Do all 90mhz handsets work with bases

Probably no.. There is a small chance they are both the same phone in different packaging, but I doubt it. You could always try.

I see that my statement was unclear.. If the phone looks physically compatible, there is a possibility. If it fits on the base, try it and see what happens if you have no use for the phone and base.

Why not just try it? It's old enough technology that it may work.

I think inter-phone compatibility went away with digitally controlled

Before that they used simple pilot tones and standard fixed frequency crystal oscillators. Assuming you got a phone and base on the same channel, you could likely tweak the pilot generators/detectors and have it work.

After that, they used there own phoneBase communication scheme, and/or subcodes.

The different manufactures use their own frequency and protocol. Only if the units are internally the same and designed to work with the same protocol they will be compatible.

Sounds like a reasonable explanation.
