Re: donor ic7000
Hi, Why is the logic assembly sitting on top of the radio? What do you mean by relay vibration issue? Thanks Tommy KF4RWG On Tue, Mar 18, 2025 at 12:26?PM Prabhu via <vu2cck=[email protected]> wrote: Hi , |

Looking for parts, band down button and stand
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
开云体育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 ?

Nice job! I wonder if someone changed those caps for a particular reason or if it was a factory?change that didn't make it to the documentation??? Bob W4JFA On Wed, Mar 12, 2025 at 10:35?PM Craig- KB4RU via <ki4coa=[email protected]> wrote:

Re: Fixing the unrepairable IC7000
If it was the two Tants, then, their main issue was going SC intermittently!!
