Re: Future Ubitx, SWR layout lines on PCB.
Some people do not realize to reach the price point, the ubitx must be bare bones. All these features look good and most likely attractive features and your cost goes up. These brings you into a

Re: uBitx Digi-Interface Module (Add-on Board)
Jim, more power to you! I hope you were able to benefit a lot of people. Overtime, we changed a few of the resistor values to make the system work a little better. You may see this in various

Re: UBITX. FT8 heat sink requirements #ft8 #ubitx
Anyway...my bias is at 110ma per side.? Does that seem appropriate for 24v?? What got you to 36v? What happens to your output power as you increased from 12v to 36v? Thanks for any insight!! Don

Thanks to all of you! I soldered the proper connections and powered up the transceiver with a dummy load. Everything seems to be working correctly, but not prepared with proper antenna yet to make

Re: uBITX V6 heat sink temperature
Joel, I do not have a v6 uBitx, so do not have direct experience with that specific kit.? I do have both v4 and v5 boards, and all do run the regulator hot, especially if I use a 13.8 volt "big rig"

Bert, Thanks for the suggestions. Btw, you can key with the ptt as well. This is in case you need to tune up. One evening, I found Nicaragua on 40m cw and I didn't have the key with me! I quickly
