Signals from Space with a Handheld

September 22, 2023 By: Chris G3YHF Category: Club, Fun, News, Training

The ISS (international space station)’s digipeater can be heard with a 2 meter handheld when one of the ISS passes is overhead.
 
And if you can connect your 2m FM rig to a computer, you can send and receive messages through it – and receive the special ISS QSL card!
 
Now is a good time to try as the ISS is passing over the UK at a good elevation twice most early evenings.
 
Find the ISS pass times HERE – remember to add 1 hour as times are UTC.  Ideally, look for 70° or 80° elevation when ISS is passing close to overhead.
 
The live ISS locator is useful to track its position and digipeater footprint.
 
Tune to 145.825 FM with squelch OFF and listen for the short bursts of data.  You will only hear these for a couple of minutes during each pass.

The contents of data packages received by the ISS are instantaneously retransmitted by the digipeater and received by one of the SATGATEs where they are automatically uploaded to the ARISS web site HERE along with the list of stations whose transmissions were received and maps of their locations.
 
Only short messages can be sent, and here are some examples from earlier this evening:
 
00:00:01:12 : G0GOO]CQ,RS0ISS*,qAR,ED1ZBF-3::G7HCE :QSL and 73 via ISS
00:00:01:32 : G6UQZ-1]APDW17,RS0ISS*,qAU,DO6DD-10:!5204.75N/00034.94EyPHG200073 de Andy in Clare, Suffolk
00:00:01:39 : G3YHF]CQ,RS0ISS*,qAU,DO6DD-10:=5226.15N/00152.30W-IO92BK 73 de Wythall RC {UISS54}
00:00:01:41 : RS0ISS]0P0PS3,APRSAT,qAR,ED1ZBF-3:’v&l SI]ARISS-International Space Station=
00:00:01:42 : G7HCE]APK004,RS0ISS*,qAR,F1ZRP-3::G0GOO :Copy 59{5
 
The highlighted message is the one I sent this evening that was received and retransmitted by the digipeater after 6 or 7 attempts!
 
It gives the age of the retransmission, my call, the callsign of the digipeater – RS0ISS* is the Russian ISS call sign, DO6DD is the German SATGATE station that received and uploaded the packet to the ARISS site, and then there is my message: my APRS location in lat and long and Maidenhead square, and a few words of greeting!  The ‘ – ‘  instructs the ARISS site to add my QTH to its map.
 
Occasionally, the digipeater is temporarily shut-down for spacecraft operational activity like a spacewalk.
 
To send a message through the digipeater, connect a rig that can transmit 2m FM to a computer.  The rig will need an internal soundcard or if not use an interface like Signalink.  
 
I use my Yaesu FT7800 mobile rig on 5 watts with Signalink and a collinear. 
 
I also have an old Kenwood TH-D7 handheld with internal TNC and APRS functionality – this puts out 2.5 watts and I’ve been received by the digipeater again using my collinear.
 
Then download and configure UISS , which has been designed for communicating with the ISS digipeater.  Configure so it talks to your radio.  Then set ‘path’ to ARISS and add your APRS data and a short text.
 
There’s lots of on-line advice on how to set up UISS and use it to send a message – e.g.  on the AMSAT site
 
DON’T USE HIGH POWER!  ISS is line of sight, so 5 watts to a collinear will work very well.  High power will put exessive demand on the ISS rig’s batteries and block other stations from using the digipeater. 
 
The digipeater is simplex and lots of European stations will be calling so it may take several goes to get through.  On the current west to east trajectory of ISS, it’s best to try early on a pass before it’s in range of continental Europe
When your message is retransmitted by the digipeater, it will often appear as a highlighted message in UISS.
 
However, you may not receive this retransmit due to fading or other factors causing even one bit of data to be lost, so affecting the checksum.  
 
So it is always best to search for your call on the ‘Amateur Radio Stations heard via ISS’ page at ariss.net as a ground station operating a SATGATE may have received the retransmission and automatically uploaded it to the ARISS site.
 
