CHIRP

The weather frequencies are definitely not stored in that image, which is ... interesting. If you delete channel 50 in chirp and upload the result, does it reappear in the radio's memory?

I'm wondering if this variant has some weird custom firmware that (a) throws the used/empty bits out of whack and auto-fills weather channels or something. Do the weather channels show up in the OEM programming software (or do you know)?

Also, what is in channels 99-112?

I currently have channel 50 programmed as 146.52 MHz. If I read from the radio, then delete the data for channel 50 in CHIRP, and then write back to the radio, the channel programming remains unchanged (146.52 MHz). It does not revert back to being programmed with NOAA WX channel 1.

Channels 99-112 are currently unprogrammed.

Thanks for the details Ken. It looks like this differs more significantly from the base Anytone radio than the other clones. I'll have to dig back into it when I get back from a trip. I suspect that the memories are grouped in some way so that after a certain number, there is a block of data, and then the rest of the memories continue, which would explain why it gets out of sync after a certain point.

Thanks for the support of this radio; I just tried to program two and find that I can only get channels 1-59 to "stick".

Happy to loan a radio if it helps.
