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

Anyone?

Try again next week?

Regarding this contest, I forgot to mention -- you may enter as many times as you like (different name for each entry though).? In case the winning entry is duplicated by another person, the earliest

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

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

This is a good idea and might make it easier to peel off those features not desired. The source already lends itself to this approach. I have not studied it closely enough to know whether specific

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

In fact, to expand on this… I think Ian should consider block defines for sections of the code that people want or don’t want. He has already done this in selecting the type of display (2 line or

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

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

That was amazing, Allard! I will be passing that on to some friends. Thanks for sharing that with us!? N5KNG

Hi Tom, Is it possible for you to provide a sketch of the circuit, so we can be sure to understand what you've done and get it right when we hook it up on the board? If not, then perhaps a little more

Dear Konstantinos, We need about 4 months of lead time to change the circuitry, given the lead times for the PCBs, availability of the SMD pick and place, etc. Instead, we are looking at what we can

I do not see any issues with the EEPROM. Everyone protects the first 32 bytes as "stock" delivered from factory. All calibration routines place new values there. Maybe the factory should store a copy

Hello folks, could anyone describe where to connect those wires form the AGC circuit to the BITX40 pcb? Photos would also help a lot. I just got mine BITX40 recently and now I'm in the process of

Ha! I was wondering what happened. I must have done this by accident as well! Thanks!
