Re: uBitX V6 only transmits double sideband

Niels Jalling
 

Hi Jeff

When shifting from LSB to USB or from USB to LSB you have to move the VFO frequency a little because just pressing the LSB or USB icons does not change the BFO frequency so when listening to a station you don't hear any change.

I don't know if this small error has been fixed in the latest version of the software.

Re: uBitX assembled: bit of a challenge with alignment/bfo adj - Volume/switch knob fix

I suppose I should address the cal stuff too.

The main oscillator cal calibrates the frequency generator, which determines how correct all three of the clock outputs from the chip are. The BFO cal adjusts the offset of the second stage, relative to the first, and thus determines where the 45MHz mix ends up relative to the much steeper 11MHz crystal filter. Usually, you'll want the 45MHz to mix down such that the side band of interest falls within the filter's pass band, and the carrier and other side band are not. It's possible to adjust the BFO backwards, so that LSB and USB are reversed. If this happens, you can "undo" it by re-adjusting the BFO cal to the "other" good spot (there should be two places where signal comes through).

If you're finding that you're a bit off of the cals, then I definitely suggest doing iterative tweaks. Tune to 10MHz (or a known AM station), then go into the main cal and tweak it a bit. After doing that, go back and adjust the BFO. Then re-adjust the main cal. Back and forth until you're happy. Note that you'll want to write down the cals each time, since the stock software reverts the cal when you enter the menu (side note: my software doesn't have this problem)

Re: uBitX assembled: bit of a challenge with alignment/bfo adj - Volume/switch knob fix

Hi Dan,

If you're using the stock software, you should be able to press and hold (for a LONG time, like 10s) the button after powering the radio on, and it will go to a config menu. You can then change the oscillator and BFO cals at will, without having to do the screen cal.

uBitX assembled: bit of a challenge with alignment/bfo adj - Volume/switch knob fix

Dan D'Eon
 

Hello. Got my full kit (board v6.2 / firmware v6.1) the other day and assembled it this morning.Easy as pie.

I managed to puzzle out (I think) how to get into alignment: hold tuning knob in while powering up. The screen calibrate _everytime_ is annoying. Zerobeating is challenging because there is a second hetrodyne that becomes audible and climbs in frequency *just* as I'm approaching zerobeat. So far, when I tune WWV afterwards, the display read 10,000.05, and I've done it a number of times. Setting the BFO - what's that about? I used an audio spectrum analyzer as 1 post suggested, but - is that all there is to it?

Volume/switch knob: I dealt with that by grinding down about 3/32" of the knob from the radio side of the knob. This allows that setscrew to move further down the switch shaft and it gets much better purchase on the shaft.It just doesn't have the same flare now as the tuning knob.

Please ring in with suggestions.

Thanks and 73

Thanks! That’s a great price!
Hows the ripple on that one Stephen?

Right now I have a small 12volt storage battery hook up. 
Good pure DC. I charge it with a small 110 car charger.

Anyone know if there is a software mod to highlight the band currently selected?

It is poor user operability if touching a button shows no action on that button.

Re: uBitX V6 only transmits double sideband

Thank you Reed. That is helpful.
This seems like a pitfall that should have been documented or warned against if the rig is improperly adjusted.
On if I listed to WWV on USB and LSB:
No, I did mean that actual SSB ham signals tune exactly the same if setting is USB or LSB.

Hi Jeff,

Are you saying that you can hear a SSB transmission using either side band mode? WWV is an AM signal, so it would make sense that you would be able to hear it on both side bands.

I know that I could tune my BFO in some weird ways to get cross-sideband outputs. Perhaps try adjusting your BFO either higher or lower than what sounds nice? I found that I had to make mine a bit tinny to keep the carrier and opposite side band suppressed.

