Thanks for the quick replay Basil.
Machine has been on for over 24 hours...gps antenna in same position that previously allowed to to receive all the satellites. Receiving no sats. I am now going to attempt a third antenna.
Doing the Sensors command I get the following...
pi@draws:~/bin $ sensors
Adapter: ISA adapter
Adapter: bcm2835 I2C adapter
+12V: +13.66 V
in5: +2.52 V
User ADC 1: +0.00 V
User ADC 2: +0.00 V
What is in5: and is that a good number behind it?
