Hello Jón,

You live in a Country which most likely is not as lawless as this one.
Is not as crowded.
We have laws, more than you want to think about.
But this RFI stuff is not enforced unless it interferes with
important stuff.

Back East I saw all kinds of FCC trucks loaded with
antennas but not out west here,
West of the Mississippi.

I swear, if all our laws were enforced there would be
civil war here.

Only major laws are actively enforced
and the tiny ones are saved for the
discretion of the officials.

They can use the tiny laws to make any person
they wants life to be hell on earth.
while leaving everyone else do what they want.

But, enough,

I will live with my problem,

I see a heavy vehicle pass by some times on my
chart just before the blackout of data.

If the software could reset itself 100 % after a blackout
The problem is pretty much solved.

I get an audio alarm for awhile then
have to reset it myself.

But this is not common at the moment.

I just made a change to the receiver putting it
on a pole,
above  metal awnings, will see how this
works.
Should give me a stronger signal.

Thanks for the replies.

Regards,
geoff

Hi,

I have never had a GPS signal jammed because of some other transmitters
that are being used close to my GPS antenna.

Regards,
Jón Frímann.
