I've used an SDR-IQ with SpectraVue software for years with my K3 and K3S.  I "connect" multiple logging programs, RTTY and WSJT with LPBridge. (I know the 'IQ is discontinued but they show up from time-to-time.  I have three of them)

I find SpectraVue to be most like the hardware spectrum analyzers I used for years in my career. I've tried most of the other SDR programs, both with the SDR-IQ and other hardware. I dislike all of them.

I'm one of those guys that had the LPPan 2.   And it was terrible (sorry Larry, your other products are great!).  It did the job, not very well, and required additional sound device hardware to plug into and was annoying to get going or move around.   The $100 SDRPlay does the same job without the $150 sound box, without all the cables (just one USB, and one to the IF out).   And I've since bought the P3 because it always works and does most of what I want.  I do keep the SDRPlay attached and ready to go for additional functionality with software like NaP3, Win4k3Suite, etc.     I dumped my LPPan II, sound card, and all cables for something like $150 and I've been much happier ever since.   

That and they don't make them anymore (or haven't since October).

Barry -
I followed the link to N8LP's web site where it states LP-PAN production ceased just before Halloween 2019.  
His focus now is on his station monitor and power meters.
SDRplay RSPx with N2IC's waterfall band map ($150 or less) has been my solution for almost 2 years. 
I run it on a second 32 inch monitor with N1MM on the primary monitor.

The entire design team is working from home.  Great, but what happened to those employees who are not on the design staff?  I realize Elecraft is a small company and not Google sitting on $120 billion in cash.  However, this K3 owner cares about all Elecraft employees.  Were they laid off?  What about their health insurance?

I got my K3 back just in the nick of time.  I had corroded contacts in the PA section and they were replaced with gold contacts.  Your employees made this radio like new!  I built it in 2010.  I may keep it another 10 years.  I understand the K3 will be phased out which is a logical decision.  Can you assure K3 owners that Elecraft will keep repairing K3s in the foreseeable future?

Thanks you and very 73,

As Eric alluded to, the entire Elecraft design team is safely working from home. We're busy adding new capabilities to the K4 and testing it in real-world conditions. (If it weren't for the lock-down, I and other early users would still be inviting operators over to try it. Previous demonstrations have led to amazement over the sound of the receive audio quality, among other reactions.)

 

With its new, faster DSP, versatile architecture, large display, and essentially unlimited code space, the K4 can offer features that go far beyond what we've been able to offer before.

 

Here's a sampling of what this will mean for SSB users:

 

*** Optimal audio

 

The K4's RX and TX passband in SSB modes can be configured to be flat from below 50 Hz to over 4 kHz, with none of the drawbacks of crystal filters (delay, ripple, passband edge effects). Easy to use graphic TX/RX EQ and other bandwidth controls allow the operator to tailor the response per-mode and for different microphones. The overall effect is full, rich audio in both transmit and receive -- the latter in full stereo.

 

Wider transmit and receive bandwidths can also be configured for digital audio modes, ESSB, and AM, at the operator's discretion.

 

*** Exceptional ALC performance

 

The K4 uses a new ALC system designed to completely eliminate power overshoot and varying loop dynamics. This makes it both easier to adjust and more compatible with external amplifiers.

 

*** Multi-parameter transmit metering

 

In voice modes, the K4 provides clear bar graph displays of all four transmit parameters simultaneously: power output, SWR, ALC, and compression (processing level). Real-time numeric readouts of power, SWR, supply voltage/current, and PA temperature are also available.

 

*** Foolproof split transmit indication

 

You'll never lose track of whether you're in SPLIT mode with the K4: all four transmit bar graphs are grouped either on the left (non-split, i.e. VFO A = TX) or right (split, VFO B = TX). TX icons are also clear and unambiguous.

 

The K4 also allows full cross-band/cross-mode operation in both split and non-split.

