Give it a try. It should work fine on 3.5. It just won't use the whole screen. -- Dennis WC8C

on the print I have for the V6, R37 and C32 from Q32 are reversed, typo ?

Jonas, I like the aluminum case, the 3-d printed one looks cool. Is the Makita powering the UBitX? I also have the N7DDC Tuner for the UBitX. I don't have it finished yet, I am making a case for it

For some reason, the XLoader kept telling me that the upload was a failure. Then I changed the comport to COM1 then switched it back to COM8 and it uploaded perfectly. I have the uBITX back together.

how much of AGC range are you getting out of the emitter degeneration arrangement? A different approach maybe to use a series diode. - f

Hi, Here the tuning section I wrote for the ubitx_v4.3_code.ino: if (s > 6) frequency += 1250l; else if (s > 2) frequency += 100l; else if (s > 0) frequency += 10l;

My solution to a slight noise problem was to use a small toroid and wrap the 4 nextion leads through it. I run a nextion 3.5 on my ubitx without additional regulator. Added in a heat sink to the

Gordon, Would you like to understand the function of each "KTx" relay, which selection each "KT" relay corresponds to? I also want to improve them. Congratulations on your changes. 73's Rubens py2pvb

Aaron , Instead of using AA batteries ( I presume you mean NiMH type) I would consider a few 18650 type Li-Ion cells which can be fitted into clamp holders (max 4 in 1 holder) You obviously would need

Check the polarity of the mic cartridge. One leg is connected to the case, that should be your ground connection

Gerard, Sorry, I forgot that the audio amp sections were different. I think the pop problem would not be solved with the C38 change. The way it was fixed was between the v3 and v4, where Q74 was

Thanks for the comments about my uBitX, Aaron. I used an Excelway case from Banggood as I had picked up a couple when they were on sale for $8 and had used one for my BitX40. I inverted the case so

The Nextion display will generate some noise, especially if the brightness is not on full bright. You might want to check that.

Evan, Here part of the schematic for reception and amplifier The amplifier is a little different from the V6 I changed the C38 to 220µ for POP, but reduce, not eliminate. For amplification, it lacks

Barry, You have done an exceptionally tidy job of drawing out that schematic. Trystan

vu33gwn, My first guess at your issue would be you have the wrong hex file loaded, or if you compiled from the source code that the #defaults are not set for the v5 (compatible with the v6). I would

Would love to have this for a Nextion 3.5

Hi, Trying to upgrade my uBitx v6 to a 3.5" Nextion display. 1. Got the latest build from https://github.com/phdlee/ubitx/releases/tag/v1.20 and updated the raduino. 2. Found a good build (I hope)

try a different mic element. They are less than a dollar. Have had failures with the components. -- 73 Dave ADOB Raduino bracket and Ham_Made_Keys
