Tweeks and Whistlers Recorded on this Grabber
You need real radio ears for this recording of GBR Rugby UK. It was accidentally recorded when Mike Oldfield recorded Tubular Bells at Manor Studios in Oxfordshire
July 27th 2011. Warm dry winds produced signals at around 1.5kHz due to static charge
July 7th 2011. Rain with static charge causes heavy noise on VLF
HF Sferics on Saturn as heard by Cassini (the one file not recorded on this Grabber) Speclab analysis by G3ZJO
