Hi All,

GPS
I found that the two GPS antenna I have here
have thermal problems.
If I put the antenna outside the window (10 C degrees)
it become inoperative in 15 second.
If i keep it indoor, 20 degress, it is ok even if it pick only 1 or 2
satellites
per time...
When it is fauly, it is overcurrent on the WinOncore software.
The impedance become very low.
Anyone experienced this problem?

------

EDA
I obtained a PRS-4 Scintrex EDA station.
I have any software for it, only a small owner's manual.
It seems that the station needs a firmware to be uploaded inside.
It uses an hitachi processor and a 12 bit a/d converter with a double
dynamic
amplifier, low/high gain and samples both the signals and choose the low
gain
signal if high gain is clipped.
Does anyone know where download something about it?

Thanks
Mauro
