Odd situation.
I have a working v4 in a metal case (from )
It has been working fine for a long time.
I had ordered a v5 months ago and finally decided to put it to work. I installed it in the same case the v4 was using, kept everything the same.
The v5 powers up fine, display great, output power fine (into a dummy load) but NO AUDIO.
The interesting thing is that if I remove the board from the metal chassis (just unscrew it and lift it a bit so the board does not touch the metal posts, the Audio come back!
Touch the chassis with one of the 4 holes in the board, NO AUDIO!!
Any suggestions? Is the v5 substantially different from the v5 that something in the periphery can affect it? (mic, key, earphone plugs, encoder/volume, power supply)
Regards and thanks,
A

Re: New uBITX Ver. 6 Assembled Today
just to throw my own experience in here, I was suspecting the mic was bad too, but I also didn't have a proper low power meter. This morning I found an old power meter with a 10W range and tested again. No power out on SSB. I also find the mic I used with my version 3, and I see about 4 Watts out with a hearty Hallooooo! Into the mic.?
I'll take it apart this weekend and see what's up, but I also have 2 of the Pacific Antenna qrpkits mics to assemble and I hear good things about those.? I'll report back.? Sent from my Burroughs B7700 - Neil Goldstein, W2NDG

Ashhar/Hans
hams everywhere are truly blessed to experience fine radios.? all was meant to try to 'redeem' a thread focusing on concerns with the size etc of the uBITX (one can wonder where the term micro comes from?) - so I merely invited him to consider the QSX.? I appreciate the correct path each of you has taken to benefit a vast number of ham ops.?
my v4 ubitx and QCX are doing well, ditto for the U3S.? (I hope to finally check how the v4 works with shielded inductors and an added xtal filter, but I may not have spur data for a while - but if the rig works decently I suspect it will be pretty good also with spurious).?
those unexpected features on the QSX are quite welcome.?
sometimes I get concerned that those of us in the West dominate the list - I have learned wonderful info from Raj and Sunil and others in India and other places.? please everyone, enjoy your building and radiations.? belated happy 2020,

BUT, can you do things like add a new modulation scheme, like FreeDV or other codecs?
It seems that would require SDR-level coding, something that couldn't be easily bolted on at the UI level.
Would there be a codec "plug-in" interface?

This is not correct. The QSX user interface CAN be changed. Everything about the user interface is configurable. Display layout, operation of knobs and buttons, etc. You could also build your own totally different front-end hardware and interface it.?
Writing your own code for QSX totally would be very difficult; and the only way would be to physically remove the microcontroller and put in a new blank one, then do all your programming from scratch; someone who is capable of that would be capable of rolling their own entirely (hardware and software) and I would be surprised to hear of anyone actually doing this.?
The QSX does include its own programming language which controls the UI and many other features, and can be modified by the owner. It is powerful and flexible and allows a lot of extensions to the QSX. It makes the QSX very hackable, both in terms of hardware and software. At the same time it shields the owner from the most complex parts of the code, and protects the IP.?

Re: New uBITX Ver. 6 Assembled Today
A good SWR meter can be got from Ebay for not very much. I have never owned an antenna analyzer - a SWR meter works just fine for a lot less.
Hi. I tested mine using another radio. Short length of just coax from the recivibg one. Then proper antenna on the other. Transmit abs as the receiving test, radio has little antenna it only gets a week signal but still enough to prove it is transmiting.?
If that test OK, get a friend to give you a shout and work from there.?
Vaughn
I¡¯ve been testing my new v6 it seems to receive well I¡¯ve heard several stations. Unfortunately I don¡¯t have an HF SWR meter to test with. I now suspect I¡¯m not transmitting. I tried listening (using a WebSDR site) to my own transmission ?but I hear nothing. Anyone have any suggestions?

Re: Need to Calibrate the V6
#v6
Thanks Ashhar, that got it done although I had to find WWV on 5mhz since the 10mhz just wasn't strong here.?
Some thoughts:
Would it be possible/reasonable for you to store the BFO and Freq adjustment numbers in EEPROM?? I had to go back and forth from setup to regular operation to finally get the v6 accurately at zero beat and each time the BFO and Freq adjustment numbers would revert to their defaults and I was starting from scratch again.? Also, the tuning speed could be damped down a bit; it seems far too jumpy right now....

