    While trying to hook-up a MCP ( a MicroKEYER from MicroHAM) to the
    TS2000, I discovered the MCP doesn't work while connected to the ACC2
    connector on the radio.
    I try to use the TS2000 with the MicroKEYER for RTTY-FSK.
    My problem is this : on the pins 3&4 (= AF output + GND to connect to
    the MCP for digital operations) is NO (audio)signal ! ,(only about
    100mV DC) , this for ALL modes (FSK,CW, LSB , USB , AM) EXCEPT for FM.
    In FM-mode there is on these pins a nice and proper audiosignal (!). (I
    assure you I measured the signal on these pins with a scope and
    listened with headphones.).
    In the radio's MENU (n°50) I adjusted the audio level for max. (9).
    It doesn't make any difference. I read carefully the manual, and I
    think all the radio settings are correct.
    This is very unclear for me , no audio for FSK/LSB where it is needed
    most, and nice audio in FM when this isn't needed.
    The solution I use momentary is using the speaker output of the radio
    for RTTY operations. A disadvantage is that I have to use the radio's
    main AF control to adjust the signal level in stead of the radio's
    menu 50.
    I really would like to use the ACC2-signal for RTTY-operations.
    Is there something wrong with my radio, or do I something wrong ? I
    would appreciate it very much if you could help me.
    These are my radio menu settings:
    FSK shift 170Hz
    (menu 38)
    FSK polarity :INVERSE (menu
    39) necessary with MicroKEYER
    FSK tone 2125Hz
    (menu 40)
    TNC Main and SUBband AF output : 9 (menu 50CD)
    External TNC :MAIN Band (menu
    50E)
