Creating a driver for KG-805g
by Chris Mildebrandt 23 Mar '25

23 Mar '25

Hello, I'd love some help creating a driver for the Wouxun KG-805g radio ( https://chirpmyradio.com/issues/11214). I've performed captures of all the settings, they can be found here: https://github.com/mildebrandt/kg805g Looking at the trace files, I'm a little confused about the memory layout. I changed the R-CTC setting from "off" to "67.0" on channels 3, 4, and 13. Here are the differences: CH03: change is at the 89th position <570010405062254650622546ffffffff95ffffff5087254650872546ffffffff95ffffff5012264650122646ffffffff95ffffff5037264650372646ffffffff95ffffff <570010405062254650622546ffffffff95ffffff5087254650872546ffffffff95ffffff50122646501226469e02ffff95ffffff5037264650372646ffffffff95ffffff CH04: change is at the 121st position <570010405062254650622546ffffffff95ffffff5087254650872546ffffffff95ffffff5012264650122646ffffffff95ffffff5037264650372646ffffffff95ffffff <570010405062254650622546ffffffff95ffffff5087254650872546ffffffff95ffffff5012264650122646ffffffff95ffffff50372646503726469e02ffff95ffffff CH13: change is at the 25th position <5700d0405087764650877646ffffffff95cfffff5012774650127746ffffffff95cfffff0050254600502546ffffffff95ffffff0075254600752546ffffffff95ffffff <5700d04050877646508776469e02ffff95cfffff5012774650127746ffffffff95cfffff0050254600502546ffffffff95ffffff0075254600752546ffffffff95ffffff My uninformed thought would be that I'd see the bytes change in the same position for the same setting on each channel, but they seem to be all over the place. What does this mean for me trying to lay out the memory? Am I being fooled by the trace output...and it's being recorded out of sequence? I wouldn't think so since the ordering looks to be stable per channel. I'll describe my setup in case there's something weird there. I have an Intel Macbook Pro with Fedora Linux installed. In Fedora, I have a qemu Windows 10 machine that's running the Wouxun software. I'm running tshark on the Linux side to capture the USB traffic. Any pointers would be appreciated. I'm pretty far over my head, but hopefully I can help get this radio into chirp. :) Thanks! -Chris

Chirpc command line arguments
by Ron Mikulecky 13 Mar '25

Hi all, I'm working to add in a FT-2980R subclass to the FT-2900R/1900R, and wanted to also capture the memory map images for the radio. The only way I can see to do this is by using the chirpc commands, but I can't exactly tell what is going wrong or why it's not working. I am able to use the standard GUI with the modified driver file to download and upload configurations from the radio, but I can't get the command line to work. So my ultimate question: Is my syntax wrong? chirpc -r Yaesu_FT-2980R -s COM3 --mmap 2980test.img --download-mmap The README.chirpc file suggests that it should be chirpc -r Yaesu_FT-2980R --serial=COM3 --mmap=2980test.img --download-mmap but it didn't seem to make a difference for me. I get the "Failed to read header" error from _download(radio) in ft2900.py. Again, I don't get any such errors when running the GUI application, I can download and upload modified configs perfectly. My process is to hit enter on the command line, and quickly press the Set/MHz button to start the radio transmitting the image, similar to the GUI suggest process of clicking 'Ok' and then pressing Set/MHz. Thank you for any help, Ron NR0N
