otherwise good radio links (ETX 1.0 to 1.2) and found something that may
be of interest. LinkEstimatorP uses an ALPHA parameter of 2 (actually
0.2) for decaying its exponential average of eetx:

This was fixed in December to use an alpha of 9.
Ah, that will probably make quite a difference :)

updates to CTP. In a day or two, there will be a new commit that
