IIRC, the antennas at SAQ are just a small fraction of what they used
to be.
I think not all of the remaining masts there 'carry wires'. So the ERP
may have been much larger back then in the early days of the station.
Maybe some Grimeton visitors who have seen the installation can comment
on this.

it's also quite remarkable that once the range was limited mostly by
receiver sensitivity, while right now by the ability to reject qrm.
SAQ was once in regular commercial service with New York with simple
receivers at the other end (btw. anyone know what rx was used?), right
now people in the States are struggling to receive the signal with the
latest technology (dsp etc).
think how much the qrm must have gone up...