Evan,
I ordered and just received the microphone with pre-amplifier that you suggested I buy. I also built a poor-man’s low power watt meter. To compare the new microphone with the original Baofeng microphone, I downloaded a signal generator app on my iPhone 6 and set it to 70% volume on a 1,000 hertz tone. I then measured the power output at the antenna connector by putting the iPhone next to the microphone being tested and moved the iPhone on the microphone until I got the maximum output. I repeated this test at a frequency on each of the bands. There was 10 fold increase on the 80 and 40 meter bands! In my opinion, if someone plans to order a uBITX v6.1 for voice use, they might as well order a microphone with a pre-amplifier at the same time and save themselves a lot of grief. Evan, thank you very much for pointing me in the right direction. Sincerely, Stephen P. S. Now, I have to do some serious searching on the posts to find the most efficient antenna for use on the 40 meter band.

I’m confused about how/where to find specific uBitX  V6  setup instructions.

Jeeze, I could write up more accurate assemble directions myself. I know that the uBitX kits are low cost but clear directions would save a whole lot of  frustration and repeat questions and improve the view of these kits. Its documentation QC is lacking.

Most likely I have at least one thing setup
the wrong way.

On hardware or software installed:
No other hardware installed, no software. Its just as it came in the mail.
It always ( for the 15 hours i've had it operating) has receive tuned both sidebands one  unintelligible but as audible in sound as the other,   and  I assume has been transmitting on both sidebands. 
Thanks again for responding.
I’ve written HF Sigs to ask questions, give feedback....... they should hear it also.

Carrier imbalance and/or unbalanced mixer/modulator could be problems.
Improper BFO versus carrier settings can cause this problem.  Try redoing 
the frequency alignment steps.  

How are you determining that it is DSB and not SSB?  When you tune your 
uBITX V6 across a weak carrier, can you hear carrier on both sides of 
zero-beat, or just on one side?

What hardware mods have you installed?
What software mods have you installed?
Did it ever work properly?
When did the problem occur?

Hi,
Anyone have insight as to why my uBitX V6 only transmits double sideband ?
Also only receiving both sidebands I beleive.
It seems to work ok otherwise.
If It defective I want to send it back.
Thanks

Re: uBitX V6 only transmits double sideband

Jeff Debes
 

Thanks everyone for the suggestions: 

So I followed the Ashar Farhan  alignment video as best I could and I can tune in WWV at 10 mhz precisely zero beating the signal.
I’m not at a place where I have access to a PC.
On sideband, in  tuning an upper or lower SSB signal, the receive switching either USB or LSB makes no difference, both tune the same I can copy well on either. That does not  seem  right.
Any thoughts or suggestions? 

I read all remarks and I do realize this is a very low cost radio, yet I am disappointed that documentation is not better. If it were, this forum would have fewer questions to answer.

I own a KX3 Elecraft and enjoy that , but  this rig is a far cry from the quality or ease of use of that much more complex radio, yet the KX3 kit assembly was precise, clear, and worked first time.  Likewise every Small Wonder Labs kit I‘ve  built has been fine even with much more complex assembly or tuning  involved.

There is quite a bit of documentation available.  If you have trouble 
understanding some of the more technical parts, just ask specifically 
about it here on this discussion group.  Many persons are available 
and willing to provide explanations, comments, bad info, and so on.

Re: #ubitxcw #ubitxv6 More signal out on 10 meters than other bands? #ubitxcw #ubitxv6

Stephen KO4CVU
 

Evan,
I ordered and just received the microphone with pre-amplifier that you suggested I buy. I also built a poor-man’s low power watt meter. To compare the new microphone with the original Baofeng microphone, I downloaded a signal generator app on my iPhone 6 and set it to 70% volume on a 1,000 hertz tone. I then measured the power output at the antenna connector by putting the iPhone next to the microphone being tested and moved the iPhone on the microphone until I got the maximum output. I repeated this test at a frequency on each of the bands. There was 10 fold increase on the 80 and 40 meter bands! In my opinion, if someone plans to order a uBITX v6.1 for voice use, they might as well order a microphone with a pre-amplifier at the same time and save themselves a lot of grief. Evan, thank you very much for pointing me in the right direction. Sincerely, Stephen P. S. Now, I have to do some serious searching on the posts to find the most efficient antenna for use on the 40 meter band.
