Our site was hacked last week and our ISP wasn't too concerned with our small site, but it is back up now. We need to restore our database again, but we're getting there.

I have found it interesting that toroids work when caps and coax don't work. Toroids are my go-to for rf noise.

I use these internally in radios A nextion display really benefits from them.

These on power cords and baluns.
and these around coax with PL259.

I bought 25 of each and thought that should last me a while. Ended up using almost all in 2 days. Shack noise when down a couple of S units. Wall worts have been particularly bad.

kevin -- I had the same problem with my 4.3 screen.? It is a bit of the wild west out there, so you just have to search, try and hope to find a TFT file that works for your screen. Sharpen your google search skills, and search like mad.? All of this is true because I wasn't willing to dive into nextion file editing and had no interest in rolling my own, so I had to depend on the good efforts of others.? So thank you all the "others" out there. You rock, as they say.?

For the 4.3, I finally found this file?unitx_43B7_pd5dj.tft? out there that worked perfectly.

I love the 4.3 screen size by the way.? It seems a great compromise for good readability and has enough screen room for my stupid fingers. haahah.

Glad all good with your build. Any idea why mine will not compliie? Using
the same sketch just keep getting the error message above.

Thanks for any help you can offer Vaugh

That worked for me using the old boot loader and yes the ten turn
removed
those annoying clicks. Now I find when getting close to the end of the
tuning range the frequency gallops.. did I read that the addition of a
component to each end of the pot cured this? I have also added the push
button to enter settings menu and extended the frequency range ...
1.28.1
certainly makes it much more useful... a worthy companion of my UBITX...
now I use that whilst continuing with my Jackal conversion..

Hi, been reading some of the topics here and yo are all very advanced
for my build. I am only just starting so need some help please, I hope
to
add some of your mods later.

I have a BITX40 and it has a ticking when I tune the frequency. I have
read that a fix is added by replacing the 1 turn pot with a 10 turn.
This
also needs changes to the sketch in the arduino.

I have downloaded the Arduino IDE and the new sketch, raduino_v1.28.1.
The problem I have is when compiling the sketch. I get the error ,

Not used: C:\Program
Files\WindowsApps\ArduinoLLC.ArduinoIDE_1.8.21.0_x86__mdqgnx93n4wtt\libraries\Adafruit_Circuit_Playground

exit status 1
redefinition of 'struct userparameters'

I think I have added all the required libraries but this will still
not
compile. I can see the problem is possibly in the name changes of
definitions, but this is as the sketch has been modified by so many
and not
rewritten. should still work but what have I missed?

any ideas please? I know you are all way ahead of my build, but until
I
complete this and so learn from this, I cannot start your mods or mods
of
my own. Please any help given will be most welcome.

Vaughn

Thanks Raj.?? I'll pick up some 51pF caps Monday.?? My local parts shop gets worried
if they haven't seen me in a day or two...

I'll try parts I have on hand first.?? Otherwise, it'll be time to put together another
Digikey order...?? I noticed I should have some Murata LQW2BASR33J00L unshielded
parts that I picked up for a Radioberry build.

This is the placement I'm planning, mostly because I'd already cut the trace from R27 to C10
in two places for the previous filter and this will cover the cuts.

I'll probably have to order some 30 uH parts.? 27 and 33 are easy to
get locally, 30 maybe not.

Sounds like the way to go, thanks.

John,

Very neat job on L5 and L7.

Make the 45MHz IF new filter with SMD parts. What seems to be the culprit
is any vertical wire leads in that area
causes trouble. Solder the SMDs directly on the board.

When I get back to town tomorrow I will try it.
