ADVANCED OPERATIONS
Operating PSK
A PSK encoder/decoder is built into the IC-7760.
Using a USB keyboard and contents set in the PSK
TX memory, you can do basic PSK operations without
using an external device or software.
L If you are using PSK software, refer to the software
manual.
D Displaying the PSK DECODE screen
With the built-in demodulator and decoder, received
PSK signals are displayed on the PSK DECODE
screen.
L The decode screen for the RTTY mode differs slightly
from that of the PSK mode.
