If only the small plug was right angle, it would be perfect for me. My encoder is about a inch away and the straight one would hit it. I have never found a right angle in that style of plug.

Hi Group.

A friend gave me a uBITX to get me back on the air. I have been inactive
for years, no make that decades. The uBITX is working, at least the
receiver portion. The only antenna I have at the moment is a wire in the
attic. I hope to get some friends to come out and put my inverted V back
up. I already know that I am interested in an AGC mod.

"...showing kids in our schools tech club that you don’t have to be rich to be a ham!"

Amen to that! I've told this story before (QST, March, 2016): Our club set up a GOTA station at the 2015 FD and had a 13 year old make some contacts. He was so excited, it was contagious! I heard him excitedly tell his mother about the contacts and her reply was: "I'm sure it's a wonderful hobby, but where are you going to get the thousands of dollars for the radio?"

It looked like she shot him.

That was the instant I decided to modify the Forty-9er (i.e., the QST article) so someone on a lawnmower budget could have a viable rig for under $50. Farhan has taken this philosophy far beyond that and made this hobby affordable to thousands of others. Kudos to Farhan, Hans, and all the other pioneers who make our hobby the greatest there is and more available than it would be otherwise...

If turning down the volume control decreases volume of the clicking then the
problem may be ahead of that point.  If turning down the volume control does
not decrease the clicking then the problem may be after the volume control. 

Since the problem goes away when the Raduino is unplugged it may be coming
from that unit, but not 100 percent sure of that.  Unplugging the Raduino kills
several signals to the BITX and thus clicking going away may be caused by
disabling something in the BITX itself.

At this point we probably need to know if this rig is a BITX-40 or a uBITX?  Next
troubleshooting steps will depend on which radio we are working with.

I've watched the video, and noted that ticking increasing in level at low volumes. I venture this is an instability similar to that sometimes present in the Bitx-40, solved by a resistor (1 to 10k) from Vol-wiper to IC 'in' pin. Now the TDA chip is 2 amplifiers, and it's likely both are unstable. Voltmeter pin 1 (AC range) or o'scope, and you'll likely see the 'blips'you hear, and then on pin 3 constant blips.
Cure: replace R75 with 2k2 or so (solving the high-level), and similar 2k2 pin7 to VOL-M and top of C78 (break that track) to solve the low-level...

Re: Building a uBITX

Hi George,

I have a bitx40 that I've been using since I built it up several months ago. I was more interested in getting it one the air than making it look pretty so is definitely a 'junkyard' rig. I've used for several RTTY contests, use it for FT8, or whatever floats my boat. The only modification was a nice 10-turn pot I bought for peanuts at a hamfest and flashed Allard's firmware. Been to busy with stuff on my workbench, e.g. a new ubitx, and family life to get on the air the last few weeks. It's a solid little transceiver.

Raj's response seems to be more on target, post 46601
Also Dexter's post about filtering the 12v power supply line to the Raduino.

This may be firmware issue but I doubt it.

The original firmware for the Bitx40 as shipped did not have a problem with tuning ticks.
About a year ago, the Etherkit library was changed to reset the si5351 PLL whenever the frequency changed,
and that definitely caused clicks when tuning.  If you happened to update firmware within the month or
so time period when the problematic Etherkit library was out, then yes you may have firmware
that is causing tuning clicks.  As of last summer, Allard's code no longer uses the Etherkit library.

Regardless, it's a very good idea to update your Bitx40 to Allard's latest firmware.
I'd recommend the v2 firmware, though it does require a few simple hardware mods
that Allard's v1 firmware does not need.   https://github.com/amunters/

You are hearing the LOOP refresh of the nano controlling the SI chip. What is strange is that you can hear it with the
volume control disconnected.

Try to add some capacitors to the audio amps power supply line and see. It should go away. The filter capacitor C110
may not be soldered properly or defective.

Apparently Allard's software is crucial to curing this problem.

Here's how to do it:

go to https://github.com/amunters/bitx40

click on green tab "Clone or download"

click on "Download ZIP"

save the file,  and unzip it

(CAN SOMEONE PLEASE PROVIDE COMPILE/LOADING INSTRUCTIONS FOR SERGIO??)


---break---

If Allard's software does not cure it completely, you might try making
the volume control wires shorter, and routing the volume control wires
away from other wires.

I do not have a BITX40 - I have a uBITX, so I cannot go through all the steps
to test this out. However, the above process should cure the problem.

Saluti,

I use mine nearly every day on the Badger Weather net, the morning
Kansas WX net, and the evening Kansas WX net. Sometimes the propagation
is so poor that I have to hook up the big rig but many times someone
can relay for me even if the net control can't hear me on the ubitx.

I can't wait to try ND6T's new agc arrangement to make the net
operating a little more hands off the volume knob. But that won't stop
me from using the rig. It's going to be a simple change - unplug the
old ckt board and plug in the new one, both the size of a postage stamp!

Re: Building a uBITX

Just my experience: You can make this rig whatever you want.  I built the Bitx40 and it worked fine so you could stop there and have a nice little rig.  And, this group is a good place to talk about operational issues.  Of course, some of us can't leave well enough alone.  So, it is is a great rig for those folks as well.  Inevitably, the latter group is going to smoke something or need some help and this group is an ideal place for that as well.  I agree with Jack, there likely are a lot of folks happily hamming along without a peep.
