In the latest firmware (0.92) I have implemented geofencing that will avoid transmission when a Pico transmitter and it's balloon is over the UK, Yemen or North Korea.
I have had a few people ask me about it but have not had time do anything in that area until a couple of weeks ago when Matt Downs - 2E1GYP from Essex in the UK provided me with a working proof of concept C code and the Maidenhead Grids to use. This made the coding a whole lot easier and I have now been able to include it in to my WSPR transmitter firmware.
The change is not visible for the user in any way and there are no setting, it is just hidden in the firmware.
It is only in effect on my Pico transmitters.
Now when a Pico transmitter finds itself in one of the grids inside the geofence it will hold off on transmissions until it is outside again.
There is one exception to this rule and that is if a user has a pico running inside the geofence they can still do test transmissions on the ground with a pico as long as it is connected to a computer and the PC software is communication with the Pico over a serial port.
Here is a couple images that shows the areas of no transmission.

Do you know which libraries and dependencies i need to update and upload the firmware for my WSPR Pico Unit. I can remove the UK Maidenhead grids in the code but compile/verify fails everytime even trying to unmodded firmware Regards Richard Fairman
can you direct me to the correct open source file for the wspr pico transmitter thanks
Thanks I'm not a programmer. Is this easy to do my Maidenhead locator is io75rx I've just ordered a wspr pic from you
Can geo fencing be temp disabled or adjusted. i want to test a pico unit in UK on solar without having to connect to usb The unit will always be at zero altitude during test so will not contravene UK ofcom regs Can geo fencing be disabled at low or zero altitudes i want to test the unit at the top of my garden during a 24 hour period with daylight and darkness
Thank you Harry. This will help. It's good to see the LU7AA sight is working again, even if it is slow. I like the fact that I can forward a link to non-ham friends who can track my balloon without having to input information. The VK7JJ site is faster, but I'm reluctant to give that site to non-hams who would get lost before they ever see a map.
I plan to launch again tomorrow or next weekend. I have a few ideas about what went wrong last week. This time, we might succeed...
