If you use something like FLdigi to watch the modulation, which can graphically show you the frequency of the modulation, you can probably calibrate pretty accurately.

Using WWV or WWVH for frequency calibration is a bit confusing unless you know
about their modulation scheme.  They transmit carrier with 500 Hz modulation during
part of the even minutes and carrier with 600 Hz modulation during part of the odd
minutes.  Minutes 43 through 52 are un-modulated carrier.  These are the times when
Scroll down in the page for this URL and you will find a chart that explains all this.

Hi Al, 

I too was completely unsuccessful to calibrate against WWV.  I had multiple zero-beat points (not sure what they were due to) and I couldn't determine which was the correct one to use for zero-beat, and I ended up with opposite sidebands and other annoying oddities that I don't recall.  Perhaps these would have been avoided if I had just written the default BFO values; but I wasn't that smart then.  The first thing I would do, with a new radio is to update the factory firmware with Ian's firmware (http://www.hamskey.com/2018/01/how-to-upgrade-ubitx-firmware.html?q=xloader ) ; explicitly download the default configurations, and then go through the calibration steps that I have above. 

Here are some links to help you use uBITX_Manager. These were written a few releases ago so the details may be incorrect (baud rates) or new features not listed:

Note that the recent addition of the Reset ("Rest") button is very helpful as you won't have to plug/unplug your USB cable as you modify the settings.

Re: Protoneer Nano-Arm #ubitx

Gary Anderson
 

Also received my Protoneer  in the mail today with a 20 Apr order date. 
I just plugged it in and downloaded / installed the Arduino SAMD board version 1.6.18, running in Arduino 1.8.5
Using the blink demo, I changed to a fast blink rate and confirmed the basics work.

When I get some time, I will first try getting the SlowSoftI2C  working on something.  I have a ADS1115 ADC board.

Of the various versions of Raduino code out there, what do the interested parties think should be the first code to get converted to the Arm M0?
I was thinking either the factory code as a test case or a released and non-Beta version of Ian's code.  I'm heavily leaning to Ian's code, since I think most  Arduino hackers will start with that.

Re: BITX for 10 meters

I think many would be interested in a 6m-2m-70cm version. Of course those transverters may work. But I have a 70cm of these transverter and never worked in TX. In the end I gave up and opted for a Kenwood ts-811.

If looking for a compressor, a search on eBay for SSM2167 will produce a few results.

The "Orange board" has been used  a few times and produces good results at around $5 each.

I increased the compression ratio to 4:1 by changing one resistor (instructions on eBay) and it really keeps the average power up.

Memory CW - Island Keyboard by WB9KZY

iz oos
 

Straight Key and paddle work. However I wanted something automatic like contest macros. In Linux I could not manage to send correct cw with the Ubitx. In windows was a bit better, not perfect (I was using the DTR port, I have not tried the RTS yet). Btw tonight I tried an old kit called 'Island Keyboard with the optional tube keying output' by WB9KZY and It works perfectly! It does work with an old keyboard not PC. It uses a solid state relay and I suspect this is the key for a neat cw, 73 Franco

Re: Calibration - my approach #ubitx

Al Woodhull
 

I had a horrible time trying to calibrate using the procedure in Rod's manual and KD8CEC version 1.072.  Part of the problem was that with current
ionospheric conditions WWV's 10 MHz signal has not been good in my locations at the times I have been free to work on this. And as I tried to zero beat
WWV my uBitX seemed to jump from USB to LSB or back.  That is of course what is supposed to happen in general use, although I didn't expect it to
happen during the calibration procedure.  I went back and reinstalled Ashhar's  original firmware, and was frustrated that I could not get the memory
manager to work. in looking for instructions on using the memory manager the instructions said that changes were needed to Ashhar's  source to
make the memory manager work. I decided that was not worth my time, I am a CW person and I think Ian's firmware works much better on CW

I am now thinking of going to get Ian's v1.073 and try again.  I am also considering modifying the source to change the frequency at which
USB/LSB change automatically to something slightly different, like 9.900 MHz. Does anyone else think that might be  worthwhile?

Also, I wonder if somewhere there is an up-to-date manual on using the memory manager with Ian's current firmware.

Re: ND6T AGC implementation for uBIT-X

OK, "the button has been pushed" and the Gerbers are sent. They still have to accept the Gerber files. Based on DHL shipping experience, the boards should be at my door in 10 working days. The average cost of the two boards plus DHL shipping works out to about $0.12 each. However, that means that they accept the Gerbers and that the boards are correct. I really don't need any more neat 100mm x 100mm coffee cup coasters.

The boards will still have to be cut (on my shear) or snapped apart before use. Now to see about getting some more bulk parts in here and see what the total price will be postpaid, getting some testing done, and figuring out inexpensive payment methods.  

Gary, KJ5VW, is still compiling a spreadsheet of those who expressed an interest and we'll probably post that in the files section soon.

We have plenty of boards coming for the first pass .....320 AGC boards and 280 Click filter boards. 

Looks like these guys WILL DO step and repeat at a reasonable cost so I don't have to do that manually again (bummer of an activity since the part ID's increment).