 

*** Versatile audio I/O

 

There are mic and headphone jacks on both the front and rear panels. Some operators prefer to use the rear panel connections to avoid cluttering the operating position. Audio for both voice and data modes can be either analog (LINE in/out) or digital (via USB or Ethernet).

 

*** Large DVR memory

 

The digital voice recorder draws on the K4's large pool of flash memory, allowing virtually unlimited expansion for both transmit and receive purposes. There are also new, easy to use playback controls.

 

*** Redesigned PA stages

 

All transmit stages have been upgraded, with improved biasing, parametric monitoring, and T/R sequencing. Hardware is also in place to support closed-loop amplifier IMD optimization, both internally and externally.

 

*** Support for future operating modes

 

With DSP and MCU horsepower to burn, we'll be able to add new voice and data modes in the future (and even new bands). The K4 is designed from the ground up for extensibility in both hardware and software.

Wayne

Try SDR-Radio.com

It does not support the LP-Pan device but it does support sdrplay devices beautifully.

Re: Panadapter Software for the K3s

 

Hello John,

I am using a softrock IF-lite for the K3 ($20 or so), my pc soundcard and for software (your question) : NAP3.

NAP3 does an excellent job as panadapter display and looks wonderful, mouseclicking works for main and sub rx so no need for anything else.
All com-ports necessary are connected via LP-bridge. (much to read about this on N8LP's website)
I can run N1MM, CW-skimmer, NAP3 and MMTTY simultaniously. No matter what I do, all programs and my K3 follow.
Working with this set-up for a log time, don't know how many years already.

The simplest and most effective means of using a panadapter with a  K3s is to get the P3 from Elecraft.   They work well and are very easy to setup.  No computer skills needed.  Along with the built-in display, there s the option for a SVGA video out that allows you to feed the panadapter display to a VGA monitor.  I have a 12” monitor connected to the P3 which makes it easy to see the display without a large footprint;  you can certainly use a larger display than that.  

I initially tried using the LP-PAN2 (http://www.telepostinc.com/LP-PAN.html) back in 2014 when I got my K3 system which is a combination of hardware and software that runs on Windows to provide a panadapter display on a computer screen.  It runs only on Windows and uses the sound card to provide audio into the computer from the LP-PAN2 hardware that is connected to K3 to provide I/Q input.  The key is the sound card which must meet specific criteria.  As I operate remotely, the potential of having a Panadapter on my computer screen was appealing because i could connect to the PC in the shack remotely and see the display when not in the shack.

However, I was frustrated by the whole thing and never got it to work properly.  I suspect the recommended sound card “interface" that I purchased was the culprit, but who knows.  Given that I was at my amateur station site only about 25% of the time, I did not have much opportunity to troubleshoot and follow the learning curve despite the support that I did receive from Telepost (including sending the LP-PAN2 back for evaluation/repair).  In 2015 I  gave up and got the P3 and have been satisfied with it ever since when operating from the shack. Unfortunately, this also means I don’t have a panadapter capability through my K3 system when operating remotely.  And I’m not knocking LP-PAN2 as others have been satisfied with the product. 

I’m a Mac user for 80% of what I do with a computer (the exception being primarily amateur radio)  but I’m unaware of any panadapter package (hardware and software) that is designed for the Mac.   Others may have some thoughts on this.  

If you’re not operating your K3s remotely and you’re not comfortable with dealing with Windows (e.g. drivers, configuration, installing applications and troubleshooting), for ease of installation and use, the P3 is difficult to beat with the K3/K3s.  Yes, the P3 is more expensive than the LP-PAN2 approach, but ease of use and avoiding frustrations with Windows and software also has some value.  Just as Apple products benefit from having the manufacturer responsible for both hardware and software, K3 users benefit from Elecraft being a source for major subsystems (transceiver, tuner, amplifier, panadapter) where ‘everything works.” Less hassles/frustrations is something to consider if your budget will allow it.
