    Dear members,

    I recently posted the query below and I would like to thank all those who replied.

    If you are using the flock of birds motion analysis system in UK, we'd be

    Dear Dr Mootanah,
    I would be happy to chat. I've been using the device for about 10 years.

    We had a Flock system a few years ago in our labn and eventually sent
    it back, as we were unable to properly use it for several reasons:

    - We have a relatively small space in New York City, so the system
    was never far from a floor or wall with metal studs.

    - Beware the automatic gain control! We had an issue (at least with
    the extended range transmitter) where if the distance from the
    transmitter to the birds changed too greatly over time, the automatic
    gain control would kick in, and cause very large artifacts in the
    data we collected. This was not due to metal interference, as we
    could duplicate the situation in the middle of someone's lawn in his
    backyard. So, whatever test you're doing, try to make sure the
    distance from your birds to the transmitter stays constant.
