Re: Ubitx V5 Low audio and No SSB #v5 #ubitx-help

Praba Karan,

If you used a different Nano to upgrade to the KD8CEC software, then you will need to recalibrate.  The calibration data from the factory is stored in the EEPROM, which is not saved/uploaded with the software.  Also, each board set is different, so you need to recalibrate anytime you change the Nano for a given board.

I would start with the BFO calibration to verify that it is correct.  I have used the following webpage with Chrome and a USB (or laptop) mic:
https://www.hfsignals.com/index.php/bfo-tuning-aid/

You want to adjust more towards the "high" side, as that reduces any carrier bleed through.  Note that the BFO should be close to 11.055500 MHz, as the SSB filter is 11.059 MHz.  For my board 11.055600 MHz was about right.

There is also the Memory Manager software from KD8CEC that I have found useful in being able to save the current settings prior to making changes, then to save again as I get closer to what I want.

Those Bafeong microphones are what I was thinking about when I mentioned opening the audio hole in the case.  They are notorious for having too small a hole or having the hole offset from the microphone position.  Some persons have even replaced the original Bafeong electret element with the larger electret that came with the uBITX.

Are you using the microphone cartridge that came with your uBITX V-5?
Several people have tried to use other microphones and experienced low 
audio level (low SSB output).  Some resolved the problem by enlarging 
the hole in the microphone housing to allow more audio to reach the 
electret cartridge.  

Your 7.8 volts bias to the microphone seems about right.

Also noted  during  just  pressing PTT, my swr/power meter displaying stable power output of 3 watts. 
I checked mic bias voltage, which is 7.8 volt.

Help me to identify root cause of these issues.

UBITx V4 Low audio output 80-40-20 #audiocircuit

I know this issue has been addressed many times, and I need some hardware, not theory to enjoy the fruits of my labor. My bench is a small desk with a VOM, and loads of hope to actually see what is necessary to work on electronic circuitry. No complaint with the audio output on the AM band, but gets dicey trying to listen to CW in the upper ether. Hearing is not all that good as before. Any ready built or kits that would beat the low audio output in the upper bands? Sure would appreciate it. Thank you. 73/KH2EE

uBITX Version 6 construction manual #ubitx #v6

Jim Sheldon
 

Since there have been a few posts on people having occasional troubles assembling the V6 "Full Kit" and for some reason they don't seem to be able to find the instructions (plain sight) on HF Signals website, I took the time to write up a fairly comprehensive construction manual for the V6 and did this while actually assembling the last one I bought.

I took photos during the process and tried to show the major points to help keep people out of trouble doing what should be a really straight-forward build.  I sent the PDF file to Ashhar Farhan who liked it and asked if they could print and include it with every kit they sold.  I gave him that permission but then the COVID 19 Virus hit and everyone is locked down.

Here is the PDF of that manual for anyone that needs it and I'm also going to upload it to the Files section of this group.

It will also be available on the TSW website, www.w0eb.com in the files section under "documentation" to make it fairly easy to find.  The manual is NOT copyrighted and may be freely reproduced/distributed but if you do, please leave it intact and submit any suggested changes or improvements to me (the author/photographer) via email direct (w0eb at cox dot net).

Thanks and I hope this helps clarify the build of this pretty decent kit.  Also, for the information of all, I have NO affiliation with HF Signals whatsoever, and I purchase the uBITX kit(s) just like everyone else at the full price on the website.

Re: Help with my ubitx v6 kit

McRuss
 

He did mention that it is the 'full kit'.  That being said, I'll bet it is the same problem that I had initially with my 'un-full' kit:  (I forget the terminology but) the wires from the control knob (as opposed to the on/off volume knob) plugged into the board rather than the arduino.  Just sayin'

Goodmorning..what kind of antenna do you use?? Are al the conectors on the board good and fitting???

Re: Receive Noise with USB #cat

Doug
 

Hi Erwin
Thanks for your reply. You are correct... I did change the monitor and that reduced the
noise somewhat..
The real problem was that the PCB board that had the female USB-b socket mounted on
it did not ground the shield of the socket.
When I found that, I ran a chassis ground to the shield and the receiver quieted with the usb
plugged in...
I think that will fix the problem..
Thanks for your response and help, Erwin.

What pc screen or laptop screen do you have Doug? These LCDs produce a lot of noise close to a receiver . Even when in stand by and also when plug is still in power outlet when switched off .
