3000 Watt CB Linear Amplifier
This home brew amp put out 3KW the first time it was fired up. After tuning and a few mods it eventually did 5KW on the 11 meter CB band. It was created for mobile use! The rig? A 1963 Ford pickup with a small block chevy under the hood, a Dodge rear axle and a datsun 4Cyl engine in the bed to run the 12KW Genset that powered the AMP. The only thing in the cab was a basic Cobra 40 Channel CB. There was a remote start for the 4Cyl genny and the amp could be online within a minute or so. The driver amp was a solid state 500 Watt brick if I recall correctly. The output tube was an Eimac 3CX5000. Video was shot May 19th 1989.

? I’m a ham of 30+ Years and have never broken the power rules, In fact” 20 to 50 watts is all I need to work the entire world.
September 29th, 2012 at 7:43 amIf you think? hams don’t break the 1500 watt PEP rule- you are sadly mistaken. Happens every day.
Stick that in your ham hock- Hypocrite.

September 29th, 2012 at 9:31 amShining your flashlight into the air doesn’t interfere with other flashlight users tens or hundreds of miles away. Interference administration is the big reason for needing a license. If everybody just did what they damn well pleased, the RF portion of the electromagnetic spectrum would be useless. The FCC puts radio users in their little? chunk of the spectrum for a reason, and with limits. If y our unhappy with the FCC rules, your welcome to move to another country that is a bit relaxed.
September 29th, 2012 at 10:03 amChoppergirl Part 1 says I can use all the? power I want, and I am polite about it and not step on other people’s signal.
September 29th, 2012 at 10:09 amAir waves are free for everybody to use. I don’t need a licence to shine a flashlight into the air at the stars at night, and I don’t need no licence to transmit a radio signal in the ether. Both are exactly the same thing, electromagnetic radiation, just on different? frequencies. It never ceases to amaze me how ready and willing humans are to seek some authority to fear and obey, even when they’ve never even met them in their life. You are your own authority.
September 29th, 2012 at 10:50 am(cont) of 11 meter RF can be dangerous not just for the operator, but also for people? around them. Imagine if you are sitting in your care and some kid comes up and grabs your antenna or gets near it and ends up with RF burns on their hands. Or you interfer with a emergency service radio system and prevent paramedics from getting to the proper location. If you run CBs, do so legally. If you want to run more power take the amateur radio test and get on HF with us, we’d welcome you.
September 29th, 2012 at 11:11 amWhen you start getting close to the VHF bands amateur radio operators are required to do an enviromental survey. For 10 meters it is required if we run more than 500 watts. We have to dertermine RF exposure around the antenna and determine the safe distances for operation. When we get into the higher bands like 2 meters we have to do the survey if we run? more that 50 watts, because RF exposure (especially with direction antennas) can cause health issues. Being in a car with 3000 watts (cont)
September 29th, 2012 at 11:44 am(Cont) required to carry on a QSO with the other operator. I found that having a good solid antenna (I use an inverted L with about 25 ground radials) makes a world of difference along with good feedline. 100? Watts is generally more than enough power to carry on a QSO is conditions are good. That being said; CB is still supposed to be a local radio service for communications up to 10 miles. They allow the 150 miles just incase of propagation being uncontrollable by the operator.
September 29th, 2012 at 11:44 amThat is true, but it doesn’t change? the fact that the Citizens Band Radio Service is limited to on 5 Watts AM and 12 Watts SSB. The FCC doesn’t care how clean the signal is, you are still not supposed to talk to anyone beyond 150 miles. I also used to CB before I got my amateur radio license (Call W8MLD). I didn’t see any reason to run more on CB than I was legally allowed. As an amateur now I barely ever turn on my amp, because FCC Part 97 says we should use only the max power (Cont)
September 29th, 2012 at 12:22 pmBelly aching hams… Blah, blah, blah.. ?
September 29th, 2012 at 12:47 pmYou guys are ALL a bunch of amature “mud ducks” as we used to say. I have talked around the world on 5, yes 5 watts. I have QSL cards from 23 different countries, all worked with a HOME MADE dipole antenna. I have mabye 300 bucks in my? rig, 100 of that was for good co ax. Study up on your antenna design, and you’ll see less is more. N3KSZ
September 29th, 2012 at 1:08 pmi do agree hams also run illegal power but they are more responsible about their emission they make sure the signal is at? least clean. CB guys don’t give a shit how many frequencies they screw up.
September 29th, 2012 at 1:24 pmWhats so funny mike is i know tons of cbrs who r hams also, and dont think for one second all hams run legal power, i know better and have seen them running 5kw or more.i know one ham running 7 kw now so dont think hams r better? then cbrs do your home work. have you read the reports? on QST about hams being busted for interfearing with police and fire services? or get big fines for running over the power limit? we r all human and do things we shouldnt.its a hobby so dont loose any sleep over it

