Amateur (ham) radio is a medium by which people can communicate on specific frequency ranges designated by the FCC for personal, hobby, educational / training, or emergency purposes. While the Ratzlaff family uses ham radio for some or all these purposes at various times, our primary use of ham radio is for emergency communications in the interest of family preparedness and their associated training. We have five licensed ham radio operators in our family at DN40dh (ITU Region 2, CQ Zone 3, ITU Zone 6, Call Sign Area 7, DXCC Entity 291, GPS 40.297161, -111.6950295):

Noji Ratzlaff (KNØJI)

Lisa Ratzlaff (KR5LYS)

Ricky Ratzlaff (KDØWRV)

Katie Ratzlaff (KI7NQD)

Eric Ratzlaff (KG7EKY)
