Take a look:RM Italy 503 Mobile Amplifier and the President McKinley make an excellent combination

[@rallypoint1]

That’s the combo I have in my mobile and I love it!!! I run mine on 5 on the RM and it’s about 350-375w. Talked skip from here in SoCal across the country, south tobTrinidad and west to New Zealand/Australia. You can’t go wrong!!!👍🏼

[@johnRfarrer]

Thanks for posting this. I have a McKinley and wondered how well one of these would work with it

[@Charlee2015]

Really enjoy these equipment match ups, with equipment

Best videos on KZbin.

I am going to buy that linear for my McKinley.

Me too! Looks like a good combo!

@@Don.E.63 I can’t wait to get mine installed. I am going to run 1.5 Watts input to the linear.

@@jerrypolverino6025 man good deal, I know what you mean, I just put up a new antenna on my base now I'm like you I want that amp, I also love the mckinley radio, you'll be set with a great system!

[@jerrypolverino6025]

@@Don.E.63Be careful using that with a base station. You would be easier to find.

@@jerrypolverino6025 Yes Jerry your right, im just running a stock radio at the moment but I will heed your advice. Thanks!

[@JoeR203]

That was my setup. I got rid of the McKinley and went back to my RCI RG-99. My 503 is the older one with the gold casing.

Thanks Rodney! Enjoy

RM Italy makes fine Amps! And these KL503, and the HD version has also a Lowpass filter in it. I use the KL503HD, and also a KL505V. Nice video!

[@rodlink6258]

Great combination. Finally understanding why my 503 HD ain't getting it done. Had my radio DK 2 watt input!!

[@Southalabamaoutdoors]

Great information as always..

[@jerrypolverino6025]

Rooster. You do a great job on your videos. Informative. I take your advice seriously. I am installing this exact combination in my mobile. I watched this video several times. What do you recommend for input power? I was not able to see the input power. Hey! That accent of yours. I’m from New Jersey. We might have trouble communicating. lol. Thanks for a terrific video.

what did you set the AM dead key at on the radio. thanks

[@pads5804]

Hi ,nice video.. Just a question,it only say's 6 watts all mode in the RM manua for this amp.Are you sure those mosfets will take 20 watts ? Thanks

[@Rooster_Radio]

@@pads5804 never had an issue

[@ehayes5217]

What did u turn the McKinley's RF output power down TO in order to drive that 503?

[@zooyawk4526]

Excellent clip, rooster. I do have a couple of questions, and those are can you drive that 503 with more than 20 watts? Let's use 30 Watts as an example. Would that be overdriving the 503? If someone is considering the 503 is it safe to drive it with 30 Watts or, would one have to move up to the 503 HD?

[@Rooster_Radio]

Personally I'd go with the HD any over 25 peak

[@Wildersport]

I would love to see that amp paired up with the new McKinley 2 FCC...

[@Rooster_Radio]

Only difference is the new McKinley has FM

[@russfield8728]

Love your videos Rooster keep emailing coming! Gonna email you soon. Cheers Russ ..Down under.

Thankyou Russ! Waving right back

[@caspian40]

I have a President Lincoln 2+ would this amp be a good choice for this radio and if so what would be the best power into the amp as to not damage it

[@clarkustoo]

I’m thinking one of these amps with a Tre Top

[@DavidReyes-1970]

What amp would you pair with a president Richard????

[@dakkadakka9189]

I have same set up am is getting good reports ssb gets good reports barefoot but with amp on reports of distortion like its over driven I turned rf power on radio down amp worked good with bonestock 980 ssb, is it possible the ssb power isnt getting turned down with the am ?

[@Catalyst-UDX-122]

What do you think of this amp for the Lincoln 2 +?

[@michaelkirkwood3316]

So I have a older connex 3300 hp would the 503 opposed to the 503 HD what would work for my radio

[@Rooster_Radio]

Youd need the HD

[@chrispierce2942]

What's the cost of the radio with a peak and tune, alignment etc with a kl 203

[@StevieB-jj9fz]

Hello Rooster i have a McKinley that pushes 28 watts, what it the best for that radio?

[@Rooster_Radio]

Depends on how big you want to go. Any low drive amp

[@hess400]

Wht does a uniden 510 do pep?

[@terryshrives8322]

I know im a little late this, what amp woud you run with the anytone 6666? I would seriously appreciate knowing.

[@Rooster_Radio]

Depends if it's stock or wound up

[@terryshrives8322]

@@Rooster_Radio stock

[@Rooster_Radio]

@@terryshrives8322 probably a 503 or 503hd. I don't even remember the power output on a stock one, because to me it doesn't make sense to have a stock radio and run an amp. Get the performance out of your radio then worry about an amp

[@jackson4861]

What did you set the a.m. dead key to on the McKinley?

[@Rooster_Radio]

No clue, but recommended deadkey on this amp is around 2.5 watts so around that give or take

Does that radio have channels in it? Like band A-F
