Measuring
SWR at VHF/UHF frequency was never a fun. Most radio amateurs just
assume that their 50 ohms cable is matching a beam or GP.
SWR
Meters of analog variety are flooding market, although, not very
economical. LCD meters are bit expensive, crossing a range of over
$100. Although, even if they include “Antenna analyzer” or
something like that, which few of us, use or understand, but
certainly pay a price for!!
LCD
SWR Meter presented here meet many simple task using a micro
controller, especially, dear to all of us, a PIC!!. This time its
PIC16F88. The very basic
purpose to make this project is to encourage radio amateurs to build
their own High Quality LCD SWR Meter at low price, instead of
buying expensive ready made units.
