A Proposal to help WSPR and QRSS at the same time

My name is DAVID R. HASSALL WA5DJJ. Since November of 2017, I have been constructing a QRSS All Band Grabber that presently covers 160M, 80M, 60M, 40M, 30M, 20M, 17, 15M, 12M, and 10M. My frequencies are located about 100Hz below the WSPR Band on most of these frequencies. I am using this grabber to study the Ionosphere and its changes by watching the signals on my grabber screens. The reason I use this method is that I can see the dramatic changes to the signals directly and get a full time view of all the amateur bands at one time. There is just one drawback to this plan. I am not getting enough signals. I need many more from diverse locations around the world.

So this is my proposal. A number of you WSPR Operators use Hans Sommers U3S and other transmitters that are capable of both WSPR and QRSS transmissions in a given time period. By watching the signals on the WSPR website, I find that most of you put out 1 or two WSPR transmissions in a 10 minute period. I also know that the U3S is easily programmable to do many different things in any time period by changing the program parameters. What I am asking is for you to keep your WSPR transmitting commitments but also add a DFCW or SHORT FSKCW transmission between your regular 10 minute WSPR transmission or in the same 10 minute time frame. By doing this you will keep the temperature of your transmitter more stable and you won't have to use the parking frequency scheme or other methods to keep the frequency constant in the U3S. It will give me more signals to watch than I could ever dream of having. My WA5DJJ QRSS ALL BAND GRABBER is located on the internet at http://www.qsl.net/wa5djj/ and you can refer to it to pick a frequency that you would like to occupy. You just have to add the QRSS frequency and mode to your present U3S frequency programming and turn it on. After your WSPR transmission the U3S will then go ahead and sent the QRSS transmission and stop. Some experimentation may be required to get it to work on multiple bands, but this is Amateur Radio and we are already experimenters at heart. I don't think this additional operation will hurt your equipment but will provide my grabber and other QRSS Grabbers around the world with many new locations and signals to enhance our view of what the ionosphere is doing.

Please consider this proposal as an addition to the many frequency studies, propagation studies, and Antenna testing studies that we all perform using WSPR (including me). It is more of a request for an extension of the use of the individual Multimode transmitters to provide even more versatility in gaining knowledge of HF propagation theory and practice.

I look forward to seeing more signals on the different grabbers and hope that it happens soon. If you would like more information of my QRSS ALL BAND GRABBER, I would be more than happy to forward it to you or answer any questions you might have of its operation and construction.

Take care and have fun.
