Please consider turning your video sideways on your phone (I assume you are using a phone video recorder) it doubles the viewing area! Holding it up and down is hard to watch. Thank you! :) Great test by the way, and not far from what most people are seeing on this amp on the AM side.
On your SSB video, you stated you got 350'ish out of it for AM but barely hitting 200w here, did you change anything from the time you made this video to the SSB video to make it do 350am? Thanks!
I've a KL703 and over 175w AM it overloads neighbor tv audio amp. Yes c.b. still can cause issues. Good news is I am good to about 300 W peak on ssb without complaint.
Wouldn't do that hit if the radio was tuned properly. Swing kits and cutting out limiters, spreading coils and bolting the finals causes all of that garbage.
Mine is exactly the same. Pretty disappointing really I can actually get 200W out of mine dead key on setting 4 but only if I pour 10W up its ass. I’m going to try having a measure of supply voltage right at the output of the three input fuses.
lower your drive, its compressing at the higher numbers with less input padding. it will damage the reciever and as your audio would be distorted. For 6 a dead key of 2w is better.
miamicb Not correct. It’s a linear amplifier! More power in = more power out and vice versa. It is not an audio amplifier. Looking at the circuit it shares the obvious similarities but being an rf amp it has its small differences. It is rated for a maximum of 6W in and comes with a warning regarding exceeding that. I can only get maximum power out by driving 10W in, turning that input down from 10W has a corresponding decrease in output power as one would expect.
@@specialmousenz I concur with miamicb. What you have there is the output transistors saturated and clipping, cutting power. This amp is not known for stellar pep anyway. Try it again cutting back dead key until oversaturated condition on high stops.
It’s seems like there not all the same ! My 503 sorta acts like yours but my brothers act more like the other video on TH-cam to where it’s in the 270 range
Mike Daniels I recall on mine setting 1 dead key 30 watt and peak at 125 watt, setting 2 dead key 100 watt and swing to 275 watt all approximate numbers there all setting after that didn’t change much, and I recall driving it with a 3 watt dead key.
Turn the Watts up on a 2000 all right but first to the research on that app find out what it can handle the Watts that are coming out of that radio some of them are two some of them are four five hell man I seen people push 12 Watts out of it and not hurt nothing and get a little bit more watts coming out of that amplifier than what you're getting out now something ain't right
Obviously this guy does not know Cb Amplifiers skews me 11 m Amplifiers it’s a 2:45 hundred watts which would be 50to75 W of dead key and then you let it swing from that point on dead key in it at 150 or 120 W is just going to blow it up it’s a quarter of what it puts out which is 300
Actually, these work better with about 2-3 watt dead key and a decent 20-30 watt swing. In addition, you want to run about 14.5 - 14.8 volts to really see it's potential.
Beware this is not made for CB it is illegal to use this amp on CB @ Regulations and part 95 rules states you must follow the required band plan for HF this is 28300 - 29200 and you must have a FCC Licences of a Tech Genreal or Extra Class licences Fines can range up to 10K or as much as 20K per day that you are found using this off the required bands .. Just a friendly warning Beware unless you can pay the fine you can check with the FCC for more information...KG5CUO
The FCC doesn't give a shit about 27mhz or VHF UHF. I've been a Ham a long ass time. The reason they have the rules for CB is because of truck stop cb hack shops causing harmonics. If the amplifiers were AB biased and people weren't "PEAKING AND TUNING their CB radios, they would run relatively clean and not cause harmful harmonics.

Dude...you really need to get a life instead of copy / pasting this in every amp video. Worry about KG5CUO. These grown men and women can take care of themselves.

Try using a matcher for optimum swr each time you flick the switch you will see a huge difference
On your SSB video, you stated you got 350'ish out of it for AM but barely hitting 200w here, did you change anything from the time you made this video to the SSB video to make it do 350am? Thanks!
So how did you get 350w when you didn't think it was doing what it should?
The dead key is too high !! Turn it down to 1-2 watts and let it swing!
Could you do video testing it on ssb for power output ?
I think a lot of people would be interested like myself.
Posted! th-cam.com/video/OLl1b-49B_s/w-d-xo.html
Might need more DC amperage to get more than 160w out.
Seems to me if you are getting lower out watts on higher power you have a bad amp or too much dead key/low modulation?
I've a KL703 and over 175w AM it overloads neighbor tv audio amp. Yes c.b. still can cause issues. Good news is I am good to about 300 W peak on ssb without complaint.
Yeah, I made the same mistake running 200 watts AM in my hoa neighborhood.

Have that same 700 meter and I have to calibrate mine every time I make a power adjustment

@@robertdixon6536 yep, needs lower DK. A proper pep reading meters needed as well.

Lower your deadkey to 1 watt
Looks like your amp won't go over 170w or so. Amp probably needs more current than your power supply is able to deliver.
How’s your kL 503 holding up
William Daniels what was your numbers again will , didn’t we read that not all are the same somewhere
Mike Daniels I recall on mine setting 1 dead key 30 watt and peak at 125 watt, setting 2 dead key 100 watt and swing to 275 watt all approximate numbers there all setting after that didn’t change much, and I recall driving it with a 3 watt dead key.
How many amp power supply you using.?
Rooster tested the same amp with a thirty watt swing. His peaked at 400 watt sideband draining around 21 amps.
It's got to be 30 amp power supply.
SSB PLEASE.
Lower your deadkey to 1 watt,mine peaks at 320 watts
Turn the Watts up on a 2000 all right but first to the research on that app find out what it can handle the Watts that are coming out of that radio some of them are two some of them are four five hell man I seen people push 12 Watts out of it and not hurt nothing and get a little bit more watts coming out of that amplifier than what you're getting out now something ain't right
Just something ain't right
Peak reading meters good for nothing.

Dude say audio audio not modulation really
Too low your load watts, try with 5 dead key
Actually, these work better with about 2-3 watt dead key and a decent 20-30 watt swing. In addition, you want to run about 14.5 - 14.8 volts to really see it's potential.
Junk
wrong testing equipment
Your meter isn't a true peak meter.
my neighbor has 3 rabbits
What a joke. Less than 200.... best to get a Texas Star or other much better boxes.
