Description

Something feels off with the config on this radio, it is failing to right if I adjust perfectly normal values, and then other odd stuff I cannot fully reproduce is happening as well, like the TSQL only transmitting CTCSS but listening as if no CTCSS is applied. I am even getting wrrite errors if I modify it enough. Both the stock ebay config and the one I have loaded are in place below.

This was programmed using the 762G driver

Some of the front panel key mappings are wrong,
first I will list the chirp value then an = which is the actual button on the radio
A=MON
D/A = 〇
triangle up = A
triangle down = ⬤
MON = doesn't exist?

see https://www.manualslib.com/manual/1310818/Kenwood-Tk-760g-Series.html?page=11#manual for an image of the front panel.

I have done more digging with the OEM firmware on this radio, there is a setting missing from CHIRP called "off hook decode" which makes it so only CTCSS can break squelch.

I would suggest adding a tooltip once this option is added so people can understand its purpose.

I will include two chirp images, one with off hook disabled, and one with it enabled.

I have resolved all issues at this point, other than the one unexplained crash, which I will call a one-off issue and not worth tracing.

  • File tk760g.py tk760g.py added
  • Subject changed from Kenwood TK762HG - Programming inconsistenty to Kenwood TK762HG Missing setting

Most people familiar with commercial radios, especially kenwoods will know what "Off-hook decode" means. However, happy to add a tooltip of course.

Attached is a module you can try with LoadingTestModules that adds the new knob under basic settings. Please test and report and I'll push this fix for this week's build.

Excellent A/B image samples by the way. Thanks!

I received an error when doing my first write attempt on block 50. This was with me disabling the off hook option. It appears to have applied, will perform additional testing to see if I can repro the issue.

Again I am seeing the block 50 error when writing re-enabling the mentioned setting. I have not messed with any additional settings e.g. front panel to kep my test case as simple as possible.

I think you're asserting that flipping the bit for the hook setting has some impact on your ability to clone the image back to the radio, right? I think that's highly unlikely as that's not generally how these radios work. I could literally upload total garbage and only after it is complete would the radio determine it was unacceptable and report "NO PROGRAM" or whatever that model's indication is.

If I take either one of your sample A/B images and use CHIRP to flip the bit, the image becomes an identical bit-for-bit copy of the complementary image (barring the chirp metadata footer that is not uploaded to the radio). I suspect that what you're actually seeing is just the general instability of the cloning routines for this radio (which have always been very bad, have been rewritten a few times, and which are better but not perfect now).

If you can reproduce this multiple times with a lot of certainty, then I'd be more willing to entertain that it is related. Like, download from the radio, upload the unchanged image five times in a row with no failures, then flip that knob and fail to upload five times in a row after that.
