I’ve recently introduced a Raspberry PI 4 as main remote RTX controller for my Kenwood TS-590s.
This allows me to control the Kenwood TS-590S from the iMac simultaneously with several applications, including RUMLOG, FLDIGI, WSJT-X.
The issue
Could not control simultaneously my transceiver directly from two or more applications. Additionally remote connection from the internet requires a PC always turned on or at least the possibilty to power on with wake-on-lan
Cause
The usage of the USB Port is exclusive
Workaround
An alternative solution is to run the FLRIG on the iMac, and connect the applications to the local loopback 127.0.0.1.
I’m using RUMLOG by DL2RUM as main logging program both as main logging and for contest logging as well. FLDIGI for common digital modes and WSJT-X for weak signals digital modes.
What do you need
On the MAC you need to reconfigure the programs, in order to use FLRIG as Radio. Basically FLRG acts as a gateway to your radio.
Rumlog configuration
FLDIGI Configuration
WSJT-X Configuration
On the Raspberry you need to configure the connection with the USB to Serial cable connected to the RS-232 port of the TS-590S.
If you have issues on selecting the USB Port or you have multiple one, check the status of the USB connections with lsusb command
