Dead Link: Lufthansa Amateur Radio Club Frankfurt

Dead Link: Lufthansa Amateur Radio Club Frankfurt
im Lufthansa Sportverein Frankfurt e.V. (LSV) Sparte Amateurfunk.

Die Mitglieder der Sparte sind Funkamateuren aus verschiedenen Bereichen des Lufthansa Konzerns und OM des DARC OV F44 Rhein-Main.


ist unsere Clubstation in der Nähe des Flughafens Frankfurt Rhein-Main. Die Ausrüstung erlaubt Funkbetrieb auf Kurzwelle sowie auf VHF/UHF in SSB, CW und digitalen Modes.


In practice, the majority of university satellites are in Low Earth Orbit and use those sections of the VHF, UHF and S bands which are allocated to the amateur satellite service. GENSO is intended to serve the requirements of such satellites, although the network actually operates irrespective of frequencies and modulation schemes. It is the capabilities of the ground stations that join GENSO, which defines the capabilities of the network.

The most common frequencies are:

144 – 146 MHz VHF band up- and downlink (i.e. 2 m)

435 – 438MHz UHF band up- and downlink (i.e. 70 cm)

2.4 GHz S-band downlink

1.2 MHz L-band uplink

Typically, university satellites might use baseband AX.25 protocol on 1200 AFSK with FM or SSB modulation or 9600 FSK.

Note: the doppler shift calculations in the software (required for tracking) do take into account the presence of up- and down-converters, which may be used to change the nominal frequency range of the transceiver.

Weak Signal Propagation Reporter Network

The Weak Signal Propagation Reporter Network is a group of amateur radio operators using K1JT’s MEPT_JT digital mode to probe radio frequency propagation conditions using very low power (QRP/QRPp) transmissions. The software is open source, and the data collected are available to the public through this site.
