CW

Since Christmas I have been attempting (again) to learn CW. There are plenty of people to whom this comes naturally. I, on the other hand, had a promising career as a CW radio operator cut short by a tragic lack of talent (to steal someone else’s joke).

So, why bother? Well to be honest I quite like the simplicity, portability and cost of rigs that focus on CW. As the price and complexity of rigs increase it moves me to reduce my interest in this exotica. So to keep the hobby alive in my shack and to carry on learning about RF I thought it’d be nice to try some new stuff out. I can use what I have as a base (Icom IC-7000) and get out and about for UKAC VHF contests when I fancy it. But CW was always a bit of a step beyond me.

I’ve used a bunch of resources to help but by far the most useful was hooking up with a group on twitter called @lids_cw. Along with the plethora of software the encouragement from them has been excellent. What I have found out is that my sending has improved no end by getting on air but my receiving is stubbornly refusing to come together. Practice make perfect. The Goal for me is a Morse proficiency test at the Norbreck rally next year. Hopefully at 15wpm

April Radio Antics

It has been an extremely busy month since my last post, sadly not all of it radio related.

During the Easter holiday I was away in the caravan at a dog agility show in North Yorkshire, camping in the grounds of Duncombe Park just outside Helmsley. When not competing I was able to find some time to operate.

Boris combining both hobbies!

Using just an M0CVO Magitenna I had some reasonable low power SSB operation on a number of bands and activated a square for the Worked All Britain Award (WAB) (SE58) and gave some points away during the Polish SP DX Contest.

The WAB scheme was something I signed up for last year when I went to Skye but haven't participated till now. The WAB net on 7.160MHz is a little daunting to listen too but once I jumped in it was relatively painless to activate the square and I plan to do some more when I go back to the Isle of Skye and Islay later this year, but I must improve my portable HF antenna.

Over the weekend of the 11/12th April there was another SSTV activation from the ISS in celebration of Yuri Gargarin's life. I had some good results decoding images and decided that I'd use it as a way to promote South Kesteven ARS locally and contacted the local newspaper.

The Newark Advertiser did indeed feature the story both in print and on their website and they were very good in mentioning the radio society. It was also printed in the sister free paper.

It was nice to get some very complimentary reaction to my publicity drive in social media and other websites including an article on the Amsat-UK page http://amsat-uk.org/2015/04/15/iss-sstv-in-the-press/



Last weekend I and other members of the South Kesteven Amateur Radio Society operated the special event station GB5ROC at the Buckminster Cold War Royal Observer Corps (ROC) Nuclear Bunker Open Day.

Situated on the Lincolnshire/Leicestershire border ROC Post Number 62 is leased to the UP AN’ AT EM! History project and has been restored as a museum and is managed by ​​​Jed Jaggard. The free open day was a rare chance to visit and experience an important part of British post-war history.

These bunkers are underground structures found all over the United Kingdom, constructed as a result of the Corps’ civil defence nuclear reporting role and were operated by volunteers during the Cold War between 1955 and 1991. There was a network of over 1500 such monitoring posts around the UK designed to detect nuclear detonations and monitor blast and subsequent fallout and radiation levels should an attack take place.

Thankfully they were never used and the last of the posts were closed in 1991 when the majority of the ROC was stood down following the break-up of the Communist Bloc. Many have been demolished, fill in or adapted to other uses but the majority still exist, although in a derelict condition.

During the open day visitors had the chance to climb down into the bunker so for reasons of practicality SKARS operated GB5ROC from a tent close to the bunker hatch.



Along with Stewart Mason (M0SDM) and Sean Burton (2E0ENN) we operated on 40m from 10:00 till 16:30 BST and made a total of 151 contacts mostly UK operators with a number of European stations.

Equipment was supplied by Stewart who did the majority of the operating and consisted of a Yaesu FT-897D at 100W feeding an off centre fed dipole at around 30ft on top of a Racal push up mast. Stewart also provided a new club banner.

The open day was very well attended and a number of local and not so local amateurs (one visitor from Australia VK4UA ) came along thanks to the publicity the event had received on Facebook, Twitter, GB2RS and the Southgate ARC newsfeed. It was great to meet up and chat.

