Setting up gpredict on linux for use with a Icom IC-9700 radio.
(testing)
settings on the IC-9700:
CI-V USB Port: Unlink from[REMOTE]
CI-V USB Baud Rate: auto
CI-V USB Echo Back: OFF
CI-V DATA Baud Rate: 19200
CI-V DATA Echo Back: OFF
CI-V Address: A2h
CI-V Transceive: ON
When the radio is connected to the PC you should see:
$ lsmod |grep cp
cp210x 24576 << is the kernel module and memory size, if compiled into the kernel you won't see the module but may still work, try below.
$ lsusb
Bus 001 Device 079: ID 08bb:2901 Texas Instruments PCM2901 Audio Codec
Bus 001 Device 078: ID 10c4:ea60 Silicon Labs CP210x UART Bridge
Bus 001 Device 077: ID 10c4:ea60 Silicon Labs CP210x UART Bridge
Bus 001 Device 076: ID 0451:2046 Texas Instruments, Inc. TUSB2046 Hub
The radio control port is the usually first port:
$ ls /dev/ttyU*
/dev/ttyUSB0 /dev/ttyUSB1
Setting up the daemon from hamlib:
~/Hamlib/Hamlib/tests $ ./rigctld -m 3081 -r /dev/ttyUSB0 --civaddr \0xA2
main: #1 vfo_mode=0
Recommend using --vfo switch for rigctld if client supports it
rigctl and netrigctl will automatically detect vfo mode
Be aware of the hamlib 4.1 parameter -x/--uplink switch for GPredict. Will avoid reading freq from the uplink.
This will help for a better handling when sweeping over a linear satellite transponder.
The daemon should be running in the background now, "./" is only needed for local execution and testing, if installed from a package:
$ rigctld -m 3081 -r /dev/ttyUSB0 --civaddr \0xA2
Or you can initiate with "systemd/rc-init" once testing is stable.
Radio config in Gpredict:
Edit -> Preferences -> Interfaces -> Add New
Name: IC-9700
Host: localhost
Port: 4532
Radio Type:Duplex TRX
PTT status: None
VFO Up/Down: Main Down Sub Up
LO Down: 0
LO Up: 0
Signalling: unchecked
in Radiocontrol widget:
Settings:
1. Device: IC-9700
2. Device: None
Cycle: 1000
Note on Cycle:
Faster is possible due to USB use but the Interrupt on the Waterfall and Radio itself may be more noticeable.
Currently working well on firmware revision 1.23
(to be enhanced...)
