Hello Every body.

What type op doppler antenna give best results indoor
on the loft ?

I think the groundplate 4 monopole antenna array because it looks a bit upwards
so not so much near by vincinity groundreflections.

See picture hi..

PA3BNX:
Hello Every Body,

I did fix some issues with the SuperSimpleArduinoDoppler

I use now for the doppler rotation timing timer2

It does run now on 500 700 or 900Hz.

Today 30-may-2015
Today 03-june-2015 Again update
Now with a flutter count.


I updated the arduino doppler software

It now uses the EEPROM.write and read to store
Doppler frequency, CW/CCW and Calibration offset

I also changed the 1k series resistor in the arduino doppler shield after the decoupling C 4u7 into 100R
So my scanner RX doesn't has to be so loud hi..

Work in progress  :-+



Try it

PA3BNX:
Hello Every Body,

I did add a speaker to my arduino SuperSimpleArduinoDoppler

And I fixed again a bug in the Arduino Code.

There also is a new Mymapping  file on our PI4WAG site 1.55

It has fixed averaging in the arduino terminal etc...

Today 01-july 2015 update Arduino3.txt
Some bugs fixed.

PA3BNX:
Hello Every Body,


Nice doppler You Tube
