Off With a Bang

As promised, KL2R is starting 2018 with great gusto. Several contests have helped the count, but so has the International Grid Chase and a quest for Worked All States on 80 meters, which will also give us 5BWAS. That means we're reasonably active shooting grey line to DX in the morning and evening. Europe, JA, VK, and North/South America are proving to be very workable on FT-8, when openings can be very brief (minutes), but long enough for the new mode. As of this date, we have 40 LoTW QSLs on 80 WAS, and 21 DXCC. A highlight was working Francesco IK0XBX after trying for about three weeks.

This brings me to WPX RTTY last weekend, which was a big blast. Saturday was busy in the shack. Dan KL1JP stopped by late morning and proceeded to spend several hours running on 20 meters, picking up on an early opening that really didn't abate until mid-afternoon. At that time John AL7ID, Paul KL4ET, and Pete KL4IT arrived for a demonstration and tutorial. It was a good time to give the latter two an intro to the shack, as we switched to 40 and 80 meters and the rates slowed down. Pete is a newbie to contesting, but Paul had some experience with WL7F/KL4SD SK running low power. In the end, 900 QSOs and 907k points was more than double the previous best from KL2R.

What Happened in 2017?

I have to say that the past year has been nothing to shout about, at least as far as signals from KL2R have been concerned. Re-cabling in the shack and building a solid SO2R with new hardware from Microham basically came to a screeching halt. Contest opportunities and team members dried up, life basically getting in the way of a hobby.

The results are clear from log statistics from 2017 thanks to Clublog.
It is the lowest QSO count in a decade. The only year lower was 2006. We only formed the Two Rivers Contest Club in the fall of that year! So we go down in 2017 as not a failure but rather a station in transition. The to-do list is substantial, but so is the commitment to get it done in 2018.

In Memoriam: WL7F SK

Just before Thanksgiving, Wes Jennings WL7F, age 52, was killed when his snow machine was struck by an SUV near his home on the Parks Highway about 25 miles west of Fairbanks. The contest community has lost a good one. Wes could be a royal PITA, but I admired his energy and tenacity. He was brilliant and quickly leveraged his prime RF location into a top contest spot. Off grid. Low power. He took many risks, from free-climbing his tower in the middle of winter to the accident that killed him. He was a wild man, and I shall miss him immensely.

Field Day 2017

Naturally, FD propagation conditions were not very good, but that didn't stop an intrepid dozen from setting up and giving it ago under the KL2R banner. (KL7CDA was the GOTA station.) We picked a new venue at the Pleasant Valley Community Center, which is just about 7 miles east of the club station. Many thanks to John AL7ID for arranging to have the building during the weekend. Although a tri-bander was erected, only 20m proved workable. Dale KL7R rocked satellites handing out AK for a lucky few. The 6m setup really didn't prove helpful, but it wasn't for lack of trying.  Many locals are on 6m FM now.

Oh, the joy!

Busy Bobcat

The tower is approximately 100 feet from the shack, and for years the cabling was only half-buried and subject to breakage. We also host the local wireless ISP equipment on the tower.  A snowplow snagged the internet cable and a coax in January. Laying new cable in thigh-deep snow at 30 below is not a great thing to be doing. A plan was thus hatched with the ISP owner to properly trench between the tower and shack just after Field Day. He has some dandy toys, not the least of which is a Bobcat skidsteer with proper attachments.  It was a 14-hour day, but conduit and spare underground cables were the result.





Time Flies Like a Banana Peel

Seriously, the time has slipped past way too easily since the last blog post in March. Here we are in early October, and one might think there has been almost no radio action since then.  Well,, nearly, but not quite.  Here's part one of the re-cap:

Visalia DX Convention

This was a riot, although a smaller gathering than in 2016, which was some kind of record. Without checking official numbers, I heard roughly 750 people attended this year. Last year it was closer to 900-1000. In spite of having a bout of flu, I attended more technical and contesting-oriented sessions. IMHO the DXpedition sessions become incredibly redundant: "It was hard. We made lots of contacts. Send money."  But I digress. See what you missed: IDXC 2017 Program. The dinner was well-attended, and many laughs were had, both intentional and unintentional. Our table mates were from Canada (VE3CFK and XYL), Colorado (N7VZ and W7UM), and Colombia (HK3W). Fun!

Propagation Sanity Check

This morning we received an email from Finland!  It's always nice to hear from our "neighbors" across the north pole.  I know we share a common bond when it comes to tough propagation.

Hello, Sirs.
It is quite foolish to ignore JT65 spotter on.
The whole of Europe called on you.

None of the answer does not come from there.

OH4SS, Matti

I was certainly sorry to miss the opening.  

So it would seem Matti is implying one shouldn't run JT65 spots to PSK Reporter if not in the shack. Now that's an interesting point of view, and one I haven't encountered before.  I think we have a little disagreement here with Matti, but maybe there are others out there who feel the same way. 

"Foolish"?  Let me explain my rationale.

Followers of the blog -- are there any? -- will know there are special challenges the ionosphere lays on us in the high latitudes.  What they teach you in radio school about propagation being basically reciprocal is total nonsense above 60 degrees or so.  It's actually hard to figure out when openings may occur.  The second element to this puzzle besides geomagnetic instabilities is the rapidly changing daylight in the Far North.  In Fairbanks, daylight changes 6-7 minutes per day throughout much of the year.  That has huge implications for HF, as one week is literally completely different from the next.

Sooooo...here at KL2R we make frequent use of spotting software and other tools to monitor the bands. That includes CW Skimmer reporting to RBN and WSJT-X reporting to PSK Reporter.  The data is helpful to other hams who are anxious to see when the bands are open to Alaska.  What's not to like?

The other reason we frequently run receivers and spotting software when the shack is unattended is to gather data for serious technical analyses.  The data sets are useful for comparing station performance, for instance.  JT65 actually yields quantitative results on received signal-to-noise ratios from various locations.  We can compare, say, AL7ID just a few miles away.  Even better, years of study have clearly demonstrated the myth of reciprocal propagation.  Approximately 80% of the time, the KL2R signal SNR will be about 6-10 dB worse at the remote station than received here.  What that means in practical terms is that when we receive JT65 at around -15 dB (good by most standards), the other station is likely to receive us at very marginal levels, if at all.  So there you have it.

Finally, let me just say presence on PSK Reporter is not the same as a call for CQ.  The spotting network does not substitute for actual RF.  So who's "foolish"?  I suggest those who would call a station without hearing their signal.  Whatever the mode, many Europeans have a bad habit of throwing out their callsign into the ether in the hopes the DX will log them, like a message in a bottle. It's remarkable that within hours of working a pileup I will get requests by email, like "Please tell me if I worked you."  Seriously?  If I worked you, you would know it.
