WaveShark

144-148 / 430-450 MHz

Amateur VHF and UHF

APRS packet, SSTV pictures, M17 digital voice and the repeaters that identify themselves in Morse.

The amateur bands carry several modes at once, and that is exactly what this receiver is for: APRS on the calling frequency, SSTV on 144.500, M17 on the digital voice segment and FM repeaters in between, all decoded from one span rather than one at a time.

A KISS TNC on --kiss-listen hands the packet traffic to the software you already run, and keys AX.25 back through a radio that transmits.

What lives here

  • APRSPacket stations, digipeaters, weather stations and vehicle trackers, with a KISS TNC so your own software can use the same radio.
  • M17The open digital voice mode, decoded in full: callsigns, packet messages and Codec 2 speech, with nothing patent encumbered in the way.
  • SSTVPictures drawn line by line as they arrive, in Martin 1 and 2, Scottie 1, 2 and DX, and Robot 36 and 72, saved to disc when the transmission ends.

Every band, one receiver.

The decoders do not follow the dial: everything inside the span runs all the time.
