NEW BUILD V6 with nextion 2.8 NEEDS AGC! issues and fixes. first time posting

Amie C.
 

I got the V6 and got it all put together and going, so I thought. K3 is dead after trouble shooting and manually  adding the 12v needed it worked, so pulled K3 and borrowed Ka1 then added a jumper in place of ka1. I dont use 10M so its fine for now till the parts I ordered from ebay get here. Maybe HF signals can send parts? 
I then got the nextion screen going and installed. Minor dremel work on the left side holes of the nextion board and fit fine. The push part of the main tuning knob doesnt work well, it sometimes does mostly doesn't so I will separate that to a momentary push button for function. 
The modulation is low, so for that I changed R62 to 4.7K and R63 to 10 ohm. Wala it worked. Any more and it would be too much. 2-3 inches away is ideal. 
My setup does just fine on modulation out. I will mount a small soft fan in the back wall of the enclosure. The finals get pretty hot. The heat sinks are pretty small but for now Its working fine. 
Finding other info has been difficult. I set the bias of the 510's to make sure they were correct RV2 RV3 When I checked they were a bit hi.
RV1 does work well as it gives the ability to control the drive amount.
I am running the CEC v1.200 and finding information on setting the BFO etc was a challenge. I am also using the ubitx manager 1.1 and it has helped. The S meter ability doesnt work so well and not easy to define in the mem mgr settings as to what it actually needs to be set at. It was very muddy when first setup. SO I played with the USB offset numbers until it sounded the way I wanted it to.{ on the edge of the filter}  Nice sharp and clear.Its at the point of being a bit narrow but is working until I find a better way to work with audio filtering. It is never going to sound like a hi dollar commercial built radio and I wouldnt need it to because this is a really cool kit radio and the sky is the limit. Just needs to WORK and have a nice intelligible audio, which now it does. HAPPY DANCE lol. 
I have been trying to get in touch with kit projects to get the AGC board. This radio NEEDS an AGC.It is worth the effort to add AGC. The rest of it is nice, but if I cant get that board then I will either make something or find something for the front end. I have not had a problem with Q90 being shorted from close hi rf, yet! But if do I will pull the SMD and put a 3904 or 2222 in its place. no big deal. I will also be installing a inline fuse or maybe on onside as it needs this! I will use a 3A fast blow as the radio pulls 2.56A {16W} on the cw key.  Very pleased so far. 
I am running the CEC and nexteon and really enjoy that! The reg on the raduino does get pretty warm, Have thought about adding a bit of series resistance to ease it back some, the fix for that is and cool is set the screen off time, cools right off.   Its a great job of setting up and design. I tried to use the nextion compiler to edit the colors of my readout but having issues there yet, says no enough ram? have plenty but is for another day to maybe figure out how to save once colors are changed, the rest works fine. 
I didnt want this long and didnt post any links, rather just wanted to get this out there. Minor issues but over all fun and great little project. I bult a 80M only scout and this is similar but better. Good job on this one! I am a big time kit builder and home brewer. This one is a good one. I hope I can learn more from this foum and get the v6 settled in.
Thanks.

AMIE,

For the Nextion editor, try the Nextion Editor LTS version.  That is version 0.53 if I remember correctly.  For some reason that version will compile the 2.8" screens without the memory error (I assume that the files available were created with a version 0.53 or earlier).

HI amie! I do not know if david has gotten back to you in email, But we have received it! That said we are currently closed and not shipping product due to covid concerns,
We have some decisions to make regarding our safety and re-opening in a timely manner.


Regarding the S-Meter, The kit we sell breaks out an S-Meter tap that works rather well with the CEC firmware. At least from my personal experience!

Thanks for the patience!
