Can you put a linear on any radio or are there standards to go by so you dont blow your radio. I have a rebel radio with the high medium and low bands and a 250 linear id like to put on it just dont wanna blow my radio

it should be fine if you run your radio on low but your best bet it to take it to your local cb shop and have them matched together..

You need to make sure your SWR are low and that the dead key on the radio is set right.

To answer your question... The radio sends output signal to the linear amp and the amp *multiplies* the output... I had a high drive linear, it is able to handle more watts input than most. At minimum radio output it was 350 watt total but with the output knob on my radio turned all the way up it was over 1,000 watts of "swing watts" which is different than RMS or "true" watts of output. What will smoke a linear is too much input wattage from the radio (unless you have a high drive type) and high SWR's... Tune the antennae for low SWR's and it will last a good while...

Brent Man im not saying that this is not what your radio was doing but the knob on your radio that is variable controls the dead key not swing there for i can see where it would bring your total dead key up but not the swing,dang sure not from 350 to 1000 watts that is a big jump.What kind of amp was it,to get an amp to do 1000 watts you need a 4x2879 comp style box at the very min and then you are going to have a little trouble getting it to hit the 1k mark. |

Popcorn, Actually with a Dosy meter always attached to my radio rig I assure you that is how it works... The variable power affects swing far more than RMS watts! Now if I had tested with a Drake meter it would show much lower as a Drake is the true meter.
At the time CB was THE REDNECK INNERNET. I had a 10 tube phantom with matched Russian tubes in the house. When you get as many years in high power radios lemme know. We had shootouts and hare and hound competition every night for YEARS! I am talking 40 guys in the parking lot each night at times. Now I never Had a BIG RADIO because I didn't want to run 2 gauge battery cables and 150+ amp alternator 1 ferrad capacitor and 4 gauge cables into the cab to power 10,000+ watts like some of my buddies ran. Yes I have seen my radio light a 4 foot florescent tube and as long as hard audio was put to the mic I could keep it lit several feet away from the antennae... Side band skip and regular AM skip shooting all over the nation and Caribbean were daily occurences. Have fun with your radios... I KNOW I SURE DID!

Brent Well i have several years in radios and im not sure what kind of radio you had that the variable power would adjust the swing and not the dead key but ok then,you want to talk radios we can, Browning s-9/r2700a into a JB-12 driving a 10 tube phantom into a set of 6 element beams on 50ft of tower here in central Fl talking to CA and the mini grass was a everyday deal back then,s-10 with a Galaxy mobile hitting a 3pill driving a 8pill with double monkey made ride around antenna,also had a Browning mark III a mark4a,two Trams D201's,and about 20 or so Galaxy mobile radios,and a 2527 base along with a bunch of other stuff and then right before i got out of it i got a one tuber made that would dead key 2k on a bird and swing 4k on a bird. |

The knob does affect dead key/rms watts as well as swing... but it is a "multiplier" affect... if your low power dead key is 2-4 watts and your audio swing is, for instance 8 watts we will say doubled... then if you crank a knob to increase the dead key to 20 watts you have increased the dead key by, say, 10 times, your swing will be 80... Not exact but the exponential buildup is there.... then hit your 350 watts with 80 watts of swing and you have just gotten into a bunch of audio output. A regular linear won't handle the dead key input of more than around 5 watts before jeopardizing the transistors...
Are you familiar with a "Bucket Club" sideband bunch around central florida? 80's and 90's? I reckon it has lost some interest with the computer era....

Oh yeah... I forgot to mention... Me and Mike AKA monkee made have swilled many a brew in his Holly Hill shop... but I met him after my "play days". Your list of components really brings back memories. The on tube had about a 5-6 inch wide tube? I remember guys soaking their rims in salt water for shootouts to try to get a better ground plane affect... Who would think grown men would fight over "555555" or "888888" was the winner.... and those 6 thousand RPM's to keep the battery topped up for the max audio...  Brent |

Ok i think i know what you are talking about on the radio one of the 100 watt radios if you turn the dead key way down on those the swing back down also so when you turn it up the swing goes up to so you use one of them to hit a 4pill,ive never been a big fan of those 100 watt radios as they are just a single final radio driving a 2pill i like the dual final radio driving a 2 pill driving what ever comes next in the line up,yeah i was a member of the bucket club back in the day they kind of went south when some people found out about some stuff going on with the board members,and the one tube box had a 4-1000a tube in it and yeah it was about 5 or 6 inches across with around 5000 volts dc running across the top of that dude,it wasnt like a phantom you touch the top of a ole 10 tuber you might just get hurt really bad you touch the top of the one tuber and you where bye bye!!!

I was a member of the club. Neat bunch but many were too "square" for me... I was a bit of a wild azz and was always partying in one form or other... But I learned a ton from those guys as well as the BAM BAM bunch in sanford and deltona. Yeah i had the 2950 25 watt model.

I am not sure... that was 1993-94 when I was getting out of it... I have since consumed mass quantities of beer, wrecked 3 trucks and an suv (not drunk related), had several other full time hobbies and learned a bazillian handles on the inner-net...
I can't remember my old bucket number, I was thinkin' 36 but that was our home S-band channel so I could well be wrong. My handle was "Rocket Scientist" aka "rocket". I was a bug man by day so if we ever met by day it would be with my pest control p-up. I paid my dues to a guy off lee road in "Kingswood" subdivision and can't remember his name either. I lived in sanford and "ray", turn key, barefoot boy were a few of the regular band AM'ers I remember off hand.

Yeah bucket 1 Ron was the guy over there off of Lee rd. I was just getting into it hot and heavy about the time you where getting out of it then,and then i kind of got out of it about 01 and just play around a little bit with them now. I talked on 13 with some guys when i first got into it then they all faded away and the skip really started rolling and i stayed down on 26.925 and 915 all the time.