Encouragingly members of the general public were keen to learn what amateur radio was all about and they were able to take away a number of leaflets with information about the hobby and contact details for SKARS.




It was an excellent day all round with the operators have a fun time and gaining useful experience of operating a pile-up. The weather was kind with blue skies and sunshine. Hopefully it will become a regular activation at future bunker activations.

The video below Stewart operating Richard M6GPT who had tried most of the day to make contact and was successful just before the station was closed down.



SKARS member Mark (M0OBL) had monitored GB5ROC and made a video of his Elecraft K2 receiving us load and clear.



Next month is going to be very busy as I have GB2EGG and the Eggsplorer-1 HAB flight to organise and that too has made the press. http://www.sleafordtarget.co.uk/Egg-sent-space-World-Egg-Throwing-Championships/story-26372439-detail/story.html

Oh and lastly remember this is the original "Radio Antics" blog, often imitated but never bettered.. 73

Update, the visit of VK4UA to GB5ROC wasn't due to any publicity or advertising - it was simply because Stewart had his van parked on the verge with his callsign clearly visible and he was visiting the area - the simplest ideas are the best it seems!




Hams doing what they do best

These articles are from the ARRL Website:

4/27/2015
As the death toll climbs in the wake of the devastating magnitude 7.9 earthquake in Nepal, rescue and recovery work is continuing, and Amateur Radio volunteers have been a part of it. The earthquake — said to be the worst in Nepal in 80 years — hit an area between the capital city of Kathmandu and the city of Pokhara. An emergency net had been running around the clock on 20 meters with Jayu Bhide, VU2JAU, as net control station and other stations in India participating. Bhide is the Amateur Radio Society of India National Coordinator for Disaster Communication.

The Nepal disaster has claimed more than 3200 lives and wreaked widespread damage. Many others are missing or have been injured. Hospitals have been flooded with those who suffered serious injuries in the earthquake. Persistent aftershocks continue to terrorize those who managed to escape harm. On Mount Everest an avalanche devastated base camp, and at least 100 climbers were stranded on the mountain. Several mountaineers were reported among the dead.

Hams in India have been among the most active responders. Parts of eastern India also suffered earthquake damage. Within Nepal, members of the Nepal Amateur Radio Society are reported to be active on HF emergency nets as well as on VHF/UHF to handle local traffic.

“The situation in Nepal is getting worse, as tremors continue to strike every hour at a magnitude of 4.7,” Bhide said. The government of Nepal has asked all people to stay out of buildings, as damage is expected to increase. Due to the conditions, emergency communication with 9N1 stations came to a standstill; no communication was possible overnight as the earthquake demolished the building where emergency communication gear was installed.”

He said Satish Kharel, 9N1AA, and his daughter Tej, 9N1DX, were able to return to the air this morning. Both are in Kathmandu. 9N1AA has said he’s operating low power with the help of solar power and coordinating with the Nepal police in Kathmandu. Suresh Upreti, 9N1HA, has been assisting with emergency communication as well. Internet service has been spotty in Nepal at best. So far, there has been no cross-border movement of either radio equipment and radio amateurs.

Sanjeeb Panday, 9N1SP, has indicated that he will be on 21.360 MHz at 1645 UTC, and radio amateurs not involved in the disaster response should avoid this frequency. 9N1SP has intermittent Internet service. He has said that propagation on 20 meters, where an initial emergency net was established was poor, but he has been in contact on 15 meters with Tim McFadden, KB2RLB/T6TM, a Military Auxiliary Radio System (MARS) member in Afghanistan.

Ironically, McFadden, Kharel, Panday, and others took part in MARS exercises in 2013 and 2014 in which the emergency scenario was an earthquake in Nepal. Army MARS Program Officer Paul English, WD8DBY, said the response to this earthquake followed the procedures trained during those earlier exercises. McFadden had been scanning International Amateur Radio Union (IARU) Global Emergency Center of Activity (GECOA) frequencies for stations in Nepal. GECOA frequencies were established as places to pass emergency traffic. Worldwide GECOA frequencies are 21.360 MHz, 18.160 MHz, 14.300 MHz, 7.240 MHz, 7.060 MHz, 3.985 MHz, and 3.750 MHz.

