Looks nice!  What case are you using?  May I ask the current draw on receive?
Cheers,

As you have the AVC kit installed, you canuse it for the S-meter and forget about using another chip and such .

Just hook the ubitx  s-meter wire to the AVC board.  It goes to the first pin where the jumper is on the board that sets the delay.  I forget the capacitor number, but it goes on that junction and the resistors for the time delay .

Works fine after you set up the values using the memory manager.

Well, when I first posted about my uBitx being done, I made a mistake and in the title I typed QCX!  DUH!!!  Well, here I am again with my completed uBitx (not QCX).  I only have a few mods left to do, but right now I am having all kinds of issues trying to get the KD8CEC S-Meter modification done using the LM358 chip.  But I have that mod left to do, the TX/RX pop mod and the AGC mod by ND6T (I think that is right) to do.  I have already did the mod and added an RF gain control with a 1K potentiometer.  I created my own bezel for the front of my homebrewed enclosure. I also added a USB male to female adapter so I don't have to remove the cover to update the firmware.  Still need to get the SD card ribbon cable extender to plug into the Nextion display so I won't have to remove the display to update the tft files on the display.

Quick questions... to add rf gain I just wire the VR to the AGC board? And how do I wire an AGC fast and slow switch?
Thanks,

Hello Bo,

Many thanks for your responds, and yes, the proc is 2560, I will be very happy

if you send me Hex file, I have just some questions about input/output pins

for identify differents functions.

I don't think the source files for the latest CEC firmware have been released yet. I may still have an earlier version.
I think the chip you mentioned is a mega2560. If so I could send a hex file of the previous version compiled for the 2560.

receive works great, but no trans power, #ubitx-help

Don - KM4UDX
 

My beloved and long suffering (like my wife) uBitx has no output power in transmit. 
When I key down the display changes from "USB A:" to "CW"
When I PPT it changes from "USB A:" to "TX".

So all that looks good. But. Neither produces a output at the antenna.

What should I check...fix...validate...replace..?

Background...receive works great!!!!!
CEC 1.9x
no mods beyond the firmware update, which seemed to work fine.
And I got no transmit power on the original firmware anyway. 

Thank you for any help!!!!

Re: Windows Serial Port Problem

Windows 10 might have some driver problems, but the best bet is to buy genuine Arduino products.  People have reported many problems with knock-off "Arduino" boards.  I use genuine Arduino boards with Win 10 without difficulty.  This link at Arduino shows the differences between genuine products and counterfeits.  Yes, you'll pay a bit more, but you won't hassle with problem boards or drivers.

Re: Windows Serial Port Problem

I have probably purchased a 100 clones over the years and, yes, I did have some troubles initially with a few of them, but these were fixed by installing the CH340 drivers in almost every case. Also, it's a bit of a quibble, but non-Arduino boards are not counterfeits, they are second-sourced boards. Counterfeit implies something that is sold illegally as genuine when it is not. As far as I know, the entire Arduino family of boards are Open Source, which means anyone can produce them legally. What would be wrong is to put the Arduino logo on the board, as I believe that is under copyright. eBay has a Nano for sale for $24, and AliExpress has 10 of them for $25. For the difference, I'm willing to (rarely) install the drivers to make them work. I do have my Nano clones working under Win 10, so I'm not sure buying a "genuine" Nano is going to fix the poster's problem.

I agree with Jack, I have some Arduino's and clones,  the main difference I have seen was price. I have windows 10 now and loaded the CH340 driver and it all works just fine.

Have you checked the finals for 12 VDC on the tabs?

Re: ND6T AGC and Click kit wiring notes

Don, ND6T
 

A quick answer: The AGC board is fed by a potentiometer (placed across the receive RF input). The release time may be set by a Variable Resistor placed from J1 to the ground return. Details may be obtained by visiting nd6t.com . Have fun! 73, Don
