This presentation aims to showcase the hobby and how to get started. All radio amateurs, SWLs, and hobbyists are welcome to attend. This webinar will be an ideal way to introduce someone new to our great hobby and will give good information on how to get started - so spread the word.

The 2022 Annual General Meeting of the South Eastern Amateur Radio Group will take place at 8.00 p.m. sharp on Monday the 28th of February 2022 via the Zoom platform. The committee feels that because it’s a very important meeting and some people might not yet feel comfortable attending public gatherings, that Zoom would be a better option than a physical meeting. It would also allow members and those interested in joining who live a distance away to attend. There will be a limited number of places available for non-members of the club to attend this meeting. Anyone interested in attending is asked to send an email requesting details of how you can access the meeting to southeasternarg /at/ before 6 p.m. Monday the 21st of February.

The next opportunity to listen in on an ARISS event comes up on Monday 14th, when students at the Univeristy of Aachen, in southwestern Germany are scheduled to make contact with astronaut Mathias Maurer, KI5KF aboard the International Space Station. The downlink frequency is 145.800 MHz FM. The ISS rises due west at 11:38 UTC, climbs to an elevation of 70 degrees over Ireland, then sets due east at 11:48. The contact with the students starts at 11:40 UTC, but one can expect to hear traffic between DLØFHA and KI5KF the moment the station comes into view during this long pass.

Digital Voice Mode on HF

FreeDV is a Digital Voice mode for HF radio. You can run FreeDV using freely available Open-Source software, available for Linux, OSX and Windows, allowing any SSB radio to be used for low bit rate digital voice. Alternatively, a commercially available FreeDV adaptor allows the use of this efficient mode without a PC or sound card. FreeDV is being developed by an international team of radio amateurs working together on coding, design, user interface and testing. Aiming to popularize this new mode, its software developer Mooneer Salem, K6AQ announces the Second FreeDV Activity Day on Saturday, February 19th, 2022. He writes: "This event will bring together people interested in HF digital voice on the air for conversation and fun. Contacts using the official application as well as the SM1000 handheld microphone are welcome. As this isn't a contest, there's no pressure to make contacts or send logs, but you can always confirm QSOs via the usual means if you'd like." The FreeDV Activity day is a 24 hour event, starting on Saturday, the 19th of February, at 16:00 Zulu, and ending on Sunday, the 20th of February at 15:59 Zulu. Enabling PSK Reporter in the FreeDV application and joining the QSO Finder are recommended so others can see that you're on the air. A list of the suggested frequencies for the hf bands are

80m: 3.625, 3.643 or 3.693 MHz; 40m: 7.177 MHz; 20m: 14.236 MHz; 17m: 18.118 MHz; 15m: 21.313 MHz; 12m: 24.933 MHz; and 10m: 28.330 or 28.720 MHz.

Note that LSB/DIGL is used below 10MHz as per current convention for voice modes, USB/DIGU otherwise.

On The Air

The GB2RS News Team reports that on the 14th of February 1922, a small group of Marconi employees began a series of experimental entertainment broadcasts on Medium Wave from a wooden hut near Writtle. The callsign of the original station was 2MT. These experiments are now regarded as the Birth of British Broadcasting and the origins of the BBC. On Monday the 14th of February 2022, to commemorate the centenary, Chelmsford ARS will be running GB1002MT. They plan to have HF, VHF and UHF stations on the air from 2pm to 9pm using CW and SSB.

On Thursday the 70MHz UK Activity Contest runs from 2000 to 2230 UTC. Using all modes, the exchange is signal report, serial number and locator.

The ARRL International DX contest is due next weekend, running for 48 hours from Saturday 00:00 UTC, to Sunday 23:59 UTC, The ARRL website has the details in their contest section.

The Propagation Horoscope

A full halo filament eruption last week resulted not only in a disturbed geomagnetic field, but also produced around fourty expensive ionisation trails, thanks to Space-X ignoring space weather warnings, and launching anyway. Two large sunspot regions in the northern hemisphere, joined by two more large regions returning on the eastern limb will deliver more C-flares, some M-flares are likely. The MUF2 reached above 25 Mhz most days, with a critical frequency well above 6 MHz. Another large plume was ejected early Friday morning, the arc of the plasma reached us late on Saturday. In its wake the Solar wind speed will ramp up to above 450 km per second, after the proton count peaked at 15 particles per cubic centimeter late on Friday. NOAA predicts a Kp index of at least three for the coming week. This translates into excellent DX on all Hf bands. Daily opening into the Carribean on 10 and 12 meters should widen further south.

That is the news for this week. Items for inclusion in next week’s radio news

can be submitted by email to newsteam /at/ for automatic forwarding to both the radio and printed news services. The deadline is midnight on Friday.
