+# ASMR
+ASMR: Automatic S-Meter Reader
+
+This program reads location from a GPS dongle and the S-Meter from a
+transceiver via a serial port and stores the results in a CSV file
+so you can run analysis in another program.
+
+Inspired by RFI Mapper (RFIM) by [W4DD](https://www.qrz.com/db/W4DD) 
+and written in Rust.
+
+# Use Cases
+- Drive a route and measure variation in noise level, to determine local noise sources
+- Record noise level at a fixed location over time, to determine temporal noise patterns
+- Some combination of the two
