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

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

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

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.

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

I like it..I like it!!

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

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

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.

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

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..

Big Boy! 🇺🇲👍

Has anyone ran the RM 7505? I believe its a 4 pill, Just curious what they are doing.

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

Sold....

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

How about showing us one of these on a scope....is it splatter or is it on freq !

mine never gets hot even at 500 watts.

What size wire should you use with the 703

How do i get a hold of you roster if i dont have a cell to text on

What is the max dead key

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