OCRA Membership Meeting – March 11, 2019

Introductions:

Treasurer Report:

Dan (KR4UB)

We have 68 paid membership current and 33 requiring renewal.   You can renew membership easily and securely on the website under the heading of “Members.”   

Chatham county continues moving forward with establishing new radio towers.  Currently they are writing specifications to publicly bid the work.  They plan to establish additional towers beyond current need for anticipated growth, with the understanding it is more cost-effective to erect the additional towers now than re-bid the work at a future date.  

WordPress is the most common blog and website platform in use around the globe.  OCRA uses WordPress as our primary club communication channel.  WordPress has many additional features and functionality that we can leverage for multiple uses.  One such use is capturing interest and availability for Field Day. 

With just under four months to go, Field Day 2019 is quickly approaching.  However, we can more easily start planning now.  Dan has created an on-line sign-up form to capture availability to volunteer for food, station, and field site preparation, staffing, and dismantling.

You can easily complete the sign up form on your computer or even phone!  The steps for expressing your interest and availability follow:

 1.     On the site, navigate to the “Member” tab and click “Receive Access Link”.

 

2.      Enter your call sign, answer the math question, and click “Submit”.  An email will be sent to your registered public email address.

3.       You will receive a confirmation screen notifying you the link has been sent to your email.

4.     Login to your registered email address and click the link.  If you bookmark this link, it can be used to update your profile…be sure to bookmark!

5.     Complete the Field Day sign-up sheet.  Be sure to click the “Save” button located at the end of the form.  If there are any data corrections, they will be highlighted in red.  Band captains will reach out to you regarding the specifics. We look forward to seeing you during Field Day!

Program:  Connectors

As many Hams know, it is important when making decisions about getting the right coax for your Ham Station to understand that there are trade-offs that have to be considered between transmitter power, antenna gain, coax loss, and your total Ham Station system performance.  Your bank account may also enter into the equation like most Hams.

Cables and connectors are no exception to the above as they make up the lifeline of your entire station, allowing all of the components to work together.  Steve (KZ1X) shared that oxygen is the enemy of every connector, as oxidation due to poor connections will limit the performance and life of the connector.   Dan (KR4UB) and Steve (KZ1X) further explain the importance of having the right connectors, wires, and crimpers to produce a gas tight crimp.  As Dan shared, in his experience most poor transmissions are the result of bad connectors.  However, with quality material and practice you can build connectors that provide decades worth of radio fun and enjoyment.

Chatham County Radio Club Update, Nick (KA1HPM):

Chatham County radio club has established a club station at the county emergency operation center (EOC) with two VHF and two HR radios, and Winlink.   The club as applied for a vanity call, but with the FCC currently on furlough, it may be some time before the call is issued.

The club is preparing for an April 30 communication exercise at the Shearon Harris nuclear power plant.  Rehearsal for the event will be March 28. Please join the club net every Tuesday night on 442.15 MHz, PL tone 131.8. Hope to hear you on the air!

Vice President: Lad (W4ORD) – The Holiday Meal was well received.  However, suggestions to explore new food options are being considered.

“When All Else Fails:”

With the recent weather events in Wilmington, NC, hospitals are encouraging employees to become amateur radio operators offering communications when “all else fails.”  Opportunities for local radio clubs to assist may be forth coming.

NC QSO Party:

The NC QSO Party is quickly approaching.  This year, the event will occur on Saturday, February 24 from 10:00 AM to 8:00 PM EST.  This is a great event to sharpen your SSB skills with running or search and pounce.  Click on link above for more information.

Club Meetings:

If you are new to amateur radio, or would like to refresh your knowledge, the Program Committee would like your ideas.  Considerations are being given for having instructions on coax termination with soldiering or crimpers.  Or, how to build an affordable wire dipole.  Do you have any suggestions on program content?  If so, leave a reply below.

Club Program:

Pete (WA1YYN) provided an overview of several emergency and life saving devices.  First, Pete created a GPRS enabled apparatus comprised of a raspberry pi that can be attached to a fire fighter’s outfit that captures both health and situation metrics. For example, the apparatus can capture, record, and transmit fire fighters body temperature, pulse oximetry, acceleration, etc.  such data is vital for ensuring situational safety.

Pete also explained that many emergency response communication technologies are proprietary and expensive.  He mentioned that the national fire protection association (NFPA) and NIST, national institute of standards and technology are working together to develop emergency response data interoperability and deployment standards.

Pete (WA1YYN) discussing his use of GPRS and amateur radio in emergency response communication and coordination.

 

 

 

 

 

Pete demonstrated an open source solution providing GPRS tracking with real time monitoring and visual overlay perspectives of the rescuer, drone, and incident command.  This solution will more accuracy and quickly identify persons in need improving resource coordination thus reducing response time in saving lives.

Pete’s work in supporting emergency response fulfills several key goals of amateur radio:

  • Supports the awareness and growth of Amateur Radio worldwide;
  • Advocates for meaningful access to radio spectrum;
  • Strives for every member to get involved, get active, and get on the air;
  • Encourages radio experimentation and, through its members, advances radio technology and education; and
  • Organizes and trains volunteers to serve their communities by providing public service and emergency communications.

What is your passion?  What aspects of amateur radio keeps you involved?  Let us know by leaving a response below.

OCRA Membership Meeting, August 13, 2018

Introductions:

Treasurer Report:  Dan (KR4UB)

Club balance was reported.

Dan created a new attendance sheet.  He also went through old club records to capture the date members joined.  There are many current members who helped establish the club in the early 1990s, when the club was called the Orange County Wireless Pioneers.  Steve Jackson (KZ1X) was the spark plug for establishing the club.  The first meeting was in the community room of OWASA.  Anyone with club records, please let Dan know. Dan will scan and add the content to the site, which will help preserve club records.

Dan has a repeater still occupying space in his basement.  The current repeater market in Durham and Alamance is rather saturated.  However, as Chatham County is growing, so is the need for communication towers.  Nick (KA1HPM) mentioned that the county is planning to install several new towers for 2020.   There may be opportunities to relocate the repeater to a tower in Chatham County for amateur radio and CERT usage.

Field Day results:

While radio propagation was sketchy, we were able to accumulate 2000 more points this year over last.  Every station, minus 80 meters, was able to increase their score, with digital exceeding last year by over 1000 points.   This year’s numbers will change slightly as Dave (W4SAR) thoroughly combs the combined log to eliminate duplicate contacts, fix broken exchanges, and eliminate broken exchanges that cannot be made good:

For more detailed information on Field Day, we encourage you to read the July 2018 DFMA newsletter. https://www.dfma.org/TheLink/2018/Link1807web.pdf

Show and Tell

Steve (KZ1X) was cleaning out an old radio box and brought in a Micron SWR field strength meter, which may have been purchased as the old Radio Shack in University Mall.  The Micron measures the amount of signal transmitted by your antenna system, and a signal pattern can be plotted by taking readings around your antenna.  The meter covers 3 to 30 MHz and can handle up to 1KW.

He also brought alligator clips with magnifier glass used for splicing wire and adding connectors.

Dave (KW4XL) brought in several 3D printed products, including a raspberry pi hotspot case and working crescent wrench.

The next membership meeting is scheduled for Monday, September 10.  Hope to see you there!
