[Elecraft] "Contester's Spectral Display" feature of N1MM software will be supported soon

[Richard Ferch]

No, you don't have to purchase Win4k3, but with a K3 or KX2 you will need
some additional hardware.

I have been using the N1MM+ spectrum display for several weeks with my K3.
The software interface I use is N2IC's Waterfall Bandmap program (<
https://groups.yahoo.com/neo/groups/waterfallbandmap/info>).

You do need external hardware with a K3 or K3S, regardless of which
software you use. I have used Waterfall Bandmap and the N1MM+ spectrum
display with three different hardware configurations: an SDR (SDRPlay RSP1
or RSP2) fed from the K3's RX ant in/out connections; the same SDR fed from
the K3's IF Out; and an LP-PAN plus dedicated sound card, fed from the K3's
IF Out. All of these require the KXV3 to be installed in the K3 (it's
already built in to the K3S).

My understanding is that Win4k3 supports the same configurations and adds
the P3/P3SVGA to the list of hardware it supports. Waterfall Bandmap does
not support the P3/P3SVGA.

Win4k3 also supports the KX3 without external hardware other than a sound
card, and the KX2 or KX3 with an SDRPlay plus an external transmit/receive
switch. I believe Waterfall Bandmap should support these two configurations
as well, but I don't know whether either of them has been tested.

Win4k3 also has many other features, and it may well be worth the purchase
price to you for those features alone - but it is not mandatory in order to
use the spectrum display in N1MM+.
