I think what you are describing is what all APRS clients have always done.
All you need is a radio and a TNC to go in the "black box" on your diagram.
Even without the PC, the KPC-3+ TNC can work stand-alone for when you don't
want the PC. Or you can go without the TNC at all and use only the sound
card on the PC and the AGW software. Or just put in a D7 or D700 radio
that does it all.

I have a Pico.
It loses part of the memory settings when used mobile.
It has been running in my shack for years with mno problems.
