So i am on the 4th iteration of this board and I have just about got it right. Kind of sad that its taken me so many goes to get this right, but what can i say. LOL. There is still one bodge wire on the backside of the board because I somehow left off a trace joining one row of push buttons off the 5v line. I am also not sure about the 5V regulator, its running very hot and it should not because its should only have about 300ma running thought it and there is no short to ground anywhere i can find, to explain it running so hot. By hot im guessing its hitting over 60 Deg C as its painful to touch.
Anyway, back to the point of this post. I have gotten back into coding things up and am making inroads. It mostly works now. Pressing the mode button will cycle through LSB, USB and CW. The band button will cycle through 80, 40, 20 and 15m the 4 bands that this radio will support, selecting the appropriate filter banks for both Low Pass and Band Pass filter boards as well as change the IF filter to a narrow CW filter in that mode.
The logger button will put it into logging mode, which along with a keyboard will make log entries and save them to SD Card in ADIF format. The logger is loosely based on my old arduino logger code which can be found in the menu bar above. Though, the code that is going into this is much more refined and polished and fixes most of the clunkyness that was in the earlier versions. I am a much improved programmer now than i was a few years ago when i wrote that code.
The VFO button will exit the logger and put the radio back into VFO mode. I still need to add in a couple more push buttons, one to change the Attenuation setting and the final one to allow changing the TX RX offset. At the moment it is hard coded for a 600hz offset for CW operation, but, i am going to make that variable for real split operation in SSB as well.
Anyway, that is where I am at with this at the moment. When i get things closer to being done, I will probably make a video of all the functions in action to put on youtube. But that is likely to be a couple of weeks away yet. Lots of work to be done in the mean time.
