  • 0530-0830 UTC (3-6pm ACST) will see 40m targeting VK/ZL again
  • During the middle of the day on Sunday we may activate on 15m as well targeting Asia/Japan/Northern VK. Keep watching the AREG blog for details.

Many stations are already gearing up to take part and the operator team is getting ready to head to the station of Chris VK5CP for the weekend where the activity will originate from.

I’m a Foundation License holder – how can I get involved?

One of the very recent questions however was “How can Foundation Licensees take part in this event? While it is true Australian Foundation License holders can’t transmit FreeDV, they can still receive it. So why not have a go at installing the software on your PC, connect your radio’s audio output to your PC soundcard and have a listen around the bands for FreeDV signals!

You can provide feedback to the FreeDV operators during this weekend via Internet Relay Chat (IRC) on irc.freenode.net. (http://webchat.freenode.net/?channels=freedv) via the #freedv channel.

The FreeDV QSO Finder will also be used during the weekend. You can take a look and monitor the action here: http://qso.k7ve.org/  Note that the login system for this page uses the HamQTH Callsign Database, which doesn’t have many newer Australian Callsigns. If you get a “Callsign not found” error, you will need to register at: http://www.hamqth.com/register.php If you are listening only, you can log in as “SWL”.

You can also send us an SWL QSL Card via www.eQSL.cc! When a user sets the SWL/HAM checkbox in his Profile to SWL, it automatically forces all incoming and outgoing cards to say ‘Confirming SWL Reception’ instead of the usual ‘This Confirms Our 2-Way QSO’. If you are an SWL, just make sure to go to My Profile and set yourself up as an SWL. If you are a ham, when you send an eQSL to an SWL, it will automatically put the correct wording into the card.eqsl-header

VK100ANZAC QSL Cards for this event

All amateurs can also receive a QSL card for working the VK100ANZAC freeDV station. The WIA VK100ANZAC QSL card policy is as follows:

QSL cards are softcopy only via:

vk100anzacLooking forward to working you all during the FreeDV QSO Party this weekend!

 

Hints & Tips for getting started on FreeDV

Posted on by

The AREG FreeDV QSO Party is getting closer and now would be a great time for you to start setting up their radios so that you can join in on the weekend of September 12th and 13th! More information about the QSO party is available here (click).

The following are some resources you may be interested in to help get your FreeDV station up and running on the air.

What does FreeDV Sound Like?

Firstly, what does a FreeDV Contact sound like in comparison to SSB? Here is an excellent demonstration of this by N4DVR.

How to setup a FreeDV Station?

You can start operating on FreeDV by downloading a program for your computer, and then connecting it to your HF radio via your sound card. The software is an open source program available from the following links:

Next, you need to get your FreeDV software installed on your PC and configured. The following video tutorial is great for explaining how to set up the software.

Once you have the software configured it is time to connect it to a transmitter! The next video is from a presentation made by David VK5DGR at the AREG club meeting where some of the factors to consider when driving a HF radio with FreeDV were discussed.

In summary:

  • Less Power is usually better
  • Do not run any compression on transmit
  • Back the transmitter power off such that the ALC function is barely being activated
  • Do not run any receive filtering

The main reason for these tips is that distortion of the signal leads to bit errors. While you may get more transmit power, the signal quality being transmitted will be degraded to the point where even under very good HF path conditions decoding the signal will be very difficult indeed.

Where to go for more support?

If you want more information about FreeDV please visit the www.freedv.org website or log onto Internet Relay Chat (IRC) on irc.freenode.net. (http://webchat.freenode.net/?channels=freedv) and connect to the #freedv channel.

 

International Lighthouse & Lightship Weekend 15/16th August

Posted on by

illw-net

This annual amateur radio event was started in Scotland by John Forsyth, GM4OOU, and the late Mike Dalrymple (GM4SUC), both members of Ayr Amateur Radio Group (AARG). Through the years the event has grown probably far beyond what John and Mike envisaged for it all those years ago. The fact that some 85 countries have been represented in this event since inception clearly shows that it is well on its way to becoming a premier event on the ham radio calendar.

The basic objective of the event is to promote public awareness of lighthouses and lightships and their need for preservation and restoration, and at the same time to promote amateur radio  and to foster International goodwill.The Lighthouse weekend is fairly relaxed and usually has a decent turn-out of chasers and participants. It is genuinely a good fun day out!

Bob VK5FO is organising a station to activate VK5ARG from Marino Rocks Lighthouse. The plan is to meet at the Carpark at the end of Nimboya Rd, Marino, at around Midday on Saturday 15th. From there, we will set up in the park up towards the lighthouse, in the Marino Rocks Conservation Park – which also qualifies for the SANPCPA.

