[Elecraft] Sub-rx or P3?

[Craig D. Smith]

I've obtained both relatively recently, and my vote would be for the P3.

The P3 is quite useful for seeing the calling freq of stations in DX
pileups, so in that regard it satisfies one of the functions of the sub-RX.


Unless you really need to use diversity or to monitor the audio on another
frequency or band, the sub RX has limited additional utility.  It is pricy
($700 to $1000+ depending on your choice of filters) and adds considerably
to the internal complexity of the K3, making service access more difficult.
But it does work well and increases the flexibility of the K3.

The P3 is eye-opening.  At a glance you can see everything happening on the
band segment of your choice without touching a tuning dial.  I've found lots
of DX with it already before it appeared on the clusters.  The display is
excellent - very clear and sharp.  The functionality of the P3 will get even
better as the expected hardware and firmware upgrades become available.
