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

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!!!👍🏼

Really enjoy these equipment match ups, with equipment

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.

I am going to buy that linear for my McKinley.

I got my power supply from you Rooster and I’m very happy with it. I very recommend everyone to by that power supply from Rooster y’all will not be disappointed. 73s brother.

Hey Rooster it's Matt from Pittsburgh Pa..just wanted to let you know that I like your videos. Keep up the good work!

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!

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

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

Great information as always..

Great video

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

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

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

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

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?

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

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 ?

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

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

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

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

Wht does a uniden 510 do pep?

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

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

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

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