K3 and SDR Integration

[Bill W4ZV]

         W0YK's comment about missing the Pro3 bandscope
reminded me of this.  I hope someone (K8ZOA, HB9DRV,
N4PY or ?) will look into integrating SDR software (Rocky,
PowerSDR, etc) with the K3 and Softrock hardware on the
K3's 8.215 MHz IF output.  What I would love to see is:

1.  A bandscope display (good sensitivity and resolution).
2.  The ability to place a cursor on a signal of interest.
3.  Clicking the cursor moves the K3 VFO to that frequency.
4.  Perhaps add a waterfall display for weak signal work.

I believe most of the bits and pieces to do this exist now,
but it needs to be integrated into a seamless package.
Someone might have a nice product opportunity to do this
for those who may prefer operating to fussing with computers.

                                 73,  Bill  W4ZV

I personally think that going the SDR route is overkill - and requires a ton
of code. But - having had a bandscope on my IC-7800 (now sold) I would
dearly like a bandscope. I do hope that Wayne and Eric and their friends
will investigate and design this once the dust settles later this year.

I honestly don't want to get inside the SDR code - I just don't have the
time. At one stage I was planning to do this but I'm having to spend
significant time on my commercial activities.

An Elecraft or Elecraft-approved bandscope with a serial or USB interface
would be my preference so that I can integrate it with my software.

I like the projects on http://www.cliftonlaboratories.com/ .

Sounds like something one could do with a cheap pc-based oscilloscope,
such as the bitscope http://www.bitscope.com/ (cheap considering that they
promise 100MHz analog bandwidth and 40MS/s sampling).
You can get them with RS232, USB, or ethernet interface. The software
interface docs are available on the website and they even give you an
interface library for windows and linux :-)
