HF Antenna Analyser
Getting the antenna well tuned was a tedious task so far.
Just made a low cost, but much useful HF antenna analyser from the design by K6BEZ.
Many thanks to Beric Dunn for providing this design.
This is now one of the most useful tool in my shack.
Details can be found from

I choose AD9850 DDS module with Arduino Nano. I used 1N34 instead of AA143 - unable to source it yet. Even then it works well for HF range.
Below is the readings of 20m meter range ( of my multi band fan dipole )
And the home brewed 50 Ohms Dummy load
