Have a look at my new Arduino Nano! I have been hearing about it for the past 2 years as the microcontroller in uBITX radio. This closeup picture

You need a MicroSD Card in NanoVNA to store and recall information. Without the card saving information is not possible.

There are a couple of LEDs, a USB port, on/off switch and multifunction switch on the top panel of NanoVNA. Let us familiarize ourselves with the function of

There are several traces on the NanoVNA, cluttering the screen. Let us see how we can activate each one and also how to make each one disappear.

Setting frequency range and calibration of NanoVNA has to be done each time you change the frequency range. If you have inserted an SD card in the device,

I need an SMA male to SO239 patch cable for using NanoVNA as my antennas terminate in PL259 connectors. Calibration is done using a PL259 Calibration Kit for

I received my new NanoVNA by courier today afternoon. I have been waiting for this after purchase for one week. All my antenna projects need this device to

I found this LED running lights circuit diagram from elonics.org. It is a well explained and simple project to make and the author has provided detailed step by

An illustration of the disparity of SWR in external SWR meter and internal SWR meter of the radio follows. The two show different readings after tuning with the

Simple Infrared Receiver Test Circuit. Works with any remote at home like TV remote or remote for air conditioner.
