#72 HAM Radio repair: ICOM IC-7000 with receiver problems and remote failer
HTML-код
- Опубликовано: 29 авг 2024
- In this episode we exam a IC-7000 with an odd receiver problem. Additional to that rig can't be controlled by PC via remote.
As maintainers we have to swap the back up batteries.
A really darn good video. We all in here do enjoy these nut and bolt diy type repairs. Excellent analytics. Well presented and much appreciated. Thanks so much!!!!!
+Satellite_Guy Hi, thanks you so much! Take care my friend! 73
Peter, you are a genius, what great work. Always look forward to your videos. Thanks for taking the time to share your troubleshooting skills. Have a great week.
+rupert handford Hi Rupert, thanks for the kind words! Have a great week as well !
thank god you are showing proper procedures on the youtube. thank you, peter, you are a blessing.
glad that it makes sense to you to watch my videos! 73
You sure are talented Peter!!!!
Very impressed by your talents and skills
Dan
Again really glad that you like my videos, Dan! All the best and 73
Peter another success these ribbon cables seem to be a pain they seem to be a weak link in the radio it was great you got the remote sorted out to control by computer well done :)
Great diagnostics again here Peter and awesome to watch you work through it. Thank you
Cheers
John
+orbiter8 (John) Hello John my friend, thank you! When can we expect another nice video from you? Love to see your new microscope in action :^) Take care!
+TRXBench New video coming today Peter 😊.. Its only a basic one though so no need for microscope this time, sorry.
You have fantastic troubleshooting skills my friend.. I am learning all I can from you. I am going to be your Apprentices for awhile ......Thank you for all you do....
+Chris „Sir Cable“ Ortiz Hi Chris, thanks for the kind words! I'm glad that my videos are of any value!

Hi Peter...very interesting repair. Regarding the chip inductor being burnt out, I had a similar problem with an Elecraft K2, it appears that at some point the ground connection to the rig PSU had become disconnected so that when the rig was switched on the rig tried to draw current via the computer ground connection, thus burning out the chip inductor. Unfortunately the user just tightened the PSU ground connection not realising the damage that had been caused. Something to watch for on any rig/computer combo. Hope this helps. Steve G4EDG
I hope that the owner will be satisfied at 100% for your work on this rtx.. '73 :)
Yes he is Alessandro, thanks for watching 73
Thank you for this video! it helped me diagnose and fix my remote problem with mt Icom IC-7000! 73's Mike WA3O
Wow, that ICOM was a little trouble maker. Good repair Peter!
Well, we went to the Christmas tree farm, and the tree is up now, Marie has me busy with lights..... All the old stuff too, no LED's in our tree. ( Note: if you put LED's in your tree, the Grinch will come.)
Hope the Christmas season is treating you well :^)
+Mr Carlson's Lab Hi Paul, yeah it was a real troublemaker but it is up and running:-) It really takes time to get all the lights up but it looks really great. No Grinch to come :^). Tree must wait for another week but that is usual here.. All is very well here, hope Christmas season is treating you also well! Take Care!!
Fantastic troubleshooting and repair, great job again.
Bud...
+budleyca1 Thank you Bud!
I enjoy your videos. They’re educational and entertaining. Thank you!
Great job again Peter. Seems those radios really have an issue with ribbon cables. Seems those are as bad as Kenwood TS-940. Have one on bench with the "Dot" problem. Between the PLL's and wire connectors it is driving me crazy. Need to fly you over here for some support :) Thanks for sharing my friend.
+The Radio Shop Thanks Buddy! Take care!
I worked for Icom for about 7 years and in the era of the IC-7000 and IC-7100. The 7000 was a very problematic on all levels. The 7100 had many problems as well. Every new Icom design rig or radio always has multiple common and not so common issues. I would never buy an Icom rig or radio until at least 1 or 2 years past it's first release to iron out some of the problems.
Hi Shane, thanks for the feed-back..that is what I always thought....All the best and 73
Shane, have you ever seen an IC7000 with good power on all band but lack of power on UHF ? I replace the final (RD60HUF1) and power increase from 12 to 23W watt but still no full output. When I dail the band while transmitting into a dummyload I get max 28W at 421MHz.. A very strange problem it seems.. shortwave + 50MHz is 100W, VHF 50W so driver seems to be okay.. Any Idea ?
@@johnpeters1921 My "new" IC-7000 lacks power on UHF too. It is only 5 W or so. I didn't replace the final yet.
Thank you for sharing your very interesting repair of the Icom 7000. Hope my 7000 wiil not be affected by these problems.
Thanks for feed-back ! Yeah the IC-7000 has some nasty issues...73
Peter: Well, you inspired me to upgrade my shop. So now I added a Racal Dana 1992 counter to the workbench. It works great! Would you please do a video showing us your test gear and how it's connected and used? Thank you!
Thanks again for your video dear Peter. Very nice job. 73s Pasquale IW0HEX
+Pasquale IW0HEX Thank you Pasquale. 73
Another great repair! Thanks, Peter.
