This adventure into the world of QRSS started a couple of years ago when I was listening to a podcast called "SOLDERSMOKE" which is produced by Bill Merea I0/N2CQR. He was having all kinds of fun with his Manned Experimental Propagation Transmitter (MEPT) in Rome, Italy. At the time I couldn't figure out how his 10mW, upside down, QRSS signal was going so far when I was having problems talking out of the USA with 30 watts using the latest weak signal digital program. Listening to him telling about his adventures with QRSS, the BUG bit me big time. I was off searching through my junk boxes (there are more than one here) trying to find the parts to build my own QRSS MEPT and really see if all the claims of long distance signal detection was true. It has been a magical experience since then. With this website, I am going to try to guide you through the steps I took to get where I am today. I will try to fill you in with all the websites and information that I spent months finding on the web. Some of the sites I used are no longer active. Like any area of Amateur Radio, Some jump in and have fun for a while and then move on to the next project that catches their fancy. I am somewhat that way but for some reason I can't explain, I am still doing this one almost two years later and I have recruited a few friends along the way.



I started the first week trying to figure out what I needed to get started. I would need a good weak signal spectrum analyzer program that was easy to use. I would need to hook up my ICOM 706MKIIG to my computer with a PSK type interface so that I could get the audio output from my radio to the spectrum analyzer that uses my sound card to process the incoming audio in my computer. These two hurtles were easily accomplished as I had been using my computer for communications using the PSK-31 digital mode and the radio to computer connection had already been made. Now to find the Spectrum Analyzer program. There are three good ones that are free to use on the internet.:

ARGO - downloaded from the easiest to use. Most of us started with this program and were hooked immediately.

SPECTRAN - downloaded from the same website as ARGO is a more sophisticated spectrum analyzer that is a little harder for the beginner to setup but works very well.

SPECTRUM LAB - downloaded from and is pretty much the ultimate audio spectrum analyzer.

Another way to listen in is to use the online QRSS Grabbers around the world.These operators use their equipment to receive the signal and then place a screen shot of what their receiver heard onto a website. I2NDT came up with a scheme to display thumbnails of all the grabbers so you could have a quick view of a large number of stations. By clicking on the name below the thumbnail picture, you can view that grabber's latest screen shot and look for your signal. This website is very valuable when your looking to see if your transmitter is working or how far away you are being heard. It is also useful when comparing antennas and adjusting your power output or frequency.
It can be viewed at:
There are also many Grabbers that are online and not on the compendium and you will learn about these as you go along and can add them to your favorites on your web browser.

The key to really enjoying QRSS Operations is information. One of the best sources of information on what is going on, who has seen who, what stations coming on the air or going off the air, is sent out by the KNIGHTS OF THE QRSS reflector. You can join the KNIGHTS at anytime. It is a free club group and you can receive via emails of what other members post to the reflector. You can Join the KNIGHTS OF THE QRSS here:

There may be other QRSS Operators that you run into on the air or at a Amateur Radio Meet. Most of us will help "Elmer" you to get you where you want to be in the QRSS Realm. We are mostly avid "homebrewers"and experimenters. But we really like to spread the word and help new operators get started. All you really need to do is ASK! The one thing we not is mind readers. We can't tell you have a question about QRSS operation or equipment by looking at you. The squeaky wheel does get the grease.

So, I picked ARGO and went to town listening at different times of the day and night for signals to appear on my spectrum analyzer screen. It didn't take long before I saw one and sent him an Email with a screen shot of his signal on my screen. Mission accomplished, I had seen some one, But how are they going to see Me?

I needed a MEPT transmitter.
