CHIRP

Those frequencies don't look like anything that would likely assigned by any agencies. Normal step compatible frequencies would be:

464.1875 (diff -500 Hz)
458.6625 (diff -500 Hz)
407.1125 (diff -800 Hz)
407.1375 (diff -800 Hz)
408.0125 (diff -800 Hz)
464.0890 (diff +500 Hz)
469.2625 (diff -900 Hz)

I would be interested in knowing where/how you came up with those frequencies?

At least I find it interesting to read that the UV-17Pro driver reads the UV-21Pro.

I have a Chinese frequency sniffer. https://a.co/d/fBmSGpW

it is a close, but not exact thing, lol.

The issue is that chirp legacy doesn't complain about the channels, just programs them. When I look at the frequency in the older model radios, I see what appears to be exactly what I have input in chirp, just like in the posted picture, albeit rounded to 3 decimals. ie. 464.188. In the UV-21 I can punch in 464.188, and it just puts it at 464.18875. I can also punch in 464.18750. Chirp next however lets me punch in the frequencies you posted, which is probably more accurately the frequency of the company's channels, but not 464.18875. But the frequencies I am using are working on the older radios when I use them.

thanks to everyone who maintains this software though, just so I am clear, you guys rock.

as much as I would like to take credit, I googled somewhere it is the same software.
