Waiting for QRPver 1_v.3

In order to have an HF transmitter when I am on the road or when I am climbing a SOTA summit, I have ordered a QRPver 1_v.3. This device works on a single HF band that you choose when ordering. I chose the 20m band version (14,000 to 14,350 MHz) which seems to me to be a good compromise between good propagation and ease of installation of an antenna. Moreover this band is rather well used in digimode.