September 29th, 2012 at 2:18 pmWell ill agree on a few points you made, yes some run dirty signals, but nowhere neer what you may think. many cbrs i know run ham? amps.and many run nice clean audio, so dont pool all cbrs in one box. thats what makes many hams fools becasue they think (all) cbrs run trashy sounding radios. I happen to be both ham & cber. i run a clean station that has no more RF going out than your ham eqt. Did you know many cbrs use ham rigs to transmit? so why must you put “all” cbers in the same box?
September 29th, 2012 at 3:07 pmYep run the thing to max? power with the top off the P.A. stage, no shielding no brains no ticket brain cancer dont hurt much, well not for long anyhow. So stick you tong in there good buddy.
September 29th, 2012 at 4:04 pmYou polish a turd.? , you still have a turd .
September 29th, 2012 at 4:57 pmWoulda coulda shoulda?
September 29th, 2012 at 5:45 pmhow do you amplify? a linear dc circuit signal?
September 29th, 2012 at 6:41 pmCopy that… no substitute for having an antenna at 8 or 9,000? ft. elevation with 100 watts.
September 29th, 2012 at 6:44 pmtry hitting 10kw of RF, then the RF exposure will rid the world of? you faster
September 29th, 2012 at 7:12 pmtoo much money to invest in a box that? is limited, puts out a dirty signal, sounds horrible on ssb. would not last the next 2 years without repair. confine to just one segment of the spectrum.
September 29th, 2012 at 7:52 pmbut i guess to say just a few words 300 miles away is perfect,,
A 3kW power? amp on a CB is a waste of electricity and time and money. To those that say Oh the FCC doesn’t monitor CB much anymore, you’re right. However, the Amateur radio operators do and report violators to the FCC. A few radio direction finding techniques and a few hours listening to unauthorized traffic “bleeding” over to licensed bands and you will get caught. Just read some of the FCC letters sent out to persons operating illegal CBs and other equipment causing harmful interference.
September 29th, 2012 at 8:23 pmThe biggest of amps won’t help your signal if we’re having bad propagation
September 29th, 2012 at 9:07 pmand most of the ‘magic’ is in the? antenna not the power amp. LOL
be careful not to KILL yourself or someone else with that booger..
-sincere remark-
Did you build it? yourself??
September 29th, 2012 at 9:21 pmSo? clean!!!
September 29th, 2012 at 9:59 pmI like that deep tone vtec. Cracks? pretty hard too.
September 29th, 2012 at 10:47 pmNice car dude !?
September 29th, 2012 at 11:42 pmI got lots of questions for ya I’m in saskatchewan? canada add me on facebook I got a vtec mini aswell bill soucess
September 29th, 2012 at 11:46 pmMan she goes !! Love it. Check out my channel for my classic Works cooper ;-)?
September 30th, 2012 at 12:40 amcheck out minimania dotcom they have all of the kits to start off with to do the swap and all. It took over 8 years to get this? baby to where it is now but it was worth every $ and second. I am not selling it currently but would be willing to take 35K for it if anyone was looking.
September 30th, 2012 at 1:18 amwelldeon for taking time to state all the parts you put in, if i want to do something similar where do i? start from, and if you intended to sell this beast how much would it go for?
September 30th, 2012 at 1:29 amFor sure my friend look through my videos I have a qtr mile run on here going back to the track when it heats up more because at night when it cooled down the? LSD was throwin me all over
September 30th, 2012 at 1:56 amNice car man.? Any 1/4 mile times?
September 30th, 2012 at 2:51 amhaha yea thanks man I? love that sound!
September 30th, 2012 at 3:35 amVtec cracked? hella hard!
September 30th, 2012 at 4:07 amI could have sworn i was watching pauly shores drive. ?
September 30th, 2012 at 4:51 amOkay,? your interior is gorgeous. Where did you get your dash rail covers?
September 30th, 2012 at 5:39 amStill have it? and will most likely be able to keep it now =)
September 30th, 2012 at 6:24 amI can’t believe you are selling this beauty of yours. ?
September 30th, 2012 at 6:38 amIndeed I? do and yea I changed the final drive from the high 4s to 4.05 =)
September 30th, 2012 at 7:16 amGorgeous car, do you still have it? I imagine if I were to do this swap I? would take a 5th gear cog from a taller geared transmission to have a more enjoyable drive at highway speeds. Pretty sure 5th gear from an LS Integra transmission fits right in with no troubles.
September 30th, 2012 at 7:32 amleast he’s? sat on the correct side of the wonderful sounding mini …cant imagine driving a left hand drive one :S
September 30th, 2012 at 8:00 ami was thinking the same…the mini isnt full of roll cage,witch is good ,people in their saxo’s laughing at the little? mini but left speechless and shocked when it takes off ! haa
September 30th, 2012 at 8:57 amnice? vtec sound !!
September 30th, 2012 at 9:52 amis it hard shifting with your left? hand instead of your right?
September 30th, 2012 at 9:58 amGorgeous interior, I like how you’ve? upgraded the performance massively but still left the classic charm of the Mini. Is what I’d do if I were to ever convert mine.
