Hrm, doesn't sound quite like my bitx40. I get the same static, and the same clicks from tuning, but not the ubiquitous clicks when not touching anything.

Have you opened it up and verified that the antenna connection is solid straight to the board?

Here are two troubleshooting videos I've used.

Re: Sweeperino?

 

It looks like you don't have the file si5351.ino in the same directory as the actual antonio sketch. I assume that when you first tried to compile the sketch, the Arduino IDE told you that the sketch needs to be in a folder with a certain name, and whether you want it to create that folder. That takes care of the correct folder structure, and it will move the main INO file into that folder, but it will not move the si5351.ino file, so you will have to move that manually, and after that, things should compile - still with a few warnings, but the compiler and linker will finish without any errors.?

Re: Upgrades and backward compatibility

 

Hi Gordon,

Just curious ... why do you prefer the V3 to the V4?

Re: suggestions for a graphics display

 

Thanks Tom, but it's too complicated for me!
What bothers me is that the bitx40 has been bought by everyone and everyone works with flying cables, YouTube is full of videos! My no!


 

I tried with a dipole set for 40m and a piece of wire, but nothing changes! What antenna is connected or not does not change!


Re: suggestions for a graphics display

 

Sounds like a great idea.

Have you thought of using the?ATSAMD processors?

I'd been looking at processors for an IoT project. Was amazed that the?ATSAMD processors, in many cases, cost less than the ATmega 8 bit processors. When you consider that many of these chips have built in USB support, eliminating the cost of the extra USB chip, that really helps the total cost.?

Maybe you could do a?Raduino board with a surface mount?ATSAMD directly on the board with the pins necessary to drive the display.?

It is also great these processors are supported with the familiar Arduino IDE and libraries. I still love the little Nano boards, though.

Tom, wb6b


 

Can you tell us a little more about your station? What antenna is being used with the BitX40? It actually sounds normal, but as if no antenna was connected.

=Vic=


 

Good morning This bitx40 has never worked! You can see from the video, just noise! I found a bitx40 card in a used market and I tried to replace it but nothing changed! He receives nothing except noise! I think then that the problem is the DDS VFO! I measured with a frequency meter the frequency that comes out of the VFO DDS not connected and from 34 Mhz, if I measure it when it is connected by 20 Mhz. Can you tell me where to connect the frequency meter to see how often it is receiving?
Or do you have any suggestions?
Thank you
Sergio


Re: suggestions for a graphics display

 

? Great Idea to go for graphics display. Let me congratulate the concept.?
if Diamonds are for ever, the display could also be? forever.

The hobbyist might change the rig , he can use his display on? NEW? rig also, and for any other T&M as and when developed.

WE may perhaps keep in mind a display that would be current for next 3 to 4 years.

peeps,

i am thinking of a graphics display for the bitx radios. here is the shopping list of ideas:
1, Ubiquitous : We should be able to source it from multiple sources and multiple countries with ease.
2. Low cost: The bitx40 costs 50 dollars to make. We can't tie it to a display alone that costs $20s.
3. RF friendly: Many of these display are very noisy.
4. Current consumption. We should be able to handle this with a few milliamps.

I have tried two options :
A) 128x64 LCD display. The common one uses the KS0108 display that needs about 11 pins. Which means, we will have to dedicate one ATMEGA328P as a 'display controller' that runs over a TTL serial line. That way, a single TTL line can be used to control the display. I have, at the moment, a display of this sort running where you can give send text message like "text 20,30, Hello world" or "rect 10,10,100,50". It seems to be a reasonable solution. It can even display the waterfall. The current consumotion is about 10 ma without the backlight. A 2N7000 turns the backlight on and off.
B) E-ink display. I have used modules from waveshare. The display is to die for. It does everything, costs a little more, however, alas, the display update time is lagging. You turn the knob and wait for the frequency to update. I haven't given up on it yet, I hope there is some breakthrough and we can get the frequency updated in real-time. If the frequency can be updated, then even the S meter would work.?

Any further ideas?

Re: SMD inductors for L5 and L7 replacement

 

Yes but, I found the smallest lead on the components in that area
picks up too much of harmonics from the relays. The high gain from
45MHz filter till finals plays havoc creating spurs.

If you want a shielded 680nF inductor, why not wind a few turns on a small yellow core ?

Re: PTT and Menus

 

Too many folk seem to recommend different firmware up front. I prefer getting to know the rig with stock firmware. I have made over a hundred qsos with it, yes I will try kd8cec some day.

With no button pushes, rig should go into transmit with ptt.

Press a button to go into menus. Use main tuning to scroll through them. Another press takes you into the visible function. The ptt will not transmit until you exit the menu selection.?

Yes its easy to not get mic correct. Try a piece of wire to locate the pins for ptt.

Be patient and enjoy the journey. Give me same advice when I post any issue I have.

Curt


Re: PTT and Menus

 

The short answer to your question on operating manual is no, not that I have found.? The one other point to remember is that any of the calibration inputs do not go into effect until you power cycle the Raduino/uBitx. That and the fact that you get an additional set of menus when you go into calibration mode.? I have been caught thinking that there was something wrong when I discovered that I had not power cycled or not switched back to the normal menu mode.

I gave up pretty quickly on the stock v4.3 code and 16x2 display for the KD8CEC software and Nextion color 2.4" display.? Because of that, I do not have any of the stock stuff implemented at this time, though I did keep the nano and display just in case.

If you have the funds, and in general are pleased with the radio, then I would suggest that upgrade, or the JackAl upgrade.? I have first hand experience with the KD8CEC software, and really like the full functionality that includes a way to manage the rig calibration and feature set.? I know that I would not go back to the original code.

If my? memory serves me correctly, the version should show up during the boot sequence, or may be on the screen in the lower right.? Otherwise, it is printed on the board.

One lower cost upgrade is to add another momentary push button to work in parallel with the button on the tuning encoder.? It can be a hassle to not turn the encoder at the same time that you press knob in.? ?That is a less than optimum solution in my experience.

Over all I like the rig, and have learned a lot from this group in trying to understand the signal purity issues.? That feature will not be available for the people that buy the v5 boards.

Though you may choose a different construction technique, if you make or buy a pcb keep in mind that the component placement silkscreen shown in the article is in error.? See attached.

Thanks!
I'll give it a try.
I like how simple it is.
The single section cap and untapped coil, both grounded, make construction easier than most.
Just wondered if that compromised performance.

I got a couple MPF102's that I first used in a project about 50 years ago.

Jerry,

I built that GDO? (see photo on post /g/BITX20/message/65252) ??but modified it to use a varactor diode with a 10 turn pot instead of the air variable.? Haven’t built any others so can’t comment on how it performs relative to other designs.? Also I’ve only wound the one coil to date so I don’t know how well it performs at higher frequencies with the varactor in place of the air variable. Iit works well on the range I selected (~2 to 7 MHz).? The component placement shown in the article has all of the transistors shown upside down.? A board is available from Far Circuits for $4.50.?

Re: Winding toroids

 

A good oscillator will dip.? the DIp is the response to power transfer.

As to the FET, a J310 will work as would a MPF102 or most any.

its just not that critical.? IF a 6C4 (low mu and low gain) oscillates
most anything will. Also a 6C4 is producing a lot more RF power
in a Eico710 (an easy .1W).

The key is the oscillator coils size and ability for it to couple to the
desired circuit.
