Whenever I use Gpredict with my 847, I need to set the refresh rate to about 5 seconds (5,000 ms). Never understood why, but updating too often quickly ends up with a hang. This is on a Linux system with a real serial port (not USB). I'm using "rigctld -m 101 -r /dev/ttyS0 -t 4532 -v -s 57600" as the run string for the rig control process.
Good luck,

I have been troubleshooting CAT control problems of my 847 ahead of Field Day, and the oddest situation has come to light and wondered if anyone has seen this situation.
I used to run Gpredict on my Mac, and on a Linux netbook with the 847, and both worked fine. In testing the setup in portable operation over Memorial Day weekend (on one of the XA birds), CAT control stopped working with the Netbook. Flatly refused to work. Before I started transmitting, however it had been running all day prior to moving to the portable setup.
I moved to the Mac, and it too wasn't working. Puzzled, I tried a reset of the CPU in the radio. Nothing changed. Tried a different Prolific and FTDI USB adapter. Nothing.
The shack computer, a desktop, works fine both Linux and Ham Radio Deluxe under Windows 10, with all three USB adapters. I also dragged out an ancient Sony laptop with a real RS-232 port. That works. I made some test scripts on the desktop Linux machine to initiate CAT commands, they worked at all possible port speeds. Tried the scripts on the netbook and Mac, they do not work. Hamlib reports a communication error.
I also have a 5 year old i5 Windows machine, never ran HRD and that does not work either.
I am not sure if the radio is on its way out, or if there is just some strange incompatibility between the USB serial adapters, but the desktop box works very reliably where the others do not. And the last thing I want to do is drag that beast out to FD.
