FIXED and FOLLOW RADIO Audio Switching

Router provides two modes to select the audio configuration, Fixed and automatic - Follow radio mode.

TIP: If Router can read frequency and mode from your radio (Ports tab | Set) use Follow radio

mode. It will provide automatic selection of the appropriate audio configuration.

When Router is unable to read the operating mode from your radio (radio does not have computer control

port or does not report usable mode information), chose Fixed audio switching. There are several

optimized settings for each operating mode.

CW (AAA) – The audio configuration is not important for CW operation. This choice has been included to

maintain consistency with T/R keying (configured on the PTT/FSK tab) where it is important. CW

(AAA) assures quiet audio switching and minimizes relay clicking.

VOICE (ACmA) – The station microphone is connected to the radio mic jack. When the computer

generates PTT on the virtual port PTT channel, the sound card output is switched to radio mic jack.

This setting works with VOX or PTT button (foot switch) mode and allows playback of voice

messages from the computer. With this settings it is not possible to record voice messages in

application software.

VOICE (CmCmA) – The station microphone is connected to the sound card mic input except when the

foot switch or microphone PTT is pressed. When the microphone PTT or foot switch is pressed, the

microphone is connected to the radio. This setting allows use of VOX or manual PTT, allows

playback or recording of voice messages, and allows interrupting playback of a recorded message

by pressing the microphone PTT or foot switch. This setting is recommended for most VOICE use.

VOICE (CmCmCm) – The station microphone is always connected to the sound card mic input. This is the

same as above but when the foot switch or hand mic PTT is pressed, the microphone remains

connected to the sound card.

VOICE (CmBA) – Special setting for radios which use the rear panel audio input for DVK input during

voice operation (N1MM Logger with Orion or Orion II). Do not use with other software or radios.

SSTV (ACA) – Special setting for SSTV mode. Microphone is normally connected to the radio microphone

jack and allows VOX or foot switch VOICE operation. When an image is being sent from computer

sound card, the station mic is muted and drive applied to the transceiver mic input (Yaesu).

SSTV (ABA) – Special setting for SSTV mode. Microphone is normally connected to the radio microphone

jack and allows VOX or foot switch VOICE operation. When an image is being sent from computer

sound card output, drive is connected to the transceiver rear audio input (Kenwood, Ten-Tec,

Icom).

FSK, DIGITAL (BBB) – The station microphone is disconnected and the computer generated audio is

applied to the radio’s rear panel audio input. This setting is recommended for all digital modes

operation regardless of keying type (FSK or AFSK).

DIGITAL (CCC) – The station microphone is disconnected and the computer generated audio is transfered

to the radio front panel mic jack. This setting is recommended ONLY for radios which do not have

rear panel audio input for digital modes like K2.
