Hi Wolf,

If they need some help, i would answer some of their questions, if they=20
have some. So if you and they like, give them my adress.

It will be not so easy to get far enough away from the influence of that=20
transmit antenna. Maybe they need to detune it to make the influence of=20
QRM lower. And they should use a band pass filter combined with an=20
attenuator in the RX line. For us, that's all old stuff and well known=20
of course. I remember similar problems from the kite antenna=20
experiments, even in a quiet location, it was difficult to copy HE3OM on=20
LF although they were copied at JA7NI :-)
