Is this the same project as the OSH park board: https://oshpark.com/profiles/KV4QB ?

Just wanted to confirm that this is also the VU2ESE AGC and get the component layout.

Are you sure it isn't Rotary.h? The case matters and must match what you see in your Rotary library directory.

I'm reasonably familiar with hardware here - grew up with 'toobs' and kept pace through to Pentium level - but never got much beyond BASIC (and variants), so this Arduino stuff is spinning my head. I've managed to install the IDE on my Raspberry Pi, from the repository, but seem to have 'queered the pitch' on this my 'workhorse' Kubuntu machine by attempting installation by the tar.xz fiole. Oh, well, onward ... to open 1.8.2 sketch. Error: no rotary.h. OK, where from, and where to put it? Real noob stuff here ...



Re: New to programming

Keep in mind that C is case-sensitive. The header file for the rotary encoder is Rotary.h, so you would likely need something like:

#include <Rotary.h>        // The case for 'R' must match the file name

The brackets cause the compiler to look in your default directory (/Arduino/libraries/Rotary/) for the library file. If you use:

#include "MorseCode.h"

the compiler looks in the current working directory where the sketch is located. If it doesn't find it there, then it looks in the default directory. This way, you can dink around with a header file in your code without changing the "real" library. Always use double quotes when you have a header file for a specific project.

Sounds like you are using an old version of the Arduino IDE.

You can install the library manually.  The one here should work.  https://github.com/brianlow/Rotary

Follow the instructions in the readme.  The exact path for the library will be ~/Arduino/libraries/Rotary/rotary.h

Hope this helps.

Imagine the full charged lead acid battery  voltage reaches  to 13.5 or 13.8V.
I suppose that 13.xx is called for from that aspect.

Glad to hear that you are up and running with the new Bitx40.
My suspicion is that 13.8 v may have been too much for the previous
One. I have seen a few people suggest 13 v max, though I am not sure where that number comes from. It seems like maybe the display is fried on the old Raduino. Now that you have a working rig you might be able to use that to help diagnose the old one (ie you could try putting the old display on the new raduino). 

Best of luck and above all ... have fun!

Re: Starting Over

 

Curt,

I would suggest leave RV1 alone, just check the PA current with PTT pressed and no audio.
If it is very low then look at adjusting it.

Only adjust R136 for power output. If you still don't get enough then look at increasing MIC gain by adding a preamp.
Dynamic mic outputs are lower than electret condenser mics.

It seems like I'm going to have to adjust that a little with the meter in the PA circuit to get it to 1amp. Tomorrow night I'm going to swap out the SO-239 connector. The one that they provided with the case seems cheap and although the center conductor makes good contact, it wants to spin a little and that shouldn't happen.

Yes this is Farhan's setup with board layout from Duwayne. All info is in the post linked at the top.

 

I will have more boards in about 1 1/2 weeks or so and I will have to adjust the price as I shot myself in the foot on the last batch. 1.3$ board cost and 2.67$ shipping. Multiples will only cost 2.67 shipping.

Yea those are nice cases. They guy who makes them posted in here last month. Looks good in blue.

Even though I felt I did everything right with the first one it had me questioning that it could have been something that I did.  I'll just be glad when I get the connector swapped out and the PA adjusted so I can get it buttoned up and on the air.  

When I mounted the plastic cover over the display tonight I was surprised when I leaked off the protective coating to see that they laser etched BITX into the plastic. 

John, that case came from eBay and it ships from India. I think it was $34 including shipping. Maybe a little overpriced but I think it was worth the money. It looks like they are sold out of the blue ones but they still have red. Do a search for Universal Case Model Maroon 1 or Universal Case Model Maroon 1 with accessories. If you get the one with accessories it comes with some extra parts like the speaker and speaker mounting tabs. You'll have to read the contents of both but one is just the case, the other has accessories. Here's two more pics of mine. I really like the BITX etching.

Yes, I'll post some pictures tomorrow when I open it back up to install the new SO-239.

Re: Starting Over

I think that the 1 amp calibration is total power current, not just the PA power current.  There might not be much difference (and I could be wrong).

Hi Dexter,

You can install the rotary library from the library manager.  Follow the instructions here https://groups.io/g/BITX20/wiki/Installing-Arduino-Libraries but substitute rotary for the si5351 library.

The Arduino IDE is in the Ubuntu repositories so you should be able to do an apt-get install there too.

Where did you find that Case? That is very nice. All I can find are the Aluminum ones with square corners.
