Sheet 4 · The written guides

Build it
yourself

What to buy, what to build, and what to do with it if you want a station of your own. Each guide is intended to be a complete walkthrough for each discrete aspect of the station, with a complete station setup guide covering everything I did.

You can print a guide, or give its plain-text file to a coding agent. Every guide ends with a list of what I did not run or could not confirm. Read that list before you trust a step.

One guide for each episode
EpisodeGuideWhat it builds
01ADS-BA step-by-step guide to receive ADS-B aircraft positions on 1090 MHz at home with one antenna, one USB dongle and one small computer, and to see them on your own live map.
02Planefence and Plane-AlertA step-by-step guide to get an alert when an unusual aircraft flies in range of your own ADS-B receiver, with planefence, plane-alert, a community watchlist, Discord and Home Assistant.
03AISHow to receive AIS ship positions at home with a marine-band antenna, a USB radio, one small computer and AIS-catcher, and see the ships on your own map.
04ACARS and VDL2A step-by-step guide to receive the text messages that aircraft send, ACARS and VDL Mode 2, with one antenna, USB radios and free software.
05ShortwaveA build guide for one receiver that hears all of shortwave, 0 to 30 MHz, at the same moment. An RX-888 Mk II, a small active loop and ka9q-radio on an x86 PC serve many channels to many programs.
06HFDLA step-by-step guide to receive HFDL, the shortwave data link of aircraft over the oceans, with dumphfdl. One band with one tuned radio, or every band at once with a wideband receiver and ka9q-radio.
07WSPR and FT8A build guide to receive the slow amateur radio modes WSPR, FT8 and FT4 on shortwave, with one receiver and WSJT-X or with a wideband receiver and ka9q-radio, and to report what you hear.
08Weather FaxReceive marine weather charts (radiofax, or weather fax) and NAVTEX text warnings at home with a shortwave receiver, a wire or loop antenna and the free program fldigi.
09Distress Calls, Beacons, and HFGCSA walkthrough to receive three shortwave signals at home with free public programs. Ship calls (DSC), the 18 beacons of the NCDXF/IARU International Beacon Project, and US Air Force voice broadcasts (HFGCS).
10VLF and Solar FlaresA build guide for a sudden ionospheric disturbance (SID) monitor. A wire loop antenna, a sound card and the free program SuperSID log the strength of very low frequency navy transmitters, to show solar flares.
11Antennas and filtersA build guide for the radio-frequency chain of a receive-only station. It covers antenna, cable, filter, splitter, limiter and amplifier, and a method to measure each change.
12The Station MonitorA guide to put every feed of a home radio listening station on one web page, and to know when a feed has stopped, with free public programs or with a small program of your own.
13Numbers StationsA walkthrough to listen for numbers stations at home and record them on time from Priyom's public schedule, with one SDR radio or a wide shortwave receiver. It also covers the Russian navy's letter beacons and the Buzzer.
14RadiosondesA step-by-step guide to receive the radiosondes that weather balloons carry, 400 to 406 MHz, with one USB radio, a small computer and the free program radiosonde_auto_rx.
