QRP Remote

An article by: Scott (VA3SLJ)

I’ve been interested in amateur radio since I was in grade school. I was about 12 when I passed the Novice code test in 1968 or 69, at World Radio Labs in Council Bluffs, Iowa. Flunked the Novice test, though, and gave it up. In 1975 I passed a 3rd class radiotelephone licence exam so I could be a college DJ. Those questions looked really familiar. I’ve always had a shortwave set though, and have always dreamed of being a Ham.

Fast forward 28 years. Three kids, 1 grandkid, and a whole lot of life behind me.

Now a Canadian resident/citizen, I became VA3SLJ in 2003, code test and HF privileges and all. I’ve always been easily amused, and will never cease to be amazed that with less power than a nightlight, one can communicate around the world (or more likely, a thousand miles or more).

At home I have a Kenwood 830s, but I love the idea of working with a battery, portable radio and portable antenna.

So I’m ready to try remote/portable: October 2005, on vacation in Kansas, at the in-laws. I brought along an MFJ 9020, SWR meter, about 100′ of coax, portable 12v battery pack (the kind used for jump-starting cars), a hamstick, mirror mount, 2′ aluminium rod, and four radials cut for 20 meters. All I had to do was push the rod into the ground, fasten the mirror mount to it, connect the hamstick and the radials to the mirror mount (I had a predrilled a hole for this and connected all four radials to a common bolt), and run the coax. I did not need a tuner, because the hamstick can be tuned to 1:1 VSR across the bandspread of the 9020.

It all worked! I am a slow-coder, but was able to have a good QSO with a fellow in Long Island, New York, from rural Washington County, Kansas. Five watts—wow!

This did not count in my book as a QRP remote, however, because I was indoors, and just a little too comfy. Also, I didn’t really have time the rest of the week to make contacts. It didn’t help having nephews around (“Whazzat?? Whad’they say? Can you pick up police with that?) I’m happy to try to answer questions, but remember: “slow coder.” I need my concentration time. Other family duties croweded out radio time. From a non-ham point of view, being hunched over a radio listening to “static and beeps” does seem a little anti-social.

So I wait for the next chance. At home, I do little QRP, and just try to make contacts on my Kenwood. In 2003 my first QSO’s were all CW, because I didn’t have a mike. The solid contacts of the Kenwood, with filters, make for good code practise.

Next chance—back in Council Bluffs, at my father’s place. It is a balmy day in late February, and I’m on his back deck. I’m using the same radio, but brought the “No Counterpoise” antenna made of heavy twinlead. It requires a tuner, so I packed one and for power used a filtered wall wart. Because I was there to visit my father and not for a DXpedition, I didn’t have lots of time, but did make a great QRP contact in North Carolina! The thrill is still there. That antenna, by the way, is fantastic. It’s sold on Ebay most of the time.

This was still not a remote in my thinking. It was still indoors, and I was using AC! I’m really beginning to enjoy the idea of doing a remote QRP operation, but am having a tough time pulling it off. I’m beginning to notice a pattern: the best 20 meter openings occur at really bad times when you are supposed to be visiting people when on holidays. I need a time and place where I can have privacy to operate guilt-free.

June 1st, 2006, Stratford, Ontario. While my wife and daughter attend the play “Oliver,” I set up to operate in the park near the theatre. Stratford, Ontario, is famous for its Shakespeare festival, and is a beautiful city about 150 KM from Toronto. The park is full of old trees, with low branches just asking for an antenna deployment. I had a great view of the Thames, and the sky was almost cloudless.

So, after unloading my trusty 9020 and a Heathkit HW-8, I look for a good place for my hamstick antenna. I mentioned before that the Hamstick antenna does not need a tuner; true, but it does require coax to the radio—coax I left coiled up at the shack. So out comes my “no counterpoise” antenna, and I set it up at about 10′ off the ground. QSO with N2WN in Florida! Now I’m happy, and have more time to make contacts. But now I am beset by the worst QRM ever, and I’m not talking about the guy on SSB on the QRP calling frequency counting out numbers (if you were doing this at 00:15 Z on 2 June 2006, you should know better). No, the QRM I’m talking about is when the “M” stands for mosquito! Besides my coax, forgetting the bug spray was my worst mistake. I was only a hundred meters or so from the river, but thought that since it was running water I’d be safe. I had to beat a hasty retreat. Too bad, because I had the time, a good band, and coffee!

But I was “remote” with portable power, lawn chair, coffee, and my 7 month old Labradoodle keeping the van safe. I just can’t handle all that QRM: -.-. slaa slaa slap slaa just doesn’t do it.

What’s been going on with AD7MI?

It’s been a busy summer so far.

– Memorial Day: I really enjoyed the special event station operation – W4M. I operated from Fort Monroe on Saturday and Sunday from a WWII coastal artillery battery overlooking the Chesapeake, wonderful weather and some great contacts. I setup a G5RV for the antenna and used a portable generator for power.

