Yes

Description

(Describe what you were doing)
Trying to set a channel to AM mode for air band

(Describe what you expected to happen)
AM mode to be selectable, at least if frequency is in air band

(Describe what actually happened instead)
Only FM and NFM are available modes no matter the frequency

(Has this ever worked before? New radio? Does it work with OEM software?)
No. Yes. OEM software only supports picking wide or narrow, does not seem to support any other mode selection.

Note: it still works. Air band channels are switched to AM mode on the radio once uploaded. It just makes pasting in channel lists from other places annoying because of the "unsupported mode" warnings on channels specified to be AM mode. And makes exporting channel lists from this radio confusing because every channel is listed as FM or NFM mode.

Just like you don't choose AM when programming from the radio, when you program an 'air band' frequency, the radios automatically sets itself to AM. The Mode value in CHIRP is ignored.

Yep, what Jim said is right, although I know it's also annoying to not be able to import/paste AM channels when they're in the proper range.

I've got a pattern for these (dumb) radios that have this annoying behavior that I can apply to the 470X. I'll do that in the next day or so and have something for you to try.

Thanks. I know it works, just hoping to fix the annoyance since I've been copying channel lists between radios that do and don't support it.

I was actually checking out the code to see if I could figure out a similar pattern. I started working on one that I borrowed from the TD-H3 (since I know that radio does have the option in Chirp), so I'll be interested to see the change you come up with.
