In SolderSmoke 109, I did a little experiment. Normally I do some audio processing using Audacity's Equalization option. In all of the recent episodes, I have been using an equalization curve similar to the one shown above. I drop off the low frequencies (to get rid of the Popping P sounds) and I put a notch at around 3500 Hz in an effort to get rid of the problematic SSS sounds. I had my doubts about the effectiveness of all this. Partly in an effort to save time, SolderSmoke 109 I dispensed with the processing. I immediately got a couple of e-mailed signal reports saying that the nasty SSSS sound was back.
I really can't hear it on my computer. This may be related to different sound cards. And some high frequency hearing loss that I picked up on the rifle range may be involved.
If you can, please compare the sound quality in SS108 with that of SS109, and let me know what you think.
Dean, WA6P, and Bill W7AAZ, going to send me a passive audio filter that we hope will help.
On a similar note (!), I am looking for a circuit for a simple audio signal processor for use with my DSB rigs. I need something simple that will provide both clipping (probably via the standard two diode arrangement) AND audio frequency selection. The ability to put upper and lower limits on the audio frequencies is important in DSB rigs, because they lack the crystal filters that do most of this work in SSB transmitters.
