We setup a new 70cm amateurradio repeater in cologne under the callsign DB0CGN (actually in testmode).
QRG 438,7875 MHZ/431.1875 .
CTCSS 74,4 KHZ (send), CTCSS 254.1 khz (receive)
Right now this relais is in a testmode.
The estimated minimum distance is around 39 km, based on a 1,80m Level of a portable station and the Relaisposition which is around 70m above ground.
This is shown in the attached google maps.
The german regulation authority calculated a theoretically distance of 70km with 10W EIRP power.
