IQ Decoder for SDR based panadapter system
Available for Elecraft K2* and K3, Yaesu FT-950/2000**, Yaesu FTdx5000, TenTec Orion* and Eagle*, ICOM IC-R8500* & Kenwood with 8.83 MHz IF output jack for SM-220/230 (TS-830,850,870,940,950).*
*Orion and K2 require rig modification to add IF output port. First-run Eagles require TenTec factory installed IF output jack. Recent Eagles come with the jack. TS-830S does not have CAT control. N4PY or HRD is required for CAT control of Orion/Eagle. IC-R8500 (10.7MHz) only available assembled. ** FT-950/2000 requires 3rd party interface board.
See links for details, and Mods for pdf mod papers describing the addition of an IF output jack for a number of rigs. F6AOJ also has a web page devoted to LP-PAN conversion to 455kHz here.
New! Preamp Kit for installation inside LP-PAN. Minimizes losses of the K3 buffer amp and P3 splitter and provides 8dB lower noise floor.
Ordering: Follow this link.
January 4, 2012: We have plenty of LP-PAN kits in stock again, and expect a batch of assembled units early next week. LP-Preamp kits for retrofitting into existing LP-PANs are in stock and can be ordered on the LP-PAN Preamp page, here.

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. 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. PowerSDRTM v1.19.3.5 The one most people use is FlexRadio Systems PowerSDRTM software v1.19.3.5, modified and supported by WU2X. It incorporates a number of specific improvements to optimize its use as a panadapter, and integration with a real radio. It is available from Scott's website (see link below). Please help Scott and his team with their work on this software with a donation if you like it. TRX-Pan A relatively new freeware entrant is TRX-Pan from Laurent, F6DEX. It does 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 don't need 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 v1.19.3.5. NaP3 The newest entry and one that is quickly becoming popular is NaP3 by Pete, F5VNB. It is freeware and based on Scott'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, like TRX-Pan, which makes it quite usable for tuning digital modes like RTTY and PSK. CW-Skimmer 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. Latest LP-PAN Installation/Setup/Operation guide with detailed instructions for installing and using the above programs. |

What are the differences between LP-PAN and the P3?
This is the number one question that we receive from K3 owners. In order to answer the question, and also to monitor P3 firmware changes and compatibility with LP-Bridge, a P3 was recently added at N8LP (see picture below left). To save prospective buyers some legwork (and us some emails), we have tabulated the differences and similarities of the two products on a separate web page. For those who want to cut to the chase, here is the summary...
Performance of the two systems is very similar, with the following notable differences...
LP-PAN: Much bigger screen, much higher resolution, flexible mouse tuning, dual DSP receive, interfaces CW Skimmer, lower cost.... but, more complex.
P3: Plug-and-play, offers future integration with K3, tunable to any IF... but, smallish screen & higher cost.

January 4, 2012: We have plenty of LP-PAN kits in stock again, and expect a batch of assembled units early next week. LP-Preamp kits for retrofitting into existing LP-PANs are in stock and can be ordered on the LP-PAN Preamp page, here.
Software is available from several sources. Some is freeware, some is not. LP-Bridge is available free for download directly from TelePost. The recommended PowerSDR-IF Stage software is available for download from WU2X. There is no charge for this, but a donation to Scott and his team is recommended. Good software takes a lot of time and effort to develop and maintain.
| WARNING: Before
ordering, it is
recommended that you read the Manual
and the Installation
Guide.
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
check out
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.
K3 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 K3s.
Z10000 buffer kit from Clifton Laboratories (Jack, K8ZOA) to add an IF port to the K2, Orion or other rigs.
K2 Mods: You will find detailed K2 installation information in the Z10000 manual.
Orion Mods: Rick VE7TK has posted this paper on Orion modification. HRD 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.
Mods Articles that we've collected describing rig modifications for Orion, TS-440S, TS-2000, FT-1000MP. We do not endorse any of these mods, but provide them for convenience. If the mod requires a buffer amp, the Z10000 mentioned just above makes an excellent choice.
IF-2000 Interface 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.
