Cat Pix on the Air CPOTA 2026

/

Cat Pix on the Air (CPOTA) 2026 will celebrate International Cat Day by transmitting images of cats via SSTV.

The internet was made for sharing funny cat pictures and movies. On August 8th, International cat day, so will the radio waves! Ham radio amateurs will celebrate this day with a special SSTV event using cat pictures only.

This contest will score the number of QSOs made by each operator. Special callsigns PD6MEOW (Netherlands) and N1C (US) are already registered. Additional special callsigns may be registered with the event.

RaDAR Portable Ops Challenge

/

RaDAR (Rapid Deployment Amateur Radio) is a portable operating challenge focused on a simple cycle: move, deploy, and make contacts. Held on the first Saturday of April and November, the challenge provides a four-hour window to test your ham radio skills and gear through multiple deploy, operate, and move cycles.

How it Works

The goal is to make five contacts (QSOs) at each location before moving the required distance to your next stop:

  • On foot: 1 kilometer

  • By bicycle: 2 kilometers

  • By motorized vehicle: 6 kilometers

Scoring

  • RaDAR to RaDAR: 3 points

  • POTA or SOTA: 2 points

  • Other contacts: 1 point

  • Final Score: (Total QSO points × Number of stops) + Bonus points

Rules

You may use any band or mode (HF, VHF, UHF, voice, CW, or digital), but repeaters are not permitted to ensure a focus on field-style, point-to-point operating.

The RaDAR concept was created by Eddie Leighton (ZS6BNE), and the RaDAR Rally is coordinated by Greg Lane (N4KGL). Registration is now open for the upcoming event.
