SO5CW - DJ5CW's station in Poland

OP Fabian, homecall DJ5CW (QRZ.com / HamQTH) - Visit the SO5CW website with more information!

I am using the callsign SO5CW during my holiday operations from Poland since December 2018 (formerly SP/DJ1YFK). Since September 2024, I am also operating my station remotely.

QTH:	near Chynów, 35km south of Warsaw
Grid:	KO01MW
PGA:	GJ03
RIG:	IC-746PRO (local) / IC7100 (remote), TS-440S (backup)
Ant:	2el/2el/3el (20m/15m/10m) Yagi @ 12m, 40m/80m Inv-V Dipoles @ 8m, 160m Vertical with top load wires (16m + 3*10m), 2m 17el F9FT Yagi

The SO5CW QRSS grabber and WSPR receiver is running at this location on 30m.

In 2008 and 2010 I was also QRV from Poland as SP/DJ1YFK from SP5ZCC / SN5Z (KO02PF). Between 2012 and 2024 I occasionally operated from near Warka, KO01NU.

QSL: I don't collect paper cards any more. If you need a card, please request it by email (fabian@fkurz.net).
I am a member of PZK and DARC, so you can send QSLs to SO5CW via DJ5CW to DARC bureau, or via the PZK bureau (OT-31). All contacts are uploaded to LoTW within a few days of the QSO.

SO5CW Remote Setup

Since September 2024, the station can be remote controlled. Below you'll find a block diagram of the setup.

Internet connectivity is be realized via 4G with a Teltonika RUT240 and a VPN connection to my own OpenVPN server (hosted at a German provider for virtual private servers). Operating the IC-7100 with RemoteRig RR-1258MkII boxes shows a delay of less than 100 ms.

The mast is cranked down to 8m while I am away.
