If you have seamed galvanized gutters I share your pain. I have tried everything to seal the seams over the years. This combination has lasted the longest so far. I have test sections that have gone a few years with no noticeable degradation.
Icom IC 705 QRP SDR XCVR driving the Mercury 3S amplifier by KM3KM
มุมมอง 2.5K3 ปีที่แล้ว
At the request of a friend of the channel I used an Icom IC705 in battery mode, as the exciter for the Mercury 3S Power amplifier. So roughly 10% power gave 1 watt of drive and 10-50 watts out of the Mercury 3. 50% gives 5 Watts of drive from the 705 and about 250 to 280 Watts out of the Mercury 3S. For power levels above that use the graph that appears in my Mercury 3S fire up video. For conve...

Hello! This white paper on my PSR is torn. Could you tell me how I can change it??? Is there a type of paper that I can use to replace the one that tore?

Thanks for the video! I’m looking for a place to install the head unit for my Kenwood. I’ve gotten everything installed except the head unit. I want to put the head unit up top like that. How is it holding up? Anything you would change?
Hey thanks! I just fixed mine with help from this video.
I'm having fade out display of same model psr 520. Can I get a new display? Thank you.
I found mine on Ebay
I'm aware I'm reawakening a comment thread... Is your 888LM for "SUBURBAN" connected to the same opener as the display button? Connected in parallel?
Bom dia. Onde você conseguiu um novo display para substituição?
Ebay
❤
where can I buy these products in Canada
When did they change them from 1300w to only 1k?
KM3KM specs it at 1200W SSB/CW, I have seen near that under some operating conditions. I think you will really enjoy the amp. Really works well.
Fuel instructions read 90 octane or above, or you'll mess up the engine. You used 87 octane. You were supposed to use 4 cycle engine oil, not vehicle engine oil, 20 ounces, and also in the instructions. If it stops operating, you did not follow thoroughly on the instructions. That's what engineers get paid for. Through trial and error, they know what works and what fails. Then folks like you complain that the equipment is not working and junk. How do I know I'm an electrical/mechanical engineer and have this field mower.
Page 6 of the operators manual, Fuel recommendation, minimum 87 octane, Vehicle oil is 4 cycle oil. Page 6 of the operators manual states SF,SG,SH,SJ, or higher. I used fully synthetic SN rated oil which is the highest rated oil. I am an Engineer too. TNX for your observations.
Thank you for your help I repleace both capacitors but still blowing can you help mi with that?
OK Just got this. W/O going hands on not much I can do. I would suggest just buying a replacement.
Wish I can afford this amp
It’s $1K less than a comparable Acom. The catch is the wait. I was on the waiting list for 14 months. It also cost me an extra $1K for an electrician to install a 240V outlet.
@@normdingmore8521 it also can work on 120v
It is very impressive that you measured the noise of the amplifier with good result. Once I asked ARRL Lab to do the same with A filter, not yet tested.
Just change the 10dB Flange Attenuator to a 3dB (maybe 10-15USD on Ebay) and you will get the max output easy with less then 5W from your 705. The Gain of this LDMOS is +/- 25dB and only restricted because of this stupid 15dB max gain FCC rule
Just how lean was it running? Did you adjust the mixture??
As I remember it was pretty lean at idle, around 20:1. I did not check the A/F @ WOT under load. I tried it out and it runs real strong. A plug check indicates it is in the right range. There is no provision on the factory compliant carb for mixture adjustment.
Upgraded the battery to a AKZYTUE 3.7V 4500mAh 955178 Lipo Battery Rechargeable Lithium Polymer ion Battery Pack Available on Amazon
How would you use this amp with an automatic antenna tuner ? say the mfj 998 ? Would i just not activate the the ptt line when tuning ? Is the trx antenna line in a pass thru mode then ?
I use a MFJ998 You use the MFJ-5114I MFJ-5114 Original MFJ Enterprises Interface Cable: MFJ Auto Tuner to Icom For the Icom 7300 to control the tuner and you use the Icom IC-7300 Amp Relay Cable With ALC & Relay Buffer To have the Icom 7300 control the amplifier
I am going to try to fix it. I ordered the little parts from Amazon. On one of the comments says Liftmaster/Chamberlain will warranty these till 8/22 which is true, I called them and they will send me a new one but they are on backorder. So in the meantime I will try to fix ours. Thanks for the video!!!
Great video helped me a lot on building mine tnx
Una verdadera maravilla para el KM3KM..LU3 DKS..
I can't find your next video in this series. You were going to do another on-line test using an antenna. Been to your ProjectsINT site and did see one that you did at low power, but still to a dummy load. I expect to receive my fully assembled one tomorrow and will excite it with a Yaesu FTDX-101D. I'll keep checking back for your next video in this series,
Congrats on your purchase. That is very exciting. Yea, sorry about that. Got sick, surgery and numerous other distractions and endless mega projects. So many projects & so little time. Hopefully I can get that back on the agenda at some time in the future.
Thanks so much for this. The FCC gave final approval for the ready made amp. this week 2/17/22 Looking forward to getting one. All that have the kit Love it.
This a 1500 watt amp? Thanks

Yes the loud BEEP was irritating. Hopefully that option can be turned off or at least reduced in volume.

WHY ARE YOU SHOUTING!!
What type of solder iron did you use for this. I have a 60W solder station (Weller) but I'm thinking I'll need something with more power and curious if you could comment on what you used.
Tube amps have suddenly become abundant and cheap.
Man tube amp for me. Not that I don't think this is cool as hell! But can't afford solid state.
It’s only Money and you can’t and will not take it with you.Enjoy it while you can.👍🎙
Wonderful video and thanks for the inspiration! I have a 705 and have been looking at a larger than QRP option so your video came just at the right time. I also another 5-Watter, the ELAD FDM-DUO, and the Mercury IIIS seems to be an even better match for the shack. I would love to hear any other thoughts you may have since you released the video. Thanks again!

THANK YOU! Just repaired mine. We have, as others have noted, taken LiftMaster up on their extended warranty, and they are sending us a free 889LM, which we'll hold onto as a spare.
My 889 did the same thing
yes, I called Liftmaster and they sent me the new updated version. done and done.
Looks well made.
Yes very well made
Does it support full break in/QSK?
Wondering how much 'construction' is involved? Are components, SMD, toroids, relays, etc mounted or must builder install?
Watch my unboxing video. I show how everything comes as it is shipped to you. KM3KM has done most of the hard work. Assembly is as shown in this video. Pretty straight forward.

Moment of truth….screen goes black, video over. What the heck?! We need an update!
I will try to get an update soon. There was a fire ban here and no power equipment could be used. Now we are being flooded out with monsoon rain. Hopefully I can get some shots soon.
Auto tuner, or external tuner needed?
I use a MFJ 998 auto tuner with it and a 5BTV antenna
