Do they have to be LOUD to work them????

Learning a QRP lesson

I took advantage of another portable mobile QRP day again on Saturday. Once again using my Elecraft KX3, mono band HF whip antennas and QRP power. I decided right off the get go to use 20m whip antenna and I found there was a few CW contests going on. This is great as it gives me an opportunity to make some contacts......so I thought. I chose this day to cruise up and down the band for stations calling CQ and not CQ contest. I have been doing some reading in my spare time about QRP operation and making contacts. One of the tips I read I was actually able to put into practice and make a DX contact only using 5 watts with a mobile whip antenna. I was starting my run up the 20m band and at 14.007 I heard a very faint station calling CQ. I narrowed down my KX3's filter to around 200 Hz and he was still in and out, I was not able to pick out his full call as yet. When he started to call CQ again I turned the audio peak filter (APF) and started to fine tune his signal. Then low and behold I was able to get his call RA3XM, he was DX but what were my chances of making the contact???

1. He was in and out right at the noise floor.
2. He was not at the QRP watering hole so he was running most likely some kind of QRO power.
3. What chance did my QRP 5 watt signal have if I could barely hear QRO signal?

When RA3XM stopped calling CQ I threw my call out there and can you believe he came back to me on my first call!! I was shocked that I made the distance, it was not a long QSO but I did get a 559 signal report and I passed along to him a signal report, my name and that I was running QRP. It became crystal clear to me of something I read on more than one occasion from seasoned QRP op's....you may come across signals that are in and out of the mud, don't short change yourself ( I have done so on many occasions) thinking "they are QRO and in the mud they are never going to hear my peanut signal. Instead throw your call out there and you may be surprised......and when RA3XM came back to me from the noise I was surprised and pleased to make the contact. Spinning the dial once again I hear AN400R booming in (Spanish special event station) I gave him a call and and made that contact as well. On this outing it was not as simple as calling and making a contact there was F6EJN, DK7OB, AN400C, IT9RZU, MI0GH and AN400C all who I called and was not heard. A valuable lesson was learned on this outing.....even if the station calling CQ is in the mud give them a call and you (I was) may be surprised they come back to you.

Hunting for that one contact

In Canada it's the Thanksgiving long weekend and I thought I would add Friday as a vacation day to make it an extra long weekend. The weather has been great all week very summer like and far from fall like. I decided to take advantage of this fine weather and get outdoors with ham radio! This time it was going to be our local park with my car, so instead of the Endfed antenna My plan was to warm up the mono band HF whips. Apon arrival in the park I check with the website "band conditions" and it was showing all green on 30m. I thought "what the heck" I setup and the band was dead! I checked with band conditions again and low and behold the band was now deep on the red. It was off to the standby band.......20m. Going up and down the band I did find it quite but with the hurricane riding up the Eastern U.S. , it's Friday and lots are working and then the band conditions not idea the slow band made sence. I came across a station calling CQ at 14.041 followed by "up". Hmmm I thought....dxpedition or rare call. I engaged the dual watch on the KX3 and I listened for a bit and found there was no pile up in fact there was no one calling him! The call was AN400M that to me seemed like a special event station but at this point I was not sure from where? I set my KX3 for the common split of 2K and threw my call at 5 watts out there. He came right back to me with the standard 599 to which I replied the same adding TU and 73. From there I was just spinning the VFO around 20m and really did not find much. I did come across 2 other stations signing AN400G and AN400I and that convinced me I contacted a special event station. I tried calling these other station but was not able to make the contact. It was then time to pack it up as there was a Blue Jays game to watch at 1pm today. While at the local watering hole waiting for the Blue Jays game to start I went on QRZ.COM to find out it was a special event station out of Spain. They were offering a silver, gold and platinum awards but I was not able to get on their website it was not loading so I was not able to get anymore info.

NPOTA success – WR03

October 2nd, 2016 |

The day dawned gray. misty and chilly, but it wasn't downpouring. So I collected this bag of bones out of bed. I showered, shaved, got dressed and packed the Jeep with everything necessary for a ride to NPOTA land.

As stated a few days ago, the destination was WR03, the Delaware National Scenic River, via Washington's Crossing State Park, in Titusville, NJ. Thanks to the fact that there was hardly any traffic on an early Sunday morning, I arrived in about 45 minutes.

Everything was wet from the light rains and heavy mist that fell throughout the night. I made the decision to forgo using a soggy, leaf covered picnic table and used my camping table and folding chair from the parking lot, instead. This was not the main parking lot, but a smaller one, farther in the park. It was literally a stone's toss from the river.

You can see the 25' piece of coax going up to the PAR in the tree.

The set up was the usual, the KX3 at 5 Watts to a PAR END FEDZ 40/20/10 in a tree. I got really good height this time. The PAR was easily 50 -60 feet up in the air this time. And that was evident with the results - 43 QSOs in under 90 minutes. 20 Meters was LONG! I worked Belgium, Croatia, Hungary, Slovenia, Mexico, California, Montana and appropriately enough, Washington State. 40 Meters got me up and down the east coast and as far west as Minnesota.

