ZX Courier. Good news for 5030 and the rest!

I made a modem for an IBM computer, compatible in commands with Mr. Hayes, and
in communication with comrade Vicom. And I christened it
>Russian ZX Courier 2400.
A loud name, but the essence is not weak.
In terms of schematics, it is extremely simple, but since I made it (including developed
the circuit, of course), then I’m waiting for offers of reward. Otherwise I want to eat, and
I don’t mind playing.... ;-)
In general, I’m ready to give the circuit (not the device!) for 14400, Sprat for example. I would really
like to find a voice in it.
But I started making the circuit for another reason - I’m going to make a radio modem, at least
9600. Otherwise, soon it will be time-based, it will be sad. And then I’ll throw in a diagram!;-)
And about 9600. Why not make one like this in ZX?
