ND6T/K5BCQ Automatic RF Gain Control aka "Kees" Board

Dale Hardin
 

Anyone have one of the "Kees" AGC boards laying around in excess to your needs?  I have a uBitx V5 on the way and I want to install this board.  Since Kees sold around 450+ of them; (1)They must work. and (2) There must be a few unbuilt kits around.  Thanks in advance, Dale KS4NS

I am sorry I missed the contribution of Joe Puma. I thank him also.

Hi Morris,

Just google for "usb connector pinout".  If you click on the images tab, you will see lots of helpful pictures to show how the wiring is done.

Sorry I'm pretty new at these things. The ground wire connecting to the volume control, or to the DC connector? They look fine, what would be a way to test to make sure? Or anything to look out for?

Thanks!

Thanks for responding David.
What I was thinking was to plug into the raduino with a mini and solder the other end to a panel mounted usb jack, There is a usb jack like that in the stuff that came with the rest of the ubitx stuff. I was hoping someone had done the same or similar and had the wiring layout.

Thanks

Or depending on which ends of the cable you want to hard-wire, you could chop up a cable and solder it to the Nano or the panel.

Thanks for the links and information. Each time I deal with an issue like this I learn a bit more.

Joshi,

Thank you for the good news. Not sure what was going on there. Let me know if you see any other issues. The December release "should be" exactly the same as the June release with the replacement of that one .png that had a "9" instead of a "0" in the manual frequency entry screen.

Re: #uBitx #v4 and #sdr panadapter #ubitx #v4 #sdr

Following my comment in the http://www.hamskey.com/2018/04/how-to-connect-sdr-rtl-sdr-to-ubitx-and.html?showComment=1572969252472#c7109846895242820018 thread, I tried SM0JZT's method using a kit from G4HUP. See https://ubitx.net/2018/07/21/full-sdr-receive-with-g4hup-buffer-amp/ and https://groups.io/g/BITX20/message/54410 for some notes, and https://www.sdr-kits.net/Panoramic-Adaptor-Tap-Boards for the amplifying tap board.   The nice thing about doing it this way is that it is before the 15kHz wide filter so you can deliver more bandwidth to your SDR.

I piggy-backed a two-pin header across R16 of my V5 and stuck that directly into a 2-pin socket I soldered onto the G4HUP 50MHz panoramic adapter board.    R16 performs the same function in V4 as it does in V5, so it should work the same way.

Wiring up usb to back panel - V5

Morris Ford <morrishford@...>
 

I'm looking for wiring information for cabling from the raduino to a usb connector mounted on the back panel, ubitx V5. This is a 'cut the end off a cable and connect these wires it to the connector' type information.

If everyone would rather that I figure it out, I will understand.

Thanks in advance

Sorry, one more comment, Ron (W4DNQ) stated he had an enhanced display. However, the status line on bottom says he is compiling for a basic. An Enhanced Nextion will not read the tft file for a Basic. Think the GPU is even different between the two....

Ron, any reason you cannot use the tft files I uploaded?

Thank you all for interest in the issue with 5" enhanced Nextion display.
I again used the fresh download and now it is compiled successfully.
Thanks Mark AJ6CU for such a wonderful addition to CEC firmware.
I will install and test it with my UBitx.
