Re: Windows Serial Port Problem
Nigel G4ZAL
The uBitx uses a clone nano and the serial/USB chipset CH340.
In Windoze 10, open Device manager and right click the unusable/unwanted Parallel port LPT3 and delete it. Download the CH340 USB serial driver and run it. Plug in the ubitx and Windoze should install the correct driver. If it still doesn't work, maybe try editing the Windoze registry and remove all com ports... A reboot may help (it's Windoze after all). Nigel. |

Re: Mike element
I am now puzzled. Which gives more output? A mic with sensitivity - 24db or one at - 44db (as mine which still give some less output than the stock element)?

Try something under the maximum value 50000 should work and be almost as good as a fast way of getting around? i presume you ?know about Gen Coverage mode?? Go to band change and hold down the switch for a couple of secs.? It will then step up and down by a MHz on band change, which may also get you where you want to go?

I think Jack got it. The way Ian coded it you can't save that large of a value. It would probably be a good idea if there was some error checking in the uBitX Manager program where it wouldn't let you enter an invalid value. Or at least some warning about it.

Suggestion...to hop between WWV freqs, or any other freqs for that matter, put them in the channels...use the 'VFO to Channel' function in Ian's firmware. Then you can select which one you want using the 'Channel to VFO' function. I have the 5, 10, 15, & 20 MHz WWV freqs saved so I can check propagation. It's a lot faster than spinning the tuning knob.

Re: Different Tuning Steps

Or you could punt, and manually store the freqs for WWV in the memory channels available in the? KC8CEC 1.08 software ... I did that - it's arguably easier than dial twiddling, hi.? Sorry if this is no help - I know this doesn't address the coding issue and I haven't tried the step you're attempting.?? With arduinos though, I have had gnarly formatting issues displaying numbers on a tiny LCD display.?? You may have to mess with the LCD formatting code for the screens that are giving you display problems? to get a readable display. assuming the long int used? for arTuneStep and associated variables remain sane.? v/r pete? kh6dk On Sat, Jul 14, 2018 at 2:49 PM, Lee <mr.olson@...> wrote: Yes, it is KC8CEC 1.08.??

Re: Basic board test: 130ma @ 12.5 volts

Jerry - as the original "not stupid" guy, thank you VERY much for the detailed analysis of a mainboard w/o raduino. ?
This is kit has been so much fun to build. I've loved every minute of it.? The receiver and audio are really fine. I'm using an efficient clossed-back 5" midrange, and the CEC software. ?On a strong signal, the volume is "sweet" and ample. Nice to listen to. ?Weak signals & inefficient speaker could easily be a problem. But not here.? Amazingly the basic cat control (freq change) works great from WSJTX!! ?I jumped out of my seat when I clicked on a freq within WSJTX and the uBitx changes to that freq. ?How cool is that!!! ?And for us liberal arts majors, that means we figured out how to load up the required apps, get the configurations and ports and a thousand other technical details right, and not screw it up. A slap on the back for a non-EE. Hahahah. The transmit half is not working yet. ?I built the mic in a pill bottle in honor of the Dr. ?But, there is not enough audio modulation to make a signal. ?So I'm using the keyer generated tone, but even that gives me next to no RF output. ?So I have to keep working at that. ?I'll double check my work and see if I can stumble on the problem and careen into a fix. That normally my problem solving methodology.? More work to come, with crossed fingers. ?I can't tell you all how much I want to make a contact with a transceiver I build.? Thanks. |

Are you editing KD8CEC sketch?? If so, this won't achieve what you want.? These values are only the initial values when the programme first runs.? They won't apply once values have been saved in EEPROM. You can change the step values in UBitx Manager software in Windows (easiest method), or (I think) in the setup menu.

Re: Windows Serial Port Problem
Sometimes if you are not using a Profilic (probably spelled way wrong) original driver but a 3 rd party driver, you have to delete the driver and install the 3rd party driver.? This seems to happen to many almost? every time win 10 updates. This may explain it.

Windows Serial Port Problem
A few days ago my Windows 10 installation got updated, without asking me, of course.? I stepped away from the computer for a while and when
I came back updates were being installed. I think my USB port drivers were changed.? When I try to run the KD8CEC Memory Manager or to upload a newly compiled? ubitx_20 version I do not see the COM4 port any more. The Windows Device Manger shows an "Unusable Parallel Port (LPT3) where I previously saw a COM4 Serial Port. Does anyone know what happened or how to undo it? - Al N1AW |

A signed int on a Nano is a 2-byte number. Because the Most Significant Bit (MSB) is the sign bit, you only have 2^15 = 32,767 Anything after that sets the sign bit and appears as a negative number. I would guess that's what happened here, since it only happens on the largest value. Since you are working with frequencies, in Hertz, you should use the unsigned long data type. When you are assigning constant like below, it's good practice to use the data type specifier (in yellow below). Jack, w8TEE
