Linear Amplifiers and Warranty, things to be careful of, swr issues etc, Maybe this will save you $$

[@JayP7.62]

I’m glad you made this video. First watched it a couple weeks after ordering an amp from you. I was already skeptical about the accuracy of the cheap Astatic swr/watt meter and my Anytone 6666’s and internal meter. I didn’t want to spend more money but I also didn’t want to risk blowing a new amp. So I bought a rig expert AA35. And I’m glad I did cause both the Astatic and my radios swr meter were off. Not by a whole lot but enough to cook an amp. Plus all the features and information the rig expert provides is very helpful. I like being able to see exactly what frequency has the lowest swr. If you’re going to be running a high power radio and or an amp definitely worth the money. It’s a must have.

[@cotharyus]

Good info. Thanks. I like seeing the numbers and information the way you present it instead of just people out there spouting theory about what will and won't affect SWR and signal, etc.

[@Rooster_Radio]

Thankyou sir

[@smokinjo79]

Very good explanation of how to hook things up properly. Keep up the good work Rooster!

[@Tony-rl2fr]

Thanks Rooster. Great info, I appreciate you taking the time to explain this sort of thing. We on the outside aren't privy to this key info. Thanks again!

[@nickl3872]

Same thing with high end car audio. You buy the the transistors and caps , no warranty. I paid many times in the 90s lol

[@lonnien.clifton1113]

To get the SWR down on a IMAX you can turn the tuning rings apart from each other as far as they will go

[@paulgrodkowski5839]

Wow, thanks for the insight. American ingenuity ! Over in Canada could get verbal diareah at Queens, what does colony mean?😏

[@tracystolp5357]

Thanks for the video it helps iam new in the cb

[@Tom-xp7dl]

I see this is some old video so I hoe you still monitor it. I have a President George FCC, Palomar 250 (form new-old stock), Tram 1498, 50feet of rg8x. The radio by itself will go to 1.0 ch1 and 1.0 to 1.1 on ch40. Add the (pill box) inline and the numbers go to 2.4 and 2.7. When I start talking the radio times out as the SWR hits 3.0. I have tried jumper wires in length from 6 inch, 12", 2 feet, 3 feet, 8 feet, 18 feet and 50 feet...all with similar HI SWR. What I wonder is if I give up on this radio which I ma NOT liking very much and maybe go to a real radio, a 10 meter radio tuned to be on the cb band, could that be the way to go? I am not mobile with the radio, it is being used as a base unit. I seem to need a little bit more talk power when on skip as others say the hear me but not loud enough.

[@tomaskey6844]

Dumb question; can the RigExpert aa650 zoom connect to the output of a radio that is keyed up? Never thought about it until now. I get mine Monday and was only thinking of using it for antenna tuning and cable testing. I’ll have to check the specs and read the manual. I’m not using amps.

Where have I seen that little black 2 pill amp before? 🤔 I have warranty my tube amps back in the day, ask No Pity…3CX10,000a7 replaced with new tube. I wonder if the handle rustlers who took my name gave my warranty as well🤔

[@johndyson4109]

I have a 1:1 match through most of the 11 meter band.. If you have a 1:5 or lower your absolutely fine... Not many people have a flat match on their antennas so I wouldn't sweat it if it's not above a 1:5 match.. A 1:5 match is NOT going to hurt any equipment whatsoever....

[@Rooster_Radio]

A 1:5 match is too high for most newer transistor amps. So, your spreading bad information. Call Fatboy, carl, davemade etc and ask them if you should run your transistor amp at a 1:5. For tube amps yes, it's fine Also a bird meter is the industry standard, not a "trend". So again, don't be spreading silly stuff just because you're either too cheap or can't afford one.

[@thomaswellcome5663]

Hey Rooster. I have a kl203p, I hooked it up to my pres. Mckinley. My swr on radio and on seperate meter are always 1.1 or 1.2, after I hook up amp it goes to a 3 plus. Any ideas.

[@elmoncho153]

So after tuning the antenna with the antenna analyzer hook the coax to the amp and recheck with the antenna analyzer with the other coax that run from radio to the amp?

[@bblod4896]

Manufacturer warranties are meant for defects in manufacturing, NOT customer mistakes. You blow it up, you eat the repair, it's as simple as that.

[@Rooster_Radio]

That's using your head, or thinking cap as teachers used to say

[@Rooster_Radio]

As someone who owned a 32 pill dei and 1x4 I can tell you from experience the 2879C is 20x the Transistor

[@denp54z]

My radios, quad 6 and FT 891 run on a siro 5/8 wave vertical and without the amps, use 2 , both SWR go up when using the amp(s). So without amp swr is 1:2 to 1:5 amp on set increases to 2:1 to 2:3. I've checked just the antenna and coax is 1:2 to 1:3 max. I use th Palomar 90 at 2:2 at around 100-125 watts and don't get long winded so so far so good. I took the workman out of line ,after amp, now but how can you check the amp to antenna for output power and set without a meter ?

