Got my DHL box yesterday and connected up my Pi4 and screen, connected an antenna and 12v and the unit was working. I could hear CW and SSB. Figured I'd do the setup today.

So today I go through the operating manual enter call sign, grid and UTC. Then I start learning the controls and notice that I am no longer receiving any signals. No CW, SSB or FT8. Move the antenna to another rig and there are signal everywhere. Reboot the system. Same result.

Not sure what to do. I was thinking of doing a git pull upgrade to newest version but wasn't sure if that would just introduce more variables.

BTW, I plugged in a key, switched to CW mode and the unit transmits fine.

Any suggestions would be welcome!

When something like that happened to me it was the IF gain was reduced. Try increasing IF as well as audio. The IF should be set so the band scope noise is just starting to show.?

The are a lot of hints in the manual ?

Had the same problem I found if I just moved the tuning knob a little it was back to working might try that.

I have played with various settings for hours (AGC, IF and AUDIO) To further confuse me I am receiving FT8 now (see attached) even though I hear nothing with CW and SSB across the band.

Thank you Ashhar. Followed your instructions. No change in behavior. Rebooted. No change.

Unlike the pictures in the manual, I don't seem to have a waterfall display.

Also in FT8 when I try to respond to a CQ, my system never goes into xmit.

Here is my current display.

And I just figured out that double clicking on a FT8 line doesn't trigger a response. I need to hit the enter key. Now it is transmitting.

Yes I heard it and there was a yellow band!
