[aprssig] HF noise measuring campaign reports via APRS

[Lynn W. Deffenbaugh (Mr)]

I agree that the standard APRS telemetry is definitely the preferable 
approach, but since your example packet (below) showed 8 floating point 
values of apparently some level of precision, I didn't suggest a format 
that only supports 5 values ranging from 0 to 255 (per spec, but some 
say 0..999) that can be scaled based on defined parametric equation 
coefficients.
