NUE- USB Card Manual, ver 1.34

NUE-PSK Digital Modem

USB Card Operator’s Manual

(For use with modem software v1.34 and later)

The

NUE-USB Card

is an optional low-cost addition to the NUE-PSK Digital modem that

increases the enjoyment and capabilities of the digital mode operating experience. The USB

Card plugs into any NUE-PSK modem to provide the ability to record the receive and transmit

QSO text to a removable USB flash memory device (“thumb drive”) for archival and remote

printing. The USB Card also provides a serial connection to a PC, a means to upgrade modem

software from the thumb drive, and a port for a USB printer. Traces are present on the pc board

for custom addition of a real-time clock/calendar function ideally used for timestamping QSOs.

The modem software (v1.33c) associated with this USB Card hardware release contains

improved keyboard commands for controlling the USB card functions and a wonderfully-

revamped and consistent set of text editing commands.
