finally after all the years running a stock 20A I’ve done the voltage stabilizing mod and the varactor tuning mod with a 10turn pot, and I think I’ve worked out the L7 windings now to get into the

To continue a little further.....I see those who are interested in DSP and other number crunching applications will require a RPi, Teensy 3.5/3.6, or STM32F4xx/STM32F7xxx microcontrollers for

I see the complexity and cost growing exponentially. That's fine but I really don't see the uBIT-X as suited for going in that direction. It depends. If you can fabricate a

I said almost the same thing a day or two ago...it has some really nice features, like a 12-bit ADC (4096 instead of 1024). Another important plus is that it can be programmed and run in the Arduino

Back when I was in school, I once wrote an essay with a manual graphite display generator. Jack, W8TEE

Jack Well said. New tech license holders have a low cost incentive to get their general ticket and be able to join the community without fear of a steep investment. Art - N2AJO

I put a SotaBeams DSP Audio Filter into my BITX40 and it works great. I have a 2nd one that I intend to use for my uBITX. If you don't want to fuss with installing it in the rig you can get an

Yep, with a #2 on it. Jack, W8TEE

I wish to apologize for my statements on the list last night. I'm not going to make excuses. I shouldn't have said what I said and I know it. I'm likely to ask some stupid questions as I go along

Ian... would you PLEASE consider writing the version number in the file name of the code? That way different versions can be saved easily in the Arduino ISD. Dr. William J. Schmidt - K9HZ J68HZ

​ The ability to change course --- a mark of true character. Cheers, gordon

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

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

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

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

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

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
