1/doesn't really answer my question- are there any technical advancements that have been made to the actual radar box over recent years /technical specification changes to the hardware etc or are all the improvements down to the software.
"/when not linked to the internet will I see the reg on my screen or just the mode-s code.
You will see all the details for all the aircraft in your RadarBox database even when you are not connected to the Internet. RadarBox comes with an extensive database, so even if you have never connected it to the Internet, you will still get a significant number of aircraft with full details. When you are connected to the Internet, new aircraft that you pick up (those not already in the database) will be auto-populated with details if they are in the GAS online database used by the AirNav server. This means that when you run RadarBox off the Internet next time, these aircraft will also show their details as they are now in the RadarBox database.
This system is far superior to the competing product that comes with a completely empty database and no way of populating it even when you are connected to the internet, unless you use the 3rd party GAS Populate program.
I hope that this answers your question.
