I have my basic ubitx working nicely, i just wish the cw filtering was a bit (lot) better. What is the best way to improve the cw filtering and narrow it down. Dave c

Hi Albert, You are way ahead of me. I too am trying to assemble the kit with the 3.5" Nextion display and the kit is full of mysteries. I can't find the exact code for the 3.5" display. The

Easiest is to add an audio filter of some sort between the phone jack on your uBitx and your headphones. For most of us, easiest means best. Strong adjacent signals will cause audio distortion, for

Thanjs Dave. I use v5 and Recollect some old comments about the 40m LPF inductor actial values vs sch indicated values.

I too have the case assembly with fan,audio amp and agc boards for the Nextion 3.5" screen.The supplied fan is noisy mechanically and electrically inducing noise on receive audio.Fan ran too fast so

Nothing beats the jackal board.

I will try that. Thanks!

I replaced mine with a 10mm Noctua fan, but I have the taller case. I don't recall hearing any noise. I also put it on a switch. But if you look at ubitx.net and search for fan, you will see where

Hi Albert, I put my fan in series with a 104 degree F thermal switch so it never comes on unless I talk for a real long time. There is no need to have it running all the time. BTW, I've only had the

I found the 3.5" TFT at the amateurradiokits website. You have to go to "My Account" dropdown (Orange Button) Depending on the login state you may have to login. There you will find a "downloads"

I've seen a few that had the wrong parts (inductors were obvious) installed for the 40M filter. Allison

Albert! I took the 2.3 inch from another listing an rewrote it for the 3.5. Not quite right. Found it and downloaded it and I'm about to try your suggestion, "ubitx_35_basic.tft." Let you know.

Thanks Allison. I measured 40m band LPF inductors were almost measuring 0.9nH and I haddepended on the accuracy of sch and reduced turns. regards vu3zmv

Albert! OK, that works. I don't like it as much as the ones that are smaller, but it does work. Looks like I have a lot to learn here. Thanks for helping me get started. Wayne

Mine do exactly the same. Filtering with ferrite beads etc, no luck. It may be a great improvement on the case, but another problem on the kit. Still love it, just set mine aside for a later time.

Hi all I am trying to compile the uBITX v5.1 code and i am getting compilation errors. I managed to sort out all except one... the error I get is: exit status 1

Hello, the arduino nano in my newly installed uBITX V5.1 is unreacheble from the program uBITX_Manager_V1.11. I wanted to install uBITX_CEC_V1.200, but alas, as rookie I can't get it

First you have to use Xloader software to programm the Arduino nano with the CEC hex file you need. You can find it on the hamskey.com website. I am now on the wrong place to inform you better. It

Thanks Raj for the great hint! I feel lucky I haven't waited 40 years for Antuino. It's really cleverly designed!!!

I don't mind a single post informing us of something of importance to us all. What I mind the 15 - 20 posts arguing about who is more righteous than thou. That, I consider spam.