[@mightylion9567]

I blew up my pills and transistors because of dust getting into the box 🙄. I had a 1.1 swr on a 6 pill fatboy mobile amp. Galaxy dx94hp set at 1.0 swr. My technician set the amp up first and then put the galaxy in line.

[@scotthansen429]

Good informative video

[@dobermanguy9437]

Great video and so true 👍

[@dobermanguy9437]

I had a buddy of mine who purchased an antenna and a 2 pill amp from a cb shop they set the swr and installed the whole setup for him about two weeks later the two pill a blew up even though they installed everything they would not warrantied the box to me that's total BS especially if they did the install

[@Rooster_Radio]

Still too many variables that could have caused the amplifier to blow, outside of the install. There isn't a single amp builder in the country that will warranty amplifiers or the transistors inside them, so why would the CB shop that is just a reseller/dealer?

[@TWOSU_NEWS]

So..let me ask you a question that no body likes to answers. You say 1.3 swr...is that from the antenna jack at the amp, or is that with the amp in line from the radio

[@Rooster_Radio]

Antenna to amp. The swr presented to the amplifier.

[@timmygilbert1371]

Does it matter the distance between the amp and the cb ? Will I lose power if it’s like six feet away ?

No but I recommend a 6ft coax jumper minimum

[@howardmiller4241]

@@Rooster_Radio Thank you for getting back to me , I just don’t have the room for an amp close to the radio and I’ve had ppl tell me oh the closer u are the less power u will lose. You know they don’t make trucks like they use to lol, no room for anything anymore .

Highly recommended yes

[@williambowman7244]

Yes almost all kl amps can only take 2 to 3 input the smaller the amp the more specific the input take Frome me I stocked up on the rm 3 transistors and did number exchanges at output radio level of 3 or even 4 found best keyup at 1 1/2 and swing to 4. 5 on peaks

@@fitcher-armchair-sleuth I think if it senses 60 wats of reflected power it triggers the overload, just turn off and back on to reset.

[@johndyson4109]

I think BIRD meters are way overated. It's like a trend for techs. to have BIRD meters.. I think they are a waste of time and money. Save and buy a good meter setup without slugs and all the switches on average and peak power readings. There are olenty of other meters that are just as good as a BIRD meter for half the money..A 1:5 is NOT going to cook your transistor linear. Ive had plenty of linears over the years and ran them with a 1:5 in some cases 1:7 never had one bit if trouble.. you might have troubles if you're broadcasting like a radio station in keying down for a half hour or so. But just regular talk on the radio at 1. 5 match will not hurt ANYTHING... THE BIGGEST THING IS THAT YOU HAVE TO WATCH WHAT YOU PUT INTO THE AMP AND HOW YOU DRIVE IT, NOT SO MUCH SWR that is above a 1:2 to a 1:5 match.. The biggest thing that will blow you final drivers on a linear is the power you put into it to drive it!

[@RC-Heli835]

How long do you like your jumpers between equipment rooster? Radio to amp to meter? And antenna line Ive heard multilples of 12ft, multiples of 11ft. Throw away 3 ft jumpers use 6, 9 or 12ft. Awesome articles here. www.radiomods.co.nz/coaxlength.html www.radiomods.co.nz/radiomath.html

[@Rooster_Radio]

I use 6ft. But my antenna was tuned without a full run of coax, actually used a halfwave so coax length and jumper length doesn't effect my swr. I won't run 3ft or less because seems they cause oscillating issues with opportunity

[@RC-Heli835]

@@Rooster_Radio Yea I just discovered the 3 ft jumpers don't do so well. I've been given a 1 pill 60 watt Mini-Ball amp which is my 1st amp. I have 1.2 SWR's on my base setup until throwing a 1 pill amp in the mix. Inline I have the CB, Amp, SWR meter and antenna. Which is a trucker 2000 that I have working like a dipole. SWRs after the Astatic PDC1 SWR/Meter100Watt are 2.1 on ch1 and 3.1 on ch20 and 40. My Stryker 955 SWR meter shows its normal low SWR with the amp on with a 12 foot jumper to the amp but with a 3 ft jumper it see's SWR's of almost 3 across the channels. I have an older 955 that does a little over 1/2 watt dead key on low. On hi it does 3.8 watts and peaks at 40 watts. That's testing on AM with my limited equipment.
