Playing Around With Reverse Beacon Network

August 22nd, 2013 |

After parking at my usual lunch time portable operating position, and not hearing much on the bands, I decided to do something I had been wanting to do for awhile now.

I have been wanting to play around with the Reverse Beacon Network using my portable QRP antenna. When not hearing much on the bands, I wanted to see if there was just not many operators, or if the band was actually dead. The other thing is that many times when I call CQ I call at less than 15 wpm because that is where I am most comfortable. I have never seen many reports on RBN in the past when calling CQ so I wanted to see if speed made a difference.

So I started off with 20 WPM and called CQ for about 3 minutes on 20 meters. You can see the spots on the photo, but I was heard mainly to the East coast and West part of the country – and one Canadian station.

Then I went down to 14 WPM and called CQ again – as you can see on the photo. At 14 WPM, my signal was still decoded and I got spotted by 5 stations. Where at 20 WPM I was spotted by 6 stations. So not really much difference. I did change frequency so that it would show the new spots.

I didn’t call as long at 14 WPM because I heard someone answering!

KO4OP – Rick was answering my CQ and had a nice sounding signal. He was in King William, VA. He was 599 and he gave me a 559. We went on to have a nice 15 minute exchange – really nice QSO Rick! Thanks for giving me a call!

As you can see in the picture I then went to 17 meters and put out a CQ at 14 WPM and was spotted by 4 stations (3 on the east coast and one out west). I did hear someone call ..__.. (?) after one of my CQ calls but I never could reach him, and they never gave a call.

After this I did hear NE1SJ very, very weakly calling from a SOTA summit on 20 meters. I gave him a call and he heard me, but when he came back he got weaker and I just could not pick him out of the noise. Sorry we couldn’t make it today – I would have liked to pick up some more points!

It seems my SOTA chasing has stalled a bit. Lately 20 meters seems to be skipping right over me here in Kansas!

So the RBN site was fun to play around with. It just tells me that even when you don’t hear anything, it doesn’t mean that you aren’t getting out! Put out some CQ’s and have some fun!

IZ4RTE & UX1AA – Amazing Lunchtime Portable QRP

August 20th, 2013 |

Author: Burke NØHYD

Map from N0HYD to UX1AA

Wow! It was a fun lunch today working portable from the park. I heard a little activity on 15 meters, but then tuned down to 17 meters and started having fun!

I had TWO great DX contacts on 17 meters today…

IZ4RTE – He was first up. He was calling CQ and after several repeats of my call he finally got it. He gave me a 519 and I gave him a 599. Eddie was near Bologna, ITALY! I don’t know call prefixes well enough to recognize where people are from – so I was super excited when he said this. From his QRZ profile apparently he was running a Elecraft K3 – so this was a nice 2xElecraft QSO.

UX1AA – I heard Serge finish a QSO and start calling CQ. It took several attempts for him to get my call, but he finally did. He gave me a 559 and he was 579 here in Kansas. When I looked him up on QRZ I realized he was in the western part of Ukraine! This is roughly 5,600 miles from my location!

It was about time to head back to work, but I spun to 20 meters and heard nothing, so I put out a CQ on 14.060. N7BBH – Steve in is Arizona. We have worked each other before in early August. Today he was on his TenTec Eagle at 40 watts – sounded great!

Well, another fun lunch time working QRP portable with my vertical EF QRP antenna. Its always fun, but today was exceptional with two nice DX QSO’s and working Steve again!

2nd annual Skeeter hunt contest

August 12th, 2013 |

The operating chair

The Skeeter hunt is a great QRP contest that has really caught on with the QRPer's. It's only a 4 hour contest and offers extra points if you want to take on a challenge. Last year it was to brew up a home made key and use it in the contest. If you did this (supporting photo's needed) then you picked up huge bonus points! Well last year I was not able to come up with a homemade key so the bonus points were out the window for me. This year the challenge was to operate beside a body of water......no problem for me as there are 3 rivers within 5 minutes or less for me.

