use with LP-PAN is available from several sources. Most is free.
Use the following
steps to order LP-PAN 2.
ordering, it is
recommended that you read the Installation
Guide, and for kit builders, the Assembly Manual.
A working knowledge of computers is very desirable. Most users have
had no unusual problems setting up the software, but PowerSDR can be a
little tricky on some systems, especially for overseas users. It is recommended that you install and
all the software before even ordering LP-PAN. Just use an audio source
such as the output of the K3. The display will only show the center
3kHz of spectrum, and there will be no image rejection, but everything
should work properly otherwise. It
is especially recommended if you are in another country to check the
software in advance to make sure that it works with your country's
regional settings in Windows.
Installing the latest drivers for your
chosen sound card and your OS is
essential to smooth operation. Studying the Sound
Card page is recommended, as well
as the Setup & Configuration page for your selected sound card.
Reading the mail on the LP-PAN
User Group can also be quite
useful. With hundreds
of LP-PAN systems in the field, there are plenty of users who can help
if you run into problems.

Sound Card Info
Please read before
deciding on a sound card.
Buffer Mod Simple mod that improves noise floor of panadapter
display by reducing loss in the K3 IF output. Not required, but some
users have found it well worth the effort. The link takes you the Files
section of the LP-PAN User Group. Elecraft now offers a mod kit very
similar to this, and has incorportated the mod into current production
buffer kit from Clifton Laboratories (Jack, K8ZOA) to add an IF
to the K2 and Orion.
K2 Mods: You will find detailed K2
in the Z10000
Orion Mods: Rick VE7TK has posted this
paper on Orion
and N4PY software also support
Orion and LP-PAN. Rick also has this paper on configuring
N4PY software with PowerSDR/IF v1.19.35. K2 will
be fully supported in LP-Bridge soon, but
currently can be controlled using HRD. Roberto, EB4EQA, has published a similar paper
with some interesting differences here.
board for FT-950/2000, manufactured by RF Space,
is available from HRO. This is
required to use LP-PAN with these
radios. This board is a third party product, and was originally
designed for use with RF Space's panadapter product. It is
successfully being used by a number of LP-PAN users with excellent
results. We are looking into creating a more cost effective version of
the board, if demand is sufficient.

notice about SDR software: The LP-PAN IF decoder hardware works
with almost any SDR software program... WinRad, Rocky,
CW-Skimmer and various custom versions of the open source PowerSDRTM
program from FlexRadio Systems. The user can use any or all of the
above programs, many of which are freeware or open source. We recommend several programs which
are more tightly integrated with LP-Bridge.
Freeware from N8LP. LP-Bridge is the "glue" that ties everything
together... rig, SDR app,
loggers, RTTY apps, web clusters, CW Skimmer, etc. All the apps get
access to the rig at the same time with a very simple to use interface.
The original LP-Bridge is designed to work with the K3 and supports
PowerSDR/IF, TRX-Pan and NaP3. LP-Bridge 2 (LPB2) works with the K3,
Yaesu (FT-950/2000/5000) and Kenwood and supports PowerSDR/IF and NaP3.
The newest and most popular SDR for use with LP-PAN is NaP3 by
Pete, F5VNB. It is freeware and based on WU2X's version of the FlexRadio Systems PowerSDRTM software, but includes some components of
PowerSDRTM 2.0.16 as well as new skins that Pete
developed. The feature set includes the best features of both of the
above programs, plus one really nice feature of the Elecraft P3...
Fixed Tune mode. This allows the user to select a section of the band
to display, then allows tuning both the VFO A and VFO B cursors over
the display without the band segment changing. It also provides
extremely high resolution when zoomed in, which makes it
quite usable for tuning digital modes like RTTY and PSK.
PowerSDRTM v126.96.36.199... http://www.telepostinc.com/PSDR.html
really good SDR for use with a rig's IF output is FlexRadio Systems PowerSDRTM software v188.8.131.52, modified and
supported by WU2X.
It incorporates a
specific improvements to optimize its use as a panadapter, and
integration with a real radio. Please help Scott and his team with
their work on this
software with a donation if you like it.
A relatively new freeware entrant is TRX-Pan from Laurent, F6DEX. It
not provide an audio output of the tuned signal, but has some very nice
graphic display features for users of rigs like K3 and FTdx5000 who
audio output. Larry, N8LP is a software contributor to this program
as well. It is less cluttered and easier to configure than FlexRadio Systems PowerSDRTM software v184.108.40.206. It interfaces to either LP-Bridge or
This is a unique and popular program from Alex, VE3NEA that is used to
decode an entire band of CW signals and provide call signs and
clickable spots to tune your rig to each station in the band. It can be
used standalone with LP-PAN or in conjunction with LP-Bridge and one of
the above SDR apps. This software is not free, but is relatively low
cost. Go to Alex's CW
Skimmer web page for details.
