If you have a Icom Radio like the 7100 or 9700 that has a builded in sound card all you need is a USB Cable and the UISS software package to do APRS from the ISS. The frequency is 145.825 up/down. Mode will be FM-D if you have the Icom Radio. If you have a Kenwood D72 or Kenwood D74, it is builded in aprs. Basically if you don't have a radio that covers two meters with a build in sound card, you will need a interface to connect your radio to your computer. I suggest using the software UISS for sending and receiving aprs messages and data. DE AI4LL On Mon, Mar 31, 2025 at 3:27?PM John Galvin N5TIM via <=[email protected]> wrote:
