My home QTH is Wola Justowska, 30-231 Cracow, Poland.
The home station is located between two hills – Wzgórze Św. Bronisławy and Sowiniec, about 230m above the sea level.
Antennas
My current home qth antenna setup:
- 14/18/21/24/28 MHz redesigned homemade 2-element Qubical Quad antenna (2.5m boom) fed at the one common point with 3:1 hybrid balanced to unbalanced impedance transformer. The boom is about 12m above the ground level, sitting at the top of the telescopic military mast and being rotated by SPID rotor.
- 7MHz telescopic vertical with 8 radials (10.30m vertical; 6,8m each radial)
- 7MHz sloped dipole antenna (sloped towards NW) ~15m -> 6m agl
- 2m/70cm j-pole and 2m dipole antenna for hitting local repeaters
Ham shack
- Yaesu FT-450
- MFJ-949d tuner
- K9AY controller + receiver front-end protector
- 2m/70cm trxs
- SDR receivers – RTLs and RSPDuo
Grounding
The military telescopic mast is bonded to two 6m deep ground strips and all coax shields are bonded to the third 6m ground rod at the ham shack entrance – also the ham shack ground bus is connected to the third ground rod. All ground strips and rods are bonded together with an electricity service point assuring the continuity of the whole grounding system.
Weather station
The amateur weather station EFWS2900 type is mounted on the telescopic mast and is connected to the router. All data is being updated to the website and Wunderground service. Real-time data and charts are stored in the “SP9WOL Weather” bookmark. Please feel free to explore weather data from Krakow!
Updates
- Summer 2020 – FD3 OCFD is taken down, not further in use – it is being used at holiday qth outside of the town at the moment.
- Autumn 2020 – 7MHz full-sized delta loop is taken down due to horrible noise floor on 7MHz band – I guess it comes from nearby elec. cables – the antenna was hung 5m away from the cables. It was not further usable on receiving any stations, but the local one – dipole is fine to do so instead, works on 80m and takes less place.
The loop on the ground and K9AY are put up in place of the delta loop to begin tests on receiving antennas.
Visit: RX Antenna test
- K9AY is a winner. It will have its own place due to awesome RX ability on lower hf bands.
