My First QRP Remote
Scott (VA3SLJ)

View comments about this article!
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.

Very cool, Scott! Just another example of low power can mean high fun.
As an aside, carry a box of Bounce (the anti-static sheets used in the clothes dryer to prevent "static cling") with you on your summer outings--if you rub the sheets on your skin and/or pin them to your clothes, it'll keep the mosquitoes away.
Ciao,
Rich

During the warmer months, I spend quite a few weekends camping at a local wildlife park where I have permission to stargaze. I usually take my MFJ 9020 (which I bought used at a hamfest for $30) with me to give me something to do during the day. Being remote and having no nearby power lines it's a very RF quiet location.
I constructed a simple inverted-V dipole using a 16-foot painter's pole, speaker wire, 20 feet of RG-8, insulators and two 6-foot wood broom handles. The antenna sets up in about 3 minutes. I run the 9020 off a 12-volt battery pack. I also bring a keyer and headphones.
Last month during the CQ WPX CW contest I was able to work Croatia, Slovenia, Serbia and Montenegro, Austria, Germany, Italy, Poland, Bosnia-Hercegovena, Asiatic Russia, Canada, and the Czech Republic all with less than 5 watts on CW. During off-contest periods I have worked almost all states and about 20 other countries including Mauritius (3B8CF, Jacky) with this setup.
I keep hearing the phrase "Life's too short for QRP" and "QRO's the way to go" but when it comes to having fun, QRP is an absolute blast.
The only downside to the location is that the park is about 60% wetland and swamp and has some very nasty mosquito problems, lots of ticks and big biting flies. I'll have to try the Bounce suggestion because I hate having to drench myself with repellant.
Tom,

I think eham is doing a great service to community by publishing quality articles like these. Ham radio is not just one facet but many different nooks and crannies. All are perfectly valid.
Great article to read. Maybe I will try QRP remote some time.

Portable operation can become one of the most pleasant corners of our hobby. I've had a fair bit of experience running QRP on scout campouts and Field Day. Here are a few tips:
1) Use efficient antennas. Dipoles up in the trees are much better than small, compromise antennas. Use low-loss balanced line and a tuner, and you can operate one antenna on several bands with great results.
2) Pick a good QTH. Hilltops are great, but don't set your self up for a lightning strike.
3) If there are lots of bugs, use a tent or shelter with insect netting.
4) In dry weather, don't worry about grounds. A balanced horizontal antenna fed with twinlead or ladder line does not need or want a ground. The only reason for a ground is to deal with static buildup. A metal tent-stake is sufficient to drain off the charge.
5) Portable operation is often easier and more pleasant in cool or cold weather. There are no bugs, there is less QRN, there is no lightning, there are few people in the campsites, and the nights are long. It's very comfortable in a tent inside a good sleeping bag. CW rules. Some radios are better than others for sleeping-bag operating!
6) Practice makes perfect. There's actually more effort required to operate portable than from a permanent setup. You have to work out your own routines. The more you try this, the easier it gets.
7) If you're doing more than casual operating, make a checklist for what you need to bring.
8) Be sure to bring instructions for any gear that requires programming, like keyers. Keyers seem to misbehave in the field - maybe it's static/ESD, which is a problem out here in the West. Be prepared.
9) Murphy's laws always apply to portable QRP operation. When Murphy strikes, try to accept your fate gracefully.
10) If you plan to use a fishing rod to put up your antenna line, be sure to bring a second reel and maybe even a second rod as well. The reel is the piece of equipment most likely to fail. Life's too short to untangle monofilament when the band's open.

I can relate!
I don't do portable, but I greatly enjoy mobile! I have, in times past, operated CW in motion, along with SSTV, and even ATV. Alas, as I have always said, age has done more for me than religion ever could have; I'm not that foolish any more.

