Running SDR 3 on one computer and have JTDX set up on another computer. All is well except receive audio is pegged at the top. Is there an adjustment in the program or computer somewhere to turn the receive level down somewhat??

You are using the most current version of JTDX correct?
And I recall using the AGC to raise / lower the RX shown in JTDX and trying to set it 160-180 range if I remember correctly

I think Rick is correct. You have to reduce the signal out from the SunSDR. In addition to the AGC I have used the attenuator. Also, the notch filter is simple to use and does a great job of taking out the QRO guy. If there's one or two very strong signals notching them out often brings the level down nicely.

Use only AGC: off in esdr and set needed audio level by Agc slider (45dB is good starting point) esdr will remember settings for every band separately. No need to use attenuator. I even use constantly +10db preamp.

I found that the RF slider nicely controls the receive audio level to the suggested level, however, I am at a complete loss to find how to adjust the xmit audio level when using TCI interface and JTDX.
There must be an obvious solution I am failing to find.
When I monitor my signal on a separate SDR (Hermes Lite) on a separate PC running its own version of WSJT-X, there appear to be numerous spurious signals on both sides of the xmit frequency. This is independent of the RF Drive level, i.e. they are just as prominent at 5 watts as at 20 watts, which leads me to believe this is an audio overdrive issue that I need to solve. I have been unable to find any guidelines as to how to properly set and adjust the xmit side for FT-8 with the SunSDR2DX.
I don't want to be that guy with the dirt all over the FT-8 spectrum.

Hi, Tom.
Please make sure you use the latest JTDX version 2.2.160.
It should work OK.

Rome,
I am running JTDX version 2.2.159. I will find the more recent version and install it.
I am trying to understand more about TCI though. A couple questions:
1. Is there a way for the user to adjust the transmit audio drive level (coming via TCI) that I am not seeing?
2. On a whole different subject, it seems it would be possible to implement a MIDI to TCI translation layer to allow MIDI control of the xcvr, right?
I have downloaded the TCI software client info and will take a look at it when I get some time.
Thanks, Tom

BTW, I am enjoying my SDR2DX very much!

Hello Tom.
The link to Google Drive with the latest version is on our web-site – eesdr.com/en/software-en/software-en
To your questions:
1. Yes, TCI client can do that via commands: DRIVE, TUNE_DRIVE.
2. It could be possible, in theory, if you'll implement it in the client.
