Hi, Why is the logic assembly sitting on top of the radio? What do you mean by relay vibration issue?
Thanks Tommy KF4RWG
Hi ,
I am having an icom ic7000 fully intact but has relay vibration issue ,so any friends need for parts or repair it can send across, I can ship to any where fedex,dhl and ups can deliver ,shipping charges as actuals or as per your advice, the price is 400usd plus shipping charges,Radio+original mic will be send ,the pictures are attached here,contact me for more specific details, if some one wants to buy as group you can plan accordingly for your needed parts,

cannot sell to the US.

Hello,
I recently bought a used 7000 and it's missing a few parts. If anyone
has the following parts, new or used, please let me know:
Band down button: MP34 (F)
Desk stand: MP33 (C), MP32 (C), MP31 (C), and MP19 (C) x 4
I've contacted Icom support but those parts are no longer available
from them.
Thanks,

Re: Fixing the unrepairable IC7000
Theres caps smooth the 5V rail, and were rated at 16V, Icom replacements are now at least 25V, Tants. have a life! The low capacity would have caused switching noise on the BUK 12V line, but should have worked. I have had this fault over 20 times with these radios. ? KR ? Andrew ?
