Handewitt Perseus site
by DL2LBP
Since I've started putting up a remote reception site for the Perseus receiver, here is some info about it. It is located in
Handewitt (scroll down!), Schleswig-Holstein, in the very north of Germany, only 5 km from
the border to Denmark. The
Perseus is a software defined receiver for 0-40 MHz
with many options that
can be controlled remotely by everyone around the world who has the latest
Perseus 4.0a software installed.
Actually, you can only obtain it (beyond trial mode) if you buy a receiver or at least plug one in once.
But it's a great device, I can only recommend it.
My Perseus server is on
irregularly, biggest chance on the weekends. Usually it is connected to an
ALA1530S
magnetic loop antenna in random directions. It's installed about 7 meters above ground and 10 meters from
the house. Only fields to the west but some electric fences produce sparks, depending on the
humidity. So I suggest you put on the
spark rejection.
The strongest signal on MW is the 702 KHz Flensburg transmitter in 13 km distance
with 7.5/2.5 KW(day/night). The ALA1530S has 10dB pre-amplification. That is why the red "Clip" indicator often shows up.
So it's no loss if you put on the
10dB attenuator, at least for MW.
Below you can see a
5 element FM (88-108 MHz), and a
4 element for OIRT-FM for sporadic E and MS (65-74 MHz, actually a channel E4 antenna).
The computers' power supplies produce some HF noise, it's acceptable though. I get the best results in accu mode with my laptop but
in server mode the PC is usually connected to AC.
If you look at the
port you can distinguish whether it's my PC (8014) or laptop HP Compaq 6715s (8015).
DSL upload bandwidth is 500 kbps.
