Thank you for your response, Mark.
I am using the internal antenna and the switch is confirmed “int”
There is always clear access to the sky when I test after reading similar posts on this forum.
I am taking it out on a walk later today to see if it’ll make a difference though whilst testing in my front and back garden, there is little obstruction, if any to the sky.
The Pi only has the BerryGPS-GSM attached.
I am enabling assisted GPS through the tutorial on ozzmaker.
Many thanks again
