13 Years Later, Still a Bright Idea

In 2003, Les Brown helps guide the replacement beacon on its 233-foot ascent to the top of the AM tower.

Switching to an LED beacon atop KNOM’s AM transmitter tower has saved the mission tens of thousands of dollars in the past 13 years. It’s an example of how we strive to make the best use of our donations.

The Challenges of Staying On-Air

Van Craft with AM Transmitter, Nome, Alaska

When a very rare failure occurred at our AM transmitter in late January, thousands of listeners lost access to our station. It took extraordinary measures — and support from near and far — to get us back on the air. The event also underscored the importance of our efforts to renovate our studios.

  We can’t thank enough the donation of talent, treasure, and time from two incredible KNOM supporters – Tom and Marian Braun – who spent two weeks at our mission last month.

August ’09: “Come back soon!”

August 23, 2009 The transmitter fails this morning, just as the automated remote control commands the increase to daytime power. KNOM general manager Ric Schmidt coaxes it to operate at very low power: about 2,000 watts. The reason for the problem was a lightning strike that severed the jumper cable 100 feet above ground. Due to high…

Time to tighten up

This time of year, we scramble to make sure that we perform routine maintenance on the KNOM buildings and equipment.  As we go through this process, we encounter unusual circumstances. (Several years ago, as we were doing a visual inspection of the AM transmitter site, a herd of muskoxen decided to graze near the tower.) KNOM volunteer…

A DIY solution for an askew building

We’ve been working hard to stretch our financial resources. Sometimes, that means being creative in problem-solving, even when the ground is literally shifting underneath us – as it has, in recent weeks, at our AM transmitter site. KNOM’s AM transmitter building and tower sit on the outskirts of Nome, about 3 miles east of town. From one season to…

June ’87: Fixes at the transmitter site

June 8, 1987 Chief engineer Timothy Cochran and general manager Tom Busch extend the 120 ground wires at the AM transmitter site to 320 feet, 1/4 wavelength at KNOM’s frequency. Because of a shipping error back in 1971, the ground wires had been a hundred feet short for 16 years, but the money is finally in place…
