[Boatanchors] Collins R 390 and an R 391 sets

[Ray, W2EC]

Major difference is that the R-391 is an "autotune" version (actually
auto-channel selection) of the R-390, uses motors to select the
frequency. Extra controls on the panel for hands off channel selection.
Take a look at my web page and you can find a video of my R-391 in
action. "http://www.w2ec.com/W2EC.html"
