April 21 & 22, Fri evening 5:30 to 9 PM, All day Sat 8:30 AM - 6:00 PM
Clatsop Community College, Seaside Campus, Rm 2/3


Licensing exam fee: $14.  

Students will need to provide their own study guide: The ARRL Ham Radio License Manual for Technician, Third Edition. This is available from Amazon in both book and Kindle form. A simple calculator is needed for the test. No cellphone calculator aps are allowed.

This is a Federal Communications License which you must have to operate on Ham Radio Frequencies. Students will learn about radio theory, allowable frequencies, RF exposure limits, repeaters, radio ethics, antennas, as well as other important and necessary subjects to know in order to pass your Ham radio exam. Exam will be given after the class about 4:30 PM on Saturday

The objective of this class is to prepare people to help with radio communications for non-emergency and emergency situations such as wind storms, floods, tsunami’s and other possible man made disasters that may cause major damage, and/or power and communications failures.

April 22, 2017
9:00 am - 4:00 pm

S Columbia Hall Room 219
Clatsop Community College, Astoria Campus


Practice actual live nets, disaster reporting scenarios, traffic handling, and getting more use out of your ham radio.

We will discuss Anderson Power Pole connectors, DC emergency power and some of the problems of battery and solar power. The class will begin by demonstrating the actual programing of a radio using commercially available software. It would be helpful (but not required) if students had one repeater frequency of 145.450 (minus 600) PL 118.8 and a simplex frequency of 146.580 loaded into their radios.

Students are urged to obtain the book "Personal Emergency Communications Staying in Touch Post Disaster: Technology, Gear & Planning" by Andrew Baze.

The day will end with a disaster drill where the students will move out of the classroom to various locations on campus and make simulated emergency reports.

Radio operater

By Jade McDowell | February 17, 2017 | East Oregonian

The biggest natural disaster in the history of the United States, with the power to alter life forever in the Pacific Northwest, will start in Eastern Oregon with the rattling of windows.

That’s what the scientists say.

Rattling windows could mean Cascadia — the “big one” — an 8.0 to 9.0 magnitude subduction zone earthquake that seismologists at Oregon State University predict has about a one in three chance of hitting Oregon and Washington in the next 50 years. Research suggests such a quake has happened an average of every 243 years and the last one was more than 300 years ago.

It could happen 20 years from now. It could happen after we’re all dead. Or it could happen tomorrow.

If it happens tomorrow, the Oregon Office of Emergency Management predicts Umatilla County residents will likely notice some light shaking for four to six minutes, while some Morrow County homes might shake hard enough to knock over unsecured furniture. Next, the lights will probably go out. Then, cell phones, landlines, the internet and natural gas.

Amateur radio

In natural or man-made disasters, ham-radio enthusiasts put their hobby to work.

There’s a sense of urgency in the air at a Virginia nuclear power plant. Everything within at least a five-mile radius is at immediate risk due to a critical meltdown. One of the emergency responders opens the envelope she’s holding, scans its contents, and announces the bad news: “We just lost 911 and the cell towers are overloaded.”

There are some groans, but the team of amateur radio operators knew this was a possibility, and they’re prepared. They have their radios at the ready to coordinate evacuations, making sure that no shelters are overwhelmed and that evacuees arrive at the right locations. Two detach themselves from the rest and make their way over to the lead coordinator. They’re acting as the points of contact for all emergency services, which means they’re responsible for relaying information about everything from fires to urgent medical care to illegal activities.

Mayday 150The Rescue-21 system indicates that the transmitter is South of Cape Disappointment Coast Guard station. However, there is no cross bearing to give them a good location. 

Local amateur radio operators are asked to monitor 156.800 MHz, no PL, 5 KHz wide (not the new VHF Narrow-band used by public safety agencies).  Unfortunately, you will hear routine status announcements & the occasional ship-to-ship transmissions.  What you are listening for is the following voice: https://www.dvidshub.net/audio/45774/rescue-21-recording-false-mayday-call

The suspect is described as a white male adult, 35-40 years old, with an accent indicating he is from SE states or the East coast.  If you hear such a transmission, note your location, the signal strength, & time.

Phone the Coast Guard tip line at 503-338-9021.

Then, phone Don Hillgaertner WA7TEM at 503-338-7428 so he can update Clatsop Emergency Management.  Also keep track of your “monitoring hours”, so they can be submitted as volunteer time.  Any questions can be forwarded to Don at 503-338-7428 or This email address is being protected from spambots.
