    ** An aerial is always a good idea for a radio tuner.

    Describe what AM aerial you have now and what is wrong with your reception
    and if it is the same with all stations.

    Also - how far are you from the transmitters ?

  3. Careful Robby,

    Philthy Phil, (a.k.a. Toaster Boi) - the all round crackpot and net-stalker
    is making an attempt to work out where you live. Any assumption that he is
    trying to be helpful is a smokescreen. if you don't believe me, then take a
    look over in aus.hi-fi and see for yourself.

    BTW: Most hi-fi tuners have a pretty useless loopstick antenna which is
    part of the front-end tuning for the AM section. Unless you are a long way
    from the transmitters you should be getting reasonable AM reception. The
    orientation of the loopstick antenna will determine it's pick up sensitivity
    to a particular station. The user manual for your receiver should make
    mention of this. A length of wire connected to the AM antenna input should
    improve your reception.

    Cheers,
    Alan

  10. Dank, free agent aint so free any more.. Ctrl K only works if you pay.
    I guess a few dollars is well worth it.
     
  11. Short and selective memory is what you have knuckle head. Forgotten about
    your Marist connection already, or is it they have forgotten about you?
     
  12. **What specific problems do you have?

    You should know that for decades (since the widespread introduction of FM)
    most manufacturers have paid little attention to the design of the AM stages
    in their receivers. Using different antennae is kinda like shifting a deck
    chair on the Titanic. If AM is important to you, seek out an Audiosound
    (Australian made) or Allen Wright tuner. Both are capable of exceptional
    results. If you want to work within a budget and have some technical skills,
    seek out an Australian made car radio (AWA made many) from the 1960s. These
    are also capable of exceptional performance. Off to the wreckers and find an
    FC Holden.

    ** Diode AM detectors can produce very low distortion.

    Two tricks are used:

    1. Apply a small voltage to a germanium diode to bias it on slightly.

    2. Use a fairly large IF signal voltage to the diode ( maybe 10 volts rms)
    so diode non-linearity becomes insignificant.

    Oh, for goodness sake! We've got the message (somehow) that you don't like
    each other.. Now we wish you'd form a direct liaison to exchange insults, and
    leave the newsgroup alone to discuss ELECTRONICS.