Storm clouds

I scooped up my bonus points (passed along the pic's to back it up) but I was not able to make the same amount of contacts that I did last year. There were some factors to this, conditions had changed from last year, I worked an all nighter on Saturday so I was operating on more that 24 hours without any sleep and thus I did not spend as much time in the test........well a 1/2 hour less. I used my Elecraft KX3 operating on the internal batteries. The antenna was a mono band 20m whip from my car. I was going to use the Alexloop so I could take advantage of more bands...but...the weather conditions were looking very stormy. I did not want to take a chance and have the Alexloop damaged from rain.
The weather turned out to be great it did not rain but the storm clouds over head kept it cool and the sun off me. I operated from Riverside park which is a great park about 5 minutes from my QTH. Funny thing I never had anyone come up to me wondering what I was doing! In the past this has happened and it gave me a chance to explain ham radio. Something new in the contest this year is operating SSB, I did not take advantage of this and stayed CW and just single band.

A look towards the river

Some of the highlights were contacting TF/LX1NO (who was in the WAE contest) for whom you get bonus points for! Also I brought along an extra external battery just in case the AA internal rechargeable batteries died on me. To my surprise they lasted for 3 hours with me constantly calling CQ BZZ.

Another shot of the river.

So I was able to make 18 contacts with a total score of 1396. Funny thing my last years score was 1392.....So technically I did better than last year by 4 points!!!

Do QRP’ers Have an Identitiy Crisis?

August 12th, 2013 |

Author: Mike AD5A

So I was browsing the QRP Blogs today and I read about the most recent QRP contest. It occurred to me that maybe QRPer's have self esteem issues. Two of the activities that seem to attract a lot of QRP'ers are, "The Flight of the Bumblebees" and "The Skeeter Hunt". So, as I contemplated the deeper meaning, both the bumblebee and the skeeter are annonying creatures that bite you and yes, even carry disease. People actually spray chemicals on themselves to keep bees and skeeters away. Now I ask you as a fellow QRP'er; is this really who we are? Skeeters and bees, should these be the mascots of QRPdom? We should rather associate ourselves with the sly, skilled animals of the forests that we are, those that through their guile and agility are able to strike quickly and capture their prey. Why can't we have, "The Flight of the Eagles" or "The King of the Jungle Hunt". These symbols, or mascots if you will, would invoke a much stronger sense of purpose and pride, we can hold our heads high and make cool T-Shirts, while demonstrating to the world that indeed QRP'ers are a force to be reckoned with. We could say, "come join us in our hunt for the Lions this weekend", instead of "hey, wanna go skeeter hunting?". Anyway, just some thoughts, skeeters and bees or Eagles and Lions.

Emory Peak Activation

August 4th, 2013 |

Author: Mike AD5A

Emory Peak (7,825 ft) is the highest point in Big Bend National Park in Texas. As previously posted I had activated Mount Locke in the Davis Mountain the day before. Mt. Locke was a relatively easy activation , but I would earn my points and more on Emory Peak.

For those not familiar with the Summits on the Air (SOTA) program there are bonus points added for activating a summit either during the winter in cold climates or during the summer in hot climates. West Texas is definitely a hot climate. Emory Peak is a 10 point summit (maximum), but activating in the summer months is worth 3 extra bonus points. On the drive from Mt. Locke to the Big Bend area temperatures hovered between 99 F to 101 F. The temperatures would moderate a little at the Chisos basin where we were staying, although not a lot. The Chisos Mountain Lodge is around 5500 feet in elevation, but the high temperatures during this time of year are in the low 90's.

The Chisos Mountain range within Big Bend National Park is a beautiful place. Emory peak may be the only peak that is climbable, but even then, you must climb the last 35 feet using some, not so easy, rock climbing techniques. I would not recommend it if you aren't experienced.

The trail to the summit of Emory Peak is a very nice trail. It is well marked and maintained. The only issue is that the round trip is 9.4 miles and there is 2,500 feet of elevation gain. Given that distance the elevation gain is not particularly difficult, if you are accustomed to mountain hikes, but it is a long way.

