Operations from the South Sandwich Islands (Thule) has caused a lot of excitement on the bands over the past ten days ... but for myself, it was more of a last-minute frenzy, which I'll elaborate on later.


The expedition, composed of a crew of 14 operators from the 'Intrepid DX Group', left Port Stanley in the Falkland Islands aboard the MV Braveheart, on a 38-day roundtrip to South Sandwich and then to South Georgia ... two of the rarest DX entities on the planet, and by any standard, not the easiest places to reach!

South Sandwich was on-the-air from January 18th to the 25th, when a sudden turn of events put an end to the operation from the island. Not long after they suddenly disappeared from the air, this bulletin appeared on the DX newswebsite:

Today at 21:20 UTC, Nigel Jolly, Braveheart owner, declared an emergency and ordered to VP8STI team to cease all operations and return to the ship.

A large ice flow that had broken away due last nights storm starts to block the entrance to the Bay where they were camped. There was strong potential for the ice flow to prevent Braveheart to get them.

Team is now safely aboard the Braveheart and they are moving away from Southern Thule Is. All the equipment and personal gear is still on the island. They hope to return to camp site during next good weather window.

Once they retrieve their equipment, they could make a determination as to whether they can proceed to South Georgia to do VP8SGI as planned.

The latest word sounds very hopeful:

Finally yesterday, team was able to collect all gear from Thule Is.
All team members are OK and they are on the way to South Georgia where they will arrive after three days sailing.

They will try to be on the air during eight days as VP8SGI.

Personally, I want to thanks to all who send support messages to us, expressing their concerns about VP8STI team situation.

I had been aware of the expedition but had not been paying too much attention ... after checking my master DXCC checklist and finding that I had already worked South Sandwich on 160m, several years ago, I didn't really need it. I'm not sure why I checked my list again on the 25th but when I did, I realized that I had really messed-up ... it was actually South Georgia that I had worked on 160 and not South Sandwich! I had never worked South Sandwich, on any band, and it was one of the last 9 entities that I needed for having worked them all ... big mistake.

I soon realized that operations on South Sandwich would be coming to a screeching halt at any moment and scrambled to see where they were presently operating. Unfortunately they seemed to spend most of the day (25th) on the WARC bands, for which I have no antennas ... I really need to hang a 30m dipole up in the trees one of these days for situations just like this.

As darkness approached VE7 land, I began seeing a few spots for them on 20m phone, not my favorite mode, nor the most efficient for working pileups.

Zeroing-in on their frequency found them with a nice 5x7 signal on 14.180kHz and listening from 14.235 - 14.245kHz. The operator was working North America by call districts and when I tuned-in, was working "Ø" 's. He would work ten stations and then change. He started on down the list, calling for "9" 's and then "8" 's but when he had finished with them, he called for "1" 's ... hmm. Perhaps he had started with "7" 's before I arrived and was working his way through the list once again.

It seemed to take forever when he had finally finished with the "6" 's and his signal was now considerably weaker ... "7" 's should be next. But no ... it was even better!

Luckily I had been following his tuning technique as he worked through the pileup and was able to track his listening frequency as he worked his way from 14.235 to 14.245 and back again. I had my transmit frequency already set on the frequency of the last "6" that he had worked ... when he called for "any VE's?" ... as luck would have it, he came back on my first call, not only making my day but making my week!

After a bit of a scare, I was very fortunate to work them on what turned out to be their last full day of operation, as they left the air, and South Sandwich, after only a few more hours of operation.

From now on I'll be checking my list much more carefully.

I’m happy to report I’ve been involved in adding three new hams to our ranks in the past two weeks. I had lunch with one today and we got to talking about radios. He wants to get on the local repeaters right away, and so we started talking about analog versus Fusion versus D-STAR. When we got to the topic of price, I was blown away to find out he had found brand new D-STAR ID-51 VHF/UHF handhelds for $299.95 shipped. It’s a long way from a $20 Baofeng, but to have the ability to talk around the world on VHF or UHF for $299.95? That’s a pretty good deal.

The snow plows came through to clear our street.  Even so, they never really plow the entire street. They clean it up for sure, so that you can travel safely down the road, but there's always that snow plow residue on the sides of the street. So, until the snow melts substantially, I can't park on the street, as I usually do, there's just not enough room to park and still have space for other cars to get by.  That means I have park in the driveway. Since I generally get home last, I have to get up and move my Jeep when my wife Marianne has to leave for work at 5:00 AM (I've mentioned - she's a nurse).

So this morning, after moving my car for her, I made some coffee and headed down into the shack. I had about a half hour before I had to shower, shave and get dressed for work. I figured that maybe, just maybe, I'd hear K5P, as this is their last day on the island, I believe. And sure enough, there they were on 80 Meters, calling CQ!  And from the rate they were answering stations, you could tell they were listening for ATNOs - stations they had never worked before (which would have been me!).

They were decently loud - about 559 with QSB on 3.530 MHz with QSB.  Even so, this was the best I've heard them throughout the entire DXpedition. I put the KX3 into "Dual Watch" mode, so I could figure out where they were listening, and then I fired up the KXPA100 to 90 Watts and jumped into the fray.

Then some idiot proceeded to come onto their QRG (the frequency they were transmitting on) and began to send an non-ending string of S9 dits, totally obliterating them.

"You can't work 'em if you can't hear 'em."

Sigh.

As has been the case for much of this winter's DX season, LF conditions were very erratic during this past weekend's CLE NDB-listening event.



Geomagnetic activity fluctuated wildly from hour to hour, gradually settling down for Sunday night's last opportunity, with K-indices dropping to 1's or Ø's.

With the DST slowly climbing towards positive numbers after a week of coronal hole streaming and auroral absorption, I had hoped that Sunday night's conditions would be a bit better than they were ... although poor, it was the better of the three nights.

Participants in the central and southern states noted excellent conditions and were not as badly affected as listeners to the north, where the effects of any auroral activity are sudden and much more severe ... I'm always surprised at just how much difference one or two hundred miles further to the south can make.

The following NDB's were heard over the course of the weekend, all using the Perseus SDR to record two-minute grabs, every hour, from dusk through dawn. Going over the recordings takes some time but being able to, in effect, listen all night, readilly illustrates how much the band conditions on LF can change so drastically from hour-to-hour ... sometimes for better and sometimes for worse.

It will be nice to see a 'quiet sun' once again, hopefully sooner than later. For such a wimpy solar cycle, this one is not going down without a valiant fight, as it continues to mess-up LF and MF propagation, with an almost non-stop bombardment of coronal hole streams.

In my continuing work with the ham radio AREDN (amateur radio emergency data network) mesh software, I’ve come across the need to provide access from the internet to a host located across the mesh. Unfortunately,  the AREDN graphical interface doesn’t provide a way to do this.

But don’t despair! If you’re capable of editing a file on a linux based platform, you can add your own firewall rules on the AREDN node that is connected to the internet to provide this access. On the AREDN mesh gateway you edit the /etc/firewall file and put in either a routing rule or a SNAT/DNAT rule. The difference is whether or not the gateway node will just pass the traffic through or if it will proxy (NAT) the traffic onto the mesh.

I’m working with the AREDN developers to add this functionality to the gui, and I’d expect that to come out later in 2016. In the meantime, if you’re interested in making this work drop me an email and I’ll send you some instructions! My callsign is KG9DW and I’ve got an arrl.net address.
