## Harmful interference
+
+
Part 97 requires you not to cause harmful interference and to take steps to resolve it when you do.
+
Two stations both operating legally on a shared band must work it out between themselves — no one
+
"owns" a frequency, including net and repeater users, although band plans and long-established nets
+
carry real moral weight.
+
+
## Dealing with deliberate interference
+
+
1. **Do not respond.** Acknowledgement is the reward the jammer is seeking, and it is the single
+
most effective thing you control.
+
2. Keep operating normally. Log the times, frequencies and content.
+
3. Record it if you can, along with directional bearings if you have a beam or a direction-finding
+
setup.
+
4. Report persistent cases through the ARRL Volunteer Monitor program and, for serious cases, to
+
the FCC Enforcement Bureau.
+
+
## Direction finding
+
+
Coordinated "fox hunts" are a club sport and a genuinely useful skill; groups that hunt for fun on
+
Saturdays are the ones who locate a real interference source in an afternoon.
+
+
## Interference to and from consumer equipment
+
+
See [RFI and noise](/wiki/station/rfi-and-noise). Most complaints from neighbors involve poor
+
immunity in their equipment rather than a fault in your station, but courtesy and a box of ferrites
+
resolve far more cases than citing the rules ever has.
