Accept credit cards and sell more at hamfests with free credit card reader

A new electronic payment processing company called Square, named after the shape of their credit card reader that plugs into the audio jack of your smartphone, makes it possible for hams to inexpensively accept credit cards at hamfests. They charge a flat 2.75% of the transaction, but there is no per transaction fee, monthly fee, or equipment to buy or rent.

It’s brilliantly simple.  Download and install the free app for iPhone, iPad or Android. Attach the reader to the audio jack of your phone. Enter the amount of the transaction on the screen, swipe the card, and have them sign on the touchscreen with their finger.  Done.  That’s it.

I think it’s a no-brainer.  Apparently, so does Visa who made a “strategic investment” in the company just last week.

Here is a video demonstration:

Why is this great news for small-time sellers at ham radio swapmeets? Until now, it’s been prohibitively expensive and somewhat complicated for occasional sellers to setup for credit card processing.  Anyone who has tried to price it out knows the drill: statement fees, gateway fees, transaction fees, and on and on.  You simply had to do a certain amount of business each and every month to make even having the capability of accepting credit cards worthwhile.  With Square, there is no transaction fee or monthly charge of any kind.

Without fail, it seems that I always run out of cash just about the time I spot a great deal on a piece of gear. The seller could accept a personal check, but if we’re talking about a pricey item then that’s a pretty risky proposition.  They could use one of those “knuckle buster” card imprinters, but with those there is no real-time authorization and by the time you realize there is a problem a crook could be long gone.  With Square, lack of available funds isn’t an issue.  You’ll know if there is a problem right away.

Some people might balk at paying $13.75 in fees to sell a $500 radio.  Compared to cash, it does cost more.  But, think of it this way: accepting credit cards will give you access to a much wider selection of buyers. You’ll likely get a better price for your radio gear making the fee irrelevant.

Editor’s note:

Some reader comments have expressed concern about chargebacks.  Here is the relevant info from their website:

How Square protects you from disputes

One part of building any payment service is dealing with cardholder disputes. As with everything else at Square, we strive to make dealing with these as simple as possible and we’ll certainly never charge you for it. Read below for a guide on how this works.

  • If one of your customers sees a charge they don’t recognize on their statement, they can call the toll-free number in the payment details that goes straight to us. We have all the information needed to look up the payment and help them get a better idea of what was sold. If we can’t find enough information about the purchase in your account, we’ll reach out to you and ask for more details so we can let your customer know.
  • Sometimes, the customer may go straight to their bank before calling the number and dispute the charge. If that happens, we’ll get a letter from the customer’s bank telling us that this payment is in dispute. We will then contact you to gather more information so we can provide the issuing bank as many details as possible to get it resolved successfully.

Some of the information we can provide in order to resolve disputes are:

  • Customer’s signature
  • Description on what was sold
  • Precise location data
  • Whether the reader was used for the payment or not

Because descriptions help describe purchases to customers, we always recommend our users add a description for the item or service sold as well as issue receipts. Also, make sure that your Account page accurately represents your business name. A customer may not remember the charge if it reads “Joe Smith” instead of “Joe’s Coffee Shop.”

Two biography books for engineers

The F-117 Nighthawk, designed by the Lockheed ‘Skunkworks’. (Image in public domain from Wikimedia Commons)

