Re: uBITX v4 with 7" Nextion Screen Issue #ubitx-help #nextion #1.097 #1.1 #nextion #ubitx-help

Again, JackAl does use either a 5" or a 7" touch screen display, but it is not one that is produced by Nextion. Nextion uses a different controller chip, which also means the libraries are different. The displays we use are distributed by buydisplay.com and our BOM supplies the part numbers for the displays, plus the options that needed by the display. Simply stated, the Nextion display will not work with the JackAl board.

Than also purchased JackAl bd to add as read 5 or 7 screen will work, Now told no only a TFT 7 inch no Nextion?
I am total confused?

HELP So I purchased  wrong screen? and What do I get?

Resistors finally arrived today, yaaaay.  Going to get one soldered up this evening and see how it goes.  Decided to go with 2.2 Ohms, wiring in 2 in parallel to get the 1.1 Ohm load.
I've also bolted a nice spare heatsink I had to the voltage rectifier, so fingers crossed that should do the trick.

I've done it like this so that if it doesn't work, it's a simple job of removing one of the resistors to up it to 2.2 Ohms.

Re: Q11,Q31 change

So ...Just because I could, I changed Q11 and Q31 to PNP types (2n3906) R11,31 to 10K R14,34 to 150 ohms ...

MDS (minimum detectable signal) by ear ~ 0.2 v P-P at VOL-H now is 0.1 uV ...  listening to 'noon-time-net' sounds ok

Lots 'o good signals

Maybe not state o the art or accepted general practice , but I'm pretty much ok with that

For the 7", it should read 7" resistive, the instructions are incorrect.

Re: Need a replacement Raduino.

Billy Shepherd <dis60cd@...>
 

Well good news. Was modding my bitx40 to remove "clicks" and shorted out the Raduino....so started looking for new one. However, I added a 2amp fuse when I built it and the fuse blew!!! All fine now :)

Correct. See yellow box below which was changed from 5":

Hi Harvey,
I pulled the board and measured the gate voltage on the BS170.
With no RF signal it reads 3.2629v

Rich, in your AGC circuit what do you set Q1 gate voltage to with no signal? It should be fully on with no audio signal and turn off as detected audio is applied.

Thanks, now I know where to set the pot.

Re: Error in Ubitx Mic Amp circuit?

Gary Anderson
 

Hi Uwe,
I see that no one has replied to your question, so:
The schematic indicates that a polarized capacitor 'could' be used here. 'Could' meaning it would be O.K. with respect to the voltages on the nodes to use a polarized cap.
However, a non polarized capacitor can most certainly be used.  Use of polarized caps is primarily driven by the lower cost and physical size for the required voltage rating.
Regards,
Gary

JackAl Forum

Jack, W8TEE
 

All:

We have just formed the JackAl Group for those who may be interested. Because JackAl is an add-on board for the µBITX, we designed the board to be an experimenters' platform. While JackAl does use over 200K of flash memory, its processor (a Teensy 3.6) scoots along at 180MHz and leaves about 780K of flash and 230K of SRAM free for experimentation and you still have about a dozen I/O pins to experiment with, too. We are also using the PJRC companion audio board to augment the DSP that JackAl supports.

Those who may be interested should visit the site:
