    Usually those are the band, AM or FM, but AM is 00 00 00 00, and FM is 01 00 00 00.  So maybe it’s HD sub channel?

    Maybe sub channel 1 is 02 00 00 00, 2 is 03 00 00 00, and sub channel 4 is 04 00 00 00.  That seems to make the most sense to me.

    The 08 00 00 00 I’m not sure of though.

    Edit, it looks like the 08 00 00 00 maybe a length of the incoming data.

    I think you are right.. Band AM =00, FM=01, HD1=02, HD2=03,HD3=04

    It’s interesting right?  Once you know how the protocol is laid out it’s not that difficult to understand.  But at first it just looks like a mess.

    I think I need more data regarding HD sub channels.  I only have two samples of HD Subchannel count

    A4 8 5 2 2 0 0 0 0 0 B5 (HD sub channel count)
    A4 8 5 2 2 0 7 0 0 0 BC (HD sub channel count)

    The only difference is 0 vs 7.  There must be more, as there isn’t 7 channels is there?  Maybe 0 = 0, but 7 = 3? I don’t know.

    Here you go. I moved to another part of the house and picked up a bunch more HD

     

    the HD-Seek was auto seeking for HD only stations.. I hope these help

    Oh excellent.  I’ll look at those later tonight.

    Do you know how many sub channels each station has?  The commands are showing 0, 3 and 7.  I don’t exactly know how to map that…

    Specifically 80.7, 90.1 and 91.5

    I ninja edited while you were replying.  Can you get the count for these three, 80.7, 90.1 and 91.5

    91.5 has hd1 and hd2 only

     

    80.7 too low

     

    90.1 only one with 3

    Excellent, what about 90.3, 91.9, 92.3, 92.5 and 101.1.

    It looks like 90.3, 91.9 and 92.5 all have the same number of subchannels as well as 91.5, 92.3 and 101.1

    I pushed a build tonight.  If you get a chance to try it out some of the HD stuff should (hopefully) work.  You can’t switch TO the HD sub channels yet, but the main station I’m hoping will show the correct data (HD1 instead of FM, song title, etc…)
