Re: how can download file x sbitx #sBitx

 

ok, i downloaded raspy imager, but when i go to write, it tells me that the sd is small. formatting it with windows gives me 29.1 gig and raspy says it needs 31.9. now I'm downloading the image file again, maybe I improve something. same thing also with balena hetcher .. wait? other info...

another? question :? the? file? imagine? need open or? i? write as is ??? tnx? to? all..?? i? hope? explicated? ok...? 73? in3izq danilo

Re: how can download file x sbitx #sBitx

 

You have to use a program that will create a bootable SD card. The Raspberry Pi Imager will work. Other popular programs that can be used include Rufus and Balena Etcher. All of those are available on Windows and other operating systems.

The card that came with your sBitx will work out of the box, and you can update the software in place with git. Reflashing the SD image is mostly useful if you lost the original card, damaged it somehow (either hardware or software), or you want to create an alternate card for testing forked software such as the builds from K3NG.

Re: Some calculations on the IF filter and USB filter

 

Mark,

The N8ME with VU3GAO mods does not have an issue with the v6 stock display.? Since the Nano updates the display, it should have a higher load than the KD8CEC software.? You could look at that code for ideas on implementing the encoder software.

Re: Some calculations on the IF filter and USB filter

 

Gerald,

Just reporting back...

Unfortunately, that didn't work.? There is a clear difference between V1.2 and my "V2.0" when you spin the knob fast. In .1.2, nochange in display right away, but eventually it jumps. In my code, it just looses the change in the encoder position.? Oh well, have to keep this issue open. But the code you highlighted is exactly the problem area. Thanks again! (and sorry for hijacking this thread)

Re: how can download file x sbitx #sBitx

 

You would have received a full sd card with your kit. For preparing the sd card, you have to use a software called imager available from ?

Re: Some calculations on the IF filter and USB filter

 

Gerald,

Thanks for the pointer! I will give this a try a little later today.

There is a definite "feeling" difference between the encoder working on a nano and that on one of the faster chips. I had played with the threshold for stability and got no where. I quite frankly missed the obvious line comment 10 lines down. :-)

Hi Scott,

If you want to try my latest updates that aren¡¯t merged into Farhan¡¯s main git repository, do this:

1. Open a terminal, execute the following commands...
2. git clone?
3. cd sbitx-k3ng
4.?git checkout 2022.09.06.0115
5. ./build sbitx
6. ./sbitx

This will create a directory separate from the main /home/pi/sbitx/ directory, /home/pi/sbitx-k3ng/ , so you don¡¯t have to worry about some change I made wrecking your mainstream version of sbitx. ?Your desktop and start menu shortcuts for sBitx will still run the mainstream version of the app in /home/pi/sbitx/.

Note that the branch being checked out in step 4 above, 2022.09.06.0115, is the current branch in my repository (sbitx-k3ng) which I¡¯m adding changes to. ?This branch will change in the future. ?When I feel good about the changes I¡¯ve made, I will submit a pull request to Fahran, which allows him to review the changes and merge into his sbitx repository. ?A merge essentially rolls out code changes I made to everyone, and the changes will be propagated to anyone running ¡®git pull¡¯ ?within /home/pi/sbitx/.

If you do the git clone process above to create a sbitx-k3ng repository on your machine, you¡¯ll want to run a ¡®git pull¡¯ frequently in /home/pi/sbitx-k3ng/ to retrieve whatever updates I¡¯ve made recently. ?I¡¯ve been making announcements in the group with the #sbitx-k3ng tag when I make notable changes. ?Make note of whatever branch I¡¯m currently working on, and do a ¡®git checkout {branch name}¡¯ within /home/pi/sbitx-k3ng/ to switch your local repository to the branch I¡¯m working on.

Sorry if I¡¯m covering parts of git you know already. ?Git and Github are really amazing for what they do, but I struggled with both myself. ?They are not always intuitive and can be a bit daunting to understand.

Re: Some calculations on the IF filter and USB filter

 

Hello,
I think that it is only in these lines of code that there is a value to change in order to have a frequence scroll displayed without holes if we turn the encoder a little fast?
there are comments in the programming lines that can help?
it is not of capital importance, for the fun LOL

***
?s = enc_read();
?
? //if time is exceeded, it is recognized as an error,
? //ignore exists values, because of errors
? if (s == 0) {
? ? if (encodedSumValue != 0 && (millis() - encodeTimeOut) > lastEncInputtime)
? ? ? encodedSumValue = 0;
?
? ? lastMovedirection = 0;
? ? return;
? }
? lastEncInputtime = millis();
?
? //for check moving direction
? encodedSumValue += (s > 0 ? 1 : -1);
?
? //check threshold and operator actions (hold dial speed = continous moving, skip threshold check)
? //not use continues changing by Threshold
? //if ((lastTunetime < (millis() - skipThresholdTime)) && ((encodedSumValue *? encodedSumValue) <= (threshold * threshold)))

Jack,

The option was on the version of Arduino IDE that I downloaded.? Here is a link to the Arduino web that explains how to add boards:


The Board is an Arduino Nano.? The processor is ATmega328P (Old Bootloader).

Hi Paul,

As you your question #4, just use your imagination.? Take a look at the manual for the old MMR-40 QRP rig.? They use a PTO made of brass nuts soldered to a PCB just as you describe.
