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

[Tom McDermott]

I forgot to take notes from the call tonight, likely could not have kept
Someanyway !

Some RF noise generators I could find schematics for on the web are based
on Zener diode noise source
plus amplifier.  Other noise generator components are available, I think
QEX has had articles in the past on this subject.

Here are the links from tonight's Teamspeak session - a whole lot of good
material there.

<18:31:35> "Mike - AA8K": How can we use a reference antenna for
calibration?
<18:33:48> "Mike - AA8K": Is the whip sag an issue?
<18:33:59> "Nathaniel W2NAF": No, the sag should be fine.
