The simple, one capacitor fix boosts the 10 meters power to a respectable 5 watts on SSB and CW. That is a-plenty to get you contacts. An opening 2 weeks ago, got me a large cache of contacts.

That said, I hear what you are saying about a narrow band design. All engineer is science on a budget. We have to shoot somewhere. The ubitx is an attempt to build an HF general coverge transceiver for $100 dollars. The 109 is with shipping. If you build it on your own, The parts would be even less than $50 dollars. The arduino apart, the only other special chip is the Si5351 that costs a dollar, the rest are in your junk boxes.?

The tricky part is really that the ubitx is an open radio. It is constantly on the move in terms of features and trinkets. If you were to open any active open source project, you will only see bugs reported. That is not because they are more buggy than commercial, standard products. They are less buggier. But they get there by having people constantly discover problems and fix them. This list is a support group as well as development group. It can get intimadating for someone who just joins up. There are some soft landing places like the .

I also understand that there are fierce responses to some proposed changes. We tend to grow comfortable with our choices. Try suggesting to me to switch to a PIC processor from Arduino to see what I mean.?

My personal project this year is to make a 'few bands' transceiver for SSB and CW that is entirely analog. With many bells and whistels including a good agc, narrow band CW filters, etc. This will be a diffcult to replicate project. It is just? personal itch. The uBITX is my third open radio. Earlier, apart from the BITX20, there was also the Minima. The Minima ran into problems, many built it, the receiver was fabulous, the transmitter had spurs. I decided to quit the project. The point I am trying to make is that there is no one radio. The TX power variations from uBITX are not due to it's general coverage architecture but our pick of the IRF510. Other RF transistors are hardly available consistently in the quantities that the uBITX is consuming.?

I hope I have clarified my personal opinions on the uBITX project.

John Smith,

Several thousand people disagree with you.
Not sure why you say it's not worth the price.
What have you found that is a better HF SSB rig for $109 or less?

The single band rig has already been done, if that's what you want.
Buy a half dozen Bitx40's, replace the bandpass filter and the output filter in each,
and update the firmware.? Easy enough, no board hacks, just replacing some
coils and caps.? Or buy one or more of the dozen Bitx variants out there.

Or if you think the uBitx is such a tough sell, create your own kit and make a mint.
Good luck with that.

There.? That's my opinion.

While observing, I have come to believe that the uBITX is a bit of a dud when it comes to power output on most bands, and CW which it is designed for. Too much hacking is required to make it usable, or worth the price. I would like to suggest the idea of individual band transceivers, with specially designed power amplifiers and band filters so a 10 meter BITX works as well as a 80 meter BITX. The Raduino code can be easily adjusted for each band the transceiver is made for, and remains familiar. I realize this would require retooling the factory a bit. But I do recall seeing old connections and silk screening on my BITX 40 where changes have been made. Perhaps some models could have options to populate the board with different filter configurations and finals too. I know you can't get everything on the same board, but maybe some could be dual band for ease of manufacture, or just popularity of use. I would love a BITX 80 or BITX 20 that could put out as much as 25 watts like my BITX 40. And with Allards code and minimal hardware upgrade the CW is wonderful and useful for digital modes too. I don't really mean to poop on your uBITX, but I don't want one at that price. But a $59.00 mono band, or $75.00 dual band transceiver that works well, sounds pretty good to me. Thanks for taking the time to read my opinion.
