Fabulous work, Now, do two more things : 1. Using a volume control in the front end, measure the resistance at various settings and read out the readings on the analog port. 2. Using this as a chart,

Any stray adapters left? Discovered a couple of spare boards in need of the dds variety that seems to have become unobtainium. Ross vk3ucr

Dave that’s a great idea with the fan powered on only when in transmit I might do the same thing here. I’ve got a few very small fans here salvaged from somewhere and they are quiet too. Have you

What's the problem? 73

You are correct. However, they've already been freed up. The stock Raduino has 4 data bits to the LCD.

I was under the impression that the existing 2x16 LCDs could be used in 4 bit mode or 8 bit mode which would free up 4 pins. Many alternatives ....OLED displays with IIC interfaces, etc etc.....but

Thanks for the advice Skip.? Did some long transmissions on 40 and indeed the power transistors did get pretty hot. I had not noticed it.? Went to my box of computer parts and pulled out a nice

That's really neat! How long does it take to do the scan? How often do you do the scan?? -- John - WA2FZW

Very Nice, Curious if you are using DSP on the Teensy 3.2? Kinetis K20 Arm4 core, or using the SGTL5000 Codec for processing.? I hear great things about the Teensy DSP Audio library, but from what I

Good work. I also scratch-built the uBitx and seems to be working OK on receive,?still testing?out on transmit ?. . .?could you share more detail/photos of your build?

Hi All: Here's an experiment that might be of interest, especially to anyone thinking about one of those fancy ICOM 73000000s.? The goal is to build a crude panadapter into my BITX rig without

The problem with remaining pin compatible with the Nano is that there aren't enough of them. Maybe stick that si5351 on the main uBitx board where it belongs using a little itty bitty board glued to

I have bookmarked it. Looks like there is a lot of good information there. Thank you. Regards. Max K 4 O D S. I've Never Lost the Wonder. Antique Electronics Site:

Gary, I agree that none of the others are even close to matching the Nano pinout .....except for the Protoneer. And saving an interposer board would be great. Boards are in the mail .....I think. 73

Interesting Radu, have you thought of using a 10.7 IF instead? It might be easier for image rejection but more important is it could be fed from the junction of C40, R37, and 12MHz Xtal filter. At

I stumbled across the Protoneer last week when searching for a controller upgrade. I was unable to find a Blue Pill or ST board variation that was _pin_ compatible with the Nano. Maybe I didn't look

I got a Blue Pill with the 48 pin TQFP STM32F103 about a year ago, got it to speak Arduino just fine. Of course, some Arduino libraries aren't ported, but it's a major step up from the Nano. Blue Pill

CW 99.99% of time? ... now where did I put that mic ...

If you google "git for windows" you'll find the windows version of git and a bunch of other links, eg. git for mac, ... Vince.

Thanks Bob!? The "N/C" meaning "Normally Closed" makes sense.? Should have realized it myself! -Jonathan
