In the Icom 7610, there are two ADC (analog-digital converters) that in some rigs an issue with the heat sinks have either become loose or all together falls off. There was an issue during production with certain radios where this was an issue. My serial number did not fall into the run that had this particular problem. BUT I did want to double-check to make sure I had no issue with the ADC heat sinks. I have had very good luck with my 7610. As most have heard the Icom 7610 has a notorious issue with their screens. My rig now is over a year old and I have had no screen issues and I hope I am safe to say that I am out of the woods......but if something does come up with my screen Icom has said that all screen issues are covered no matter the date of your rig.

| No issues with heat sinks. |
Back to the ADC issue, today I decided to inspect the ADC heat sink to make sure there was no issue. I removed the bottom cover and was thrilled to see both ADC heat sinks were without issue. I know my radio was not one of the production runs that had this issue but it does not hurt to check.

Good article. Do you know where there may be a list of serial numbers for affected radios, if there is one?

Good evening Patrick and thanks for stopping by and taking the time to leave a comment, Icom provided a service bulletin were the covered serial numbers are given. Here is the link to the service bulletin:
https://icom.custhelp.com/ci/fattach/get/15904/0/session/L2F2LzEvdGltZS8xNTg3NjgzNzI3L3NpZC82QlJBeTlIbw==/filename/IC-7610+IA-Technical+Bulletin+Heat+Sink+062718.pdf
In the document Icom indicates the affected rig have the serial numbers between 12001000 – 12003470.
I hope this helps and have a great rest of the week and upcoming weekend.
Stay safe Patrick.

Hi Mike,
I bought mine used in July, SN:30XX and have had zero problems. I guess the screen failures scared the first owner. The big stress test will be in September for the Texas QSO Party. It will be on for over 12 hours the first day and 7 the next. Thanks for the post and the link to the PDF.

Good evening Larry very nice to hear from you and thanks for taking the time to read the post, I have had no issues at all with my screen and mine is about 1 1/2 years old now and I purchased it new. I am thinking that if nothing at all has shown up by now I am good to go. BUT if any issue does come up Icom is looking after it anyway, so I am not worried. I am taking part in all the QSO parties hoping to make some contacts in all the events. I will be taking part in the Texas QSO party and maybe will make contact.
73 Larry and stay safe.

Mike, odds are slim as you are a CW guy and I am a SSB guy.

Good evening Larry sorry for the late reply but I have been very busy here at the new QTH, well Larry it’s very true that if you are an SSB gent, and I am a CW gent the meeting on the air is slim to none……unless FT8 digi is allowed then we are golden for a contact!
Larry thanks for getting back and stay safe.
