Yes, setting the screen for 3.5" in the editor will let you use it, it just won't be formatted for the higher resolution 3.5" screen.

I damaged the Nano on the?Raduino board (bad wiring job on my side unfortunately). Is there any place to get a replacement Raduino board (I could solder in a new?NANO if need be, but would rather

Thanks for all the feedback and suggestions.? I haven't had time to work through everything yet, but here is what I have learned: - I get similar hum on a SLA battery.? The voltage is a bit low

Having a blast on 20, with a W4OP mag loop indoors.

Hi Darren, using your 3.2'' hmi file I compiled it to my 3.5'' with Nextion editor, and my display is now larger than before,as large as yours. Thank you very much. But of course I expect somebody

A couple of small notes: 1. Be sure to replace "User" with your windows user name in C:\Users\User\AppData\Local\Temp\arduino_build_692458/JackAlV050.ino.elf or you might have trouble finding your

I had the tx relay get stuck on my ubitx. I replaced it with a standard relay and got it working fine. Might be way simpler than trying to adapt another component.? Got them off ebay from china in 2

Hi Kevin, The VU2SPF solution uses the MCUfriend type low cost touch tft which plugs straight into the Mega 2650 rather than the serial Nextion display. 73 Bob GM4CID

Perhaps a future schedule could include a CW/RTTY calling frequency so that Technician Class licensees can participate. 73 Mike KK7ER

hi, Does this work with the Nextion Enhanced 3.2" screen ? kevin rea lancaster, calif. k6rea

BITX QSO Afternoon/Evening, Sunday, August 26, 3PM & 7PM Local Time, 7277 kHz in North America, 7177 kHz elsewhere. Join us as we make contacts with our BitX-40s or uBitXs or anything else on 7.277

They are not shorted drain to gate.

I see Darren, thank you very much for your quick reply. I thought it was possible to scale as a whole at once for who knows to do mods. Hope someone who has 3.5'' regular nextion display makes it...

Hi Don, I am happy to hear about your success. It was a real challenge squeezing 1200 watts out of your MicroBitX <evil grin>. 73, Bill KU8H -- bark less - wag more

What size is the PCB? Can't seem to get a quote without it... (Knocking my head against the wall...)

Thanks Ron, We're not planning any DSP audio additions in the foreseeable future though. Jack Purdum, W8TEE has all that nicely implemented in his "Jackal" board and we don't want to butt competitive

The resistors check fine. Is there an easy way to check the IRF510 transistors?

Uh oh, it looks like R261 and R262 got very hot.? I think I can check them with the DMM.

Added photo of 80 meter T9 monitor ..Tek 7l13 (1 Khz low frequency cutoff) and a photo taken of W7ZOI "wes-alizer" to show that you don't need big bux to see this stuff Jim

Nice effort guys. This is going to be a valuable upgrade to my V4 uBitx. However, in the long run I would like to see a version of your board that includes a high bit-rate audio I2S CODEC, possibly
