I've been in process of building and testing a dual-band 2m/70cm antenna for several weeks now. Recently, my antenna fell and it came time to rework it. A friend of mine was kind enough to loan me an MFJ-269. During the tweaking process, it's convenient to be able to just keep track of SWR values over the bands as well as a place for notes and changes to be marked for each test. Maybe you'll find it useful.

One of the things that we take for granted given our connected society is radio. It is strange how something invisible has had such a visible impact on our world and our culture. For the past 100+ years, radios have been conceived, built, improved, and now exist in everything from satellites to home security system window probes. They carry entertainment as well as troops orders. At any given moment, hundreds of communications from all around us are likely passing, unbeknownst, right through us.

I've reverted to using 16GB SD Cards to move sundry items between an ASUS Laptop and a MacBook Pro. While not the speediest method, it is the fastest considering that:

A couple of years ago, I wrote some custom functions to help speed up working on estimates for our clients. Well, those functions have been lost since I left Classy Llama, but I think the these versions are much improved anyway.
Anyway, here are some Google Apps Script functions for Spreadsheets which might be useful for those in Technical Sales or software development. They can be used to add up and manipulate hour ranges (e.g. SUMRANGE(["1-2",2,"2-5"]) would yield "5-9"). Those functions are SUMRANGE, SUMRANGEHIGH, SUMRANGELOW, RANGEMULT, and RANGEADD.

Doing some research while building some stuff for our store and I stumbled upon a couple of different things you can do to "enhance" QR codes.
You can overlay an image on your QR code directly. To make this work can take a bit of trial and error, but to make this work, build your QR code with the maximum amount of ECC (error correcting code). Then, just slap an image down over the QR code and you are good to go. Like this:

I was unboxing my 1st Gen Drobo today so that I could plug it into my Airport Extreme to share it on my network. I got a blinking amber light. So I plugged the Drobo into my Mac and I get this message in Console...

I saw this hint on how to get a list of the WiFi networks you have associated with. I'm one of those guys that uses Keychain Access to grab old passwords. This is way easier. I'm not sure what versions of OS X this will work on. Mountain Lion for sure, but probably 10.6 and up.
Just add this to your .bash_profile:

Well, it has been 24 hours since I last looked Facebook. I turned off notifications on my phone and went a step further on my laptop. I have this bad habit of creating a new tab and then tapping F-A- and letting autocomplete finish the job.

In my previous post, I mentioned that my wife had gotten me a Kindle
Fire for Christmas and that I read nearly every day on it. It is no
surprise to me that this morning, while going through my News Reader, I
happened upon this article over at Coding
He discusses the pros and cons of both printed and eBooks and summarizes
his thoughts thusly:
