How About a New 12 Volt Automotive Connector?
Don’t get me wrong — I do like standard connectors. A while back, I wrote about how the micro-USB connector became the standard power/data connector for mobile phones. Well, that is unless you own an iPhone.
The good news is that we do have a standard power connector for 12 VDC in automobiles. The bad news is that it is an ugly behemoth derived from — can you believe it? — a cigarette lighter. For some background and history, see the Wikipedia article. The Society of Automotive Engineers (SAE) has a standard that describes this power connector (SAE J563). Alan K0BG correctly warns us to “never, ever use existing vehicle wiring to power any amateur radio gear” including the 12 volt accessory plug. (I always follow this advice, except in the cases when I don’t.) I also found this piece by Bill W8LV on eham.net that describes the crappiness of these connectors.
Well, there is a new standard power connector showing up in cars: the USB port. These ports provide the data and power interface for mobile phones, integrating them into the auto’s audio system. Standard USB ports (USB 1.x or 2.0) have a 5V output that can deliver up to 0.5A, resulting in 2.5W of power. A USB Charging Port can source up to 1.5A at 5V, for 7.5 W of power. This is not that great for powering even low power (QRP) ham radio equipment.
Now a new standard, USB Power Delivery, is being developed that will source up to 100W of power. The plan is for the interface to negotiate a higher voltage output (up to 20V) with 5A of current. Wow, now that is some serious power. We will have to see if this standard is broadly adopted.
Two things are obvious to me: 1) the old cigarette lighter connector needs to go away and 2) it is not clear what the replacement will be.
What do you think? Any ideas for the next generation of 12V automotive connector?

Twisted Phonetic Alphabet
Stu W0STU just posted an article on HamRadioSchool.com about the use of phonetic alphabets. I had previously posted a Shack Talk article on the same subject.
The “standard” phonetic alphabet is the ITU alphabet but I am starting to think that we might need to get a little more creative on our use of phonetics. Why not innovate in this area, just like we innovate on the technical front?
Towards that end, I was reminded of his phonetic alphabet listed over at netfunny.com:
A Are N Nine B Bee O Owe C Cite P Pseudonym D Double-U Q Queue E Eye R Rap F Five S Sea G Genre T Tsunami H Hoe U Understand? I I V Vie J Junta W Why K Knot X Xylophone L Lye Y You M Me Z Zero
Even this creative alphabet can be improved on. For example, I think H should be Honor.
What do you think?

SOTA Activation: Kaufman Ridge HP (W0C/SP-081)
It was a nice fall day, so Joyce K0JJW and I decided to go for an easy hike up Kaufman Ridge HP (W0C/SP-081) and do some SOTA operating. Well, maybe the hike was her idea and the Summits On The Air thing was my contribution to the plan. The hike is less than a mile and has about 900 feet in elevation gain, depending on where you start the hike.
This definitely a slacker operation: easy access, easy hike, great weather and 2m FM activation via a handheld radio and the 1/2-wave whip.
Note that there are two SOTA peaks with the “Kaufman Ridge” name: Kaufman Ridge North (W0C/SP-085) and Kaufman Ridge HP (W0C/SP-081), located near Trout Creek Pass in Colorado. Today we headed to SP-081 which we reached by following County Road 318 from Trout Creek Pass, which is also called Buckrake Drive and then Windmill Drive. These roads pass through private property to reach the San Isabel National Forest, where there is a gate that closed from December to April (see map). At this point, the road is easy 4WD, most 2WD high clearance vehicles will do fine. You can also approach from the south on FS 308 through Mushroom Gulch. 
We turned left onto FS 308 and then took a short side road FS 308B toward the summit. There are several over turn offs but 308B seems the best (shown in black on map). The road is blocked for vehicular traffic at 38.858659° N / 105.933921°W. You can continue walking on the road a ways or just head straight for the summit. While the hike is short and not that steep, there are plenty of downed logs to give you a challenge.
You never know who is going to show up on 146.52 MHz in the mountains but I had put the word out via email to some of the local hams to let them know I was doing a SOTA activation. When I got to the summit, I had a few stations already calling me and I quickly worked Ron N0MQJ, Fred N0VXE, Dave K0HTX, Jim KD0MRC, Bob W0BV and Don K0DRJ. Don was my “best DX”, about 60 miles away in Woodland Park with a few mountains in the way. Thanks to everyone that came on frequency and contacted me.
Side note: if you want to activate SP-085, go north on a forest service road (not shown on map) near where 318 and 308 intersect. Just drive a short ways north, find a parking spot and bushwack your way up the summit. You could easily activate both summits in one day.