I have just finished reading ‘Skunkworks’ by Ben Rich and Leo Janos and it should be one of those books that engineers, students of engineering and those that like technology should read. The book details the secret Lockheed Martin aircraft design branch, set up and run by Kelly Johnson, which became known as the ‘Skunkworks’. Out of this special projects group came the F-104 Starfighter, the U-2 spy plane, the SR-71 Blackbird and the F-117 Nighthawk (also called the stealth fighter), amongst other aircraft.  The book starts out with the development of the Nighthawk which was developed by a team led by Ben Rich, who replaced Kelly Johnson as the head of the Skunkworks.  After telling that story of the stealth fighter development over the first few chapters it goes back in time to when Ben Rich first joined the special projects unit and how he became involved in the development of some of the most advanced military aircraft of the 20th Century. The book is an exciting insight in to how advanced engineering projects can be run.  ’Skunkworks’ was allowed to be free from the usual corporate bureaucracy and therefore it could move quickly in development. There was also a philosophy of using off-the-shelf parts as much as possible, including engines, so reducing delays from manufacturing new parts that would then need to be continued to be produced.  Although this philosophy was challenged with the development of the Blackbird which was designed to achieve Mach 3 speeds and so needed to be constructed with large amounts of titanium.

Combining details of how the planes were developed, the challenges and uses of the planes, as well as some insight into management styles and how to obtain multimillion dollar contracts make the book extremely interesting. When you read about the uses of the U-2 in the Cuban Missile Crisis, the shooting down of Gary Powers, and the use of the F-117 in Iraq you can see these aircraft had influencial and important roles in the the Cold War period and beyond. It was also interesting to read about the irony of how a relatively obscure Russian paper on electromagnetic theory  lead a young mathematician at the Skunkworks to propose how they could devise an aircraft that was almost invisible to radar.

Check out your library or bookstore to find a copy of ‘Skunkworks’ and read about engineering at its best.  To illustrate the performance of the U-2 here is a video from the BBC where presenter James May gets a flight in the two seater version of the U-2.  You can see how the U-2 could fly so high it was out of range of fighter jets and missiles (although there is a report of an English Electric Lightning F3 intercepting one at 88,000ft during a NATO excercise in 1984).

Onto the second engineering biography book to read.  This is ‘iWoz’ by Steve Wozniak and Gina Smith, which I read a year or two ago and should have written about sooner.  This is the story of Steve Wozniak, co-founder of Apple and the real technical brains behind the development of the first Apple computers, including the massively successful Apple II.  This is a very personal account, and more like a traditional autobiography than ‘Skunkworks’, but there are some interesting insight into how ‘the Woz’ come come up with the design for computers that effectively started the microcomputer revolution. It is fascinating to read how in high school he collected minicomputer manuals and with the help of catalogues and datasheets of newer components he would redesign the circuitry of those computers to use fewer components. Also interesting is his interest in using components in more than one way on the same board.  Here you can see the real engineering genius coming through. Below is a short clip of Wozniak talking about the ‘economy’ of the design of the Apple II at book signing event for ‘iWoz’.

Summer is not far away so chase down one or both of these books for your Summer vacation.  Lots of engineering inspiration is contained within the both books.

Jan Mayen Island DXpedition

Talk about the trip of a lifetime! This from their new website launched today:

Jan Mayen Island is a volcanic island in the Arctic Ocean and part of the Kingdom of Norway. It is 55 km (34 miles) long (southwest-northeast) and 373 km2 (144 mi2) in area, partly covered by glaciers (an area of 114.2 km2 or 44.1 mi2 around the Beerenberg). It has two parts: larger northeast Nord-Jan and smaller Sør-Jan, linked by an isthmus 2.5 km (1.6 mi) wide. It lies 600 km (about 400 mi) northeast of Iceland, 500 km (about 300 mi) east of central Greenland and 1,000 km (about 600 mi) west of the North Cape, Norway.

Jan Mayen island is not placed at the top of the 100 Most Wanted DXCC list, but it’s still very wanted in some areas and modes – especially West Coast of the USA, Japan, Oceania, Africa.

After a deep analysis of specific areas vs. modes, we decided to focus on CW and RTTY as our primary modes during JX7VPA.

Since our path towards Africa (where, according to feedback we received, it is still very wanted) will be a bit more difficult due to island’s terrain, we will try to test long path conditions if short path fails.

First day of our activity will be used to check openings toward different areas as conditions we will find at the island may be a big surprise due to polar day period 24/7.

