Add a software defined radio (SDR) to your transceiver to make a 'real-time' panadapter
Installation is very easy. The TS, as well as other radios, has a fairly complex configuration and uses different intermediate frequencies depending on the band on the which one is operating. In any case, the one described here is the sequence of operations to be done to obtain sufficient bandwidth to make a panoramic receiver around the selected IF frequency. For this reason we opt for the first average frequency and before the roofing filter or intermediate frequency filter.

The point where the IF signal can be picked up can be more precisely identified by means of the wiring diagram as shown in the following pictures. We can use the CN6 connector pay attention to the polarity.
The electronic card of interest is the one called TX-RX1 and it is on the bottom side of the radio. Now we have to look for where to get the power supply. Nearby is the resistance R at the ends of this it is possible to take the voltage with which to feed the IFace. These components are physically close to the CN6 connector from which the IF signal is taken. In the pictures that follow you can see how close are the points where to take the IF signal and the power supply: the installation is really simple.

I assume RF has messed it up as it is not in a grounded box. So, I went to a manual antennna switch in the meantime. So - after a couple years, how is it holding up? Do you recommend it still, would you have any lessons learned or mods to the original to make? I am not sure if the buffer amop woujld still be required with my SDR system, but it shouldn't hurt either - and insurance is always a good thing.
Thanks again for this blog post - it seems a unique entry for FTD panadapter use. Here is a quick update. The signal width is very small, only about 30khz because you are tapping after some filters.
And the signal quality going to the SDR was actually quite poor and noisy, I guess because you are after quite a bit of amplification as well. By far the best setup to me still is using a Softrock Ensemble connected to the RF tap I documented in that blog post and using it as an independent HF receiver.
The signal quality that way is excellent and you can pretty much have as wide a signal on the SDR as your SDR can handle. Myself, I still use this on a regular basis of being able to use the Softrock and the ft side by side sharing the same antenna. It works great. And I would say that yes, the buffer amp is probably going to be required for most any of these applications, because I am pretty sure nearly all these SDR's leak oscillator signals back up the antenna port and that could get back into the FT receiver and affect its performance.
Hope that helps. Than k you sir - I will work on that - need to check to see if my warranty is up yet on the FTD first. Don, Two more questions on specific amp build if I may - First, is your Clifton Labs buffer amp the base version?
I assume so, but if it has any k2 or K3 parts, I need to know that before I order the kit. And then second, what gain resister or number do you use for the R7 for the FTD? Would you change it for better performance? The figures on gain start about 5 Mhz according to the graphs in this PDF, so I don't know if it is required or not. How does the Meter receive do? This chain would be fed by the buffer amp, so I don't know know what gain to use.
True, the Soft Rock has band pass filtering and more bits in its decode 8 bit vs 12 or 14? I haven't opened the radio yet, so I am not sure if there may be room for the board. Thank you sir - Olly - Clifton Labs is not now in business, he stated health reasons for its closure.

When working HF, this is very useful as it allows you to quickly home in on CQ calls and other activity. How do you connect your antenna to both your transceiver and SDR? Unfortunately, it's not possible to simply attach an SDR directly to a transceiver. A switch can be used to flip between SDR and transceiver, but this prevents the use of your main receivers audio signal making this setup a bit awkward.
One way to connect an SDR and transceiver is by using a relay box to disconnect the SDR when transmitting automatically. This page describes how to safely connect a software defined radio to your transceiver using a DXE-RTR-2 relay box to create a real-time spectrum analyser panadapter to your shack.
Before you begin you may need to do some shopping, the equipment required to make all this work is listed below:.
So a power lead will need to be manufactured at home, be sure to include a small fuse to protect the device. Making the lead is simple, but it's annoying if you haven't got any wire, etc. There should be no need to change any jumpers on the DXE-RTR-2 as delivered from the factory set up ready to support the configuration below.
The setup is very simple but must be made correctly for this all to work:. Wire management is a problem because this set-up introduces a lot of extra cables into the shack. This allows for 'point and click' tuning directly through your PC or via the tuning dial on your transceiver. To access this feature, click on the '? Note: To save your SDR just in case there is an issue keep this disconnected when first testing!
If this does not happen as expected then check your wiring and software setup etc. Adding a panadapter to your shack can really enhance HF work.

This is an update of my June review. The rig has performed flawlessly with only one problem, that being the long power cord and bad connectors causing a voltage drop. Easily fixed. Otherwise the rig works superbly day after day, never missing a beat.
The auto tuner has a great range and is the fastest, most reliable tuner I have ever used, The receiver is very good but to be fair the internal speaker is not top of the line so adding an external speaker helps a lot.
Transmit audio and receive are Kenwood "excellent". Overall if you need a full time reliable well performing rig you just cant beat this one. Glad I bought it!QRZ Forums. I am looking to buy a panadaptor that would work on my Kenwood TSs but no results Just trying to hook the rig up to my computer to get the waterfall scope from a sdr play Any help on a working solution would be greatly appreciated.
Does the TSs give you easy access to the IF signal? That's what you need for a panadaptor. W5DXPApr 2, It was effective and worked well - nice having a second receiver as well as the panadapter display.

You can achieve the same result with an external splitter and transmit inhibit switch to an SDR of your choice. Or you can figure out a way to extract the IF directly from your rig. AF7ONApr 2, I have a TS and have never seen a specific article for panadaptor mod. There are numerous discussion on tapping the IF of radios for panadaptor use. There are a few panadaptor boards or projects available. I do not find any in QST archives. I suggest studying the numerous webpages on the topic and then experiment on your radio.
The principles are the same for most analog radios. There is no turn-key solution or cookie cutter guide, sorry. Then you need a SDR dongle. Word of advice, do not buy the cheap ones on Ebay, they do not cover the HF bands.
This is what my pan adapter screen looks like. Here is a video. VE3PPApr 3, Display spectrum demodulation signals, may be processed by other software. Spectrum may be displayed on the computer, any set reception bandwidth, signal recording, save, of course, include playback functions can be arbitrarily set a bandwidth of the filter function. Panadapter is a panoramic spectrum display can be connected to your radio, so you can view your radio station received the entire band up to 10MHz spectrum.
Combining it with the basic CAT controller, can form a powerful tool that allows real-time discovery of multiple signal spectrum, click on any of the signal, your radio will automatically switch to the frequency immediately. Then it is an honor you will hear good news. You can install it yourself, without having to modify your radio equipment. Simply distribution cable to the radio station specified in the location. It is also easy to remove. You need basic skills and the ability to dismantling stations with soldering iron.