I called it quits after about 90 minutes as the QSOs were drying up and I was starting to get a bit chilled. Oh, and there were skeeters! But NOT the kind that I like. I was swatting at them the whole time I was there. Who would have thought that mosquitoes would be out and about on a damp, and chilly day in the high 50s? After I packed up, but before leaving, I walked around to snap a few more photos.

This is a re-creation of one of the "boats" that were in use during Colonial times to ferry people and supplies across the river. It's really not much more than a glorified raft. So the painting IS right. Washington stood ...... and do did everyone else!

The house owned by the "ferry operator".

Later, when I had time to think about all of this, it was truly amazing. 2,400 men, some horses and artillery began silently crossing the river as soon as it got to be dark (There were British spies all over). Once they all reached the New Jersey side,they all marched the 20 or so miles to Trenton throughout snowy fields and made it there by daybreak. The effort just to get to Trenton must have been exhausting given the distance, the cold and the snow. Then they surprised the Hessians and won the battle without one Continental soldier being lost. Astounding!

All in all, it was another good NPOTA day. I thank all the chasers who worked me and I look forward to another adventure in a few more weeks - this time, maybe the NJ Pine Barrens.

Weekend plans go semi awry.

September 18th, 2016 |

Author: Larry W2LJ

I had planned on two Amateur Radio activities this weekend. I almost ended up going 0 for 2, but ended up batting .500 instead.

My first planned activity was to participate in the NJ QSO Party on Saturday. The work party that I attended at the Middlesex County Office of Emergency Management went longer than I anticipated. I'm glad we got the work done that we did, though, as it was important that it got done before the Simulated Emergency test in October. When I got home, there was still plenty of time to participate in the contest - no doubt. Other chores had to be taken care of first, though; and I made sure I got those done. End result? One very tired W2LJ and no NJQP on Saturday.

After dinner, I sat down with the tablet and saw on the ARRL NPOTA Facebook page that Peter K0BAK was doing a sweep of NJ activations this weekend, including AA17, the New Jersey Coastal Heritage Trail. My heart sank a bit because he's such a superb operator and activator - does AA17 really need to be activated twice the same day? And if you had the chance to work either me or Peter .... heck, even I'd rather work Peter than me !!!

When I went to bed last night, I was really iffy about making the effort. The weather was supposed to be suspect but I decided to sleep on it, thinking perhaps that maybe it might be better to wait for another weekend.

Sunday morning dawned muggy and overcast. Not exactly the greatest of weather conditions. But then the thought occurred to me that K0BAK normally does most of his operating on SSB, and mine was to be CW; so I decided to throw caution to the wind and decided to go to Cheesequake State Park, anyway.

I left the house a little after 9:00 AM and got to the park just around 9:30 AM. I found the Spring Hill Picnic Grounds to be deserted, save for a few parked cars. The occupants of those cars were all going off on hikes as the lot also served as the starting point for one of the park's many trailheads. With the picnic tables all to myself, I set up the PAR ENDFEDZ 40/20/10. The line went up over a 60 foot tree with ease thanks to my trusty Joplin MO ARC Antenna Launcher. I literally had the antenna up within minutes. I've had enough practice with the launcher to now get a good shot on the first try, at least 90% of the time.

The setup was the usual, KX3 to antenna, the Power Werk deep cycle battery, the Palm Micro paddles and a set of ear buds. The ear buds turned to be a life saver, as the picnic area turned out to be pretty gosh darn close to the Garden State Parkway, and there was lots of highway noise. In some cases, there were also some ignition noise moments. I thought I was far enough away where that wouldn't be a concern; but there must be a few vehicles out there that are close to being spark gap transmitters!

I got on the air at 1400 UTC, calling "CQ NPOTA" on 40 Meters at 7.034 MHz, and had my first QSO with W3JRR at 1415 UTC. I stayed on 40 Meters for about 45 minutes before taking a break to stretch my legs and to use the rest facilities. Thank the Lord they were open! I came back to the ear buds, and I could have sworn that I heard "BBO". I thought that was my good friend W3BBO looking for me; as I spotted myself on the Cluster. I called him a few times and heard no come back; so I decided to move on up to 20 Meters.

20 Meters turned out to be the better band. My farthest DX QSOs happened there with S58AL in Slovenia and ON4RO in Belgium. I also ended up working Arizona and Washington state on 20 Meters. So even though I made it to Europe, this is where the Reverse Beacon Network picked me up:

Just before 1600 UTC, I was visited by a Park Ranger who came to put up a sign showing that the picnic grounds had been reserved by a Baptist Church group for a BBQ. It was booked for 1:00 PM local or 1700 UTC. I decided to pack it in, anyway. My original plan was to put in about two hours, so that I wouldn't be away from the family for the entire day; and I put in my two hours, so I was happy.

The highlights of the day were working Kay Craigie N3KN, Dave Benson K1SWL of Small Wonder Labs and Rockmite fame, as well as Paul Signorelli W0RW, of QRP and Paraset Pedestrian Mobile fame. It's always cool when you go on an outing like this and hear the call signs of people you regard as friends. Not to say that ALL of you aren't friends ........ but you know what I mean!

37 QSOs later, my activation of AA17 was in the books for the day. I still hope to join up with Dave Hackett KD2FSI to activate the Pine Barrens and the Delaware Water Gap and the Appalachian Trail before NPOTA comes to a close - so stay tuned!
