Lecture and Lab 08-25-2018: What to Bring

analyzer setup IMG_20180710_142419262This Saturday’s Lecture and Lab should be a fun one: we’re going to learn about different ways to turn our RTL-SDR USB dongles into antenna analyzers. Bring yourself and your curiosity. Bring $45.00! Bring your RTL-SDR dongle. Bring your favorite ideas about what to do with the RTL-SDR. We’ll have time to talk about them. Besides all those things, you should bring:

    1. A laptop computer. A Raspberry Pi might not have the horsepower, but if you’re stubborn, you can try.
    2. You’ll save time if you download and install the software we’ll be using. We’ll start by doing things the easy way, with the RTLSDR-Scanner. The installation is very easy for Windows, but a little more involved for Mac or Ubuntu. If you have a Windows or Linux laptop, you can also install version 1.2 of Spektrum, which we’ll discuss and experiment with.
    3. Bring your RTL-SDR Dongle! We will not have any for sale. If you’d like to support the club, your could order a dongle or a dongle with small dipoles through smile.amazon.com.
    4. A 12-14V power DC power supply for your noise source. It helps if it has a variety of barrel connectors so that you can be sure of having the right one. It can be very low power; only 0.2 amps are needed.
    5. Bring an antenna to measure. You can even bring more than one. We’re going to have plenty of time to measure antennas, experiment with the scanning software, and share our favorite tips and tricks for the RTL-SDR.

Don’t forget: the DARC needs volunteers for the show-and-tell at our September 4th, 2018, meeting and for our October 27th, 2018 Tech Net on the Hill event. Please sign up! Show and tell presentations only need to be a few minutes long.

Our next Lecture and Lab is coming up in a week: join us on Saturday the 25th to build an antenna analyzer using your RTL-SDR dongle. You’ll need $45.00, a Windows or Linux laptop computer, a 12V power supply, and your dongle. You might also want to bring a VHF or UHF antenna to analyze! I’ll make a special post with more details in the next couple of days.

I’ve also been reminded that the Plano Balloon Festival, Sept. 21-23, is still looking for volunteers. Most of those who’ve signed up already are folks who have to be there: volunteer coordinators, and the like. More hams are definitely needed for this big and beautiful event.

The summer’s heat is still strong, but the end is in sight. That means that the DARC is becoming more active! We’re looking for short, 20-25-minute presentations for our Tech Net on the Hill event this October 27th. Please get in touch with us and volunteer! We also need folks who can share something cool in 5 minutes or less: our next meeting is a show and tell night.

Our next Lecture and Lab will be on Saturday, August 25th. We’ll have a few antenna analyzer kits for $45.00…but even if you don’t get a kit, you can still learn how to use the equipment you order on your own.
