Counterpoise wire experimentation on HT radios with push-connect spade connectors

Several weeks back I wrote an introduction to my first amateur radio transceiver, a handheld Baofeng BF-F8HP.  While researching these radios I kept reading blog posts and reviews indicating that performance is marginal on most stock “rubber duck” aerial antennas.

I decided my first amateur radio experiment should be to try my hand at adding a counterpoise wire to the radio chassis to see if I can quantify any performance gains over the stock antenna.  Rationale for this decision was simplicity—I already had all the tools and supplies needed down in my basement from other projects.

No reason to feel intimidated taking your first amateur radio license exam

It was five minutes to noon and cold rain fell hard against a troop of girl scouts as they ran with poster-board projects from the door of the Hopewell Branch public library to their parents’ idling cars.

I’ll wait five more minutes, I thought as I sat dry in my own car watching through the rear-view mirror.  The exam doesn’t begin until twelve-fifteenMaybe I’ll catch a break in the rain.

I spent two months preparing for my Technician exam and set my eyes to attend the closest license session, a twenty-minute drive from my home that was sponsored by the Delaware Valley Radio Association (DVRA).  By the time exam day arrived I had taken several online practice tests and passed most with a comfortable margin, missing only two or three questions on each attempt.  I’ve got this, I thought.

How to remove news article suggestions from the Google Chrome browser on phones and tablets

In October 2017 I wrote about escaping the news and my difficulties with social media apps.  To continue with this theme, I discovered a method to remove news article suggestions from the Google Chrome browser on my Android Nexus 5x phone and Nexus 7 tablet.

Disable server-side suggestions to remove news article suggestions from the Google Chrome browser on phones and tablets

The left-pane of the three-panel image shows the Google Chrome browser displaying news article suggestions by default.  To disable this:

  • Enter chrome://flags in the browser search bar

The middle-pane of the image shows various browser settings in this well-hidden menu.

  • Scroll down to the setting labeled Show server-side suggestions on the New Tab page and select Disable in the dropdown box.  Press the Relaunch Now button that appears at the bottom to save the settings

The right-pane of the image displays new, blank Google Chrome tabs without any news article suggestions.

 

 

 

Three study resources for the Level 1 Technician Ham Radio License exam

Five days from now I will visit my local library and sit for the Level 1 Technician Ham Radio License exam.  I feel confident I will pass the exam largely from the help I received by three study resources below.

Depending on your age and prior knowledge of Ham radio operation, you may believe that knowledge of Morse code is required as part of the examination process.  This is no longer true as of 2003.  Knowledge of Morse code is no longer a requirement to achieve a Ham radio license!

The ARRL Ham Radio License Manual

I began my adventure studying for the Level 1 Technician Ham Radio license exam by reading through The ARRL Ham Radio License Manual only once.  I admit I felt intimidated when I reached chapter two, but I pushed ahead regardless of thoroughly understanding some of the context and lessons.  I purchased the Amazon Kindle electronic version for $19.95 as opposed to the $29.95 soft cover.  I experienced some formatting issues with the two-column practice questions and answers, but it isn’t a large enough roadblock to purchase the softcover book if you’re already comfortable with e-readers.

The Ham Whisperer on YouTube

After reading The ARRL Ham Radio License Manual I discovered The Ham Whisperer on YouTube, specifically Andy’s Technician License (Updated and good through June 2018!) playlist.  The format of the video series is excellent as Andy walks through the question pool, culminating each lesson with a brief quiz of the actual exam questions.  I really like that each lesson is structured in approximately ten minute sessions.  More can be found on Andy’s website here:  hamwhisperer.com.

HamStudy.org

Simultaneously while working my way through The Ham Whisperer playlist I would take a random practice exam from HAMSTUDY: Technician Class (2014-2018).  I took two practice exams per day over the period of two and a half weeks.  My first six exams I failed miserably but slowly started to watch my scores climb into the 80% up to an average now of 96%.  The point here is repetition as actual exam questions and answers are presented.  The exams are structured well and include the correct answer and a brief explanation upon conclusion of each exam.

Shrink a hard disk partition before upgrading to a smaller capacity solid state drive

Do you remember any notable events from the year 2011?  Pop culture websites tell me it was the year the band R.E.M. disbanded after thirty-one years, comedian Russell Brand and singer Katy Perry filed for divorce, and actor Charlie Sheen was fired from the hit television show Two and a Half Men.

I don’t recall significant personal life events attributed to 2011, but records show me in July of that year I bought a Dell XPS 17″ laptop to replace a two-year old Dell netbook that was a tad too small for everyday use.  I still use this laptop six and a half years later.

Why Microsoft Excel’s new AutoSave feature may cause you to lose work

If you’re a user of Microsoft Excel 2016 at work or home then you may have noticed in the past few weeks the new AutoSave feature that appeared in the top menu bar.

Escaping the news and my difficulties with social media apps

I’ve had enough.  I took a bold step last night and wiped several apps, mostly social media, from my mobile phone and tablet.  I am on a quest.  I must escape…the news.

A partial list of social media applications available in the Google Play store

I watch little network broadcast television at home but it feels like I am subjected to a barrage of news headlines where I least expect them.  Simply opening the Google Chrome browser on my Android phone reveals a miniature headline and thumbnail graphic by CNN:  Las Vegas gunman planned to escape after massacre, sheriff says.

Thanks, but what does that have to do with my need to purchase a replacement utensil basket for my dishwasher?

There must be a way to disable news headlines from the Google Chrome application on my smartphone.  I can’t find a setting so unfortunately I’ll have to search the web for a workaround.  Oh shucks, it’s a vicious cycle.

Taken a few great photos? Consider licensing them for use by writers under Creative Commons

As a writer for the web I like to embed a featured photograph with each article I share online.  This practice is not uncommon and you may agree it adds an elegant accent to written content when opened in news reader applications on desktop computers and mobile devices.

Unfortunately it’s difficult for a single author to take a relevant photograph for each potential article.  An organization named Creative Commons strives to broaden accessibility of media content like artwork, music, photographs, and videos for use within other forms of print and online media.

My first amateur radio transceiver: BaoFeng BF-F8HP

I discussed a few days ago How a box fan sparked my interest in amateur radio.  If like me you’re just getting started with the hobby then you’ve already discovered the passionate discussions online about when to buy a radio and the qualities that make for a good first tranceiver.

Not sure what I mean?  Have you ever been in the company of one guy (or gal) who drives a 5.0-liter Ford Mustang and a second guy (or gal) who drives a 5.7-liter Chevy Camaro?  Yes, it’s a lot like that.
