DH2VA Friday, 3:53 pm

Guten Morgen was ist das Limit ? Exact Stärke der Bake ? Ich höre die Bake mit 70,2 db mein Signal ist in dne Spitzen 1,4-1,7 db lauter ist das schon zuviel oder gibt es einen Grenzbereich?

DK8KW : UPLINK - PATCH VS HELIX - what's better , beacons should be some 55dBm -ish
DK8KW Monday, 9:56 am

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!
DB2OS Monday, 9:33 am

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!!
