this is some fine workmanship. awesome. thank you.

Very Nice, I just repaired a 7000 that someone had accidentally applied power to it in reverse polarity. The radio was a bit of a mess but it made a full recovery. I had the exact same issue with the ribbon cables. I had only one contact fold over on me. I was lucky that I was able to re-insert it without folding the contact over again.

Good to see another successful repair. I am sure your friend is really pleased to get his radio back again in working order. As usual look forward to your next project.

I had this problem with my IC7000. The replacement driver board was cheaper than replacing the the burned out FET! I was surprised that no heat sink paste was used between the driver module and the chassis when it was manufactured. No problems since this repair. Steve G4EDG

As Paul said, Great Job!!! I can understand and be a lot more forgiving towards the average guy doing his own repairs, but for a company to engineer a product with those issues...don't think so! Even I can think of ways to use ribbon cable that would not have presented the problems with that radio. You did an excellent job, though I know you felt like kicking yourself for not replacing the ribbon cables when you had it apart the first time. The previous video of yours that I watched before this one has me concerned about the quality of components. It was a Kenwood 850 I think, and capacitors had leaked out all over the board...and even with your talented cleaning of the board, it was still seriously damaged from the leaking caps. Even old vacuum tube radios from the 30's and 40's had electrolytics that didn't leak that bad or quickly! I would love to visit your shop some day and spend some time sharing stories with you and learning from you. Keep up the excellent work.

Again.. loved the video. Interesting that some of the four pin connectors on the driver board were all joined/soldered together to form one large conductor.

TRX, Your presentations are most enjoyable. Very under-stated style and a wealth of knowledge and methodical troubleshooting. Was going to state how much I detest ribbon cables but another poster beat me to the draw. I despise these connectors! They have curtailed my amateur radio activities as my Icom 745 has broken and rotted ones and I cannot get any sort of replacements. Why is the production and availability of ribbon cables such a secret? Can't some business provide custom made ones if they have for example, a sample of the original cable or if they know the connector type, pin size etc? With the Icom 745, jumper wires may be a sort of solution but where can one get the right size connectors for the individual wires? Ideas, anyone?

In the past, when working on computers with ribbon cable problems it was usually the very end of the cable that would fail. I used to take a pair of sharp scissors and trim off about an inch if the cable allowed for it. It worked every time for me. Would that be possible in an RF circuit? When I was looking at the cable in the video, I was beginning to wonder if the cable had been flipped over or even reversed end for end. My hunch is based on the shape of the cable and how it fit once installed. As always, I truly enjoy watching your videos. Awesome and Free! Point the complainers to the door. LOL. Heck, you don't need my compliments. ...Looks like you get flooded with compliments regularly. As others often say, thanks for sharing your time and your expertise with the world. Question: do you have a video, or would you consider making a video that simply gives a tour of the equipment you own and its purpose? I mean all the items on your shelves in the background. Perhaps some items are duplicates, but you have things that I have never seen before.

Those IC-7000 radios have a problem with their fuse holders. If you remove the fuses and clean them really good you can see if your wattage increases. Mine was transmitting ~100 watts on Field Day one year, and after 30 minutes into the contest the power suddenly dropped to ~40-50%.

@goinghomesomeday1 This radio is just cheap and nasty, its predecessors had 2 drivers with parasitic suppression, this radio doesn't; the cooling is insufficient with a fan half the size of the 706MKIIG, and you can see this if you turn on the temperature display on the front of the radio. A 10-second over on full power is all you can get before the radio is overheating. The driver mount is not smooth, and there is no heat sink grease to bridge the gap between the transistors and the case. In my opinion, if they had put the colour display on the 706MKIIG radio, you would have had a great radio combination, but they didn't and the IC 7000 is a bit of a disappointment.

Does any one on here have trouble when turning the memory left bottom control, the display flickers all over the place and if it really bad the relays inside the radio keep chattering, have cleaned the terminals from display unit to radio when you remove the front, there are about 6 gold terminals...cleaned them with switch cleaner...have 2 of these and they both do it...cure is dont use the memory from Fred g4vvq.
