Unlocking Amateur Radio Technology Symposium

Friday 12 April 2019 13:00 – 19:30 followed by cocktails

A workshop presented by the South African Radio League to showcase the exiting activities that Radio Amateurs can get and should get involved in to unlock the next level of activities. It is said that amateur radio is the most exciting of all technical hobbies and the SARL will show you how you can enhance your experience while still having fun yet experience the thrill of achievement.

Programme Higlights

Setting the Scene

A keynote address by Lindsey Magnus of the SKA showcasing their hi-tech

Software defined radio -Showcasing how to use a simple dongle to turn your computing device into a full blow radio with practical demonstrations for HF and VHF applications.

DXing on the world’s first Geostationary Satellite “Is’hailsat 2” and how to build a ground station that will not break the bank.

A VHF reverse beacon network to alert when VHF openings occur – A RBN provides unique opportunity for real-time propagation awareness. The system will be demonstrated. Did you know that when VHF conditions are right, long distance VHF contacts can be made with relative simple equipment?

The SARL HF noise monitoring project and how you can save the future of DXing – it will not be the lack of Sunspot that inhibits, it will be the high and increasing noise level

Western Cape to St Helena on a two-metre vertical – how did it happen? What is the Westcoast propagation phenomena, does it occur elsewhere?

Plus, quick fire presentations (10 minutes) on a number of topic of interest such as Put a multi meter to better use, logbook of the world to your DXCC, SA latest  satellite from CPUT, XinaBox plug-in module to just about build anything, and many more.

There will be display of interesting hardware, and great prize to be won for just attending.

Book early, there are only 50 seats available at R250, after that registration will cost R700

Senegal, 6W. Elvira, IV3FSG will be active as 6W/IV3FSG from Thies, Senegal from 17 March to 14 April. QSL via Club Log's OQRS, LoTW or via IK3GES.

Togo, 5V. Members of the EI DX Group are active as 5V7EI until 26 March. Activity is on 160 to 10 meters using CW, SSB and various digital modes with five stations active.  QSL via M0OXO.

Uganda, 5X. Members of the Italian DXpedition Team are active as 5X3C until 25 March.  Activity is on the HF bands using CW, SSB and RTTY. They are active as 5X3E using FT8.  QSL direct to I2YSB.

DXCC News.  The following operation is approved for DXCC credit:  Tristan da Cunha and Gough Island, ZD9CW, the 2018 operation.

Proportion of Modes Used on the Air. "I've been running some reports on activity uploaded in logs up to the end of December last year", Club Log's Michael Wells, G7VJR posted to his blog on 10 March. "The total number of QSOs uploaded was quite high - more than any previous year - at 41,3 million QSOs. That's 12% higher than 2017 or 2016 (which were nearly identical at 36,8 million QSO each - and 2015 was 39,8 million). I think that fact is more significant given the ongoing decline of this particular solar cycle and it is possible evidence of extra activity from FT8 and newly-active amateurs who'd run out of steam on CW and SSB but are back to try digital modes". As for the operating habits, "in 2017, 8 000 Club Log users had uploaded at least one QSO with FT8. However, in 2018, that number has risen to 14 200. For comparison, 13 900 users uploaded at least one CW contact and 18 000 at least one phone (mainly SSB) contact. The total number of active users was just under 22 000 across all modes in 2018".

VHF+ UHF+ MICROWAVE NEWS - FOCUS ON VHF with ZS6YZ 17 March 2019

Focus on VHF and Above 17 March 2019

 Audio version

I received a question during the week regarding antenna gain versus feedline losses so I decided to share the answer with you as well. 

This is one of those questions that has the typical answer “that depends on...” 

There are definite advantages to raising the antenna height as high as possible. The general rule is the higher the antenna the better the performance. Aspects of this includes feed impedance, radiation diagram, radiation losses, distance from interference, reduction in possibility of exposure to RF radiation and the list goes on. A lot of these are HF related, but we are going to keep the answer to the VHF and above bands. 

How high do you go and what gains can you achieve versus what it costs to increase the height. 

With VHF and above, radio propagation tends to be more line of sight. 

The wavelength of the VHF and above frequencies are very short, and so the antenna does not need to be raised very high to minimise the ground effects so this is usually not a primary reason to increase the height of an antenna. 

You may want to increase the height of your antenna in order to clear some or other obstruction. Large trees and other structures will definitely absorb some of the signals at VHF and above frequencies. 

As a result of refraction, the radio horizon is in the region of 4/3 times the distance of the visible horizon. Raising the antenna will also increase your radio horizon and increase the range of your signal. 

The higher the antenna also means that the antenna is further away from sources of interference. This has advantages on receive as well as the transmit side where the transmitted signal may be a source of interference. 

The other advantage of height of an antenna could be the exposure to RF and the associated health risks with it. 

Now for some disadvantages. The higher the structure is that the antenna is mounted on, the more it costs to erect the structure. The steel required for the structure, the volume of cement required for the base that anchors the mast, the guy ropes required to stabilise the mast or tower and so forth. 