The biggest threat we must face while at Jan Mayen is auroral activity. Since the island is in range of often Au oval’s activity, any increase of A/K indexes may result in deep RF blackouts. Please keep that in mind if our signals disappear from bands suddenly.

Take a moment to check out their website and of you’re a CW or RTTY op, mark your calendar for early July.

The 435 Machine

Live audio of the KE6RRI 147.435MHz repeater
Los Angeles, California USA
Contains adult language and adult themes
(Press play button to listen)

I was looking through the online scanner feeds available on RadioReference.com and found a list of the Top 50 Audio Feeds. Most of the large police departments can have quite a few listeners at one time, sometimes approaching a couple hundred listeners.

The single Amateur Radio repeater on the list caught my eye: the KE6RRI 147.435MHz repeater located near Los Angeles. The feed had 120 listeners which is pretty amazing for a ham repeater (for comparison, Chicago Fire Dept. had 40 and Las Vegas PD had 39 at the time). There was obviously something going on here that was attracting attention. So, of course, I tuned in.

Well, it’s quite the experience. Let’s just say that the conversations are colorful.

I remember as a newly licensed teenager that I was super-paranoid about following the rules. I’d stay well clear of the band edges for fear my signal might bleed over due to some malfunction. If the FCC said that I had to identify every ten minutes, I’d make sure to do it every five. Like Christian Slater’s character in the pirate radio movie Pump Up The Volume — I imagined those yellow vans conspicuously marked “F.C.C.” circling the neighborhood just waiting for the most minor of infractions as their signal to move in. Apparently, after spending a little time listening to the 435 repeater online, the folks on this machine don’t seem to worry too much about that.

There are two interesting interview segments worth listening to on The RAIN Report where Hap Holly, KC9RP, interviews Christina Holzschuh, KE6RRI, the current owner of the repeater: Part 1 Part 1 (14 min.) Part 2 Part 2 (14 min.)

SOTA Activation Attempt #2

I attempted to do a SOTA activation today, my second attempt, and I failed again.  Last time I didn’t make any contacts (despite calling CQ on several bands endlessly) and to add insult to injury my cook stove malfunctioned so I couldn’t cook lunch.  This afternoon I went out on a spur of the moment thing and realized when I got to the site that I forgot my battery.  I looked through the Jeep to find something I could MacGyver and only came up with a laptop battery, but I didn’t have a voltmeter along to figure what pins were what.  However all was not lost.  I got to hike up to the site and muck about as they say, go four wheeling with the Jeep through some nearby mudholes, and then take another hike to one of my favorite spots in Pennsylvania.  Perhaps the third SOTA activation try will be a charm.

Trail up to the site

One of the two towers near the site.  This is an old firetower now used by Carbon County, PA.  The cabin at the top was removed.

 

The other tower at the site owned by State of Pennsylvania.  Well built, though a bit bland by radio artisan standards.

A neat spot on a rocky peak about a mile away from the SOTA summit

“Drive-in” antenna hookup? That’s cool!

The Green Valley Amateur Radio Club located in Green Valley, Arizona has one of the coolest antenna setups around.

Located at the site of a former Titan missile base, this 80-foot discone antenna was built by the Collins Radio Company in the early 1960s for the Air Force. Adjacent to the Titan Missile Museum in Sahuarita, Arizona, the discone antenna is enclosed by a barbed wire fence but conveniently has a junction box with a roll of RG8U and attached PL-259, all readily accessible by vehicle.

According to both the museum’s and GVARC’s websites, hams are welcome to use it provided that they check in with the visitor’s center and exercise good manners (roll the coax back up when they’re done). By the way, according to GVARC, the discone has a SWR of 2:1 over the entire 6-30MHz range.

Can you say “plug and play?” If you visit the missile museum while you’re there, please don’t press any of the big red buttons…. Enjoy the video below featuring the museum.
