There are two things being said, but let me hopefully make the distinction clear. The stock uBiTX does not have an AM receiving mode, that decodes AM signals "properly", using an amplitude detector. H

I described how to skip the BFO stage, but didn't put any thought into if it would actually work for AM. It may actually be that the audio mixing stage ended up becoming the BFO, sans filter, or perha

Hi Jeff, I would love to see my work get pulled into the main line, but I don't have any control over that. Ashhar certainly could do so at any time, but hasn't so far. He did pull a little from the C

You should be able to listen to AM even with the BFO. However, if you want to get rid of it completely for some reason, you'll need to jumper C211 to C40 to remove the BFO crystal filter stage, then m

That's an excellent point, Niels! Another issue I fixed in my build (and thus didn't think about), but the stock software does require the knob to be turned to force the sideband switch, and could eas

I suppose I should address the cal stuff too. The main oscillator cal calibrates the frequency generator, which determines how correct all three of the clock outputs from the chip are. The BFO cal adj

Hi Dan, If you're using the stock software, you should be able to press and hold (for a LONG time, like 10s) the button after powering the radio on, and it will go to a config menu. You can then chang

My software does that (among other changes). https://github.com/reedbn/ubitxv6 Reed

Hi Jeff, Are you saying that you can hear a SSB transmission using either side band mode? WWV is an AM signal, so it would make sense that you would be able to hear it on both side bands. I know that

Send hfsignals an email and they'll quote you for PayPal. I think it's around $60 shipped to the US. Reed

Bill: To my knowledge, none of my changes have made it back into the "official" code base. I created some pull requests early on, but they didn't go anywhere. Barry: Maybe, but as I mentioned in the o

Matt: I added a 4 channel favorites menu to my software version. I haven't done any explicit documentation - only explanations of stuff to people in threads on this forum - but I hope that operation s

Evan, You're on point. It really depends what you want out of your radio. Reed

Hi Urs, Getting both a bad nano and bad touch screen definitely made for a rocky start. I'm glad you're up and running now. TSW has a teensy 4.0 adapter, and there's also the JACKAL which has some ext

Hi Urs, If you're already replacing the screen with a Nextion, not sure if it's worth spending too much more time and money on getting the stock style one working :P Reed

#v6

Hi Urs, Those results definitely seem to be pointing towards an issue with the touch part of the touch screen. One more thing you can try: In the master branch, make the same change to remove the chec

I can also confirm that it looks like it's working now! No scary warnings :) Reed

I see GNDREF on T1, T2, T3, and T4 in the v6 schematic, but I went ahead and tested continuity on TP1, and sure enough, it conducts to GND at DC. Only paths are through caps (open at DC) and T2 induct

Hi Urs, Evan Hand kindly pointed out that the correct resistor value is just 125, not 125k. If you heard tones, it doesn't matter that much to be on the conservative side, but good to set the record s

Requires a very small amount of assembly. See https://www.hfsignals.com/index.php/ubitx-v6-assembling-the-full-kit/ Reed
