Hello team,

My Kenwood TH-D72 is giving me a hard time.
What I did:
Factory reset on handheld, all channels empty.
Imported a CSV file which works great on other radios like Icom ID-51, Yaesu FT-60R; using CHiRP 0.4.1.
I am aware that this radio does not accept NFM.
Radio shows all channel names fine after upload, repeater offset seems to be correct, no apparent issue in spreadsheet.
However the radio won't transmit on any 2m frequency. 70cm works fine!

Maybe I'm overlooking something?

CSV andf IMG files are attached.

Thanks and 73,
Bernhard AE6YN

Use the live mode driver.

That did indeed help with my problem, however only after another full reset of the handheld. Thanks!
Clone mode seems to screw up the memory in it somehow, and trying now in live mode to import a CSV results in CHiRP hanging. A reset cured that.

I'd prefer to have clone mode working, because it's about 4 times as fast, and an image can be saved on disk. Makes cloning easier.

I have this issue as well, but clone image mode seems to work fine in Linux, so I believe this is a Windows-only problem?

I am also experiencing this issue in Linux (Linux Mint 17.3 Cinnamon 64-bit). Tried with version 0.40 from ubuntu-hams-updates PPA, and also with the latest daily tarball.

Same for me using macOS Sierra.

On the TH-D72A, I noticed that menu item 130 (VFO Prog) is completely blank with 2m memory channels, whereas it lists a frequency range for 70cm memory channels.