Wythall Radio Club members had a go with conducting a brief QSO using the digipeater a couple of years ago, and two of us used it to score points in our Christmas Contest.  
 
Have fun!
 
 
 

Fun in The Sun in the Park Part 3: The Radio Club’s ‘Plug and Play, Day in Wythall Park

September 20, 2023 By: john daws Category: Club

Our previous two reports described our  visitors’ interest shown in Neil’s and Ian’s  satellite and digital operations respectively.

Our final reports reflect the successes of  Lee ( GoMTN ), Chris (G3YHF ) and John (M6KET) on the HF bands using SSB and CW.

Chris working Canada on 20m SSB

The Lab 599 TX500 lightweight all band all mode transceiver+LIFEPo battery

 

Chris (pictured right) brought along his rig-in-a-rucksack ( previously spotted on the summit of Bredon Hill)…The Lab 599 TX500 lightweight all mode transceiver and a LiFEpo battery along with a homebrew 20m delta loop on a 7m telescopic pole.

 

Chris reports:  “tuning on 20m SSB the Worked All Europe Contest produced some strong signals and I worked VE3AJ in Canada first call-not bad for 10 watts!!” Lee G0MTN also worked Canada on the same rig whilst John M6KET borrowed Phil’s operating table and Portable  HF dipole and worked a number of Spanish stations on 20m  with 5 watts CW and his KX3.

By 2.30 many were beginning to wilt in the heat and it was time to pack up, lower the gazebos  and return  the equipment  to our nearby store. Chris writes: “Like all Plug and Plays I found the social side as much fun as seeing other Club members’ gear. and operating portable is always enjoyable.”

This was a great opportunity to showcase the Club and the diversity of Amateur radio; I think our visitors were genuinely interested in our operations and I include some of  visitor Martin’s comments below 

“A shared passion that unites the member… the welcoming nature of those present….the enthusiasm and thrill of connecting with fellow operators across continents….a celebration of a shared love for amateur radio… warm hospitality.”

A big thank you to Club member Martin G8VXX for providing the generator; this entailed a one hour round trip to deliver and collect and a big thank you to Phil 2E0WTH and Peter M5DUO for helping the day run so smoothly. Phil and Peter’s experiences in field operations continue to be invaluable to the club.

Phil, 2E0WTH dispenses some wisdom to an attentive chairman before providing this scribe with an outstanding sausage sandwich. Thank you Phil !!  

Among the visitors, members and operators recorded were: Chris G3YHF, Phil 2E0WTH, Peter M5DUO, Lee G0MTN, John M6KET, Ian M0LQY, Don G0NES, Winston 2E0EGP, Martin G8VXX, Neil G1TZC, Debra SWL, Mike G4VPD and Chris G7DDN.  (Apologies if I missed anyone.)

Fun in the Sun in the Park Part 2: The Satellite Connection

September 14, 2023 By: john daws Category: Club

Neil contemplates the radio world through the medium of Satellite QO-100

The next episode features Neil G1TZC who attended his first Wythall Radio Club ‘Plug and Play’ last Saturday and despite the very hot conditions calmly erected  the gazebo, installed the satellite dish and wasted no time in attracting a captive audience as he introduced them to QO -100 communicating with amateur radio stations through the use of satellite. His report on the day follows:

“For my part the Plug and Play event was important on so many levels. Apart from visiting the new members night on the previous Tuesdays, all of my interaction with members had been over the air or via the internet group, so it was great to meet people in the arena of an organised event. It was also a chance to test the portable satellite setup in the real world with various changes and repairs that had been made. Once everyone had arrived and things started to get going, something struck me straight away. Debra and I were made to feel like we had always been members of the club.

It was great to see everyone help everyone else, something that can often be missing from clubs. Often people turn up with the expectation that it will just appear, but not at the Wythall club. People pitched in and helped each other. Four people do a gazebo and erect a mast. People going back and forth between stations to help where needed.

