DL9LBG WSPR transmitter
Now receiving on 60 m band (RX only)
This webserver and the WSPR generator/decoder (Weak Signal Propagation Reporter) both work on a Raspberry Pi mini computer located in Lütjenburg/North Germany (Locator JO54hh).
DL9LBG is listening NOW to WSPR sigs on 5.2887 MHz +/- 100 Hz (60 m band) - RX only!
The WSPR software by K1JT is running on a Raspberry Pi which is connected via a cheap USB audio dongle to an FT-857D which produces about 2 watts (33 dBm) hf output. I use a so called Fuchs-antenna that is 20.5 mtrs of wire fed at the end at high impedance (2*λ) with a resonant circuit transformer. The wire is 18 mtr up from the ground.
WSPR transmitter plus webserver on one mini computer and the power input is only 3.5 watts. Good power efficiency, I think. On this old Raspberry Pi 2 additionally an MMDVM-DVMEGA does a good job as a local DMR-/C4FM-YSF-Hotspot on 433.675 MHz (WSPR and webserver take few ressources, there's enough mem and CPU-power left for MMDVMHost).
Pse QSL to michael [ät] dl9lbg.de - tnx!
