Welcome to the UMC Hardware page. On this page, we have links to:

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.

Hardware Links Websites that have other information on these decoders are presented here

Readers and Discontinued Units - Readers are units that usually have their own display, in the form of a LCD readout. These units are very much out of date. They don't have any upgrade path, so new modes cannot be added. There still are some being sold on the used market, and unless you have a specific need, there are better (software based) solutions.
