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
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
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.
Any input welcome.
