Re: Ubitx versus other rigs
Now, let's make a field test. ?1 mile up you favorite dirt road (with chuck holes). Set up where there is a good tree to string a wire (your favorite kind). Set up radios, turn them on. Collins- won't work no AC, HW101 Won't work No AC uBitx works connected to car battery. ?Winner and still champion out in the field: uBitx!
?
That's kind of a fun comparison. Things have sure changed in radio. ?The uBitx is pretty darn affordable compared to any radio!

Hiro,
Switch off power to be safe. If some problem is there while programming then try unplugging the Raduino.
I have not had any problem with programming even with power on the board!

When I connect USB to the Raduino to rewrite the firmware, should I connect the Raduino to the uBITX main board or take the Raduino off from the main board?
And if the Raduino is connected to the main board, I suppose that I should turn off the main board anyway, right?
Thanks for your help.

Dear Dexter,
Thank you for your information,
the result did?nt change, there are only light shining display ore bold black signs, nolonger the frequenzies whne I trimm the blue pot
Kind regards

I went in holidays for two weeks, see You later :-))

Hallo Elmar,
Du meinst dieses board hier, das DU gewechselt hast :
Ich w¨¹rde mir das bestellen, wir fahren jetzt erstmal f¨¹r zwei Wochen in Urlaub, daher ruht das Projekt jetzt eine weile

Re: Troubleshooting decoder
Thanks for posting the part number.? I'm not even finished wiring mine and the encoder button has stuck in.? I'll wire a secondary button temporarily for bring-up, but it is nice to know where to get another encoder!

Re: Troubleshooting decoder
Ok. I had the same issue and replaced it with the part from Digi Key that I pasted to this note. It works great now. The encoders are fragile so I bought 5. I tested mine out of the unit with a continuity tester via DMM. The side with the three pin outs is what I used. Center is common or ground or whatever electronics guys call it today. So connect the meter to center and top pin and rotating should show short, open, short, open..... Do the same with respect to the bottom pin and same outcome. Mine was constant open on the bottom pin out. While your at it connect to the pins on the other side and it should act like a momentary switch.

I'm curious what you are using for an antenna or aerial.
I would tune to 7076 (in LSB) to listen for some tones called FT8 (decodable using WSJT-X software). Popular digital mode right now. You could tell if the Bitx40 was at least receiving. It's where most of the 40m activity is around me.
We were writing at the same time last night. I would definitely change the pot. I burned up one wiring the 5V to the wiper that way.
As some other have mentioned, a blue LCD with no writing or numbers may need the contrast pot adjusted. Also would need adjustment if the letters are white blocks or rectangles on blue.
I know I have to take a break for a week from time to time when I get stumped.
Best of luck to you Heinz.

Re: Basic board test: 130ma @ 12.5 volts
#ubitx
Do plug in the raduino and wire it up properly before measuring the current. You may even damage the board as many digital lines would be afloat. - f
Hello!! New uBitx V4 builder here.? Instructions call for a plain board power up with no connections beyond power Jack. So I have no plug in cables at all. No ardunio. Nada. zip attached.? With power 12.5v I get 130ma.? This is above specs of 80-100ma. Is the extra 30ma due to the extra half volt above 12? Or do I have a problem someplace? ? Thank you all VERY much.

Hi,
let's start the comparison by holding the price tags up next to one another:)

Greetings, Heinz!
There is a square blue preset potentiometer on the Raduino board. It adjusts the Contrast - the percentage of time the screen's characters are lit or dark. It is often left set? to 'lit' as new, but adjusting it cannot damage the Raduino ...
Hopefully helpfully,
Dex, ZL2DEX

I have been playing with electret mics and using one that has has -24 dB output. This is :
Note that 0dB = 1V/Pa. If you look at some of the specs of other elements, they have typical sensitivities from ~ -40 to -30dB. There is a huge range....

Guten Abend Heinz,
hatte aus Unachtsamkeit 12 Volt auf einen analog Port des kleinen nanoboards gebracht und diesen damit?
geschlachtet.
Da man den kompletten Baustein¡ªsoweit mir bekannt¡ªnicht mehr einzeln bekommt,
muss eine Reparatur versucht werden.
Das kleine nanoboard gibt es im Netz als Chinese clone f¨¹r etwa 3-4 Euro.
Nachdem mit gro?er Sorgfalt das Board gewechselt wurde muss die Software neu installiert werden?
(Raduino v.1.27.7).Es gibt im Netz eine step by step Anleitung daf¨¹r.
Anschliessend sollte man alle Verbindungen pr¨¹fen. In meinem Fall sind?leider drei Durchkontaktierungen
kaputt gegangen ?und das Display wurde nicht angesteuert.
Nach vielem hin und her l?uft das Ding nun wieder.
Bei weiteren Fragen ¡ªeinfach mailen
73, elmar

Hallo Elmar,
yep, in englisch tue ich mich echt schwer :-))
Er macht eindeutig Ger?usche, es h?rt sich aber nicht nach HF Signalen sondern eher nach
undefinierbarem L?rm an, wenigstens etwas.
Du hast das Board gewechselt ?
Also die gro?e Platine ?

PS ist es nun ein arduino oder ein raduino ? ich tue mich da echt schwer....

With the original
ADE-1,?pin 1,6 is?a coil, from where pin 5 is the center tap of the
2nd coil of the same transformer.
Same for pin 3,4
and?pin2.
?
Now, the ADE-1-24
has the following configuration.
pin 1,6 and pin 2
pin 3,4 and pin 5
?
Basically, ADE-1-24
pin 2 and 5?belong to the?other transformer with respect to the
ADE-1
?
If you connect the
ADE-1-24 as if it is the ADE-1, you will get other impedances / reflections /
suppressions / mixer losses.
Other that that,
it?might still work.
?

Hallo Heinz, denke ich kann in deutsch antworten? Hatte auch diese Problem. Erzeugt der Raduino noch ein vfo signal d.h. Der bitx funktioniert noch aber Das display zeigt nichts an ¡ªoder es ist alles still ?.? Durch Wechsel des nano boards und neue Software aufspielen, war mein arduino Zu reparieren. 73-Elmar dl2qa.

So here I am again with a brand new problem:
the raduino display only is lightend, but there is no more information.
What happend : I made any experience with the raduino and the power regulator, I connected
a PI Filter with 2 capacitors and on resistor 10 Ohms but only 1 Watt, the resistor crashed
and the power regulator 7805 on the raduino board crashes also.
So today I bought a new regualator and asked the specialist in the electronic shop how to connect it
and protect it. He sold me a new 7805, two ceramic capasistors of 100 nF, a diode and 1 resistor 10 Ohms
2 Watt.
I properly solderd all the parts correctly, but it is the same as after the crash, the display gets lightend
but shows no longer any information
What can I do, is there any way to get a new raduino ore how can I fix this problems
Kind regards Heinz Very beginner

Re: Soft for mBITX transceiver
Dear Barry thanks for warm words. I do have now Arduino 1.8.5 programm. But I do not have knowledge how to programm the arduino nano and what more I can't collect among the words the file with the sythesyzer 5351 programm - I mean simply take file and put it to loading programm. I see words and steps. + my English is not too good to catch all detales. Many thanks George.
