F. Winlink VHF Operation — Hardware Setup

The information in this section is for reference only. The radio is set up for Winlink

using the Timewave PK-96 TNC, and you should not need to access these settings in

normal operation.

The TNC is connected to the radio's DATA2 connector. See Figure 4.

Figure 4

Several configuration parameters affect the TNC performance. These are found in the SET

mode under the Connectors and Function menus. The IC-7100 User Guide is a little

fuzzy on the details. By experimentation, here is what I found.
