YADL, a dummy load for VHF/HF

I recently change my antenna cable and noticed I didn’t have a dummy load (“carico fittizio”) rated for VHF/UHF, so instead of buying or borrowing I decided to make one. I mostly do QRP: power rating isn’t really an issue, but I didn’t want to risk the RFP. I just bought a 50 ohm RFP … Leggi tutto

This Asus laptop had a really convoluted installation history, as even specifying the precise model it is not very easy to uniquely determine the specific driver to install for a given device. It turns out that every re-installation is made is a sort of trial-and-error procedure and the final outcome is, as one can see, not very nice.
