A class-leading lightweight carbon-fibre mast from SOTABEAMS

Portable specialist SOTABEAMS has launched a new carbon-fibre portable telescopic mast. The Carbon-6 has an extended length of 6 metres (19.6 ft) but weights just 300 grams (10.6 ounces).

Its packed length is only 43 cm (17 inches) making it a mast that can be taken pretty much anywhere.

The Carbon-6 has been designed for light-duty operations and is best suited for supporting the centre of end-fed wire antenna in inverted vee fashion.

It is likely that this will be a popular choice for the portable operator who undertakes more “extreme” forms of travel or just wants to travel light!

RSPdx by SDRPlay

SDRplay

We are pleased to announce a new member of the SDRplay family – the RSPdx

The RSPdx is a replacement for the highly successful RSP2 and RSP2pro SDR receivers, which have been extensively redesigned to provide enhanced performance with additional and improved pre-selection filters, improved intermodulation performance, the addition of a user selectable DAB notch filter and more software selectable attenuation steps . The RSPdx , when used in conjunction with SDRplay’s own SDRuno software, introduces a special HDR (High Dynamic Range) mode for reception within selected bands below 2MHz. HDR mode delivers improved intermodulation performance and fewer spurious responses for those challenging bands.

The RSP2 and RSP2pro design is over 3 years old now, and so the RSPdx has taken advantage of a lot of the learning from our work on the newer RSP1A and RSPduo designs as well as ongoing feedback from customers.

The datasheet for the RSPdx can be found here: https://www.sdrplay.com/resources/RSPdxDatasheet.pdf

RSPdx Videos

These three videos give more information as follows:

This introductory Video shows the features and demonstrated the RSPdx in action over a wide range of frequencies:

This unboxing video talks some more about what you can expect to see and some of the key benefits:
Over on the Hamguides YouTube channel, Mike, KD2KOG introduces the RSPdx and looks forward to receiving feedback on ideas on where you’d like more video guides

In the coming weeks, links to more demos and articles relating the RSPdx will be added to our apps and support catalogue: https://www.sdrplay.com/apps-catalogue/

The pricing for the RSPdx will be similar to the RSP2pro (approximately $199 USD or £159 GBP excluding taxes) and the current schedule is for units to be available to buy from around 22nd November – wither direct from this website (click on purchase) or from our authorised channel partners and resellers: https://www.sdrplay.com/distributors/

About SDR Play RSPdx

The SDRplay RSPdx is a complete redesign of the popular RSP2 and RSP2pro multi-antenna receiver. It’s a wideband fullfeatured 14-bit SDR which covers the entire RF spectrum from 1kHz to 2GHz.

Combined with the power of readily available SDR receiver software (including ‘SDRuno’ supplied by SDRplay) you can monitor up to 10MHz spectrum at a time.

The RSPdx provides three software selectable antenna inputs, and an external clock input. All it needs is a computer and an antenna to provide excellent communications receiver functionality. A documented API allows developers to create new demodulators or applications around the platform.

The Adalm Pluto SDR Active Learning Module

The ADALM-PLUTO active learning module (PlutoSDR) is an easy to use tool marketed by Analog Devices Inc. that can be used to approach the Software Defined Radio (SDR) technology or to learn the basic concepts and topics of electronic engineering or again to explore advanced topics in the field of radio frequency communications, both in “instructor” and “self-learning” mode.

sdr pluto

PlutoSDR allows students to better understand the real RF world around them and is applicable to all students, at all levels, in all areas. Learning in a practical way with PlutoSDR will guarantee a solid base particularly suitable for students who follow a scientific, technological or engineering study path.

The PlutoSDR active learning module is a tool that “amplifies” the relationship between theory and practical activity in the field of radiofrequency.

PlutoSDR provides a personal portable laboratory that, when used with a host, can increase classroom learning. A variety of software packages like MATLAB or Simulink provide an innovative graphical user interface (GUI), which allows intuitive use and minimizes the learning curve, allowing students to learn faster, work smarter and explore more!