As for the satellite station it was nice to have such an interest from the visitors to the site

Neil’s commentary and operations soon attracted an  audience,  including our very own 2E0EGP

 

     

Equipment did struggle with the heat but we made a few contacts, but that actually ended up being somewhat secondary. I felt I spent more time talking and explaining how QO-100 differed from other amateur satellites. There was a keen interest in the fact that geostationary operation still kept roots in traditional forms of communication, such as CW and SSB as well as embracing a whole range of digital modes. Also pointing people in the direction of internet resources via the printed sheets in the satellite tent. Several people were pleased that the QR codes were on the bottom of some resources for them to take the pages with them for later reading.

 

The fact that the system also has an emergency frequency that covers half the planet was explained with the practical example of the earthquakes in Turkey and how the amateurs were able to pass information from the disaster areas to major cities via the satellite without having to worry about any propagation issue. As far as contacts, we had contacts with Finland, India and St Helena Island.

All in all a very positive even and I would be delighted to participate again at any further events.”

Fun in the Sun in the Park-1

September 11, 2023 By: john daws Category: Club

Dressed for the occasion and the sweltering heat  the hardy members of Wythall Radio Club took to the great outdoors at Wythall Park on Saturday and operated G4WAC/P in all its various  modes: Digimode, Satellite, CW, SSB and VHF.

                            The operating site in Wythall Park on a sunny Saturday

In this first instalment Ian M0LQY, operating digimode takes us through his thoughts on the experience.

“What a glorious day was had by all at our field day with the weather being perfect and lots of people dropping in to see a real range of radios and operating methods great stuff. For me I wanted to try out a few things a new antenna which I purchased last year and was waiting for the right opportunity and in particular a project I had been working on for a while to use a specially built operating system for my raspberry pi. The experience of using it in the field for my favourite digital modes was informative and a real lesson in what I got right and more importantly what was not.”

                 Ian cheerfully going about setting up on Saturday

“My aim was to have a working setup that I could use portably contained within a single carrying case. Back at the shack I set about building both the 32 bit and 64 bit versions of the raspberry pi operating systems from source rather than using prebuilt binaries. Having had a number of Raspberry Pi’s I find that building the software from source produces better performance and stability. Therefore, I decided to do everything that way to produce a bespoke purpose-built Pi that suited me and my exact requirements.”

“So how did it go? Like all things it was a mixed bag with the main aims achieved but unexpected niggles and self-inflicted incompetence’s  all conspiring to make the day interesting. My requirements for the Pi were as follows:

Only have the software loaded that I would actually use. Mostly, digital mode applications. Logbook and other useful Amateur Radio programs.

  1. Be able to operate without a monitor (Headless).
  2. Remote operation from another computer, tablet or even a mobile phone.
  3. Have automatic availability of my home NAS shares with read and write capability in both directions. Any Connection must be able to pass username and password , so no guest access.
  4. Ability to use the programs installed with two Radios (Yaesu FT991A and Xiegu X6100) both of which have USB CAT control and built in sound cards”

“Having spent time building the operating systems at home and getting the radios to talk to the pi with audio, CAT control it was all working well. So the field day was the ideal chance to test out the antenna a 80-10 40 metre EFLW from UKAntennas which was supposedly to work on all of the bands and did not require an ATU. Also, I could test the pi setup with the bare minimum before choosing a suitable carrying case with foam inserts.”

 Ian goes on to detail some of the problems on the day: the voltage  and an issue synchronising the clock to the NTP server  (no internet connection in the field) and a full account of the challenges and solutions  can be read on Saturday’s posting on the Repeater

“As for the antenna, well it works and does indeed allow operation on all of the advertised bands without an ATU. My issue is that I like to operate with low SWR and at 40M it was showing 1:1 as I went to higher bands the SWR crept up and on 17M reached 2:2 although that was with 50 watts at 20 watts my normal operating power this became 1:9. So yes it works and was surprisingly quiet although the location must have helped.”

Free radio demo this Saturday!

