Soundcard Interfaces - Often, hams will use a soundcard interface to make the connection between their computer's soundcard and their radios. This offers many advantages, not the least of which is good isolation and suppressing problems such as hum and ground loops.

Terminal Units - These units require a display of some kind (PC, video terminal) to function. There are some, like the PK232 series, that have been updated to keep up with new capabilities, while others, such as the M-8000 are of limited usefullness since it copies modes that have long since been abandoned.

Terminal Unit Support Programs There are only a few programs available today to interface with the terminal units listed above. This is a rapidly dwindling category as more and more decoding is being done at the software level.

Readers - These are units that usually have their own display, in the form of a LCD readout. These kinds of units have been on the market for many years. Sadly, though, for many people just starting out in the digital hobby, these units become rather out of date for their time. They don't have any upgrade path, so new modes cannot be added. There still are some being sold on the market, and the potential users should be aware of this rather big pitfall.
