ARM Notebook

Recently acquired a PineBook Pro. This device is to replace my ageing (2013) Macbook Air. The Air is still adequate for the tasks however the battery is EOL and will turn off once below 40%. Replacing the battery is an option costing ~$100 with 12 month warranty. Ok, Apples new Airs are based on ARM processors but I have been […]

APRS supports real time information sharing between enabled assets, not just positioning packets and SMSGTE enhanced […]

APRS and rabbit warrens

Anyway that aside I was intrigued by references to “Ham Radio of Things (HRoT)”. The value is having a view as to local activity, not just positions of cars but […]

Whilst the config will depend on the devices role all are running the same base install. The Raspbian image for all models of Raspberry Pi is now based on Buster, the latest version of Debian Linux. Debian 10.6 was […]
