Re: [uBITx V6] #V6 Query re USB 4 port expander implementation
#v6
This is what I use on a uBITx v5. Not powered Maxxter. Holding the usb soundcard connected directly to uBITx Mic and Speaker ports. Then usb cable to uBITx Raduino. At left RTL-SDR dongle connected to SDR signal at IF of the uBITx and into the laptop via usb.  -- PE3ES - F4VTQ - Erwin 73

OK, that figures.....? I'd thought that the AGC out pad was going to be strong enough, given it's level being much better than the vol. pot "Hi" level. Given a range of incoming signals, I'm getting? .090v to 1.1v DC out from the AGC s-meter solder pad.? No prob, I'll add the amp to the vol. Hi as directed.?

Re: New Teensy 4.0 to NANO direct plug in adapter
#ubitx
#v6
Good news gang,? I've found an easy way to keep from having to make ANY hardware mods to the Factory V6 Raduino.? When I mentioned that you have to protect the Teensy 4 from the +5V on the A6 input pin by removing R2 (the keyer pullup resistor) and cutting the line from A6 to the KEYER pin on the right angle plug to the main board, I'm sure that turned many of you off, not wanting to modify your Factory Raduino by cutting traces.
I am kicking myself now as I forgot there are more I/O pins available on the Teensy then ever were on a NANO.? We have not implemented all of these, but it so happens that there are 2 of those extra inputs that ARE brought out to pads on the adapter board, the A8 and A9 inputs.?
The simple solution is, when building our adapter, simply leave out (or cut off) the pin that plugs into the A6 input on the Raduino's NANO socket.? This eliminates any possibility of the Keyer line causing any problems.? Since the keyer does not work reliably with 3.3V applied to the Teensy's A6 input and a different Keyer routine had to be used with a separate Paddle Jack, there is no reason that the extra paddle jack can't be connected to the A8 for dot and A9 for dash (or the other way around) paddle connections with a separate 3.5mm stereo jack used for paddle input.? The hand key stays on the PTT A3 input where it is in the first place, no changes needed there.?
It's an extremely simple software change in our software to use those inputs rather than A6 and A7.? That way A7 can remain a spare as it is on the factory Raduino and NO repeat NO hardware mods are needed to the V6 Raduino.? I'll post a revised construction manual for the Adapter kit later this morning and all future kits will be supplied with a 3 pin, right angle header to go in the extra pads.? Right angle is needed to keep it from interfering with the Teensy's USB connector which is used for programming and CAT control.

First of all let me wish all members of this wonderful group a happy new year 2020.
We have some remaining enclosures for Sale which are bitx40 and ubitx for version 3,4,5.
There are some standard case case with 1602 display and Nextion Display cases in all sizes for different Nextion Displays. Also individual faceplate for 2.4 inch and 2.8 inch display for standard case are available .
We may not be manufacturing the enclosures so if your kit is without a case it would be good idea to go for one.
We are working on our New Kit for Bitx which will be announced very soon.
My sincere thanks to all friends world wide who have provided us with a great importunity by purchasing our enclosures
and other kits.

Not too many, but maybe per product (BITx/uBITx/versions ?) and divided if needed for hardware and software

Update! I believe I figured out a fix to the white screen at not issue, committed to my pdq_gfx_update branch, f1ea1fd081d128895f336d0ca16de6246a422f2f.
The reason for not coming up appears to have nothing to do with power and everything to do with the initialization sequence in the drivers. It seems that my screen starts up in deep sleep mode sometimes, so by sending the right sequence to wake it up before initializing the driver, everything works as desired, no matter how many times I power cycle.
Thanks to everybody who chimed in here. I really appreciate you taking the time to help a stranger like me :)

Re: [BITxV6] BRICKED recovery help needed
Hey Andy,
I hope you got a good night's rest. I think I have a fix! The attached hex file for me has NOT white screened EVER in my testing. Prior to this commit (f1ea1fd081d128895f336d0ca16de6246a422f2f) I'd get a successful screen render once every blue moon. Now, I have yet to get a failed screen boot. Hopefully it solves the problem on your end too.

Added commit f1ea1fd081d128895f336d0ca16de6246a422f2f to this branch, which fixes the white screen startup issue for me.

Hi Andy,
I'm not sure what specific zip file you're referring to, but it
may be that the zip file just has the source code, and you would
have to use the Arduino IDE in order to compile and load it onto
your nano.
I've attached a .hex file that I just built from my pdq_gfx_update
branch. Maybe you can load it?

Re: [BITxV6] BRICKED recovery help needed
No I followed the instructions I gleaned from the group posts and
the scant mfr's documentation and was kind of learning as I went.
It was working at the end of the evening when I powered it down so
I could go to bed for the night. I turned it on the next morning
to continue familiarizing myself but when power was applied it
simply came up a blank white screen with no signal or RF white
noise coming from the speaker. I powered it down and restarted it
holding the TUNE button at the same time but everything just
stayed white and blank so it would not enter the initial start
setup routines either.
When I first received it, the initial setup of the ref freq would
not adjust to exactly 10 MHz but instead had to settle on 10.5
MHz; the Zero Beat Freq adjustment also did not set up as it was
supposed to; I had to ballpark it at 11.055 MHz then rock the
tuning control above and below until I could hear a reasonable
audio sound quality of RF white noise rather than a clearly
defined zero beat on a signal. In general the transceiver
functions were seemingly working but the audio sound quality has
always been tinny /water barrel like/ or Donald Ducky sounding. I
was able to receive the Canadian time signal on 3330 KHz but the
audio was not crisp and clear. I was unable to get into the
software to adjust or check software parameter settings; partly
because I had not progressed that far before it failed and partly
because Nobody answered in any group posts with links , tutorials
or comments about specifically running those manager type
programs.
In addition to being an advanced amateur, I am a retired
Electronics Engineering Technologist (35 yrs) with certification
in the Pace electronic repair course; so I know enough not to go
poking around in a willy nilly fashion.
cheers & 73 de VE4PER

As I understand it, the uBitx worked fine when it arrived.
You did some stuff and now it does not.

Good luck with that.

message on the upload there is just no display. With no
detailed tech info on programs or processes of diagnostic
nature or configuration software to run from the laptop the
only logical conclusion is that the display itself is what is
defective It appears.
If I was familiar and experienced enough to be able to run
some sort of other program modules like settings manager or
memory manager or any other types I might be better able to
come up with better half-split diagnosis. Like if I could load
up a program and run it in say something like a single step or
debug mode and get some feedback on statuses of what
components were working and what wasn't that would be helpful.
The only thing the Arduino GUI tool does is upload, which is
apparently working to get hex code into memory but no
associated GUI on the laptop to get any feedback.

The transistor will fry if there is a strong signal on the input.
If you were to TX from your shack on a nearby antenna then Q13 will blow.
