JS8Call has a new feature that is great for BITX owners: In the configuration, you can have it persist the PTT between 15 second frames. It'll save a lot of wear on your relays. It's not on by default, so you do have to configure it. It's under Rig > PTT.

Ill do it. Some stuff is taking up all my time for a couple of days more. I plan a fuller update of the website.

It would be nice to be able to see and print out an image of the µBitx V.5 component side silkscreen that shows the component locations. 

There are enough differences between the version to the point of where it is a bit tricky to find specific SMD components.

I put them to work today and came up with a nice set of hold down clamps for the BITeensio that mount using the front corner mounting holes on the main board and hook over the cable clearance notches on either side of the BITeensio.  I've updated the TSW website (www.w0eb.com) with all the details including pictures.

I will sell printed brackets, but only in the US (international shipping would be prohibitive due to necessary packaging) and that's only for the convenience of those who don't have a 3D printer or access to one through a friend. 

I've made the printable .stl file available on the website and attached it here for those who already have one of our BITeensio cards installed in their uBITX radio(s).  I'm also planning on posting the make on "Thingiverse" to make it accessible to everyone with a uBITX that wants a set. 

They only take about 40 minutes to print and if you use the print resolution and parameters included in the zip file they will be quite strong and easy to install.

​​Yes -- i've done the FT-817 bit for frequency control but always just did the signalink-type PTT.   I have not yet done any of the KD8CEC firmware.    


the easy digi should work FINE -- but it lacks the volume controls and I prefer a relay to the transistor for PTT.   My preferences, maybe not yours.   I bought one early on, but didn't think it would serve the needs of our group as well.   


PUT A CAPACIToR BETWEEN THE UBITX PTT LINE AND GrOuND -- like 0.01 uf.  


There are LOTS of ways to do digital, nothing says that my way is any better than others -- it is just what we've done for a few dozen systems locally.    


I havve been using the $4.75 Adafruit 1475 --- but there are probably much better choices out there for sound card...I just haven't studied it.    For the raspberry pi's that we have used these on, they need a "classless" sound dongle.


More power to you!

I look forward to digging into your manual and circuit.  I've been using an easy digi board.  If you use KD8CEC's firmware the µBITX can be CAT controlled as a FT-817 skipping the need for the PTT with the JT modes.

uBitx on JS8Call / FT8

Gordon Gibby
 

Homebrew sound-card isolator  matched to my uBitx today -- ran into unexpected problem:   begin transmission and instead of a solid TX, the push-to-talk chattered in and out of TX / RX / TX / RX about 5 times/second incessantly    


Sound card isolation system is a double transformer, gain pot, vox-type circuit with reed-relay output (https://qsl.net/nf4rc/2019/SmallBoxSoundCardInterfaceManual2.2.pdf and Gerbers are on github) -- so quite puzzled why this happening when never happens with ICOMS..... and the SIGNALINK worked perfectly!


After multiple false theories I finally recognized that the PTT line goes DIRECTLY into a Nano.   Adding a bypass capacitor or two from PTT line to ground (all I had on hand were .047's would have preferred .01) -- and problem solved!!!!   Completely new discovery for me with this design.


The uBitx requires WAY more audio than I'm used to with mic input of ICOmS --had to change the fixed resistor in the audio attenuator to allow 10dB higher signal.    Then it could be adjusted with the gain potentiometer.    


After all THAT, I got it up on JS8 and immediately got 2 answers to my HB signal both giving me reasonable SNR's, and their signals were fine also.    Wandered down to FT8 land....wall to wall signals.   I'll fiddle more with that another day.    


Great rig.   Has taught me a TON -- thanks to you folks!

Re: My first measurements with relay daughterboard

Now you have the proof you actually did an excellent job. I followed the easier (not so easy btw... ) route of replacing the relays with the Axicom but I believe you really made a better use of the LPFs.

I finally sat down to do some more work on my uBitx -- with the external relay daughterboard -- wired with just regular, unshielded wire.   I recall that I damaged and lost one section of one of the low pass filters (I think on 20 meters).


Here attached is the first plot I got attempting to look at the CW harmonics on 80/40/30 meters, using a 12V supply.   I had 67 dB of pads in line with the Siglent spectrum analyzer, and that entered as a correction factor.   Video and RBW were 30 kHz.   Frequencies are from 3-63 MHz so each major division is 6 MHz.   using "traces" with an averaging of 2, I was able to capture and hold traces of 80, 40 and 30 meter CW signals.   You can figure them out from the frequencies, but 

80 meters = purple

40 meters = yellow

30 meters = blue 


The blue horizontal line is my attempt to mark the FCC limit requirement for harmonics, 43 dB below an observed output of about 37 dBm.     


If I should make this measurement differently, I'm quite willing to hear improvements!  This was my first crack at it, and I've only had the spectrum analyzer for 2 months.   It has been used on MANY projects already.    


I believe you can see that the harmonics are WELL below the limit for these items tested.


I'll work at this some more and hopefully made more and better measurements.




Antuino! Look at your signal! Face the truth!
