Timewave PK-900 - Tuning in FSK Narrow and Wide Stations

10.2.1 Tuning in FSK Narrow and Wide Stations
Tuning in the Frequency Shift Keying (FSK) signal properly is critical
to successful SIAM operation. SIAM can only decode a signal properly
if it is tuned correctly. Follow the tuning procedure below carefully
for the best results in tuning HF FSK stations.
o Set the default Signal Identification modem (QSIGNAL) to the
number you wish to use.
o Make certain your HF receiver is either in LSB or FSK depending
on your PK-900 setup.
o Turn OFF any IF-Shift and Passband-Tuning controls.
o Tune your receiver carefully across the band looking for the
distinctive two tone sound of an FSK signal.
o When you find a station, slowly vary the VFO tuning knob on
your receiver and look for a display on the PK-900 tuning
indicator like the one shown below.
