Specifications

Follow the tuning procedure below carefully for the best results in
tuning in HF packet stations.
o Make certain your HF receiver is either in LSB or FSK depending
on your PK-900 set-up.
o Turn any IF-Shift and Passband-Tuning controls to the Center or
OFF position.
o Tune your receiver to 14.103 MHz (or another frequency where you
know there is HF packet activity) and listen to the packets.
o Slowly vary the tuning knob on your receiver and look for a
display on the PK-900 tuning indicator like the one below.

If the tuning indicator looks like the one below, the audio
frequency from your speaker is too low for the PK-900 to copy
packets. Slowly tune the VFO and make the frequency higher.
