what frequency you are on in N or F band.
