[Elecraft] 2nd RX

[Guy Olinger K2AV]

In a contest, one can work something called SO2V, where off a run frequency,
you scan the band away from your run frequency, or move it to a new spot and
pick it off while maintaining your run frequency.  Not easy to do (the
distraction and mental breakdown quotient is very high for this kind of
stuff), but extremely handy if you can get your brain to do it.

You can put the other RX on another antenna and listen to other bands at the
same time, including AM broadcast or HF broadcast. I do that a lot during
the summer listening to Yankees baseball games.  I will often just leave the
second RX on the other frequency.  Why use this quality of RX for that
purpose?  I can listen to them using SSB on a RX antenna and use fast AGC on
a pretty bad signal that would be intolerable listening AM. I set the
frequency to 880.000 kHz and the audio is perfect, no trace of Donald Duck.
It even renders music acceptably though not quite perfectly.  When noisy I
narrow the bandwidth for best balance of "intelligible sound" and
signal-to-noise.

I use DDR for 160 and 80.  The improvement in RX is immense and allows me to
pull out very poor signals.  The spread of noise in the headphones allows me
to effectively ignore the noise.

Setting the TX in the clear with working someone split is invaluable.  I
often run up the bandwidth on the second RX (listening to the split
frequency) to 2.7 kHz just to hear the range and detect the DX's pattern on
RX.

There was something else but cannot recall at the moment...