Robin Getz looks at various RF problems (third harmonics of mixers, RF pollution, required RF filters), and how new innovated tools, and open source software can help measure and mitigate these issues.

The ADALM-PLUTO active learning module is a learning tool for everyone.

Based on the Analog Devices AD9363, it offers a reception channel and a transmission channel that can be managed in full duplex, able to generate or measure analog RF signals from 325 to 3800 MHz, up to 61.44 MSPS, with a width 20 MHz band. PlutoSDR is completely autonomous, truly pocket-sized (it fits perfectly in the shirt pocket) and is entirely powered by USB with the default firmware. With support for OS X ™, Windows ™ and Linux ™, it enables the exploration and understanding of RF systems regardless of where the user is or when.

In practice, adding RX filters, an antenna and a pair of VHF-UHF-microwave amplifiers with PlutoSDR it is possible to build a 144-430-1200-2400 MHz quad-band, both for SSB use and for digital transmissions, using the PC as control console SDR. With the necessary adjustments it also accepts full-duplex for satellite use.

The cost is just over 100 euros, truly within the reach of every experimenter.

JOTA-JOTI Purpose

Jamboree on the Air – Jamboree on the Internet (JOTA-JOTI) is a fun and exciting annual experience for all young people in Scouting using the widest range of technology communication channels to educate, promote cultural awareness, develop tolerance, as well as enhance sharing, collaboration and teamwork, along with building a sense of belonging to the worldwide Scout Movement. It is a “travel-free” Jamboree that takes place wherever you are in the world.

JOTA-JOTI Description

Jamboree on the Air – Jamboree on the Internet promotes a Scout’s sense of belonging to the worldwide Scout Movement and builds cultural awareness, develops tolerance, advocates sharing and collaboration as well as demonstrates teamwork.

It provides exciting opportunities for young people to explore technology and to develop technical skills including fostering innovation and creativity through communicating with other Scouts. A wide range of activities using communication technology are the chief methods of attaining these goals.

JOTA-JOTI strives for a meaningful engagement of as many young people from as many parts of the world as possible annually on the third weekend in October. This weekend is also an occasion to celebrate Scouting and to generate positive energy to support the development of the Scout Movement.

The event seeks to promote quality Scouting in a manner faithful to the purpose, principles and method of Scouting and consistent with the needs and aspirations of young people in today’s world.

The JOTA-JOTI programme shall be a reflection of the Promise, Law, Principles and Method of Scouting, as defined by the WOSM Constitution, and shall also reflect the most up-to-date policies and initiatives of WOSM relating to youth programme for all ages.

JOTA Operating Rules

  • All radio operators must operate their station strictly in accordance with FCC regulations.
  • Stations should try to contact each other by calling “CQ Jamboree” or “CQ JOTA” or by answering other stations sending this call.
  • Any authorized amateur radio frequency may be used. It is suggested that the frequencies listed below be used, at least for a starting point. Once contact is established, you can move to another frequency to leave the calling frequency open for others.
  • Any amateur mode of operation can be used such, as CW, SSB, PSK, SSTV, FM, and satellite. The more modes in operation, the more exciting the event will be for the Scouts.
  • JOTA is not a contest. The idea is to contact other Scout stations and allow as many Scouts as possible to talk to other Scouts and learn about who they are and what they are doing. You might think about counting the Scouts on both sides of the QSO rather than the number of QSOs!

JOTA Suggested Frequencies

  • All frequencies are shown as megahertz.
  • Primary HF recommendations are for General Class licensees. Technicians may take advantage of 10 m and VHF/UHF for voice communications.
  • After contact is made on Calling Channel or frequency, move to another channel or frequency for QSO.
  • Experiment with modes prior to JOTA or Radio Scouting demo. ‘Murphy’s Law’ prevails!
  • Use web search tools to find lots of helpful information about any of the modes commonly used for JOTA and Radio Scouting.
  • WOSM (World Organization of the Scouting Movement) calling frequencies are shown to indicate center of international activity.
