I can only speak for Yaesu and Icom gear
Has anyone tried taking the K3s 2nd IF out to a high end soundcard and doing
the DSP on a PC?

I don't think there are any soundcards capable of handling the 8+ MHz IF
output from the K3, but LP-PAN converts that IF signal down to baseband
and does exactly what you are asking about with PowerSDR.

The 2nd IF is 15kHz which is well within the capabilities of many sound
cards. But it would require surgery to the K3 as this signal is not
available externally. It would certainly be an interesting experiment for
the bold risk taker. Most PC SDR software needs an I/Q pair of signals which

No, typical transmitted bandwidth for communications use -
including FM is about 100 Hz to 3000 Hz.

I can only speak for Yaesu and Icom gear, but Yaesu
rigs specify 5Khz transmit FM in their manuals and in
the Icom 706MKIIG service manual states FM deviation
is adjusted for 4.5Khz

Hi there,
I am running my K3 with Digipan computer software on PSK 31.
I also have a full complement of 5 filters in the K3, with
the widest
LP Pan and WinRad are using the K3's IF, not the audio output from the K3.

I didn't see that requirement in the original post's question: Does someone
know how to receive USB at a 13Khz bandwidth with the K3?
Actually, I tried it and it seems that PowerSDR is limited to
The K3 audio channel is designed for communications audio in a bandwidth
of 5 kHz or less. There are a number of reasons for this.
Using the 13 kHz roofing filter doesn't change that. It does widen the
IF passband and make the radio more susceptible to nearby, very strong
signals. Think of
