PI4WAG - Pseudo Doppler

[M0ATZ]

yes, the ability to upgrade to more antennas is certainly a major benefit over the 4013 / 4001 setup. Nice design. I'll work on the artwork in ms paint and upload once complete over the next couple of days. Should be fun building this variation, thanks again for your hard work.

Hello Every Body,

Here is a nice site from PA8W with Drawings etc
for a Autonome Doppler with or-dinairy c-mos chips

All very cheap and of course the reference output
for my software sounddoppler.exe

It also has 32 leds and softswitching
