DL9LBG WSPR transmitter

July 23rd: DL9LBG is not whispering today - sometimes I prefer man made cw operation.

This webserver and the WSPR transmitter (weak signals propagation reporter) both work on a Raspberry Pi mini computer located in Lütjenburg/North Germany (Locator JO54hh).

Currently DL9LBG whispers on 28.126178 MHz (10 m band) with a tx fraction of 20 % (transmitting approx. every 12 minutes).

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. The antenna is a simple dual band ground plane (10 and 15 m) made of some wire and a trap on a fishing rod mounted on the balcony.

WSPR transmitter plus webserver on one mini computer and the power input is only 3.5 watts. Good power efficiency, I think.
