I have a brand-new, untouched uBITX version 5 for sale. Purchased May 2019, and I never found the time to do anything with it. $95 + shipping cost from Seattle Washington area to your location.

Thanks, mitch

Ashhar Oh My, I guess their will be be a LOT of Tea consumption in the coming Future for ALL to get the remaining 80% debugged.
I just ordered  a "kilo" of Green Jasmin ( the internet is just wonderful) thankful it is  Decaffeinated since unlike 30 years ago I cannot do 20 hours a day, any more.

I guess you can do your best in construction of the "kit" but a good study of the kit and all cabling is a MUST (I spent a good 2 hours in that task) to avoid placing them in the wrong areas I  learned that a long time ago when we had many more connectors and wire points then present times, and never mind the ones with kilo volts present .
Best Regards.

Description:
This data sheet appears to reflect the specs of the encoder that I received with my uBITX. It's the top encoder in the drawing. I used it to verify the wiring of my cable from the encoder PCB to the front panel PCB of my amateurradiokits 5" NEXTION cabinet.

Description:
This data sheet seems to match the encoder that I received with my uBITX. It was helpful in checking out the wiring to the rest of the circuitry. I couldn't find it on the files section so I hope I'm not duplicating. It's the one at the top of the drawings.

Re: RF power chain mods and improvements..

Herman,

Thank you for your enquiry.  The original mod comprised of swapping the pre-drivers and drivers for 2N2222's included cutting the original 20-ohm bias resistors in half.  Please confirm this with a forum search for 2N2222 modification.   

Forum user Allison mentioned the 2N5019 as a candidate for trial for this purpose, and I simply played a hunch that the resistor modification might apply with this semiconductor change as well as it did with the 2N2222 change.

Simply changing/altering the resistors and not swapping the original transistors will likely let out the magic smoke and release the socially-unacceptable words in a violent manner. 

73,

Re: uBITX v6 kit makes tones

You are correct. I had the plug, plugged into the audio connector on the mother board.

 

I connected it to the connector on the display board and it is working!!

 

Thanks,

Could you have the two cables interchanged? On the V5 it is the same plug.  Could you have the analog connector plugged in where the digital cable belongs?

Make sure your 8 pin connector is in the digital connector behind the
display not on the main board. Did that myself switch them and it worked
fine. Hope this help!

uBITX v6 kit makes tones

KENT HUFFORD <kq4kkham@...>
 

Just got a UBITX v6 kit pulled together. (no soldering)

 

Lights up main screen fine. Can change bands and modes by touch screen. Cannot change freqs by knob,

 

However, when I rotate the volume control it just changes a loud audio tone freq out the speaker.

 

When I rotate the freq knob, it sends a loud audio tone out the speaker about 20-30 times a turn.

 

Punch the tune knob, nothing changes.

 

I’ve built version 3, 4 and 5.1 kits. They all worked ok.

 

Ideas?

 

Thanks in advance

When you finally finish testing the code and release it, it is already 20% debugged.

Actually the 18, (should be 17) was at line 746, not 246 in the ubitx_ui.cpp file.  Bet you need more tea - LOL.

Thanks Ashhar,
I had just found the bug when your message arrived.  I have no problem compiling the code, thanks.  I'm also looking for a bug where the frequency is not saved after entering it with the freq keypad subscreen.  You can enter the frequency but it is never saved when you press OK.

Have a good holiday but I suspect you will be barraged with this on the group owing to all those who just received or will receive their V6's in the next few days (or maybe weeks if they ordered via India Post).

I'm sure it will all get sorted out eventually.

Peeps,
There is a bug in the ubitx_ui.cpp in line 246. It should read "17", instead it reads "18" in the code as shipped. This makes the button for 17 meters (18 Mhz) unusable, you have to use fast tune or direct frequency entry to get to 18 MHz. I have patched the source code on https://github.com/afarhan/ubitxv6
Remember, that the v6 source code compiles only when saved inside the sketches folder of the Arduino. This is an Arduino idiosyncracies.

Re: RF power chain mods and improvements..

Herman Scheper
 

Ted, I have one question about the V5 board:

 

I have here on stock the metal 2N2222A and also the 22 Ohm SMD . When I understand well you modified the V5 board with  ONLY  22 Ohm on top of the existing emitter bias resistor…

 

Tnx for reply,  Herman PA0BAB

Candidates I know of but not tested are: 
MPSH10 but I have to try them.
2n2222A  its worked in the past but the FT is barely enough.
2n3553//2n3866/2n5109 are likely good for driver (2 not four).


I've read some (bit not all 250+) of the posts in this thread, and I'd like to put in a plug for the 2N5109 as a viable upgrade for the pre-driver and driver stages.  The price is right for reputable sources, not so different from the more oft-recommended 2N2222's considering one only needs one of the former for each pair of the latter.

I swapped out my 3904's in the power chain on a V3 board some weeks ago and on a V5 board more recently adding a 22-ohm on top of the emitter bias resistor (because they were handy).  Power gains were impressive:  40 meter phone went from aroud 12W to 20W and 20 meter phone went from around 7W to around 25W or better  This is with a voice compression board installed, though that board went in first. If I over-drive it a little on digital such as JS8, it peaks around 30 but I don't see any point in compressing digital at all.  With a fan on the finals, digital outputs of around 15-20 watts keep the finals warm but not melting and there is plenty of spring left underneath the compression threshold [i.e. not compressing at all yet].  Output is far more stout than with the 3904's and VR1 is set lower than it was without the upgrade.

I'd recommend this as an easy course of action even if one intends to run low power levels, as it evens out the power for 30 & 20 meters & up.
