Greetings team and all! 1st,very impressed with the dx so far. Amazing receive. tx audio and intuitive software! My wish would be to see a "downward expander" option in the software. My Anon has this and works incredibly well to suppress background noise such as fans and other annoyances in the shack having zero noticeable affect on the transmitted audio. That option alone would bring it to the next level in regards to the tx audio end. Otherwise, superb none the less.

Looking forward to the upcoming update!
Warm regards to team and all,
Steve K1GMM

Have you tried the Noise Gate on the EQ menu?

My friend Steve ! The noise suppressor for the transmission about which YOU asked is located in the "PROC" module in the Noise gate tab

Having used the the Downward Expender in Thetis with my Anan 7000dle mk2, I can confirm that the noise gate in ExpertSDR does not perform the same function or achieve the same result. I'm also with Steve, and I really missed the Downward Expander (and Diversity and Pure Signal) when I got the SunSDR2 DX. With the far superior UI and remote options coming in ExpertSDR3, if the Expert Electronics team could deliver a downward expander, diversity reception and pure signal, they would have a truly world leading product.

Best

Yes a Downward Expander PLEASE!!!!!!!

And correct the noise gate is not the same thing they are 2 entirely different concepts....

Difference between a “gate” and an “expander” is the degree of level reduction that is applied. Noise gates are aggressive and abruptly cut off the sound when the signal drops below the threshold. Expanders are subtle and smooth sounding they fade levels rather than mute them. expanders tend to sound more natural than gates because they do not completely turn off the signal. Expanders provide more control than gates. It’s much easier to dial in how fast the effect reacts to level changes with intuitive controls. Some downward expanders have a range setting, thatallows you to set the maximum amount of reduction or attenuation, so it never cuts the signal off entirely.

Hopefully this could be added to V3 in near future.

Yes, this feature is really not enough ! I would like the manufacturer to pay attention to this ! Thank you for your comment !In general, I really want people who are engaged in the sound of ESSB to write more about what needs to be done and what works wrong ! Can we create a theme ESSB and SDR from the company "Expert Electronics"? Where will be exchanged settings and correct settings, what we wanted to improve or add to get a good ESSB and we are good and help the guys of the "Expert Electronics" team"

Perhaps Roman can add a section to the forum {ESSB} as a topic in general for all the Expert Electronic rigs

If there was a General section for those interested in ESSB- perhaps it would encourage more sharing of knowledge etc.

Roman: could a section on the forums be added for those interested in ESSB Audio
It could be helpful to the many of use who use Expert Electronic products to share info and recommendations pertaining to ESSB
Thank you in advance for your thoughts on this.

Hi everyone.
1. Thanks for the suggestion regarding the Forum. I'll add a new topic for the ExpertSDR.
2. As I mentioned in the newsletter: "In 2021 we will fill the ExpertSDR3 functionality with ExpertSDR2 functions, plus some long-awaited features."
In 2022 we'll be truly working on expanding the existing functionality.
Роман, Roman

Hello friends colleagues who are engaged in GOOD SOUND ESSB! I want to write that the audio sound analyzer in the ESDR3 v 12 alpha program still does not work correctly, which I am trying to show in my video. I have not once addressed a remark to Electronics Expert company, but I have received only promises of correction The built-in audio analyzer does not work correctly, which does not allow the user to get a beautiful sound..
