K3S 15KHz output?

[Bob Novas]

Far as I can tell, there is no 15KHz output from the K3S that can be used
for experimenting with SDR. Is that correct? Thanks, Bob W3DK

Bob,

No 15 kHz output, but better for SDR experimenting, use the IF output at
8.215 MHz.  That gives you a output that is prior to any IF filters in
the K3S.
If you want baseband I/Q outputs, you can connect a softrock receiver or
LPpan2 to that IF output.

Bob,

The K3 and K3S have an internal 15-kHz (nominal) 2nd IF that goes to the DSP. But this is not a quadrature signal like in the KX3, and it also follows the crystal filter, so it is very narrow band.

Not to hijack this thread, but has anyone used the IF out of a K3(s) w/
a Funcube Dongle Pro+?

Yes, I've tested it a long time ago.
It worked OK. Think I used SDR#.
