Re: T41-EP Modifying V10/11 systems to run V12 software
Thank you for all your hard work, Jack! Our community appreciates it very much. 73, Bart N3GQ

Re: T41-EP Modifying V10/11 systems to run V12 software
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,

There are also several software updates which are being tested by the betas, hopefully to be released soon. -- 73 Greg KF5N

Re: T41-EP Modifying V10/11 systems to run V12 software
Is everybody taking a break from the T41-EP group? 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

Re: T41-EP Modifying V10/11 systems to run V12 software
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

Re: T41-EP Modifying V10/11 systems to run V12 software
Thanks Bill I'd be surprised if a lot of folk don't want to modify what they've already built rather than binning most of it, especially as the existing 10/11 boards won't work on 10m. Certainly if

Re: T41-EP Modifying V10/11 systems to run V12 software
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.

T41-EP Modifying V10/11 systems to run V12 software
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

Open the web page for the group. On the top right click updated twice. That will result in a latest post sort.

Al I'm getting quite confused with the? accolades you are awarding to the new V12 boards.? They seems to be amazing. Where can I see the schematics for all the V12 boards?? It's probably staring me

Re: T41 QSE carrier balance
Woops. Forgot some text - It was recommended to change them to 0 ohms, I did so. So easy peasy to try 3K3. Larry KB3CUF

Re: T41 QSE carrier balance
I did this as recommended at the time- I intend to reverse this and use 3K3 to see if it helps.

Re: T41 QSE carrier balance
*** Won't work. In V12, they're not using the D flipflops. They're using one si5351a clock for each phase. - Jerry

Re: T41 QSE carrier balance
* I *n V12 we have managed to reduce the carrier amplitude on SSB to almost -47dB below a sine signal at full amplitude. This was accomplished using 3.3K ohm series resistors in the IQ CLK0 and CLK1
