Hello John, Thanks for your reply,i own a home made radio which has full qsk and a dream to use it was produced by 2 uk amatuers in 1983 and is called the OMEGA,theres a picture of

I wish my life was so perfect that an off-topic thread would be enough to disturb me. Also, this thread probably would have only had about 3 posts if not for:

It's in receive mode only, and somehow coming from the main board. It is also volume-dependent - the louder the volume, the louder the 'ringing' (actually sounding a bit like an echo

I don't know if my previous post on this topic showed or not (I didn't see it being sent out from the server nor were there any replies)... but if I hadn't seen your original post, I would

I purchased a Nextion 3.5" cabinet kit from amateurradiokits DOT in. The case came quite complete with all the cables/connectors, etc. but a little lacking in assembly instructions. (I am a kit

I'm fine with letting conversations wander where they will, so long as folks remain civil. A good way to learn more about other forum members. Though admittedly, that EFHW thread did get kind of long

Hello Sama, I have done only adding the resistors on the cw line no other mods have been done ON .Dave G0AYD.

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
