T41-EP Modifying V10/11 systems to run V12 software
开云体育I suppose you COULD do that.? You need to bypass the DIV by 4’s is all.? There are some additional subtle things (like CW generation) but a little surgery will, indeed, make it work at least on SSB. ? ? Dr. William J.

Is there any basic reason why V10 and V11 board systems can’t be modified to run the V12 software? There are obvious issues. Clk0 and clk1 from the Si5351 have to be run to QSD and QSE Clk2 has to be available for calibration and CW The big question, for me, is whether there are other fundamental changes such as use of different Teensy pins for existing functions etc. This is really a question for those who designed the V12 system.? What are the ‘hidden’ pitfalls of trying to convert V10 V11 boards to run the new software and operate on 10m and beyond? Harry? GM3RVL |
开云体育That a lot of work and its gonna be hard to get the V011 QSE/QSD to work at and above 10M just because of the physical layout.? It will be far smarter to just add the new V012 RF board and leave the V011 QSE and QSD for experimentation. ? Here is something not talked about… you don’t have to finish the entire RF board… you can just build the receive part if you want. ?That way all you really need is the MAIN and the RF boards for your receiver. ? ?

Nope... just working hard trying to get the V012 prototypes finished....

Has something happened to this group? The last email that I received is from Sept. 13th, 4 days ago. I also looked directly at the group, and there are no new emails since then. 73.. Howard, WA9AXQ |

Howard:
The group continues to be very active. The lull is likely because of the several factors. First, to my knowledge, all but one bug have been eliminated from the Master Bug List. In the past, this was a major source of posting activity. Second, Dr. Schmidt is waiting for reports on his set of PCB for the T41 from the Beta testers. He doesn't want to release their design until he has enough data points to make the call. I have a set, but am being delayed as I rework the assembly documentation for the T41 kit from 4SQRP. Third, the task of redoing the T41's kit documentation is taking longer than expected because of changes that were made to the kit but not reflected in the BOM. David Cripe, NM0S, who is the lead on the 4SQRP T41 Project, was forced to make some design changes because of the supply chain problems manifested by Covid-19 and the worldwide chip shortage. He's waiting for my pass through the T41 documentation. I will say this: because of the earlier work of the Beta testers and other members of this group, the performance of the T41 rivals rigs costing up to 10x as much. I have made contacts with the T41 on every continent except Antarctica. It's been a long journey, but it will be more than worth the wait. Jack, W8TEE |
开云体育John, I’m currently writing that list for the V012 boards.? I hope to have it done tonight now that I am back from holiday.? I too have used the AD831’s to great success, and the rest of what you have done sounds amazingly similar to what I have.? I also just got a FPGA test kit which opens a lot of doors.? I think it may be the next step. ? ? Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ ? Owner - Operator Big Signal Ranch – K9ZC Staunton, Illinois ?

I realise it is dynamic with items added and removed as sorted, I would like to be able to see if issues I have found are included and forward any not so. |
