Went to a bookmark I had on https://ubitx.net earlier, and discovered that the domain expired late last month. Bummer! I'm not sure if it was an accidental lapse, or intentional. Whois seems to imply

The uBiTX mic jack is wired as a TRS, not TRRS. You can see the pinout used in the snippet from the schematic, below.

Did you try selecting the "old bootloader" programming option? Reed

Hi Dave, I don't think I put any validation on that field, so it will try and write whatever you put there. If you run too long, it might go off the screen, or overwrite other text on screen. Reed

Hi Dave, The last code change I made was in Dec 2020, so there are some changes since your download. Reed

Hi Dave, The short answer is "kind of". It looks like in the tagged R1.5.1 the behavior is still like the stock software: https://github.com/reedbn/ubitxv6/blob/R1.5.1/keyer.cpp#L115 However, I appare

Hi Tom, You should be able to connect your straight key to the PTT or the paddle voltage dividers. Both go to the arduino, so operationally you can make either work, if they don't already do what your

I bought a key kit from a http://americanmorse.com/ bit back. Not sure if that's the sort of product you're looking for or not. Reed

Hi Henk, There are definitely still some issues and quirks with the last software release I've made. If you have suggestions on improvements, I'm all ears, but make no promises on delivery. If you hav

I actually gave this a go, but discovered that my particular AGC's output wasn't very useful, and I didn't polish the feature at all, so didn't publish the code. Reed

If you don't need super speed or analog, an IO expander would probably make more sense. E.g. https://www.sparkfun.com/products/15099 Reed

The "R" version prefix suggests your running one of my versions. My latest public release is R1.5.1 https://github.com/reedbn/ubitxv6 Reed

The v6 voltage divider pulls at different strengths for dot and dit. If you try and send a symbol that is the stronger pull, there's a small window on the way up and down where the voltage will be at

Yep. That's because the hardware implementation is a voltage divider, and if it happens to sample at the wrong time, it will catch the intermediate state. Reed

Hi Jerry, The only function that should really need adjusting is enc_read. If you revise it to the below, it will be fully linear: int enc_read(void) { int ret_val = enc_count; enc_count = 0; return r

Nicely presented video. It looks like after drawing the first screen, it just doesn't respond at all! My initial hypothesis is that perhaps the touch screen is constantly reporting that a touch is hap

Great to hear! Thanks, Dennis! Reed

Over at https://groups.io/g/BITX20/topic/ubitx_v6_specifications/82557868 I saw some folks wondering how in the world something could be damaged by undervoltage, since as we all know, when things are

Hi Pierre, Updating the code in the spot mentioned will alert you when you go out of band (however you define it), but won't prevent you from transmitting out of band. It shouldn't be too difficult to

Hi Jerry, I just realized the manual wasn't linked in the readme.md in the code, so I've added that link now (thanks for the nudge, Jim S). For your reference: https://docs.google.com/document/d/1jlll
