o Adjust the PK-900 front panel THRESHOLD control so that the DCD
LCD lights when a properly tuned FEC AMTOR station is being
received.
After you have an FEC AMTOR station tuned in, you should start seeing
the copy on your screen. If you have tuned in "chirping" ARQ AMTOR
stations, you will not print anything until you enter the ALIST mode.
If you just want to receive, see Chapter 10 on SIGNAL IDENTIFICATION.
