KGNU’s FM signal has a power of about 4 Kilowatts, an increase over our previous strength, but lower than other commercial FM stations. Reception might be improved you are haven’t been able to hear KGNU clearly on 88.5 FM in the past. 

An indoor or outdoor FM antenna attached to the receiver may improve reception.


During daylight hours, KGNU’s AM signal covers the greater Denver Metro area.

At sunset, to avoid interference to other radio stations at the same frequency in other areas, AM signal power is reduced per FCC requirement.

An antenna oriented towards Englewood, CO may improve AM reception.
