Problem: Transceiver power shuts off
while transmitting
The Argonaut VI is equipped with a silicon-
controlled rectifier that opens if the PA
current draw exceeds an instantaneous power
of approximately 30 amps. This will shut off
power to the transceiver. Excessive current
draw can indicate a problem with excessive
SWR due to antenna or feedline problems.
Power to the radio can be restored by cycling
the power switch and off or the 13.8 Vdc
source on and off.
Problem: No transmit, receive OK.
Are you trying to transmit outside of the Ham
Band?
Is the gain setting correct for the microphone
input or ACC 1 jack as appropriate?
Is the POWER control turned all the way
down? Press PWR and check.
If no transmit in digital modes, are you sure a
PTT signal is being sent from your TNC or
computer to the appropriate jack on the
Argonaut VI?
Are the internal fans running at maximum? If
so, then this could indicate the Argonaut VI
has a final amplifier temperature of 70
degrees C or higher. In this condition, the
radio will stop transmitting until the final
amplifier temperature is back down to a
reasonable level.
Problem: Get a “PORT in use” when
trying to run logging or computer control
program or when trying to update the
firmware.
Have you confirmed the proper port number
in Device Manager? Remember that when
connecting the USB cable to the USB port on
the computer, every time you connect the
USB cable into a different USB port on the
computer, it will have a different COM port
number. You can verify this in Device
Manager. It is possible that the USB port was
used previously and for some reason
Windows has not released it for use. In this
instance, disconnect the USB cable at either
the computer end or the Argonaut VI end, exit
the program you are trying to use, wait a few
seconds, then reinstall the cable and then re-
start the program you were trying to use.