September 06, 2023 By: Chris G3YHF Category: Club, Fun, News

Visitors welcome at Wythall Radio Club’s free demo of short-wave and VHF radio communication, on Saturday 9th Sept. between 10 and 3.

We’ll once again be operating various radios from Wythall Park, using a variety of antennas – and hopefully we’ll have some contacts via a satellite!

You can find us on the far side of Wythall Park, furthest from the car park. 

Follow the tarmac footpath on the right hand side of the small playground, and keep going bearing right at any junction!

You’ll see vehicles, antenna masts and flags – that’s where we are. 

Here’s a report on a recent radio field-day in Wythall park.

Neil’s G1TZC Canadian Adventure

September 02, 2023 By: chris pettitt Category: Club, Fun, News

Neil operating in IARU HF World Championship weekend 11/7/20

Our resident satellite member, Neil G1TZC, amused us all recently with a tale from his past on the club’s group.io forum with a tale about a visit to Canada. We thought this would make good first addition to our Articles’ section in the Library folder on the club’s website.  READ IT HERE 

 

 

 

Enjoy!

 

 

Listen to radio amateurs without a radio!

August 24, 2023 By: Chris G3YHF Category: Club, Fun, News, Training

Thanks to the internet, it’s possible to listen on amateur radio frequencies without a special short wave receiver.

There are many WebSDR (Software-Defined Radio) receivers connected to the internet, allowing multiple users to listen simultaneously.  

A list of WebSDR receivers and links to them is at  http://www.websdr.org/   

To use WebSDR…

  1. Navigate to a receiver like Hack Green, Cheshire (one of the closest WebSDRs to Birmingham) or KFS WebSDR in California (where you can listen in to the US amateurs).
  2. Once on a WebSDR site, enable ‘allow keyboard’, which permits you to tune the receiver using mouse wheel or keyboard arrows.
  3. You may have to enable audio settings on your browser – see the advice on each webSDR site; eg for listening to Hack Green using Chrome: Click the Lock in the address bar of your Chrome browser. Click Site Settings. Under Sound, select Allow.
  4. Select the band you want to listen on – you will find most stations on 80, 40 and 20 meters, in the frequency ranges in the table below.
  5. When listening on 80 and 40 meters, select LSB (lower side band); when listening on 20 meters, select USB (upper side band).
  6. Once you hear a station, it may sound like ‘Donald Duck’ – tune slowly and the voices will become clear
  7. Once you become proficient at tuning in stations, try some of the other receiver functions – e.g. narrow IF bandwidth and IF passband can be used to reduce interference.

Over the next few months, you can expect the following radio conditions:

Amateur band

(meters)

For SSB (voice) tune these frequencies and select LSB or USB as indicated Expected coverage if listening to Hack Green

(More detail on propogation predictions here)

 

80m 3700-3800 LSB Daytime – UK; Evening – UK and continental Europe
40m 7100-7200 LSB Daytime – continental Europe (sometimes UK); Evening – Europe, and occasionally further afield
20m 14150-14300 USB Daytime – Europe; Evening – Europe and often further afield

CALL SIGNS

You can identify the countries from which stations are operating by comparing their call sign prefix (the first one or two letters/numbers) with those on the list of international call sign prefixes e.g. the Wythall Radio Club call sign is G4WAC – G means the station is in England. 

 

 

Q CODES AND OTHER SHORTHAND YOU MAY HEAR

You may hear the following…

CQ, CQ – I am calling for a contact; please reply to me

DX – long distance (normally, outside the operator’s continent)

QRZ? – is anyone there?

QTH – location of the station

QRM – interference on the signal

QSB – fading on the signal

QSL – confirmation of the contact or information passed

73s – best wishes and goodbye

GAINING AN AMATEUR RADIO LICENCE

The ‘Foundation licence’ is not difficult to obtain.  There is some simple electronics and radio operating to study.  You can find details of the licence levels and courses on the Wythall Radio Club web site and there is more information at the RSGB.

 

Come and meet us!

