Radio base stations

I used a Tentec radio as a base station and crew radio for many years.
It worked well at home and in our various motorhomes, my wife liked it,
but it got old (25 years) and got cranky. I replaced with with an iCom
A6, but my wife doesn't like it because it is not nearly as noise and
interference tolerant in reception as the old Tentec.

That opinion is based on using the A6 and Tentec in the same place,
within a few minutes of the other one, on the same power supply and
antenna. Without question, the Tentec is much quieter, even with the
squelch set on the edge; the A6 typically needs the squelch cranked up
to 18-22 (of 24) to keep it from hissing.

So, now I'm looking for a base station that has good reception and can
tolerate the noise that is often present in a home or motorhome. The two
main choices look like clones of each other, but I'm open to suggestions
for other radios (even handhelds): the iCom A110 and the Flightline
FL-M1000A.

Does anyone know what would make a good base station for my situation?
Or some way of improving the iCom A6 noise tolerance?
