Re: Broke it like only a newbie can - Calibration problems

[email protected]
 

Aha, I missed that you already have the uBitx manager.? It really simplifies your calibration work.? You can put in a number like 131630 for master calibration and that should get you close (that's what my master calibration is set at).

Re: Broke it like only a newbie can - Calibration problems

Welcome to the world of fixing your own radio!? I had a very similar problem when I first loaded the CEC v1.122, I was confused by the calibration and BFO settings.? You probably lost your calibration when you loaded the new CEC firmware, so you need to recalibrate, and the calibration method is not the same as the stock firmware.??

Likewise your firmware load lost your BFO setting.? I also was confused by the default BFO setting of 11.997.000 in the CEC firmware.? That's just a default number, and it belongs with the older crystal filter (which was 12MHz).? Your v5 has the 11.059MHz crystals -- you can verify this by looking at the number on the cans, the ladder filter is the line of little oval shiny stainless steel crystals.? Put your 11.053.400 number in for BFO.

Good luck!

Brian,

I'd guess the Arduino Nano died.
Can you still upload new firmware to the Nano?
The good news is that they cost as little as 3 dollars, and are socketed on the Raduino to be easily replaced (since mid 2018).

Do you have a scope?
You might check to see if CLK2 into the DDS1 connector has a proper VFO signal, should be around 4.8mhz.
Alternately, listen for a 4.8mhz carrier on a nearby shortwave receiver.
(Could be off by a couple hundred khz, depends on the operating freq saved to EEPROM.)
If the 4.8mhz VFO is there, then the Nano is at least doing something.

The wiring harnesses on the Bitx40 have a bunch of wires flying around loose.
Some of those wires are quite dangerous, such as the loose wire from the Raduino that has 12v on it.
If the end of such a wire touches the wrong thing, it can destroy the Nano (or something else).
Best to either tape over the ends of those wires, or remove the wire from the connector
by pressing the retaining clip at the connector with a sharp tool while tugging lightly at the wire.

The Nano clones being so cheap, some simply fail due to poor quality control.
For example, some of the Nano's work, but draw 10x the supply current that they should.?
For a while.

The wiring instructions and diagrams that Allard provides
? ??
are pretty good.? I don't think I could describe that wiring any better.

Jerry, KE7ER

I gave that a try and it doesn't give me the option to reset it. It opens up with the "Set Tune Step" menu.

New Arrivals Universal Case for uBitx- Nextion

 

We have been providing the uBitx case for Nextion 2.4 Inch And 2.8 Displays as well as 3.5 Inch And 5 Inch Displays Case.
New arrivals are for 3.2 Inch Nextion Display and 4.3 Inch Display colors Texture Black, Light Green with Black faceplates. And Blue and White.
3.2 Inch Nextion Display and 4.3 Inch Display case are not listed on our website as yet due to clearing of back log orders.
If any one requires the case not listed can email us.

Hope friends who purchased the 3.5 Inch And 5 Inch Display case have had a good experience building uBitx in our case.

Thanks to all and best regards

Re: v5 Alive! (plus my advice, and thanks)

 

Here's another post from Raj, affirming that he was using a yellow S+M brand 1210 inductor.

Here, Raj says that TDK-EPCOS parts work as well? (EPCOS was bought out by TDK).

Farhan chose a different method of fixing spurs on the v5 uBitx,
primarily the low pass filter at L31, L32, C205 near the first mixer.
That filter removes the 90mhz second harmonic coming out of the 45mhz IF amp.
Other possibly significant changes on v5 with regard to spurs would be the BFR93W's
at Q20,21,22? (were MMBT3904's) and the move to 220 ohms at R26 (was 470).

No display on LCD (Does light when PTT is pressed), no? tuning clicks no receive audio other than a hiss.? It really was the last step before I found a case for the radio.? I ordered a new kit, but I don¡¯t know exactly what I did to break the device.? I do know that I wired the RX-TX WITHOUT the ptt button.? The straight key I wired to the raduino and then to the main ground.? I am not 100% sure If I did both of these mods at the same time or not.?
