Amateur radio operator and RF aficionado in Manhattan's unforgiving, high-noise-floor, concrete-and-steel RF-hostile operating environment. Interested in SDR (RTL-SDR, Uniden SDS200, Malahit DSP1). I occasionally write ham radio software (my Python program for texting with the REYAX RYLR998 is available at https://github.com/flengyel/RYLR998-LoRa). I work for The City University of New York. Part-time hikikomori.

I just acquired a pair of 915MHz Meshtastic Messengers ("Meshengers," available from Etsy) and watched them form a mesh with a Meshtastic Mesh Device Station Edition G1, which I'll connect to a flat panel circularly polarized 8dB gain antenna--this works with up to 15 W input. The FCC allows unlicensed operation in the 33cm ISM band up to 160mw (22 dBm)--hams can operate on a secondary basis. To run the Station G1 at 3W I must disable encryption, which is quickly done with the Meshtastic app.

#introduction Ham operator and radio aficionado interested in SDR (RTL-SDR, Uniden SDS200, Malahit DSP1), 33cm band chirp spread spectrum, and ham radio software development (my python program for texting with the REYAX RYLR998 is available at https://github.com/flengyel/RYLR998-LoRa). Slouching toward POTA operations, following OH8STN. I work for The City University of New York. I was briefly active on 40m as a nervous CW operator and on 2m and 70cm NFM until the building management discovered my antennas.
