K3 Computer Interface

Thanks Bill,

I have an LP-PAN coming.

Assuming LP_Bridge comes along to allow PowerDSR to
control K3 - is there some great benefit over HRD?

Any benefit?

I have used PowerSDR a small amount with softrock and
then switched over to Rocky.

Also, I just read my QST last night, it has a review
on Flex 5000.

Read the ending paragraphs "is Flex for you?"

It indicates that association with the PC is mandatory
from the start and if you enjoy such things,
Flex could be your Nirvana.

K3 allows me to have a base radio, and then address
the computer association later,
if I want, and to the extent of my interest. It's also
instant on.

I consider these pluses, Ymmv, etc... ;-)

HRD is primarily rig control and PowerSDR is a DSP
program for SDRs.  WU2X
wrote a version of PowerSDR-IF that will operate on
the K3's IF via LP-PAN.
However it requires HRD for rig control, so you
actually run both
simultaneously.  Eventually N8LP will publish
LP-Bridge which will allow
PowerSDR to directly control the K3.

For background on the LP-PAN:

To run any of the SDR programs (PowerSDR, CW Skimmer,
Winrad) on the K3, you
need the following:

KXV3 > LP-PAN > Sound Card > Computer > DSP software.

The specifics of the sound card and computer required
vary depending on the
speed and resolution needed.

Hi Don. Yes, there are advantages to LP-Bridge. The most important one
is that it acts as a server for the K3. It allows multiple programs to
talk to the K3 at the same time. Any program which can talk to a K3 can
transparently do so through LP-Bridge using an easy to set up virtual
com port. This means any logger, CW Skimmer, PSK programs, etc... all
while providing a high speed computer interface to PowerSDR at the same
time. Communication is bidirectional and simultaneous from all connected
programs (up to 3 in the initial release).

LP-Bridge will also provide more interface channels to PowerSDR, much
faster software mute, better integration with the K3 for filter offsets,
etc. I will be releasing the LP-Bridge beta as soon as Scott, WU2X is
ready to release the next PowerSDR - IF Stage version. He is close to
doing that, and has a working copy of LP-Bridge for testing.

The version I showed at Dayton was actually mimicking HRD to be able to
control PowerSDR, but that is not a viable version to release as it
prevents the use of HRD. Scott's new version will have a HRD / LP-Bridge
choice in setup.

Your last paragraph is exactly why I bought a K3 and developed LP-PAN
and LP-Bridge. I want it all... a high performance radio I can touch and
feel, but all the computer bells and whistles as well. I guess I'm just
another spoiled Baby-Boomer ;-)

For more info, email me directly or post queries to the LP-PAN reflector
