Building the Mercury IIIS Kit | Assembling the Mercury IIIS Amplifier | My Building Process and Log

[@lpollis]

Thanks Capt Darren for an enlightening presentation. I am a "Born Again" ham, once licensed as WB4UPA, now KI5UXC, licensed on April 15th! My Mercury IIIS is on the list! I will be driving it with my IC-7610. Can't wait. Your video shows me the process that I hope to follow. Lp KI5UXC Plano, Texas

Excellent description sir. De VU2STO. This will inspire others to DIY amp

[@bigskyblessing]

Awesome video we are watching from Alaska

[@rtrjmk5]

Thanks so much. This will be a big help when I get my amp kit

[@DarrenN4VFR]

@rtrjmk5 Your welcome! I enjoyed making the video. It took me 2 days because of videoing the process and when my little girl came home from summer camp, I spent the day with her and took her to horse back riding training. 73's and good luck on your M3S.

Hello Capt Darren. I would like to know the wire connection for 240VAC operation. I see on the amp connector L, N, and Gnd. How do I hook up the plug for 240 VAC? I have a 40 amp service in the shack with Two Hots wires, one Neutral, and one Ground. So how do I connect a 4 wires service to a 3 wire device? Thank you!

[@DarrenN4VFR]

If you have already have your shacked wired for 240 VAC, the Mercury IIIS amp will sense the voltage. It's auto sensing whether you use 120VAC or 240VAC. At timestamp 58:23 I show you how to connect the power supply to the chassis. I would check the power coming out of your 240VAC outlet and ensure you have the correct polarization before hooking your amp to the 240VAC outlet. This is the plug that I use on my M3S. www.amazon.com/gp/product/B078S9HGKX/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 With regards to wiring up your 240VAC outlet, I got an electrician wire up my 240VAC outlet. I hope this helps a little.

Is that correct? 2.5W driving out 512W on 40m? did you modify the pad attenuator for driving it with low power? Thanks.

Good video - Looking at one, like the build process --- K4PAD

Hi Captain This is VU2MB and I build a kit from PCBs and just need a little help from you. Can you please let me know the length of loop cable end to end and circumference of the loop. Thank you 73 Bhanu

[@DarrenN4VFR]

Hi Bhanu, I'm sorry to not get back sooner. I've been so busy with life stuff... I'm not sure of the length and it's not really accessible to get to my Mercury IIIS. Perhaps, send an email to Kenny KM3KM to see if he can give you an idea of the length of the loop cable. Sorry.

[@Alessandro572]

40"

[@mbsingh4597]

40 inch is too long. It should be around 24 inches. Did you meant 40cms?

[@mikegianfrancesco9431]

Can this do remote

[@DarrenN4VFR]

No, because I have no way to put the amp offline so I can tune the tuner and antenna after changing bands. I still need to figure out remote operations to my SunsSDR2 first.

[@jquintana7097]

Which do you like best that one or the rfkits? I had seen your other video.

[@DarrenN4VFR]

For total remote control i prefer using the RF2K-S.

[@thomashenderson603]

Awesome Video! Do you think you got this sooner because of the kit?

[@DarrenN4VFR]

I ordered in December 30th 2021. I wanted a kit so I put it together as a project. I don't know if the kit version arrives earlier then the fully assembled one. I would think it would take longer if you ordered the fully assembled version. Send them an email. Good luck on your decision.

[@RandallRash]

If I get an amp, you have sold me on this one. It is really nice looking. KR5EEE

[@DarrenN4VFR]

I happy to make and convince you. I get no kick back for this company. Strictly my entertainment to you all.

[@mikegianfrancesco9431]

Sunsdr I believe they have remote software and the amp you have dont they have remote software to do all that

[@frantech6935]

Let's go Brandon LOL 😀👍

[@mikegianfrancesco9431]

Lets go Brandon

[@DarrenN4VFR]

Oh, you saw that!? lol

[@mikeerstad3705]

I can see why they don't have kits anymore....I said to a friend that a monkey could do this and he said there are some stupid monkeys........Appreciate the video, but no matter what your daily job is, it doesn't mean you have good soldering skills....and you don't ....

[@DarrenN4VFR]

But it works.

[@modex20]

I can’t stand Biden any more than the next guy. But plastering political memes on your rf gear is kinda cringe.

[@lmamakos]

Is that really an option that they offer? Do they think that will yield more or less sales now that potential customers know of their political views, I wonder? Makes me think twice, now.