– The Smithsonian, NN3SI: During my trip to Washington DC, I had the opportunity to be a guest operator at the Smithsonian’s own amateur radio station, located at the Museum of American History.

– Lighthouse Activations: Enjoyed a relaxing few days down in the Outer Banks, NC and was able to activate the Bodie Island Lighthouse (USA-067) and the Currituck Beach Lighthouse (USA-212). Link here to the Outer Banks Repeater Association: http://obra.aginet.com/

Scott – It was a pleasure to meet you – if only on the air.
Re: the the UHF side of the mobile radio. Might consider selecting medium or low power when running mobile – especially when the repeater of choice is not far away.

I am sending along a URL for a tape measure beam. Originally, I think the author meant to use it in DFing – Direction-finding – competitions – but despite the fact that it’s rather ugly and makes lots of noise when the wind blows the elements – it seems the ideal solution for accessing a repeater from a remote (vacation) location.
I bought an el cheapo grande 25 ft. tape measure a few years ago, and 8 bucks worth of the PVC tubing he recommends.
There are several of these antennae in my workshop. One thing I did was to cast a couple of concrete bases – using galvanized pails that I bought at ACE.
One 60-odd bag of Sak-Crete will let you make a couple of bases. Glue some scrap carpeting to the bottom and you’ve got built-on floor protection.

As presently described, the tape measure antenna is only good on 2 meters. The author mentions that it may well be possible to change the element dimensions and spacing to put it into the UHF portion of the spectrum. I may try one out on 70 cm, with a watt meter in the line, just for grins.
Keep in touch.
If you wish, I will add your address to the OBRA email list, which will keep you informed about major doings around here. You would not get a lot of mail from OBRA, believe me.

Next project: I’m working on a portable HF/VHF/UHF system. Intent is to build a complete setup (rig, power supply, tuner, SWR meter, NOMIC RigBlaster, etc.) into an easily transportable box.

The Devil Drove Up To Dayton

The devil drove up to Dayton, he was lookin’ for a hamfest deal.

He was in a bind, cause he was way behind, so he was ready to make a deal.

When he came across this young man sittin’ in the Salem Mall parking lot.

And the devil jumped up on a Skywarn van, he said, “Boy let me tell ya what!”

“I bet you didn’t know it, but I’m a ham operator too.”

“So if you care to take a dare, I’ll make a bet with you.”

“Now you send pretty good code ol’ boy, but give devil his due.”

“I’ll bet a straight key of gold against your soul, cause I think I’m better than you.”

The boy said, “My name’s Mikey, and it might be a sin, but I’ll take your bet, and you’re gonna regret, cause code’s all I ever send!”

Refrain:

Mikey plug in your key and send them dits and dahs. Cause hell’s broke loose in Dayton, and the devil deals the cards. Now if you win you’ll get that shiny straight key made of gold. But if you lose, the devil gets your soul.

The devil plugged in his key, and he said, “I’ll start this gig.” And sparks flew from his linear amp as he was tunin’ up his rig. And he started sendin’ dits and dahs, and they made an evil hiss. And then a band of demons joined in, and it sounded somethin’ like this.

(Insert CW QRM Noise)

When the devil finished, Mikey said, “Well you’re pretty ole’ son, but sit down on that linear amp, and let me show ya how it’s done.”

(In CW he sent)

Hey now devil, I got some skill. Devil’s lookin’ for a hamfest deal. Listen now devil, don’t ya whine! That gold straight, she’s a gonna be mine!

Well the devil bowed his head, because he knew that he’d been beat. And he laid that golden straight key on the ground at Michael’s feet. Michael said, “Devil just come on back if ya ever wanna try me again.” “I done told you once you son of a b-tch, I’m the best that’s ever been!”

Lightship New Bedford rolls over at its berth

This story is based on an article in the New Bedford Standard-Times of June 2, 2006.

Apersistent leak has caused the Lightship New Bedford to roll over on its side at its berth at the Commonwealth Electric Pier in New Bedford. The ship, owned by the city of New Bedford, could remain on its side for at least a week, according to John Simpson, executive director of the New Bedford Harbor Development Commission. The city is seeking estimates to lift the vessel out of the water for examination and repair, he added.

“We need to determine the cause (of the leak) and prevent it from happening,” Simpson told reporters.

According to the Coast Guard, the overturned lightship does not create any navigational or environmental hazards. “From what we know, there is no fuel onboard,” said Petty Officer Tiffany Carvalho of Marine Safety Detachment New Bedford.

The deactivated lightship has been leaking for several week, Simpson said, and had been pumped periodically. The city had intended to seek financial assistance from the Massachusetts Seaport Advisory Council for repairs. “It’s now a situation we have to deal with,” he said.

