APRS map display revisited

As you may be aware, in an earlier post in February of this year, I discussed displaying APRS objects received by a radio on a map, in this case the radio was my Yaesu FTM-400XDE and the tablet was my Huawei MediaPad T1 4G, unfortunately earlier this week I lost the tablet on my now cycle commute to work, leaving me with only my old tablet, a Tesco hudl (the first one not the hudl 2), which isn't really up to running a lot these days hence why I got the MediaPad in the first place, so I'd not really want to use that as a replacement, also as it lacks mobile data connectivity it is not suited and my 3 UMTS stick would not work with it without significant modification to the firmware to include drivers for it.

So I need a new tablet and decided my next tablet will be a Windows tablet, specifically the Linx 1010 as it has 2 dedicated USB ports and can be charged with USB devices plugged in, and as it is a Windows tablet I can use APRSISCE32, this has of course been done with a Windows tablet, a video on this topic, though it seems to have focus on the USA, had been made 2 years ago by Dallas Clements K7DCC.

The tablet used by K7DCC was a Windows 8.1 tablet, the Linx 1010 is a Windows 10 tablet, though as far as I can tell APRSISCE32 runs on Windows 10, though of course I need to reconfigure my laptop installation of this very same program to my new callsign (which requires authorisation to APRS-IS as I have not done this since I got my Intermediate).

Of course my car has limited room in which to add things, the tablet would need to be positioned in a location where it would not impede my operation of the car, it would need to be placed so as not to distract my attention, I can reach it while I am parked up, and I am still able to apply the handbrake and change gear when needed, also it needs to be in reach of the charger as it won't last a long journey when not on charge.

Mobile Internet is not available built into the Linx 1010, as I can buy myself out of my tablet contract between now and December (it will be cheaper as each bill between now and then is paid), I should be able to get hold of a 4G WiFi adaptor from EE, the cost to me should be similar than what I pay now for the tablet that I lost.

The Linx 1010 does not appear to have GPS installed, and it may not get that information direct from the radio in APRSISCE32, so I'd need an external GPS device, I have a Bluetooth GPS device that I bought some years ago for a Windows Mobile device to use with TomTom Navigator, I plan to test the unit with my laptop first to ensure it works as I hope it does (using APRSISCE32 as I have this on my laptop as alluded to above).

Hopefully I can start work on this next month after my car gets through its MOT, though it may not happen until after the Hamfest, but we can see what happens.

Due to past abuse and the ongoing issues that left me little choice to reduce time on twitter and IRC I have taken the decision to keep comments disabled indefinitely, apologies for this
