strSQL = "SELECT LS1018c.[capacity]" & _
" FROM LS1018c" & _
" WHERE LS1018c.config" & strconfig & _
" AND LS1018c.boomlength = operatingradius" & _
" AND LS1018c.oprad = boomlength;"

I think your problem is in the Where clause. You're trying to using local
variables embedded in the string. It probably should be:
strSQL = "SELECT LS1018c.[capacity]" & _
" FROM LS1018c" & _
" WHERE LS1018c.config" & strconfig & _
" AND LS1018c.boomlength = " & operatingradius & _
" AND LS1018c.oprad = " & boomlength

Also, I would recommend naming your variables with some form of Hungarian
notation to make the code easier to read and to help differentiate variables
from table fields. For example, you might change operatingradius to
dblOperatingRadius.
