The people who keep us on the air

KNOM AM transmitter

KNOM’s AM transmitter site in winter.

Last week, we welcomed the last of this year’s five volunteers to Nome. Lucus Keppel is from Michigan and has committed one year to the KNOM Radio Mission. He joins Margaret, Eva, Dayneé, and Josh. They look forward to a wonderful year of service to listeners in remote bush communities.

As always, we thank everyone who helps us overcome each obstacle and meet every challenge. Sometimes, our challenges are of a technical nature.

Recently, KNOM’s AM transmitter shut down, and the sensor monitoring the temperature inside our transmitter building read 128 degrees! The fans had turned off and had failed to restart. After cooling the building, engineering volunteer Rolland Trowbridge located the reset switch in a control panel and restarted the AM transmitter, returning the KNOM signal to the air.

In the rare moments our AM signal goes offline, we often receive phone calls from listeners asking us “where did you go?” We’re gratified to have such devoted listeners – and dedicated volunteers, staff, and community members who make sure such outages are not just rare, but also brief.
