Last year, I managed to scrape together some equipment funds at work to buy a small spectrograph system for studying atmospheric light emissions (airglow and aurora).  A co-worker secured the funds and contacts for us to install it at an observatory in Greenland.  Because we need to make the measurements at night, and because the instrument was delivered in early December, we made immediate plans to go to Greenland as soon as possible.  (Sarah is certainly laughing at this point because the plans were actually far from immediate and we bought our passage just over one week before departure.)

Greenland is only a short (4- to 6-hour) flight from the NE U.S., however the only route that operates in winter (and indeed the only commercial route) is on Air Greenland via Copenhagen, which operates four round-trip flights per week in winter.  This turned getting there into a two-day affair of perverse travel arrangements totaling over 12,000 air miles to go about 4200 miles round-trip on the great circle.  I met my co-worker, a United Airlines devotee (myself an American Airlines devotee), in Copenhagen and we flew to Kangerlussuaq (Sondrestrom) on Air Greenland.

One of the things that strikes you about Greenland as you approach Kangerlussuaq is how otherworldly and remote it is.  Kangerlussuaq is the site of the former U.S. Sondrestrom Air Force Base, and one of two runways (the other is at Thule) on the island large enough to accommodate aircraft capable of flying to Greenland from abroad (this is a mild, although amusing exaggeration).  Air Greenland has its hub there, shuttling passengers off to towns around Greenland on twin-engine turboprops like the Dash-8.  It is, as our host explained, “…not your typical Greenland town.  It is far inland at the end of the fjord and not on the coast.  The only reason it exists is because of the airport.”  Fuel and supplies are all brought in from outside.  Like most current and former U.S. military installations worldwide, it is reliant on diesel fuel for its on-going existence.  It’s sobering to be someplace that is totally unsustainable, although one might argue similarly of many U.S. cities, but I digress.

Kangerlussuaq is also near “the dog line,” north of which sled dogs are very common.  Here is one of the two road hazard signs we saw while driving around…dogsled crossing:

The instrument set up easily the first afternoon and we were able to collect some data with it that night.  As we were setting the instrument up, we heard reports of an Earth-directed CME from the Sun and hoped for aurora over the next few days. We were not disappointed…

The second night, I stood “aurora watch” in the cold while my warm-blooded co-worker processed the previous night’s data.  Soon, I saw some faint cloudy white sheets way down on the horizon and I ran back in to alert him and retrieve the camera tripod.  This photograph was taken facing toward the east southeast.

And, the 3.5-MW peak L-band incoherent scatter radar was running.  The dish is blurred because it is moving.

And, here is a shot of my fan dipole strung up on the DK9SQ mast.

Speaking of radio, I did manage to make a few QSOs as OX/K8GU on 17 meters, but not as many as I would have liked.  The combination of high absorption in the auroral oval (mostly to our south during our stay), little sunlight, a poor low-angle shot (required to avoid the auroral zone) to North America, short openings, and the fact that we were well-occupied with work for the four days we were there conspired to keep my contact count low.  QSOs will go into LoTW soon—the certificate was issued yesterday.  I have not yet designed a card, but there will be a special card.  Thanks to those who did contact me.

You’re kiddin’ PE4BAS goes QRO. No, it can’t be. But a picture says more then a 1000 words! It has to be true. I just had the opportunity to buy this RM KL500 amplifier very cheap on the club evening last friday. I thought what the heck, I just like to experiment. This amp is rated 600W (!!) out with 30W SSB in. Well I don’t recommend that at all, as it will get very hot. At first I connected everything to my FT817 and did a 5W input, the amp was not going to TX, was it broken? So I was a little angry about that. I wrote one of the clubmembers to get the call from the amateur that had sold it so I could get in contact with him. Then it strikes me that there was a extra connection made on the back side. The electronic diagrams were delivered with it and from that I understood the internal VOX circuit was bridged. I just had to connect this connection to earth or neutral via PTT to get it on TX. After looking inside it was clear to me the extra BIAS mods found on the internet were already made in this amp. Anyway, just to be shure I connected a old CB radio with 3W instead of my expensive FT817. With the KL500 on the dummy it did already 100W out full power. But it took 30A of current already. I don’t want to test it any further as that was more then enough for me. I guess it does about +200W out with 10w in? Too much for my needs. So I will sell this one after I tidy it a little and make a proper connection for the large current supply. After that I will try to test it once more with 10W input and then sell it. 

So I’ve been to the local radioclub last friday and collected my QSLs from the bureau. They have a special PE4BAS tab in the QSL trunk now, so they were easy to find. 2 QSLs were special to me. The one from ON2PCO as I remember him well. He was using 10W with a FD4 dipole inside the house and was surprised to work me on 80m in the PACC. And the QSL from JW/PA0ZH from Spitsbergen, Svalbard. I didn’t work them with EME but on 20m SSB. Although they were QRV with EME, I think they made a lot of operators very happy. 

Today I listened for HK0NA once again. I guess luck is not with me as I could only hear a very weak sometimes readable signal on 15m. The rest of Europe seems to have very good propagation as he worked one after the other. Same for TO4M who was just readable on 10m, he worked a lot of Europe but after calling for half a hour I just gave up. I tried for a Brazilian station who was RS58 here, but even he didn’t hear me. Time to leave the radio then and do some other things. I hope propagation will be better with the PACC on……9 days to go.

A packet arrived from China this morning containing a 16×2 LCD module which I purchased for the absurd sum of £1.93 including shipping. That wouldn’t cover the postage from a UK supplier. I don’t know how the Chinese do it and make a profit.

