A NAS is great for your backups of e.g. your valuable log data and so on, but you can't call them cheap nor can you do what you like with them.

If you sill have a usb hard-drive lying around or a Beaglebone Black that you bought to play with but without a destination you're halfway there already!

Because here's a fantastic home-brew project to bridge the gap: NAS = beaglebone black + USB HDD

Elecraft released a new small size qrp transceiver about half the size of the KX3 series.

Some technical differences with the KX3 is that the KX2 is 80-10meter where the KX3 has also 160m, 6m and optional a 2m add on.