The higher the antenna is, the longer the feedline needs to be as well. 

Let’s talk numbers. Doing a simple line of sight calculation we will see that an antenna 10m high will give us a radio horizon of approximately 13 km. If we double the height, then we get a radio horizon of approx 18 km. We are only gaining a distance factor of 1.38 while we are increasing our height by a factor of 2. Increasing the height to 30m gives us a radio horizon of 22 km. We now have a distance factor of 1.7 versus a height factor of 3. Increasing the height to 40m we get a radio horizon of 26 km. A distance factor of 2 versus a height factor of 4. 

Put differently, in order to achieve a 2 times gain we need to increase our antenna height by at least 4 times. 

Now let us look at the losses of a typical coaxial cable. 

RG213 at a frequency of 145 MHz has a loss at 10m of 0.8 dB and at 40m a loss of 3.1 dB. We have just negated the gains we made by increasing the antenna height.

At a frequency of 435 MHz the loss at 10m is 1.4 dB and at 40m 5.7 dB. We are now going backwards. 

LMR400 at a frequency of 145 MHz has a loss at 10m of 0.6 dB and at 40m  2.4 dB. The antenna height has only just given us a slight advantage.

At a frequency of 435 MHz 10m gives a loss of 1.1 dB and 40m a loss of 4.2 dB. 

Sure we can minimise our losses using better coaxial cable, but we are paying more for the better coaxial cables. Add to this the additional costs to increase the height of the structure by a factor of four. We are not gaining much for a considerable increase in costs. 

It will cost less to rather use a Yagi antenna at 10m which will give you at least a 3 dB gain for a lot less costs. Now if you already have that 8 element Yagi giving you 11 dB gain, there is not much more that you can squeeze out of your setup. 

Well, that depends on how much money you have to spend on achieving a marginal increase in gain. The cost per dB gain now becomes very high.

At the last VHF/UHF workshop Dick ZS6BUN gave an excellent presentation on the Cost per dB where he looked at everything from the radios to amplifiers, the feedlines and the antennas. This is why these workshops should not be missed. 

The next VHF/UHF workshop is being planned for 25 May 2019 at the National Amateur Radio Centre. Put this date in your diaries and plan to be there. There is already one very interesting and controversial topic that is planned to be discussed. More about this later. 

Now for some VHF and above news. 

John ZS6JON sent me some pictures and a video clip of a contact he made on the QO-100 satellite from his garden. 

ZS6JON Garden Mobile Setup

 ZS6JON QSO 

John told me that he needed to go QRT as the heat of the sun was causing the crystal in his local oscillator to drift. 

John also sent me some photos of the other antennas in his garden 

ZS6JON 70cm 4.5m EME Dish

 

ZS6JON 23cm EME Dish

 

ZS6JON 2m EME Array

 

John also told me that he and Louisa ZS6LU will be in Gaborone over the long weekend of 21 March to prepare the logistics for the big 8 Band EME Expedition in October. They are taking 2m and 70cm equipment with them and hope to make some ZS contacts while they are there. So all the long distance VHF/UHF guys need to point your antennas to Gaborone and see if you can make contact with John and Louisa.

 

The 46 Group had some good comms this week especially on Friday morning.

 

All those that did not attend the AMSAT SA Symposium yesterday missed out on another great and informative day of learning. I came away with many notes of things to follow up on and look forward to the next one.

 

The next meeting of the VHF Work Group will be via Skype on 28 March 2019. If you want to join the VHF Work Group, send us your Skype name to vhfnews@sarl.org.za and we will add you to the call.

Focus on VHF and Above 10 March 2019 

Audio version here 

The most creative of amateurs must surely be those who homebrew and build things for themselves. 

They have that ability to look at something and see a use for it in a completely different application for what the manufacturer originally intended it for. 

For example, you go to the local plumbing supplier ask them for various plastic and copper fittings. You have in your mind a new antenna with the plastic fittings acting as insulators and the copper fittings are there to attach the 15mm copper pipes for the antenna elements. They have in their minds a water pipe and cannot understand why you need specific fittings. 

I have also come across numerous amateurs who do not want to try and build something for themselves. They are always asking someone else to do something for them. They will for example not want to solder because they say they cannot solder, but they do not try either. The more you practice the easier it will become. 

Listen to Onno VK6FLAB’s podcast “Creativity comes with practice” 

As Onno says this comes with practice and don't be afraid of failing, the more you fail, the better you learn. 

Here is some news about the VHF and Above bands. 

As we broadcast this program, the SARL VHF/UHF Analogue competition is drawing to a close. This whole week the guys of the 46 Long Distance Group have been preparing for the competition and on Saturday morning they were testing their stations and making sure that they are getting out from the various sites that they had selected. Here is an audio clip recorded by Carl ZS6CBQ of Willem ZS6WAB testing from the Soutpansberg Club competition station ZS6SPB on Ysterberg in Limpopo Province. 

