I am still awaiting an exam date for my foundation exam (UK) and have been patiently putting together my first aerial, an EFHW80-10 which has been tricky due to my restricted garden size (tiny) Yesterday I finished the build and got it up. Now, I know I can't (and won't) transmit voice etc as no license yet but I did admit on the group that was helping me build the aerial that I pressed the AMU button on my rig - a Xiegu G90 just to see if it tuned on one band ok, it did. The AMU takes much than 2 seconds on this radio AND it was set for 1W RF output, I also followed procedure and made sure the freq was clear, the band I chose is completely dead here at that time anyway. So, having admitted this rookie mistake I am now being hammered by the group "internet police" for breaking a ham rule etc. Is it that serious - did I commit a cardinal sin here? For the response I got you would think I admitted to running a pirate radio station at 500W 24/7!
