My MW-SW and FM-equipment / antennas |
This photo is taken at my home in Naantali (bigger photo) MW/SW-receiver: - Ciao H101 (SDR-receiver, bought 2007) and Grundig Satellit 600 (bought 1985) Antennas: - 80 meters long "L" (directed to North, only possible direction) - 200 meters long "L" (directed to South, only possible direction) I live in quite urban area with a lot of houses around (luckily also some woods). Very often I have a lot of noises covering all MW/SW-bands and it is impossible to listen. I don't know where these intererencies are coming from. TV-sets? |
This photo is taken at my home in Naantali (bigger photo) FM-receivers: (all with 80 kHz or 110 kHz filters) - Marantz ST-450 (87.5-108; over 20 years old but good with high local signal levels!) - Sony ST-S311 (87.5 - 108.0 MHz; frequency scanning possibility) - Yamaha T-80 - Behringer-mixer and C-casette / minidisc-recorders - FM-phaser (I can phase out some local FM-stations with it and 2 antennas) - Conrad RDS-decorder (connected to PC) FM-antennas: Mast 1: - 8-element horizontal yagi with Voltage Controlled Amplifier ( amplifies 2-3 MHz at a time) - 2 x 8-element vertical yagis stacked together - Skyking rotator to choose direction of these antennas Mast 2: (not visible on the photos) - 8-element horizontal yagi - Dipole for TV-channel E3 (for monitoring Sporadic E's MUF) - all coax wires are about 35 meters long from the roof to receiver My problem is high-power YLE-FM-transmitters 13 km away here (to SE-direction, 6 x 50 kW). This means that my receivers must stand quite high signal-levels. Also wide-band amplifier is not possible to use. Well, this could be worse of course. |