Nepal’s first Amateur Radio repeater, set up in 2012 by the National Society for Earthquake Technology (NSET), and at least a dozen ham in various locations were reported on VHF. The 9N1KS repeater (434.500 MHz in/145.000 MHz out) is on the NSET headquarters building on the outskirts of Kathmandu. A drill conducted in 2012 indicated good coverage of the Kathmandu Valley.

The US chapter of the Computer Association of Nepal provided technical and financial assistance for the repeater and supplied equipment to use it. The repeater has a battery back-up power source.

The NGO “Humanity Road” is maintaining an updated summary of damage as well as of immediate needs.

“Hams from India and other countries have set an example to provide essential communication during disasters,” Bhida said. “The coordination and cooperation have also demonstrated [there is] one world, one language.” — Thanks to Jayu Bhide, VU2JAU; Jim Linton, VK3PC; Tim McFadden, T6TM; Lloyd Colston, KC5FM; US Army MARS, and others

Hams in Nepal, already in limited supply, continue to turn out to aid in the ongoing recovery from the April 25 earthquake that struck the Himalayan nation. Radio amateurs in neighboring India are also pitching in, and at least two groups of hams from Gujarat, India, are planning to travel to Nepal and set up stations “at critical places,” said Amateur Radio Society of India (ARSI) National Disaster Coordinator Jayu Bhide, VU2JAU. He is planning to set up HF and VHF stations at Gorakhpur, on the India-Nepal border. Joining him will be Ananda Majumdar, VU2AGJ, and Sandip Baruah, VU2MUE.

 "Nepal hams are facing a hard situation,” said Bhide, who has been among the net control stations for an HF net initiated in the wake of the disaster.

The Indian hams traveling to Nepal may not be permitted to operate once they arrive, however. In an e-mail to members, ARSI President Gopal Madhavan, VU2GMN, said that Satish Kharel, 9N1AA, confirmed that “individual operators from other countries are not permitted to operate in Nepal, even during the emergency, unless they are part of a government team.” Madhavan said he was issuing the alert for the benefit of anyone planning to cross into Nepal from India and operate there.

Bhide said more Nepalese hams not formerly involved with the disaster response have since joined their Amateur Radio colleagues to volunteer communication support.

One major effort on the part of rescue teams is attempting to locate the missing, as well as to recover quake victims buried beneath debris. More than 4000 people died as a result of the earthquake and subsequent aftershocks. The disaster also has stranded many people, as roads were cut off by landslides and damage.

Earlier today, Sanjeeb Panday, 9N1SP, received support from three other Nepalese Amateur Radio operators — Ajay Bhattarai, 9N1AJ; Aayush Kumar Chaudhary, 9N1AY, and Sudarshan Sharma, 9N1SH. “Dr Sanjeeb and his team continue to operate HF radio out of a local University in Kathmandu, according to a report forwarded to ARRL by Army MARS Director of Operations Paul English, WD8DBY. “Dr Panday and his team were able to send HF radio slow-scan images of the disaster via Amateur Radio to the Army MARS operator in Afghanistan,” English said. The images subsequently were posted to the US Pacific Command response coordination portal, APAN. Tim McFadden, KB2RLB/T6TM, a Military Auxiliary Radio System (MARS) member in Afghanistan, has been monitoring the emergency traffic. Ironically, McFadden, Kharel, Panday, and others took part in MARS exercises in 2013 and 2014 in which the emergency scenario was an earthquake in Nepal. English said the response to this earthquake followed the procedures used for training during those earlier exercises.

The earthquake — said to be the worst in Nepal in 80 years — hit an area between the capital city of Kathmandu and the city of Pokhara. An emergency net has been running around the clock on HF. Members of the Nepal Amateur Radio Society were reported to be active on HF emergency nets as well as on VHF/UHF to handle local traffic.

And then there's this from the Free Press Journal:

307 from Maha rescued


Mumbai : After the conventional mode of communication like mobile and telephone systems broke down in Nepal, the state Disaster Management cell has dusted off their HAM radio sets, a 19th century communication device which is famous for its long range and network.
 
