[TenTec] 6N2 observations

[Shawn Upton]

Besides, wouldn't a preamp be best anyhow on 2m and
up, to help with NF and coax loss?  It's another part,
yes; but since no coax is lossless and that also
impacts noise figure, a preamp might as well be used
if you're going to invest money into a good antenna,
good feedline and a good radio.
