Re: Mini PA für my uBITX #ubitx
Thank you Brian.
I tend to forget to switch antennas when changing fom 40/80m to higher bands and blew up a few finals in the past, so the code in the amplifier demands a low power tune after band changes.
When transmitting and high SWR occurs, PTT is disabled.
ATT is enabled on 20-80m as my ubitx puts out more then 5W on These bands.
Will gladly share all details when interested,
