mt63-wasm

This WASM module wraps work done by Pawel Jalocha, SP9VRC and Dave Freese, W1HKJ on the MT63 transmitter and receiver in C++ for Linux.

The original code for this repo is by Richard Bateman, founder of HamStudy.org.

Notes

The resulting code for this module is inlined inside the generated .js file. As the module is not large (the resulting file is about 94kB), we see this as a sufficient workaround to importing the module across environments without resulting to other hacks before new URL(url, import.meta.url) is universally supported.
