On this forum (groups.io) it only shows the full e-mail if you have it setup to get the messages sent to your e-mail. If you have e-mail's set to "no email" then when you look at the post with a e-mail in it the info after the "@" will be missing.

 Hope that helps answer why it's like that.

I may be a dummy, but how do you send an email where after the @ is an elipsis to hide the
server?  I've asked the question several times on different forums.  Either no one knows or
"you just have to know".

I( guess I should have read all the posts you made before replying! Great that the external pull-up resistor worked, that was what I needed, too.

I just added the external pull up resistor to 5v without any other changes. It has worked fine ever since.

If you have a voltmeter, monitor the PTT line before you plug in the mic and after, and when you press the PTT switch That will show whether the line needs an external pull-up circuit. In my case, there was a little bit of a load when the mic was plugged in and that dropped the voltage with only the internal pull-up resistor enough to be right on the threshold of detecting a PTT signal, so I just added an external resistor from 5v to the PTT line and that kept the voltage up when not keying. Another solution is to go into the software sketch and change the voltage level at which it detects the PTT switch. This is a bit unique to the uBitX, since it detects the signal in the Arduino. The BitX40, where I use the same microphone, just keys a relay when the switch is pressed.

Actually, its moderated by the community and citations are required. Peer review is encouraged, and if issues arise they are solved. Just because it is open source doesn’t make it unreliable.

Besides they are alternate pneumonics, not exactly scholarly material.

As far as I know all of the Nanos use the miniUSB cable as apposed to the microUSB cable.  When ordering one just specify "miniUSB"

 Regarding the USB cable that fits the raduino, at least the earlier versions, I found it to be the same as the one that came switch my NIKON DSLR camera.
I bought a second cable on Ebay, that is the same.
 It is NOT the same as the ones found inmost stores. Those are a bit different, and fit most android cellphones,etc.
 I have a variety of those that I bought at the Dollar Tree.
 I don't know what the newer Raduino's take,only what the early version that most older Arduino NANO takes
 Some stores that sell NIKON and maybe some other cameras would have the cable,albeit, usually at a higher price.
 There is a big difference in the end that fits the NANO/Raduino compared to the more common type that fits most Androids.

Ron W2CTX sent me some documentation, I am set.   Please enjoy some time off! 

yes I just learned I need to add my callsign to my marker here - I guess indeed our email is invisible.

The tech support from the designer and seller are excellent.  But if they don't know, others building and using will find out.  Perhaps build it, use with an old PC, and later integrate the soundcard.

Attached is my calibration spreadsheet calculator, I use a free office app called Open Office.

It looks like it's gonna work,,,,will test it this week end....but maybe you can check it out and let me know if it's right?

I have a good comm receiver to measure my mbitx freq. output. My mbitx is transmitting 5 watts into a 50 ohm 15 watt dummy load. The comm RX has a 1 ft wire antenna with 40 db of attenuation cranked into it.

OK fer now CU all Later 73

What is your experience with drivers for this external card on Windows XP and/or 10?  Immediate integration of USB connectivity to the board seems like a good way to neaten up a final product and minimize connections to have to fiddle with in the field.

I'm not really faulting you for using a mnemonic that was a product of the times, but this is a case where litterally anything else would be just as good and "not politically correct" ends up meaning something more like "makes the hobby just that little bit less inclusive, for no benefit in particular".

Update: adding a 4.7k resister between the ptt pin and the 5v pin solced the problem for me.
