AMSAT-DL-Doppelkonverter - fehlende DATV-Spiegelfrequenzunterdrückung und Oberwellenmischung mit 4G-LTE-Sperrfiltern von Goobay ( 5-790Mhz ) mit Gleichstromdurchgang an beiden Konvertereingängen nachrüsten ! Eine ausführliche Begründung habe ich soeben an die AMSAT-DL-geschickt.

DK8KW : UPLINK - PATCH VS HELIX - what's better , beacons should be some 55dBm -ish

Good morning, is anyone here who knows, what EIRP the CW beacon DL50AMSAT currently has? I would like to compare it to my own station. TNX!

OH3WE What do you mean by 70dB ???? How many dB above the beacon?
OH3WE Monday, 8:46 am

F5BUU as a bad example.
OH3WE Monday, 8:45 am

WHY WHY why many SSB signals at 70 dB!!
