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 […]

Allen’s Antenna Farm

The year started with major work on my antennas. Sourced a TET-Emtron TE-46 and it arrived November 2021.

Also had to fix the faulty 160M loop as well as paint and reseal roof lines. […]

Will boot from the SD card as want separate data partition. Booting from SSD is not the issue. With a 4 and latest OS it is a case of selecting […]

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 […]

more Raspberry Pi’s

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 […]
