Winlink and RMS Express EMCOMM Capabilities

Presented by Bill Hickey, AB7AA

What Digital Modes Does Winlink Use?
What is RMS Express?
Together, What Can They Do For EMCOMM?

Winlink is a global hybrid network that employs both radio and internet for digital communications. It was initially developed by ocean sailors to support email communications worldwide, but it has undergone extensive refinement over the past 8 years to enhance it explicitly for EMCOMM. RMS Express is the user level software written to leverage the Winlink network for EMCOMM. RMS Express can employ digital modes such as Pactor and Packet which have hardware TNC’s, as well as Packet, Winmor, and ARDOP which have software/soundcard TNC’s. RMS Express can also communicate via TCP/IP, which makes it a candidate for communicating over the Internet, MESH, D-STAR, or cell phone SMS networks. The presentation will cover an overview of the network and basic RMS Express email messages with attachments at the new users level, but then continue to highlight recently developed features of interest to experienced users.

Bill was first licensed in 1965 and has held his present call (AB7AA) since upgrading to Amateur Extra in 1993. He spent his college years as a broadcast and studio recording engineer in commercial AM/FM/TV stations while receiving an undergraduate degree in Mathematics with Physics minor, and then did graduate studies in Systems Engineering. After college he spent a career flying various fighter aircraft while developing, evaluating, and teaching electronic warfare systems and tactics. He achieved the position of squadron commander in the Air National Guard A-7D Fighter Weapons School and helped initiate the F-16A Fighter Weapons School. After retiring, he had a second career as a commercial airline pilot.

All About MESH Networks

Presented by Mike Boger K7BUM

AREDN Final Logo 0So what is a Mesh Network and what can you do with it? How does it help us in our communications and our emergency planning?

Well, a Mesh Network includes things like Nodes, Firmware and of course antennas. Like other networks, Mesh Networks include routers. Mike will discuss Linksys vs. Ubiquiti vs. Netgear.  He will also point out the differences between Broadband Hamnet and AREDN and will also show you the existing Pima County / Southern Arizona Mesh Network. Several clubs are participating in building out the Mesh Network locally including RST. ARCA is also involved in the project. Perhaps OVARC might join in.

Mike Boger, K7BUM, is a Tucson native and is the Deputy Home Stations Manager for the Pima County Office of Emergency Management Communication Group. He is an IT Specialist for 25 years with Texas Instruments specializing in enterprise storage and data protection. He is a U.S. Army Signal Corps Veteran (Multichannel Communications) and also a veteran of the Arizona Air National Guard (Weapons Control Systems, A7D/K).

February 2016 Club Meeting - "Radios, Antennas, Grounds and Chokes"

Handy tips on setting up and optimizing an HF station

Presented by George Cooley NG7A

Antenna and transceiver specs can be confusing. Ask any two hams how much gain your antenna needs and you might get 10 opinions on dBi, dBd, how many radials, not to mention a discussion on whether they should be buried or raised! George will offer tips on setting up a shack with the best bang for the buck for your budget and yard. A review of antenna basics, using chokes to reduce neighborhood noise, and how to avoid RF in the shack will be presented.
