This is a WebSDR receiver, located in Berlin Rummelsburg JO62RL.

It is operated by Sven DL7AD, e-mail sven.steudte@gmail.com . If you want to change the frequency of the WebSDR for special purposes, please write me an E-Mail. The WebSDR is located on top of the roof of the Studio Saraceno. Around 20m above ground level.

Find other WebSDR receivers on www.websdr.org.


There is currently one 5/8-lamda car antenna connected to the 2m channel and a Groundplane to the 70cm channel.

Currently there is a roof to the east because the antenna is not elevated. All other directions should work fine. The antenna can see the horizon. The 2m RTL-RTL receiver has a 18dB-preamplifier and a filter which blocks the FM broadcast band at around 60dB. The 70cm receiver has no filter nor preamplifier currently.
