My two cents
As my first radio, I never used it that much as I should probably have. I went on portable operation a few times, mostly to check out an antenna setup that I could use from within my car.
Sooner or later I decided that the radio was too big and too heavy to carry it into the field (and with field I mean the mountains in my region).
I do not have a “shack” at home, I never installed a decent antenna (system) at my home because of the high noise floor that I have here, I thought it would be fun to operate portable in the field, but the IC-7300 is probably not the choice for that, I think.
