10. Watch as the DMX-40 transmits the answer-validate sequence. This is a short
station ID used when you are responding to another station’s CQ (general call) to
attempt to establish a 2-way communication. If they answer you, then a 2-way has
been established, and communication can begin. Answer Validate is not required if
you make a call and someone answers you."
11. Press ANS once. The button turns RED, and a Type-Ahead Buffer pops up.
12. Type a tilde (~) character, then press ANS again. The button turns AMBER."
13. Watch as the DMX-40 sends the initial station ID, followed by the INFO
microprogram, which is generated when you type in a tilde character. The Type-
Ahead Buffer goes away as soon as the tilde is read out. The final station ID back
to the other station completes the transmission, with a KN."
14. Think up a short message, such as "HI, BOB. HOW ARE YOU TODAY?""
15. Press ANS and IMMEDIATELY type your message. You should be able to type at
least part of the message during the station ID, and then your message will begin to
transmit.
16. Press ANS again to specify your typing is complete. Your message will appear in
the Type-Ahead Buffer, until the station ID has completed, and then it will be read
out one character at a time."
17. You now have a basic idea of how to use the four main transmit functions:
1. General Call
2. Directed Call
3. Answer-Validate
4. Answer
These built-in microprograms (CALL, ANSWER, and INFO) can be customized and
controlled from function keys using RPL (Rig Programming Language) in our
microprogramming system. There are 12 user-defined microprograms. Watch our
YouTube video on microprogramming to get a "starter set" to play with.
