It is always good to see someone having a go. Especially an electronic parts distribution company, something that can benefit our hobby.

24 December to 31 December: 1st Ever Winter Olivia Digital Mode QSO Party

Special Event Week: Dec 24-Dec 31, 2023

The 1st annual Olivia Digital Mode on HF Winter QSO Party, celebrating 20 years of Olivia.

The Olivia Digital DXers Club (we’re on ClubLog!) is holding the first annual Winter Olivia Digital Mode on HF QSO Party, starting at 00:00 UTC, 24 December 2023, and ending at 23:59 UTC, 31 December, 2023.

Minimum logging requirements:  Callsign worked, Band (or Frequency), Mode (I.e., Olivia 8/250, or other variations), Time QSO Started.  You can log more than that, but for the sake of the certificate, please send at least the minimum information per QSO, to NW7US (email is on QRZ profile).  Logs can be any common method, from an .ADI file, to a screen shot.

Full details are on our website:

Olivia, a Multi-Frequency Shift Keying (MFSK) radioteletype digital mode, is an amateur radioteletype protocol designed to work in difficult (low signal-to-noise ratio plus multipath) propagation conditions on shortwave radio (i.e., high-frequency, or HF) bands. The typical Olivia signal is decoded when the amplitude of the noise is over ten times that of the digital signal!

Here is an introduction to the Olivia digital mode:

Better Than FT8? Olivia Digital Chat Mode – Raleigh Amateur Radio Society Video

Olivia is the digital communications mode on shortwave (high frequency sub band, or, HF) for amateur radio operators who want more than the “Check Propagation” FT8 mode. This video is an introduction that was presented to the Raleigh Amateur Radio Society ( https://www.rars.org/ ) on December 12, 2023, presented by Tomas Hood, NW7US

Olivia information can be found, here:
https://OliviaDigitalMode.org

Olivia, a Multi-Frequency Shift Keying (MFSK) radioteletype digital mode, is an amateur radioteletype protocol designed to work in difficult (low signal-to-noise ratio plus multipath) propagation conditions on shortwave radio (i.e., high-frequency, or HF) bands. The typical Olivia signal is decoded when the amplitude of the noise is over ten times that of the digital signal! It is commonly used by amateur radio operators to reliably transmit ASCII characters over noisy channels (slices of high-frequency spectrum — i.e., frequencies from 3 MHz to 30 MHz; HF) exhibiting significant fading and propagation phasing.

The Olivia digital modes are commonly referred to by the number of tones and the bandwidth used (in Hz). Therefore, it is common to express the Olivia digital mode as Olivia X/Y (or, alternatively, Olivia Y/X ), where X refers to the number of different audio tones transmitted, and Y refers to the bandwidth in Hertz over which these signals are spread. Examples of common Olivia modes are, 8/250 (meaning, 8 tones/250-Hertz bandwidth), 16/500, and, 32/1000.

The protocol was developed at the end of 2003 by Pawel Jalocha. The first on-the-air tests were performed by two radio amateurs, Fred OH/DK4ZC and Les VK2DSG, on the Europe-Australia propagation path in the 20-meter shortwave radio amateur band. The tests proved that the Olivia protocol (or, digital mode) works well and can allow regular intercontinental radio contacts with as little as one-watt RF power (when propagation is highly-favorable). Since 2005, Olivia has become a standard for digital data transfer under white noise, fading and multipath, flutter (polar path) and auroral conditions.

Olivia can perform nearly as good as the very popular WSJT mode, FT8, and better than FT4.

See you on the waterfall!

Some time spent on the radio.

 The weather here for the weekend was not too great so why not spend some time on the radio? I found the Croatian 9A DX contest to take part in. The solar forecast was not promising but I thought why not spend a few hours on the radio on Saturday and see what happens? Turns out the contest was busy and I managed to practice my CW contesting.  

Below are the results:
