The example audio is maybe a bit bottom heavy, but you can clearly make out the difference between this and standard SSB. ESSB sounds like an FM radio broadcast compared to a phone call.
Really nice job covering this topic, too many just don't really understand what goes into it. The example audio was extremely bottom heavy. For people viewing this, I strongly recommend you begin to work with the EQ at 3kHz as narrow bandwidth will show problematic frequency balance much more clearly. Also, you won't hear the bottom heavy emphasis at all unless your computer is wired to a full range stereo and the lesson there is that most people receiving have filters rolling off at 100Hz and playing in a 3" speaker. Those people will find audio balanced as in the example to be muddy and low energy. When you expand out to wide band, you wind up with extremely bottom heavy signal quality that when listened to with narrower filters will sound muddy and unintelligible. If you begin doing EQ at narrow bandwidth and balance there, when you go wider you just gain enhancement and the balance will be much better in implementation.
Can you not use an Adaptive Noise Filtering algorithm running on an ARM chip assuming you have pre-calculated the values for MU which might be 327 if using a divisor of 32768, and using a random number generator to derive the noise to process out the unwanted noise or a sample of the mains hum if that is contaminating the audio.
My buddy with a Yaesu ftdx101mp has open his bandwidth to 4K uses a re27nd through a alpha amp sounds great at 4K I have a ftdx10 which can rx at 4K. Another with a kenwood 890 sound ok at 4K using a senheiser mic. Then we have another member on the Toad harbor net 1.930 who uses a red papaya SDR wired into a pa on the icom 735 can do 20k but that’s a SDR. It used software for a anon with pure signal feedback. Very cool Discussion 😉😉 Wish Yaesu would open the transmitter bandwidth on the FtDx10. They have open the txbw on all the older 1,2,3,&5k series transmitters
Yes indeed interesting discussion…. Re conventional radios I am very disappointed that icoms are still stuck at 2.9khz max tx bandwidth. 101D/MP is doing 4K tx so that is a step in the right direction. I would love to know the reason behind the tx bandwidth limitations with the major players (Icom Yaesu Kenwood) Annan 7000 my fav atm. Pure signal and adaptive predistortion is the best thing since sliced bread. Waiting for EE SunSDR 2 DX to release new software updates which will include pre distortion - at least it has been promised for future soft releases. Over
I have been doing what you call eSSB since the 70's! We played with the carrier point of radios and blow by the filters with processing. BTW Like the T-Shirt. Where did you get it?
question !I use an SDR receiver to control my sound, what should be the received level of the station for proper sound tuning? After all, with a weak signal, you can make a mistake in the frequency balance! and with a strong sound, too, the sound may seem beautiful!!
Neumann microphones in ESSB is a bit silly. As I learned the hard way, high quality large capsule condensers like Neumann are not even appropriate for most FM broadcast stations, for a number of technical and practical reasons. Don't waste your money.
You blokes are boring me senseless. Its simple just do it. I couldn't care less about the history of ESSB or how many call signs you can remember. The future of Amature Radio is innovation and recruiting new people to the hobby. If you maintain this old school backwards looking approach don't be surprised when we loose spectrum and become completely irrelevant. You need to pitch this from the point of advancement for the hobby.
Gavin good point (from a 6yo perspective). 95% of ham population doesn’t know what eSSB is, purpose of this presentation was give broad insight to the world of eSSB. History is important as there are some blokes that have done a lot for this segment of the hobby hence why they should be mentioned. Unfortunately it’s not simple - as you have suggested. It is simple if you want to sound like you are transmitting out of tuna can, however if you intend to play with extended ssb experimentation, traditional ssb plug and play practices won’t get you far.

Hey Gav - the awesome thing is you can just stop watching videos that take the wrong approach or bore you (obviously that's what has happened on your channel) and toddle off and make your own videos to recruit new amateurs the right way and show them your innovations. Or you could if you we'ren't so busy bitching about the people who actually make an effort. And with those 170 views and almost 9 minutes of content spread across 3 videos in the last 12 month and ooh 170+ viewers in that time. You're really pulling the audiences. How many people have watched this video in less than a day? Oh, over 750 you say? Yeah you're right your impact is huge, Ivan and Hayden can just hang up their mics, put their feet up and grab themselves a ukelele and leave it to you. The irony of yet another amateur muso with a guitar calling someone boring- Smoke on the Water (again) and Stairway to Heaven (again) anyone? Yawn.
Actually, IMO one of the great strengths of amateur radio is the fact that there is an intact history of experimentation going back over a hundred years. I personally like hearing the history and context. If you don't like that part, you can just skip to wherever you want in the video.

Does the sound recorded in 43:48 obey 4K50J3E (50Hz...4550Hz) ? Their deep voice seem goes lower than 50Hz.

I suppose that is for use on 432MHZ or 1292MHZ
This is fascinating

with the new firmware tx 4k on the dx10 is possible. hold DNR and MODE buttons simultaneausly while powering up. In the menu TTBF will appear.

Montanacal has some interesting perspectives on ESSB and does so in a humorous way. Check him out.
Hi, I still learning applying ESSB with Homebrew SDR and DAW, maybe in someother time admin could invite me to this Zoom Meeting, tks