Additional Resident Commissioner, Maharashtra Sadan, Samir Sahai said, “Rescue operation has been hampered due to bad weather. I was informed by the MEA (Ministry of External Affairs) that due to bad weather choppers could not operate in the hilly area to airlift people from remote areas. So far 307 people from Maharashtra have been rescued.”
 
After the request from the state government, a few amateur HAM radio operators in the city had rendered their skills in the time of distress to set up communication centers. A team of 15 HAM operators of Disaster Amateur Radio Emergency Service (DARES) joined Disaster Management cell of state and started an operation center.
 
Ankur Puranik, a businessman and an amateur HAM radio operator who is voluntarily working for state disaster said, “Since yesterday (Monday) 12 HAM operators surfaced in Nepal. We are exchanging messages like their demands and supply, stock of medicines particularly TT injections, antibiotics and messages to family members.”
 
Puranik added, “Phone lines are already damaged in Nepal. It is raining and there are heavy winds so mobiles do not have range. However, our operations are going on with some atmospheric disturbance.”
 
According to state government records, so far 307 tourist residents of Maharashtra have been rescued and landed in Delhi. Provision of accommodation is being made at Maharashtra Sadan and also transport provisions to their hometown are being made.
 
While talking to FPJ, State Disaster Management Cell Director Suhas Divase said, “We are in touch with National Disaster Management Chief Major General Anurag Gupta. We are also constantly monitoring stock of medicines, skilled manpower and other material.” He added, “The state had already sent a stock of antibiotic medicines, TT injections, bandage, hand gloves and other medicines.”

Another case of Amateur Radio coming into significance "When All Else Fails". If you're not familiar with formal message handling, at the very least, I would advise listening to one of your local VHF/UHF traffic nets. Become familiar with the procedures and formats used for passing third party traffic. The experience you gain via NTS would become very handy should you ever find yourself in a bona fide emergency communications event. Inquire with your local municipal governing body to find out if there's a CERT team set up in your town. If not, perhaps you can meet with the local Director of Emergency Management and discuss the possibility of starting one up.

It's better to be prepared and not needed than to be needed and not be prepared, and not knowing what to do.

QRP - When you care to send the very least!

Happy Morse Code Day!

Today is Morse Code Day, which of course, is celebrated on the birthday of Samuel FB Morse.


Does this make Samuel the original "Old Man"?  Sorry Mr. Maxim*, I think Mr. Morse has seniority on you for that title, as Mr. Morse would be celebrating his 224th birthday today, were he of the kin of Methuselah.

Now that QRPTTF is over, except for e-mailing in my log summary, I thought I'd post where my signal was being heard on Saturday, according to the Reverse Beacon Network.

 
Even though I didn't make any contacts on 15 Meters, it appears my signal was leaping over The Pond.  Not the loudest, but still making it.  Here's as much of the table was I was able to snip.
 


Bob W3BBO and I were discussing QRPTTF yesterday amongst ourselves, and it occurred to both of us that the western half of the nation seems to have reported larger QSO totals than the eastern half of the nation. This based on e-mails sent to QRP-L that we had read. Not sure what that means, but so far I haven't seen many e-mails from anyone east of the Mississippi with log summaries of around 40 QSOs or so. It will be interesting to see how it breaks down geographically once the results are in.

The EARCHI does get heard, and being on the top of a high hill (we call those mountains, here in NJ) sure makes a difference. And this makes for the other important lesson I've learned from events such as these.  As nice as it would be to come in 1st place in a contest such as QRPTTF, the real prize won is enjoying a day outdoors, playing radio in the fresh air and sunshine, being able to forget about everyday worries, cares and concerns, even if it's just for a couple hours.

QRP - When you care to send the very least!

* - For those of you who are new to the Ham radio game, Hiram Percy Maxim who founded the ARRL, often wrote editorials under the pseudonym "The Old Man". Since HPM lived from 1869 - 1936. I guess that makes Mr. Morse the rightful holder of "The Old Man" title.

