2024 10m QRSS Challenge: - VE6NGK 26th Feb

As part of a challenge for 2024, I've decided to see how many QRSS signals I could capture on the 28 MHz band during the year. On the 26th of February, I managed to get a good capture of VE6NGK in the city of Calgary in the province of Alberta, Canada.

As can be seen from the image above, there was quite a bit of frequency drift on the QRSS signal. In reality, the signal only drifted upwards about 5Hz over the space of about 8 minutes but in the world of QRSS, these small changes are easily visible.

About 20 minutes later, I got a second screen capture when the signal was stronger.

The distance from Calgary to my location on the south coast of Ireland is about 6620kms. The propagation mode was probably two F2 layer hops but what make this path more of a challenge is that it goes well to the north.

I also saw NM3ER in New Mexico but I was unable to get a good screen grab. Another day.

In summary... That brings the QRSS tally so far for 2024 up to 14-callsigns & 8 DXCC.

14) 26th Feb 2024: VE6NGK

Addendum: Kam, VA6CA reports the following... "VE6NGK is my other call. I was running 5W at the time I believe. Was at 500mW at the beginning but not getting anywhere.

Below is the transmitting station.  It's a homebrew project using components from my junk box. The controller uses TTL logic chips. and the dual tone audio generator (the bottom board) uses two "tuning fork resonators" at frequencies 410 Hz. I physically trimmed one to get the audio tone frequency difference I need. The 410Hz was 4X up using PLL to get the output harmonics outside the FT817 SSB filter to minimize splattering."
