From 2016-05-21 04:00 to 16:00 the carrier at Cumiana was 14.6 db in 23.15 uHz. This is after a stage of vorbis compression so might be a dB or so better in the raw original. Good for 5 chars at 84 seconds for Eb/N0 = 0.0 dB. Cumiana is very sensitive and wideband. Currently holds the VLF detection distance record at 8822Hz of 7173 km from W4DEX. -- Paul Nicholson --