QRPTTF – 2015

It seems for me at least, that these event hardly ever go as I envision them. In my mind, I get onsite early, with plenty of time to set up, which goes like a hot knife through butter. I have plenty of time to spend on the air, and just make scads of QSOs, then break down and come home, tired but triumphant.

As Mr. Lennon wrote, "Life is what happens when you're busy making other plans."

I had planned to get to Washington Rock State Park around Noon. The park, which is on the first ridge of the Watchung (Wach Unc in Lene Lanape) moutnains, meets the  QRPTTF theme requirement for being a place somehow related to Native Americans. What actually happened was that my daughter was invited to a sleepover/birthday party, and I had to have her at her friend's house at 2:00 PM. So much for the early start.



Set up did go like the knife through hot butter, after I made it to the park. The new Joplin ARC antenna launcher got my antenna hoist line up over a 40 foot high tree branch on the first shot.  The EARCHI was up, literally in minutes.

I got on the air at about 1830 UTC and I spent about 15 minutes calling CQ QRP on 15 Meters with no takers.  I had a feeling that 15 Meters was going to be good today. It wasn't, at least for me. So I meandered over to 20 Meters and was answered by Craig N8KMY at 1855 for my first QRPTTF QSO.

It didn't start out as a QRPTTF QSO. He called me because in his words, he couldn't believe that I was QRP.  He is located in northern MI and told me that I was one of the loudest signals on the band for him. He repeatedly asked me to confirm that I was only running 5 Watts.

He was as loud to me as I was to him, so that's where the fun began.  First he lowered his power from 40 Watts to 20 Watts, when I told him there was no difference in his signal, he continued to lower his power down to 10 Watts, and then, eventually 5 Watts.  He was astounded when I told him (quite honestly) that there was no difference between his signal at 40 Watts or 5 Watts.  A new QRP convert? I certainly hope so! Craig seemed enthusiastic enough.

Getting him down to 5 Watts qualified as a QRPTTF contact. We had a nice ragchew for about 25 minutes. A bit longer than I had intended, but it's never a bad thing to promote QRP, and bring a new soul into the fold, right? So it was worth it.

Besides, as it turned out, the bands weren't exactly rip-roaring with QRPTTF activity. I ended up making only 8 QSOs. Six on 20 Meters and two on 40 Meters.



I worked, in addition to N8KMY, NK9G, WQ8RP, K7RE, K4UPG (Kelly, my fellow QRP Polar Bear - Grrrrrrrr), WB3T, KS8M and AA5TB.

What made the day, was when my fellow SPARC members, Marv K2VHW (my official QRPTTF 2015 photographer) and Drew W2OU came for a visit.  They kept me company in between QSOs and also stayed with me until I packed up for the return trip home. Around 5:00 PM, it started getting chilly again and QRPTTF signals were becoming about as scarce as hen's teeth. So only though I put in only 2 & 1/2 hours behind the key, I decided to call it an event and head home.

The important thing was that I had fun and enjoyed my time playing radio today. It feels like I don't get to do this anywhere near enough.

They named a candy after me!

 
You may recall in my post about the Rookie Roundup that I had mentioned I used my EARCHI antenna, anchored to my 31' Jackite pole as a support. I had intended to shoot a support line over a convenient tree and was going to haul it up that way.
 
I started pressurizing my Joplin ARC pneumatic antenna launcher, but I couldn't build up any pressure. At first, I thought that perhaps my super cheapie WalMart bicycle pump had failed me. But listening carefully while stepping on the foot pump revealed a "whooshing" sound - so air was coming out.  Next, I thought that perhaps the Schrader valve on the launcher was busted. However, I manually manipulated the pin in the tip with a screwdriver tip and it came back after being depressed - so that was OK.
 
It was about then that Marv K2VHW said to me, "Larry, is that a big crack on the side?"
 
A HUGE crack on the side of the air pressure chamber, on the side opposite the valve - practically going down the entire side.
 
DUH!
 
That's when I remembered that last October, when I made my last outdoor QRP venture for the season to Washington Rock State Park, the launcher had slipped out of my hand as I was opening my Jeep door for the return trip home. It had hit the concrete parking lot surface pretty hard, but I didn't think twice about it at the time.  I didn't even give it a second look at the time. PVC is strong stuff after all, right?
 