The station will consist of a 40M inverted V and a FX-4A QRP tranceiver for the VK contacts and a pair of phased Verticals on 20M beaming long path Europe using an Elecraft KX3.

The plan is to operate the station until dark on the Saturday before finding somewhere local to eat before driving home. Please let Bob VK5FO know if you are planning on coming out to operate the AREG station. Note if you do want to come, you dont need to bring anything except a chair.

Note: The ILLW event does does co-incide with the RD Contest.  While VK5ARG will not be participating in the RD contest, we will give out numbers to those who are :).

 

FreeDV QSO Party Weekend – September 12/13th

Posted on by

f-layer2The Amateur Radio Experimenters Group would like to invite all amateurs interested in HF digital voice communications to join us on the weekend of September 12th and 13th in a FreeDV Codec2 digital HF voice QSO Party! AREG in conjunction with David VK5DGR, one of the co-creators of FreeDV, will be activating a FreeDV HF station across the weekend under the Wireless Institute of Australia (WIA) special event call-sign VK100ANZAC. The aim is to encourage as many amateurs as possible to “come and try” this new digital HF mode, joining us and as many other FreeDV operators as possible in making contacts via digital HF voice around Australia and across the world.

Bands and Times?

Various bands will be used, with the primary call channels being 14236kHz +/-QRM and 7175kHz. The VK100ANZAC net control station will be listening and intermittently calling on FreeDV on the following bands:

  • Saturday evening September 12th from 1130UTC (9pm Australian Central Standard Time (ACST)) beaming short path North America on 20m (west coast).
  • Sunday morning September 13th from 2130-2330UTC (7am-9am ACST) on 20m beaming long path North America (east coast)
  • Sunday morning from 2230-0130UTC (8-11am ACST) will see local VK contacts targeted on 40m
  • 0430-0730 UTC (2-5pm ACST) will focus signals towards Europe Long Path as well as VK on 20m.
  • 0530-0830 UTC (3-6pm ACST) will see 40m targeting VK/ZL again
  • During the middle of the day on Sunday we may activate on 15m as well targeting Asia/Japan/Northern VK. Keep watching the AREG blog for details.

What is FreeDV?tiki-download_file

So, what is FreeDV you might ask? It is a new digital voice mode developed by an international group of amateurs, led by David Rowe VK5DGR. David was recently awarded the Ron Wilkinson Achievement Award for his work on Codec2 and FreeDV by the WIA. FreeDV operates at very low bitrates and narrow bandwidths using an open source digital voice compression algorithm (Codec2) developed by David. As such, it is ideal for use on HF. What’s more, being completely open source, it can be reproduced and adapted/extended by anyone who is prepared to follow the open source philosophy, unlike some other systems which have proprietary elements that limit experimentation.

Why is AREG Sponsoring this?

Why may you ask are we doing this? Like all new modes in their early days, like the early SSB developments in the 1960’s, finding like minded stations to make contact with can prove a little difficult. The aim behind this global event is to gather multiple FreeDV stations on air so that beginners in the mode can find others to make contact with, as well as providing support and help via SSB for those struggling to get the new technology to work. It is the perfect opportunity for you to dust off your radio-PC interfaces or finally wire-up your SM1000 digital voice adaptor and give this unique mode a try!

How do you get involved?

sm1000_enc_smHow do you get involved? There are several ways to get on the air with FreeDV. The most common is to download and install the FreeDV GUI application on your PC, and use a PC to HF radio interface, and a USB headset. More recently the stand alone SM1000 digital voice adaptor has become available which eliminates the need for a PC. Details of how to set up your station to run FreeDV can be found from the FreeDV project’s website http://freedv.org/ .

Technical support during the event will be available via Internet Relay Chat (IRC) via the #freedv channel on irc.freenode.net. (http://webchat.freenode.net/?channels=freedv )

The VK100ANZAC Link

The idea behind operating the FreeDV QSO party net vk100anzaccontrol station using the special event callsign VK100ANZAC was to provide a little extra incentive for amateurs to come and try this new HF digital mode. It will certainly provide a unique QSO opportunity! The weekend in question is also one of significance for the ANZAC story as it commemorates the 26th Infantry Battalion’s arrival at Gallipoli and their subsequent deployment to Taylor’s Hollow on September 12, 1915. Part of the event will commemorate those who served and the sacrifice they made.

Conclusion

We look forward to making contact with you over the weekend! If you want more information, keep watching the AREG website for regular updates and blogs of the weekend’s events as well as for information on operating FreeDV at www.areg.org.au.

All contacts made will be recorded in ClubLog. Qrz.com will also be updated with the latest QSO information. We will also QSL any cards received either via the Bureau or via EQSL. SWLs will be eligible for a special card if they can confirm a full two way QSO.

Plans are also being worked on for a test and tune event the weekend beforehand. Keep watching the AREG website for details. See you on the air!
