Members of The Norfolk Coast Amateur Radio Society are a group of like minded individuals with an interest in radio experimentation and, in particular, antenna design. We also have a small group of members interested in contesting particularly using morse code (CW).

MX0NCA-2 DX Cluster Node

The club operates a DX Cluster node providing both normal and RBN (Reverse Beacon Network) spots. This is a filtered node optimized for UK and Western Europe. Therefore the node only serves spots where the SPOTTER is in CQ Zones 14, 15, 16, 20 or 33 ie Western Europe/North West Africa. In addition, spots for FT4 and FT8 signals are removed from the normal spot stream.

To get FT8 and FT4 spots you MUST turn on the RBN connection (see below). You will then get both “normal” and RBN spots at the same time.

The connection details are:

Node: MX0NCA-2
Port: 7373

To turn on all RBN spots send the telnet command set/skimmer
To turn off all RBN spots send the telnet command unset/skimmer

You can select specific skimmer modes eg use:

set/skimmer CW – will turn on only CW skimmer spots
set/skimmer RTTY – will turn on only RTTY skimmer spots
set/skimmer FT8 – will turn on FT8 and FT4 skimmer spots

Note that RBN skimmer spots are also filtered; you will see RBN spots where the SPOTTER is in CQ Zones 14,15,16,20 or 33

Club SDR Receiver

The club provides an HF SDR receiver (KiwiSDR) which can be operated over the internet using a standard browser . The receiver is located in the town of Cromer on the North Norfolk Coast and covers 0.3-30MHz. The antenna is a loft mounted Wellbrook Loop directed North/South.
