Bahamas – sailing and ham radio
16 March 2016 | by My wife and I have an upcoming trip the Bahamas. We’ll be meeting our friends Keith and Terri on their live-aboard sailboat. I got a wild thought…I should take the KX3 and end-fed half wave antenna along, and I’ll be maritime mobile from the Exumas! I submitted the paperwork via email, and anxiously awaited my callsign. I got a response back really quick from Ms. Linda with the Bahamian government, asking for an additional form to be completed. My credit card was quickly charged the $35 fee. Today I checked with Ms. Linda on the status. I found out that I won’t receive my license until AFTER I return from my trip. This is all on me, as I should have planned this out sooner.
There’s still a chance that my license will arrive in time, but it’s a pretty slim chance. Fingers crossed.

Carrington Probabilities
K7RA's 'Solar Update' in this week's ARRL News, mentions Jeff Foust's recent article in 'The Space Review', reminding us again of the dangers posed by a modern-day 'Carrington Event', also known as the 'Solar Storm of 1859'. A large solar flare in late August, hurled a monster-sized CME towards earth, making the 93 million mile journey in just 17.6 hours compared with the more normal rate of several days.
Huge auroras soon lit up the sky as far as central Mexico, Hawaii and the Caribbean. The aurora was so bright, it was reported that Rocky Mountain goldminers awoke in the middle of the night, and thinking morning had arrived, started to prepare breakfast. Telegraph lines and equipment burst into flame while some circuits continued to be usable with power supplies completely disconnected. The 1859 event still remains the most geoeffective solar storm since records have been kept.
Such an event today, of course, would wreak much more havoc ... probably having devastating consequences for decades and causing trillions of dollars of damage.
From Foust's article:
Was that, though, just a fluke event? .... Pete Riley, senior research scientist at Predictive Science Inc., offered a probabilistic forecast for the likelihood of another Carrington-like event, based on that storm’s estimated strength and measurements of the actual strength of solar storms over the last few decades. “If you the (sic) time between events, you can calculate the probability of the next event occurring within some unit of time,” he explained.
His estimate of the probability of another Carrington event is surprisingly high: about a 10 percent chance of such an event occurring over the next decade. “Ten percent is very, very high,” said William Murtaugh, assistant director for space weather at the White House’s Office of Science and Technology Policy (OSTP) ... “A one-percent probability over the course of the next one hundred years of a storm with an impact of that magnitude is considered very, very high and will motivate action.”
Interestingly, for this prediction, the actual strength of the solar storm of 1859 can only be estimated. If it was actually twice as strong as thought, then the probabilities drop from a (decade) 10% probability to just a 1% chance.
The U.S. government has recently set up a NASA multi-million budget funding proposal to study the likely effects of future large scale impacts and possible “response and resiliency capabilities” but it's not known if these will carry over to any new administration.
“Fortunately in space weather there’s no real politics,” Murtaugh said. “Both sides of House, both sides of the Senate, Republicans and Democrats, are both keen to work together to do something about this issue.”
The article has brought some interesting 'food for thought' comments, among them:
I think it is excellent that there are steps being taken to improve our understanding of the probabilities and predictive accuracy of such solar events, but I'm concerned that it isn't entirely clear how that information will translate into major investments in civil engineering that will make us less vulnerable to them. As for asteroidal impact threats, it's one thing to have a observations and research that will provide predictive information, and another to prevent tragedy. In both cases, it's about how we'll actually prevent such destructive effects once predicted. Prevention is a LOT more expensive than prediction, and is thereby ripe for threat denialism, which seems to be an emotion that has thoroughly infected at least the leaders of our nation.
It's a little funny about how much energy is being spent advocating human spaceflight for colonization and settlement as a means to save the species, but so little is being devoted to specific threats to the species, and to individuals in particular. I could get killed in an asteroidal impact or a severe geomagnetic storm, but sending a shipload of people to Mars sure isn't going to protect me.
I am a member of Infragard, which is dedicated to supporting efforts to protect us from risks to our electrical grid and other critical infrastructure. A novel "One Second After" by William R. Forstchen accurately illustrates the effects of a similar intentional attack on our grid and how it creates a cascading collapse of our society. Gas stations cannot pump gas, food rots in the stores, more food cannot be delivered to all the needed locations, and the people who know how to fix things cannot reach where they are needed and also starve to death. The result of a severe Carrington event with no effective preparation or protection for the giant transformers could thus cause most of our population to starve in a few months. This risk is about 1% to 0.5 % per year and is like having everyone playing Russian roulette once a year with 200 pistols where just one is loaded.
A modern day 'Carrington repeat' does indeed give pause for thought but perhaps the generally predicted upcoming 'grand solar minimum' will buy scientists some extra time to come up with solutions for what will eventually occur ... and, one more thing's for certain ... it'll be a heck of an aurora!

