Re: My uBitx with 5v mod #ubitx



Do a test. disconnect the unit from the load aka xBitx. Check the output voltage with the jumper not
installed. Like you accidentally knocked it off!!

If the voltage is more than 5 then hardwire the jumper and solder it. Better safe than sorry.

I used this UBEC @ 5v

It has a small metal screen around it and the ferrite on the 5v output lead plus capacitor on the uBitx board (where I cut the track and soldered the 5v lead onto) forms an adequate LC filter on the 5v DC.
I can't detect any 'noise' on Rx, but as yet haven't transmitted.

I use the UBEC on model aircraft with a video transmitter (FPV) and don't see any noise in the signal.
The video transmitters are quite susceptible to 'dirty' DC and often shows as 'herringbone' lines in the received video.
