BIG NEWS!

We're Officially a 501(c)(3) Non-Profit!

Hat's off to EC Dave Purdle and DEC Mike Slupinski for this incredible achievement! This status allows us to maintain momentum, properly serve the community, and offer you the support you need in the community around you.

What's Happening Now

Weekly ARPSC Net

Join us every Thursday at 7:00 PM on the WA8MAC repeater (147.200 MHz, PL 100.0) for our weekly net. This is a great opportunity to practice your radio skills, stay connected with fellow operators, and stay informed about ARPSC activities.

Note: We do not hold a net on the 3rd Thursday of each month when we have our in-person meeting instead.
Monthly In-Person Meeting

Last In-Person Meeting: Tape Measure Yagi Antennas

What is a Tape Measure Yagi?

A tape measure Yagi antenna is a lightweight, portable directional antenna made from common steel tape measures. It's a popular DIY project in the amateur radio community because it's inexpensive, easy to build, and highly effective for directional signal work. While these antennas are typically built for VHF frequencies (2 meters / 144 MHz), we built UHF versions (70 cm / 440 MHz) as a hands-on training experience!

The antenna consists of three elements made from tape measure material:

  • Reflector – The longest element, positioned behind the driven element
  • Driven Element – Connected to your radio, this is where the signal is fed
  • Director – The shortest element, positioned in front to focus the signal

The flexible tape measure material allows the antenna to be folded up for transport and springs back into shape when deployed—perfect for portable operations!

Radio Direction Finding (RDF)

Radio Direction Finding (RDF), also known as "fox hunting" or "T-hunting," is a technique used to locate the source of a radio transmission. The tape measure Yagi is ideal for RDF because:

  • Directional pattern – The antenna receives strongest signals from the front, allowing you to "point" toward the transmitter
  • Portable & lightweight – Easy to carry while walking or driving to track a signal
  • Null detection – The sharp side nulls help pinpoint direction more accurately

RDF skills are valuable for emergency communications—locating downed aircraft ELTs, finding interference sources, or tracking lost persons with radio beacons. It's also a fun competitive activity at hamfests!

Why Learn RDF?
  • Locate sources of interference on repeaters
  • Find emergency locator transmitters (ELTs)
  • Participate in "fox hunt" competitions
  • Assist search and rescue operations
  • Develop practical radio skills

Go-Kits Are Being Deployed!

ARPSC has started deploying Go-Kits to members for testing and emergency readiness training. These portable kits will permit us to operate with our own infrastructure throughout the county using our own self-deployable resources.

You might see us setting up at a local park one day for practice—be sure to come by and say hi!

We Need YOU!

We are actively looking for new members. As we grow, we need the manpower to provide the impact we aim for.
