Sweepstakes 2008 CW Score

Scores for the 2008 CW Sweepstakes have been published on the Web. The Sweepstakes LCR report is always worth looking over, since my error rate is still far too high on CW. For 2008, it looks like 44% of my errors were on the check number. The errors on the exchange was about 45%, and I busted only four callsigns. The score suffered dramatically, but I showed some incremental improvement over the 2007 Sweepstakes. I didn’t match the improvement in error rates I managed in the 2007 IARU, but it was better than the error rate of the 2007 CWSweeps.

The callsign copy needs to be 100%, but I made progress in that area over 2007.

The big problem seems to be busts on 7&8 and 2&3. Not a surprise. That mistake is accounting for the bulk of the cross check number busts. It is also the biggest problem in the exchange busts, where the year license is busted because of 7&8 or 2&3 busts. By correcting this copy error I will clean up almost 80 percent of my over all bust rate.

The other remaining errors are a mixed bag. There are several transposed digits in year licensed(e.g., where I logged 67 instead of the correct 76). This is a typing dyslexia that I often can catch as it is happening. So more attention to detail is needed when typing.

The rest are just generic inexusable errors. The callsign busts are fixable. “agn? ?”

Overall, I’m disappointed in the lack of overall improvement in clean copy. The score suffered mightily. But it still holds up as my best ever CW score, despite the inadequate copy. Besides, it was a blast.

K8AC, AA4NC, and N4AF all won their categories here in the Roanoke Division. Cool.

2009 ARRL DX CW

No goals to acheive for this one, just some fun spinning around the bands.

I am sorry I missed operating on Friday night. Saturday night turned up a lot of EU countries on 80m. I’m sure there are a few new ones, since I’ve seldom really worked 80m as seriously as I did Saturday. The side effect was neglecting 40m, as well as missing out on Friday evening.

Started in the late afternoon Saturday on 20m. After the first 15 or so S&P Q’s, I found the NY4A ops and parked to read their mail around 19:50z. It’s probably the easiest way to get a good idea about propagagtion, because Howie has a great signal into EU. Normally, I hear only every third or fourth station, sometimes less.

But Saturday was different. The 100w EU stations had good signal strength, and over a 10 to 15 minute period I was hearing almost everything the NY4A op was working. Hmmmmm.

Sliding up the band, I found a hole around 14081 to try running. I had a nice 40 minute run, then the floor seemed to drop out. The run rate wasn’t fantastic, but it was better than S&P, and it was good run practice. Logged 35 Q’s, mostly northern EU. Later on, there was a JA on 14023 who was about 559 here in central NC. He had a huge pileup, and could not hear the tin whistle from the KazShack. Seemed to be working the Left coast and stations in the Black Hole. I never found any AK stations. A quick spin across 20m at 0100Z turned up KH7S. At that time, he was the only station I was hearing, but he was solid copy. It seems likely that his copy on W4KAZ was somewhat less robust.

Getting a run going on 40m and 80m was just not accomplished. QSB was a problem on 80m. A G4 that called in on a run gave up on it. The QSB got the suffix of his call every time. But for the time I had available, the S&P was fun. I didn’t turn on the packet, so it was fun hunting the pearls. I don’t know how conditions seemed to the big guns, but it was quiet here. Propagation seemed pretty good on 20/40/80. 160m was quiet too, and I was able to work several of the Carribean stations. Did not stay up late enough to try to get the EU sunrise.

The Good: 20m condtions seemed slightly better than they have been, but still nothing fantastic. Working KH7. New DX on 80m. 160m antenna seems to get enough signal out to at least be heard.

The Bad: Missed operating on Friday night. Unable to establish a run on 80m. Insufficient patience for running at a slow rate.

The Ugly: Flubbed exchanges.

To Fix: Mostly the lid operator. 😮

2009 CQ 160m CW

Totally unexpected results. This was nowhere near a serious attempt to maximize the score, but rather have fun playing with the K2 on160m. It turned out to be a lot more fun than I really expected.

I did not operate long Friday. I was just too tired. But I was on long enough to realize the conditions were very good. The noise level was very low on the transmit antenna. It was possible to turn on the pre-amp for the weak signals. The big surprise was that most of the weak stations could hear me. Yikes.

But it just got better. I planned the day better on Saturday, and was more prepared to stay up a bit later to play more radio. Conditions did not seem quite as good as Friday, but the noise level was still low. I worked some new states for 160. Even more unusual, I also worked 14 European stations. Their signals seemed to come up with their sunrise. I knew I could hear them, as I had been listening to a couple of run stations, and I could copy most of their EU QSO’s. Tuning around with the K2, I was able to find several EU stations calling. The booming US signals made some of them too hard to copy, but several others were easy copy.

Low and behold, a handful of those were also able to hear the 100 watt tin whistle. Way fun. Apologies for the guys that really had to struggle to copy my weak signal, but I sure do appreciate the effort! Some of those guys must have really good RX antennas, because they didn’t miss a beat, and got it on the first try.

