In March, 2008, owner Albino Ortega called for help. We answered the call
and made repairs and adjustments to get him back on the air as
quickly as possible.
The KIGO tower stands 326 feet tall, and is located just west of Rigby.

The daytime ATU is fed with 3 inch coax. Having two separate ATUs is mostly
the result of adding nighttime service after the station began operation
with only daytime service.
Jim & Albino inspect the nighttime ATU.
The KIGO transmitter building.
The KIGO main transmitter is a Continental 317C-1, serial number 85.
Through the first window are the solid-state rectifiers. The middle
window gives a view of the PA tubes. The far cabinet houses the
driver section.

We returned to Rigby on April 28, 2008, with specialized test equipment
to find the problem with the nighttime operation. We started with the
night ATU, testing the capacitors, and adjusting the coil taps for an
input impedence of 50+j0 Ohms.
The nighttime transmitter is a Broadcast Electronics AM1. We found a
shorted MOV on the Lightning Protection Board. After making repairs,
we were able to run the transmitter up to a full 1,000 Watts, with
only 5 Watts of reflected power.
