WSPR-homebrew

WSPR standalone transmitter.

Power in this moment 2 milliwatts. (I transmit the code 10 Milliwatts)

Logged by several hamradio amateurs.

The transmitter consists of an Arduino Uno,

an AD9850 a DDSbuffer and pifilter.

I got the code for the arduino of PA1LD .

The emitter of the 2N2222 provides the power.

Antenna is a vertical, also homebrew. I can use this antenna including the

adjustment in a mobile position. The powersupply is also homebrew.

The length of the antenna is 4.5m, including the center coil about 7.5 meters
