So neighbours are bad for DCF77!? ;-) Maybe move your antenna closer to your neighbour, then further away, and compare the results: Most interferences are short range, unless he has a high-power device. If you can build a 77kHz receiver and make the signal audible (it's AM with FM also), you'd clearly hear interferences (Normally you should hear a clear tone with amplitude varying once per second (AM) with a little "scratchy" noise (FM). If the sound is more like frying a steak in a pan, you have interferences ;-) (I'd wish commercial receivers had an audio output for positioning the antenna perfectly) Regards, Ulrich _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
