[chirp_devel] Yaesu FT2D and "preset channels" question

[NNN Wx]

I’ve heard nothing else about this problem from the list, so I really hope you’ve something to help in your notes!

It’s clear that the UI for banks will need to be changed and/or augmented, and that part of the code is exceptionally opaque to me ATM.

Had you any ideas for even displaying the presets in the bank map? I’m thinking that the “channels” column on the left get augmented with, say “WX #0”… “WX #11”… “IVHF #0” … “SW #0” … probably only as needed, with the same types of bank checkboxes on the right across the screen. The FT2D radio allows the presets to be interspersed with the memory entries and not necessarily collocated at the end of the bank, so the chirp memory model for the FT2D is already more restrictive than the radio (not necessarily bad, but that’s how we got into this mess in the first place: something doable with the radio breaks chirp.)

Unfortunately for the Yaesu FT2D and maybe the FT1D, the actual preset frequencies don’t seem to reside in programmable memory and thus are not in the radio image that chirp uses. Right now it seems one would have to transcribe the information for “preset channels” from the printed documentation (and heaven help chirpers if the manufacturer changes those listings somehow. chirp would then have to support “stepping” versions of the radio.) I can imagine that “immutable memory” could hold these presets but I don’t see any radios with such extensive data in that poorly-described memory store. I could imagine that the flag bits would just cause chirp and the UI to point to entries in “immutable memory” instead of the memory channels.
