Thanks, I just ordered two sets (10) from the ebay US site for $2.66. Doesn't make sense to roll your own. Dale -- Dale Hardin Elberta, AL

Hi, I have an unbuilt complete version 4 for sale.Mini stroke stops me starting this.?75.00 plus post. Contact me off group daveg0ayd@... willing post anywhere as long as you pay the postage

Hi Gary Yes sorry the regulator backwards, my bad eye's and late at night I missed that, all fixed and the new version uploaded. Why use an additional regulator.? It's the backlight that draws most

Dale I did this as a quickie using the 5 for 99c or so Chinese premade modules, like these.

I too created a fork, not with Smitty's additions, but one that uses PlatformIO instead of the Arduino IDE. You can check out the code here: https://github.com/th0ma5w/ubitxv6/tree/pio_pdq_gfx_update

To answer your request for the voltage measurements, You can use the v4 values for the SSB transmit side, as there are only minor differences.? The audio receive and bandpass filters are the

I would start with a BFO calibration.? The BFO will affect both receive AND SSB transmit, as the 11.092 MHz crystal filter and BFO need to be aligned in both directions. The best way that I have

Hi Thomas, The schematic can be found here: http://www.hfsignals.com/wp-content/uploads/2019/02/ubitx_v5.pdf. It lists all of the test points etc, so you should be able to find all the points worth

CW output appears to be fine. The mic and its connection is not the problem. The info I need is a table of of test point voltages with the radio settings appropriate to measuring them. I have seen

David, what IC is used in the schematic? I have a few of those TFT displays that will need the level shifter. Thanks, Dale

Dan, I’m getting inconsistent results on the receive side as well. Sometimes it works, sometimes not. I wonder if there is a code path that latches The A7 port - to zero during transmit, high during

Some of these displays dont play well with the onboard 3.3v regulator. Bypassing it and using an external 3.3v regulator eliminates any potential problems there. Regards Brian_____MM0BEF

Thanks Gary, David has fixed the error. Some of these displays dont play well with the onboard 3.3 regulator. Bypassing it and using an external 3.3v regulator eliminates any potential problems there.

David, Looks like you have the L78L33 regulator wired incorrectly in the schematic.? You want Vin from 5V Raduino to generate 3.3V for the LV side of the level shifter. Why supply the display module

And thanks from David G8DJM. Regards Brian_____MM0BEF

Thanks for suggestion. Im going to use the logic level shifter suggested by David G8DJM with a 3.3v regulator. I tried 1k in series with the data lines but that was not good enough so i was going to

Dont know how i missed that. Thanks Terry. Regards Brian_____MM0BEF

Re the schematic, the 3.3v regulator is shown wired backwards. -- https://www.vk5tm.com

Thanks again for this david. This should fix most of our problems. Great work. Best Regards Brian_____MMOBEF _______________________________________ David's original message: David S 9:29pm Hi all.?

Excelent work and much appreciated. Been really struggling with this on a V5 and this will fix it. Thanks again Best Regards Brian_____MM0BEF
