The LinxTechnologies HP2 series 900 MHz modules
that you used in your doppler radar radio link no
longer exist, as you had mentioned.
But the company has an HP3 series out now.
If my solar powered FM broadcast band repeater
package ever becomes really useful, then I will
go to a 900 MHz STL instead of a 49 MHz one.
And I will use the HP3 series modules.
There is a lot to learn here, and it will take time,
but I think it will be fun.
