Jack, no, I don’t expect the same quality in the HFSigs as in my KX2.
( I said mistakenly KX3, but have the KX2)

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

How much was the microphone?

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.

Re: New uBITX v6 #ubitxv6 #signalink #ubitx

Evan Hand
 

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.

Re: New uBITX v6 #ubitxv6 #signalink #ubitx

Aaron K5ATG
 

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?

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?

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
https://www.youtube.com/watch?v=t6LGXhS4_O8
Here is the BFO tuning aid that is discussed in the above video:
https://www.hfsignals.com/index.php/bfo-tuning-aid/

The above solves most of the problems that you describe.

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.

Re: UK Import Charges

Ian Reeve
 

Yes that sounds about right I guess,a few years ago I had to pay the post office fee,some import duty on items over £100 or so then VAT.That was from America though if that made a difference.Never had a problem with DHL although on two occasions the parcels were opened at customs and resealed and arrived damaged.

I think the admin fee is £11, post office used to be £8, the rest is vat, I don' t think there is any import duty to pay.
DHL is a very fast delivery from anywhere in the world but it will cost you.
Very reliable service, you just have to work out all the costs to see if the item is worth it, would not hesitate to use DHL.

I've just paid the import charges invoice, and it came to £45 if anyone in interested, which is about what I was expecting.

Now I just need to wait for it to make it the last 10 miles or so.

Yes.  Straight simple cables connecting mic to speak, and ditto for speak to mic.

And +1 for Dean's observations.  

Or you can use the creators approach, just put your laptop near the rig, and they will hear each other. Hahaha.

I used a EASYDigi interface.  It has transformers for audio isolation, caps to block any DC, even a optical PPT circuit ( think signal link on the cheap). 

I felt great about my interface. Digital operations were reliable  and a blast.  Just one little issue: It made no difference whatsoever compared to jumper cables.  

Moral?  Simple is better, most always.  

My buddies with rig blasters,  signallinks, custom builds, have gone to great expense and complexity to put in a volume pot in the signal pathway. I figured how to set volume levels in the application and OS.  So no worries on the lost  extra level set knobs...hahah.

Go digital and get your comms on!

The one thing that I would add to Dean's advice is to include snap-on ferrites for the lines in and out of the computer (audio and USB).   I found I had RF feedback issues that distorted the audio in both directions, and some intermittent cat issues.  The ferrites seemed to solve that.

Also, I did need to purchase an inexpensive USB audio dongle for it to work with my laptop.  For that dongle, I connected the mono audio into both of the stereo input lines for the best results.  BTW, I have 3 and all seem to work with the WSJT-X software, so do not have a specific version to suggest.  I am currently using a Plugable adapter that is no longer available on Amazon where I bought it.

If you still have problems, then an  EasyDigi interface for the transformers will help in grounding issues.

Above are my experiences with both a v4 and v5 rig working FT8.
