    So you will be visiting the Transas stand at LBS as well then.[img]/forums/images/icons/laugh.gif[/img]

    The Software that Clive is recommending is obviously the one to go for.

    So I might just see you there.[img]/forums/images/icons/laugh.gif[/img]

    Cheers

    Alistair..

    Hi Nick. Yes my handheld works fine in the P315.

    How's your smoking? In a bid to get ours sorted out we have been tweaking the fuel flow. In fact it has gone so well that we have blown up one of the engines which is now out of the boat and sitting on the engineer's bench with a big hole in one of the cylinders!

    Don't you just love boats?

    My Garmin GPS12 works fine at 38000 feet, through double glazing, so I guess your's should work fine through your Corniche windscreen.

    Max speed on mine (so far) is 625mph - What's yours?

    The emitter is a device, about the size and thickness of a ping-
    pong paddle
    &gt; that focuses sound in a laser-like beam over distance without
    attenuation.
    &gt; Powered by less than one Watt, it utilizes the sums and differences
    of two
    &gt; ultrasound carrier frequencies (40 and 60kHz, respectively),
    discards the
    &gt; summing signal, and utilizes the difference signal (then, 0 -
    20kHz) over
    &gt; which the desired information (speech, music, natural sound, etc.)
    is
    &gt; transmitted at levels up to 90dBA.
    &gt;
    &gt; Because of the manner in which the signal is sent to the emitter
    element,
    &gt; the resultant signal is a highly focused beam with a spread of less
    than 10
    &gt; degrees that can be heard clearly, with no spill (unlike parabolic
    dishes,
    &gt; for instance), over large distances...as much as several hundred
    meters.
    &gt; Coupling in a non-linear manner to air (rather than producing
    cyclical
    &gt; linear waves as normal speakers do), sound energy does not diminish
    as the
    &gt; inverse square law would otherwise suggest. Frequency response in
    the
    &gt; largest sized unit will cover from about 250Hz to 20kHz (lower
    frequencies
    &gt; will not focus accurately).
    &gt;
    &gt; It is especially useful in the field when doing certain types of
    research
    &gt; where a focused output beam of sound (rather than a spread) is
    appropriate.
    &gt;
    now you know :-)

    Not meant to be using anything with an antenna inside a commercial airline!

    If I agreed with you we'd both be wrong.

    REF; Hoo and Questor.

    Do you both take your Gps onto planes when you go away?
    Are you allowed to use them?
    Or do you keep it out of site up your jumper or something?

    Bizzare...

    Keeping it up your jumper makes it difficult to see.

    No one has ever said anything to me about using it, except on one occasion when a member of the crew thought it was a mobile phone. Can't be very different to people using portable CD players / DVD players, and it is of course only a receiver, exactly like the one they have on the flight deck.

    I am no electronics expert, but i would have thought if you weren't allowed to use phone on board then the same would apply to GPS, Don't the both use satalites?

    Dunno.