Emory Peak Trail

The Peak is in the background

We started relatively early, 7:30 am. I wanted to start sooner, but my XYL was nervous about the warning about hiking too early. The Big Bend National Park and the Chiso's Mountains in particular have Mountain Lion and Black Bear populations. Both are sighted quite often, but Mountain Lions in particular are active in the early morning. We had to check out of our hotel room at the Chisos Mountain Lodge by 1:00, so we needed to depart the summit by 10:30 by my calculation to get back in time. I figured 2.5 hours up, 30 minutes to operate and then 2 hours back down. If my calculations were correct, 7:30 was the latest we should start. My wife and I are in relatively good shape, so I felt 2 miles an hour was a doable pace considering we were gaining 2,500 feet.

VHF Antenna above are on the Summit

The hike up wasn't too bad. Most of it is in the shade as the sun comes up over the mountains. It is a nice hike through a mostly forested trail. The last mile up was exposed to the sun, but there were still patches of shaded forest and the temps were bearable. We reached the summit around 10:00 am, right on schedule.

From my research I know that there weren't any tall trees on the summit, so getting an End Fed Half Wave antenna high enough would be an issue. I also know that time would be short with a hike this long, in the heat, so I needed to be able to deploy quickly. I decided on the Buddi-stick vertical. I only planned to operate on 20m, given the short time, so the vertical made sense.

You can see the Buddi-stick if you look closely

So I quickly deployed the station knowing that I would only have a short time to operate. I propped he vertical against a tree limb and then extended the counter poise over another limb. I took out my SOTA notebook station, seen above, plugged in the LIPO battery to ATS-4 QRP radio, grabbed my Porta-Paddle and I was ready to go. I called my first CQ at 10:13 am CDT. My good friends from Santa Fe, NM, Doc, K7SO and John, K1JD were monitoring my advertised frequency of 14.061. Doc answered my QRL? :-) John quickly followed. What then happened was SOTA bliss. The vertical was working well and in the next 15 minutes I made 21 QSO's. I wished that I had more time, but we needed to get off the mountain, both to beat the heat and to avoid an additional day's charge on our hotel room. So I took the station down as quickly as it went up, packed it all up and Cris and I headed down the mountain. We didn't get away until 10:45, a little behind schedule.

The trip down was uneventful, just long and the last mile or so, the heat was getting just a little on the uncomfortable side. However we were fully prepared, we carry 100 oz Camel Back water bladders in our pack, so we stayed hydrated. We made it back to our room at 12:55 pm. The good people at the Chisos Mountain Lodge let us shower and clean up before check out without an additional charge. I personally think it was self serving on their part as they didn't want us eating in their restaurant smelling like we just came off the trail:-)

This was a challenging hike, but completing it left us feeling good that we can still do it. The radio portion of the adventure came off without a hitch, so it was a good day in the Chisos.

SOTA Activation, Locke Mountain, Davis Mountains, TX

August 1st, 2013 |

Author: Mike AD5A

This was fun activation today. Locke Mountain is the home of the McDonald Observatory and you can drive most of the way to the top. There is a short climb to the summit from the parking lot. Locke Mountain is in the Davis Mountains which this time of the year is like an oasis in West Texas. Everything is green and the mountains are beautiful. The only problem with this area is that so many of the peaks are on private property. I need to do a little more research to find ways to get on them. I tried to get permission to do Guide Peak, another 10 pointer close to Locke Mountain, but the owner said no, this time.

Today,because of a potentially crowded summit, it wasn't, I used an Alex Loop for the first time. Very pleased with the results, ~30 QSO's on 4 bands with my ATS-4. I actually did two stints on the summit. After lunch in Fort Davis I went back up to try to work a few more guys while my wife shopped in town. Fort Davis is a very nice town.

Tomorrow I will try Emory Peak in Big Bend National Park, W5T/CI-009. This is a 9 mile round trip. I will be on the trail early, but if it gets too hot, I will call it a day. Check out www.sotawatch.org for spots. I will try to summit between 1400-1500z on 2 Aug.

