The uBitx has a 12mhz BFO. We have trouble on the uBitx with either the 12mhz USB port oscillator or the third harmonic of the 16mhz processor oscillator wreaking havoc with the receiver.? Could be

Maybe I’m missing something here but I just put each downloaded version in its own folder and have no problem with overwriting files. Mike K5ESS Sent: Monday, April 23, 2018 10:45 PM To:

No way should anyone hate anything.? It may be an eye opener to some what can be done with a modern micro-controller.? I am glad Jack gave honorable mention to the Protoneer.? Before I ordered it

Thanks Howard for letting us know, I’ve made signal measurements at various points in the RF amplifier chain and on all the bands so that I can compare results of the mods. Skip Davis, NC9O

Im not sure you understand this completely, so ill put this more clearly. When the main sketch has the same name from version to version and you upload it to the Arduino IDE, it over-writes the

This is great Bob, what is the original file format you're working in? Can you also share that in the files section and|or also make a PNG version available? If the original version is in a format

MV109 ... email is ai4ot@...<mailto:ai4ot@...> Thanks Leonard! Your videos helped me to understand so much when I first started with the bitx radios. I’ve got a 6:1 reduction drive on the

I've modified many 20a's using the directions on my web page. http://golddredgervideo.com/kc0wox/bitx20amods/varactormod.htm The key is the varactor. I would guess that the one you have doesn't give a

I have gone off the deep end with by uBITX.? My current configuration, basically a rats nest on the bench is: * Main CPU (Teensy 3.5) handles the SI5351 control (I2C), the 20x4 LCD Display (I2c),

I’m using the 78L08 and mv109. I may revert back to the capacitor and fine tuning pot. The real problem I had was stability, which I have now. 72/73 de Chas ai4ot

Yep, every one is different and, man, are you gonna hate the Jackal board: Jack, W8TEE

One more item............. I think it really supports the hobby when hams like Don, ND6T, provide a uBIT-X solution for something requiring a small board (like his AGC fix) and he also provides a

In varactor tuning, your goal is to maximize the capacitance variance from one end to the other. Therefore, the real questions are two: what varactor is being used, and what is the voltage range it

HI Jack, Have you considered the Asus Tinker board?? Same form factor as Rpi but even more capable.? Does cost more as well.? Quad core 1.8GHz, 2 Gb memory, Gb ethernet, 24 bit 192khz audio,

Thanks Ian for all your work you sure are packing a lot of features into that nano. I first modified the original firmware of Farhan’s to fix a few issues I had with it and then I followed your

Jack, I agree that there are many people standing on Farhan's shoulders and he has certainly created/generated a huge interest in his uBIT-X design point..... key parameters being that the cost is

Hi Bob, Thanks for that great work to provide a clear diagram for the uBITX connections. It highlights a point of possible confusion that will probably need to be clarified higher up the pay grades

William I use git for version control, but it seems to be difficult to trace history when the file name changes. Instead, I will create a separate file to keep track of which files have changed each
