Hello PSN:

Many of you have this gps receiver to get good times on your graphs
and over time you should learn any problems.

I have found one Which I do not know how to beat.

There seems to be RFI related problems
where the in the presence of a high energy RF field
of some frequency the GPS signal or A/D board is being
jammed and the lock is lost and an alarm will sound.

This problem is not the fault of of the device
but simply related to the fact the unwanted RF signal
has penetrated the electronics.

Can anyone tell me if they have successfully won
the battle of when like a police car or fire truck
or other government car is outside in the neighborhood with a 25 watt
transmitter maybe 100ft away and using their radio ?

It wipes out my data and everything for a minute or so.

This mostly happens in the winter when the city
here grows three times its normal population.

Comments ?

or, grumbly in Arizona.
