[TangerineSDR] links from the 6-24-2019 teamspeak session

[John Ackermann. N8UR]

Hi Tom --

Our local VHF/UHF group did a project making noise sources for noise figure measurement.  A couple of the guys, especially Tom Holmes, N8ZM, developed a lot of knowledge along the way.  I'm sure he'd be willing to help out with that part of the design.
