Re: Wiring up usb to back panel - V5

David Forrest
 

Google for a mini-USB to panel adapter -- Instead of hacking a cable and connector to adapt the Arduino Nano's mini-USB jack to a panel jack to plug your computer into, you can use a ready-made cable.  On Amazon, there looks like mini, type B or type A panel mount options available for under $10. 

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.

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

Here is a pic of my setup, solar charges battery operation. It’s really working great on with the SWR working

Great!

But giving credit where credit is due, would not have had this if Joe Puma had not got it going. His work showed me the path to complete.

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.

Enjoy the build and operating the rig.

Don't fear initial lack of AGC. This rig works fine without it. I added agc only to address tuning across a band. These audio agc circuits only impact signals above S8 or so. I use the vk3ye agc BTW. Enjoy exploring mods after using the rig.

I'm looking to connect an SDR to my uBitx v4 for use with the CEC firmware. It looks like CW-1 might be a good connection point? It looks like CW-1 and CW-2 are the two 2-pin headers near the crystal filter. Is this an appropriate place to tap the IF?

The technician guide is free, the general and extra cost money. But well worth the cost.
