What is Wsprnet?

The Weak Signal Propagation Reporter Network is a group of amateur radio operators using K1JT’s MEPT_JT digital mode to probe radio frequency propagation conditions using very low power (QRP/QRPp) transmissions. The software is open source, and the data collected are available to the public through this site.

What is a WSPR beacon?

A WSPR (pronounced ‘whisper’) beacon is a low power radio transmitter operating on amateur bands from 2m to 160m or approximately 144MHz to 1.8MHz respectively.

What is the purpose of WSPR?

Introduction. WSPR (pronounced “whisper”) stands for Weak Signal Propagation Reporter. WSPR implements a protocol designed for probing potential propagation paths using low-power transmissions. Normal transmissions carry a station’s callsign, grid locator, and transmitter power in dBm.

What are the ft8 frequencies?

FT8

Can WSPR find MH370?

WSPR technology can be used to detect and track aircraft. This paper underpins the flight path report published 31st December 2021 which provided the findings every two minutes during the entire flight of MH370 from 7th March 2014 16:42 UTC to 8th March 2014 00:20…

What is FT8 mode in ham radio?

Worldwide. Short Description. FT8 is an extremely-weak-signal amateur radio mode that transmits very limited communications. JS8, a variant of FT8, can send full conversations and relay messages. I/Q Raw Recording.

What mode does WSPR use?

WSPR was first released in April 2008. It uses a transmission mode called MEPT-JT. MEPT stands for Manned Experimental Propagation Transmitter and the JT represents the initials of Joe Taylor himself which also appear in his callsign.

What is JT65?

JT65 is a digital protocol intended for Amateur Radio communication with extremely weak signals. It was designed to optimize Earth-Moon-Earth (EME) contacts on the VHF bands, and conforms efficiently to the established standards and procedures for such QSOs.

What can I do with WSPR?

Is FT4 better than FT8?

T/R sequences are 6 seconds long, so FT4 is 2.5 × faster than FT8 and about the same speed as RTTY for radio contesting. FT4 can work with signals 10 dB weaker than needed for RTTY, while using much less bandwidth.

Is FT8 upper or lower sideband?

When we think of “Band,” we’re usually talking about, say, the 40M band, or, at least, the cw, data or voice portions of it. But FT8 is an extremely narrowband mode, around 50 Hz wide. In the case of 40M, you set your radio to upper sideband (yes, upper, even on 40M and 80M) and tune it to 7074 kHz.

Is Ocean Infinity still looking for MH370?

In a dramatic development, Ocean Infinity has committed to finding MH370 with a new search in early 2023 or 2024. Speaking at the 8th anniversary of the disappearance of MH370 Ocean Infinity CEO Oliver Plunkett (below) told the next of kin that the company was committed to finding the missing Boeing 777.

Is the search for MH370 still going on?

The search based on these coordinates was resumed in January 2018 by Ocean Infinity, a private company; it ended in June 2018 without success. In March 2022, Ocean Infinity committed to resuming its search in 2023 or 2024, pending approval by the Malaysian government.

Is FT8 killing ham radio?

So, will FT8 kill ham radio as some have posed? True, it is mostly automated. True, it reduces the skill required to make DX contacts. True, it removes conversation from the QSO the same as is true of most DX chasing contacts on any mode.

What is the most popular ham radio digital mode?

when hams worked out techniques of connecting mechanical Teletype keyboard/printers to amateur gear using FSK and AFSK modulation. There are too many different modes to list individually, but here are some of the major ones: FT8 – In 2018 it is by far the most popular digital mode for award chasing and working DX.

What is FST4 mode?

FST4 is optimized for two-way QSOs, while FST4W is for quasi-beacon transmissions of WSPR-style messages. FST4 and FST4W do not require the strict, independent time synchronization and phase locking of modes like EbNaut. The new modes use 4-GFSK modulation and share common software for encoding and decoding messages.

What are the FT8 frequencies?

What is FT8 mode?

The FT8 digital mode is the latest in a series of weak signal applications for amateur radio. Conceived originally for enhancing esoteric propagaint modes such as high speed meteor scatter and moonbounce, Joe Taylor (K1JT) developed a series of applications including FSK144, JT6M, JT65, and JT9.

What is the point of WSPR?

WSPR (pronounced “whisper”) stands for “Weak Signal Propagation Reporter”. It is a protocol, implemented in a computer program, used for weak-signal radio communication between amateur radio operators. The protocol was designed, and a program written initially, by Joe Taylor, K1JT.

How much power does the FT8 use?

Maybe you should run 5 watts until you get the hang of FT8. After say 1 month up that to 10 watts for 6 months. After that go all the way to 50 watts if your rig is rated at 100 w.

What frequencies are used for FT4?

As initial guidelines we suggest the following default dial frequencies for FT4: 3.595, 7.090, 10.140, 14.140, 18.104, 21.140, 24.919, 28.180, 50.318, 144.170 MHz.

Who is funding Ocean Infinity?

Multimodal transport and logistics group Samskip and marine robotics specialist Ocean Infinity have secured €15 million (US$15.8 million) in funding from Norwegian state enterprise ENOVA for their project to build two hydrogen-powered, remotely controlled and autonomous-ready container ships for delivery by 2025.
