AM Antennas????

    Hello,

    I have a Pioneer VSX 405 receiver in my home that I will be needing to start
    using for AM reception.

    The station is local and comes in fine on the Sony portable and in all areas
    for miles around in my car... but the Pioneer just doesn't want to grab
    it... or much of any AM stations.

    I have the table-top loop job that came with it, but it has been jammed down
    in a mess of wires and such for a few years and I'm wondering if it may be
    broken? Can I do a continuity check? Should it show any resistance or any
    continuity at all?

    Is there another AM antenna that would work better? I also like to listen to
    far-away FM and have a Radio Shack FM antenna on a pole outside... is there
    an attachment I could use for AM? How about a small CB antenna or such? This
    AM station comes in terrific everywhere around... except on this Pioneer :-(


    Any suggestions on excellent AM listening?




    Thanks so much for any input.

  2. Have you tried a length of wire connected to the AM antenna terminals? (Try
    both terminals)

    the AM section on this receiver MIGHT be broken.

    i find in most cases that a a couple feet of wire attached to the AM
    antenna terminal of a receiver is sufficient to receive strong local
    stations.

    i get called on to check radio reception on a regular basis. my usual method
    is to take a battery powered portable radio and place it near the radio in
    question. if the station comes in fine i go AHA! and proceed from there. if
    not i have to explain to the client what his or her options are.

    your existing AM loop antenna should measure 1 ohm or less (probably near 0
    ohms). make sure the wires are bare and not coated with and insulating
    varnish. make sure when you attach them that they are in good electrical
    contact with the terminals.

    I've had a similar problem with AM reception. However this was on a unit in my shed
    with an iron roof.
    Solved the problem by connecting a length of wire from AM terminal to the iron
    roof... it now receives channels that I didn't even know existed!

    Yikes! I hope you don't get a lighting hit.
