Highlighting band selected
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.

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.

Aaron,
I can think of 2 ways to reduce power when using digital modes.? The first reduces power for all modes via RV1.? That control can be adjusted to set the power for the rig.? The other choice is to reduce the audio drive to the uBiTx from the PC software.? This would allow full power when doing SSB, and reduced power when doing digital.
Digital does have a higher power level than the other modes, so reducing the audio drive would be a good thing.? Monitor the temperature of the finals and adjust accordingly.

Evan

Thank you for all of the great help.?
Is there a way to reduce the power for digital modes??
This rig is supposed to run 8-10 watts and to me that is a lot of power for digital modes. Also are the digital modes hard on the finals??

Thanks for the reply Arv! Just got it assembled yesterday. I made an ECARS ?contact this morning and the operator said that I was transmitting a double sideband signal. 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
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.?? 8-)
? This and below may not be about version-6, but still
an interesting read.

Jeff,
Watch this YouTube video. From the designer of the uBitxv6.

Re: uBitX V6 only transmits double sideband
Jeff,
Other than shipping, missing parts, or physical damage, all support for the uBiTx products is on this message board.? All are volunteers, so I would suggest that you take that into consideration.? This keeps the overhead costs down for HFSignals, and the price of the rig.? There are thousands of years of radio experience on this board.? A number did it as a profession.? Because it is via email like communication, it can take longer than a phone call, however, there is a high success rate on problem-solving with this process.
Here are two links that could help in the calibration and configuration of the v6:
First the directions from Ashhar Farhan one of the originators of HF Signals
Here is the BFO tuning aid that is discussed in the above video:
The above solves most of the problems that you describe.
