After quite a bit of debugging I think we nailed it. At the time I was adding support for the DJ-G7 radio, I was not aware of a flag that was used to hide memory channels in the main band. The main band only supports a subset of modes and frequencies on this radio. My original code used this flag improperly, such that a channel was never hidden from the main band regardless of its settings. This does not do any harm to the radio, but such a memory channel is useless in the main band due to hardware constraints.
More importantly, the original programming software by Alinco crashes when operating on a memory map pulled from a radio programmed with chirp if the flag is not used correctly. After some discussions with and advice from Emiel, I have completed a patch that adds proper support for this flag. The patch is attached. See #5275 for a more in-depth discussion of the issue.
Cool, thanks!
Can you submit this in proper mercurial patch format? The patchbot and commit hook require it.
