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).

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)?

Note that 0dB = 1V/Pa. If you look at some of the specs of other elements, they have typical sensitivities from ~ -40 to -30dB. There is a huge range....

Re: Different Tuning Steps #ubitx

 

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.

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.??

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.?

Re: Basic board test: 130ma @ 12.5 volts #ubitx

 

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.

Not stupid.

It's not in the instructions.
Also, the photo clearly shows no Raduino plugged in.
? ??
Seems Farhan wrote that 7 months ago, and this has all since slipped his mind.

There's nothing?that would be damaged if a uBitx main board were powered up
without a Raduino plugged in.??

Looking at the Raduino connector on the uBitx main board schematic near the bottom of this webpage:
? ??
there are signals for??T/R, TXA,TXB,TXC,?CLK0,CLK1,CLK2, CW-KEY, and CW-TONE.


The relay driver at Q15 for T/R won't have any current going into the base,
so that transistor won't be on.? The rig will not be trying to transmit.

Likewise for the LPF band-switching relays at TXA,TXB,TXC.
Though if some of them were on we don't really care.

Perfectly fine that the three clocks are dead, that won't hurt anything.

CW-KEY won't be unbalancing the first mixer because there's no current going in there.
Doesn't really matter anyways because T/R does not have us in transmit mode.

CW-TONE is fine if there's no current going in.?
And would be fine if 5v was applied there anyways.

You might think we could have damage if T/R was somehow injecting current
into Q15, which would power up the transmit amp with inappropriate LPF filters selected by the relays.
However, with all clocks dead, won't have any RF energy going out anyway.
And if there was RF, the IRF510's powered at 12v would be fine (at least for awhile) with the high SWR.

I'd recommend you follow the WireUp instructions as originally written up.
Follow the example in the photo, and do not plug in the Raduino.
I don't see anything wrong with that.
If it were a problem, then we would probably have lots of failures when
blowing new firmware with the rig powered on, no reports of such failures.

I'm much more concerned with the false sense of protection from reversed supply leads?
provided by the recommended reverse diode and no inline fuse, that's a recipe for disaster.
We have several threads on this, search for "reverse polarity" here:??/g/BITX20/messages

Jerry, KE7ER?

If if this is an important caution, why not just say..."plug in raduino then do test". ?Why leave us to guess and be stupid??

So so I was stupid.?

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.

Hello Derek,

I firstly fitted the normal lcd display so the hole was cut for that the 2.4 screen just covers the hole I am mounting mine on the front panel with small standoffs.I am also running a version 3 with KD8CEC 1.07 and have today worked most of Europe on 40 mtrs with my dipole.regards dave g0ayd

Hi Dave and others using the Nextion display.

Nice to know all is running well.

However, did you do anything about the 3mm inactive strip along the RHS or did you mount the screen with a slightly smaller cut-out to the screen size? Perhaps you have not bothered about this at all?
I take it you got everything up and running using the supplied display first. I have the 2.8 and 3.2 displays available here.
Any issues with transferring the firmware?
Any tips would be welcome.

Re: Different Tuning Steps #ubitx

Jack Purdum
 

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).