K4UPG FOBB 2013 Antenna on da Ground!

July 31st, 2013 |

Author: Kelly K4UPG

Grrrrrrrr! and then more Grrrrrrrr’s! FOBB 2013 was a gud one! Grrrrrr!

Anticipated rain and thunderstorms and was not disappointed. Accordingly, I took up my backpack and walked about 1/2 mile to set up under a small pavilion in our housing development’s lakeside park. So far, so good. Originally I planned to have an EFHW for 40m and another one for 20m. Upon unpacking, realized my 40m wire was in my other pack at home. SHUCKS. I had already put a shot over a 40′ high branch and pulled up a paracord to hook to the wire which was not available. Oh well… it happens even to the best of us, eh?

Grrrrr! So I tried to set up the 20m EFHW and after another great shot with my 1 1/2 oz sinker and pulling up a line realized the tree wasn’t going to give me a good shot as it was too close and not very high. Grrrrrrr=ed a bit more!

K4UPG FOBB 2013 BB#23

Rethinking mode kicked in and was glad I got out early so all the wasted time did not mess me up. Pulled out my handy 20 ft Jackite and a 17 ft crappie pole and decided to give up on a typical K4UPG “hang ‘em high” antenna and do a very Lazy L. I tried to orient it for a bit of slope towards 330 degrees which shoots from FL to Iowa and provides decent coverage of most of the US. Turned out that low antenna worked great but I think the band was pretty doggone decent for a change too.

So about 15 min before FOBB start time fired off a CQ and made a contact and shot the breeze for a bit to warm up. Nice QRP to QRP contact but not counted for contest. Just for grins. I did notice a few “early out of the blocks ops” were calling CQ BB about 10 min before the clock struck go! Grrrrrrrrr! Sync those watches gentlemen!

Contest Started:

First station heard was Cam out in California N6GA but no joy when I responded to his CQ as there was a mini-pileup on him. Grrrrr… Heard a few more 6′s during the day but no peep from Rem Bear or any others I recognized. I did end up with eight PB’s for the day though and a great TU and Grrrrr to my fellow PB’s: AF40 Chuck- PB 153 TN my last contact of the day (more later); Snowbird FL Bear Don K3RLL PB 187 in PA with his new KX3; Jeff K9JP PB 175 in MI was the loudest signal of the day and blew my ears out till I got the RF and AF turned down Grrrrr! didn’t recognize you as a PB… sri bout dat; N1EU Barry in NY PB 336 got a Grrrrr!; N3AAZ John in MD PB 276 sri 2 ya… missed a Grrrrr!; W1PNS Pete in MA PB 348 got a Grrrrrr!; W5ESE Scotty beam me up Bear PB 287 missed a Grrrr too; WA8REI a perennial PB contact for me gave me a PB 21 style Grrrrrrr! I was closing a contact and Blackjack Bear called me on the guy’s freq so kept it REAL short and sweet as I felt like if we tried to QSY there was too much traffic and we’d not make the connex. Sri Ken Bear was a messy QSO cuz of that. Missed hearing Larry W2LJ this time and listened fur some of you udder PB’s but no connex. Grrrrrr!

All in all worked 25 QSO’s in 17 states and all of them were BB’s! Lightning came up as I was finishing my QSO with AF4O and it was TOO CLOSE. Almost blew me out of my seat but I held onto the key and finished up. Sitting there holding the wire and I started singing, “Antenna on the ground, antenna on the ground, when da lightning is around get your antenna on da ground” to the tune of the famous “Pants on the Ground” song by “General” Larry Platt.

Thus ended a nice outing after 2 hrs and 45 minutes but I truly enjoyed this one. Great number of participants and bet I could have almost doubled the numbers if the lightning did not end the day. Was hearing a lot of new calls just prior to shutting down. At least I got to give the serious contesters some points this year. Maybe next year will be my turn fur sum extra Q’s ? Grrrrrrr!
