I have taken a Sony SPP-A941 900 MHz phone our of a retirement to replace my DECT 6.0 devices which we cant get to work without the crackling overpowering all conversation on all the handsets.

The SPP-A941 base unit has completely forgotten the handset in the numerous years it has been out of use.

Ringing in causes the base station to ring and the handset to beep 4 times. So there is some sort of rudimentary communication going on

Pressing any other button on the hand set causes the handset to beep 4 times with no dial tone despite numerous resets. Sony tech support was completely clueless (in anything beyond reading the manual to me and trying a few basic stops like unplugging and plugging the various parts in again).

There IS a button on the handset which is supposed to switch channels if reception is no good. Not apparently for when you get no dial tone whatsoever.

Is there any way of getting the base unit to link up with the handset please?

Hi,
That 4 beeps means base and handset lost link synchronization. Random
random security code(this is from my memory). One thing you can try is
make sure battery in the HS is good and fully charged and unplug the
power to the base station. Wait for ~5 mins. then turn on the the
HS(push talk button), plug the power cord back to the base station.
If no sucess, maybe either one's radio tx/rx circuit is possibly bad.