The 133-foot (40.5 m) lightship was added to the National Register of Historic Places in 1980. One of only 13 surviving U.S. lightships, it has been in poor condition for years and is listed on the Lighthouse Digest Doomsday List. Lighthouse preservationists were quick to express their concern. “Let’s hope efforts to right the vessel and stop the leak that caused this disaster are successful. With so few lightships left in the country, we can ill-afford to lose this treasure,” said Bob Trapani of the American Lighthouse Foundation.

W4M – Day One

Wow! Day one is over – a total of 78 contacts to include two new states for me… Nebraska and Delaware. Worked a number of other states as well to include Washington, Texas, Iowa, Illinois, Ohio, Alabama, Florida, Georgia, New York, New Jersey, Vermont, New Hampshire, Maine, North Carolina, Missouri, Kansas, Connecticut and Pennsylvania. Also a few into Canada.

Biggest lesson from today – operating a portable station away from a vehicle on generator power using a G5RV is a lot of setup work to do by yourself. I set my station up on the top of a WWII coastal artillery battery, taking advantage of the extra height and incredible view. However, this also entailed hiking up down a series of stairs with all the gear. Also learned some better techniques for using the G5RV. My intent was to use two painter’s poles nested one on the other with a 1/3 of the bottom sticking into the top one. I attached the center point of the G5RV and then tried to raise the pole to the vertical. The bottom pole’s top 1/3 ended up snapping due to the weight. What I should have done is run a line through the eyelet at the top of the top pole and then raised the center point once I had stabilized the pole into a vertical position. Also – I need to secure the guy-wires to the side of the pole, the guy-wires got needlessly tangled when I did finally get the pole into a vertical position.

The generator worked quite nicely – I had no issues with it at all. It started right up, operated quietly, and had hummed away nicely until I shut it down.

Overall, it was a good day and I learned quite a bit. Tomorrow’s operations should go a lot smoother.

International Lighthouse/Lightship Weekend-2006

This highly popular and ever growing amateur radio event is on again this year on 19-20 August. In 2005 we had 382 lighthouses in 48 countries who registered on our web site. This year’s event in particular will be dedicated to the memory of its founder and main organiser, Mike Dalrymple GM4SUC, who passed away in December 2005. The event normally starts at 0001 UTC on Saturday 19th August and ends at 2359 UTC Sunday 20th August. This year we will start at 0002 UTC reserving the first minute in silence as a moment of reflection on Mike’s life.

As you all know by now the event is a fun weekend designed to promote amateur radio and lighthouses. It is NOT a contest so take time to have a chat with the stations contacted and maybe get the public involved as well. On the Sunday the International Association of Lighthouse Keepers will hold their Lighthouse Day opening their lighthouses all around the world to the public. Last year some stations even had the media present taking film of the event.

Full guidelines, an online entry form and a list of entrants are all on our web site at together with contact details if you need further information. So, come along grab a lighthouse and join in the fun. It’s also a great opportunity to increase your DXCC contacts and other lighthouse awards.

Busy day…..

(1) Complete support pole for G5RV feed point….
– this is complete except for the guy-wire. I need to get guy-wire for the upper 1/3 and lower 1/3 of the mast. I think the mast is going to work out well. It is composed of two painter’s poles (Mr. Long Arm). Each has a maximum length of 23′. For the upper section, I cut away the handle on the bottom. This will allow me to nest the upper portion’s lower 1/3 into the bottom portion’s top 1/3 of the pole. I think the total height of the mast will be around 38′. Also drilled a hole in the very top of the upper section and put an eye-bolt through it. Attached to the eye-bolt is a d-ring. I will attach the top of the feed point for the G5RV to the d-ring. As long as I can get some guy-wire… I’ll be good to go.

(2) Prep supports for the G5RV ends….
– got two large buckets from Home Depot. I placed a 3″ piece of PVC pipe (length just over the lip of the bucket) vertically in the center of the bucket. Around the pipe I put in about 4″ of cement. Turned about pretty good. I’ll be able to slide in a 2 1/2″ PVC pipe (10′ long) into the bucket and use it to secure the ends of the G5RV.

(3) Get a pop-up shelter for the operations table….
– got it at Target. 10′ by 10′ with a mosquito net. It will probably due okay in light rain, but not much more.

… and that was it for the list.

I did set up the FT-817 outside with my new RigBlaster NOMIC. Worked pretty good, got an PSK31 contact on 20M from Iowa with 5 watts. Have not set up the Tokyo amp yet.

Preparation for W4M

Only 5 days left to prep for the W4M special invent station. The recon is complete – I’m moving off the moat down to the Irwin Battery. The upper battery puts me at almost the same height of the Old Point Comfort Lighthouse. And the view is fantastic.

What’s left to do:
(1) Complete support pole for G5RV feed point
(2) Prep supports for the G5RV ends
(3) Get a pop-up shelter for the operations table
(4) Fix dipole vertical
– re-solder connection to base
– strengthen pole support
(5) Update USAARS website
(6) Create special event operator script
(7) Prep log books
