Time to come clean and confess. I saw a 5v DC-DC downconverter with a USB charging port. So I put it in. Now my beloved Franken-BITX charges my cell phone, as well as bringing peace to the Middle East

Rick - I did exactly this. One DC-DC converter to make 12v for the board and externals which need 12v, and another smaller DC-DC converter to make 5v for the nextion screen. Two keys here: I put them

I'm not admitting to direct hands on experience with this, but...it is possible to accidentally leave the coax off the antenna side the SWR meter. So it might look like the ubitx is plugged in to the

Yes. Lots of folks go direct computer audio i/o to uBITX o/I. The great AF suggested this. You have to really control (aka lower) the computer output level to match the unit's expected mic input level

The uBITX is a great digital mode radio due to CAT control and ease of audio plumbing into your computer. Using digital modes, the 10W or so output, plus a fair antenna, is sufficient for ample geogra

You have as many choices as there are antennas limited only by your circumstances. With my uBITX, I knew I wanted a multiband antenna, and I would happily accept the inevitable tradeoffs inherent in s

I've re-read this over and over. Each time I say to myself....I...must...understand and internalize this material...there is secret knowledge here...get it in your bean now!!! which is all to say two

Mark -- same boat here. I couldn't stand all the Jack pulling and plugging to "switch between digital and audio". So I put in a simple dpdt mini switch with the board inputs on the center, and the usb

My 2 cents...I've asked a few fairly newbie questions more than once, and this group has been kind, patient and helpful. Early in my journey, being totally frustrated at my clear inability to get my u

Bob, I have a few old computer power supplies around. Two questions...what magic does the 10ohm on the 5V output do? Does it make the PSU think it is hooked up, so it will turn on? Also, compared to a

here are my settings for a related app connected to my uBITX. I used a AtomicPi/Lubuntu for a while, then moved to a WIN10 box. And yes, 38.4 is the required speed to talk to the arduino (I think). Ca

Shaun, if you were using your ubitx, then we had a ubitx to ubitx wspr moment!

Yes, 160M uBITX operations without a LPF is a problem. But like my kids are fond of saying...."I only did it once!" Which is clearly not true...but using only a few watts...and infrequently...well....

#ubitx

Can a uBITX operate successfully on 160M? Oh my YES. Here is a demonstration where a humble V4, made with paper clips and duct tape, broke an obscure 160M PSK contest called the "160M Great Pumpkin PS

So here is a short vid of the uBITX after repair and dummy load testing. On the bench, it seemed to work. https://photos.app.goo.gl/9zZ3QAr9Bzn4G2NL6 To set the Bias, I learned you should have a anten

Dave -- I switched the fan 'cause even the slight noise annoyed me. And switching seems just more elegant. But does it actually "work better"? Easy to answer that one: no. Hahahah. And the irony aboun

You question the parentage of my 510? Their father was Mr. Vishay and the mother was a Mouser. Sniff sniff sir! (Hahah) Okay, as a self taught rube, who believes trial and error is the righteous path,

#ubitx

Haha....yes a slow learner. Some of us practice the right way, and the rest of us practice the mistakes. Hahah.

#ubitx

I learned to install the heatsinks first, then put the 510s into the board. Installing the heatsinks off board allowed me to add the thermal compound (aka heatsink goo) and then torque down the screw

#ubitx

Turns out that large heatsinks and fan are not enough to triumph over failed power supplies, non-resonate antennas, too much current, too long digital TX sessions, and a bit of careless operations....
