Just a reminder

that next Monday, June 20th, is the first day of Summer. And you know what that means ..... Skeeter numbers will start to be issued that day!

Beginning this year, the Hunt has been moved to the third Sunday in August in order to even out spacing a bit between FOBB, the Skeeter Hunt and the NoGA Peanut Power Classic.  Also, there are some rule changes for 2016 in order to more fully incorporate NPOTA into the Skeeter Hunt. Make sure to check them out at www.qsl.net/w2lj.

A visit with a QRP contest station

160m Spring Stew Perry Contest - QRP style

I had the opportunity to visit with Paul Stroud AA4XX as he worked the early hours in the 160m Spring Stew Perry Contest.  Paul is an avid CW operator dedicated to QRP and QRPp operations.   When he works contests he often participates using the Knightlites club call WQ4RP (Note the QRP in the call).

160m Top Band

160m (top band) is challenging due to the physical logistics of a suitable antenna.  I had the opportunity to assist with a portion of raising the 160m vertical loop antenna at the "Excalibur antenna site" and installing the 24 elevated radials that help make this antenna so effective.  There's a lot of wire in the ground system.  The antenna site is located in the woods, off grid, and away from electrically noisy homes.  

Power to the remote shack is supplied by a quiet Honda 1kW generator operating a couple dozen feet from the shack.  Due to the lower power requirements of QRP Paul can run the generator on eco-mode allowing its small fuel tank to provide 8 hours of operation between fill-ups.

Paul uses a Ten Tec Argonaut VI, running 5 watts output into the Excalibur 160m vertical loop.  He uses N1MM+ logger software and a WinKeyer interfaced to the software.  He also employs a SDR (software defined radio) feeding CWSkimmer signals across the band.  An antenna splitter simultaneously feeds the SDR and the Argonaut. The SDR receiver is switched out during transmit by a DX Engineering RTR-1A Receive switch.  His CW key is a N3ZN ZN-QRP model.

The N1MM+ logging software keeps track of which stations have already been worked and the CWSkimmer interface displays calling stations on the band being heard by his antenna.


The remote QRP station setup for contesting

In the Stew Perry contest the only information exchanged was grid squares.  I'm still relatively new to CW and watching Paul casually copy grid squares sent at 30wpm was impressive.  I would have had to ask the caller to re-send their grid squares 5 times but Paul makes it look easy.


Instructions for the newbie

Paul explained to me the in's and out's of operating in a contest.  Speed and timing the openings were important, as was persistence. The integration of the software and receiving tools optimized his operating but experience and skill seems to be the biggest factors to success.  I could have sat down there using the same tools but I would have been dumfounded with the logging controls and the speed the other stations were sending information.  However, not all stations were sending at mach speed.  When Paul worked a station sending at a slower or faster speed he would use the interface to Winkeyer to speed up or slow down the sending simply using the Page-up / Page-down keys.  He would change frequency to a new station in the skimmer display by clicking on it.

Due to the limited amount of information exchanged during the contest most of the sending is accomplished via macros programmed into the contesting software.  Paul rarely had to touch the CW key during the time I was there and his primary physical interaction with the radio seemed to be changing bandwidth or bandpass settings (he tends to keep bandwidth at 500Hz).

Why QRP?

This contest was not a QRP-only contest although there were multipliers for working QRP.  There were plenty of big gun stations operating and the Reverse Beacon spots showed some of them with 56dB SNR reports pounding the ionosphere with their big amps.  

The strongest signal spot  last night for WQ4RP was 35db with the average at around 18dB.  Paul has worked QRO in the past but the challenge of QRP operation is now in his blood.  During a previous 160m CW contest this winter he and Dick Hayter N4HAY worked 3 stations in Hawaii with Excalibur which thrilled them given the current propagation on 160m.  QRP adds a bit more challenge and those multi-thousand mile per watt contacts on the top band make it all the more special

Why contest?

As a new CW operator I'm still getting my feet wet and enjoying the process of improving my CW copy skills doing more ragchews than adding stations to the log or chasing DX.  I casually contest with the SKCC weekend sprints and it can be fun to see how many stations I work but I'm not ready for real contesting.

During the time I observed, I could sense Paul's excitement seeing the propagation progress across the band and when a distant station in Russia was heard he looked forward to the challenge to getting that one in the log using QRP.  He let the stations running big amps get their fill before jumping in.  Ultimately he wasn't able to work that station but he later worked a GW3 station in Wales which was a first for him on 160m.  The rewards of contesting seem to be in the accomplishment of something difficult and achieving something new.  I can understand that.

What's next?

