Your radio room is super nice bro, I been just getting into radios lately and wanna setup a base station setup. Got a cb in semi (stryker 655) barefoot and a uniden 880 with rm italy 203 in my chevy malibu so far!

Thanks Steve, the best experience I’ve had is setting up a base station and getting comfortable inside a dwelling. Too many years it was all mobile Ops for me, now I just run a Stryker 655 bear foot in the mobile, simple comms set up. But all my effort will be in the base station set up. 73

Man, I'm glad you posted this video. I don't know how I missed pt 1 but I went back and watched it, too. I have been looking for some informative videos on this amp and you delivered! I have been considering buying one of these but haven't seen any info or any real world videos on this amp in action. As far as price, the amps I've seen for sale run ALOT cheaper than most amp builder's prices and the 703 seems to be much cleaner, build wise and signal wise. If you don't mind me asking, where did you buy yours from?

It was calibrated with a bird meter, the adjustment below zero is to compensate the fake watts that the peak kit reads on the MFJ.☑️ Nice try though little guy lmao, come back when you get a tech bench and actually know how to operate test equipment.🤣

If you had a choice between this amp vs a new Texas Star 500V quality/talking wise what would be your thoughts?
@GroundControl204 10 ай бұрын
To be honest with you, I would still choose the RM 703. They don’t get as hot as the TS500 and believe it or not the 703 is a lot cleaner on a spectrum analyzer as well.

Cool. I know there’s a thousand different options these days. I only use my stuff occasionally. I always herd Texas Star was some of the better ones but now with all the fake transistors I’ve been reading about I dunno. Then the Horror stories you hear about mosfets. Seems it’s about up to the user. Looks like you have a lot of nice equipment so wanted to get your opinion. Thanks man

Thanks for the great review video, I just ordered this unit from RMS radio supply out of North Carolina looks like they have a really good price at the moment. Just hope it shows up. I have a local selling his very good shape Texas Star DX 500, They want $500 for it said they are original owners since 1994. Decided to go with a new RM Italy instead. I still might try to trade him one of my high power ranger radios just to get that Texas Star though. 🎙73's

Great video Ground Control. I know you said your 959 keys at 6 watt is it swinging to at least 30 watt? My manual says to obtain peak performance use 30 watts and not more then 35 my bearcat keys at 4 and swings to 15 watt so far getting 250 peak looks like I need to step it up haha was thinking of running down my Stryker 955 what do you think?
@GroundControl204 2 жыл бұрын
No more than 40 watts peak of drive before my amp was modded, after my mods I now drive it with 80 watts peak from the radio. The amp now does about 800 peak instead of 500. 73
