My rear 6lq 6s don't light up what do you think's wrong with it

Won't the wind knock it over?

I just bought a new one off Amazon and the board is different than what you show in the video, I can't see a D203 diode anywhere and the only one underneath that metal is D201, do you know if the D201 will do the same as removing D203?

The Amp is on top of the radio in the beginning now the Amp is on the bottom of the radio 🤔🤔🤔

Do not do this crap...make u sound like shit

This is the best video for this amp I have seen on yt. Would this be the same tuning sequence for the newer brown face Maverick dual power amp that came just after the grey? Also did you set the swr calibrate while the amp was keyed up? Again, thanks for sharing all this great info' about these fine amplifiers! 73 160 MI. ✌

I would have just used the ANL switch on the front of the radio. Just wire the ANL so its always on. ( I never turn it off anyway lol ) Then use the switch in series with one leg of the diode to have the best of both worlds. Can't hear me, flips switch... Can You Hear Me NOW !!!lol

Great video. Im subscribed. Im in the market for a new base station ground plane. Im on the fence between this Maco V58, the new Sirio Monsoon, a Solarcon MaxOptimizer or for one of the 3 big boys, i.e. Excaliber, Shockwave or Colossal 10k. Can you give me your thoughts? Id like to make a video of my upgrade one day. Just a big decision you know? Lol.

would not buy a Radio without sideband.

Could I possibly get a copy of the manual

Decrease Power Increase deviation Equals slightly garbled voice over lower power. So why do it?? Also, the KL203P will happily handle 6 to 8 watts on am and fm, and 10 to 15 watts PEP on ssb. As a guide the output from the 203p is average of 10x the input.

I have one of these but is says thunderbird 350?(looks like homemade stickers) but looks just like this 250 u have here in video showed n learned a lot I am most grateful some more information on this particular model (serial no. DPM-51077) I turned the dials or knobs wen I ran it just a lil bit idk what I was doing and if my meters waz correct was doing about 900watts most I seen was 1200 so I cruise on 900 b gladly to share pictures and any video of this box if I can learn a little more again thank you for this video you done really showed me how to tune the box 💯

Back in the cb days I had one worked great till I accidentally had to many beers one night and drove about 150 watts into her. She wasn’t happy about that at all.

I dont get it: this is the second (US)video about the Kl203p amp Saying only 2 watt The specs says Max 10 Watt input. Being causious I set my dead key/ Radio to 8 to 8,5 watts Wich gives me dependant at frequency between 80 and 110 watts output! It doesnt blow up! This is on Fm . On AM I the variable output of the radio drops , so I also turn it a bit up till 8 watts

How's the plan?

Do you have any amplifiers for sale now?

Any way I could get a copy of that manual?

I don't recommend more than 1 watt imput with this amp. 2 watts or more will cause it to splatter, and probably also cause a squeal in a cheap radio. I have a KL203P connected to a President McKinley radio, with the power turned down to 1 watt, it seems to work fine, no squeal, and will not overdrive the amp and burn it out. This amp uses MOSFETS, and they are pretty fragile.

Why would you say it's ok to use a metal screwdriver ??

I just acquired one of these. I really don’t know much about it. All the tubes light up. That’s about all I know. Any chance you could provide any docs on this thing?

My swr goes from a 1/1 to a 2/1 during rain snow or ice. Measurements are good, coax seal on coax.. drip loop on wire and coax itself, the swr is great in good weather. Horrible in rain. It blew up my 700$ carl built amplifier.. I didn't know it started raining, shew. I talk all over the world. But this high swr in rain is killing me.

I still have a hard time understanding why the copper wire (center lead for the coax) is connected to ground. Would it short out the output section of the radio or amplifier?

on the very top how far dose it gos in

It’s recommended to insert an extra inline fuse on the amp if you are connecting to a cigarette connection!

easy assembly i did mine in about 25 min

Do I need to tune my radio before I use one of these

Removing the AMC limiter destroys the audio quality. Don't do this.

