setting values into bitwise-defined variables
by Declan Rieb 17 Jun '25

17 Jun '25

I’m obviously playing with my mental blocks. I’m trying to change a byte-string in the bitwise-parsed data structure with non-ASCII bytes. Is there a valid, general way to put values into bitwise ‘u8’ array variables? I can’t even assign into a single u8. I’ve built a sort of toy, with the following definitions [and I’ve paraphrased from my actual program]: from chirp import bitwise M = “”” struct { u8 b; u8 ba[5]; } blarg[2]; “”” def __init__(self): self.mem = bitwise_parse(M, b'\xfb\x01\x02\x03\x04\x05’) print("self.mem: ",type(self.mem), self.mem) … Then self.mem seems to contain the correct data. self.mem: <class 'chirp.bitwise.structDataElement'> struct { blarg: 2:[struct { jb: 0xFB jba: 5:[0x01,0x02,0x03,0x04,0x05] } blarg (6 bytes at 0x0000) But If I then try to change values in the structure, viz: ... self.mem.b = 0x0c self.mem.ba = [0x61, 0x62, 0x63, 0x64, 0x65] … I get errors in bitwise, mostly self._mem.ba = [0xff, 0xfe, 0xfd, 0xfc, 0xfb] ^^^^^^ File "/Users/x/chirp/chirp/bitwise.py", line 820, in __setattr__ self.__dict__["_generators"][name].set_value(value) File "/Users/x/chirp/chirp/bitwise.py", line 365, in set_value self.__items[i].set_value(value[i]) File "/Users/x/chirp/chirp/bitwise.py", line 535, in set_value self._data[self._offset] = (int(value) & 0xFF) ~~~~~~~~~~^^^^^^^^^^^^^^ TypeError: 'bytes' object does not support item assignment ______ Declan Rieb WD5EQY wd5eqy(a)arrl.net

Radio read & write protection
by ascendr＠linuxmail.org 26 May '25

26 May '25

Is there a way to handle Radios that have implemented read and/or write protections? i.e. something along the line of conditionally prompting a user for input during the download or upload process.

How to Get Added to CHIRP Developer List?

Can I get added to the CHIRP Developer name list so the Security Risk warning in LoadTestModules won't be displayed?

Driver - Developer Mode?
by ftt＠smtcpa.com 29 Apr '25

29 Apr '25

Can a CHIRP driver easily tell if CHIRP is in developer mode? I'm working on a driver that will have a "sensitive" setting (one that all users probably should not have access to) and only want to expose that setting when CHIRP is in developer mode. It looks like if the developer class is imported there is a method developer.developer_mode() that may be what I'm looking for. Thx, Fred

list index out of range error
by Andreas Ott 16 Apr '25

16 Apr '25

This is on CHIRP next-20250404 on W10. I am trying to copy&paste in a single memory channel line 3 from another radio into an Alinco DR-735T file line 3. The Alinco file was created by "download from radio", the source of the copy happens to be UV-5R. It fails to populate the column values in the Alinco tab and the left channel number column is now red "!*3" with "list index out of range error". I did reduce my test to just one line of copy&paste, after the bulk load of ~100 channels failed. Most of them errored out the same way but some magically worked with no obvious indication to why it worked or not. I can provide screenshots, chirp files or CSV exports if needed. Please advise what I should try next or what other diag logs I can post here. -andreas K6OTT

CHIRP on Chrome Flex OS
by dtpoirot＠gmail.com 08 Apr '25

08 Apr '25

Howdy, It took about 3 1/2 minutes to download the required bits into the Chrome Flex OS 'developer' environment and then get CHIRP running. I can open my Explorer QRZ-1, read the radio, open RepeaterBook, copy a line from RepeaterBook into my QRZ-1 file, and write the new repeater into the QRZ-1. Is there any sort of official authentication of CHIRP onto a particular platform? The Chromebook developer platform seems sufficient and n00b-friendly. Best regards, Dan KJ5IZK

Question about the build schedule
by Chris Mildebrandt 01 Apr '25

01 Apr '25

Hi! On the download page <https://chirpmyradio.com/projects/chirp/wiki/Download> it says, "Any time we make a change to CHIRP, a build is created for it the next day". There were three commits <https://github.com/kk7ds/chirp/commits/master/> on March 29th but the latest build is from March 28th. Is there a problem with the build system, or does the build not happen after each change? Thanks! -Chris

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

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