So I spent the last hour digging through the US QRM for the EU pearls. The K2 is really an S&P operators friend. With the filters cranked down to 200hz, it was easy to find the stations. Not so easy for them to find me, but that is an antenna/ERP problem unlikely to change soon.

The Good: The antenna repairs worked. The extra radials on the 160-L probably didn’t hurt either. Currently 18 radials, between 16 and 45 ft long. The K2 really shines for S&P. Conditions seemed as good as I have ever heard on 160m, but my experience down on 160m is very limited. K2 is generally much better at keeping NT4D out of the front end than the FT-920(exception below). Worked RK2FWA…on 160m! Finally worked ON4UN on 160!

The Bad: Missed a golden opportunity by not planning to operate more. Discovered that NT4D causes a mild overload when listening on the xmit antenna with the K2 pre-amp turned on. Discovered an NT4D image 20kc below his run frequency. Gotta get with Jay and do some testing to see if it is an artifact generated in the K2, or if I can hear the same image in my FT-920. (NT4D is a nearby neighbor, close enough to be inside a 500 meter multi circle. We’re gonna pull the trigger on that one day)

The Ugly: Nothing found – yet.

2009 NAQP SSB January as NC4KW @ N1LN

First, many thanks to N1LN and N1YXU for the invite, the great company, and the hospitality. The station and the setting are wonderful, and I can’t think of a better way to spend an afternoon of radiosport.

The contest operation itself did not hit the goals I had in my head for us. I really expected to beat our own score from August, but we did not. We actually came up quite short.

The 20m band was really abysmal. I started out the contest on 20m. After the first 40 minutes, the “run” dried up, and never was re-established. The first two hours ended with only about 45 Q’s on 20m, woefully inadequate. I knew it was going to be bad when NT4D lapped the QSO count the third time on the 40m station. He had 100+ while the 20m station was stuck at 33. Ick. No one else had any better luck on 20m either. Just terrible. 15m was far worse. I moved there to pick up the CA mult and 6 or 7 CA QSO’s. N1LN picked up another mult and another 6 or 7 Q’s on 15m a little later. 11 Q’s total.

10m? Ha.

The good news was that 40m/80m/160m all supplied a steady stream of Q’s. With 20m shut down tight, the “happy hour rush” was pretty slow, as 40m had been milked pretty thoroughly by 5:00pm local. I did manage to notice it was twilight, and picked up a handful of FL, GA, and AL on the low 40m beam. But as soon as that finished I was beginning to work WA and OR on the top of the stack. 40m was long at sundown. NT4D abandoned the futility of 20m to start 80m pretty early. When N1LN took over the 80m run a little later, the rate had become pretty good on 80m. O’course, 40m had petered out.

80m was fairly productive for the rest of the contest, and there were a few good runs on 160m later in the evening. The term ‘good’ in the context of this operation was a best combined 60 minute rate of only about 125/hr. The three and ten minute rates hit 200 several times, but only for short intervals.

The company was great even if conditions for HF were not. I am learning a lot from N1LN and his station, and I really appreciate the opportunity to see the station in action. Time well spent.

Well, that sure was fun. If I were feeling better, I think I’d have made the 400 Qso goal, but as it sits there are 11 Q’s missing. But that is closer than I genuinely expected to get to the 400Q goal.

TheGood:
This contest went very well. The very high point had to be being called by UT5UIA in the last minute of the contest on 80m. I don’t actively pursue much DX on 80m, but it is obviously there. I hear lots of DX during DX contests, but have always assumed they were probably running power. The noise level on 80m was very low during the last half of the contest. Great 80m conditions.

I also had a few interesting QSO’s on 40m phone. KH6FI was so loud I thought he was in the mid-west.

Of the pre-contest goals, I was able to meet most of them, at least to my own less demanding standard. I fell short of the 400 Q goal by just less than one percent. Given the interruptions, my claimed 9.5 hours is more than I was actually butt-in-chair, having to get up several times for errands. Those times are counted as operating time, since the breaks were less than 30 minutes. I also had to take a break during the evening rush to meet the two hour off requirement. So I expect those two goals are dependent. The good news is that I didn’t get tired and conk out early.

Running at 24wpm worked out fairly well, after a bit of initial fumbling around. When the rush hour arrived the grey matter was copying well enough to keep up with the run. I found I was needing fills again before the end of the contest, but I was mostly able to keep up.

It was fun to run.

TheBad:— The 160m-L needs work. It is still showing a high SWR. Debugging needed. 20m had a high local noise level. It sounds like there may be something in the neighbor’s new addition that is generating RFI. There’s not really a more suitable location for that particular antenna – unfortunately. Running on 20m is mostly wasted effort, even in NAQP. S&P is fine. Not much activity early in the contest.

TheUgly:— None this time. I’m sure Murph is out somewhere looking for new tricks…

2009 NAQP CW – Goals

Today’s introspective question is “What’s a reasonable goal for this weekend’s NAQP?”.