Audio Clip ZS6SPB Test on 70cm 

During the past week the Hepburn charts predicted that Wednesday there would be marginal Tropoducting stretching into the interior of the country and from the reports on WhatsApp, the 46 Long Distance group also experienced good conditions. 

 

 

Picture of Hepburn Chart for Wed 6 March 2019 

Carl ZS6CBQ reported hearing the Bloemfontein beacon S7 and Koos  ZS6KSG also recorded hearing Rickus ZS4A at a S8. So keep your eyes on the charts and remember to record the weather data as well. 

Peter ZS2ABF reports from East London “Hi all,as usual Dave ZS5DJ and myself came on frequency last Monday evening. Conditions were poor along the South East Coast, but we had a QSO and chatted away. No breakers were heard.

Last night Wednesday 6th, the predicted conditions looked excellent for our coastal area. I informed Dave to come up via Email and awaited our allotted hour. It was just my luck that at about 16:30 hrs the sky darkened,and it started to rumble. By the time 20:00 came we were in the middle of a violent thunder and lightening storm. I took a chance and called Dave. He came straight back and said I was 5:5 to him.Unfortunately the storm crashes and bangs were load and dangerous. We said hello, and I had to pull the plug to stay alive. What a pity as the conditions were so good.” 

We last reported that Raoul ZS1C used Leon Korki ZS1MM’s station to make some CW contacts over the Es’hail2 satellite. Well, RaouI has now set up his own homebrew station and worked the satellite with only 125mW, Raoul writes on the SARL Forum, “I got into the satellite last night with 125mW, today added another stage,and now have 28dBm (630 mW) output on 2.4 GHz. I worked some ssb for the first time as well.” 

Raoul’s configuration is an ADF4351 Synthesiser followed by two RF3374 amplifier stages, then a level 13 mixer stage using an ADE-25MH device. After the mixer is a cavity bandpass filter, another RF3374 amplifier and another cavity filter. Raoul says that this configuration provides a clean signal on the output. The output is then fed into two RF2126 amplifiers in series. The modulation signal is provided by a FT817 set to minimum power of 230 mW on 70cm and further attenuated to 13dBm by a 50 Ohm Pi attenuator. The signal is then fed into the mixer. The ADF4351 Synthesiser is programmed by an Arduino Uno. 

Well done Raoul. This is what makes amateur radio a super exciting and rewarding hobby. There is no greater satisfaction than building something yourself and being able to complete a QSO with your masterpiece.

You do not need to have a large signal to work the Es’hail satellite. On Southgate ARC news I found this report of a 2.5 milliwatt OPERA signal via Es'hail-2. 

Markus Vester DF6NM successfully used the digital mode OPERA to send a 2.5 milliwatt signal through the 2.4 to 10 GHz amateur radio transponder on the Es'hail-2 / QO-100 geostationary satellite. Graham G0NBD writes about the contact on Digital Radio Groupsio.

On March 3, 2019, Markus started using 250 milliwatts of OPERA on 2.4 GHz into a 60 cm dish pointing at Es'hail-2. The downlink signal was received via the AMSAT-UK and BATC 10 GHz WebSDR at Goonhilly in Cornwall by Peter Knol PA1SDB.

Markus then reduced power to just 2.5 milliwatts and the signal was still receiveable. See Digital Radio Groupsio post at
https://digitalradio.groups.io/g/main/message/50861

OPERA was developed by Jose EA5HVK and can be downloaded from
https://rosmodem.wordpress.com

Why not go over to the Qatar OSCAR-100 web receiver at

https://amsat-uk.org/2019/02/10/qatar-oscar-100-web-receiver-now-live/

and listen to some of the QSOs taking place. 

For those guys that love playing with their Raspberry Pi devices be sure to download the next issue of the MagPi magazine. 

RaspberryPi magazine MagPi will feature articles on Amateur Radio Projects in issue 80, available for free download from March 28 from https://www.raspberrypi.org/magpi/  

Well that is all the VHF and Above news for this week.  

The next workshop that will be held is the AMSAT SA Space Symposium on 16 March. Make sure that you do not miss out on all the interesting projects and presentations that will be shared with us.  

The next meeting of the VHF Work Group will be via Skype on 28 March 2019. If you want to join the VHF Work Group, send us your Skype name to vhfnews@sarl.org.za and we will add you to the call.

What is Amateur Radio ? 

Tell me more  about Amateur Radio

Radio Amateurs, or "Hams" use two-way radio communication to make contact with other radio amateurs all over the world. They are even able to use satellites and on occasion speak with astronauts. Radio Hams can do this from home or while mobile in cars, boats or on foot.

Radio Hams have a full range or communication modes at their disposal. These include plain voice, Morse code, numerous digital computer modes and even graphical modes like television. As a licensed amateur radio operator you will be able to join in experiments using all these modes.

A
mateur radio can be enjoyed by young and old, male and female, even the most severely disabled can make friends around the world from their own home. This hobby knows no boundaries.
