|Mike Kingery, KE4AZN has written a telemetry decoder, TlmEcho, that will allow the user to view and capture telemetry that is downlinked by Echo in real time. Echo's telemetry is sent in the broadcast stream via the Satellite's digital downlink (PacSat protocol). TlmEcho also stores received data for offline viewing and submission to Echo's Telemetry Archive. TlmEcho runs on Windows only and requires that you also download and install both the Coefficients File (echocoef.csv) and the TlmEcho User Files.

Decoding Echo TLM requires you have at least a 9600 baud TNC. Emily Clarke W0EEC has compiled a list of TNCs with operating notes based on information provided by AMSAT members.
Program Notes: The program is designed to run on screen resolutions of 1024x768 or greater, but will run on an 800x600 screen with minor limitations.
