Page 40
Ordinarily, the MFJ TNC will stop displaying monitored packets if you connect
to another station, permitting you to converse without interruption. If
you want to monitor activity while connected to a packet station, set MCON
ON.
To display a list of stations heard since the last time your MFJ TNC was
powered up, type
cmd:MHEARD
AD7I

The last several stations whose packets were heard by your MFJ TNC are
displayed. The entry "KV7B*" means that KV7B was heard digipeating a
packet rather than sending one of his own. You can clear the "heard log" with
the command MHCLEAR.
You can see the settings of the monitor parameters described above, as well as
several others, by typing DISPLAY MONITOR.

help you get started. Make sure that your friend will be close enough to ensure
solid copy, with no FM "popcorn" noise. It's best if you can get an experienced
packet operator to help you get started. If you are both beginners, try to have
both stations in the same room and operate on low power or into dummy loads.
Remove the digital loopback jumper, JMP10. Connect your radio to the MFJ
TNC. Turn on your computer, the MFJ TNC, and your radio. Be sure you have
adjusted the MFJ TNC and radio according to one of the methods described in
Chapter 3. When the other station transmits, the DCD LED on the MFJ TNC
should glow steadily for the duration of the transmission. You can work
