Printing QSL made easy!

Managing labels for QSL cards is generally a problem if the data entry software does not include this feature.
I use Logger32 and WinTest for my logging, and used DF3CB's BV software to manage labels. Although the latter was complicated to use, it worked well. More annoying, it is no longer maintained or available on the author's website.

I found it to be well-designed, easy to use, very fast and reliable, requiring no other software such as ADIF pre filtering.
The author is also responsive and takes user feedback into account.

Petit tuto pour programmer un Arduino Pro-mini en ICSP avec un programmateur USBASP 2.0

Dans certains cas, il peut être nécessaire de programmer un Arduino via le port ICSP.
Par exemple, si le microcontrôleur a été remplacé par un neuf, si par mégarde le bootloader a été corrompu ou effacé, si le programme injecté est corrompu et qu'il n'y a plus d'accès via le port USB ou le connecteur FTDI, si le logiciel est distribué au format HEX, si on n'a plus accès au microcontrôleur via le port USB, etc...
