Hi Folks,
I have a Z1 buffer board in my K2 and have used it to drive a
softrock as a panadapter for some time. It works just fine, but I have
left this uncalibrated and my PC doesn't really have enough horsepower
to run my external soundcard.
I have been trying to reduce PC overhead and
fully supports K2, with extensive support for offsets
for all modes.

1. 4898 KHz is the nearest to 4915 KHz cheap, off-the-shelf crystal that
Tony (developer of Softrock) found. It has the advantage for anyone not
using a high isolation buffer amp such as the Z1B, that the local
oscillator leakage is outside the K2's crystal filter bandpass. This
Hello fellow SDR enthusiasts,
I have looked around a little bit and haven't found a very definitive answer
for the questions that I'm having about the way the K3 and external SDR
equipment works.
I've been looking into the LP-Pan which converts the IF output from the K3
into (im guessing)

Hi Geoffrey,
Perhaps the ARRL Handbook, Chapter 15 - DSP and Software Radio
Design, might help? Section 15.6, in particular describes the math
behind calculating the in-phase (I) and quadrature (Q) portions of a
wave form.
As for specific device compatibility with particular software
packages,
Oh thank you. I Have the handbook but didn't know there was a DSP section. I'll
take a look at that.

If you're interested in DSP code you might try using quisk instead of
PowerSDR.
It's written in mostly Python and a little bit of C, and works on Linux and
Windows.
I made some modules for it to talk to the K3 rigcontrol, but those aren't
necessary to use it with the LP-PAN output, just for the

I wonder what the sensitivity of the P3 is in this regard; I can't see it

The answer is it depends. :=)
The tentative spec for the noise figure of the P3 itself is 10 dB,
although it typically is a couple dB better than that. If you do the
math, the noise figure of the K3/P3 system is within a dB or so of the
NF of the K3 alone.
But how does that translate to what

Does anyone have the correct settings for the K3 to work properly with the

to the IF and switch output the levels seem very low, I can see signals on

Steve in the SDR-IQ Spectraview videos on you-tube the averaging was set to 1
which is much to fast as it shows all noise and signals in real time.
Changing the averaging setting to 5 or 10 will average out all peaks and give
you a very good presentation of signals.

I used CW keyeing via serial successfuly. Now after splitting the port via
Eterlogic to connect SDR-IQ, it does not work.
Did anybody get it to work?
Would LP-Bridge work?
Would it cause timing problems?

Just checked one of the largest online computer parts retailers,
newegg.com, and they've still got the E-MU 0202 selling for $99.99, same
price I paid for it 6 months ago so I wouldn't expect other online
retailers to be higher or lower than that by more than $5.
So, $225 + $100 = $325 or $175