The Completely Updated Incomplete List of Ham Radio iPhone Apps
It is about time I updated one of my more popular posts about my favorite ham radio apps on the iPhone and IPad. As usual, I will focus on free or low cost (less than $5) apps that I am actively using. Some apps have just disappeared from iTunes and new ones have emerged. While this list is completely updated, it is still incomplete, because there are so many apps to choose from.
From the Simple Utility Category:
Ham I Am (Author: Storke Brothers, Cost: Free) A handy app that covers some basic amateur radio reference material (Phonetic alphabet, Q Signals, Ham Jargon, Morse Code, RST System, etc.) Although I find the name to be silly, I like the app!
Maidenhead Converter (Author: Donald Hays, Cost: Free) Handy app that displays your grid locator, uses maps and does lat/lon to grid locator conversions.
HamClock (Author: Ben Sinclair, Cost: $0.99) A simple app that displays UTC time and local time. This one reads out to the second.
There are quite a few good apps for looking up amateur radio callsigns:
CallBook (Author: Dog Park Software, Cost: $1.99) Simple ham radio callbook lookup with map display.
Call Sign Lookup (Author: Technivations, Cost: $0.99) Another simple ham radio callsign lookup with map display.
There are a few repeater directory apps out there and my favorite is:
RepeaterBook (Author: ZBM2 Software, Cost: Free) This app is tied to the RepeaterBook.com web site, works well and is usually up to date.
For a mobile logbook (and other tools):
HamLog (Author: Pignology, Cost: $0.99) This app is much more than a logbook because it has a bunch of handy tools including UTC Clock, Callsign Lookup, Prefix list, Band Plans, Grid Calculator, Solar Data, SOTA Watch, Q Signals and much more.
To track propagation reports, both HF and VHF:
WaveGuide (Author: Rockwell Schrock, Cost: $2.99) This is an excellent tool for determining HF and VHF propagation conditions at the touch of a finger.
If you are an EchoLink user, then you’ll want this app:
EchoLink (Author: Synergenics, Cost: Free) The EchoLink app for the iPhone.
There are quite a few APRS apps out there. I tend to use this one because my needs are pretty simple….just track me, baby!
Ham Tracker (Author: Kram, Cost: $2.99) APRS app, works well, uses external maps such as Google and aprs.fi. “Share” feature allows you to send an SMS or email with your location information.
Satellite tracking is another useful app for a smartphone:
Space Station Lite (Author: Craig Vosburgh, Cost: Free) A free satellite tracking app for just the International Space Station. It has annoying ads but its free.
ProSat Satellite Tracker (Author: Craig Vosburgh, Cost: $9.99) This app is by the same author as ISS Lite, but is the full-featured “pro” version. Although it is a pricey compared to other apps, I recommend it.
For Summits On The Air (SOTA) activity, there are a few apps:
Pocket SOTA (Author: Pignology, Cost: $0.99) A good app for finding SOTA summits, checking spots and accessing other information.
SOTA Goat (Author: Rockwell Schrock, Cost: $4.99) This is a great app for SOTA activity. It works better when offline than Pocket SOTA (which often happens when you are activating a summit).
For ham radio license training, I like the HamRadioSchool.com apps. (OK, I am biased here as I contribute to that web site.)
HamRadioSchool Technician (Author: Peak Programming, Cost: $2.99) There are a lot of Technician practice exams out there but this is the best one, especially if you use the HamRadioSchool.com license book.
HamRadioSchool General (Author: Peak Programming, Cost: $2.99) This is the General class practice exam, especially good for use with the HamRadioSchool.com book.
Morse Code is always a fun area for software apps:
Morse-It (Author: Francis Bonnin, Cost: $0.99) This app decodes and sends Morse audio. There are fancier apps out there but this one does a lot for $1.
Well, that’s my list. Any other suggestions?

Three Steps to Getting Your Ham Radio License
These are the three basic steps to getting your USA amateur (ham) radio license: 1) Learn the Material 2) Take Practice Exams and 3) Pass the Real Exam.
This article is very short and to the point, for a more detailed explanation see Stu’s article over at HamRadioSchool.com.
1. Learn The Material
The entry level ham radio license is the Technician License, so you’ll need to get a book that covers the theory, regulations and operating procedures required by the Federal Communications Commission (FCC). My recommendation is the Technician License Course over at HamRadioSchool.com, which offers an integrated learning system (web, book and smartphone app).
While you can learn the material on your own, many people find classroom instruction to be very helpful. Check the ARRL web site for courses in your area or just do an internet search for “ham radio license class” and your location.
2. Take Practice Exams
The question pool for the Technician Level Exam is made public, so you have access to every possible question that will be on the exam. Better yet, various organizations have created online practice exams so you can test yourself in advance. After you study the material, take these practice exams to test your knowledge. Go back and study any topics you are having trouble with on the exam. A passing grade is 74%, so you’ll want to be consistently above that before trying the real exam.
These are a few of the available online practice exams: qrz.com, eham.net and aa9pw.
3. Pass the Real Exam
The FCC exams are administered by radio hams known as Volunteer Examiners (VEs), so the exam session is sometimes called a VE session. In most areas, there are exam sessions given on a regular basis. Check the ARRL web site to find a license exam session in your area.
Be sure to follow the instructions of the local VE team, since policies and procedures do vary. If you’ve studied the material and checked your knowledge by taking the practice exams, you should have no problem passing the Technician level exam.
4. One More Thing
Actually, there is one more step to this process. Getting the required FCC license is just the start, a learners permit for amateur radio. You’ll need to get on the air and gain some practical experience. It is extremely helpful to have some help during this process, so I highly recommend that you connect up with a local ham radio club. If you can’t find a club then perhaps make contact with a local ham or two.
There are many hams out there that are willing to help. However, it may be a challenge to find one. You can always drop me an email and I will try to assist.

This Spewed Out of the Internet #29
More important information insight stuff spewing forth from the interwebz:
The actor Tim Allen, who’s character on the TV show Last Man Standing is a ham radio operator, recently received his Technician License. According to Wikipedia, Allen holds the callsign KK6OTD under the name Tim Dick.
The FCC says that Marriott has been interfering with their customers’ use of WiFi hotspots at the Gaylord Opryland Hotel and Convention Center in Nashville, Tennessee. It seems that they wanted to “encourage” customers to pay for WiFi service.
ICOM has made available some cool amateur radio guides on their web site, including a World Map, USA Band Plan Chart and a USA VHF Grid Map. Oh, ICOM, please note that those grid locators are not actually “squares.”
Those Ham Hijinks guys must have bought a new ribbon for their typewriter since they’ve cranked our these articles: Obama Signs Ham Radio Executive Order and Man Creates Multi-Purpose Rotator.
Over at HamRadioSchool.com, I added another Shack Talk article, this one about ham radio awards: Operating Awards: Chasing Wallpaper.
