Time to build another tuner (transformer) for my EFHW Wires. This transformer is based on a desing from PA0EJH. For now I don't use a capacitor. I have a 1.5 SWR on 10m which is ok for me. As toroid I use a FT140-43 with 0.70mm enamelled copper wire. The red plug is for a counterpoise (Not tested yet with this transformer) The only thing what I observed is that you get a better performance with a choke balun. For now I can't say more - i have to make more tests

Für alle die Probleme mit dem Zabbix-Agent unter CentOS 7 haben (if) können folgende Schritte durchführen :

grep zabbix_agentd /var/log/audit/audit.log | audit2allow -m zabbixlocal > zabbixlocal.te

Ausgabe sollte in etwa so aussehen :

module zabbixlocal 1.0;

require {
        type proc_net_t;
        type zabbix_agent_t;
        class file { read getattr open };
}

#============= zabbix_agent_t ==============
allow zabbix_agent_t proc_net_t:file { read getattr open };

Wenn alles ok wird das Modul generiert und installiert :

grep zabbix_agentd /var/log/audit/audit.log | audit2allow -M zabbixlocal

semodule -i zabbixlocal.pp

audit2allow befindet sich in folgendem Paket : policycoreutils-python

That is my new 'vintage' RX friend in the shack. It is the JRC NRD-525 (incl. a 240Hz filter). I'm really happy with the performance (so far just tested with USB/CW).

JRC were always at the high end of rx eqpt.
I had a DRAKE R4C and that was an excellent piece of kit for my early SWL days before I sat the RAE😀...73 de GM0PHG

Anyone use successfully Arduino Micro to program a ATTINY84V-10PU? Got always avrdude: stk500_getsync(): not in sync: resp=0x00
No problem when I use a Arduino UNO.

+Adrian Jost I had similar problem with my Pro.mini, and it turned out I had to switch the Tx and Rx wires. Also, make sure you press the reset button right after you click "flash" in the IDE or run avrdude - that is, if your programmer doesn't do this for you - mine doesn't.

At the moment I don't have any Rig :-( But I still practice my CW skills.
Almost daily I spend ten to twenty minutes on http://lcwo.net/ It's really great when you see your up and downs. On the road I use KMT Pro (Android App). I also listen often to http://websdr.ewi.utwente.nl:8901 to copy some QSO.