I didn't notice the humongous Godzilla sized crack until Marv had pointed it out.
 
Call me Captain Oblivious.
 
I was going to try epoxying the crack. But air is like electrons - no such thing as a dumb electron - no such thing as a dumb air molecule. If either can find the shortest path, they will. I figured that once the pressure chamber was compromised, it was compromised for good.  Continually pumping air into it would probably only make the crack grow bigger, even after a patch job. So last Sunday night, I ordered another.  This is not something I would have normally done - my Ham Radio budget is EXTREMELY tight this year. But that launcher has become necessary equipment.  I'm not as talented a water bottle tosser as Jim W1PID, my arm is nothing that would scare Tom Seaver (even on my best day) and my sling shot skills are so-so to say the least. And don't even put me anywhere near archery equipment. Between the various outdoor QRP events and Field Day, that launcher has become a must have. So even though $50 is a big deal for me, the decision to order a replacement was a no-brainer.
 
I was thinking that there's no way it would arrive in time, but it showed up through the USPS on Wednesday. Talk about fast service - thanks Joplin ARC !  And how do you like that - the USPS delivered it to the right house! A lot of you are thinking that's no big deal, but there's a Clinton Place, a Clinton Terrace and a Clinton Avenue in South Plainfield. Sometimes my mail goes to other places, it can be a toss of the dice.
 
I built it Wednesday evening, after coming home from work and after typing up and sending out the local radio club's minutes for last month. The launcher is so easy to build that I could do it in my sleep - and in fact, I was so tired Wednesday night that it almost did get built while I was asleep.
 
I set it aside for a 24 hour cure, and pumped it up last night for a leak test. No bubbles in the water - yay! After pumping it up with 5 lbs of pressure, I did another check at 10 lbs of air pressure. Still no bubbles - double yay! Then a final test at 20 lbs of air pressure, as I rarely have to go above that to successfully launch an antenna. Good again - triple yay!
 
So I have a launcher for tomorrow - QRPTTF, and for the rest of forever. I am really going to be sure I never play dropsy with it again.  The spud gun has become too valuable a tool for me to be without.

A lot better today!

I saw another e-mail in my inbox this morning from Marv K2VHW with the subject "Another flare". I groaned loudly, inwardly, because no one near me would have understood.  Then, just before heading out to the Jeep at lunch time, I checked http://www.bandconditions.com/index.htm

That had me shaking my head even more.

I'm glad I didn't give in to the temptation to chuck it all for today, because I had the best QRP lunch time that I've had in a while - numbers and predictions be damned!

I started out on 17 Meters which seemed to be in great condition. Low noise level and some loud signals. I worked EA6NB, Jaime in the Balearic Islands.  From there I wandered around a bit and worked W4B a Special Event Station for Earth Day in Florida.

After that, I switched bands and called CQ near the 20 Meter QRP Watering Hole and was answered by Dick K5TF in Atlanta, GA.  Dick had a gorgeous signal. He was pushing 5 Watts out of his K2 to a Hexbeam (secretly, I am lusting for one of these babies.  Bob W3BBO and I always dream about getting one for our stations and my good friend and fellow DXer/QRPer Steve WX2S is in the process of installing one). Not only was Dick's signal excellent, but his fist was a dream to copy. The words were appearing in my brain as if I were reading a teleprompter. It was a very enjoyable, but short chat.


From there, I decided to spend the last bit of time that I could squeeze out of lunch break by calling CQ at the 15 Meter QRP Watering Hole on 21.060 MHz.  I was greeted there by Alberto WP4L for another 2X QRP chat. Alberto was pushing 5 Watts out of his Yeasu FT-450 and sounded like he was just down the street. And I might add, another excellent fist that was bliss to copy.

If the flare that Marv e-mailed me about helped provide the kind of band conditions that I experienced today, then I hope we get them all the time! Loud signals, quiet background noise - what more could you want or ask for?  The only bad thing was having to stop so that I could come back inside in order to finish the work day out.
