How to use the WEB SDR in Twente Netherlands to listen 100 kHz to 29 MHz AM FM SSB

http://websdr.ewi.utwente.nl:8901/

The system is currently composed of a "Mini-Whip" antenna, a homebuilt SDR board (as pictured; see here for background) which samples the entire shortwave spectrum and sends all of this via a gigabit ethernet link to a PC, where a special version of the WebSDR server software processes it. The Mini-Whip is based on a design from PA0RDT (google finds it); see here and some older pictures here. The active receiving element is about 5 by 10 cm large. Such an antenna only works well with a good grounding; ours is on top of a 20m high building, the upper part of which is all metal.

When you zoom the waterfall

Example: China Business Radio 2 on 11740 KHz AM mode

In red color are the AM broadcasting bands

In green color the amateur radio bands

This is the waterfall from 100 kHz to 29 MHz

To identify a radio station on shortwave, click on STATION INFO

You have information about the radio station on 6085 kHz

You can see it's not difficult to use this WEB SDR

It's FREE

You can also listen to amateur radio operators

I have listened to 240 DXCC entities on amateur radio bands in only 2 years

Utility stations, etc

Amateur radio on 11 meter band in USB mode (28 MHz)

Utility station in RTTY

Marine weather data sent from Pinneberg, Germany. The data is transmitted via Radioteletype, more commonly known by its abbreviation RTTY. For more details on how this transmission method works, please consult the Wikipedia page on this subject.

Have fun with this WEB SDR or KIWI SDR

Predictions of propagation for shortwave but the best was in 2024

https://www.swpc.noaa.gov/products/solar-cycle-progression

Solar cycle 25 is the current solar cycle, the 25th since 1755, when extensive recording of solar sunspot activity began. It began in December 2019 with a minimum smoothed sunspot number of 1.8.^[3] It is expected to continue until about 2030.^[4]^[5] While it was initially predicted by most scientists that cycle 25 would be relatively weak, solar activity has been much stronger than the predictions.

The best propagation for HAM radio was in 1957

Nice SWL antenna for a cheap price, 3 to 30 MHz

Hari SWL Dipole 3-30 MHz

69,00 €

Hari SWL-Dipole 3-30 MHz - 10m,12m,15m,160m,17m,20m,30m,40m,60m,80m

length 14 meters

UNI-BC Wideband Listening Antenna

The UNI-BC antenna has a constant impedance match of approximately 50 ohms across the entire shortwave range from 3 to 30 MHz. This aperiodic dipole therefore operates with the same impedance on all amateur radio and AM broadcast bands without the need for a matching network when changing bands. It features an integrated balun with a 50-ohm matching element and a dipole length of 14 m. The antenna comes fully assembled with an SO239 connector for 50-ohm coaxial cable, such as RG58 or RG213. It is constructed of high-tensile steel wire with a plastic sheath and is weather-resistant.

With 58 years of experience in the field of worldwide radiocommunication via HF, we predicted already in 2000 that HF e-mail will continue to spread rapidly and will soon develop into the major application of modern digital HF techniques that we have marketed - and used! - for years. Interestingly enough, the immense potential of HF e-mail has not been monitored - let alone realized! - by any other author and publisher so far. Only the new Klingenfuss products for 2025 take this fascinating new trend into full consideration - now! We - who else? - provide hundreds of brandnew HF e-mail frequencies and screenshots. Among our customers are dozens of intelligence, radio monitoring and secret services worldwide: see our never-ending list of references and professional customers!
