You can check the real-time positions of aircraft and ships within the reception area on your PC screen, either at home or outdoors. You can enjoy it personally without an amateur radio license. It seems to have been popular before Windows 10, but there haven't been many reports since Windows 11. This time, I was able to confirm reception on Windows 11, so I will be listing it. The set contents are as follows: ① Software radio device ~ RTL-SDR.COM BLOG V3 * Thermal pads are included because heat dissipation measures were necessary. ② Receiving antenna lead wire RG58 (both ends L-shaped SMA male) approx. 1m ③ Dipole antenna ~ NIPPON ANTENNA NR801 * For AIS signal reception (ship position confirmation). FM radio waves can also be received. The antenna length is about 1/4 wavelength, so it can be adjusted with a telescopic antenna. ④ Feeder line approx. 1.3m ⑤ UHF/VHF/FM MATCHING TRANSFORMER (Matching transformer) ⑥ F-male to SMA-female adapter ⑦ Arrow-line type ground plane antenna construction parts * For ADS-B signal reception (aircraft position confirmation). Commercial products are expensive, but you can easily make one for research purposes by referring to the attached photos. Details: Radiator (vertical element) 1 and radial (ground element) 4, and 4 x 200mm of 1.6mm diameter bond wire (soft copper wire) (one is spare). * The radiator length is about 5/8 wavelength, and the radial length is about 1/4 wavelength. Spread the radials at an angle of about 20 degrees to the radiator in four directions. 4-hole panel mount N-female to SMA-female N-male to F-female adapter Next is a bonus. Photo 6: 1090MHz SAW Filter & LNA. This is an active SAW filter that improves reception performance when receiving aircraft signals. Voltage can be applied in the same way as smartphone charging. Operation has been confirmed. Regarding the construction of the PC reception system, various methods are published on YouTube, etc., so please refer to them. This is for research purposes only, so it is configured to allow reception confirmation on a desk indoors. If you are interested, please consider it.
