for some reason, wordpress wasn't updating the image. it ws something to do with folder permissions. i have updated the wiring diagram. that's done. as far as the CW is concerned, it is a software fix. i will hopefully push something out in this week as the 'standard upgrade'. on the hfsignals.com, we cannot recommend other software as i havent used them myself. what i am instead, doing is, to integrate the changes into the main trunk, test it out and them make them the shipped firmware as well as the one my own repo of github. more soon...

Ed and all,
I have not received my kit yet, though soon as I ordered January 19th, so I know it may be shipped soon. 

As a noob to kit building this forum is giving me lots of info to think about when the time comes. It has been years since I built anything, Heathkits in the day. 

My main focus will be to assemble it properly and get it on the air!!  And get  it into a case. 

Then maybe mods....
So again thanks to all for your info and comments.

Guys & Gals,
I didn't want to leave anyone out. I just thought I should remind everyone that this is a forum for the BitX (all BitX's). It is made up with thousands of radio amateurs who want to expand and enjoy their hobby. I have been licensed for 64 years now. I am a Technician (not an Engineer). I fix things, build them, troubleshoot them, analyze them, I read schematics, what I don't do is design things! Farhan has done an excellent job with the BitX and has made many improvements to his designs. He has put out a quality product that thousands have enjoyed using. Basically the BitX is a great entry level transceiver that is affordable for all. It is not a perfect transceiver, but that is what this forum is for, to share modifications, improvements, and new ideas with each other. We do have outstanding Engineers on this forum. No matter what your background is, there is help for you on this forum. If it doesn't work, someone will help you troubleshoot and find the answer. There is no warranty on the BitX. It is being offered that way to keep the costs down. I have one of the first uBitX's shipped. I put it together in a small chassis, I found a few mistakes and I fixed them. My output power with 12.6 volts applied is about 8 watts on 40 meteres. My first contact was 1500 miles away with a S9 report. I'm almost afraid to add any mods to it since it works sooo good. For beginners, when you get your uBitX, I have a few suggestions, First, follow the instructions, do not try to read the schematic, use the pictures in the instructions for placement of the colored wires. For the 3.5 mm speaker jack, do not jumper the tip to the ring, this will prevent shorting audio out when a mono plug is inserted. Last suggestion - It is a QRP transceiver, don't try to get more power out of it! If you need more power, use an external amplifier, there is a file on this forum on how to do this. Most power supplies run up to 13.8 volts, don't go over that, I chose 12.6 volts and nothing gets hot and I can use digital. Lastly, respect everyone on this group, we are from all over the world and we are all friends in our hobby.

Possible solution to the circuit protection problem.

I was looking through the Tayda Electronics website a bit ago and came across Polyswitch resettable fuses for $0.10 and $0.16 apiece in .5 amp (main board) and 3 amp (P/A) 30 volt resettable fuses.  Needless to say I added them to an order! If I remember Polyswitch info, they open pretty fast and take 30 seconds or so to reset.

The 3 amp 30 volt one is part# A-1458 and the .50 amp 30 volt one is part# A-1388

I plan to put them both on a small piece of perf-board and mount the board near the input connector.

And fast blow fuses.
Separate fuses for the main board (maybe 1/2 Amp) and finals (2 or 3 Amps).

Thank you Farhan Jee!  That looks really good - much easier to read than the multi-color diagram right out of KiCad.  Should help all of the newer people get it right.

Re: Complaint Department

Jerry Gaffke
 

That's very good news!

Though you might still consider an errata link at the top off to ubitx.net or similar,
along with some sort of disclaimer about how it's unofficial or whatever.
Then people won't be bugging you so much to keep it perfect.

Now that you've said you are cooking up new firmware, I'm sure you will be deluged
with suggestions, and of course need to ignore most of them.  But here's mine:

Look over posts 44278 and 44283. 

I'm thinking of having a "isCW" variable that can be set by the menu,
then use PTT as input for a straight key if isCW==1, remove the firmware keyer.
Much simpler, avoids that problematic analog read, I can use an external keyer
or the mike's PTT switch, frees up an analog input, and I don't switch between 
cw and ssb very often anyway.

Re: 13.8 v power supplies safe for bitx?

Tim Gorman
 

My 13.8v supply can only be adjusted down to 13v internally. So I added
a 10amp diode in series with the positive lead which takes the voltage
down to about 12.5v.

as previous post:

* used MPSH10's in all stages. 
* Used FT37-43 toroids all wound with 10 turns 0.25mm wire either
tri- or bi-filar according to original Sch.
* Bypassed all emitter resistors with a 220pF cap.
* swept from C80 input to T10 secondary (as wound)

Result is a very flat response. Better than 1db from 3Mhz to 54MHz.

Re: Complaint Department

Also from post 41737:

There has been one minor bug found since the si5351bx code was made available last summer, this line:
    i2cWrite(183, SI5351BX_XTALPF << 6);
should be changed to this:
    i2cWrite(183, (SI5351BX_XTALPF << 6) | 0x12);
to agree with the recommendations in the SiLabs apnote AN619
This may improve phase noise, though I have not heard any reports of it making any perceivable difference.

I have built 3 Bitx40 and 1 ubitx.  All of them are serviced with 13.84 volts - regulated and well filtered 5 amp power-supply.

I have run the bitx40 - on digital modes for many many hours and no issues.
Also the Ubitx has been performing very well.

Re: New file uploaded to BITX20@groups.io

Kai Nilakari
 

Hello,

This is a nice piece of s/w. I understand the limitations of Arduino Nano and try to get used to the single button user interface.
I 'd like to report a couple of bugs which I noticed the other day:

-Initial CW speed is at its maximum although I set it previously to, say 30 (wpm?). The display says 30 but the real speed is
way higher and I have to slow it down => I go to menu, adjust CW speed again. It stays there until I power off. Very annoying.
-The real CW speed value WPM is not what it says. To achieve 20 WPM one has to set it to double value.

Hi Ian.

Just updated to the new V1.051, all noted issues fixed.

Many thanks for all the good work you have done.

Kai,
Disregard the file V2.02R in my previous message  - there was still a bug in that one that got missed - the receiver offset on CW was set wrong and you would wind up twice the sidetone off frequency in the wrong direction.  I have fixed that now and the version attached to this message addresses both the keyer speed problem AND the wrong RX offset.

I deleted the bad message and am re-sending it again with the corrected software.

Apologies, and thank you for calling the bug to my attention.
