So been reading for years about amps for 11 meters and nothing ever really 100% about them and the ones building them. Have found at least two or more threads pointing out something wrong with their builds. All the big guys I have been reading about like BBI, Dave Made, Carl Built, Hopper, Fat...

Just a little surprised. Didn't think it was that hard to do but I am no tech, obviously. I understand adjusting input power. I just wanted an option to use 4 or 8 "pills" as desired. Guessing I would have to buy one of each, and not happening LOL.

Not very technical here. I was told, you can't halve an amplifiers power with a switch in a "CB" amplifier. Like an 8 "pill" with a switch to just use 4 pills or a 12 switching to 6. I never knew. Is that true?

Yes, still coming back to that myself. Going by that if I got it right, it says the lowest IMD is at 60 pep out with about 2ish pep in. If I get the 955 which when tuned does around 60 watts where I buy them, to start I could drive a 30 "pill" forever and clean as well LOL?! If I figured it...

Yeah that I do realize that as well because the ones that are showing they are doing high-power besides Carl are radio shops. The one video I saw at Bells CB was showing almost 500 with a stock radio and then he hooked up 2 2290s doing 160 and got 675 which to me is probably more close to normal...

Yes, he says they are class C amps. That's why I'm asking this if I really should be pushing more because it's class C or stick to the specs no matter what as I've also seen a couple posts where people have blown Carl's 400hds out with the 955, doing 80 Watts peaked out. That being said I'm not...

Still a little confused as I have seen similar posts and someone stating that a carl built and the like are built differently, but they didn't know how. Same as the videos testing carls 400hdhg when they put 80pep in saying its only about half of what the amp can handle. Myself, I guess I'm...

Thank you for the information.

Yes same here that's why I'm running a Galaxy Dx979 with it right now. I read in a couple places that class C amps were built differently and I don't know how so I was just curious to find out if it's just really running the 2879s incorrectly or the way they actually build the amp.

I am happy with it but the Builder and other people are saying it can be run higher. I am not everyone and I am by no means any kind of tech, hence the question I posted. I know what the transistor specs are but I don't know how they build amps. Nice attitude by the way.

Here is the video. Also I added my amplifiers video at Carl's bench in my original post, if interested .

First may I say I love my 400HDHG Amp and Carl is good people. That being said, I have read on spec sheets 1 2SC2879 transistor max in says 10 watts PEP each. Carl says on his website about the amp "400 4 hg 2879, Class C bias, fan cooled. Max amp draw 110a, install recommended with 4ga wire and...

Yes thats what i thought from reading as well. The issue I have is getting out with obstructions(trees 20ft tall all around me and another test with buildings the same height around me) when we were testing. The predator dropped an s unit on transmit and receive when i was lower than the base...

Thank you and understood. I love the Skipshooter but I also wonder and still researching if its thin winding wire compared to all the predators metal would hinder transmit power out. I run a Carl Built 400hd with a galaxy dx979. I already have learned about the receive end(antenna type/all that...

Thank you. Thats what I thought. Just double checking.

Thanks for the reply. I have the antennas I want and my set up is perfectly tuned. I was just asking as the 5ft and the predator k-1-17 are the ones I can drive around with here and want the one that would be best for distance straight talk. Again I read in a few places while researching center...

I do have a 6 and 7ft Skipshooter and a 108in whip but I can't use them while driving around here. I was asking because said in research I was reading that said center and base loads radiate different than a top load and they are better for on top of hills or flat plains for local use, hence...

Thank you for your reply. Carl Built 400HD

I had a similar post but with a different question. Antenna on Jeeps roof center, Breedlove Puck Mount, LMR400UF Coax. Out of the two, A 5ft Skipshooter or a Predator 10K K-1-17. Which one would you choose for transmit straight talk distance? If you choose to reply please tell why. Please don't...

So giving an update on this. I am not going to be hooking that antenna set up here. As I mentioned it is not my house and when I got everything together it's too obtrusive to me. And thats not even thinking of the earth ground I should do for safety which is another thing, and it's not my house...
