6. Switch Settings and Initialization. The following tables provide the necessary switch settings and

communication parameters for interoperability. The switch settings for the local RT (connected to the

KY-90) and the distant RT are different. RT switch settings should be according to Tables 6-1 and 6-2

for distant and local radios respectively. Initialize the KY-90 for communication as shown in Table 6-3.

Verify all settings for both the distant and local radios and the KY-90, then establish communication on

the net.

NOTE

If operating in Plain Text, distant RT goes to PT, local radio is set to SQ ON, and KY-90

goes to PLAIN. Distant radio should wait 5 seconds after keying before speaking.