+Robert Calk Jr. Thank you Robert!
Hmmm, IC7000 ribbon cables, Deja Vu all over again! Nice job as usual Peter. 73 - Dino KL0S
+Dino Papas Hi Dino, yes Deja Vu...Thanks for comment! 73's
+TRXBench Thanks Peter for the lead over to orbiter8's channel, have subscribed.
+Dino Papas very good, John is a very nice person! 73
THanks for the repair video Peter . Great Job
+Grant Fullen Thank you Grant! You was able to help Buddy, right? That is really great! 73
Good video. I have had problems with these stinking cables my self.
Yeah really stinking cables..
Thanks for the video Sir. It was very helpfull 73's
Great work again
thanks for video Peter
+DENNIS N Thanks Dennis!
These Flat Foil Cables (FFC) are a very difficult thing to handle in maintenance. The video clearly shows, that someone already pulled them out and in several times. The contact area of several lines where broken or folded. One needs to remember that these foils and the corresponding plugs are only made for 12..20 contact times.
From what I can see in the video, ICOM does use static connectors, that do not have a handle to release the FFC. So the risk of damaging the foils contacts is 100 times higher than compared to these ZIF connectors. You have to take care to push in the cables exactly straight downwards. Only a small angle deviation from 90° and the connectors contact pins will peel off the foils contacts.
You can make yourself a special tool, by using angle pliers where you glue some small ribbon tape on the inside. With that you can easily push in and pull out these cables, maintaining equal force on a wide area of the foil.
+Astralix2011 Thanks for comment and the additional information!
Hi Tony! I only added a hopefully helpful advise for the public. And if the public has an additional advice, it it very welcomed! I am not sure if it is always a good idea to use the FFC sockets with the release handle, cause ICOM designs for mobile, airborne and military use. And under vibration it is a totally different thing to use a plug that is either self opening or extremely more expensive compared to a simple but uncomfortable solution.
I have seen Peter doing some excellent repair work on many Icom IC-7000 transceivers. - Much respect to Peter, his knowledge and his skill.
I do like the look of the IC-7000, and would like to own one. Are they a good radio if treated with respect and not run at full power all the time? Or is the Icom IC-7000 a radio that's best avoided?
Your repair video's are too important in saving mankind lol .
+Zeproo LOL, well I don't think so. Anyway thanks for watching!!
+Zeproo LOL, well I don't think so. Anyway thanks for watching!!
Great Video again. I have a question. Could the reoccurring problem with the ribbon cables be connected to the fact that the IC700 generally runs hot ?. It seems to me that the ribbons cold be de-laminating with time. Thank you again for your great videos 73 Konrad- KC9NUW
+Konrad Kubit Hi Konrad, well may be I can't verify and proof it. But you are right it looks like that the cables are de-laminating... Thanks for watching and comment!! 73
Once again,great job!
+Chrysiotis Hi Jim, thanks you so much! Have a nice and happy 2016. 73
Can you elaborate on the Adjustment of the reference Osc, not seeing where it is in the manual and where did you hook up to see the frequency 124.003mhz?
Another great video Peter. Looks to me like Icom needs to improve the quality of their ribbon cables. They don't look very durable to me.
+jerry blood Thank you very much Jerry!
I may have asked before, but could the problems with the ribbon cable be due to the high temperatures the radio produces? I keep an external fan on my 13 year old IC-7000 and all seems to work fine.
The "Ribbon cable man" :) Got one of this my self, had a broken fet-driver asvell.
lol yeah
@@TRXLab Umm Peter... Mr Carlson is here... running behind a chair
Ahm what?? Not a clue what you mean...
@@TRXLab Mr Carlson's Lab has comment this Icom down here :) I follow him aswell
The ribbon cable appeared to have been subjected to some thermal stress. Did you test the unit for a long time with the case enclosure completed? Perhaps there is a fan issue or, as you showed, a loss of thermal transfer between components in the final and the case that raised heat inside. Although regarding grease I would offer that heat transfer is not terribly bothered with the lack of grease; it is used to "fill in" any mechanical gap between the component and heat sink.
I'd be a little more curious about those cables and what may have caused them to fail.
Maybe, as you guessed, a previous repair (flux left behind) may have damaged the cables?
+k1mgy Hi Mark, well a lot of possible root cases which I'm not rally able to verify. But it is a kind of fact that this radio is running very hot itself . The fan is working for sure and yes may be it is possibly a result of an earlier repair? I know that the grease is only a gab filler but you always have a kind of mechanical gab therefore it is essential to have grease in place. Thanks for comment! 73's
@TRXlab can you recommend someone to repair an Ic7000?
What about an IC735?
Many thanks
Love the videos
What is the purpose of that battery you replaced? Thanks. Your videos are fantastic!!!!!
Why is are the flex cables damaged? Because there is flux residue on the main board :)
My IC-7000 just lost tx and rx, the alc is full scale on hf ssb with no audio in, I see the problem is not uncommon but I'm finding no solutions. Have you seen this, any ideas? It seems like it maybe lost a voltage somewhere.
