[amsat-bb] FoxTelem with RTL-SDR

[Burns Fisher]

You definitely want the latest release for HuskySat.  1.08z.  I have gotten
a few frames at a time (up to 20) with a jpole and an wide-band amp, but
nothing before this upgrade to z.  And this is with a FunCubeDongle.  No
reports about the RTL-SDR and Husky.  I just know it is fussy to receive.

I'm also not sure about a Pi2.  A Pi3B and 4B certainly works.
