Re: uBitX PTT cycling
That happened to me and I solved it through proper grounding and ferrit clamped over the coax going into the rig.? I used 2 of the clamp on type.? Need to get them that fit over the coax, or else an

Re: uBitX PTT cycling
Guy, what are you using for a power supply? If the voltage drops you might be getting that intermittent cycling you describe. If that is a v4 uBitX board, the audio output is very low as delivered. I

Re: uBitX PTT cycling
An update: Adding a pull-up 2.2K resistor between the 5v pin and the PTT line stopped the PTT cycling when the microphone was plugged in, so that is all working as expected, now. However, when

Re: started
I do have a couple of supplies that will do. One is a 2.5 or 3 amp adjustable. WE used it for servicing radios. And another is a 4 or 5 amp. I need to see if it is regulated or not. I can add

Re: low output only on 40m
Note: I have, like others, injected RF and manually swept the frequency through from 1 to 30 MHz. There is a horrible dip at the lower end i.e. 40 MHz is really low compared to 20 MHz. Yes I realize

Re: low output only on 40m
Same horrible problem! I have good output on all other bands - the best is 20 meters. However, the 40 meter band is really low! I have shelved this project (as this has dun my head in) for a while

Re: Recommended mods for spurs and harmonics
¡°the 12 mhz from the bfo leaks into the local oscillator. A 5uh in series with a 47 pf across C202 of the LPF will suppress it.¡± Is this a recommended mod?

Re: display not working
The nano would fit because the display is dead and the dds is not working. They also picked up an LCD. I fully believe that one of the two are bad. I'm excited to find out which. I started doing tech

Re: display not working
I suspect the nano soldering for no audio.

Re: display not working
I really think the nano has died. They are cheap anyway. Put an aftermarket firmware on it and swap the display if you get it first. Since you have no audio, Im betting the nano is dead. I could be

Re: display not working
Dan try removing the Raduino from the UBitx and powering it via the USB connector. If it boots up fine, then you could be having low supply voltage to your UBitx or just the Raduino via the main board