With summer coming on 160m will turn noisy from atmospheric static and the opportunities for top band contacts fewer.  Attention will turn to other bands and challenges for a while.  Maybe Paul will decide it's time to get that 40m Moxon back up on the tower as the sunspot cycle decreases this summer.

I enjoyed the opportunity to watch real CW contesting first hand.  It is technically challenging and requires skills I do not yet possess and I look forward to progressing in my CW/QRP journey to the point where I can assist Paul in a contest.
That's all for now

So lower your power and raise your expectations

ARRL DX CW contest done for 2016

The roll top radio desk
The ARRL DX CW has come and gone and I took a part time approach to the contest. I was operating single op, non assisted and QRP. The setup is an Elecraft k3 and P3 along with Win4K3suite, N1MM+, MFJ 1788 loop and MRP 40 cw decoding software. I have MRP running in the background as when the CW speeds hit 33-40 it's just easier to use the software. A contest policy that I have is to NOT update any contest software before a contest. There was a new Win4k3suite and N1MM+ update and I resisted the temptation to update. I have had some very frustrating contest's when I have updated software just before the event.  I was able to get on Saturday morning and Sunday morning/afternoon. On Sunday I thought I would get at it early, so I was on the rig at 7am local time on 15m ...BUT... the band was really not all that active out this way. That's a good sign for me as during the next contest I can sleep in a bit and not really miss anything. Around 8:00 A.M local time 15m started to come alive and things were hoping right up until I had to shut things down at 9:30am due to chores. I was back on again around 1pm local and 15 was good and 20 meters had lots of Eastern Europe booming in. I soon exhausted my contacts on 15m as N1MM+ was telling  me "DUPE" for a majority signals on 15m. I was then off to 20m and it was interesting there as the signals were booming in but it seemed I was barely making it, I had to do many repeats. I was off and on until about 3:45 local time and I then decided it was time to shut down. I had a great time making 40 contacts with 33 multipliers for a score of 3960.While writing this post to clear my head head of the dit's and dah's I have Motown booming on the  Studio Beat wireless headphones!

CQ 160m CW Weekend




This past weekend's CQ 160m CW Contest saw the normally quiet band bursting to life with signals stacked up, one atop the other, from 1800 -1870 kHz.


At times it was very difficult to find a clear frequency to send 'CQ' and much of the contest was spent in the 'search and pounce' (S&P) mode. When a clear frequency was found I was able to have several short runs but running for any length of time while in the low power category is not realistic. I think my best hourly rate peaked at '60' for a short time as propagation would improve momentarily ... often, ten or more CQ's would go unanswered and then the next one would have two or three responses, continuing on for several minutes until the propagation would shift. These sudden 'holes' in the D-layer absorption seem to occur when conditions are marginal and it's as if the propagation switch is suddenly thrown from 'poor' to 'really good' for a few short minutes.

Overall, conditions from western B.C. were poor on Friday night and much improved on Saturday night. Although several DX stations were heard and called on Friday night, none were worked. These same stations came right back when called, on Saturday evening.

My 160m antenna is very simple, consisting of a 'half-sloper' and about fifty in-ground radials. Since the tower and antenna are mounted right at the ocean's edge, this year I threw two extra radials into the ocean ... whether or not these made any difference is difficult to say but they certainly wouldn't make things worse.


Because of the proximity to the ocean and the half-sloper producing vertical polarization, my antenna always seems to favor stations at the ends of the single-hop F2 distance ... those along the east coast and into the Caribbean as opposed to mid-continent signals. I often find myself sending several repeats to stations in the central states while those on the far coast will reply on the first call ... even stations that I can barely copy, will often come right back, which seems puzzling.

Overall, about 10 hours were spent in the contest ... ending up with 223 contacts in 51 sections and 9 DX entities. Some of the DX stations worked were PJ2, HK1, ZF2, C6, KP2 and 4V1. Checking my 160m DXCC list after the contest, I was surprised to see that 4V1TL in Haiti was a new country for me, making the contest time well worth it. Claimed scores for this, and any contest, can be viewed on the 3830 Scores website.

As the solar cycle continues to decline, 160m conditions should only get better and better, with the next few years hopefully producing a few Europeans in the 160m log once again.

Skeeter Hunt – NPOTA News

Several things:

First - The NJQRP Skeeter Hunt for 2016 is moving from the second Sunday in August to the third. So please mark Sunday, August 21st on your calendar for this year's Skeeter Hunt.  There are two reasons for this. The most important is that yours truly has an outstanding monthly commitment each 2nd Sunday of the month.  That's the Sunday I go help out at the soup kitchen in the next town over.  I kind of blew that off the past couple of Augusts, and that's not right. There are some things more important than Amateur Radio, and this is one of those.

