Thanks for the reply Tony. TShark version is 2.6.8. Yes, I have to remove the space between the dash and the i in the start_trace command. I also have to 'sudo modprobe usbmon' and 'touch cap.pcap' before starting. (time goes by) I was trying to capture a read from the radio. If I run tidy on this data to stdout I can see where the fault takes place in the tsv but I don't know why. I had success sniffing a write to the radio and I now have a nice radiotrace file. What is the next step? I will make some subtle changes and figure out how the memories are laid out. Rich

I really like Chirp and I thought I might try to help out with adding a
new old radio.
I recently bought a used Icom IC-V8 and I have a programming cable. Programming software runs fine under Wine. I followed the directions on the Linux USB sniffing page. I can capture fine and I end up with a cap.pcap file that is about 1 MB
in size. Did you have to update the start_trace.sh script and remove the space between the dash and the i? start_trace.sh didnt work for me until I did that tshark - i usbmon$bus -w cap.pcap vs tshark -i usbmon$bus -w cap.pcap
I can then run the first 2 commands in the clean script and end up with
the capdev and capdev.tsv files.
But when I try to run the tsv file through tidy, I get a segmentation
fault but it does create an empty radiotrace. Just ensuring that you are compiling tidy.c using the info at the wiki: https://chirp.danplanet.com/projects/chirp/wiki/DevelopersUSB_Sniffing_in_Li...
Any ideas?
This doesn't help but I can reliably crash tidy with the non-tsv file so, maybe open up the TSV file in a text editor and ensure it "looks good"?
The c file is written with a pretty high expectation that the TSV file is perfect so I suspect the TSV file formatting.
What version of tshark are you using (tshark --version from a command line should be sufficient)
Thanks, Rich Gordon k0eb
