Yep, that was one of my first thoughts. It first happened around 40-50 watts, I
backed down to 10-20, then all the way to 5 and it still rebooted. Thanks!On

wrote:Hi Mark,What transmission power are you running FT8 at? FT8 screams
hard-- it'll max out whatever amount you give it, unlike using voice and some
other modes. So issues with RFI/reflection will be accentuated. Does it work
with lower transmission powers? Does it happen on all bands?Best,FoxOn 1/20/26

one-year ham here!I have a used Icom 7300, about 5 years old, that is
experiencing random reboots when using the digital modes such sa FT8. With alll
standard radio modes, mainly phone, there are no problems at all. When using
FT8, and only during transmission, it will randomly do a hard reboot. The radio
worked flawlessly for about 4-6 months after purchase and all this began.I’ve
used different USB cables, added bead ferrites, and most recently, I used some
of the larger ring type ferrites, like the FT240-3, all with the same type of
results. Most times it will work as expected for maybe an hour then start the
reboots. Sometimes it just won’t work at all and immediately reboot on the
first transmission. I’ve also used different computers and different operating
systems. I’ve seemed to have isolated it to the radio itself. And most likely
the USB connector.I download the service manual and determined that going in to
reflow solder on the connector for me is a no-go. The buried surface surface
mount connector is beyond what I’d care to work on. I’m not really interested
in learning how to rework with a air station on something like this.Before I
box it up and ship back to Icom for an expensive repair, and it’s of course,
it’s out of warranty, does anyone have any other things I can check before I
do? I fear that’s my only choice.Thanks!Mark
