HF Antenna Analyser

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.

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

Bitx40 Enclosure - measurement and more details

Here is the Bitx40 enclosure measurements and construction tips.

Now have some inside views.  Note that the speaker is mounted with Plexiglas - didn't occur any better idea to me.

 

 

The front plate is again a piece of Plexiglas,  etched with black paint.
