4680.0. "Noisy A2000" by KAHUNA::SUMNER () Mon Apr 15 1991 15:26

    
    I have a problem with my A2000 audio on the right channel.  When I
    power up the system I have this annoying 5Khz whistle coming from
    the right channel.  I've switched the channels around on the monitor
    and the whistle follows.  I then hooked the 2000 outputs to my receiver
    and the whistle remained.  When I use the modem and call in to work
    the frequency about doubles, I can also here the data faintly when
    the characters print across the screen.  Has anybody had or heard
    of this problem before?  I know it could be Paula or the LF347 amp
    but, before I take it in and have the shop I bought it look at it (I'm
    not that confident in they're tech skills) I'd like to hear if this
    problem has occured with anybody else.  It could be a noisy buss
    but, I can't see how it would bleed over. Any help appreciated.
    
    Thanks,

    If I remember correctly there is some audio input on the serial
    connector if there is something on that pin it may cause your
    problem.
    
    I would try disconnecting the serial connector to see if this help.
    You could have some problem with the connector itself (DB25).

    That was it Hubert.  I disconnected my modem cable from the serial port
    and WALA ... no noise!
