The best frequency to listen to ham radio on your scanner depends on your interests and location, as amateur radio operates across various bands. Here are some general guidelines:

1. VHF and UHF Bands:
   - 2 Meter Band (144-148 MHz): This is one of the most popular bands for local communication. Look for frequencies around 146.520 MHz for simplex communication.
   - 70 Centimeter Band (420-450 MHz): Another active band, with many repeaters. Check around 446.000 MHz for simplex.
2. HF Bands:
   - For long-distance communication, consider the HF bands (3-30 MHz). Popular frequencies include:

• • 20 Meter Band (14.000-14.350 MHz): Active during the day and good for long-distance contacts.
  • 40 Meter Band (7.000-7.300 MHz): Often active in the evening and good for regional contacts.

1. Repeater Frequencies:
   - Many regions have local repeaters that can be found online through repeater directories. These are usually listed with their input and output frequencies.
2. Special Events and Nets:
   - Check for local nets or special event frequencies that might be active in your area.

To get the most relevant frequencies, consider joining local ham radio clubs or online forums where enthusiasts share active frequencies and tips for listening.
