How I made QRSS connections to KV

Spring OM1II is the author of the following article:
Visual CW, or slow telegraphy, this is how the abbreviation QRSS could be explained. This operation is mainly used on the VLF band 137 kHz. Few people know, that QRSS also goes to KV, although in very little activity. I surfed the internet a bit and read about a few frequencies, where it is recommended to work with QRSS – 3585, 7037 a 10140 kHz. I downloaded the programs from www.qsl.net/on7yd and started testing the reception first on 137,7 kHz. For reception I used the ARGO program from I2PHD/IK2CZL and for transmission I prepared the QRS program from ON7YD. Success came, I saw some connections on the monitor, I heard some stations (the TS-450SAT device and the Pyramid antenna at 80 meters). Subsequently, I started testing for KV.

 

I figured, that as long as on 137 kHz is an effort to increase performance, so at KV there is an effort to use minimum powers. I started broadcasting later with 5W, 1W and finally ended up on 300 milliwatt. It required a lot of patience, after all, the dot lasts in the QRSS3 mode 3 seconds . The whole CQ OM100TS K challenge went approx 6 minutes. So you can imagine, what's the tempo. which is better than the FT-1000MP, that I broadcast myself an incredible amount. Fortunately, the computer was broadcasting it for me. I also used “sebaanoncovanie” through DX Cluster and success came.

After a year of irregular broadcasting under OM100TS on QRSS3, I managed to do it 4 which can be linked with AirScout and operability (1xOM, 2xDL a 1xG). It's no glory, but what followed after that, literally shocked me. I received a picture via email from Australia from VK6DI. That day I broadcast on 10140 kHz, performance 300 milliwatts to the AP8 vertical antenna. The result can be seen in the picture. You don't try?

Equipment on the receiving side VK6DI – Ten-Tec Receipt, 40m dipole 9m above the ground. Performance of the OM1II (OM100TS) approx. 300mW to vertical AP8. The type of device does not matter, however, the condition is high stability and precise tuning. Signal width at that speed, rather it should be said slowness is about 1 Hz. The program has a wide scale 100 Hz. It could easily happen, that the opposite station can be tuned outside the given scale. These are very weak signals, which we don't need to hear, because they can be below the noise level. But why does the program evaluate them?, you have to ask the mathematicians.
