I recently acquired an IC-7000. Had several Icom units before, never 7k, but I am excited by the “ahead-of-its- time” features.
After initial set up the output became erratic - screen fuzzes over on 2M transmit; must turn radio off/on to re-set power; and; very inconsistent tune-up with power on hf bands. ?
I read a lot of “mail” about how the connectors - fuses, plugs, sockets sometimes presented a corrosive barrier ( resistance, bad connection) and that might likely be the problem.
After trying to think my way through this problem - with no success - I decided to take the advice of the mail. I cleaned and re-seated the in-line fuses - no change. ?But after more failure, I decided to spray the fuse holders, all the PL239 sockets and the mic input plugs and sockets.
That did it! ?
A simple spray with contact cleaner in some key points, and the radio tunes like a champ on all bands with full output.
So all the collective wisdom about cleaning contacts - all of them if you can - came true.
Never had this problem before with any radios, but first time for everything. And, I am grateful for the “collective wisdom” and the very simple solution to a seemingly confusing issue.