Very interesting, thank you! I'm worried that I might need to consider 'preventative maintenence' to my IC7000... Dry heat paste worries me :/ best 73 from ZS6JV
+MrSharkyZA Hi Jaques, yes you never know. It is embarrassing that a a-brand manufacturer is delivering this.. Thanks for comment. 73
Nice job well worked out.
+Gary g1fsh Thanks Gary!
Nice video. Clearly the ribbon cable was faulty but how can you be sure the missing heat sink compound was not causing problems as well?
+TheDisorderly1 Thank you, well the problems was on receive so we can preclude that there is nothing wrong with the driver even we have the missing compound.
Peter... do you accept radios for repair from the US? What is required? Thanks.
Really with all the custom issues and shipping costs it does not make sense. But you can contact my friend Buddy from" the radio shop" in NC he can help!
Peter could you please informe about the S9 adjustment on IC-7000? It must be with preamp on or off after an -73dB inserting?
Hi Spiros, preamp has to be switched ON. 73
Thanks
Many 73
Spiros, SV1DPP
it seems to me that you permanently damaged at least one of the 4 plastic 3.5mm connectors with the heat gun set too high, or some other source of heat you used to desolder the inductor
I am familiar with that feeling of surprise when finding a component without thermal grease.
I try to give the manufacturer the benefit of the doubt and blame it on the golden screwdriver, but when you start seeing repeat offenders, you start to question the factory’s quality control.
is there a lot of current running through the ribber cables?
+Matt K Hi Matt, no not at all only low current flow... 73
Hi All to Anyone interested, as seen below i have an IC 7000 that is about 3 Khz off freq on 70cms and about 1 khz off on 2 mts, on tx and rx, hf isn't far out, but apparently there is only the one thing to set, there is no adjustment inside the radio, and the REF in the OTH menu only goes a few hz either way, but if you go into the hidden menu, see Bib Nagy video on that, using a a jack plug in the back you are supposed to be able to move it about 5 khz shall we say, at least, the numbers are in Hexadecimal, mine is on AD, now i tried to change it, i went form 00 to FF that's the whole range, and it dint alter it at all, i was supposed to, so i am now sending it to Icoms in Kent,,,,just thought someone might be interested hi...seems the radio must have a fault on....from Fred g4vvq in England.
I have a Icom 7000 with no RX ON VHF and UHF but Transmit fine any help on this issue?
Well must be a issue in the front end but can't point you to a component... 73
I have exactly same issue on my 7000 and send it to Icom Canada service team, finally they told me it should be replace 3 MCBs due to difficulty, I am almost crazy on such report. If anyone who have any idea in circuit, please reply advise with thousand thanks. :-)
what's a "ship" inductor?
Thank you
+hussain alonzi Thanks Hussain!
Der Konkurrenzkampf wird durch Verbilligung der Waren geführt. - Marx
Whilst you think you're getting an ICOM, you're really getting a rig designed, verified and manufactured by the cheapest outsource company. Which may out source again to another cheap company.
Quality craftsmanship and pride is a cultural thing. Some cultures don't value it any more, some never did.
More Teutonic or Japanese thoroughness is required!!!
:-)
+Peter Walker Peter and that is the point! As Kenwood is top of the pop I don't like to say where I see ICOM..
Yes Peter, forget Marx; the Teutons are good at convincing themselves of their superiority.
If they'd get off their soap boxes they'd see the hubris they're heir to. We all make mistakes but those fellows far too often won't accept this. This is a problem. They inadequately design many things and the thoroughness you mention isn't there, yet you can't get through to them. Uttery impeacheable they are. It's cultural. They look as silly to the rest of the world as americans (small A).
Once they get a bit of humility like the rest of us then they'll be more like the Japanese.
Hello, l am trying to buy a good reliable 100W radio could recommend anything?
Hi Dave, well I would look out for a nice Kenwood. Not always the design winners but very nice radios. 73
Kenwood has very nice audio. I started with a Yeasu FT857D mobile "shack in a box", which according to my Bird meter puts out between 98 and 102 watts HF, but the audio leaves a lot to be desired. I bought a couple of older 1990s, late 1980s Kenwoods. One had a bad mic preamp, and the other had bad caps in the audio output, which fried a chip, but after repairs, they are both keepers, especially the one with the built in antenna tuner. The Kenwood transceivers all sound very nice even without external speakers..

Peter, How long have you been doing electronics?Don't you know there is no such thing as a simple fix with anything you do.I mean to change the spark plugs in some older vehicles you have to tear the engine half apart . Simple fix .well how about just a fix.
What a fucking mess of the chip coil, totally savaged up the 3.5mm jacks. An absolute horrendous job a 5-year-old could do better with today's equipment. I've replaced chips smaller than that and the finished job was perfect with NO surrounding damage. If I was the owner of this radio id be pissed and would have told him to replace those too. Also said he couldn't guarantee how long it will last.....if the job was done properly it would have lasted. Total NOOB.
sorry 124.03mhz!
