Report Generated: September 27, 2026 at 12:12 PM EST
Period: Next 14 Days
Filter: High-elevation passes (≥70°) any day, any time
About ISS APRS: The International Space Station operates an APRS digipeater on 145.825 MHz
(1200 baud AFSK). This report shows high-elevation passes (≥70°) when you can work the ISS digipeater with
a handheld radio and modest antenna. High-elevation passes provide the best line-of-sight and strongest
signals for successful packet radio contacts. These nearly-overhead passes occur any day and any time.

Equipment Requirements:
- Radio: VHF transceiver capable of 145.825 MHz FM (any HT with 5W will work)
- TNC/Interface: Terminal Node Controller or sound card interface for 1200 baud AFSK
- Software: APRS client (Xastir, YAAC, APRSDroid, etc.)
- Antenna: Simple vertical works well for high passes; better results with directional
- Path: Use ARISS for digipeating through ISS
