This is my very first spectrum recording using my new Flex 1500 SDR. The antenna used is an AOR LA-400 amplified loop. I’ll be adding to this collection of stations I’m monitoring. Video quality will improve with time. Please feel free to comment on my videos and share your experiences monitoring the LW, MW and HF bands. 73-
