28 HOW TO OPERATE IN DIGITAL MODES
Digital modes such as FT8, JT65 and PSK31 are implemented in third party programs that must run in
a computer separate from Maestro. The recommended configuration uses DAX and CAT on a PC to
connect the digital mode program to the FLEX-6000. This is accomplished in the same way that CAT
and DAX are used with SmartSDR for Windows, with the noted exception that SmartSDR and Maestro
perform the same basic functions and cannot be running simultaneously.
The DAX channel for audio output from the radio can be selected in Maestro in the Slice Receiver
Menu. This audio channel, the DAX TX Audio channel and a CAT port are generally required for each
band where the digital mode will be run. When using this method, Maestro may be used to tune the
radio, observe the spectrum for likely operating locations, etc., but the DAX and CAT software
communicate directly to the radio. Maestro is designed to operate in conjunction with a digital mode
program operating in this manner.
When running digital modes, the computer screen can be effectively extended by running the FLEX-
6000 transceiver with Maestro instead of with SmartSDR for Windows. The computer screen can be
dedicated to running the digital mode programs.
28.1 PTT OVERRIDE WHEN OPERATING DIGITAL MODES
When operating in a non DIGx mode, use of a hardware PTT such as the RCA PTT input on the back
panel will override the DAX channel input. This feature allows the user to override the DAX input
with a PTT switch connected directly to the radio, or to Maestro.
