— if you need VARA, FT8, or PACTOR III/IV. Those require modern DSP soundcard solutions. Also, the PK‑232 cannot do AX.25 KISS at high speed (max 9600 baud on the serial port).
The PK-232MBX is a hardware multi-mode data controller that connects a radio to a computer. At its core, it uses an 8-bit Motorola microcontroller and an onboard modem to encode and decode digital signals. Unlike the TNC-2 clones of its day, the PK-232MBX was a complete system. It featured an internal mailbox (MBX) with its own lithium backup battery, a powerful dual-port chipset, and separate firmware EPROMs that stored the operating system.