But hey, the organizer shouldn't go AWOL, right?  (That's how I feel, anyway). So I have moved it back a weekend to the third Sunday in August, where it shall occur forever more.  Another added benefit is that this makes the spacing between Flight of the Bumblebees, the Skeeter Hunt and QRP Afield and the Peanut Power Sprint a bit more even.

Second - I have gotten blessing from Sean Kutzko KX9X to incorporate NPOTA into the NJQRP Skeeter Hunt this year.  Is that COOL or what?  I'm not exactly sure how it's going to all work out. Maybe bonus points for activating an NPOTA unit for the Hunt - or possibly some special "memento" for activating an NPOTA unit during the Hunt.  I'll have to ruminate on that one for a bit - but there's time.



Third - On a personal level, Sean announced some new NPOTA units the other day. This was a biggie for me, because in the Northeast, the Washington - Rochambeau Historical Trail was added. This is the route taken by General Rochambeau's French forces and General Washington's Continental forces as they both marched on towards the siege at Yorktown, which all but brought the American victory in the Revolutionary War.


The Washington - Rochambeau Historical Trail is within a stone's throw from my house - literally. To make this situation even better, there is the Frazee house located on the trail in Scotch Plains, NJ - the next town over. Rather than try and explain the significance of the Frazee house in my own words - allow me to post something from the official Website.


"As the legend holds, after the Battle of Short Hills, General Cornwallis and his troops passed by the house while marching toward the Watchung mountains, located a few miles to the north. Known to the locals as a prolific baker, Aunt Betty was baking bread at the time. Hungry and tired, the troops smelled the bread and Cornwallis approached her stating, "I want the first loaf of bread that next comes from that oven." Betty is said to have replied, “Sir, I give you this bread through fear, not in love.” Evidently impressed by her courage, Cornwallis is said to have stated, “Not a man in my command shall touch a single loaf.” While history offers evidence that Betty lived in the house and did, indeed, bake bread, the story of the actual conversation is not authenticated by primary source documents.  The words allegedly spoken by the principals are found in the earliest authoritative source on the subject, F.W. Ricord's History of Union County, page 513, which is one of the sources cited in the National Register of Historic Places filing that led to the Frazee House being placed on the Register."


I'll have to look onto getting permission to operate from the property that the house is on. If that's not obtainable, there are plenty of other locations that can be operated from on the Trail, right in my local area. In fact, right in front of the Ashbrook Golf Course, is a monument to The Battle of Short Hills.

Stew Perry Topband Challenge





Last night saw another running of the winter Stew Perry Topband Challenge.





This contest is unique in that the usual density of activity on the eastern side of the continent does not necessarily provide an advantage ... contest scores are determined by the distances worked and each QSO will have a different point score, depending on its distance. The exchange is a simple one ... grid locators only ... and from these, the point score for each contact is calculated. From my way of thinking, and many others that I have discussed this with, the 'SP' is one of the fairest contests there is, putting everyone, no matter where they are located, on an even footing.


Today's Sun (courtesy: http://sdo.gsfc.nasa.gov/)
Unfortunately, mother nature, in combination with ol-Sol, conspired once again to provide some serious geomagnetic disturbance and conditions were anything but memorable ... the 'K'-index jumped to a stormy '5' right at sunset. I seem to be saying this a lot of late, but the sad fact is that sun has been extremely active and punishingly geoeffective as it winds its way down from a rather unnoteworthy peak. To add more mystery to this already quirky cycle, its downslide would make any 'normal', highly-active cycle, stand proud ... the strong slide down does not seem to match the wimpy low-level peak, observed a few years ago.

From here, operating in the 100-watt category, it was a struggle to work the normally easy single-hop stations, with no signs of the central states for several hours after sunset. Several east coast stations were worked towards midnight for the nice 12-point per QSO scores, but truth be told, almost all contacts were a struggle with many stations needing several repeats just to get the call or grid.


My half-sloper antenna and radial system is located right on the edge of the ocean, looking to the east, and its already low takeoff angle is enhanced with ~ 6db of sea (horizon) gain, making it a poor antenna for anything within the first-hop region ... after that it really seems to comes to life.

At 12:15 a.m., I pulled the plug, ending up with just 97 QSO's and 555 claimed points, way down from normal. Other claimed scores can be viewed on the 3830Scores.com website.

My best DX is usually JA but this time was KH6. The SP is always fun, but better conditions would have really made it a blast ... hopefully next year!
