Re: Ubitx Ver 6 need PTT circuit for Linear AMP

Howard Fidel

I just redid my uBitx with a 70 watt amp. For the filters, I redid the filters on the uBitx with larger ferrrites, and  100V caps. I route the uBitx amp output before the filters to the amp, and then the amp output to the uBitx filter input. Works just like the uBitx barefoot, but with higher power when the amp is switched in. The amp has a relay for in/out.
