Hi,
When acquiring a fix with the internal receiver, it is a good idea to
hold the onhand away from your body.
Remember when testing the internal vs the external, the internal is
surrounded by the electronics of the device and is therefor susceptible.
HIMS has done a remarkable job with the sensitivity of the internal
receivers for the QX and onhand.
Also keep in mind, your onhand has not had a position fix where your
holux has. Sometimes it could take up to 10 minutes to acquire the
first fix with internal receivers.
