Re: Variable IF
I'll draw something up, take a picture and post it as soon as I get a chance. I have some other changes, simple ones, that also are worth the effort and I should post them also.

Re: Should we adopt the KD8CEC firmware?
I think it could be done without too much confusion by using preprocessor directives. That way, you don't actually mess with the code; you only change the symbolic constants you wish to affect. For

uBITX40 : power to IRF510
I have already built your BITX40 which I am using with great satisfaction. I have just received your "Micro BITX40". I ask you if I can feed the two IRF510s separately with a higher voltage to get a

Re: Should we adopt the KD8CEC firmware?
This is where problems will begin to occur. Are you going to add in functionality to modify ubitx_menu.ino on the fly? Or are you going to break up ubitx_menu.ino into a lot of little pieces that can

We need a bit more information in order to help troubleshoot your uBITX. 1) Which opto-coupler on the schematic drawing are you referring to as being inoperative? Is it the manufacturer provided

Re: Should we adopt the KD8CEC firmware?
I think it's a great idea to see what we can squeeze out of the existing Raduino with it's Nano by using the KD8CEC code. No changes other than a HEX download for existing uBITX machines (if you keep

Re: Variable uBitx IF bandwidth question
As I've posted elsewhere, I built a K2 a few years back.? It has a variable bandwidth IF filter that looks kind of similar to the ladder filter in the uBitx.? Each node has a 100k pull-up resistor

Re: Should we adopt the KD8CEC firmware?
Allison is right, the SD library is bloated. Perhaps someone can put it on a diet like Jerry did for the Si5351 library. Another point to be made is that, in my experience, it's not the flash memory

Having done a SD interface with Arduino I can say the SD library is huge.? The reason is the typical SD is used with the FAT filesystem and it takes a bit of code to navigate that. If one treats the

Re: Should we adopt the KD8CEC firmware?
A quick suggestion: the idea "up the top of EEPROM" should be defined as a specific offset from the EEPROM base. My reasoning is because I expect different ?C's to come into play over time. This
