During several years of device development at my [[http://microsat.com.pl|Microsat]] company I realised that the weakest part of my products was a closed-source software. Writing every part of code by yourself and from the scratch, is complicated and very time-consuming. Also managing the source code and working on firmware updates are much harder now when I have two children consuming most of my CPU time, while my mind is still single-core :). | During several years of device development at my [[http://microsat.com.pl|Microsat]] company I realised that the weakest part of my products was a closed-source software.

The RF part is similar to this known from my APRS Voyager, but this time it is improved and covers the whole 136-174 MHz and thus it can be used for a lot more tasks than APRS. |
