Antenna: 2 wires 150 meter uphill. 2 wires 150 meter downhill.

Transmitter: 100 W output.

Receiver: TS120 V plus transverter , RF and AF filtering.


We had lots of problems with the ground system. When the LF-Station was connected to mains ground there was noise with s9. After disconnecting from ground the receiver was calm but when transmitting the equipment was hign voltaged. May be a few earthstakes would be the solution. We could not run more than 100 W because of flashovers at the downhill wires interfered the RF-Station which worked simultaneously.

The antenna current was about 2.5 A eff.

Orineted at the signal reports we received from DJ2LF, DK6NI and DJ7RD the efficiency factor was in an acceptable range. So I don`t understand the poor response.

The RX situation after 11:00 utc was very difficult because of strong thunderstorms in south germany area. We heared pa0bwl and ok1fig for a short time but no qso occured. We also heared and called dj9ie (many times) and dj5bv but got no answer. dk8kw answered a cq-call with a goor readable signal but suddenly disappeared. No G-station was heared during the weekend.


It was a nice weekend in HB0. The weather was fine and we had no rain. We managed over 4000 qso`s on the rf bands. We`ll surely vist hb0 again. May be 136 kHz will be activated again.
