The SSB transmission with TX ERS (remote) is produced on the air with a big delay (2 seconds ...see more) Sunsdr2 Pro Beta 1 and ERS server of 28.10.2022

I can confirm that the TX ERS is working The PTT function is operational When I press TUNE and move the slider, the power is OK with no visible delay. When I press TX (being in LSB or USB) whatever the band, the DRIVE slider at maximum level and I speak in front of my computer's microphone, the power meter goes up but only after a too long delay (2 seconds maybe more).
If I listen to myself in the audio monitor, I notice the same delay (2 seconds ...)

If I say one two three four ... in front of the microphone, at the moment I say four (4), I hear the "one" coming late.

I notice the same thing if I listen to my signal on the air.

I contacted (with the ERS) K3LR and K1LZ on 28 Mhz, during the CQ WW contest this weekend, and that's when I noticed this long delay. I had a lot of trouble to make the carryover exchange...

It's really unusable in SSB for a contest.

The real test of TX/RX ERS was done with 256 kb/s and ping 25 ms), the occupied band is about 0.5 mb/s on the ADSL line.

I also tested locally (ERS server and client on the same computer ping 0 ms) the problem is identical and still there. I didn't notice any delay problem on the reception.

Hallo I also try this and it is a big delay but I also get no power out or very little. Max tuning is abot 45-55 % And making a qso they not hearing me. I get a msg from EE team that I have to update my starter. The starter version is the same that I have but ok I downloaded a new but still same problem Very little power. Have you 100% power when tuning slide is maximum? Regards sm6usu Svante

I did the test remote/local via the server; the reception works well as locally, the transmission is of good quality but with a latency of at least 2 seconds. F1DJY

Hallo Now it is a new update on Starter and that solve my power problem but the delay is there. sm6usu Svante

Here it's the same problem with the delay. I've tried with 3 various computer. Local connection everything works great. Sunsdr2 DX, Beta 1, Firmware 86.8,ERS server 28.10.2022. Best 73 de HB9GBL

I have earlier running Remote Hams and it is same problem. I think as soon we are using internet, we have a delay. Listen to all SDR receivers in ex. Kiwi sdr and If listen to my self direct from my tranceiver there is a delay. But maybe it can be better than it is today. de sm6usu Svante

I have been testing again previous versions on my SunSDR2 Pro with the new remote server that has come out with beta version and firmware 86.8 and the version 0.13.0 alpha dated 07/09/2022 and earlier transmit in real time and without delay. Although the old versións have another problem that you have to hit TX twice to recover the sound when switching to receive.

The rest of the later versions all have a delay of two seconds in remote from the time you speak into the microphone until the audio is transmitted to the air.

Sounds that it is a solution nice. 73 de sm6usu Svante

We are going from bad to worse in the ERS. If in the last versions there was a Delay of 2 seconds in SSB now with the Beta 1.0.2 released today December 23rd when trying to start the remote software in windows 10 it closes itself again and appears busy in the device manager. I had to go back to the previous version which at least half works.

The problem still exists... Anyone is using SunSDR in remote way? This bug makes it unusable....

[ea5ccy]

Yes, the transmission delay issue is still ongoing with the latest Beta 1.0.3 release on 10 February 2023. The strange thing is that if you do FT8 using TCI there is no delay at all but on telephony we still have the 2 seconds delay. Hopefully the developers will fix it soon. We have been waiting for several months now.

Same thing on 10.4 Big delay in ssb (even if it SEEMS that the delay is A LITTLE less if compared to 10.3) almost no delay on ft8
