DCF 37 as reference is more than strong enough. WRW (NDB Wrozlaw) was hear= d on 525 kHz, some other NDB too. But usually the weak HAM signals in this= bands can not be heard/seen because of too much QRM. One of the ugliest QRM sources is the waterfall display of ARGO which can= be heard much to loud. The QRM is really HF, not a problem of the soundcard. I have Siemens Thinkpad Laptop. Does anyone know this effect??