More fun to wait till the winter and getting five feet of snow. Make yourself a igloo, stick your vertical pole in through the top of the igloo, heat up the coffee or hot chocolate. Makes qrp portable more fun.
In the summer time, dunk yourself into the murky waters where the mosquitoes breed, the mosquitoes will think you as a breed of the same and won't be troublesome.
Ask any Jungle Walla, how to survive remote qrp.
Qrp and in a remote qth is fun, five watts will do the trick for the day. Nice post.

Great story. When I first started I built the 2 tube reciever and 1 tube transmitter that was in the old ARRL Mobile manual. the whole thing fit inside the size of a shoe box today. I made lots of contacts on CW also.
For the antenna we used either a longwire and a clip lead to a sprinkler head in the park. (back then they used steel pipe) or
We used a box kite that we got surplus military or
if the wind was not blowing, we used a balloon.
We would get two or three from the vendor in the park that was selling them. Tie them all togeather and then let the longwire (light gauge) pay out till the weight of the wire equaled the lift of the baloons.
the kite was a dual challenge as not only did you have to keep it up but, try and make a contact on the radio at the same time.
the balloon idea was something I saw in the movies about WWII in germany spys. It worked great.
When done I would tie a QSL card to the bottom of the balloons and let it fly away. Always wondered where it went.
That was fun back then and lots of old WW2 Vets would gather around to share in the joy of the radio. I had lots of guest operators from the park back then. Lots of new potential hams too.. as it was not uncommon to have RC boats, Planes and people showing off hobby's back then.
The good old days. And no matter what your age is you still can enjoy the thrill of commucation other than a cell phone and computer. Oh but you needed to know CW back then too.

I've just added you to my list of folk who I owe a beer should you visit Budapest. That idea with the Bounce works just fine although I did get some very strange looks from the YL when I first tried it this morning.

Just tell her you want to smell sweet and breezy for the day :)
Actually I had never heard of that, and now I'm glad I know. I spent many nights last year fighting off bugs after using commercial bug repellent.

QRP/portable is one of my favorite aspects of our hobby. My favorite rig for this is a Tokyo Hy-Power HT-750, a 6m/15m/40m 3W SSB/CW handheld. I've been know to operate SSB QRP while hiking using a coil and telescopic whip made to match the HT-750 and trailing a counterpoise wire. That counterpoise dragged behind me may look funny to people but it makes all the difference in terms of getting out. It's worked very well for me, particularly on 15 and 6 when they're open. Those are very much QRP-friendly bands.
A dipole in the trees is the best antenna for picnic table portable provided you have nearby trees and provided you're any good at throwing or launching the antenna into the trees in the first place, which I'm not. I've had great success with an Alpha Delta Outpost ground coupled tripod and either an Outbacker (which I've now sold) or Hamsticks. I'm about to modify the tripod to use a UHF (SO-239) mount rather than a 3/8 threaded mount so I can use it with my Maldol HMC-6S mobile antenna. I think that combination will work very well indeed.
In addition to the HT-750 (my favorite ham toy) I've used the Yaesu FT-817 and various portables by Mizuho. Their P-7DX and P-21DX CW portables are particularly good.
It's all great fun and I don't know how many times people have told me that I had a great signal and just couldn't believe it when I told them what rig I was using, how much (or really little) power I was running, and what I had for an antenna.
Nice article.

Caity I want to mention sometimes those neat lil' HF HTs are hard to find, but the Elecraft KX1 was made for this kind of use also, to hear its designer speak, he spends a fair amont of time trailing a wire!
QRP portable rules. There's a group of us who get together on Thursdays and operate HF portable, generally QRP, in the park in Sunnyvale, at lunch time. There are some terriffic tall trees at one end of the park, and shorter ones scattered around. It's a great site. It's the park where they do lawn bowling.

