SARC 2018 Field Day…

Hi Scottsdale Amateur Radio Club Field Day participants,

In the past couple of days we have received a little rain but it’s unlikely there was enough rain for the Forest Service to open the closed areas before Field Day occurs next weekend.  Our first alternate site outside the closed areas (just SE of Kendrick Peak) is still open for camping (NO OPEN FLAMES).

Here is the club field day location as listed on the ARRL field day locator website (  It’s labeled as Water Haul Tank or Aspen Tank on Google Earth on Fire Road 245 just west of Highway 180.


The weather should be cool and comfortable.  Be sure to bring your camping supplies, water and food.  Due to fire restrictions, we might not be able to heat up food unless we have an electric hot plate. So plan appropriately for your meals.

I hope to see many of you at Field Day.

Field Day 2018

Field Day Sticker (2018)ARRL Field Day is the single most popular on-the-air event held annually in the US and Canada. On the fourth weekend of June of each year, more than
35,000 radio amateurs gather with their clubs, groups or simply with friends to operate from remote locations.

Field Day is a picnic, a campout, practice for emergencies, an informal contest and, most of all, FUN!

It is a time where many aspects of Amateur Radio come together to highlight our many roles. While some will treat it as a contest, other groups use the opportunity to practice their emergency response capabilities. It is an excellent opportunity to demonstrate Amateur Radio to the organizations that Amateur Radio might serve in an emergency, as well as the general public. For many clubs, ARRL Field Day is one of the highlights of their annual calendar.

  1. What is the channel spacing? Does this buy us anything?

Scottsdale ARC AREDN Mesh Network Information

What is a Mesh Network?

A mesh network is basically a wireless computer network. Computers connect to the mesh network via access points referred to as nodes. Think of a node like a transceiver which works in the 2.4GHz, 3.0 GHz or 5.8GHz microwave bands you connect a computer or mobile device to.   Now, the software or application on a computer connected to a node can send and receive data through the mesh network to anothercomputer or device connected to the mesh network.

A Mesh network is a highway over which data travels. Turning on two mesh nodes creates a data network. This “highway” allows data
