Thank you, Oliver, your fixes all worked very well. Those that you fixed have been “Bugging” ha, ha, me for a while. Rick Price KN4AIE Sent: Wednesday, April 9, 2025 6:30 AM To:

Duane: There should be no stock as it is a "Print on Demand" book. Tell then to check for Chapter 20, because earlier versions don't have a chapter 20. Jack, W8TEE

Thanks for all the replies.? I have downloaded and printed the Assembly manual that Greg linked (thanks!). ?? I'll let you know how progress is going with the resurrection of this T41.? I will be

Hi Jack. I ordered it on April 5th.? It was delivered on the 8th.? I plan to return it.? Was going to give them a couple of days to deplete what stock they have. Duane - K5CA

I've fixed this one too. Added a call to ResetTuning() at line 33 of MenuProc.cpp -- i.e., reset the tuning right before calling CalibrateFrequency(). See the changed line on GitHub here:

OK, I tracked it down and fixed it. Update code here: https://github.com/KI3P/SDTVer066-9/tree/main I removed one line in Display.cpp under UpdateInfoWindow(). There was a call to

I've noticed that the noise floor in my receive spectrum varies, too, when I change the grounding of my radio. I’ve been fighting this a little bit too. Running heavy shields between the boards

I've noticed that the noise floor in my receive spectrum varies substantially when I change the grounding of my radio. I presume that the same thing is happening on the transmit side. I've not been

No reason for it, it's just another bug that needs to be squashed.

Thanks, that's definitely a bug! I can recreate it on my radio. Will track it down and squash it.

Oliver, This is similar to what I am getting. Do you know how to get rid of it? I notice that when I connect my HP signal generator, the background noise disappears and I have a clean sine wave with

Dave Cripe made some changes to the 4SQRP boards and they were V09 versions. Greg has provided a link to the build instructions that 4States provided that show V09. I thot that some in my kit were
