VI. USING the USB CARD
Three main features are enabled by having the USB card installed:
REC mode
,
Flash Bootload
, and
PC
Bootload
. These three features are very powerful and will greatly enhance your digital modem
experience.
Remember, you must have modem software v1.33c (or later) for these features to work as described ...
and
you must have firmware "C01" loaded on your USB card.

REC MODE -- Records QSOs to a USB flash memory device
Insert a USB flash memory device into the modem connector. Again, that LED may or may not come on.
Type Ctrl-U on the modem keyboard to place the modem into RECORD mode. You will see “REC”
displayed on the right side of the modem display and the LED on the USB port will start blinking rapidly,
indicating that it is ready to receive any text that you may type in Tx mode or any text that is coming
across the LCD in Rx mode. (Note: If the USB card is not in place, or not working, the REC will be
shown briefly on the display and a beep will be sounded by the modem to indicate that an error condition
is present.)
Assuming things are working (no beep and the LED blinking rapidly), place the modem into
Tx mode
(press F10)
and start typing some text. You do not need to be connected to your transceiver to try this
out. You will see the text displayed on the modem LCD of course, but it is also being simultaneously
written to your USB flash device.
Type Ctrl-U again to stop the REC mode and you will see the USB port LED stop blinking and remain on
continuously.
Remove the USB device and plug it into your computer. You will notice a new file on the stick called
NUE-PSK.TXT
. If you open this file you will see the text that you typed while in Tx mode, and any other
text that might have been displayed while in Rx mode.
As summarized on the Command Reference sheet, two other USB-related features are available to you.
One is that you may specify
your own unique filename
for the data being recorded to the USB device
while plugged into the modem.
Before
turning on REC mode (CTRL-U), you may type CTRL-N and you
will be prompted at the top of the modem display to enter a filename. Give it any standard 8.3 format
filename that is useful to you. (8.3 is 8 characters followed by a period and 3 more characters as an
extension, like “Test1234.txt”.) Don’t forget to use CTRL-Z key to end this entry.)
The other USB-related feature is that you may
Insert your own text
into the data stream being recorded
to your USB flash device. For example, after getting into REC mode (CTRL-U) but before starting up a
QSO, you might wish to enter the current date, time or operator name in order to have a better record of
the QSO downstream. To do this, type CTRL-I and you will prompted at the top of the screen to enter
this “offline” text. Don’t forget to end your entry with a CTRL-Z in order to return back to Tx or Rx mode.
Remember, what you enter in this Insert mode is
not
transmitted, but it is only text that is inserted into
the stream of data going to your USB flash memory device.
