Accurately measuring cable length with NanoVNA
Update: Now you can plot the impedance vs. distance/time plot. Click here to learn the concept. Original Post: Having a VNA opens up so many possibilities. Just last week, I reviewed the nanoVNA and...

Vector network analysers (VNA) come in all sort of price ranges. Most of them are out of reach for a typical hobbyist. Very few VNAs are available to be bought by someone like you...
Do you build RF circuits? Have you built any antennas? If the answer to any of the two questions is YES, then you know how valuable having a VNA (Vector Network Analyzer) is. Just...
In one of the previous posts we saw how we could transmit DATV using LimeSDR mini. This time we are going to use our LimeSDR mini as a RF source in our home lab....
PLL chips such as the ADF43xx, MAX287x and so on come with an integrated VCO. The frequency range on these PLL chips can extend all the way from few tens of MegaHertz to several...
Transmitting voice is something every ham operator must be doing regularly. There is a breed of hams which only stick to digital modes, while some prefer morse. Some ham operators go above and beyond...
