In AR7030Plus signals come from "empty space" with practically no background noise.. R&S ESH2 being a Measuring receiver with no AGC etc sounds as if waterdrops were falling on ice... (Most of you no doubt understand this difference). I must be lucky to have only slight amount of QRM w ICM (fm 138.83) and Russian Chayka on background. Note: This is after de-activating ISDN installation. --------------------------------------------------- ICM (Ionospheric Cross-Modulation)-Could you please check which stations you possibly can identify on DCF39 138.83 carrier, especially on Lower SideBand. After aurally monitoring ICM for decades I only now have noticed some funny effects with some ICM audio bursts "leaking" down to at least 136.0 kHz (that is 3 kHz down from carrier), this with 500 Hz cw filter while sometimes listening and standing by for hours. As you know ICM effectively filters higher audios. ---------------------------------------------------- 73 and Happy 2000 to all de Vaino, OH2LX ---------------------------------------------------------- V.K.Lehtoranta, OH2LX, POBox 50, FIN-05401 Jokela, Finland ------ Tel: +358-9-4173965 ---- Fax: +358-9-4173961 ------ E-mail: vaiski@dlc.fi - alias: oh2lx@dlc.fi & oh2lx@sral.fi
