Remote QTH


My WAN-operable remote listening post located 100 kilometers to the north of Helsinki, Finland.

- there are pictures after the text > click on the pictures to enlarge

I do all my dxing from or at my Remote QTH, which is presented in this page:

- Radios in remote use: Elad FDM-S2, SDRPlay RSP2Pro

- Remotely WAN-operable antenna switching unit Anteni.net MS-S7, inside unit via WLAN to router

- Laptop with SDR-Radio.com Console and Server version 2, SDRPlay Connect, via virtual USB- ports Ergo4 + ILG-database    and Rx_log_Tuner, laptop via WLAN to router

- Router, WAN 4G + Dynamic DNS for managing the changing WAN ip-addresses

- Several clamp on cores everywhere, between antennas and radios an NTi CCMC30 common mode current filter

- all inside equipment grounded to one point before out take to the outside grounding points

- The antennas at the remote QTH:

        - test antennas 2024: 220 meter long horizontal loop and 70 meter short Beverage, see drawing below for more                    details 

- (Multi-end-Beverage, 630 m,  single Beverage, 70 m, both are  3 meters above ground level

          and have far end groundings with 800-1000 ohm metal foil resistors, lightning arresters before

          impedance matching,  Ham Goodies longwire multi UnUn's to RG-58, these Beverages were disassembled in June                2024 due to cutting of the forest trees)

- 40 meters long T2FD-antenna, center 8 meters high, 20 meter long sloping legs, omnidirectional

- 40 meters long modified doubled Double Kaz-antenna

- Everything grounded outside the house to 60 meters of 16 mm2 copper wire in and on the ground + five grounding rods      to a level under  ground frost, antenna wires underground to the outside antenna switch
