In car APRS map install almost complete

I have fitted the tablet mount in the car, unfortunately by using self-tapping screws into a piece of trim panel on the passenger side, and have tested to find the best position for the tablet so it does not interfere with the operation of the controls, it does block access to the stereo at the moment however this is a minor inconvenience.

The wiring has tested out in a temporary location and RF from the radio does not appear to interfere with the operation of the USB port thus allowing the mobile phone to remain tethered to the tablet over USB, the last job to do is tidy up the cabling by means of cable ties, keeping the radio cable away from anything else of course, the USB cable for the phone will run out loose from the hub as it will be reused in the charger as well for when the tablet is not in the car (for instance when I am at work and I require to charge the phone, the USB hub cannot deliver enough current for a fast charge), the hub was not powered externally during the mount install tests, the Bluetooth GPS unit, which got a lock relatively quickly, was though I suspect the connector does not quite fit the socket on the unit which results in poor to intermittent connection.

Otherwise everything is working, the tablet is displaying whatever the radio receives, the position from GPS and anything on the APRS-IS that is out of radio range, so all set for the off to Blackpool in April

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
