including NaP3, PowerSDR/IF, HDSDR and TRX-PAN. In addition, it is also
well supported in Tom, VA2FSQ's Win4K3 and Win4Yaesu programs. With
NaP3 and Tom's programs, spots can be displayed in the pan window, and
Tom's programs also support the nifty new Spectrum Display in the N1MM

Kit for original LP-PAN...
Preamp kit is available for original LP-PAN to
weak signal display. The preamp is recommended for use
with Yaesu FT-950/2000 and K3 (especially when used in conjunction with
P3). It's use is optional for Kenwood and Yaesu FTdx5000. The noise
floor improvement with FT-950/2000 and K3 is approximately 8dB, and
with FTdx5000 it is 3-4dB. See Preamp page for ordering details.
*K2 and Orion require rig
add IF output port. See links
for details. First-run Eagles require TenTec
jack. Recent Eagles come with the jack. Argonauts require a factory IF
jack kit which includes a connector and cable to plug into the TX/RX
board. TS-830S does not have CAT
control. N4PY or HRD
is required for CAT control of Orion/Eagle. ** FT-950/2000 requires 3rd
party interface board.

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 except for
very early K3s. The link takes you the Files
section of the LP-PAN User Group. Elecraft offers a mod kit very
similar to this as well, which is incorporated 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 some unique new features. This is our recommended
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.
is a comprehensive rig
control program for the K3 / K3S, written by Tom, VA2FSQ. In addition
to rig control, it provides a very nice panadapter screen which is
loaded with features, including the ability to integrate spots into the
display. The software is not free, but certainly worth looking at for
K3 users. The program also supports the new spectrum display in N1MM
Contest Logger, which provides a pan window with spots associated with
the signals, sort of like NaP3. Tom also has a Yaesu version available
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 much easier to configure than
variations of PowerSDRTM. It interfaces to either LP-Bridge or
Installation/Setup/Operation guide with detailed instructions
for installing and using the above programs.
