I'm just amazed of how much priceless information I got in such a short time. Thank you for all users that had answered my questions and gave me even more than that: good advices for the future. Speaking about modifications for the uBitx, I'm not prepared for this task and I'm sure I will leave it as it is. I'll stay for reception mode until I find an SWR-meter and build a dipole. I believe a "random" lenght wire will suffice for just reception. So, thank you very much again and I'm sure we will read us soon because I still have tons of questions but ... one step at the time. THANK YOU!?