I bought the module with the intention of using it to make a user interface for my Parallax Propeller beacon. Having ordered it I was not sure how to interface the LCD to the Propeller so I chickened out and ordered an LCD UI module from Gadget Gangster. This is rather more expensive (though still a reasonable $29.99) but it includes a 4-way + depress button for menu navigation, plus a separate red button. It plugs straight into the Gadget Gangster board.  I reasoned that even with the hardware sorted the software would be enough of a challenge.

I have rather ambitious plans for this beacon. Perhaps over-ambitious. After reading Alex G7KSE’s blog post about his Arduino based MSF 60kHz receiver I’m interested in interfacing one of the inexpensive MSF receiver modules to the Propeller. I could use this to display an accurate clock and also to control the start of WSPR beacons. As I’m a bit of an accurate time nut and have two radio controlled clocks in the shack (and a radio controlled watch) it is really no trouble to press a button to start the beacon at the beginning of an even minute and then keep time from there. But that isn’t the point really, is it? What could be cooler than a shack clock that is also a WSPR beacon?

This microcontroller stuff is new to me and I have a lot to learn about it. One question I have is what do constructors who use Arduino boards or similar things like the Gadget Gangster do when they want to make a finished project? Do you just buy another development board to use for the next project, or are there simpler boards with just the microcontroller and its essential ancillary components which you use for the final version? I guess I’d still want the ability to update the software (firmware?) so there isn’t much of the Propeller Platform board that I wouldn’t be using.

Great success in the 80 Meter Fox hunt tonight, due to the great ears of Dave N1IX and Tom KV2X. The fact that Dave lives in New Hampshire and Tom in New York was to my benefit as these are pretty easy hops for me on 80 Meters.

I went to the ARRL’s Web page today and downloaded the Diamond DXCC (DDXCC) Scorecard, which is an Excel file that you can use to keep track of the entities that you have worked towards the award.  So far in January, I worked 15 entities that count.  So I am 15% of the way there.  Not a terrible start and we have the major DX contests still to come – the ARRL DX Contest coming up in February as a matter of fact.  I don’t know if I will be able to achieve the certificate; but it is a worthwhile and fun goal for the year.

15 Meters did not seem as active this morning as yesterday morning.  I did manage to get Cuba in the log, working CO6WD before heading off to work.  Down the band, there was a huge pileup, spanning many kHz; but for the life of me, I don’t know who everyone was trying to work.  I couldn’t hear the quarry (and I didn’t have the DX Cluster up on screen); but I would assume it was most likely either HK0NA, TN2T or perhaps VP6T.  These seem to be the three “biggies” right now.

The more that I am on the air this year, the more I am coming to realize that “Happiness is listening to a good fist”.  I hope that I fall into that category; but I can sure tell you that there are a lot of folks out there who don’t seem to.  And that’s a shame.

The problem seems to be spacing and “hurrying up”.  And I think I make that mistake myself from time to time, especially if I’m a bit tired and not paying attention to what I am doing.  A long time ago, my Mom gave me a little angel that hung from the rear view mirror in my car that said, “Never drive faster than your Guardian Angel can fly”.  I think we Morse Code enthusiasts should have something along the same lines.  ”Never send faster than your fist can send” (or something like that!).  If you get sloppy, or take for granted what you are doing and don’t pay attention to the task at hand, you’re going to sound pretty awful.  And that’s not fun for anybody.

Sending good Morse is an art.  It is a deliberate act that takes concentration and diligence and practice. Spacing is just as important if not more important than anything else.  It’s a good thing to remind ourselves, from time to time.

QRP – When you care to send the very least!

Lets play radio

This past Sunday I sat down and got some radio time in, it seems there is so much that can come up to pull me away from some K3 time. I wanted to make an effort to sit at the rig today, relax and call CQ on 14.060 and to see what happened. I cranked the K3 up to 5 watts and let the CQ ring out over the airwaves!! It was not long before Peter KG4GR came back to me he is located in  Iowa. I was exspiraneing some type of AC QRM most likely from the 230KV hydro lines at the back of our home. The noise blanker on the K3 seemed to take care of it but Peter was in and out and I got the impression I was the same with him. Maybe
it was this huge solar eruption of the sun the other day that was still having it’s affect on the bands. In the past I had  checked out the solar forecast before hitting the air waves but I found it used to cloud my ambitions. So now I just go for it without checking or if I do I don’t let it affect my operating time. Anyway………Peter’s signal gave me a chance to try out the K3′s APF (audio peak filter again. I have had some troubles in the past with getting this feature just right and it does I am told take some practice. Well it sure did help with Peters signal. I had a nice QSO that had to be cut short as another station unknowingly was calling CQ. I then gave things a little rest and started to read and comment on some blogs I still had the rig on and the head phones around my head just in case China happen to be calling CQ……HI HI. Once again I called CQ and WD9F/QRP came back to me…..and this QSO was a very humbling experience . For some strange reason my brain went into neutral, I just could not get my ears around the /QRP in the Woody’s call!!! I asked him for a repeat…still did not get it and at the end of each transmission I would try his call and end it with ?. Well Woody was very polite and patient and dropped the /QRP and stayed with his call only. Once he did that it clicked what was going on. Boy did

WD9F/QRP

I feel foolish and as the QSO went on my foolishness bloomed. I was a bit flustered once I figured out his full call. Then it happened the QSO went off the standard exchange and into a CW conversational  QSO. Woody spoke of how he reads my blog and enjoyed my last post about the late QSL card. That was the end of my brain and the connection to my left hand at the paddle!!! It was like the keyer was working on it’s own and not in a flattering way. Woody was very polite and weeded through my if you could call it “code”. All I can say is nerves got the best of me. Oh well just have to keep plowing along and the weekend is coming and time to practice the brain vs left hand communication again.
