Description

I managed to program a FTM-350AR using Chirp, a USB serial adaptor (tried with my laptop's built-in RS-232, but it didn't like the non-standard baud rate) and a homebrew adaptor made many moons ago, however I note the new channels cannot be selected with the up/down buttons or the dial, I have to punch in the channel number directly.

Having a look at the memory browser, I don't see anything obvious, but clearly there's a "bitmap" here that tells the radio which channels are valid or not. The FT5DR had something similar in its little memory dump files.

I've uploaded the dump generated by Chirp -- now I'm not sure what parts of this file are Chirp headers, and what parts are Yaesu raw memory map: clearly it's not just a raw dump because Chirp can identify the radio from the .img file handed to it. hexdump -C doesn't show anything obvious, but maybe I need to make a change to a memory channel, then download an image again and diff the two to figure out where this extra bitmap is.
