RM Italy KL703 Test Video for Customer

[@125southernnh2]

So that one is about twice the juice the 503 outputs. Makes sense since they doubled the MOSFETS. I just bought one!

[@johnnyphillips9735]

Hey mr rooster nice amp hillbilly in the bam waving your way

[@robertmeyer4744]

I got one for a friend. works great. Now on FM you can turn up drive to 4 watt or so but watch SWR and key down time. I had a few KL203P with 4 fet's come in blown .keep drive down and watch temp and SWR . 73''s

[@jacoblloyd8851]

What's dead key should I run into this?

[@robertmeyer4744]

@@jacoblloyd8851 on AM about 1 watt with swing 12 watts PEP around.

[@Dallas-Rife-UDX-347-Tennessee]

Not bad at all , actually impressive 👍 And they keep getting better Good video Rooster

[@Trump985]

Power is one thing but how clean is it? I’m more interested seeing these amps tested on a spectrum analyzer.

[@jacoblloyd8851]

What is the max dead key

[@jeremysmith8020]

5 w

[@jeremysmith8020]

2 swinging 30. Is perfect in my opinion. I run one

[@kevinmccool3719]

Rooster, how much do you sell this unit for? I'm hoping they are still available in a few months from now as I plan on maybe getting possibly 2 of them. One for the house and one for my truck with dual batteries and hi output alternator.

[@scottcarrier1121]

Do you do repair work on the 503 HD's? I believe it needs Mofsets replaced. I might have got over driven but I'm not sure. Any which way I set it up...it won't get over 175 watts...Thx

[@redk9102]

Noob question.. Is this amp designed for CB radio or Amateur radio..? I was thinking that CB had a limit of 12 watts PEP ssb..

[@RT038]

The switch am fm then ssb can you run it without the relay if your on ssb but have it switched to am will it damage it

[@EdzashedFudwinkle]

Rm's are made in Italy, hence the Fm added with the Am, and psu required is 60amp

[@EdzashedFudwinkle]

Also 20/25w is plenty, no need to lax them out at 35w, imo 30w is too much. Also an SWR of 1.5 or lower is required, or the amplifier will die a sad death.

[@Rooster_Radio]

@@EdzashedFudwinkle 25 watts won't produce 500 watts PEP which is what they're rated at

[@EdzashedFudwinkle]

@@Rooster_Radio I've been looking again today at them with a 75a psu. Running them at 13.8v (Uk) and not 14.5v makes a difference does it not? You know more than me brother, I just use Fm/Ssb oppose to Am, appreciate the reply though 👍

[@robbierussell9536]

I like it..I like it!!

[@jasonmiller9495]

I just bought the kl 300 p . Man it’s a good amp but the pre amp sucks because if the amp is on the pre amp stays on. You just get too much white noise . I constantly have 9 lbs of noise the whole time I have the amp on. I might buy this 703 but it’s pretty big size wise for my Freightliner. I want a Texas Star but finding one converted for 11 meters seems impossible

[@Rooster_Radio]

Go for the 503hd

[@jasonmiller9495]

@@Rooster_Radio thanks I was thinking the 503. I might pick one up after Xmas . I think the Grant xl would be screaming with that next to it and the pre amp can be shut off

[@Galaxy2517]

Sold....

[@rubenverandi]

donde se puede comprar en EEUU ? 73

[@patriciaenochs3094]

What size wire should you use with the 703

[@125southernnh2]

I think they recommend 8ga.

[@DeltaXray444]

I use 8 awg on mine with a 30 watt input on fm using my superstar 6900n, 8awg will carry around 180 amps so is plenty to carry the voltage from the psu.. the amp spins out a straight 400 watts on a fifty amp supply, been running it for over a year with no problems and im a rachet jaw.

[@charlessalard4636]

What's the difference between a 503 and a 503 HD?

[@Rooster_Radio]

503 is recommended to only take 25 watts peak. 503 hd will take 35/40

[@zukispur5493]

@@Rooster_Radio 25 watts peak? I never put more than 4 into mine

[@Rooster_Radio]

@@zukispur5493 you're either referring to deadkey/carrier or average power because there isnt a radio made today that only "swings" 4 watts peak.

[@zukispur5493]

[@kingduckford]

Been waiting for months for these to make a return on the market. The whole amperage thing has been my big concern, especially after watching a customer review where his PSU peaked at 55 amps 13.8v driving it to 500 watts output. I fear this might be too much for my radio mobile setup that uses a separate marine deep cycle not connected to the car's battery (expedient for field use outside a vehicle, and not putting the car's battery at risk of drain), and the CB home unit I try to reach with my mobile for local contact is currently set up with a 25/30 amp switcher, which sure ain't enough. I know my monster Astron 57/70M won't break a sweat. But I fear this might even let the smoke out of my cheapo beater Pyramid 52KX. Might have to move some PSU's around, or buy another one.... Thanks for the video.