✋I do not like the Maco V-58 Antenna`s, its never perfect 1.1, even on the Maco `s own UA-cam he had a hard time tuning the contraption (even not hitting 1.1) I asked the manufacturer for a solution and they suggested using a Matchbox to get the antenna 1.1. Are you completely serious Maco! A freaking Matchbox!! Also after a view mild storms the Antenna makes al kind of crackling notices. 👉I suggest not to buy this misproduction.👈

First thing I did was replaced the hardware with stainless steel

You would think that the connecting wire would be thicker for 5000 watts. I'll have to run it through the Watt's Law calculator. Current equals the square root of power divided by resistance, so the wire needs to be able to handle 10 amps.

If it was me I would set the radio dead key down to about 2 1/2 Watts and you will probably get a little louder modulation. And most likely you will probably get a better average forward swing.

IIRC, the 6AQ5 is the tube that operates the keying circuit. From the manual, that's a post-1974 amp because that's when the radio power limits were changed from 5 watts input on AM/15 watts input PEP on SSB to the current 4 watts output on AM/12 watts output on SSB. These were quite popular before 1972 because the most popular antennas could handle the power output. The CLR2 was rated for 300 watts and the Super Magnum was rated for 350 watts. If you wanted to run a Phantom, Skipper 300, or bigger you needed a beam, Mosley Devant, or the Astro Plane. That changed when the Penetrator and Starduster were introduced in 1972.

Can u make a video on the older bored

The output of these amps is full of harmonics, which means that your transmitting on many frequencies all at the same time, not what you want to do, particularly if you're doing something that is illegal. Consider using a low pass filter between the amp and the your antenna, this will remove the harmonics.

Looks like removing the diode causes overmodulation and distortion. Audio is best at about 60-70% modulation and no higher. Otherwise distortion reigns and your signal splatters over 3 channels. But whatever. It’s just CB, right?

If you got a HAM license you could use 1.5 KW legally.

Hi Mr. Steve! this exact video was such a great guide to using both units and I had great luck with the 505xl on its own, but when I added the KL203P, I get a gnarly squeal on transmit. I have an SWR of 1:1.05, and a short coax jumper from radio to amp. they're both powered off of a 30A 12V circuit in my car and I have it set at exactly 2W radio output as suggested. when I bypass the amp, I don't get a squeal and the signal is super clean. when the amp is on however, I can almost hear the squeal from the radio itself. I've read some solutions like an RF choke on the power leads or mic cord but was wondering if you had any thoughts. Thank you in advance!

Fm doesn't works?

what does the waveform look like on a scope?

Does this apply to the 520? Thanks

Junk radio 😂😂😂😂

lmao SMH guys dont do any of this ! just buy a loud power mic

What is the outer diameter of the top rail fence post?

Pads ripped right off, no going back😑

good presentation how to set up and tune this antenna. Maco's instructions and schematics are very poorly written all their antennas. Thanks.

Can I ask the weight of this antenna?

If you need a CB to keep up with traffic on the road this ones fine with a removable antenna but I wouldn't have that for normal communications . At least a Cobra 29 LTD classic is better than that back pocket radio lol

The uniden pro 510 has a Anl

THANKS FOR THE GREAT VIDEO !!!!!!!!!!!!!!!!!!!!!!!!!

Hi there Mr. Steve and to all o this channel. First, I just want say thanks for making this video. ever since the first CB radio I had an opportunity to turn listen to and talking on, I have wondered what all of the adjustable parts do. Like those adjustable coils and adjustable resistors. When I talked on the air some would say that if you open the radio and adjust those things you can increase the talk power - like output power and modulation as you show here. I am also interested in how to increase the receive sensitivity so the CB can hear weaker signals so that it is a 2 way street - further talking and further listening! I have a Uniden Pro 520 XL and I find that by opening the covers and adjusting the coils near the back of the radio with just my finger, no tuning tool required, I can increase the output transmitted power up to about 20 watts as I read on am Astatic power meter.