So close but just pipped at the post! G4WAC/P (GoMTN) runner up in the NFD CW QRP Class

June 24, 2023 By: john daws Category: Club, Contest, News

Was the break for sustenance (a sausage roll?) the crucial lost few minutes  the moment that Lee (G0MTN) just lost out to M0RYB/P  (Loxlot Club) in the QRP Unassisted Portable Station Section in the recent National Field Day Contest??

Lee endured extremes of heat and cold in his one man 24 hour operation

Lee writes:

“NFD results are out and  G4WAC/P *almost* won the QRP shield… I came second. I had more QSOs than the second placed entrant (and previous winner) but couldn’t find / work enough multipliers.  All the Russians that called are worth zero points too currently. Have a look at the attached chart to show how close the race was. It does show there’s no time for sleeping!  

 

 

I submitted the log to the German DARC society for their (and the IARU) Field Day – let’s see if it’s the same result there.

A magnificent performance  and please see the previous report on Lee’s extraordinary marathon

Wythall Radio Club on the Road (or on the Buses) GB0BUS

June 20, 2023 By: john daws Category: Club

Chris and Lee on the TS590 HF station operating CW and SSB

Last weekend was the occasion of the International Museums on the Air  Weekend and WRC rose to the challenge magnificently activating  The Wythall Transport Museum and operating  three stations   as London Routemaster buses , Vintage Morris Vans and curious visitors  wandered past our site.

The special callsign of GB0BUS had been assigned to us for the occasion

Under the protection of 3 gazebos (assembled the day before in Chris G3YHF  logistical masterplan) the Club operated an HF station (the Club’s TS590 on HF- voice and CW- 40/20 and 15 metres on the OFCD) and  a K3  providing  digital  contacts on a 17 metre flat top dipole. Les 2E0LRV provided the VHF coverage from his well-equipped Landrover

Phil takes questions on how the ‘Easy -Up’ Gazebo got its name

The dipole and OFCD were positioned the day before with the aid of Dave’s  (G3YXM) magical catapult and open faced fishing reel (a real art of casting this!) and although short of room in our operating corner the two  HF antennas eventually performed well despite some initial inter- antenna reaction!! 

In all some 49 stations were worked including: Cyprus, Isle of Man, Canada, USA (Texas), Kazahkstan, Iceland and many similarly minded Museums on the Air stations listed below:

In all some 20 separate DXCC  countries were worked and the following Special Event stations

YQ0RN Radionostalgia – Brusturi- GB2ST Standedge Tunnel -GB2KDR Keith and Dufftown Heritage Railway Museum- GB1MHM Moseley Heritage Museum  (not our Moseley) GB2SPY wasn’t in the official list but is a museum special event- GX3EFX The Forties Experience- GB2CPM Amberley Museum- GB0MFM Moira Furnace Museum-MX0WGS Wings Museum-GB0WFX (not Museum, but 110th anniversary of Northampton Club)- GB2RRM Ramsey Rural Museum- GB2ST Standedge Tunnel- GB0MMH (not Museum but Men’s Mental Health special event.)

50 QSOs  were made on SSB / CW/FT8 (49 different stations – one station called us a second time after an earlier QSO.)

Les’ trademark Land Rover and self contained VHF station

 The Assembly and operating team for the event were Chris G3YHF, Ian M0LQY (digital and console operator!), Roger M0GWM (main and invaluable logistic haulier), John M6KET, Phil 2E0WTH, Les 2E0LRV, Lee G0MTN and Dave G3YXM for his invaluable help in getting the antennas hoisted.
 
Visitors to the site during the day  included Mike G4PVD, and a number of lapsed licence holders who were hopefully inspired to revisit the hobby.
 
Would we do it again? .. yes it was an excellent opportunity to showcase amateur radio, show our enthusiasm for the hobby,  and get out and about in the community:  a really good Club  and team event .

Just look at the reach of Ian’s FT8 signal

Ian M0LQY and  visitor Richard view the world through F T8 on 17 metres
