Yes. Tis I. Have setup my summer camp 22m FSK CW ("ROM" using QRSS 6) and telemetry-over-WSPR beacons to monitor my site's environment.Telemetry-over-WSPR is a great way to transmit telemetry via HF from remote areas where you don't have internet, cell/Wi-Fi or commercial power but can setup battery/solar power and a simple, resonant vertical antenna. I only need one sensor for the weather telemetry and a simple resistive voltage divider to monitor the solar/battery voltage status. It's a very flexible system and you can use any kind of mathematical bit packing to increase the telemetry payload ala the pico-balloon flights that use a different method of encoding, which I simplified (KISS) for my needs. Albeit I would love to have an anemometer to add wind telemetry, a lux meter and an alarm sensor circuit (normally close).
For those who may be interested, I've attached the decode sheet used by my Excel spreadsheet to automatically decode telemetry that I obtain and import from the awesome WSPR Rocks! website. I use ranges of temperature (TP), humidity (RH), dewpoint (DP), barometric pressure (P in millibars, mB) and solar/battery voltage status (VDC).
