In the pantheon of amateur radio gear, few devices have achieved the iconic status of the PK‑232MBX. Originally designed by AEA and now manufactured by Timewave, this Multimode Communications Controller introduced thousands of hams to packet, RTTY, AMTOR, FAX, and even early PACTOR. Its rugged metal case and familiar DB‑25 connector are still spotted at field days and in shacks worldwide.
: KISS (Keep It Simple, Stupid) is a protocol that lets the computer handle packet framing. It is required for most modern TNC applications. To activate KISS on the PK-232MBX, use the KISS ON command. In many cases, you will also need to set it to Advanced KISS (by using INT KISS ), which is required by software like BPQ32 to run at its full potential.