Re: Need to Calibrate the V6

I experience similar difficulties with settings and freqs shifting during the button press. But too many miles for me to get a ham/electronic hobbyists candy store as it were hihi.? Only one here was a morphed Radio Shack (aka TheSource) and since Bell Globemedia took it over all the hobbyist candy inventory has been removed; now they just flog cell phones TV's and Express Vu Sat TV. selection for us is really gone downhill.

This is exactly why, when I assembled my v5 uBITX, I didn't use the push shiwtch on the encoder, but instead connected a separate red SPST push switch on the front panel of the radio. Works like a charm with no interference to or from the encoder.

If you just need to load a hex, avrdude from the command prompt
should work too:
That assumes you have avrdude installed and are comfortable
running command line prompts, though. No GUI.

Dope. Read Andy's stuff but not the initial prompt. I don't have any suggestions beyond xloader for Windows and using the Arduino IDE or avrdude for anything else

Re: Loading HEX to Nano

You might try Xloader if the PC's or laptops are running windoze
OS's; no equivalent for linux flavors I have found yet.
I just put arduino IDE into a linux box and tried to get a hex
file imported into it but no go. I did a quick compile / export
sketch, similar code to what is in the Utube video link below, to
duplicate the resetting of the ubitx nano using an android phone
USB link because, as Reed and others have pointed out the way the
nano is mounted the reset button is not readily accessible or
visible so the arduinodroid seemed like a good option.
also need a Micro USB Male to Mini USB Female Data Sync &
Charge Adapter Cable to connect nano to phone
One would be well advised to do all your familiarization with
the arduino IDE without the nano in the uBITx connected as the IDE
has some features that do a couple of things in a sequence and
then upload your practse sketches. I use the export sketches
options to obtain compilations and hex files to study or work
with. Maybe invest in one of the cheap arduino uno boards or kits
to do experimenting.
Here are a few

more vid tutorials NOOBIES might want to go through first before
embarking on blind mouseclikkin' fingerpokin :
I had received a hex file from Reed and hence I am trying to find
a work around to upload it from my linux box. I spent a few hours
watching video tutorials so haven't yet got a good solution for
using my linux box to do this; I have a nice large (32") bright
display on it to be able to code in arduino sketches with ease
rather than tiny little dim laptop screens on battery.
It looks like one needs all three files as shown in att pic to be
able to view the actual sketch code in the arduino IDE window; and
the the two hex files to upload directly ( one with and one
without the bootloader) an .ino and 2 .hex files.

I know about AvrDude and USBtiny and similar methods of getting
HEX into the Nano and that's fine for us semi-technical types.?
What I have been looking for and unable to find is any super
simple system that will use the USB connection and simple software
to program the Nano rather than requiring the Nano to be pulled
out of the radio so that it can be used with a burner like
USBtiny. Setting up the Arduino IDE is beyond some of the people
I'm trying to help so I'm looking for a way for others to load a
HEX file without pulling the Nano out of the radio.?
Many thanks in advance for any suggestions you may have...

I find it very helpful to hold the dial still with one hand and push the dial in with the other.
That said, the first time I encountered the setup was by starting the radio up while holding the encoder in.
That forces a screen recalibrate (use the stylus and be precise), and then it goes into the frequency setting (defaults to 10 MHz, I don't know if that can be changed easily, but I was able to zero-beat to WWV on 10 MHz), then on to the BFO setting (use the audio spectrum analyzer found here:??-- for the life of me, I can't find it anywhere on the various BitX V6 web pages -- Ashar PLEASE put a link on the V6 pages to the BFO tuning aid).
The trick to using the BFO tuning aid is to use the Chrome browsers and enabled access to your laptop/tablet microphone.? ?You will then see the tuning aid appear on the page.? Turn up the volume on the V6 on a blank area of the band, and adjust the BFO tuning until the noise is centered between the red lines on the audio spectrum display on your laptop/tablet.? The red lines signify 300 Hz and 3 kHz, which should be the pass band of the crystal filter in the V6.
Hope that helps,
73,