Given the current level, I’m not sure 500 QSO’s is reasonable for a 10 hour contest. Thats where I would to get, but probably not for 2009.

So more modestly:

  1. run stations at 24wpm
  2. shoot for 400 QSO’s
  3. shoot for putting in all 10 hours, despite the illness
  4. Even spread of Q’s on 20m/40m/80m, and pick up mults on 15m & 160m if possible
  5. Move the run frequency lower if possible

The first goal will lead to the second, but only if I manage the third. The reset is icing. We’ll see.

edit 2009-01-08, Stuck in the past….cuz these are 2009 goals….

N4A Treasure – 2007 IOTA NA Expedition Plaque Arrives

In the post on Monday was an unexpected surprise, the 2007 IOTA N4A Expedition plaque.

Love it. I might even let N4YDU have it. Or at least send him the link to the photo.

2008 CQ WW DX CW

This is a contest that I like, but usually miss because Thanksgiving weekend is usually booked solid with other activities. But there were a couple of open hours both Saturday and Sunday evenings, so the K2 went out for another spin. RX conditions seemed good, despite a cold front and line of showers in the area. Propagation was about what is expected at the bottom of the cycle, fairly crappy.

On 20m, I never heard any SP’s, and the few DL’s I could heard were very weak. Even allowing for the time of day, that was a bit unusual.

There were a bunch of JA’s on 20m Saturday night, but they could not hear me on either the dipole or the 160m inv-L. They were not very strong on my poor antennas, but there was little QSB, and they were easy copy.

I used the packet cluster again, since I was just dorking around. There was good copy on stuff I have not heard in a couple of years, but had trouble hearing the DL’s, and I never heard anything from Poland. Worked an F6 on 40m, but never heard any on 20m. The AL’s were S9+ just after local sunset on Sunday night, right before the JA’s started popping up on the packet cluster. Despite a ton of JA spots Sunday night, none were as easy to copy here as the hand full I heard Saturday night. Heard weak ZL’s working the west coast, but they never came up above a whisper here.

The best prize was working TA5KZ. I thought his call was too cool to miss(given my own), so I hung in his pileup until I got a hole he could hear me through. He was working mostly EU stations, and I think the “W4” was a break in his rhythm, but he was able to hear me. Sweeeet! I think the last TA station I worked was on 10m, back when the sunspot number was over 100.

Leisure Reading – PileUP!

I’ve seen his was announced somewhere before, but now I’ve got the link. The Finnish contest magazine PileUP! is available in PDF format, and has articles in both English and Finnish. I’ve only browsed a bit so far, but it is an interesting perspective on RadioSport, given their drastically different geographical situation. Good reading.

2008 ARRL Sweeps SSB

Yikes. That was a bit more like work than play, but it got better as the contest progressed.

Events leading into the test did just not come together. I missed all of the practice and audio check sessions leading up to the contest. Once the test started – too late! Also had the beginnings of the common cold during the day Saturday. Got worse on Sunday, but the voice held up.

The game plan was to start on 20m and 40m with about 60 minutes of S&P. One thing led to another, and the first QSO wasn’t logged until about 45 minutes after the start of the contest. That probably cost a few possible mults, but none that I didn’t pick up later. When I migrated to 80m, I got a quick call and a report of bad/muffled audio from someone I had worked on 40m. I suspect that in adding the 160m module to the K2, I went too far in adjusting the output filter. Since I expected the bulk of my QSO’s to be on 80m, I decided to move back to the FT-920.

Moving to the FT-920 required moving all of the audio and antenna connections. That took a bit longer than it could have if I had been feeling better. Then I had to dork around to get the audio levels from the sound card an the mike equalized on the FT-920. This is going to be a bigger problem if I ever seriously try SO2R, because the level out from the sound card needs to be set much higher for the FT-920 then for the K2. I guess a simple resistor will suffice set the level lower for the K2.

Anyway – transfer to the other radio and associated dorking around put me about 90 minutes later into the contest. 80m was beginning to pick up, but I was able to squeeze into a 4khz gap I found, and establish a decent run. I pulled the plug a bit early, and was behind where I wanted to be.

Saturday morning was spent running 40m and S&P mults on 20m. Saturday afternoon was a real mixed bag. I at no time received any answers to CQ’s on 20m. Too crowded for a LP/dipole station to be heard.

Sunday evening was back to 80m, plus the occasional foray off the band for a possible mult. Picked up OK and WTX on 40m that way.

I was happy to break the 500 QSO point this year. Using packet helped me get six extra mults over the 69 in 2007. That brought the point total up to almost equal the 2007 level. Good enough.

The Good: The FT-920 was on hand to fill in for the K2. New computer sound card was fine. 80m was floor to ceiling full of QSO’s.

The Bad: Probably the K2 problem. Since I’m almost certain it was self induced, its not a show stopper. And it seems fine on CW. Need to do some testing, and re-align for 80m.

The Ugly: Hmmm. Gotta be the head cold. Luckily, maximum “Ick” was not reached until Monday.
