Specifications

2. Transmit by computer generated PTT or WinKey PTT.

This setting is displayed in the MIDDLE picture and indicated by the second letter of the settings (ACmA).

The current operating state is indicated by a large black frame around the switching picture.

A: Computer audio is disconnected from the

radio and the station microphone is connected

directly to the transceiver microphone jack. This

setting is for VOX operation.

B: Computer generated audio is routed to the

transceiver accessory input and the station

microphone is muted. This is the preferred

setting for digital mode operation (AFSK, PSK,

etc.) when the computer generates a PTT signal

on a virtual port.

C: The station microphone is connected to the

sound card microphone input and audio output

from the computer is connected to the radio's

microphone input. This setting is similar to “A”

but microphone signal goes through the sound card. This configuration is useful for voice keyer operation

(DVK) and is the preferred setting with N1MM Logger, Win-Test, or WriteLog.

3. Transmit by foot switch or hand mic PTT.

This setting is displayed in the BOTTOM picture and indicated by the third letter of the settings (ACmA).

The current operating state is indicated by a large black frame around the switching picture.

A: Computer audio is disconnected from the

radio and the microphone is connected directly

to the transceiver microphone jack. This setting

allows the operator to interrupt a DVK message.
