[Elecraft] K3 Win4k3Suite Question

[Tom]

Hi,
Your options are as follows:
First you need the IF output from your K3.  Win4K3 does not support an RX 
antenna solution on the K3.  However, you can use another spectrum display 
product like HDSDR or SDRUno synced with OmniRig to Win4K3.  You would have 
to be sure that your SDR device is switched out and grounded during 
transmit.

Assuming you have the IF out, only the LPPAN and the SDRPlay devices are 
supported in Win4K3.  There is no support for EXT_IO drivers.
Since you already have a sound card for use with your KX3 I would suggest 
the LPPAN unit.

Please feel free to join the group  https://groups.io/g/win4k3suite.
The group is just starting up.

As an alternative, you will need an IF to I/Q conversion device
(SoftRock, LP-Pan, etc.) and a sound card capable of 96KHz sample
rate (preferably 24 bit).

The SDR (e.g., the basic SDRPlay RSP) is probably less expensive than
the I/Q demodulator/high end sound card option these days but if one
already has a suitable sound card, the demodulator might work.
