Interesting.
The old decoder shows

dfm06ptu detects only DFM06 and DFM09.
DFM09 has the ID in channel A, the last channel. Newer models have more channels, so the ID in the last channel could be in channel C or D. dfm09mod is more flexible and tries to detect the ID in the last channel. In all the samples I tested, the channel before the last one was always zero, that was easier to detect, since a decode in poor conditions could show higher max-channel numbers, if decoding went wrong, or lower, if the highest channel could not be decoded at all. So maybe if no zero-channel is detected, an alternative approach should be taken to detect the highest channel number without errors.
Will take a look.
Also the second nibble next to the channel number seems to be "C" for the ID-channel, maybe that's a good alternative. (for DFM09 and higher, not sure about pilotsonde) my comment here:
projecthorus/radiosonde_auto_rx#109 (comment)
DFM-09 has the ID in "channel A". Second nibble seems to be C for A, C, D.
UPDATE:
quick fix (513): 0xsCaaaab (i.e. 2nd_nibble==0xC)
no max-ch reset (yet), if another/second dfm is encountered (would require more book-keeping).

Pit[m] has also mentioned that it appears to be showing up as DF63890B on radiosondy.info, but who knows what dxlAPRS is doing...
ID9:17008907 = 0x103890B
They take the last 5 nibbles, DF6:3890B.
But they have different methods, and DF6 or DF9 is sometimes misleading/confusing:

Simple enough! Have changed my code to match.
I've also merged in your dfm09mod changes (and confirmed they work fine with all the samples I have).
Thanks for the fixes!
