[IC-7000] FAILURE

Mark J Culross
Bill (WY6V):
My IC-7000 smoked the UHF output finals a little more than 2 years ago & I sent it to Malcom Technical Services (http://www.angelfire.com/biz2/mts/) for a quick repair. I have had Scott Malcolm repair several of my Icom radios (I have never sent any of them directly to Icom) & his work has always been excellent, quick, & inexpensive. He'll even do a bench check & provide you a $$ estimate before the work begins if you'd like. In the case of my IC-7000, he was able to repair the UHF failure & also found the soldering in the VHF section to be questionable, so he cleaned that up as well. He applied the new grounding springs & tested everything before sending it back to me . . . it's been flawless ever since. From my personal experience with several Icom radios sent to him for repair (IC-706MKIIG, IC-7000, IC-756PRO, etc.) over the years with a variety of needs, I would personally highly recommend Scott Malcom to get your IC-7000 repaired. Good luck !!

Thank you for your reply. I use the radio mostly portable. This is the only radio I have had problems with. The UHF has never worked however I disregarded this issue as HF is the only mode I care to operate with the 7000.
Give all the problems with this radio I have lost all confidence in it thus I am considering selling it an acquire a Kenwood 590. I am striving to determine whether there is something I did or just a natural occurrence with this rig. FYI mine is s/n 0506425.I was told this early production and wrought with problems so I guess the question is can it be brought to the latest specs and will it be reliable?

Bill (WY6V):
My experience was that after Scott Malcolm repaired my IC-7000, it has been flawless. I would recommend that you send your IC-7000 to MTS & let Scott work his magic on it & I would predict that you'll be very happy with it from then on. Although we tend to hear all about the problems & failures with any radio, there are surely many, many more completely satisfied customers that remain happily silent. It's unfortunate that you & I had to be among the ones that experienced a failure, but again, based upon my personal experience, I would not let that shake your confidence sufficiently to turn you completely away from your IC-7000. Mine is still my favorite radio (even surpassing my IC-756Pro !!) & will probably continue to be so for a very long time. Good luck & have fun !!

The receive is excellent: Quieter than my 7600! I will secure repair though I am leaning toward the TS 590. It is relatively small may not be plagued with the problems of the 7000. The question is how much do spend to correct it vs. buying another radio then of course it isn't worth much in it's current state. I am going to have repaired asap but concurrently I think I will look for a 590.
It seems to me the problems with the 7000 are excessive in numbers; maybe I am wrong but it appears to me the subject failure rate is excessive. I always use an external fan with mine. The standby case temperature ultimately has to be destructive and life limiting. Reliability should be the paramount concern and it seems the 7000 may be compromised compared to other radios available. My 706 MK II G has never had any issues and runs MUCH cooler. The 590 can be purchased for only slightly more $$$ than the 7000.

I would assume at least some of the heat everyone is so concerned about is generated by the TFT display.

I believe you to be correct though it appears much heat is also generated at it's core. My observation is applying a constant flow of air from a BDC fan toward the rear heat sink reduces case temperature substantially;20 deg. F????

Bill,
Stop putting down the IC 7000. Any piece of electrical equipment will fail on occasions. My 706 MK II G has never had any issues and runs MUCH cooler.<<< I must inform you that the IC 706 MK11G, IC 756 PRO3 and the IC 7000 all runs within 1 to 2 degree of each other. I always use an external fan with mine. <<< As per your own words, " I always use an external fan with mine." then the Radio should not have a heat related problem. I can understand that you are and have every reason to be dismayed. But, until you know for sure what caused the failure, quit looking for an excuse to blame the Radio. Have you RULED Out your Power Supply? (30 Amps plus) at 14.0 VDC then total RF output failure. <<<While operating phone SSB my 7000 started drawing extremely high current levels Are you sure the Radio wasn't fed (30 Amps plus @ 14VDC) INSTEAD of Drawing 30 plus Amps? Something keeps bugging me. Why over Amperage and not over Voltage? (((73))) Milverton. ________________________________[Non-text portions of this message have been removed]

You will be very pleasantly surprised at how reasonable Scott Malcom's repair rates are. I was !! And besides that, when he gets done with it, it will be better than new (he does a full checkout & calibration, then leaves it "burning-in" for awhile to make sure he didn't miss anything . . . I have been very pleased with his work every time !!

I put a small fan one mine, but no problems even before that. Question: Has anyone considered placing some fins all around the outside of the case? That would look real COOL. (Sorry 'bout that). 73 Clete ++++++++++++++++++++++++++++++++

This pretty much explains that the problem (at least with driver failures) is not due to excessive heat.

The radio has been to Icom three (3) time for the exact same problem; I have accrued in excess of $500 in repair to have the same malady occur for the now four times.

I wonder if any independent repair shops perform this mod? Has Icom improved the driver unit? The driver is buried in the chassis core and runs class A thus there must be known heating issues associated with it.

All need to search farther on SV8YM's website!

He notes right away that the info on his March 2010 page has been replaced by new info as of April and July 2010. There, he describes his FINAL solution, which was adding small wire heatsinks to the pads of the driver transistors. I.E., there really IS a heat problem, but easily remedied. I have discussed this privately with Mark Krotz, KD5RKZ, and he has now found that info that is, admittedly, a bit hidden on SV8YM's site. * * * * * * * * * * * * 73 - Mac, K2GKK/5 * * (Since 30 Nov 53) * * k2gkk@hotmail.com * * Oklahoma City, OK * * USAF, Ret (61-81) * * * * * * * * * * * *

My call is not KD5RKZ. Not sure where that came from. It is N7MK.

I don't think these little heat sinks are going to reduce the heat felt on the case of the radio in operation. Perhaps Icom had a bad run of driver modules, as has been said many times, there are scores of us that have not had these problems. Mark

I have already bought three driver modules and one pair of HF PA's. Plus labor!
