AD203 Stinger amp in a Roadking CB Radio (Cobra 29)

Installed a rm italy ad203 stinger board in a roadking cb radio. This radio was severely hacked up upon arriving to my shop.

[@hydrocrab74]

4:46 LMAO The screaming...it matched that wave perfect..

[@gpalacios6850]

Thanks again Matt! Very impressive work. I’m even more excited to try the radio out now that I have seen this video.

[@TheRadioGarage]

No problem, let me know if you need anything 73s

[@TimberTramp]

60 clean in a factory looking rig is still cool!

[@027MC7]

Thanks for the video. Absolutely beautiful radio. I feel sorry for people that get stuck with subpar work. Good to see you got him straightened out. I cant seem to get my hands on a stinger board anywhere.

[@TheRadioGarage]

Yes it seems the supply of the ad203's has dried up. 73s

[@scotthansen429]

I was into the stinger board deal for a minute. You are absolutely right I've never seen anyone show one on a scope. They have some inherent problems for one lots of heat.

[@TheRadioGarage]

Thanks..I believe I am the only one showing what I show in my videos currently on KZbin. 73s

[@577buttfan]

What you expect for toy radios.

[@jamesmoore1341]

These radios just turned up are unbelievable in audio. That stinger board will make it sound hella awesome.

[@jamesmoore1341]

The new road king comes with a 520 mosfet in it

[@davescbradiorepair8195]

I agree i don't like installing the stinger boards either but i sure get alot of customers that want it. The other one i don't care much for is the RFX 75 and 85 that mounts on the back mainly because if you install it without the cooling fan kit it just won't last and even with the fan they run to hot for my liking. Great video keep up the good work.

[@stumped4262]

Lookin good after your magic. Good job Matt

[@TheRadioGarage]

Thanks..just doing my job! 73s

[@justinruth9729]

65 75 watts on a stinger bout perfect... I use 3 diff styles on my builds i use the the 1446 /2290 on copper board ..also do exsternal amps like 9530 mosfit and many other RX series boads .. but the home builds are my favorite,only thing isnwe have to remove internal speaker...to built the heatsink and copper board placement..alot different than what u see here ,but with that said i really like the over all resaults of this radio GREAT JOB!!!

[@justinruth9729]

Whatch trying to get alot out of the stingers keep them pretty ..they already can be kinda dirty..but you did great looks well ..i asure ya it was just clipped and cranked ..inwich we both know what thos causes ... Nice work clean linear and nice to see ya achive it after the growth of amplitude..good job man ... Clean always out preform splater

[@577buttfan]

I put the limiter AMC D11 on a switch for my comp radios.. sometimes its good too have that nasty wave if your running a class C hammer box and you want too win the prize. But for normal talking especially using tube amps and or AB biasing you need a really clean waveform to be efficient and have a pleasant audio tone.

[@TheRadioGarage]

Yep clean clear audio for the everyday talkers..the comp builds are a whole other story..thanks for stopping by 73

[@joekane5029]

Am I watching a harddrive video let's start trash talking 🤣🤣🤣

[@twistedfx69420]

I come across a brand new cobra 29 lx with a stinger board half installed, it's a brand new radio with a new board. Excellent receive but won't transmit when it keys down... there is no pass thru or anything reading on the watt meter with the amp power switch on or not

[@TheRadioGarage]

What does the antenna so239 look like on the inside? Sounds like something is disconnected.

[@quinsattorney]

Gosh. What I was wondering is what the FCC fines are on top of attorney fees for running that power?

[@samfogleman2337]

I had dealing with Allen Ward “RoadStar”, he had no morals. Very poor customer service.

[@ChiefMade]

Make sure you hit it twice 😂.. I’ll be shipping the Emperor this week hopefully. I’ll let you know

[@TheRadioGarage]

I knew someone would catch that 😜..ok not a problem. Thanks for watching 73s

[@567caboverbob]

I wouldn't mind scoring an Emporer, sold mine and regret it.

[@paulwright7551]

Funny As a broadcast engineer, I do not buy a 500 watt transmitter for my 500 watt station. I buy a 1000 watt transmitter, and run it at 530 wats, depending on my antenna and the 10% plus I am allowed by the FCC. NO ONE should ever buy a 100 watt amp and expect 100 watts!

[@bruceclark5627]

Then as a "BROADCAST ENGINEER",you should understand the difference in duty cycle between a BROADCAST TRANSMITER and a COMMUNICATION TRANSCEIVER. So yes,for a amplifier that's not "ON" 24/7 you should absolutely expect 100 watts out of a 100 watt amplifier.

[@RickyTricky3223]

Just out of curiosity if you don’t like the stinger what do you recommend to get more power out a Cobra CB?

[@577buttfan]

Hahahaha,the shark tooth special!!We got a shop down on 222 in Pa here that charges $50 for his peak and tune all he does is peak L14 and clip D11 terrible! These are cool radios thinking of buying a few and doing my thing!!Did you have to make a RF shield for the install or did the stinger work just dropping in? Great job brother..rock on!!! 577

[@TheRadioGarage]

Yea man, all I needed was the Jaws music playing lol..its really crazy the amount of hacked up rigs that are out there. I just feel bad for all the guys who get taken advantage of. As for the stinger install, no shield was needed. It actually played with the radio very well. Could of got a lot more wattage out of it but then the shark would have come back for a visit. Definitely give one a try! Glad your out there doing your thing, I always enjoy your vids. 👍

[@577buttfan]

@@TheRadioGarage Ten four brother!!! Yeah I'd say 90%of all the radios I see are clipped..Ive seen them put D11 in backwards same with the TR..so rediculouse..we'll keep putting these honest videos out there and we'll keep busy!! Bump bump!

What a shame, all that trouble just to end up with the power of a Stryker or a Lincoln 2+ with a fraction of the capability. No side band, no FM, no CW, and it's likely stuck on CB frequencies too. Guess the saying is true, buy once, cry once. In that regard my next purchase will be an Icon 7300 😆
