Typo correction:

Some Arduino Nano boards require the old bootloader the first time.
From the Arduino IDE, choose Processor > "ATmega328P (Old Bootloader)", and press the reset button on the Nano. The Arduino IDE will also load the new bootloader in EEPROM (XLoader and other tools may not do this).
Thereafter, the new bootloader should be in the Nano, and pressing reset should NOT be necessary.

Read about 1/3 of the way down, at https://www.arduino.cc/en/Guide/ArduinoNano

NOTE: We have updated the NANO board with a fresh bootloader. Boards sold from us from January 2018 have this new bootloader, while boards manufactured before that date have the old bootloader.

How should the port be configured?

They are configured as follows:

Data bits  8
Parity  None
Stop bits  1
Flow control  None
In Advance settings.... Use FIFO buffers is checked (requires 16550

The port was originally set at 9600 baud.... I set it for 115200
Neither setting works

Any ideas?

If it's working correctly, you won't see anything on the desktop or lower

have to hit the control panel, then Device Manager, and look at Ports (COM &
LPT).  (The image is from a Win 10 ultimate machine but it behaves the same
as my remaining Win 7 box.)

If the driver isn't loaded correctly, or there's a problem with a particular
USB port, you'll get an error pop-up in the lower right of the desktop when
you connect the Arduino.  Sometimes, using a different USB port is enough to
'force' Windows to reload/reconfigure the driver - that will usually make it
work in all USB ports.

Reed, 

I figured that,  when you sent the original message, but you maybe should have been a bit more specific as others might misinterpret it as working properly and not do anything about the actual problem.  

BTW I've had confirmation of the continuing TX offset problem from several other people since my original and subsequent posts on the subject and they are also using the (supposedly) latest V6.1 off github for testing.

I reiterate, it ain't fixed yet.

Kit ordeed but questions

Rick Tilton <rtilton@...>
 

First, THANKS for the add!  Maybe premature BUT my plan is to get the kit HOPEFULLY next week and get it working.  THEN I have question which is the best AGC circuit?   It appears 160m and 60m are doable.  Those with success and any directions?  I'm not a code writer but may have to study on it NOW!.  Has anyone written code to add more bands?  Is radio capable with current LPF's and all the other components? 

The v6 Nextion display conversion DEFINITELY has my eye but back to software.  Yes I know ONE STEP at a time. But am curious on these things.  

Also enticed by the work of I think John Lannigan and adding transverters, AM and such. DEFINITELY AM!  

Tnx & 73,

Re: uBITX V6 Sideband Issue

two points and then done:

1 - The dial frequency should always be the "carrier" frequency to insure you know where you are in the spectrum.  By carrier I mean that actual CW frequency sent, or where the carrier would be if the SSB signal was full AM. 
2 - If you don't like the way the radio works, change it!  That is the beauty of open source with open hardware,

Please excuse my rant, but just could not stand by.

Above are my opinions, yours can be different.

Windows 7 and Windows 10 will normally automatically install the CH340 driver the first time you connect the Nano or UNO to your PC.
If you have uninstalled driver with the remove files option, You can get the CH340 drivers at
https://cdn.sparkfun.com/assets/learn_tutorials/8/4/4/CH341SER.EXE
Instructions (read past the ads):
https://learn.sparkfun.com/tutorials/how-to-install-ch340-drivers/all

There is no need to uninstall the Arduino IDE to be able to use XLoader or other loaders.
In fact, you can use the AVRdude utility in the Arduino installation to load hex files:

Hello again,

I now have all the tools I need to update my uBITX V5 firmware to
KD8CEC's V1.2 firmware thanks to the help of this group.

My new problem is my computer(s). I am using Windows 7 Professional
service pack 1.

I want to use XLoader to upload hex files to my uBITX V5, however I
can't get the CH340 driver to install properly. No com ports are
recognized after installation (none show up in device manager). When
I install the CH340 driver it tells me that the driver has been
installed in advance, i.e. pre-installed. When I installed the
Arduino IDE it installed a bunch of drivers. I thought that might be
the problem so I removed it (using Revo Pro which removes everything
associated with the program).

I have also tried doing this on my Windows 7 Home premium computer
with the same result. Can anyone tell me what I am missing?

Thanks,

Thanks Dave.  Should I be able to detect the signal on KT1-3 pin 12 when keyed-up and talking?

Are there key points in the circuit I can test to narrow down the issue?   If something blew, what are the most likely offenders?

Re: Tuning knob behavior

AndyH
 

I'm somewhat surprised by the 'rig sliding' comments.  My µBITX is in a metal box with stick-on rubber feet, and I'm using a spinner knob with an inexpensive encoder.  I put four fingers on top of the case and my thumb falls on the tuning knob.  It's a one-hand operation throughout.  While I sometimes misjudge the length of press required to enter the step size function in Ian's software, making a step change is two button presses - one in and one out.  I would guess that a system requiring more button presses might provide more opportunity for sliding, especially with a lighter radio.  Can't say for sure, though, so that's just a guess.

I think my solution will be a NO push button on the front panel that advances the increment value by one digit (e.g., a 10x change) each time you press the button. After a user-defined number of presses, it "wraps" back to the starting position. I would probably start with the 10Hz digit and have 4 presses (e.g., 10KHz) before wrapping back to 10Hz... I think this approach for a frequency delta is better than an encoder switch press because my tests suggest it obviates the "rig sliding" problem which forces you to hold the rig with one hand as you press the encoder switch with the other.

Do you have commits you haven't pushed yet? My reading of the code suggests that CW tuning does not behave as Jim described.

Let's suppose somebody I want to chat with is transmitting exactly at 7.200.000Hz. Let's also suppose that I have my side tone set to 600Hz, and that I can tune perfectly to this pitch. Finally, suppose that I'm in LSB mode.

I tune my dial, and when my display says 7.200.000Hz then I will actually be hearing that frequency as 600Hz, because the actual tuning frequency is offset by the side tone, which is good
https://github.com/afarhan/ubitxv6/blob/master/ubitx_v6.1_code.ino#L391

However, when I then try and transmit, I believe that I end up transmitting at 7.199.400Hz, because the side tone is applied on transmit too

Re: low output only on 40m

Vic WA4THR
 

I have been following this thread with a little confusion, and I am not sure what the resolution is or if there is one. I have a V4 uBitX and the 40m CW output has always been low. Where I see 3.5w out on 40m CW into a dummy load, I can see 12w when on SSB and "Ahhh"ing into the microphone. I see a similar disparity on 17m. Since the SSB output is reasonable, I haven't worried about it too much and assumed something about the way CW is generated isn't unbalancing the mixer enough or something. Is there a fix?

FWIW, i am using KD8CEC v 1.1 software.