Scott - Your article was great fun, and sure set me to thinking. I am reading (and replying to your article on my laptop, sitting at the picnic table in a campground near Old Hickory Lake in Middle Tennessee. In the background I am listening to the 7020 gang on an FT-817, and occasionally checking in QRP. Later, I will make a few more QSOs with the little rig and test out the portable antennas before Field Day next weekend. When I began hamming 40 years ago, none of this could have been in my wildest imagination. My, how things have changed. -73- and Have Fun! de W4SK

Actually the HF HTs are not hard to find if you know where to look. Three Mizuho HTs were offered on the Mizuho reflector in the past three weeks, one for 40m, one for 20m, and one for 6m. The KX-1 is a neat CW-only rig. The Mizuho Pico transceivers, Tohyo Hy-Power HT-750, and for that matter the Yaesu FT-817, are all SSB/CW rigs. I guess I'm just not coordinated enough to send CW and hike at the same time. CW is fine for picnic table portable, not for on the move, at least for me.
Also, when looking for more unusual rigs you have to be willing to look at eBay. Those who are allergic to that auction site are cutting themselves off from the single largest source of used gear there is.
Interestingly I only mentioned one HT (the Tokyo Hy-Power HT-750) in my comment. The Mizuho rigs I mentioned (P-7DX and P-21DX) are more conventional portable rigs.

I do the same thing, only with an old HW-7. It was cheap on eBay and didn't work, but was an easy fix. I made a couple of dipoles using 20-gua speaker wire plus 50-feet of RG-58. I use a 7-AH gell-cell, which powers that little HW-7 longer than I want to be out there operating.
2-watts on 40, 1-watt on 20 and 15, but that's enough for CW contacts when the bands are decent. All that's left is a set of ropes, a straight-key and set of headphones and i'm ready to go.
This is QRP Remote on a shoestring budget.

I like poratble QRPing. I had a 817 but ended up trading it for a better base station. When I had it I used Z-11 ATU with a balum and lots of wire. It did a very good job working all over the world, but ther wer times I wish I had a little more power.
Since then I have used a MFJ-9420 with the Z-11 with great results. This combo is light weight and easy to set up and run.
My latest investment is a Kenwood TS-50s with the power reduction modification that can be found on the internet. Adjusting three small pots dropped my power to 50/25/5 watts. The recieve current is a little high, between 700 to 800 ma, but I do have two 7 amp hr battery packs and rarely have to go to the second one. The TS-50 is small and fairly light weight and can be found on the on line swap meets at a very good price. I paid $325 for mine.
The antenna has been changed to a modified camera tri-pod with a ATAS-100 and homemade SWR/controller. I carry a roll of copper antenna wire that I layout as a counterpoise. It take me about 5 minutes to set the whole operation up with a SWR of less then 1:2 on all portions of all band. Communication is fast and very effective. And yes I figure I lost only a little over an hour operating time over the 817 with this set up believe it or not.
ATAS-100 can be bought at a song on line and at swap meets. I have two. One mobile with my TS-130SE and the other in my backpack. The last one I bought only cost me $75 and the homemade controller only cost about $15, which included a hackup RS SWR meter. The tri-pod I paid $5 for at a second hand store. The three things I like about this set up is that it is fast to setup, tuning on any portion of any band is easy and it really does get out and pulls in the dx.
I am now ready for fun under a tree in the forest or for any emergency that might come up. Hope to hear you on the bands someday...

For those contemplating their first QRP in the woods...yes worry about bugs. I haven't heard of the fabric softener repellant before this but I'll have to try it. Other things you want to think about are light and water. I have had so many horrible light sources while camping that I have designed a truely decent flashlight...anyone wanna fund me to produce it? ;)
One thing that most people don't bring enough of is water. When I was a kid I used to drink out of mountain streams but now it is not recommended.

One more item to your list, Robert: toilet facilities and *ahem* paper. There are portable/private toilets you can purchase from well-stocked camping supplies or sporting goods stores that you can take on (wait for it) the go. They're far better than most potty stations or *gag* Honey Buckets that are...well...vile. (That name leaves such a bad taste in my brain. Yeccccch!)
One more thing--and I'm not sure if I'm being sexist here or whether I speak Truth--women do _not_ like to do their business in the open or behind a nearby bush or tree. Trust me, guys--it's the voice of experience talking. :S
