Keying a Linear Amplifier

Pin 8 on ACC-1 will provide an open
collector output for keying a linear amplifier.
The Argonaut VI provides a 17 ms closure
delay before RF is supplied to the linear amp.
Refer to Figure 3-2 for wiring to this
connector. Remember to use shielded cable
for making this connection. The amp key line
is NOT a relay similar to those found on
many older transceivers.
switch rated for a maximum of 24 volts and
250 mA from the key line of your amplifier.
Many older amplifiers using an AC relay or
relay voltages exceeding the limits of the
Argonaut VI must use an amplifier interface
relay such as the model 318 sold through the
Ten-Tec company. When using the Ten-Tec
model 418 solid state linear (sold separately)
the proper interface cable is provided with the
amplifier for both keying and band changing
the 418.

"Digital Mode Operation" for directions on
how to set up the the line input for digital
mode operation.
The 712 USB Soundcard Interface should
only be connected to the Argonaut VI when
the setup is intended to be used for Digital
modes via the PC. Remember, the USB
Soundcard, when plugged in, becomes the
sound card that all windows sounds and video
sounds will go through. Meaning, when the
712 detects audio from the PC, e.g. a
Windows DING, it will put the Argonaut VI
into transmit.
