0115. S3 to S5 at best. The sharp audio was able to punch through.

The peak is the SSB carrier with strong low frequencys on each side noted in color.
The songs are. Special EFX - Deep As The Night
Eric Valentine - Back To The Groove
3RD Force - Breakout
Look them up on YouTube.

0103 UTC Good S9 hear. Clear audio.
The carrier set point in the transmitter needs to be set lower. The bandwidth is 380Hz to 3.8k. All low audio frequencys are cut off at 380 Hz.

Thanks for the broadcast.

« on: September 10, 2018, 2117 UTC »Where is the peak at 6873.000 Khz coming from? Does anyone know the artist/title or a link to the track so I can listen to the original? Last post on this by me.

That is because it is changing phase at the same time which will change the amplitude by the null effect. This will be most noticed at low frequencies because of being closer to the beat offset of zero frequency. If the receiving SDR was moved up into 20Hz USB it would cut off anything lower and you will not notice the effect at all. If you look at the video closely you will see the SDR is below zero into LSB about 500Hz. By the way there is a carrier that raises up and down with the modulation on SSB. It is just suppressed. That's how sideband works.

The YouTube video says it all. It is left up to how well it can be received. The transmitting station should not limit the bandwidth because some cannot get a good enough signal and can't receive the full bandwidth. As with HF propagation other stations in other areas will receive a better signal and bandwidth. As far as the bass fluttering that is because the receiving SDR is not zero beating meaning it is not exactly on frequency with the transmitting station.
