Modem for Packet Radio.

 

 

The Modem-Pac is a an interface for packet radio operation with 1200 Bd on amateur radio VHF/UHF bands. The modem is constructed by using the highly integrated CML modem chip MX-614.

The Modem-Pac hardware consists of a passive modem on one of the PC's interfaces, or a simple slotcard with serial communication controllers (but without CPU), to which passive modems may be connected, so no TNC (terminal node controller, a small microcomputer, usually with a Z80 CPU) is required to interface the PC to the radio.

The functions of the AX.25 communication protocol are performed by the PC software itself. This makes our hardware cheaper and less complex than TNC's.

Modem-Pac hardware may also be used in conjunction with numerous other software drivers. The most important ones are the AX.25 driver like AGW-PE, TFPCX and the various FlexNet drivers, terminal packet programs like Baycom,(a user friendly program suitable for beginners) and some of the most popular APRS programs like UI-View or Winaprs can connect to Modem-Pac hardware.
