The technique using WWV is more than good enough if you keep one thing in mind. The mater osc referenced to the crystal osc is the source for the HFOm IFLO and BFO so they all move if the master OSC?

My wife had watched me carefully collecting (inexpensive) parts to build a uBitX over many months. When she heard about Ash’s ‘elves are busy’ post,she game me the $$$ to buy one. It’s been

I have bought this one:

I seem to have missed this simple capacitor replacement for more power hack. Is there a chart of higher power at higher frequencies? Other boards have solutions of using different finals and some

Indeed I have always said folks need to be more appreciative of what they are getting here and less ready to bicker/moan about stuff. Its an awesome little radio and provides freedom for those who

I was with you until the split… The world is full of split…. In this case, I don’t see how you can split the software, from the hardware as there is no blurry line, no sharp distinct line

Hi Gordon, I've been down the power path.? As a very active VHF/UHF op I have power to the 350W region? from HB amps.? Its a lot of "drillin and blastin" goes into making them.? I have 4 HB radio

Agreed! ?I'm still struggling getting audio levels right. It's hard to turn my nearby icom 7300 down low enough to see a clean signal. On FT8 soon Bo W4GHV since '54

I thought the same, I even checkd the polarity with a battery just to make sure. Yes the encoder pins are OK.

With all the mud in the water these past few days, I figured I would share something positive.? Lately I've been playing with FT8 on my ?BITX.? I am more interested in learning as much as I can

I found that wrapping the interfering ps with aluminum foil (in case ground it) solves most of it. $6.64. I have read that some could interfere with our radios. I wanted to shorten the 12v cable. I

I use industrial closed frame power supplies as they can be had cheap.? However very few are quiet in the raw.? My solution is a aluminum diecast box with CORCOM filtered line input with added

Arv I have to say this is the best post on this subject in quite some time. It certainly seems that the original firmware could use some improvement/updating. Does it need all the additional features

"If your inclined look in the files area of this forum under KB1GMX, there are two files called HF-use-Fet 1 and 2. Its fairly simple and if built well its a solid amp. Pay attention to the mechanical

Some are worse than others.? The power supply for my laptop raises the noise level 1.5 S units on all the HF bands, but the one on my HD monitor completely wipes out the 20 meter band and no

I second that and of course a built-in tuner would be nice too! rOn

Does anyone have a simple way to calibrate the uBITX when a good service monitor is at hand ? I know the unit will not be super stable and don't expect it to be. I have a service monitor that I know

Interesting that this single subject has generated more comments than any other topic. Some comments are on-topic (*Should we adopt the KD8CEC firmware?*) while others seem to have drifted off into

I used a powersupply similar to yours that came with a chinese CCTV system also provides 12V/5A. So far haven't had problems with noise generated by the powersupply. John

Maybe the next logical step is to convince Ashhar that instead of a new radio, his next offering should be the uBitAMP.
