:-) :-) :-) ??? Thanks for the info, middle of the night. . . That means I've got something else to do besides go to the bathroom at 3am! Thanks, Roy WA0YMH

Interesting, Thanks, Roy WA0YMH

PSK-31 I have been working Contestia 4:250 today too. -- 73, W9KJO Walter

The parts that might be RF amps are on the BNC input. I think the box is some kind of demod. Steve, N2FT

In Cura one of the buttons on the left side when viewing the knob will be for scaling. It's been a while but as I recall there are tool tips for the buttons. It'll pop up a dialog which is self

I have the Sotabeam cw DSP filter as a peripheral, using it on another rig, and it is good. ?I tried it on the uBitx and it is a definite improvement. ?However, I'm also going to try my old

Those Knobs were designed for the FemptoBit 2000 GHz Radio!? Made for Flea Hams! It is all in scaling, Cura may think the units are MM?.? In inches the tuning knob is 1.2".? The volume is

Mike, Once the Arduino IDE opens up and you can see all the code, make sure you have the Raduino plugged into a USB port and then go to the upper tab named 'Tools" and choose "Board" then select

Hi Jim, May I ask what you chose to use in place of your Raduino boards?? Justin N2TOH

Stephen:? Glad you scored a couple of the cases.?? Have not seen a better case for the uBitX or BitX40. One of the best things about the case is way it is constructed. Pulled down all of the cases

Should work fine, as suggested in post 42723 a few days ago: ? ? If really paranoid, perhaps add an 8 or 9v linear regulator (or string of diodes) to reduce Vcc into the TDA2822M. Though I'd now

Batch 3 .. First we have heard that there was another batch in production! I will add your photo to the display of "damaged goods" on ubitx.net! Mike ZL1AXG -- Mike Woods mhwoods@...

Michael, I'm a 3D printer noobie and literally just got a monoprice printer this week. I've tried to load your two knobs stl files that you shared into Cura to generate the necessary gcode. The first

I have some TDA2822 replacements ordered and will try them, but the adapter with the LM386 is working well, though the adapter will fall out of the socket if the rig is vibrated much. ?If I decide to

How about stacking a few 1N4001s in series in the power rail to the?TDA2822 ? Not ideal but could provide a couple extra volts headroom and easier to install than a regulator. Paul ZS2OE

Since Nick's PC board?(VK4PLN) ?isn't available yet, I solved the problem using an inexpensive filter from QRPme. ?I inserted it in line where Nick did. ?Now I can work on the next uBitx

Here is what's left of mine.? Sorry for the large image.? Number on my board is 036/03.

Interesting developments.? Dodgy relays and IC's occur every so often due to the vagaries of batch testing but nothing will sink a new product design faster than a consistent QA problem at component

I don't use a Mac, but I assume it's the same. Click File --> Open on the Arduino IDE menu. Navigate to the directory named ubitx_20 and click on it. Then double-click on the file named ubitx_20.ino.

Joel, I am new to this and haven’t had time to read Jack’s book that I just purchased. I am using a Mac and did the steps you listed. Once Arduino is up, what steps are next to load the