Weather forecast is looking good
The weather is looking good for Saturday for my planned expedition to Morristown National Historical Park (NPOTA HP28) this coming Saturday. Sunny with high temperatures in the upper 40s (9C) Hopefully, there will be no curve balls out of Left field that will preclude me from going.
The plan is to leave the house somewhere around 11:00 AM (1500 UTC) and be up there and on the air by around 12:00 Noon (1600 UTC). I plan on working 40, 20 and 17 Meters - CW around the QRP watering holes. I'll be packing some water and snacks and hope to stay for three or four hours. I am going to see if I can get the PAR END FEDZ 40/20/10 up in a tree in the parking lot. If not, I'll just rely on the Buddistick for 20 and 17 Meters and a Hamstick for 40 Meters.
Last Saturday, I went to the Cherryville hamfest out in Flemington, NJ which is run by the W2CRA, Cherryville Repeater Association. This was the very first hamfest that I ever went to as a newbie Ham back in 1979, and it's always held a special place for me. Unfortunately, over the years (and especially since the dawn of eBay) the Cherryville hamfest seemed to be on the down slope. Like a lot of hamfests, it suffered from poor attendance, lack of vendors, etc was plaguing it - and seemed to be spiraling towards its death knell.
Happily, between last year and this year, that trend seems to be reversed. Attendance is still nowhere near where it used to be, but it's growing. The number of vendors is still down (but again, growing), and for the most part the really bad junk is gone - and by junk I mean non-ham related garbage. I mean really, who wants to buy a roto-tiller at a hamfest? Sure there's still lots of non-Ham stuff to be seen, but it also seems there are more and more treasures to be found.
I purchased some new SO-239 chassis connectors as well as two old butterfly type variable capacitors that I got for five bucks. The capacitors have long stems on them, so they should be useful in my magnetic loop antenna project. I need to clean them up with some contact cleaner, but some initial testing seems to indicate that they are in the 200 pF range. KJI Electronics was there, and I purchased a Diamond antenna for my VHF/UHF handheld. What a difference when you buy the real brand and not a cheap knock-off!
Before I forget ........ I have a friend who has a "hardly used, very good condition" SGC-2020 QRP radio that he wants to sell. I am not privy to the price. But if you're interested, send an e-mail to [email protected] and I will forward it on to him. He's not looking for eBay type money, but he's not interested in getting taken, either.

Portable Ops 4/45: A SKCC Kind of Day!
I have been a member of SKCC for some time now, but never really done anything with it except hand out my number if asked- I’m 8033 if you’re interested.
Anyway, this weekend while I was playing radio from the shack, I worked a few guys in the SKCC Weekend Sprintathon – 5 to be exact. This lit some type of fire inside me to work more of these guys!
If you are a new CW operator, these Op’s are great to work. They take it nice and slow typically matching your speed, and tend to be good operators that you can learn from.
So anyway, I decided to really start putting some effort into working more SKCC operators – it seems like in the past I have almost always heard some QSO’s around their calling frequencies. The first award I will work towards is the Centurion – which requires you to work 100 SKCC members.
So before today I had worked 5 members from the weekend.
Today I listened around 14.050 from the local park. I heard a few stations, but decided to call CQ.
AA7XP – Herb answered my call and gave me a 329 he was a 459 here. His number is 14525T.
Then I called CQ again and…
KE6OIO answered from CA with a 599 signal, she gave me a 559. We had several nice exchanges, her SKCC number is 1204T.
So that puts me at 7/100 for SKCC members worked – still a long way to go, but I am going to enjoy the ride.
I do need to get a better straight key! Right now I have just set my KX3 paddles to work as a hand key. I just push on one of the paddles to form the dits and the dahs – but I need something better! I might have to fire up my sons 3D printer and print something off!
