Revision: 1.01 – 12/11/2018
Here you find my installations guide how to install dxspider on raspberry Pi. Also you can find more information here wiki.dxcluster.org. If you need help please contact with me.
Furthermore if you don’t want make manual installation you can used my script for the installation and configuration Dxspider.
1. Fisrt change user from pi to root
$ sudo su -l
2. Create user sysop and setup password
# adduser -m sysop # passwd sysop
3. Install perl libraries
# apt-get update # apt-get install libtimedate-perl libnet-telnet-perl libcurses-perl libdigest-sha-perl libdata-dumper-simple-perl
4. Now download and unpack the DX Spider distribution, set symbolic links and group permissions. Copy the tarball to /home/sysop and do the following.
# cd ~sysop # wget http://www.dxcluster.org/download/CVSlatest.tgz # tar xvfz CVSlatest.tgz # ln -s ~sysop/spider /spider # groupadd -g 251 spider
If you do not have the command ‘groupadd’ available to you, simply add a line in /etc/group by hand.
# vi /etc/group
You also need to add some others to the group, including your own callsign (this will be used as an alias) and root. The finished line in /etc/group should look something like this:
My problem was when I worked in 40m ( with power over 40 watt) my the TV (LCD) was started automatically start up and shutdown.
I tried with differend ways to solve this problem but the result it was disappointing. After lot of hours studing I found the solution.
The Combined Braid Breaker and High-Pass Filter.
This device prevents HF signal currents from flowing down the inner or outer of the co-axial cable. L1 has a low reactance to HF or VHF signals, thereby bypassing the interfering current, whereas C1 and C2 have high reactance to HF and VHF, effectively locking signals to the receiver. L2 provides a further short-circuit (to HF and VHF signals) across the connections on the receiver side of the filter. Continue reading…
