Icom 7610 Heat Sink, Loose or Detached ADC Heatsinks

I'm an Amateur Radio enthusiast. I love the hobby and experimenting with radios, antennas and software. On my YouTube channel I upload videos on the Icom 7300 and Icom 7610 along with Ham radio software programs. I hope to inspire people to try new things in Amateur Radio.

  1. Has a list of serial numbers affected been determined yet?

    The heat sink in question is a secondary heat sink for this chip, basically overkill and I am sure Icom will have a timely fix soon. If you look at a detailed view of the Anan 7000 they use the same chips set for there ADC but chose to not use a secondary heat sink like Icom did, on both radio’s the main heat sink which is on the bottom of the chip get soldered to a copper land onto the PCB during the wave soldering oven plus as you look close you will see two Philips screws that are at the center of the main board which attach it to the main cast chassis of the radio. Anyone who has ever been involved with manufacturing of PCB’s should be able to understand the above. I kind of feel after the Flex PEN with there radio’s issues about heat sink that once something happens with another companies product its like everything else on the internet today, rumors fly like diarrhea. I am sure we will see a simple solution from Icom and from what I can tell it has only happened on a very small amount of 7610’s .

      Hi James,

      Good to hear from you. I agree, it need not be a huge concern. I’m happy Icom likes the overkill because I’m kinda that way myself sometimes.

      I haven’t seen many complaints about it, but I can understand those who are upset. I don’t want a 10 cent heatsink shorting out something in my new $4k radio.

      On the other hand, I’m a Ham for goodness sake, so I’ll just take the bottom cover off and have a look!

      It does seem like a strange coincidence that the new Flex and the Icom 7610 had the same thing happen with heatsinks. I’ve seen the posts about it too.

      Thanks for the info Jim.

        The board that the FPGA and most of the SDR part of the radio faces down so if the heat sink does fall off or get lose its falling down onto the bottom cover, yes you are right its not a nice thing that would happen on a $4k radio or by now closer to $3k but the amount of numbers that I have seen posted on Adam’s forum have been less then 30 radio’s out of 3000 7610’s sold WW, seems like the adhesive conducting tape may have been a bad batch at the Icom plant in Japan. Hey its not the first time any company has has some slight issues with an OEM part or supplier yet I feel confident Icom will make things right.
        I did watch your YT video which was done very well BTW and as long as an owner unplugs his power cord and removes the top then bottom covers like you have shown can easily check if the heat sinks are in place. The ADC 16 bit package that Icom used in these radio’s is the HD model which temp ranges from -40 degree C to 85 degree C and from temp infrared measurements that one of Adam’s group measured that chip doesn’t go above 70 degree C without the secondary heat sink attached. If you look at the Anan 7000 they use the same chip without any secondary heat sink so this issues has been way overblown thanks to some simple minded VK ham who likes to make video’s and big issues out of small ones.
        I cannot imagine over 3000 7610’s withing a little over 6 months time, maybe not the numbers that the 7300 was doing but give them another two years.
        I like yourself looked at the Flex 6400 yet the Icom gave me two independent RX’s and could be use completely stand alone without any computer giving all the overall performance were the Flex to get the most from there radio’s needed the computer to do that, I guess I am just old scope and I like a good top of the range RX over the fish finder.
        Really like your You Tube video’s BTW plus no add pop ups, great stuff!

    Was thinking about buying a used one but I think I’ll wait until we get a list of serial #s

      Hi Richard,

      I understand, but it might be a week or two for the sn’s. Maybe you can get a better price LOL

      If it’s effected, it’s not hard to check.

      See the post by James too.

  4. I’ve looked for evidence that the IC-7610 built-in LAN port actually works with RS-BA1. So far not a single video showing the built-in LAN working, no explanation, no menu settings.

    Does it work? The radio works as a USB device with ICOM Remote running on a connected computer via USB cable, but does NOT seem to work if ports are forwarded to the IC-7610 IP address, or a LAN computer tries to connect to the Radio.

    What’s up with that LAN port? How should it be configured to work with the built-in ICOM REMOTE feature, or is it best to ignore that port and use USB port 2 ?

    Thanks for an answer., Jeff, W6FCC. If you have interest, join our group https://www.facebook.com/groups/RadioElmer/ and explain how to make this work with the 7610 LAN port.

      Hi Jeff,

      Nice to hear from you and that’s a great question. I have been working on remoting into my Icom 7610 and I’ll do a video on it too at some point.

      I don’t use the LAN port for my desktop PC that is next to my radio. I use the USB cable. I am anxiously waiting for the USB3.0 update so we can start using that port on the radio.

      Anyway I’ll be doing a video and article on RS-BA1 and remote operation in the near future.

      Thanks for commenting and have a great weekend.

    UPDATE: 7-26-2017

    Icom has just released a technical bulletin. “We have found that IC-7610 radios within S/N range of 12001000 – 12003470 could be susceptible. ” – Icom

    Hello, what new about the heat sink in Icom 7610 ?, just check mine today and one get loose in 8 months old 7610 , I don’t know how the chip will work without the heat sink but I know the loose aluminum heat sink inside the radio is disaster waiting to happen especially when we move the radio around , should I contact Icom ?
